DESC:FIELD OF THE INVENTION

The present disclosure relates to a lighting apparatus and an adjustable mount for the lighting apparatus.

BACKGROUND

Light emitting diode or 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 a preferrable choice in making lighting devices, such as light bulbs or battens. Moreover, the LEDs, owing to their small form factor and flexibility in manufacturing can be manufactured as an LED lighting device in different shapes. Such LED lighting devices are made by combining multiple LED units in pre-defined shapes, such as in a disc shape or in a batten shaped. The batten shape lights are generally mounted on the ceiling at a pre-defined orientation with respect to the wall based on the region of illumination. Generally, the LED has a limited beam angle unlike the fluorescent light or incandescent light. As a result, the LED are placed on a mount and positioned in a pre-defined orientation on the mount.

There are various limitations associated with the current setups to mount the LED lighting device. For instance, the current mounts attach the LED lighting device to the wall in a fixed-predefined orientation. Some of the recent mounts attach the LED via an adjustable mechanism that can orient the LED lighting device. However, such mounts are not robust. Moreover, such mechanisms are integrated into the mount and the LED lighting device thereby making the replacement of a damaged LED lighting device difficult. In some scenarios, damage to one LED unit can render the complete LED lighting device useless.

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 mount for mounting the lighting apparatus on a wall. The mount is retrofittable and enables mounting of currently used lighting apparatus.

In an embodiment, a lighting apparatus is disclosed that includes at least one mount that removably mounts a light source thereon. The mount includes a base unit and a clamp attached to the base unit. The base unit includes a platform mountable on a surface and a pair of walls extending orthogonally from the platform. Further, each pair wall of the pair of the walls includes an involute gear profile.

In another embodiment, the light source may include a tubular housing having a first end and a second end and a wall including a light diffuser between the first end and the second end. In one example, the first end and the second end are removably attached to the at least one mount. The light source may also include a LED substrate installed axially inside the tubular housing and facing the light diffuser, and a driver coupled to the LED substrate. The driver is configured to convert AC mains to DC current to power the LED substrate.

According to the present disclosure, the meshing between the pair of gears on the clamp and the involute gear profile of the base unit enables the clamp to attain different angular orientations with respect to the wall. Further, other gear profiles may also enable the clamp to attain different orientations with respect to the base unit. Moreover, the clamp is designed to receive both the light source of the present disclosure and currently available light sources thereby making the lighting apparatus retrofittable resulting in a less infrastructural overall cost.

For example, reference numerals starting with digit “1” are shown at least in Figure 1. Similarly, reference numerals starting with digit “2” are shown at least in Figure 2.

Figures 1 and 2 illustrate a lighting apparatus 100, according to an embodiment of the present disclosure. Specifically, Figure 1 illustrates the light apparatus 100 mounted on a wall W while Figure 2 illustrates different orientations of the lighting apparatus 100 with respect to the wall W. The lighting apparatus 100 may be employed to provide illumination in a space that has a wall W. The lighting apparatus 100 can be mounted on the wall W in such a way that the lighting apparatus 100 can attain different orientations with respect to the wall W. The lighting apparatus 100 may include one or more mount 102 and a light source 104 removably mounted on the mount 102. The light source 104 is configured to illuminate the space in which the lighting apparatus 100 is installed. The light source 104 can be based on Light Emitting Diode (LED) and may have a beam angle. In one example, the beam angle can be between 1100 to 1200. The light source 104 can be a batten.

Details of the light source 104 are now explained with respect to Figure 3. Specifically, Figure 3(a) illustrates a perspective view of one end of the light source 104 while Figure 3(b) illustrates a cross-section taken along lines 1-1 in Figure 3(a). The light source 104 may include a tubular housing 106 that has a first end 108A and a second end 108B. The tubular housing 106 may have a partially semi-circular shape wall 110 along the length of the tubular housing 106 between the first end 108A and the second end 108B. The tubular housing 106 may include a printed circuit board (PCB) 112 that may be installed axially in the tubular housing 106. The PCB 112 may be secured inside a channel formed by a bottom surface 114 and a pair of lips 116 inside the tubular housing 106. The light source 104 may include a LED substrate 118 installed on the PCB 112. In one example, the LED substrate 118 may be in the form of an array of LEDs axially soldered on the PCB 112. Further, the PCB 112 can be removed from the housing 104 in case of failure of the LED substrate 118. Further, in order to spread the light emitted from the LED substrate 118, the wall includes a light diffuser that uniformly disperses the light exiting from the tubular housing 104.

In one example, the housing 106 may be configured to the component that powers the LED substrate 118. In another example, the housing 103 may include a compartment to hold the components to power the LED substrate 118. For example, the housing 106 may include the compartment that holds a driver to power the LED substrate 118. In addition, the compartment may also house the wires that connects the PCB to the driver. Although not shown, the housing 106 may include endcaps that may be employed to fix the housing 106 in its position. In addition, the housing 106 may include a groove 119 on either side of the housing 106 along a length of the housing 106. The grooves 119 may be adapted to attach the housing 106 to the mount 102.

Referring back to Figure 1, the mount 102 is adapted to removably receive the light source 104. The mount 102 is designed to receive the light source 104, such that the light source 104, is installed in the mount 102 by a press fit. In one example, the lighting apparatus 100 may include two mounts 102 to install the light source 104 on the wall W although additional mounts 102 may be used based on the overall length of the light source 104. The mounts 102 may be configured to install the light source 104 at different angular orientations. Referring now to Figure 2, the mount 102 may be configured to aim the light source 104 in different orientations. For instance, the mount 102 may be configured to orient the light source 104 parallel to the floor F as shown in (a) also called normal lighting mode. In another instance, the mount 102 may orient the light source 104, such that the light source 104 faces towards the ceiling or away from the floor F as shown in (b) also known as façade lighting mode or indirect lighting mode. In yet another instance, the mount 102 may orient the light source 104 to face towards the floor F as shown in (c) also known as direct lighting mode. In either case, the orientation of the light source 104 may be based on the type of one of the lighting modes.

In one example, the mount 102 may be formed of two components, namely a base unit 120 and a clamp 122. The base unit 120 may be installed on the wall W while the clamp 122 may be configured to removably receive the light source 104. In one example, the clamp 122 may be pivotably coupled to the base unit 120, such that the clamp 122 can pivot with respect to the base unit 120. Details of the base unit 120 are explained with respect to Figures 4, 5, and 6 and details of the clamp 122 are explained with respect to Figures 7, 8, and 9.

Referring now to Figures 4, 5, and 6 that illustrates various views of the base unit 120. Specifically, Figure 4 illustrates a side view of a base unit 120 of the lighting apparatus 100 while Figure 5 illustrates a front view of the base unit 120 of the lighting apparatus 100. Further, Figure 6 illustrates a top view of the base unit 120 of the lighting apparatus 100. The base unit 120 can be used to anchor or secure the mount 102. The base unit 120 may include a platform 124 that forms the lower portion of the base unit 120. The platform 124 can be a rectangle-shaped plate. The platform 124 may include a hole 126, shown in Figure 6, that can receive a fastener to mount the platform 124 on the wall W (shown in Figure 1). The base unit 120 may also include a pair of walls 128 on either end of the platform 124. The walls 128 may extend orthogonally from the platform 124. As may be understood, the walls 128 may define the height of the base unit 120. Further, the walls 128 may be separated from each other by platform 124, such that the distance between the walls 128 may define the width of the base unit 120.

In one example, the walls 128 can have different shapes and/or profiles. For instance, each wall 128 may have curved edges that rises from an end of the wall 128 attached to the platform 124. Each wall 128 may include a cut-out portion at another end of the wall 128. Further, the cut-out portion may include internal gear that has a gear profile 130, which, in one example, can be an involute gear profile 130. The cut-out portion may enable a user to effortlessly mount or dismount the clamp 122 from the base unit 120. On the other hand, the involute gear profile 130 may assist the clamp 122 to pivot about the walls 128. Although the present illustration shows the involute gear profile 130 in the semi-circular cut-out portion, the involute gear profile 130 may be formed as a hole in the wall 128. Further, the involute gear profile 130 may remain substantially parallel to the ground in either of the positions shown in Figure 2.

Details of the clamp 122 are now explained with respect to Figure 7, 8, and 9. Specifically, Figure 7 illustrates a side view of the clamp 122 of the lighting apparatus 100 while Figure 8 illustrates a front view of the clamp 122 of the lighting apparatus 100. Further, Figure 9 illustrates a top view of the clamp 122 of the lighting apparatus 100. The clamp 122 may be attached to the base unit 120, such that the clamp 122 can pivot with respect to the base unit 120 and attain a range of different angular orientations with respect to the base unit 120.

The clamp 122 may include a mounting portion 132, a holding portion 134, and a neck 136. The mounting portion 132 is configured to be mounted on the base unit. The mounting portion 132 may be configured to perform two tasks. First, the mounting portion 132 may be configured to secure the clamp 122 to the base unit 120 and second, the mounting portion 132 may be configured to facilitate the pivoting of the holding portion 134 with respect to the base unit 120. The mounting portion 132 may include a pair of gears 138 on either side on the mounting portion 132. In one example, the gears 138 may be configured to mesh with the involute gear profile shown in Figure 3. Further, the gears 138 can be spur gear whose gear profile matches with the involute gear profile 130 (shown in Figure 5).

In one example, the holding portion 134 may include a pair of side walls 140 and a base wall 142. The base wall 142 may be coupled to the neck 136 and side walls 140 may extend orthogonally from the base wall 142. The side walls 140 may be profiled to receive the light source 104 as shown in Figure 2. For instance, each side wall 140 has a vertical section extending from the neck 136. Further, the side wall 140 has a curved section at which the width of the holding portion 134 is reduced. The side wall 140 also includes another vertical section at the top that extends from the curved section. Further, the holding portion 134 is sized to receive the tubular housing 106. During the mounting of the light source 104, the side walls 140 may flex when the tubular housing 106 is inserted in the clamp 122, such that the light source 104 abuts the side walls 140 and a press-fit is achieved between the light source 104 and the curved section. In one example, the groove 119 may be inserted in the curved section of the clamp 122 to secure the light source 104 to the clamp 122.

In one example, the neck 136 couples the holding portion 134 to the mounting portion 132. In one example, the neck 136 may be rigidly coupled to the holding portion 134 and is pivotably coupled to the mounting portion 132, such that the neck 136 and the holding portion 134 can pivot with respect to the mounting portion 132. Further, the meshing of the gears 138 and the involute gear profile 130 allows the mounting portion 132 to remain stationary while enabling pivoting of the holding portion 134 and the neck 136.

Although the present illustration shows curved section of the side walls 140 to achieve press fit, different designs can be envisioned within the scope of the present disclosure. An exemplary embodiment of the different designs of the clamp and the mount based on the clamp is explained with respect to Figures 10 and 11. Specifically, Figure 10 shows different views of a clamp 1022 and Figure 11 shows a mount 1100 based on the clamp 1022. The clamp 1022 may have similar construction features as the clamp 122. For instance, the clamp 1022 may include a mounting portion 1032, a holding portion 1034, and a neck 1036. Further, the mounting portion 1032 and the neck 1036 are identical to the mounting portion 132 and the neck 136 shown in Figure 7 and hence are not discussed again for brevity.

In one example, the holding portion includes a pair of side walls 1040 and a base wall 1042, such that the base wall 1042 is attached to the neck 136 and the side walls 1040 extends orthogonally from the base wall 1042. Further, each side wall 1040 is profiled to have a parabolic shape, such that the width of the side wall 1040 at the base wall 1042 is greater than the width between the side wall 1040 at their respective open ends. As a result, the light source 104, when inserted in the holding portion 1034. Further, each open end includes a lip 1002 that may act as an arrester for the light source 104 when installed in the clamp 1022.

Further, the clamp 1022 may assume different angular orientations as shown in Figure 11. Specifically, the clamp 1022 can be parallel to the floor as shown in Figure 11(a) or inclined as shown in Figure 11(b) and 11(c). As may be understood, the base unit 120 may enable the clamp 1022 to attain different pre-defined angular orientations with respect to the base unit 120.

During assembly, the base unit 120 may be mounted on a platform and thereafter, the gears 138 of mounting portion 132 have meshed with the involute gears profile 130 of the walls 128. The same process is repeated to assemble multiple mounts 102. In order to assemble the lighting apparatus 100, the mounts 102 can be attached to the wall W. In one example, the base unit 120 may be installed on the wall W by inserting and fastening a fastener through the hole 126 of the base unit 120. A similar step is repeated for the other mount 102. Thereafter, the clamp 122 of each mount 102 may be adjusted to attain a pre-defined orientation with respect to the wall W as shown in Figure 2(a). Once oriented, the light source 104 may be inserted into the clamp 122. In one example, the first end 108A of the tubular housing 106 may be inserted in one mount 102 while the second end 108B of the tubular housing may be inserted in another mount 102. Thereafter, the first end 108A and the second end 108B may be pushed into the clamp 122, such that press-fit is achieved between the side walls 140 and the tubular housing 106.

In case the angular orientation of the light source 104 is to be changed, the first end 108A and the second end 108B may be pushed either upward or downward by a user, such that the holding portion 134 and the neck 136 of each clamp 122 are forced to pivot about the mounting portion 132 and the base unit 120. In one example, the meshing between the gears 138 and the involute gears profile 130 enables the holding portion 134 and the neck 136 to pivot thereby attaining another pre-defined orientation as shown in Figure 2(b) or Figure 2(c).

According to the present disclosure, the provision of pivoting of the clamp 122, 1022 with respect to the base unit 120 enables adjustment in the beam angle and throw of the light source. Moreover, removable installation of the light source enables easy replacement of defective light sources. Moreover, the clamp 122, 1022 can receive an existing light source thereby making the mount 102 retrofittable.

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:We Claim:
