DESC:A LIGHTING DEVICE

TECHNICAL FIELD
[0001] The present disclosure, in general, relates to a lighting device. The present disclosure, particularly, relates to a lighting device capable of concealing lighting device holder in assembled state.

BACKGROUND
[0002] Generally lighting devices, such as LED bulbs, are available in the market which are used domestically. The existing assembly of lighting devices usually have two components i.e. a lighting device and a lighting device holder. The lighting device holder is permanently fixed on the desired location where lighting device is required. In other embodiments, the lighting device holder is suspended from a height through a wire. The lighting device is later on detachably attached with the lighting device holder.
[0003] The lighting device holder is connected to the power source though wire. In the suspended state, the wires are exposed which is dangerous. In the permanently fixed state, the lighting device holder is permanently fixed on the wall and the lighting device is detachably attached to the lighting device holder. To replace the faulty lighting device, the lighting device is detached from the lighting device holder and new lighting device is detachably attached.
[0004] The lighting device holder is capable of detachably mounting different types of lighting devices.
[0005] Referring to Figure 1 illustrating a lighting device holder as per the existing art. The lighting device holder 100 is preferably of B22 configuration which is widely used. The lighting device holder 100 comprises a base 101, a socket 102 and a socket cover 103. The base 101 is adapted to fixedly mount on the wall at desired location. The base 101 is provided with plurality of holes 104 to accommodate fasteners to facilitate fixing of the lighting device holder. The base 101 has a cavity to accommodate a socket 102. Front end of the socket 102 is designed to accommodate conducting base of the lighting device. The socket 102 has pogo-pin assembly 102a to create a connection with the lighting device. In addition, the socket 102 has slots 102b provided on the outer periphery to engage with the lighting device. The socket 102 is further connected with power supply. The socket cover 103 surrounds the socket 102 in all directions. The socket cover 103 is fixedly attached to the base 101 of the lighting device holder 100. In assembled condition, the lighting device holder 100 act as a unitary device with all the body parts fixedly attached.
[0006] Referring to Figure 2 illustrating a lighting device as per the existing art. The lighting device 200 comprises a diffuser 201, a circuitry housing 202, an LED bulb circuitry, a printed circuit board and a conducting base 203. The diffuser 201 and the circuitry housing 202 is adapted to detachably or non-detachably connect with each other creating an inner hollow space. The diffuser 201 and the circuitry housing 202 could have different structural configurations resulting in different types of lighting devices. However, the existing lighting devices 200 exposes the lighting device holder 100 in assembled state. The inner hollow space is capable of accommodating LED bulb circuitry and printed circuit board. The diffuser 201 is capable of diffusing the light generated by the LED bulb circuitry. The conducting base 203 is fixedly attached to the circuitry housing 202. In an aspect, the conducting base 203 is in a B22 holder configuration capable of creating a connection with the socket part 102 of the lighting device holder 100.
[0007] In the existing art, the lighting devices could have different structural aspects. Sometimes, these structural aspects do not complement with the lighting device holder 100 which is already mounted on the wall. The socket covering part 103 of the lighting device holder 100 may not properly conceal the conducting base 203 part of the lighting device 100. This creates safety hazard during replacement of the lighting device 100 as the conducting base part 203 is exposed. Further, the slot on the socket 102 may not perfectly align with the central axis of the lighting device holder 100. Furthermore, the plurality of holes 104 on the lighting device holder 100 may misalign with the ceiling line or wall line. These drawbacks create possibility of electric shocks which is a safety hazard. Further, the exposed conducting base 203 and misalignment of the lighting device holder 100 is not aesthetically desirable.
[0008] Accordingly, there is a need for a lighting device that conceal the lighting device holder while being adaptable to various types of lighting device holder.

[0035] In order to rectify this safety concern and mitigate the risk of accidental electric shock, it is necessary to improve the existing lighting devices.
[0036] To solve this problem, a lighting device is required with improved design.
[0037] The present disclosure provides a lighting device capable of concealing the lighting device holder. While discussing FIG. 3 below, it is assumed that the lighting device holder is compatible with the lighting device.
[0038] FIG. 3 illustrates an exemplary lighting device that can be utilized to implement one or more exemplary embodiments of the present disclosure. The lighting device 300 comprises a diffuser 301, a circuitry housing 302, an LED bulb with circuitry, a printed circuit board 303 and a conducting base 304.
[0039] The diffuser 301 is adapted to evenly diffuse the lights emitted from the LED bulb. The diffuser 301 is either fixedly or detachably attached to the circuitry housing 302. In an aspect, the diffuser 301 has a dome shaped structure with a flattened top. Bottom of the diffuser 301 is capable of attaching to top of the circuitry housing 302. In an aspect, the circuitry housing 302 has a hollow bowl shaped structure with an outer portion 302a and an inner portion 302b. The outer portion 302a altogether form outer surface of the circuitry housing 302. The inner portion 302b integrally extending inwardly from bottom edge of the outer portion 302a of the circuitry housing 302. The inner portion 302b has a first angular portion 302c, a second horizontal portion 302d and a third vertical portion 302e. The first angular portion 302c integrally extending inwardly from bottom edge of the outer portion 302a of the circuitry housing 302. The second horizontal portion 302d extends horizontally from the top end of the first angular portion 302c. The third vertical portion 302e extends vertically downwards from the second horizontal portion 302d. The second horizontal portion 302d of the circuitry housing 302 act as a base to provide support to the LED with circuitry and printed circuit board 303. The third vertical portion 302e of the inner portion 302b of the circuitry housing 302 creates a hole 305 in the middle. In addition, the first angular portion 302c of the inner portion 302b of the circuitry housing 302 creates a cavity in the middle to envelope the lighting device holder 306.
[0040] The hole 305 in the middle of the circuitry housing 302 is adapted to accommodate the conducting base 304. The conducting base 304 is electrically connected to the LED circuitry and Printed Circuit Board 303. The conducting base 304 is adapted to engage with the socket of the lighting device holder 306.
[0041] Since the circuitry housing 302 of the lighting device 300 is capable of enveloping the lighting device holder 306, the lighting device 300 completely eliminates safety hazard of accidental shock and also provide an aesthetic alternative to the crude looking exposed lighting holder devices.
[0042] FIG. 4 illustrates the lighting device in assembled state with the lighting device holder that can be utilized to implement one or more exemplary embodiments of the present disclosure. It could be easily understood from the illustrations that the lighting device is capable of covering the lighting device holder of various types completely. Further, in an aspect, the lighting device is capable of enveloping the lighting device holder with angular configuration.
[0043] FIG. 5 illustrates an exemplary lighting device that can be utilized to implement one or more exemplary embodiments of the present disclosure. While discussing the second embodiment of the lighting device, it is assumed that the lighting device holder is not compatible with the lighting device. To make the non-compatible lighting device compatible, a helical cut base 500 with helical slots 602 is additionally introduced in the lighting device 300. In addition, ridges 601 are provided in the helical slots 602 of the helical cut base 500. Further, plurality of pins (not shown) are provided near top end of the hole 305 in the circuitry housing 302. The helical cut base 500 has a cylindrical profile identical to the profile of the conducting base 304. In assembled state, the conducting base 304 is crimped/ attached to the helical cut base 500 which in turn engages with the pins provided on the hole 305 of the circuitry housing 302, thereby allowing relative motion between the circuitry housing 302 and the conducting base 304.
[0044] FIG. 6 illustrates the helical cut base that can be utilized to implement one or more exemplary embodiments of the present disclosure. The helical cut base 500 has a cylindrical profile with ridges 601 for locking. The ridges 601 are provided at an angle over the helical cut base 500.
[0045] FIG. 7 illustrates sectional view of the exemplary lighting device that can be utilized to implement one or more exemplary embodiments of the present disclosure. The pins 701 engages with the helical slots 602 on the helical cut base 500. The pins 701 are free to move in the helical slot 602. The ridges 601 gets flexed as the pin 701 passes through it for locking. The pins 701 move pass the ridges 601 thereby locking the pins 701. Movement of the pins 701 in the helical slots 602 results in relative rotational movement between the circuitry housing 302 and the conducting base 304.
[0046] FIG. 8 illustrates an exemplary lighting device in assembled state that can be utilized to implement one or more exemplary embodiments of the present disclosure. The helical cut base facilitates relative rotational motion between the lighting device holder and the lighting device thereby allowing position adjustment in case of non-compatibility of the lighting device with the lighting device holder.
