DESC:RADIATION-BASED DECONTAMINATION APPARATUS
Field of the Invention
[0001] The present disclosure generally relates to radiation-based decontamination apparatus. Further, the present disclosure particularly relates to radiation-based decontamination apparatus.
Background
[0002] The background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] Spectacle sterilizers are associated with the general field of sanitation devices applied to personal optical accessories. Eyeglasses are exposed to frequent handling and airborne contaminants, making them susceptible to microbial colonisation. The presence of bacteria, fungi and viruses on optical surfaces such as lenses, frames and nose pads introduces a health hazard to users. Contamination of eyeglasses increases the likelihood of microbial transfer to the eyes, nasal cavity and facial skin. Various cleaning techniques and sterilization systems have been introduced to address microbial contamination associated with eyewear.
[0004] A commonly known method for cleaning spectacles involves the manual application of microfiber cloths. Such cloths are typically used to wipe lenses and frames to remove dust, oils and fingerprints. However, such cloths are incapable of eliminating microbial agents from complex structural areas such as frame hinges and nose bridges. Manual wiping lacks the ability to destroy bacteria or viruses embedded in surface microtextures. Furthermore, the reuse of contaminated cloths may lead to cross-contamination, further exacerbating microbial transfer to the eyewear.
[0005] Another known cleaning approach uses alcohol-based chemical sprays and wipes. Such chemical disinfectants act by denaturing proteins and disrupting microbial cell walls. However, prolonged exposure to alcohol and similar agents degrades optical coatings applied to lenses, such as anti-reflective, photochromic and scratch-resistant coatings. Chemical residue left on the lenses also contributes to user discomfort and may impair visual clarity. Additionally, the environmental burden associated with disposable wipes and chemical effluents poses sustainability concerns.
[0006] Certain ultraviolet radiation-based disinfection systems have been introduced to sterilize various objects including personal accessories. Ultraviolet radiation in the UV-C spectrum is known to exhibit germicidal properties by disrupting nucleic acids in microorganisms. However, available UV-C devices are predominantly bulky enclosures developed for hospital tools or surgical instruments. Such devices are not dimensioned to accommodate spectacles and often require supervision or specific training for safe use. Moreover, radiation leakage due to incomplete shielding poses risks of dermal or ocular injury, making such systems unsuitable for routine domestic use.
[0007] Steam-based and heat-based sterilization systems are also known. Such systems rely on thermal exposure to deactivate microbial agents. While such systems are widely used for metallic surgical instruments and industrial components, such systems are unsuitable for optical products. Heat exposure damages plastic-based frames and affects dimensional stability of curved lenses. In addition, lens coatings degrade under repeated thermal cycles, rendering such systems unsuitable for preserving the functional and aesthetic integrity of spectacles.
[0008] Some portable UV devices available in the market are designed to accommodate mobile phones or accessories with flat profiles. Such devices typically employ a single emitter and rely on reflective panels to distribute radiation. However, the geometries of spectacles include concavities, hinges and bridge elements that remain shielded from direct radiation in such systems. As a result, incomplete exposure leads to inconsistent sterilization, and microbial agents remain viable on partially exposed surfaces.
[0009] Battery-powered sanitization pouches with LED-based UV sources have been made commercially available. Such pouches often lack rigid internal support or orientation control for the object being sterilized. As a result, spectacles placed loosely within such pouches undergo positional displacement, which leads to uneven radiation distribution. Moreover, the flexible material construction of such pouches fails to provide sufficient enclosure sealing, increasing the possibility of UV leakage during operation.
[00010] Various cleaning stations installed at optical retail outlets provide ultrasonic cleaning services. Such systems use high-frequency vibrations in a liquid medium to detach contaminants from lens surfaces. While ultrasonic cleaning is capable of removing particulates, such systems are not effective in microbial inactivation unless accompanied by high-temperature cycles or chemical additives. Furthermore, such systems are not available for personal use and require external assistance, making them unsuitable for frequent or domestic application.
[00011] In light of the above discussion, there exists an urgent need for solutions that overcome the problems associated with conventional systems and/or techniques for sterilizing spectacles.

[00031] Pursuant to the "Detailed Description" section herein, whenever an element is explicitly associated with a specific numeral for the first time, such association shall be deemed consistent and applicable throughout the entirety of the "Detailed Description" section, unless otherwise expressly stated or contradicted by the context.
[00032] As used herein, the term “radiation-based decontamination apparatus” refers to an apparatus that facilitates the sterilization or microbial decontamination of an object using non-contact radiation. Such radiation may include ultraviolet, far-ultraviolet, or extreme-ultraviolet wavelengths commonly associated with germicidal properties. Examples of radiation sources include ultraviolet-C light-emitting diodes, low-pressure mercury lamps, and excimer lamps. The apparatus may operate in dry conditions without involving chemical cleaning agents or heat, making it compatible with sensitive materials. Said radiation-based decontamination apparatus may be adapted for personal items, including spectacles, wearable accessories, and other articles prone to contamination. The apparatus may also be applicable in medical, commercial, or residential settings. The radiation exposure targets biological matter, such as bacteria, fungi, and viruses, through nucleic acid disruption or protein denaturation. The radiation-based decontamination apparatus may be housed in a container or device structured to control user access, timing, and radiation dosage. The radiation emitted within the apparatus performs germicidal action on exposed surfaces, reaching inaccessible regions based on radiation distribution and enclosure design.
[00033] As used herein, the term “container body” refers to a physical structure forming the primary housing of the apparatus. Such container body defines a spatial region wherein items are positioned for decontamination. The container body may be fabricated from non-reactive, durable, and optically resistant materials such as high-density polymers, coated plastics, or metal composites. Structural examples include rigid enclosures, hinged cases, and sealed boxes. The container body may comprise integrated sealing features, hinges, or latching mechanisms for controlled access. Said container body is dimensioned to enclose the internal cavity and withstand repeated operational cycles without degradation. The material composition of the container body is selected to resist degradation by ultraviolet radiation and provide insulation against thermal or electrical risks. The container body may also support mounting structures for internal assemblies, wiring pathways, and reflective surface integration. The shape and form of the container body are influenced by the objects to be sterilized, such as eyewear frames or other optical accessories requiring full enclosure.
[00034] As used herein, the term “internal cavity” refers to an enclosed space defined within the container body where the object intended for decontamination is placed during radiation exposure. Said internal cavity may be structured in a manner that allows complete enclosure of the object with minimal free space to reduce diffusion losses. The internal cavity may include surface contours or recessed profiles adapted to accommodate varying geometries of objects such as spectacles, watches, or similar accessories. Reflective lining materials such as aluminium foil, PTFE film, or specialised coatings may be applied to the internal cavity to redistribute incident radiation and eliminate shadowed zones. The internal cavity may also feature passive alignment guides or support fixtures that maintain the spatial orientation of the object. Said internal cavity is generally opaque to the emitted radiation to prevent transmission or leakage. The cavity dimensions, material reflectivity, and internal layout are selected based on the optical properties and design constraints of the decontamination system.
[00035] As used herein, the term “closure member” refers to a movable structure that operates to seal or unseal the internal cavity of the container body. The closure member may include hinged covers, sliding panels, or detachable lids. Examples of closure members include snap-fit polymeric lids, magnetic flaps, or gasket-sealed hatches. The closure member may be composed of UV-resistant materials to withstand radiation exposure from internal sources. The closure member may incorporate mechanical alignment features that facilitate complete and uniform sealing of the internal cavity. The closure member may serve a dual role of physical barrier and triggering element for initiating or terminating radiation emission. Sensors or switches may be operatively connected to the closure member to detect its position and state. The presence of a closed closure member may be a necessary condition for enabling other components of the decontamination apparatus. Said closure member is positioned in direct contact with the container body to form a complete enclosure around the internal cavity during operational phases.
[00036] As used herein, the term “radiation emission assembly” refers to a collection of components responsible for generating and directing radiation toward the item placed within the internal cavity. Said radiation emission assembly may include light-emitting diodes, mercury vapour tubes, or plasma discharge sources capable of emitting ultraviolet or similar germicidal radiation. Light-emitting elements may be mounted on circuit boards, frames, or reflective supports positioned within the internal cavity. The emission assembly may provide unidirectional or multidirectional radiation exposure based on the arrangement of emitters on different walls or surfaces. Examples include arrays mounted on the top, bottom, or side walls of the cavity. Electrical control of the radiation emission assembly is facilitated via direct connection to a control circuit. Radiative output may be limited to a specific wavelength range for targeting microbial agents such as E.coli or Staphylococcus species. Heat sinks or passive thermal conductors may be integrated with the emission assembly to prevent thermal damage to the container body or supported objects.
[00037] As used herein, the term “control circuit” refers to an electrical system arranged to regulate the operational timing and activation of the radiation emission assembly. The control circuit may include microcontrollers, timer circuits, voltage regulators, and relay drivers. Examples of microcontrollers include integrated circuits such as AVR, PIC, or ARM-based processors. The control circuit may be programmed to execute predefined operational cycles based on user input or sensor feedback. Such cycles may include fixed-duration irradiation periods followed by auto shut-off to prevent overexposure. The control circuit may receive enabling signals from detection switches or safety interlocks associated with the closure member. Additional components of the control circuit may include indicators, display elements, or user-interface modules. The control circuit is arranged to maintain power efficiency, prevent erroneous activation, and regulate output levels of the radiation emission assembly. Said control circuit operates in conjunction with the power input interface and detection switch to maintain controlled sterilization conditions.
[00038] As used herein, the term “detection switch” refers to a sensing device that detects positional status of the closure member and provides a corresponding electrical signal to the control circuit. The detection switch may include limit switches, reed switches, Hall-effect sensors, or capacitive proximity sensors. Said detection switch is operatively coupled to the closure member and located such that movement between open and closed positions alters the electrical state of the switch. When the closure member reaches the closed position, the detection switch transitions to an activated state, allowing the control circuit to initiate a sterilization cycle. Conversely, any displacement from the closed position causes the switch to deactivate and interrupt operation. The detection switch functions as a safety feature by preventing emission of radiation when the enclosure is not fully sealed. The physical form of the detection switch may vary based on spatial and electrical design considerations but performs a similar gating role in all configurations.
[00039] As used herein, the term “power input interface” refers to the electrical connection mechanism by which external electrical power is supplied to the control circuit of the decontamination apparatus. Examples include USB Type-C ports, barrel connectors, or AC-DC power input terminals. The power input interface may accept input from standard USB power supplies, rechargeable battery packs, or plug-in adaptors. Voltage and current ratings are specified based on the load requirements of the control circuit and radiation emission assembly. In certain configurations, voltage regulators or power filtering circuits may be integrated within or adjacent to the power input interface. Physical placement of the power input interface is typically on the outer surface of the container body for accessibility. Said power input interface establishes the electrical pathway required to activate internal assemblies and operate the apparatus under controlled conditions.
[00040] As used herein, the term “reflective inner surface” refers to a coating, layer, or finish applied to the internal surfaces of the cavity that facilitates the redirection or redistribution of radiation toward various orientations. Such reflective inner surface may be constructed using metallic coatings such as aluminium, silver, or gold, or polymeric films such as PTFE or reflective PET. The reflective inner surface may exhibit high reflectance in ultraviolet-C wavelengths and may be applied through processes including vacuum deposition, lamination, or chemical coating. The purpose of the reflective inner surface is to minimize radiation losses and to distribute radiation evenly over curved or recessed surfaces of the object placed inside the cavity. The material selection is based on optical compatibility and durability under repeated radiation exposure. The reflective inner surface may also reduce the requirement for high emitter power by increasing the cumulative exposure through reflection. Surface smoothness and reflectivity coefficients are considered during material selection.
[00041] As used herein, the term “light-emitting elements” refers to radiation-generating components mounted within the cavity that emit energy in the form of ultraviolet or similar radiation. Such light-emitting elements may include UV-C light-emitting diodes, miniature fluorescent UV tubes, or gas-discharge lamps. The light-emitting elements may be mounted on opposing cavity surfaces to achieve multidirectional exposure. Electrical interconnection of the light-emitting elements is provided through printed circuit boards or wired assemblies, and heat dissipation components such as metal cores or passive fins may be included to prevent overheating. Emission characteristics of the light-emitting elements are defined by wavelength range, intensity output, and angle of dispersion. The arrangement of the light-emitting elements affects the uniformity and penetration of radiation across the item being sterilized. Light-emitting elements may be operated individually or in groups based on control logic from the circuit. Mounting position, number of emitters, and radiation pattern are determined based on cavity geometry and object type.
[00042] As used herein, the term “removable support tray” refers to a structure placed within the cavity on which the item to be decontaminated is rested. The removable support tray may be fabricated from non-abrasive materials including silicone, soft polymers, or cushioned composites to prevent surface scratches or coating damage to delicate objects. The tray may be structured with slots, ridges, or contours that maintain object alignment and prevent motion during the sterilization cycle. The tray may be detachable to allow cleaning, replacement, or reconfiguration for different object geometries. In some designs, the tray may include perforations or transparent sections to avoid obstructing radiation paths. The tray may be positioned on raised platforms or brackets to facilitate exposure from multiple angles. The design of the removable support tray takes into account the shape, size, and weight of objects placed for decontamination, ensuring appropriate support without interfering with radiation effectiveness.
[00043] As used herein, the term “sealed geometry” refers to the spatial and structural arrangement of the internal cavity and container that prevents radiation leakage during operational phases. Such sealed geometry may involve interlocking edges, compression gaskets, or magnetic sealing mechanisms applied at the interface between the container body and the closure member. Sealed geometry may also be achieved through rigid overlaps or moulded contours that close all optical gaps when the closure member is in the shut position. The purpose of the sealed geometry is to ensure that radiation remains confined within the apparatus, thereby eliminating exposure risk to the external environment. Sealing may also contribute to maintaining internal reflectivity and thermal balance. Materials selected for sealing purposes are compatible with ultraviolet exposure and resist ageing, shrinkage, or detachment over operational cycles. Design tolerances are defined to achieve continuous sealing without over-constraining movement.
[00044] As used herein, the term “wavelength range from 265 nanometres to 280 nanometres” refers to the spectral output range of the radiation emitted by the radiation emission assembly. Radiation in this band is generally classified within the ultraviolet-C spectrum, which is known to cause disruption of microbial DNA and RNA, leading to inactivation. Emission in this range may be generated by semiconductor diodes, mercury vapour lamps, or pulsed light sources. The specific wavelength range is selected for its high germicidal efficiency and reduced ozone generation compared to shorter wavelengths. Materials and coatings used within the cavity are selected to reflect, transmit, or resist degradation at this wavelength band. The emission wavelength is calibrated using optical filters, band-pass layers, or LED binning. Devices emitting in this range are used in medical, laboratory, and consumer sterilization products due to their ability to reduce colony-forming units of bacteria, viruses, and fungi upon exposure.
[00045] As used herein, the term “optical devices” refers to wearable or handheld articles used for visual assistance or protection that may be subjected to microbial contamination during use. Such optical devices include spectacles, sunglasses, reading glasses, or safety goggles. Optical devices may consist of frame elements, lenses, nose pads, temple hinges, and coatings such as anti-reflective, photochromic, or scratch-resistant layers. Due to direct contact with skin and proximity to facial orifices, such devices require regular decontamination. The cavity dimensions and radiation exposure patterns are selected to accommodate such optical devices without causing physical deformation, optical distortion, or coating damage. Structural features such as lens curvature, hinge locations, and bridge dimensions are taken into consideration while shaping the cavity and positioning internal elements.
[00046] As used herein, the term “geometrical features of optical accessories” refers to structural contours, angles, and form variations found in eyewear and similar items. Such geometrical features include bridge curvatures, nose pad contours, lens recesses, frame borders, and temple hinge cavities. These features create complex surfaces and shaded zones that may not be uniformly exposed to unidirectional radiation. The cavity structure and emission assembly are arranged to deliver multidirectional exposure targeting such features. Shaping of internal surfaces or incorporation of reflective geometry may assist in directing radiation into recessed or obstructed regions. The geometrical features are accommodated by aligning the object in a specific orientation or by shaping the tray or cavity contours to conform with expected object dimensions. The aim is to achieve comprehensive surface exposure while preserving the structural and optical integrity of the accessories.
[00047] As used herein, the term “partial movement of the closure member after initiation of a sterilization cycle” refers to any displacement or unseating of the closure member while the radiation emission assembly is active. Such movement may include lifting, shifting, or loosening of the closure member that breaks the seal or alters the positional engagement with the container body. Detection of partial movement is achieved using sensors or switches that respond to loss of contact, light penetration, or magnetic decoupling. When such movement is detected, the control circuit is arranged to deactivate the radiation emission assembly to prevent escape of radiation. The detection mechanism may operate independently of the initial closure detection and may function during any point of the cycle. Safety and compliance with operational standards are maintained by terminating the radiation emission upon any movement indicating user interference or improper sealing.
[00048] As used herein, the term “passive ultraviolet intensity equalizer” refers to a non-emissive structure located within the cavity that functions to moderate radiation intensity distribution from opposing light sources. Said equalizer may include diffusing panels, baffles, or reflectors that scatter or redirect radiation to balance localised concentrations. Such components are constructed from UV-resistant materials such as quartz glass, coated plastics, or diffuse reflectors. Placement of the equalizer is determined based on emitter positions, cavity size, and anticipated reflection paths. The objective is to reduce hot spots, avoid overexposure in certain regions, and maintain uniform dosage across the surface of the object. Passive ultraviolet intensity equalizers are static structures with no active electronics or moving parts and may be detachable or fixed. Optical modelling or field calibration may be used during design to optimise equalizer geometry for the target radiation pattern.
[00049] FIG. 1 illustrates a radiation-based decontamination apparatus (100), in accordance with the embodiments of the present disclosure. The radiation-based decontamination apparatus (100) includes a control circuit (110) electrically connected to the radiation emission assembly (108) and arranged to manage its operation during a predefined cycle. The control circuit (110) may comprise a microcontroller, programmable timer, or logic-based integrated circuit capable of executing instructions to control activation and deactivation of the radiation emission assembly (108). The control circuit (110) may receive input from a user interface, such as a button or capacitive sensor, or from one or more internal switches or sensors. The control circuit (110) is programmed to initiate a sterilization cycle of a specific duration, for example, a cycle lasting more than ten minutes, upon confirmation of appropriate conditions including power availability and closure detection. The control circuit (110) may include timing mechanisms, signal conditioning components, current regulation elements, and protective circuits such as fuses or diodes. The output of the control circuit (110) drives the radiation emission assembly (108) through transistor switches, relays, or driver ICs depending on the power requirements of the emitters. The control circuit (110) may also include provisions for feedback indicators such as light-emitting diodes or audible alerts to indicate operation status, cycle completion, or fault conditions. The layout of the control circuit (110) may be on a single printed circuit board or distributed across interconnected submodules mounted within the container body (102). The control circuit (110) may include non-volatile memory elements to store parameters or operation logs and may be programmed through a physical interface or via firmware flashing. Upon expiration of the predefined cycle, the control circuit (110) is configured to terminate power delivery to the radiation emission assembly (108) to prevent unnecessary exposure and to conserve energy. The control circuit (110) provides the operational logic for regulated and safe radiation delivery in accordance with input and internal states.
[00050] The radiation-based decontamination apparatus (100) includes a detection switch (112) operatively coupled to the closure member (106), wherein the detection switch (112) is positioned to enable the control circuit (110) only upon detection of the closure member (106) in a closed position. The detection switch (112) functions as a safety interlock and operates to sense the mechanical state of the closure member (106) with respect to the container body (102). The detection switch (112) may be implemented using a mechanical contact switch, magnetic reed switch, Hall-effect sensor, capacitive proximity sensor, or optical interrupter. In operation, the detection switch (112) is placed at a location within or adjacent to the closure member (106) such that transition from the open to the closed position activates the switch. Upon activation, an electrical signal is delivered to the control circuit (110), confirming that the internal cavity (104) has been securely enclosed. The control circuit (110) is then permitted to initiate or continue the sterilization cycle by enabling the radiation emission assembly (108). If the closure member (106) is opened during operation, the detection switch (112) reverts to its default state and signals the control circuit (110) to immediately disable the radiation emission assembly (108). This operational arrangement prevents accidental radiation exposure to users and maintains compliance with safety guidelines for ultraviolet or other decontaminating radiation. The detection switch (112) may be mounted on a dedicated bracket or integrated within the housing of the closure member (106) or container body (102). Electrical connection from the detection switch (112) to the control circuit (110) is provided via insulated wiring or a flexible printed circuit. The detection switch (112) is calibrated to prevent false triggering from vibration or partial closure, ensuring only intentional and complete engagement of the closure member (106) activates the system (100).
[00051] The radiation-based decontamination apparatus (100) includes a power input interface (114) electrically linked to the control circuit (110), wherein the power input interface (114) is structured to receive electrical power from an external source. The power input interface (114) establishes the primary electrical connection between the apparatus (100) and an external power supply, which may include wall-mounted adapters, USB power ports, or battery packs. The power input interface (114) may be implemented as a USB Type-C port, micro-USB connector, barrel jack, or AC power inlet depending on the intended use environment and voltage requirements. The power input interface (114) may incorporate protective features such as reverse-polarity protection, surge protection, or overcurrent limiting components to safeguard internal circuitry. The incoming power is directed to the control circuit (110), which regulates and distributes power to the radiation emission assembly (108) and auxiliary components such as indicators, sensors, and switches. In some embodiments, the power input interface (114) may be accompanied by a power switch or input detection sensor to activate system readiness. The power input interface (114) may be mechanically reinforced within the container body (102) to prevent detachment or internal strain due to repeated insertion and removal of connectors. The voltage and current ratings of the power input interface (114) are selected based on the operational demands of the radiation emission assembly (108), ensuring stable energy delivery throughout a complete sterilization cycle. In certain configurations, the power input interface (114) may also support recharging of an internal battery if the apparatus (100) is designed for portable operation. Electrical pathways from the power input interface (114) to the control circuit (110) are implemented through printed circuit board traces or insulated wiring, forming a secure and reliable energy conduit necessary for the functioning of the radiation-based decontamination apparatus (100).
[00052] In an embodiment, the container body (102) comprises a reflective inner surface arranged to redistribute decontaminating radiation toward multiple orientations of at least one item positioned within the internal cavity (104). The reflective inner surface may include a metallic coating, reflective polymer film, or vapor-deposited layer applied to one or more inner walls of the container body (102). Examples of reflective materials include aluminium, silver, or white PTFE-based coatings. The reflective inner surface enhances uniform exposure by redirecting radiation emitted by the radiation emission assembly (108) into regions not directly facing the emitters. This arrangement increases overall radiation distribution and enables coverage of curved or recessed object geometries. The reflective inner surface may be formed as a continuous coating or discrete panels adhered to structural surfaces within the internal cavity (104). The reflectivity may be tuned based on the operating wavelength of the radiation emission assembly (108). The reflective inner surface may additionally exhibit resistance to ultraviolet-induced degradation, chemical exposure, and mechanical wear. The reflective surface may be shaped to conform to the structural features of the internal cavity (104), maintaining compatibility with object placement and tray alignment. The presence of the reflective inner surface reduces localized radiation intensity variations and promotes efficient decontamination of the object placed within the apparatus (100).
[00053] In an embodiment, the radiation emission assembly (108) comprises a plurality of light-emitting elements mounted on at least two opposing interior surfaces of the internal cavity (104). The plurality of light-emitting elements may include ultraviolet-C light-emitting diodes arranged in linear or matrix configurations on the upper and lower surfaces or opposing sidewalls of the internal cavity (104). The emitters may be positioned to create overlapping radiation fields, ensuring consistent exposure across the entirety of the object’s surfaces. Mounting of the light-emitting elements may be achieved through soldered joints on circuit boards, adhesive bonding, or mechanical retention within formed recesses. The opposing placement of light-emitting elements reduces the likelihood of radiation shadows and improves penetration into structural recesses such as hinges or frame contours. The electrical interconnections for the light-emitting elements may run along cavity walls or be integrated into flexible printed circuit substrates. Additional components such as reflectors, beam shaping optics, or protective shields may be co-located with the emitters to control directionality and prevent user exposure. The distributed configuration of light-emitting elements facilitates three-dimensional coverage and increases the microbial inactivation rate. The number and spacing of the emitters may be selected based on the expected size and shape of items positioned within the internal cavity (104) of the apparatus (100).
[00054] In an embodiment, a removable support tray is positioned within the internal cavity (104), and the removable support tray is formed of a non-abrasive material. The removable support tray provides a designated surface for holding the item during the sterilization process, ensuring stability and consistent radiation exposure from multiple angles. The removable support tray may be constructed from silicone rubber, thermoplastic elastomers, or foam-based composite materials selected for their non-reactive and soft-contact characteristics. The support tray may be dimensioned to match the contour or general profile of optical devices, such as spectacles, to prevent movement during operation. The tray may include slots, grooves, or ridges to secure the item in a defined orientation within the internal cavity (104). The material of the tray is selected to avoid scratching or wearing down coatings applied to the item’s surface, including anti-reflective or photochromic lens coatings. The removable support tray may be detachable for cleaning, replacement, or repositioning depending on object size or sterilization requirements. Structural design of the removable support tray may allow unrestricted passage of radiation between light-emitting elements and the object’s surface. The removable support tray supports repeatable placement and may include integrated alignment features compatible with the cavity shape of the container body (102).
[00055] In an embodiment, the internal cavity (104) is formed with a sealed geometry to prevent radiation leakage during operation. The sealed geometry is established through mating surfaces between the container body (102) and the closure member (106), including overlaps, compression features, or interlocking contours. Seal integrity is maintained to ensure that ultraviolet radiation emitted by the radiation emission assembly (108) remains contained within the internal cavity (104) and does not escape into the surrounding environment. Gasket materials, such as UV-resistant silicone strips or foam linings, may be installed along the closure interface to fill gaps and maintain consistent sealing pressure. The sealed geometry may include stepped interfaces, flanges, or tongue-and-groove joints to maintain alignment and reduce angular displacement between components. The sealed geometry may be verified through testing procedures, including light leakage detection or pressure decay testing. The structural integration of the sealed geometry contributes to the safe usage of the apparatus (100) in domestic or clinical environments. Materials forming the internal cavity (104) and surrounding enclosures are selected to maintain structural rigidity under repeated loading and to resist dimensional changes caused by temperature fluctuations or repeated exposure to ultraviolet radiation.
[00056] In an embodiment, the radiation emission assembly (108) emits radiation in a wavelength range from 265 nanometers to 280 nanometers. Emission in this wavelength range is selected for its high germicidal efficiency and is effective in deactivating a broad range of bacteria, viruses, and fungi. The radiation may be generated by ultraviolet-C light-emitting diodes specifically rated for this emission band. Alternative emitter types such as mercury vapor discharge tubes or excimer-based sources may also be employed, provided they deliver output within the specified wavelength range. Radiation at wavelengths between 265 nanometers and 280 nanometers penetrates microbial cell walls and induces dimerization of nucleic acids, thereby inhibiting replication and viability. Emission characteristics are verified using radiometric equipment during calibration and may be maintained over operational life using feedback circuitry within the control circuit (110). The radiation emission assembly (108) is arranged to deliver uniform spectral output across its emission surfaces, ensuring that all accessible regions of the item receive adequate radiation dose. Optical filters or bandpass elements may be incorporated into the emission assembly to narrow or refine the emitted spectrum. Material selection for components within the internal cavity (104) accounts for reflectivity and stability at the target wavelength range.
[00057] In an embodiment, the internal cavity (104) is dimensioned to accommodate optical devices selected from a group consisting of spectacles, sunglasses, and reading glasses. The internal cavity (104) may be shaped and sized to fit the typical form factors of eyewear products, with adequate clearance to avoid contact between the item and cavity walls during loading and operation. The cavity length, width, and height may be based on statistical measurements of consumer eyewear dimensions, including frame width, temple length, and lens curvature. The cavity is also structured to permit access by radiation emitted from multiple directions, enabling exposure to upper, lower, and lateral surfaces of the optical device. Interior spacing may allow for the positioning of the optical device on a removable support tray without compromising exposure paths. The cavity’s geometric constraints account for both rigid and foldable frames and may include adaptive design elements for accommodating variable sizes. Materials forming the cavity interior are selected for compatibility with optical coatings and to avoid chemical interactions with lens treatments. The cavity configuration supports secure placement of eyewear, minimizing movement during operation and maintaining exposure consistency throughout the sterilization cycle performed by the apparatus (100).
[00058] In an embodiment, the internal cavity (104) is shaped to accommodate geometrical features of optical accessories including nose bridges, temple hinges, and lens rims. Such shaping enables directional exposure of radiation onto recessed, angular, or curved regions of the optical device that are prone to reduced coverage in standard flat-cavity designs. The shaping may include molded recesses, elevation changes, or internal ribs that follow the natural contours of the eyewear components. The purpose of the shaping is to eliminate radiation shadow zones by facilitating multidirectional access from the radiation emission assembly (108). Spatial allowances are included for high curvature lenses, raised nose pads, and folding temple arms. The cavity shape may be symmetric or asymmetric, based on target device orientation. Features incorporated into the cavity may support consistent placement of optical accessories while preventing over-compression or distortion of the frame. Internal shaping may also assist with passive reflection of emitted radiation into hard-to-reach areas. The internal cavity (104) design is based on ergonomic and dimensional studies of optical products, and such shaping supports complete exposure of areas typically shielded in non-tailored sterilization devices.
[00059] In an embodiment, the control circuit (110) is structured to disable the radiation emission assembly (108) upon detection of partial movement of the closure member (106) after initiation of a sterilization cycle. The control circuit (110) receives real-time input from the detection switch (112), which monitors the closure member (106) position. Upon initiation of a sterilization cycle, a signal confirming full closure is required to enable the radiation emission assembly (108). If any displacement or unseating of the closure member (106) occurs during the active cycle—such as opening by the user or mechanical disruption—the detection switch (112) transitions to an open state. This transition is interpreted by the control circuit (110) as a breach of the sealed condition, triggering an immediate shutdown of the radiation emission assembly (108). The control logic implemented in the control circuit (110) includes interrupt routines or comparator logic that responds within milliseconds to state changes from the detection switch (112). The disabling mechanism is designed to prevent radiation leakage and ensure user safety by restricting operation to fully enclosed conditions only. Visual or audible indicators may be activated simultaneously to notify the user that the sterilization cycle was interrupted and must be restarted following secure reclosing of the closure member (106).
[00060] In an embodiment, a passive ultraviolet intensity equalizer is disposed within the internal cavity (104), and the equalizer is structured to suppress non-uniform beam convergence from opposing light sources in the radiation emission assembly (108). The passive ultraviolet intensity equalizer may include components such as diffusing screens, translucent plates, or textured reflective panels positioned to interrupt and redistribute radiation emitted from directly aligned emitters. The equalizer may be placed between upper and lower emitter arrays or along sidewalls where intensity gradients are observed. Materials used for the equalizer may include UV-transmissive polymers, etched quartz, or diffusive ceramic plates designed to maintain spectral integrity while altering spatial distribution. The shape, size, and placement of the equalizer are determined based on cavity dimensions, emitter orientation, and desired exposure uniformity. The equalizer functions without active electronics and introduces no external power demand. Installation may involve mechanical clips, slots, or adhesive bonding. Use of the equalizer reduces the risk of overexposure in focal zones and improves the homogeneity of radiation intensity across the item surface. The passive ultraviolet intensity equalizer contributes to consistent microbial reduction results by minimizing localized under- or overexposure across geometrically complex or asymmetrically placed items within the internal cavity (104).
[00061] In an embodiment, container body (102) defines internal cavity (104), which enables controlled enclosure of at least one item for exposure to decontaminating radiation. Said configuration permits isolation of the target item from external environmental variables such as ambient light, dust, or contaminants, which could otherwise interfere with the sterilization process. The defined internal cavity (104) restricts the radiation path to a confined space, allowing consistent dosage delivery and enhancing microbial inactivation reliability. Structurally, container body (102) provides positional support for internal components, including radiation emission assembly (108), closure member (106), and detection switch (112), allowing precise alignment and operational coordination during a sterilization cycle. The structural rigidity and optical resistance of container body (102) further contribute to radiation containment, safety, and repeatable performance under cyclical operation.
[00062] In an embodiment, closure member (106) is movable between an open position and a closed position for enclosing internal cavity (104), and said motion directly governs activation states of control circuit (110) via detection switch (112). The operability of closure member (106) allows for secure loading and unloading of the item without disrupting internal configurations. Upon full closure, internal cavity (104) forms a sealed region, thereby eliminating opportunities for external light interference or radiation escape. Said enclosure contributes to user safety by preventing unintentional exposure to active radiation. The functional association of closure member (106) with detection switch (112) establishes a conditional logic that restricts system activation to safe configurations only, further reducing potential health hazards due to improper operation or early lid disengagement.
[00063] In an embodiment, radiation emission assembly (108) is disposed within internal cavity (104) and is arranged to emit decontaminating radiation directly toward surfaces of the item positioned therein. Placement of radiation emission assembly (108) within internal cavity (104) minimizes loss of radiation energy and enables closer proximity to the item, allowing for more efficient irradiation and greater surface coverage. Said internal positioning removes the need for external exposure paths, thereby simplifying enclosure design and improving energy conversion efficiency. The positioning also allows flexible emitter configurations, including top-down, bottom-up, or lateral orientations for better penetration into geometrically complex item surfaces. Radiation delivery is consistent, controlled, and spatially optimized, allowing the apparatus (100) to achieve improved microbial load reduction over conventional external-light systems.
[00064] In an embodiment, control circuit (110) is electrically connected to radiation emission assembly (108) and arranged to manage the operational cycle. Said connection enables dynamic activation and timed deactivation based on predefined parameters. Control circuit (110) introduces autonomous regulation of the radiation output, thereby reducing dependency on manual intervention and ensuring standardization across cycles. Predefined cycle execution results in reliable radiation dosage delivery and minimizes under- or over-exposure, improving safety and performance consistency. The integration of electrical logic with emitter regulation allows immediate cessation of operation in response to fault signals or interruption conditions detected by detection switch (112), thereby preventing unintended irradiation events.
[00065] In an embodiment, detection switch (112) is positioned adjacent to closure member (106) and enables control circuit (110) only when closure member (106) is detected in the closed position. Said position-dependent functionality introduces a safeguard that directly links mechanical enclosure to electrical activation. The positional dependency ensures that radiation emission assembly (108) remains inactive unless closure member (106) has achieved full mechanical engagement, thereby preventing radiation leakage and unsafe operating conditions. The positional interaction between detection switch (112) and closure member (106) also enables immediate response to tampering, mid-cycle opening, or incomplete enclosure, enabling automatic interruption of the sterilization process and maintaining safety standards.
[00066] In an embodiment, power input interface (114) is electrically linked to control circuit (110) and structured to receive electrical power from an external source. Said configuration allows compatibility with standardized power supplies such as USB power adapters or direct current battery banks, facilitating versatile deployment of apparatus (100) across multiple environments. The fixed positioning of power input interface (114) external to container body (102) simplifies user access while maintaining insulation from internal components. Electrical stability provided by power input interface (114) directly contributes to consistent functioning of control circuit (110) and radiation emission assembly (108), which depend on regulated voltage levels for operation.
[00067] In an embodiment, container body (102) comprises a reflective inner surface arranged to redistribute decontaminating radiation toward multiple orientations of at least one item. Said reflective inner surface compensates for shadow zones and object surface occlusions by reflecting incident radiation toward previously unexposed surfaces. The positional effect of radiation bounce increases coverage without requiring additional emitters. Reflective properties of said surface enhance internal radiation utilization, resulting in greater energy efficiency and improved sterilization uniformity. Said reflective surface also reduces the risk of overexposure in directly irradiated zones by distributing energy across the internal cavity (104), thereby balancing total dose received across the item.
[00068] In an embodiment, radiation emission assembly (108) comprises a plurality of light-emitting elements mounted on at least two opposing interior surfaces of internal cavity (104). Said opposing positioning creates intersecting radiation paths that enhance surface irradiation from multiple directions. Said arrangement minimizes dead zones caused by geometry-induced occlusions such as lens curvature, frame hinges, or recessed crevices. The bidirectional exposure facilitated by opposing surface emitters reduces dependency on object orientation and improves reproducibility of decontamination cycles. The spatial configuration also enables reduced emitter power per unit while maintaining effective dosage due to overlapping field intensities, thereby optimizing component lifespan and power consumption.
[00069] In an embodiment, a removable support tray is positioned within internal cavity (104), and said support tray is formed of a non-abrasive material. Said positioning stabilizes the object during operation and prevents contact with structural walls or light emitters, which may affect exposure uniformity or damage object surfaces. The material properties of the support tray avoid scratching or degrading sensitive coatings on optical items. The removable nature allows easy replacement and cleaning, promoting hygienic reuse and operational flexibility. The alignment between the tray’s support surface and the emission path of radiation emission assembly (108) ensures consistent exposure regardless of item placement variability, resulting in reduced sterilization variability across use cycles.
[00070] In an embodiment, internal cavity (104) is formed with a sealed geometry to prevent radiation leakage during operation. Said geometry ensures that all radiation remains confined within container body (102), eliminating hazards associated with user exposure to ultraviolet radiation. Positional interfacing between sealing surfaces of closure member (106) and container body (102) maintains structural contact and optical insulation throughout operational cycles. Such positional sealing contributes to device safety certification compliance and allows use in residential or clinical environments. The sealed geometry also maintains internal radiation concentration, which increases decontamination efficiency by minimizing radiation dissipation and uncontrolled escape from intended exposure zones.
[00071] In an embodiment, radiation emission assembly (108) emits radiation in a wavelength range from 265 nanometers to 280 nanometers. Said spectral band corresponds to maximum germicidal activity with minimal risk of ozone production, thereby improving microbial inactivation performance. The wavelength-specific emission ensures disruption of DNA and RNA of bacteria, viruses, and fungi, reducing colony-forming unit counts with shorter exposure times. The narrow wavelength band reduces unnecessary irradiation outside effective microbial absorption peaks, preserving object integrity and reducing cumulative energy input. Spectral accuracy of radiation emission improves sterilization reliability across multiple usage cycles, even with variation in object geometry and surface reflectivity.
[00072] In an embodiment, internal cavity (104) is dimensioned to accommodate optical devices selected from a group consisting of spectacles, sunglasses, and reading glasses. The dimensional matching between internal cavity (104) and typical eyewear profiles enables secure, repeatable placement, improving radiation targeting accuracy. The positional confinement avoids unnecessary rotation or displacement during operation, which can result in exposure gaps or uneven dosage distribution. Said dimensional adaptation also minimizes wasted cavity volume, improving radiation field concentration and energy usage per unit volume, which contributes to faster cycle times and consistent microbial reduction across a wide range of frame types.
[00073] In an embodiment, internal cavity (104) is shaped to accommodate geometrical features of optical accessories including nose bridges, temple hinges, and lens rims. Said shaping enhances direct and reflected radiation delivery into recessed or angular surface regions that typically remain shielded in flat or unshaped cavities. The positional adaptation of internal contours supports spatial exposure uniformity by eliminating occluded zones. Said feature enables enhanced microbial contact surface coverage, particularly in high-contact zones of eyewear associated with skin and mucosal proximity. The shape-specific exposure paths reduce the need for manual repositioning or tray adjustments, simplifying operation and improving cycle-to-cycle reproducibility.
[00074] In an embodiment, control circuit (110) is structured to disable radiation emission assembly (108) upon detection of partial movement of closure member (106) after initiation of a sterilization cycle. Said structural configuration introduces dynamic monitoring of positional integrity between closure member (106) and container body (102). The response to partial movement, including minor lifting or shifting, provides real-time safety assurance and radiation cutoff. Said positional safety control prevents mid-cycle exposure events due to accidental disturbance or unauthorized access. The circuit logic supporting this effect allows conditional execution and interruption of radiation emission based solely on positional state change, further reinforcing system safety.
[00075] In an embodiment, a passive ultraviolet intensity equalizer is disposed within internal cavity (104), and said equalizer is structured to suppress non-uniform beam convergence from opposing light sources in radiation emission assembly (108). The positional placement of the equalizer, typically between converging emitter fields, redistributes local energy concentrations and minimizes overexposure in central regions. The equalizer diffuses radiation into underexposed zones without requiring active modulation, balancing intensity gradients across object surfaces. This positional redistribution improves sterilization uniformity, particularly in high-density emitter configurations, where beam convergence may otherwise cause hotspot formation or partial shielding artifacts on complex object geometries.
[00076] In an embodiment, the control circuit (110) is programmed to operate the radiation emission assembly (108) for a sterilization cycle having a duration of more than ten minutes. Said control circuit (110) is arranged to receive input from the detection switch (112) and initiate the predefined cycle only upon confirmation of the closed state of the closure member (106). Upon completion of the sterilization cycle, the control circuit (110) disables the radiation emission assembly (108) automatically. The timed operation enables standardized exposure intervals for consistent microbial inactivation across multiple use instances.
[00077] In an embodiment, the radiation-based decontamination apparatus (100) is experimentally validated for microbial reduction against Escherichia coli (E.coli), wherein such validation confirms that more than 99.9% of colony-forming units are eliminated upon continuous exposure to radiation emitted by the radiation emission assembly (108) within the internal cavity (104) for more than ten minutes. Said microbial reduction is achieved without the use of chemicals, heat, or physical abrasion, preserving the structural and optical integrity of the object placed within the apparatus (100).
[00078] In an embodiment, the radiation emission assembly (108) comprises a removable and replaceable emitter board or light-emitting structure, enabling maintenance or upgrade without replacing the entire apparatus (100). Said removable emitter arrangement allows the user to detach the radiation emission assembly (108) from its position within the internal cavity (104) for serviceability or technology enhancement, while retaining electrical linkage to the control circuit (110).
[00079] In an embodiment, the power input interface (114) is electrically linked to both the control circuit (110) and an internal power storage device, such as a rechargeable battery. Said configuration enables dual-mode operation of the apparatus (100) using either external power via a USB Type-C input or internal power supplied by the rechargeable battery. The apparatus (100) may be used in mobile, home, or field settings without dependence on continuous connection to an external power source.
[00080] In an embodiment, the internal cavity (104) of the container body (102) includes integrally formed contours or soft supports arranged to accommodate structural features of optical accessories such as nose bridges, temple arms, and lens edges. Said contouring maintains the position of the item within the internal cavity (104) during operation and enables consistent directional exposure from the radiation emission assembly (108), while minimizing the risk of displacement or misalignment.
[00081] In an embodiment, the control circuit (110) includes an overexposure protection system arranged to automatically disable the radiation emission assembly (108) upon detecting that operational duration has exceeded a maximum threshold beyond the predefined cycle. Said overexposure prevention protects the optical properties of sensitive lens materials and prolongs emitter life by avoiding excessive radiation delivery.
[00082] In an embodiment, the container body (102) and the internal cavity (104) are constructed from polymeric materials selected for compatibility with optical devices comprising anti-reflective coatings, photochromic surfaces, or tinted lenses. Said materials resist chemical interaction, thermal deformation, and photodegradation during repeated sterilization cycles, preserving the physical and visual characteristics of the items placed within the apparatus (100).
[00083] In an embodiment, the apparatus (100) is structured for non-contact sterilization, wherein the object placed within the internal cavity (104) is subjected solely to radiation emitted by the radiation emission assembly (108), without application of liquid, chemical, or mechanical cleaning agents. Said contactless approach prevents abrasion, smudging, or alteration of surface coatings on the item, and provides residue-free decontamination suitable for repeated daily use.
[00084] FIG. 2 illustrates a process flow representing the operational structure of a radiation-based decontamination apparatus (100), in accordance with the embodiments of the present disclosure. An external power source is electrically connected to a power input interface (114), which supplies regulated electrical energy to a control circuit (110). Simultaneously, a closure member (106) is operatively engaged with a detection switch (112), which detects the positional state of the closure member (106) and transmits a corresponding signal to the control circuit (110). Upon confirmation of both power availability and full closure detection, the control circuit (110) activates a radiation emission assembly (108). Said radiation emission assembly (108) emits decontaminating radiation within a controlled exposure band toward surfaces located inside an internal cavity (104). The internal cavity (104) is defined within a container body (102), and said cavity houses at least one item for decontamination. The radiation emitted by the radiation emission assembly (108) irradiates all accessible surfaces of the item for decontamination, achieving microbial inactivation. The container body (102) structurally supports all components and ensures safe containment of radiation during operation.
[00085] FIG. 3 illustrates a process sequence for operating a radiation-based decontamination apparatus (100), in accordance with the embodiments of the present disclosure. The process begins with a user initiating the operation by placing spectacles or other optical accessories into the internal cavity of the apparatus (100). Once properly positioned, the user proceeds to close the lid, which serves as the closure member and forms a seal with the container body. The closing action of the lid mechanically engages a safety interlock mechanism, thereby triggering a detection switch that confirms the closure condition. Upon detection of a fully closed state, the control circuit activates a timing sequence and energizes the ultraviolet-C (UV-C) light-emitting diodes arranged within the cavity. The UV-C radiation is then emitted for a predefined cycle duration sufficient to deactivate microbial contaminants from exposed surfaces of the spectacles. During the cycle, the sealed geometry of the apparatus ensures no radiation leakage occurs, maintaining operational safety. After the cycle completes, the user is allowed to reopen the lid and retrieve the disinfected spectacles. This automated and sequenced process flow enables consistent and repeatable sterilization, minimising manual intervention and eliminating the need for chemical disinfectants or abrasive cleaning methods, thereby preserving the integrity of optical surfaces.
