DESC:FIELD OF THE INVENTION

The present disclosure relates to lighting apparatuses and more particularly, relates to an improved lighting apparatus with Driver on Board (DOB) module.

BACKGROUND

Generally, lighting apparatus, such as a lighting batten, includes a light diffuser and a plurality of Light Emitting Diodes (LEDs) adapted to emit light. In such lighting apparatus, the plurality of LEDs is supported on a light substrate disposed in the lighting apparatus. In one implementation, the lighting apparatus includes the light substrate along with a separate LED driver adapted to drive the plurality of LEDs disposed on the light substrate. In another implementation, the lighting apparatus includes the light substrate which is embodied as a Driver on Board (DOB) module. In such a DOB based light substrate, the plurality of LEDs is disposed on the light substrate along with various components configured to drive the aforesaid LEDs. Therefore, dimensional and constructional aspects for both the types of light substrates are different from each other.

Hence, implementation of the DOB based light substrate in the lighting apparatus requires a housing member that is capable of firmly holding such light substrate within the lighting apparatus at an optimal distance from the light diffuser. Further, in order to suppress uneven brightness in the lighting apparatus, it is essential to secure the plurality of LEDs of the light substrate at a sufficient distance from each other. Although, such an arrangement of the plurality of LEDs and constructional aspects of the housing member to employ the DOB based light substrate may substantially increase the overall size of the lighting apparatus which is not suitable. Therefore, there is a need for an improved lighting apparatus with a housing member capable of effectively securing the light substrates, such as the DOB based light substrate, within the lighting apparatus.

Figure 1 illustrates an isometric view of an improved lighting apparatus 100, according to an embodiment of the present disclosure. The improved lighting apparatus 100 may interchangeably be referred to as the lighting apparatus 100. In an embodiment, the lighting apparatus 100 may be embodied as a lighting batten, without departing from the scope of the present disclosure. The lighting apparatus 100 may be adapted to be positioned in different orientations to illuminate the area in the vicinity of the lighting apparatus 100. In one example, the lighting apparatus 100 may be positioned on a vertical surface, such as a wall. In another example, the lighting apparatus 100 may be positioned on a horizontal surface, such as a roof. Constructional and operational aspects of the lighting apparatus 100 are explained in subsequent sections of the present disclosure.

Figure 2 illustrates a partial isometric view of the lighting apparatus 100, according to an embodiment of the present disclosure. Figures 3a and 3b illustrate side views of the lighting apparatus 100, according to an embodiment of the present disclosure. Referring to Figure 2, Figure 3a, and Figure 3b, in the illustrated embodiment, the lighting apparatus 100 may include, but is not limited to, a plurality of light sources 202, a light substrate 204, a housing member 206, and a mounting clamp 402 (as shown in Figure 4). The light substrate 204 may be adapted to support the plurality of light sources 202 to emit light. In an embodiment, the plurality of light sources 202 may be embodied as Light Emitting Diodes (LEDs), without departing from the scope of the present disclosure. Further, the light substrate 204 may be embodied as a Driver on Board (DOB) module. In the illustrated embodiment, the plurality of light sources 202 may be distributed on the light substrate 204 along a length ‘L’ of the housing member 206.

In an embodiment, the housing member 206 may be adapted to encapsulate the light substrate 204 and the plurality of light sources 202 supported on the light substrate 204. The housing member 206 may include, but is not limited to, a light diffuser 208, a support surface 210, and a pair of side walls 212. In the illustrated embodiment, the light diffuser 208 may have a hemispherical contour, without departing from the scope of the present disclosure. The light diffuser 208 may be adapted to cover the plurality of light sources 202 and adapted to scatter light emitted from the plurality of light sources 202.

Referring to Figure 3a and 3b, the support surface 210 of the housing member 206 may be positioned below the light diffuser 208. The support surface 210 may be adapted to support the light substrate 204. In the illustrated embodiment, the support surface 210 may be embodied as a flat surface, without departing from the scope of the present disclosure. Further, referring to Figure 2 and Figures 3a-3b, the pair of side walls 212 may be defined between the light diffuser 208 and the support surface 210. The pair of side walls 212 may individually be referred to as a first side wall 212-1 and a second side wall 212-2. Each of the first side wall 212-1 and the second side wall 212-2 may include an inner surface 214 and an outer surface 216.

Further, the housing member 206 may include, but is not limited to, a substrate holder 218 adapted to hold the light substrate 204 on the support surface 210 of the housing member 206. The support surface 210, the pair of side walls 212, and the substrate holder 218 may collectively define a partially opened channel 302 adapted to hold the light substrate 204. The inner surface 214 of each of the pair of side walls 212 may be provided with the substrate holder 218 adapted to push edges of the light substrate 204 towards the support surface 210. The substrate holder 218 may include a pair of projections 220 formed on the inner surface 214 of the pair of side walls 212. The pair of projections 220 may individually be referred to as a first projection 220-1 and a second projection 220-2.

In the illustrated embodiment, referring to Figure 3a and 3b, the first projection 220-1 may be provided at the inner surface 214 of the first side wall 212-1 of the housing member 206. Similarly, the second projection 220-2 may be provided at the inner surface 214 of the second side wall 212-2 of the housing member 206. The first projection 220-1 and the second projection 220-2 may extend along the length ‘L’ of the housing member on the first side wall 212-1 and the second side wall 212-2, respectively. Upon positioning the light substrate 204 on the support surface 210, the first projection 220-1 and the second projection 220-2 may be adapted to push the edges of the light substrate 204 towards the support surface 210 and thereby, holding the light substrate 204 in the housing member 206.

Further, the outer surface 216 of the pair of side walls 212 may include a groove 222 adapted to be engaged with the mounting clamp 402. In the illustrated embodiment, the groove 222 formed on the outer surface 216 of the first side wall 212-1 may be interchangeably referred to as the groove 222-1. Similarly, the groove 222 formed on the outer surface 216 of the second side wall 212-2 may be interchangeably referred to as the groove 222-2. The mounting clamp 402 may be adapted to apply elastic force on the pair of side walls 212 to hold the housing member 206. The elastic force applied by the mounting clamp 402 may result in resilient deflection of the pair of side wall 212 in an inward direction. Owing to such deflection of the pair of side walls 212, the first projection 220-1 on the first side wall 212-1 and the second projection 220-2 on the second side wall 212-2 may firmly push the light substrate 204 towards the support surface 210 and thereby, holding the light substrate 204. Constructional details of the mounting clamp 402 are explained in the subsequent sections of the present disclosure.

Figures 4a and 4b illustrate a side view and a top view, respectively, of the mounting clamp 402 of the lighting apparatus 100, according to an embodiment of the present disclosure. As mentioned earlier, the lighting apparatus 100 may include the mounting clamp 402 adapted to engage with the housing member 206 to mount the housing member 206 on various surfaces, such as a wall and a roof. The mounting clamp 402 may include, but is not limited to, a first clamping surface 402-1, a second clamping surface 402-2, and a third clamping surface 402-3. Each of the first clamping surface 402-1 and the second clamping surface 402-2 is inclined at an obtuse angle with respect to the third clamping surface 402-3.

Referring to Figure 4a, in the illustrated embodiment, the first clamping surface 402-1 may be inclined at an obtuse angle ?1 with respect to the third clamping surface 402-3. Similarly, the second clamping surface 402-2 may be inclined at an obtuse angle ?2 with respect to the third clamping surface 402-3. The obtuse angle ?1 defined between the first clamping surface 402-1 and the third clamping surface 402-3 may be equal to the obtuse angle ?2 defined between the second clamping surface 402-2 and the third clamping surface 402-3. The third clamping surface 402-3 of the mounting clamp 402 may be adapted to coincide with the surface on which the lighting apparatus 100 is mounted.

The first clamping surface 402-1 and the second clamping surface 402-2 may be adapted to apply the elastic force on the pair of walls 212 of the housing member 206. The first clamping surface 402-1 and the second clamping surface 402-2 may include a first engaging portion 404-1 and a second engaging portion 404-2, respectively. The first engaging portion 404-1 may be adapted to engage with the groove 222-1 formed on the first side wall 212-1 of the housing member. Further, the second engaging portion 404-2 may be adapted to engage with the groove 222-2 formed on the second side wall 212-2 of the housing member 206. In an embodiment, a shape of the first engaging portion 404-1 and the second engaging portion 404-2 may conform with the contour of the groove 222-1 formed on the first side wall 212-1 and the groove 222-2 formed on the second side wall 212-2, respectively.

Figures 5a, 5b, and 5c illustrate different views of an end cap of the lighting apparatus 100, according to an embodiment of the present disclosure. Referring to Figure 5a, Figure 5b, and Figure 5c, in the illustrated embodiment, the lighting apparatus 100 may include a pair of end caps 502 adapted to be connected to a first end 206-1 and a second end 206-2 of the housing member 206 of the lighting apparatus 100. The pair of end caps 502 may be adapted to restrict ingress of any contaminants within the housing member 206, and thereby protecting various sub-components of the lighting apparatus 100 from such contaminants.

The pair of end caps 502 may include a first end cap adapted to be connected to the first end 206-1 and a second end cap adapted to be connected to the second end 206-2. Each of the pair of end caps 502 may be removably connected to one of the first end 206-1 and the second end 100-2 of the housing member 206. In the illustrated embodiment, each of the pair of end caps 502 includes a wedge-shaped protrusion 504 adapted to push the light substrate 204 in an axial direction along the length ‘L’ of the housing member 206.

The wedge-shaped protrusion 504 of the pair of end caps 502 may be adapted to be received in the partially opened channel 302 to push the light substrate 204 in the axial direction from each of the ends, such as the first end 206-1 and the second end 206-2, of the housing member 206. Owing to such positioning of the wedge-shaped protrusion 504 in the partially opened channel 302, the light substrate 204 may be firmly held in a position from both the ends 206-1, 206-2, of the housing member 206 within the partially opened channel 302. Further, the wedge-shaped protrusion 504 may be adapted to engage with the substrate holder 218 to hold the pair of end caps 502 in a position at both ends of the housing member 206.

As would be gathered, the present disclosure offers the lighting apparatus 100 having the substrate holder 218 adapted to hold the light substrate 204 within the housing member 206 of the lighting apparatus 100. As mentioned earlier, the housing member 206 may include the pair of side walls 212 provided with the substrate holder 218 to hold the light substrate 204 on the support surface 210 of the housing member 206. The pair of projections 220 of the substrate holder 218 may be adapted to hold the edges of the light substrate 204 supported on the support surface 210. Owing to such constructional aspects of the housing member 206, the light substrate 204 may be firmly held within the housing member 206 and further, a DOB based light substrate can also be implemented within the housing member 206 with ease.

Further, as explained earlier, the lighting apparatus 100 may include the mounting clamp 402 adapted to mount the housing member 206 on various surfaces. The first clamping surface 402-1 and the second clamping surface 402-2 may be adapted to apply the elastic force on the pair of side walls 212 of the housing member 206, when the mounting clamp 402 is coupled to the housing member 206. This results in slight resilient deflection of the pair of side walls 212 in the inward direction which ensures that the pair of projections 220 formed on the inner surface 214 of the pair of side walls 212 firmly holds the light substrate 204 on the support surface 210 of the housing member 206. Furthermore, the lighting apparatus 100 may include the pair of end caps 502 adapted to be removably coupled to the ends 206-1, 206-2 of the housing member 206. Each of the pair of end caps 502 may include the wedge-shaped projection 504 adapted to push the light substrate 204 in the axial direction from both the ends 206-1, 206-2 within the housing member 206. This ensures that the light substrate 204 is firmly positioned within the housing member 206 of the lighting apparatus 100. Therefore, the lighting apparatus 100 of the present disclosure is flexible in implementation, compact, efficient, cost-effective, aesthetically appealing, and convenient.

While specific language has been used to describe the present subject matter, 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:FIELD OF THE INVENTION

Referring to Figure 3a and 3b, the support surface 210 of the housing member 206 may be positioned below the light diffuser 208. The support surface 210 may be adapted to support the light substrate 204. In the illustrated embodiment, the support surface 210 may be embodied as a flat surface, without departing from the scope of the present disclosure. Further, referring to Figure 2 and Figures 3a-3b, the pair of side walls 212 may be defined between the light diffuser 208 and the support surface 210. The pair of side walls 212 may individually be referred to as a first side wall 212-1 and a second side wall 212-2. Each of the first side wall 212-1 and the second side wall 212-2 may include an inner surface 214 and an outer surface 216.

Further, the housing member 206 may include, but is not limited to, a substrate holder 218 adapted to hold the light substrate 204 on the support surface 210 of the housing member 206. The support surface 210, the pair of side walls 212, and the substrate holder 218 may collectively define a partially opened channel 302 adapted to hold the light substrate 204. The inner surface 214 of each of the pair of side walls 212 may be provided with the substrate holder 218 adapted to push edges of the light substrate 204 towards the support surface 210. The substrate holder 218 may include a pair of projections 220 formed on the inner surface 214 of the pair of side walls 212. The pair of projections 220 may individually be referred to as a first projection 220-1 and a second projection 220-2.

In the illustrated embodiment, referring to Figure 3a and 3b, the first projection 220-1 may be provided at the inner surface 214 of the first side wall 212-1 of the housing member 206. Similarly, the second projection 220-2 may be provided at the inner surface 214 of the second side wall 212-2 of the housing member 206. The first projection 220-1 and the second projection 220-2 may extend along the length ‘L’ of the housing member on the first side wall 212-1 and the second side wall 212-2, respectively. Upon positioning the light substrate 204 on the support surface 210, the first projection 220-1 and the second projection 220-2 may be adapted to push the edges of the light substrate 204 towards the support surface 210 and thereby, holding the light substrate 204 in the housing member 206.

Further, the outer surface 216 of the pair of side walls 212 may include a groove 222 adapted to be engaged with the mounting clamp 402. In the illustrated embodiment, the groove 222 formed on the outer surface 216 of the first side wall 212-1 may be interchangeably referred to as the groove 222-1. Similarly, the groove 222 formed on the outer surface 216 of the second side wall 212-2 may be interchangeably referred to as the groove 222-2. The mounting clamp 402 may be adapted to apply elastic force on the pair of side walls 212 to hold the housing member 206. The elastic force applied by the mounting clamp 402 may result in resilient deflection of the pair of side wall 212 in an inward direction. Owing to such deflection of the pair of side walls 212, the first projection 220-1 on the first side wall 212-1 and the second projection 220-2 on the second side wall 212-2 may firmly push the light substrate 204 towards the support surface 210 and thereby, holding the light substrate 204. Constructional details of the mounting clamp 402 are explained in the subsequent sections of the present disclosure.

Figures 4a and 4b illustrate a side view and a top view, respectively, of the mounting clamp 402 of the lighting apparatus 100, according to an embodiment of the present disclosure. As mentioned earlier, the lighting apparatus 100 may include the mounting clamp 402 adapted to engage with the housing member 206 to mount the housing member 206 on various surfaces, such as a wall and a roof. The mounting clamp 402 may include, but is not limited to, a first clamping surface 402-1, a second clamping surface 402-2, and a third clamping surface 402-3. Each of the first clamping surface 402-1 and the second clamping surface 402-2 is inclined at an obtuse angle with respect to the third clamping surface 402-3.

Referring to Figure 4a, in the illustrated embodiment, the first clamping surface 402-1 may be inclined at an obtuse angle ?1 with respect to the third clamping surface 402-3. Similarly, the second clamping surface 402-2 may be inclined at an obtuse angle ?2 with respect to the third clamping surface 402-3. The obtuse angle ?1 defined between the first clamping surface 402-1 and the third clamping surface 402-3 may be equal to the obtuse angle ?2 defined between the second clamping surface 402-2 and the third clamping surface 402-3. The third clamping surface 402-3 of the mounting clamp 402 may be adapted to coincide with the surface on which the lighting apparatus 100 is mounted.

The first clamping surface 402-1 and the second clamping surface 402-2 may be adapted to apply the elastic force on the pair of walls 212 of the housing member 206. The first clamping surface 402-1 and the second clamping surface 402-2 may include a first engaging portion 404-1 and a second engaging portion 404-2, respectively. The first engaging portion 404-1 may be adapted to engage with the groove 222-1 formed on the first side wall 212-1 of the housing member. Further, the second engaging portion 404-2 may be adapted to engage with the groove 222-2 formed on the second side wall 212-2 of the housing member 206. In an embodiment, a shape of the first engaging portion 404-1 and the second engaging portion 404-2 may conform with the contour of the groove 222-1 formed on the first side wall 212-1 and the groove 222-2 formed on the second side wall 212-2, respectively.

Figures 5a, 5b, and 5c illustrate different views of an end cap of the lighting apparatus 100, according to an embodiment of the present disclosure. Referring to Figure 5a, Figure 5b, and Figure 5c, in the illustrated embodiment, the lighting apparatus 100 may include a pair of end caps 502 adapted to be connected to a first end 206-1 and a second end 206-2 of the housing member 206 of the lighting apparatus 100. The pair of end caps 502 may be adapted to restrict ingress of any contaminants within the housing member 206, and thereby protecting various sub-components of the lighting apparatus 100 from such contaminants.

The pair of end caps 502 may include a first end cap adapted to be connected to the first end 206-1 and a second end cap adapted to be connected to the second end 206-2. Each of the pair of end caps 502 may be removably connected to one of the first end 206-1 and the second end 100-2 of the housing member 206. In the illustrated embodiment, each of the pair of end caps 502 includes a wedge-shaped protrusion 504 adapted to push the light substrate 204 in an axial direction along the length ‘L’ of the housing member 206.

The wedge-shaped protrusion 504 of the pair of end caps 502 may be adapted to be received in the partially opened channel 302 to push the light substrate 204 in the axial direction from each of the ends, such as the first end 206-1 and the second end 206-2, of the housing member 206. Owing to such positioning of the wedge-shaped protrusion 504 in the partially opened channel 302, the light substrate 204 may be firmly held in a position from both the ends 206-1, 206-2, of the housing member 206 within the partially opened channel 302. Further, the wedge-shaped protrusion 504 may be adapted to engage with the substrate holder 218 to hold the pair of end caps 502 in a position at both ends of the housing member 206.

As would be gathered, the present disclosure offers the lighting apparatus 100 having the substrate holder 218 adapted to hold the light substrate 204 within the housing member 206 of the lighting apparatus 100. As mentioned earlier, the housing member 206 may include the pair of side walls 212 provided with the substrate holder 218 to hold the light substrate 204 on the support surface 210 of the housing member 206. The pair of projections 220 of the substrate holder 218 may be adapted to hold the edges of the light substrate 204 supported on the support surface 210. Owing to such constructional aspects of the housing member 206, the light substrate 204 may be firmly held within the housing member 206 and further, a DOB based light substrate can also be implemented within the housing member 206 with ease.

Further, as explained earlier, the lighting apparatus 100 may include the mounting clamp 402 adapted to mount the housing member 206 on various surfaces. The first clamping surface 402-1 and the second clamping surface 402-2 may be adapted to apply the elastic force on the pair of side walls 212 of the housing member 206, when the mounting clamp 402 is coupled to the housing member 206. This results in slight resilient deflection of the pair of side walls 212 in the inward direction which ensures that the pair of projections 220 formed on the inner surface 214 of the pair of side walls 212 firmly holds the light substrate 204 on the support surface 210 of the housing member 206. Furthermore, the lighting apparatus 100 may include the pair of end caps 502 adapted to be removably coupled to the ends 206-1, 206-2 of the housing member 206. Each of the pair of end caps 502 may include the wedge-shaped projection 504 adapted to push the light substrate 204 in the axial direction from both the ends 206-1, 206-2 within the housing member 206. This ensures that the light substrate 204 is firmly positioned within the housing member 206 of the lighting apparatus 100. Therefore, the lighting apparatus 100 of the present disclosure is flexible in implementation, compact, efficient, cost-effective, aesthetically appealing, and convenient.
