DESC:FIELD OF THE INVENTION

The present disclosure relates to a lighting apparatus and mounting of auxiliary devices thereon.

BACKGROUND

Light emitting diode (LED) is a semiconductor device that emits light when electric current is supplied to it. LEDs have higher electrical efficiency over fluorescent light or incandescent light sources and thus are preferrable choice in making lighting devices, such as light bulbs or batons. Such LED lighting devices are square shaped or rectangular shaped panels that are installed on the ceiling. Further, the wires and the driver are mounted on the back of the panel and the wires are secured to the back of the panel.

There are various limitations associated with the current design of the lighting devices. For instance, such panels may not be able to align the LED in such a way that the panels are able to illuminate the space homogenously. Moreover, since the panel is a closed unit, the heat generated by the LEDs is not dissipated, thereby causing damage to the LED and reducing the operational life of the panel.

SUMMARY

This summary is provided to introduce a selection of concepts, in a simplified format, that are further described in the detailed description of the invention. This summary is neither intended to identify key or essential inventive concepts of the invention and nor is it intended for determining the scope of the invention.

The present disclosure relates to a lighting apparatus and a housing therein. The housing allows the mounting of auxiliary devices on the lighting apparatus while preventing tangling of wires.

In an embodiment, a lighting apparatus is disclosed that includes a housing which has a first support and a second support, each including a first articulated section and a second articulated section, respectively. The lighting apparatus includes a first guide plate having a vertical section coupled to the first support of the housing and a horizontal section adapted to mount a first guiding portion thereon. In addition, the lighting apparatus includes a second guide plate having a vertical section coupled to the second support of the housing and a horizontal section adapted to mount a second guiding portion thereon.

According to the present disclosure, the first guide plate and the second light guide plate ensure that the light guiding portions are coplanar that ensures homogenous light dispersion by the lighting apparatus. Moreover, the first guide plate 108 and the second light guide plate enable better heat dissipation from the light source, thereby ensuring longer operational life of the light source.

Figure 1 illustrates a schematic view of a lighting apparatus 100, according to an embodiment of the present disclosure. Specifically, Figure 1(A) illustrates a schematic bottom view of the light apparatus 100 while Figure 1(B) illustrates a schematic side view of the lighting apparatus 100. Further, Figure 1(C) illustrates a schematic top view of the light apparatus 100. The lighting apparatus 100 may be employed to provide illumination in a space. The lighting apparatus 100 can be mounted on a ceiling in such a way that the lighting apparatus 100 may be suspended from the ceiling using a pair of strings 102 that are coupled to a pair of locking mechanisms 104 on the lighting apparatus 100.

Referring now to Figure 2 which illustrates a cross-section of the lighting apparatus 100 taken along lines 1-1 of Figure 1. The lighting apparatus 100 is formed of a housing 106 that forms a major body of the lighting apparatus 100. The housing 106 may be made of either a polymer or a metal/alloy. The housing 106 may be configured to perform two tasks. First, the housing 106 may be configured to support a first guiding plate 108 and a second guiding plate 110 thereon. The housing 106 may include a first support 112 and a second support 114, and a top support 116.

Referring now to Figure 3 that shows the first support 112 and the second support 114 are coupled to the top support 116. Further, each of the first support 112 and the second support 114 includes an outer suspending surface 118. The outer suspending surface 118 may be configured to mount the first guiding plate 108 and the second guiding plate 110 on which a light source 122 and a light guiding portion 124 may be mounted. Specifically, the first guiding plate 108 may be configured to mount a first guiding portion 124A thereon while the second guiding plate 110 may be configured to mount a second light guiding portion 124B. In one example, the outer suspending surface 118 may be attached to the first guiding plate 108 and the second guiding plate 110 by fastener while in another example, the outer suspending surface 118 may be attached to the first guiding plate 108 and the second guiding plate 110 by snap locks.

In one example, the outer suspending surface 118 may include a first articulated section 148 and a second articulated section 150. The first articulated section 148 and the second articulated section 150 may be configured to perform two tasks. First, the first articulated section 148 and the second articulated section 150 may be configured to support the light guiding portion 124 on and second, the first articulated section 148 and the second articulated section 150 may form a cavity 130 to house wires for the light source 122.

In one example, each of the first support 112 and the second support 114 may include an inner suspending surface 126. The inner suspending surface 126 may face each other and may define a space therebetween. The inner suspending surface 126 may include a plurality of slot 128 that may be present along the complete length of the housing 106. The slots 128 are positioned along the inner suspending surface 126 in such a way that the slots may face each other and are coplanar to form a mount. The mount may be used to mount a first auxiliary device thereon. The slots 128 may also be used to secure the wires of the light source 122 to the housing 106 to prevent wire entanglement.

Similarly, the top support 116 may include an inner suspending surface 132 that may face into the space. The inner suspending surface 132 may also include slots 134 like the slots 128 on the first support 112 and the second support 114. Further, the slots 134 may also form another mount to install the second auxiliary device in the space. In one example, the second auxiliary device may be a driver unit 136 for the light source 122. In one example, the driver unit 136 may be sized as the width of the space to achieve interference fit therebetween. Such a fit may prevent relative play between the driver unit 136 and the housing 106.

On the other hand, the top support 116 may include an outer suspending surface 138 opposite to the inner suspending surface 132. The outer suspending surface 138 may face the ceiling and may be configured to suspend the housing 106 using the string 102 as shown in Figure 1 (A) and (B). The outer suspending surface 138 may include a hole 120 (shown in Figure 1(B)) to allows passage of wires for the driver unit 136. The outer suspending surface 138 may be configured to receive the locking mechanism 104 that may couple the housing 106 to the string 102. As shown in Figure 1(A) two locking mechanisms 104 are used to suspend the housing 106 although a greater or lesser number of locking mechanisms 104 may be used. Further, the locking mechanism 104 may enable easy mounting and dismounting of the housing 106. Referring now to Figure 3, the outer suspending surface 138 also may include additional slots 140 that may run along the length of the outer suspending surface 138. In one example, the slot 140 may include a flange 142 that bends inward. The slots 140 may be configured to receive a third auxiliary device. Referring now to Figure 1 (C), the third auxiliary device may be, but is not limited to, a Wireless-Fidelity (Wi-Fi) router 146 and a motion sensor 158.

In one example, the housing 106 may also include the first guide plate 108 and the second guide plate 110. Details of the first guide plate 108 and the second guide plate 110 are explained with respect to Figure 2 in conjunction with Figure 4 that illustrates detailed schematics of the first guide plate 108 and the second guide plate 110. The present elaboration is with respect to the first guide plate 108 and the same elaboration applies mutatis mutandis on the second guide plate 110. The first guide plate 108 may have an L-shaped profile and may include a vertical section 152 and a horizontal section 154. Further, the vertical section 152 may be coupled to a flange 156 of the first support 112. Similarly, the vertical section 152 of the second guide plate 110 is coupled to a flange 156 of the second support 114. In addition, the vertical section 152 may include fins 160 facing towards the space that may perform various tasks. First, the fins 160 may act as a heat sink to dissipate the heat generated from the light source 122. In addition, the fins 160 may enable the mounting of a packing element 162 to prevent play between the driver unit 136 and the housing 106. In addition, the vertical section 152 may also form a part of the space within the housing 106.

In one example, the horizontal section 154 may be orthogonal to the vertical section 152. Further, the horizontal section 154 may be configured to mount the light guiding portions 124A, 124B thereon. For instance, the horizontal section 154 may be adapted to receive a fastener 164 to secure the light guiding portions 124A, 124B. In addition, the horizontal section 154 may form a boundary of the cavity 130 on either side of the housing 106, such that the cavity 130 accommodates a portion of the light guiding portions 124A, 124B. When mounted to the horizontal section 154, the light guiding portions 124A, 124B are coplanar, such that the illumination by the light guiding portions 124A, 124B is homogenous.

Referring now to Figure 2, while the first guide plate 108 and the second guide plate 110 defines the side of the space, the housing 106 may be a bottom plate 166 that may form a bottom boundary of the space. The bottom plate 166 may be coupled to the ends of the first guide plate 108 and the second guide plate 158 using locks, such as snap locks as shown in Figure 2. In one example, the bottom plate 166 may be configured to cover the ends of the fasteners 164 thereby enhancing the aesthetics of the housing 106.

Details of the bottom plate 166 are now explained in conjunction with Figure 5 that illustrates a side view of the bottom plate 166. The bottom plate 166 may include a horizontal section 168 that may form a major section of the bottom plate 166. The bottom plate 166 may also include a pair of slope section 170 extending from either side of the horizontal section 168. Finally, the bottom plate 166 may also include an L-shaped flange section 172 that extends from the ends of the slope section 170. The L-shaped flange section 172 may couple to the ends of the first guide plate 108 and the second guide plate 110.

Details of the locking mechanism 104 are now disclosed with respect to Figure 2 in conjunction with Figures 6, 7, and 8. Specifically, Figure 6 illustrates a top view (A), a front view (B), and a side view (C) of the assembled locking mechanism 104 having a base portion 174 and a locking portion 176. Further, Figure 7 illustrates a top view (A), a front view (B), and a side view (C) of the base 174. Furthermore, Figure 8 illustrates a top view (A), a front view (B), and a side view (C) of the locking portion 176. The locking mechanism 104 may be used to suspend the housing 106 to the ceiling. In one example, the base portion 174 may be secured to the housing 104 while the locking portion 176 may be attached to the string.

Referring now to Figures 6 and 7, the base portion 174 may be in the form of a flat plate. The base portion 174 may also include a pair of holes 178 adapted to receive fasteners to mount the base portion 174 to the housing 106. The base portion 174 may include a pair of base flanges 180 that extends from the base portion 174, such that the base flanges 180 are orthogonal to the top support 116 (shown in Figure 2). Further, as shown clearly in Figure 7 (C), each base flange 180 has a locking slot 182. The locking slot 182 may be adapted to secure the locking portion 176 thereon. The locking slot 182 may include an inclined section 184 that is open from one side of the base flange 180. In addition, the locking slot 182 includes a vertical section 186 that extends from one end of the inclined section 184. The vertical section 186 is adapted to secure the locking portion 176 thereto and is designed in such a way that the locking portion 176 does not get dislodged from the vertical section 186 due to vibration and may only be dislodged when removed by the user.

In one example, the locking portion 176 may have a structure to complement the base portion 174. Referring now to Figures 6 and 8, the locking portion 176 may include a pair of locking flanges 188. In one example, the locking flanges 188 may have a length less than the length of the base flange 174 shown in Figure 6. In one example, the locking flange 188 may include a hole 190 that may be adapted to receive an adapter of the string to suspend the locking portion 176. In one example, the hole 190 may be present at the centre of the locking portion 176. The locking portion 176 may include a pair of locks 192 on each of the locking flange 188.

Referring now to Figure 8, the lock 192 may include a head 194 and a body 196. The body 196 may be adapted to be inserted into a hole (not visible) in the locking portion 176, such that the body 196 may rotate with respect to the locking flange 188. Moreover, a portion of the body 196 and the head 194 may protrude from the locking flange 188. In one example, the portion of the body 196 is called as the neck. The lock 192 may also include a lever 198 that may extend from the head 194. In one example, the lever 198 may allow the user to rotate the lock 192 with respect to the locking flange 188. Moreover, the lever 196 may also prevent the rotation of the lock 192 when the lock is inserted in the locking slot 182.

During assembly, the lock 192 and the locking slot 182 enables easy suspending and removal of the housing 106 without the need of tools to suspend the lighting apparatus 100. For instance, the lock 192 can easily be slid into the inclined section 184 and then into the vertical section 186. Thereafter, the lever 196 may be slid downward to secure the lock 192 in the locking slot 182. Moreover, the weight of the housing 104 causes the lock 192 to abut against the end of the vertical section 186. Further, in order to remove the lock 192 from the locking slot 182, the housing 106 may be lifted and the lever 196 may be operated to guide the lock 192 from the vertical section 186 to the inclined section 184 and out from the locking slot 182.

According to the present disclosure, the first guide plate 108 and the second light guide plate 110 ensures that the light guiding portions 124A, 124B are coplanar that ensures homogenous light dispersion by the lighting apparatus 100. Moreover, the first guide plate 108 and the second light guide plate 110 enables better heat dissipation from the light source 122 thereby ensuring a longer operational life of the light source 122.

While specific language has been used to describe the present disclosure, any limitations arising on account thereto, are not intended. As would be apparent to a person in the art, various working modifications may be made to the method in order to implement the inventive concept as taught herein. The drawings and the foregoing description give examples of embodiments. Those skilled in the art will appreciate that one or more of the described elements may well be combined into a single functional element. Alternatively, certain elements may be split into multiple functional elements. Elements from one embodiment may be added to another embodiment. ,CLAIMS:1. A lighting apparatus (100) comprising:
