DESC:FIELD OF THE INVENTION

The present disclosure relates to lighting devices, and more particularly to an elongated light emitting device capable of emitting diffused and uniform illumination from a cove, ledge, niche, or recess along the walls and ceilings.

BACKGROUND

Usually, cove lighting devices are used to project indirect light and are typically installed in ledges, niches, or recesses along the walls and ceilings, or any other architectural element to create a soft and diffused illumination.
Currently, existing cove lighting devices have inefficient heat dissipation mechanisms. As such, due to prolonged usage of the cove lighting devices, the components of the cove lighting devices are exposed to elevated temperatures which significantly impact the operational lifespan of the components. A reduced lifespan not only necessitates frequent replacements of the components but also increases maintenance efforts and costs. Further, an inability to effectively manage heat can result in thermal issues causing a decline in performance of the existing cove lighting devices. Performance degradation may result in reduced light output, altered colour rendering, compromised efficiency, and diminishing lighting quality over time. Hence, the existing cove lighting devices present the above-mentioned thermal challenges that pose substantial risks to both the functionality and the operational lifespan of the cove lighting devices.
Further, the existing cove light devices have various intricate components that are meticulously assembled and aligned together. Due to this, manufacturing and production of the existing cove light devices is a labour-intensive process that increases the overall costs and time involved. Due to the presence of a greater number of components in the existing devices, the potential points of failure within the device also increase. Additionally, maintenance of the existing cove lighting devices is also cumbersome, involving intricate disassembly to access and replace components within the device.

Therefore, there is a need for a solution to address the aforementioned issues and challenges.

Figure 1 illustrates a perspective view of an elongated light emitting device 100, according to an embodiment of the present disclosure. Figure 2 illustrates an exploded view of the elongated light emitting device 100, according to an embodiment of the present disclosure.

Referring to Figures 1 and 2, the elongated light emitting device 100 may have a heat dissipating frame 102, a light transmitting unit 104, and a housing 106. The heat dissipating frame 102 and the housing 106 may provide support and mount a light source (not shown) and one or more electrical components (not shown) respectively. The one or more electrical components may include, but are not limited to, a driver or a transformer to supply the required power to the light source. The heat dissipating frame 102 and the housing 106 may couple together and define an enclosure (shown in Figure 3) to place the one or more electrical components. The heat dissipating frame 102 may be made of a thermally conductive material. In one example, the heat dissipating frame 102 may be made of, but is not limited to, aluminium. The housing 106 may be made of a metal or a plastic having one or more grooves (not shown) enabling the housing 106 to fit into the heat dissipating frame 102.

In an embodiment, the light transmitting unit 104 may be made up of, but not limited to, a translucent or frosted material that covers the light source to diffuse and soften the light. The light transmitting unit 104 may aid in minimizing glare and creating uniform illumination. The type of material used to manufacture the light transmitting unit 104 may influence the quality and appearance of the light emitted.

In an embodiment, the elongated light emitting device 100 may have a pair of first end caps 108 and a pair of second end caps 110. The elongated light emitting device 100 may have the pair of first end caps 108 to securely fit the light transmitting unit 104 with the heat dissipating frame 102 and enclosing the light transmitting unit 104 from the ends. Similarly, the pair of second end caps 110 may aid in engaging the heat dissipating frame 102 with the housing 106 from the ends thereby forming a cohesive and enclosed structure. By securely capping the ends, the pair of first end caps 108 and the pair of second end caps 110 may prevent any potential damage or exposure of internal components such as the light source, wires, and one or more electrical components.

In one embodiment, the pair of first end caps 108 and the pair of second end caps 110 may have sealing mechanisms to enhance weatherproofing thereby preventing water ingress and protecting the internal components from environmental hazards. Further, the pair of first end caps 108 and the pair of second end caps 110 may contribute to the visual appeal of the elongated light emitting device 100, providing a finished and polished appearance to the ends of the elongated light emitting device 100. Also, the pair of first end caps 108 and the pair of second end caps 110 may simplify the installation process, thereby ensuring a snug fit. Additionally, if maintenance is required, the pair of first end caps 108 and the pair of second end caps 110 may be easily removed and reinstalled thereby allowing convenient access to the internal components.

Figure 3 illustrates a perspective view of the elongated light emitting device 100 depicting an engagement of the light transmitting unit 104 with the heat dissipating frame 102, according to an embodiment of the present disclosure. Figure 4 illustrates a perspective view of the heat dissipating frame 102 of the elongated light emitting device 100, according to an embodiment of the present disclosure. Figure 5 illustrates a front view of the heat dissipating frame 102, according to an embodiment of the present disclosure. Figure 6 illustrates a front view of the elongated light emitting device 100 depicting the engagement of the light transmitting unit 104 with the heat dissipating frame 102, according to an embodiment of the present disclosure. For the sake of brevity, Figures 3 to 6 are described together.

In an embodiment, the heat dissipating frame 102 may be manufactured using an extrusion process. The heat dissipating frame 102, being extruded, may have a uniform profile along a length. In one example, due to the extruded profile of the heat dissipating frame 102, the heat dissipating frame 102 may be customized to have additional features, such as grooves, channels, or heat sinks, to meet functional and aesthetic requirements of the elongated light emitting device 100. The extruded profile of the heat dissipating frame 102 may provide high structural integrity to the elongated light emitting device 100. Further, more surface area may be available for heat dissipation due to the extruded profile of the heat dissipating frame 102 which ensures that thermal energy may effectively be transferred away from the light source. Therefore, the extruded profile of the heat dissipating frame 102 may not only promote the longevity of the light source but also enhance reliability of the elongated light emitting device 100.

In an embodiment, the extruded profile of the heat dissipating frame 102 may make the elongated light emitting device 100 lightweight while maintaining strength. Since the heat dissipating frame 102 may be manufactured through the extrusion process, the features of the heat dissipating frame 102 forms an integrated structure that saves time and cost on the assembly and disassembly of the elongated light emitting device 100. Further, due to the extruded profile of the heat dissipating frame 102, the heat dissipating frame 102 may have uniform cross-sectional dimensions along the length thereby ensuring ease of assembly of the heat dissipating frame 102 with the light transmitting unit 104 and the housing 106 during the manufacturing process. In one example, the extruded profile of the heat dissipating frame 102 may include, but is not limited to, a base 402, a pair of L-shaped supporting plates 404, a pair of side walls 406, and a bracket 408.

In an embodiment, the heat dissipating frame 102 may have the base 402 adapted to mount the light source. The base 402 may have a pair of edges 410 on opposite sides. The base 402 may define a U-shaped profile where the pair of edges 410 may resemble arms of the letter “U”. The pair of edges 410 may securely hold the light source in place. The base 402 may have the bracket 408 protruding vertically downwards from a mid-portion of the base 402. The bracket 408 may be adapted to hold one or more wires and may therefore be used as a wire management mechanism. In an embodiment, the bracket 408 may be adapted to engage the pair of first end caps 108 or/and the pair of second end caps 110.

The heat dissipating frame 102 may also include the pair of L-shaped supporting plates 404 and the pair of side walls 406. The pair of L-shaped supporting plates 404 may be connected integrally and extend orthogonally from opposite sides of the base 402. The pair of side walls 406 may further be connected integrally to the pair of L-shaped supporting plates 404. Each side wall from the pair of side walls 406 may have a first plate 406a connected to the pair of L-shaped supporting plates 404 at a predetermined angle from a first end 412 of the first plate 406a. A second plate 406b may extend orthogonally from a second end 414 of the first plate 406a.

In an embodiment, the base 402, the pair of L-shaped supporting plates 404, and the pair of side walls 406 may define and promote a natural convection pathway to dissipate the heat away from the light source. By allowing air to circulate around the base 402, the pair of L-shaped supporting plates 404, and the pair of side walls 406, a process of heat dissipation may be further enhanced thereby contributing to a more efficient cooling within the elongated light emitting device 100. Consequently, the elongated light emitting device 100 may function on reduced operating temperatures due to the efficient cooling within the elongated light emitting device 100. The reduction in operating temperature not only prolongs the operational lifespan of the elongated light emitting device 100 but also ensures consistent and optimal performance over an extended period thereby enhancing the reliability and durability of the elongated light emitting device 100.

In an embodiment, the light transmitting unit 104 may be adapted to transmit light from the light source. The light transmitting unit 104 may be of semi-circular shape. The semi-circular shape of the light transmitting unit 104 surrounds the light source thereby acting as an enclosure for the light source, also directing and channeling emitted light from the light source in a desired manner. At least a portion of the light transmitting unit 104 may be engaged with the pair of L-shaped supporting plates 404. In one example, a pair of ends 602 of the light transmitting unit 104 may be engaged within the pair of L-shaped supporting plates 404. The pair of ends 602 may have a curved profile to securely fit into the pair of L-shaped supporting plates 404. The pair of L-shaped supporting plates 404 may be an integral part of the heat dissipating frame 102, hence the light transmitting unit 104 may be securely attached to the pair of L-shaped supporting plates 404 as there are no moving member in the heat dissipating frame 102. Further, the housing 106 may be coupled to the heat dissipating frame 102 defining an enclosure 302 to place one or more electrical components.

The elongated light emitting device 100 as disclosed in the present invention may provide a cost-effective solution for dissipating the heat away from the light source. The provision of the base 402, the pair of L-shaped supporting plates 404, and the pair of side walls 406, made of the thermally conductive material ensures the heat from the light source is effectively dissipated away from the light source. The heat dissipation is increased due to the increased surface area of the heat dissipating components such as the base 402, the pair of L-shaped supporting plates 404, and the pair of side walls 406. Moreover, the use of the thermally conductive material and the increased surface area prevents overheating of the elongated light emitting device 100 and extends the operational lifespan of the internal components. In other words, improved thermal management contributes to a more stable and robust lighting solution thereby reducing the likelihood of performance degradation or premature component failure.

Advantageously, the use of the heat dissipating frame 102 having the extruded profile may contribute to low material costs. The extrusion process ensures that raw material may be efficiently utilized thereby minimizing waste which in turn, translates to low production costs and resulting in a lightweight assembly. The reduction in weight of the light emitting device 100 may may provide additional benefits, in terms of transportation, installation, and handling. The efficient use of materials and the resulting cost savings make the elongated light emitting device 100 more sustainable and economically feasible lighting solution. Furthermore, due to the extruded profile of the heat dissipating frame 102, the elongated light emitting device 100 may have inbuilt design features. The heat dissipating frame 102 have no moving parts thereby contributing to the stability of the elongated light emitting device 100, further minimizing the risk of malfunctions and wear and tear caused over time.

The drawings and the forgoing description give examples of embodiments.
