DESC:FIELD OF THE INVENTION

The present disclosure relates to a battening apparatus having ends caps to dissipate heat.

BACKGROUND

Battens are long and sleek lighting devices used for illumination. A batten has a strip of light-emitting diodes (LEDs) installed longitudinally in the housing of the batten. The batten also includes a diffuser that diffuses the light emitted by the LEDs to maintain uniform light emission and conceal the LED. Further, the batten has a lower chamber to house various other components of the batten, such as a driver unit for the LEDs. The battens are designed to achieve uniform light diffusion. Generally, the batten is made taller to achieve the requisite lumen output.

There are various limitations associated with the current design of the battens. For instance, the battens are tall which increases the amount of material needed to manufacture the batten. One way to mitigate this issue is to reduce the size of either of the housing or of the diffuser. However, reducing the size of the diffuser reduces the lumen output. In order to enhance the lumen output, a powerful LED may be used. However, the use of larger powered LED becomes visible through the diffuser resulting in non-uniform light emission and defeating the purpose of the diffuser to conceal the light source. Similarly, reducing the size of the housing reduces the distance between the diffuser and the LEDs, thereby revealing the location of the LED and also leading to non-uniform light emission from the batten.

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.

In an embodiment, a lighting apparatus is disclosed that includes a housing and a lighting cover attached to the housing and adapted to diffuse light. The lighting apparatus also includes a base disposed between the housing and the lighting cover. Further, the base includes a longitudinal slot along the length of the flat horizontal reflector and a pair of horizontal reflectors on either side of the longitudinal slot and adapted to reflect light incident thereupon towards the inner walls of the lighting cover. The lighting apparatus is also a light source installed at a bottom of the longitudinal slot, wherein the light source is adapted to emit light.

According to the present disclosure, the lighting apparatus is a compact device that has an additional reflective surface that enhances the light emission without revealing the position of the light source inside the lighting apparatus. For instance, the flat horizontal reflector increases the reflection of light within the lighting cover thereby minimising the loss of light while ensuring that the light source is concealed behind the lighting cover. Moreover, the longitudinal gap secures the lighting in such a way that the emitted light is not obstructed by the base.

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.

Figure 1 illustrates a lighting apparatus 100, according to an embodiment of the present disclosure. Specifically, Figure 1 illustrates different views of an assembled lighting apparatus 100, i.e., a side view (A) and a close-up view (B) of an end of the lighting apparatus 100. The lighting apparatus 100 can be termed as a batten, owing to its shape. Further, the lighting apparatus 100 may be installed on a wall or may be suspended from a ceiling. In either case, the lighting apparatus 100 may provide adequate illumination to the surrounding space. The lighting apparatus 100 of the present disclosure is a compact device that has a similar lumen output as currently used bulky batten lights. The lighting apparatus 100 has various design implements which enable a compact design while maintaining the lumen output. One of the design attributes of the lighting apparatus 100 contributing to the higher lumen output is a greater area for reflective surfaces to maximise the light emission. Details of such attributes will be explained later.

The lighting apparatus 100 may include, but is not limited to, a housing 102, a first end cap 104, a second end cap 106, and a lighting cover 108. The housing 102 forms a major portion of the lighting apparatus 100 while the first end cap 104 and the second end cap 106 are attached to either end of the housing 102. As shown in Figure 1, the housing 102 forms the bottom part of the lighting apparatus 100 while the lighting cover 108 forms the top portion of the lighting apparatus 100. The housing 102 can be made of a material, such as plastic or metal like Aluminium and may house various components of the lighting apparatus 100. For instance, the housing 102 may house a driver unit that powers a light source of the lighting apparatus 100. In addition, the housing 102 may store the wires that connects the light source to the driver unit and wires that connect the driver unit to the mains power supply. Furthermore, the housing 102 is designed to mount the lighting apparatus 100 on either wall or a mount. Accordingly, the housing 102 may include holes for the wall or a clamp for the mount. In either case, the housing 102 can be secured effectively to the wall or the mount.

In one example, the lighting cover 108 is installed on the housing 102 and forms a top portion of the lighting apparatus 100. The lighting cover 108 is made of a translucent material that diffuses the light incident thereupon. Further, the lighting cover 108 is designed to diffuse the light to spread the illumination uniformly. The first end cap 104 and the second end cap 106 are plastic pieces installed on either end of the housing 102 and are configured to protect the internal components of the housing 102. As may be understood, the first end cap 104 and the second end cap 106 are shaped to complement the ends of the housing 102 as well as the lighting cover 108. Although not shown, the first end cap 104 and the second end cap 106 may include a hole for the wires from the mains power supply to enter the housing 102.

Referring now to Figures 2 and 3 which show a detailed schematic of the lighting apparatus 100. Specifically, Figure 2 illustrates a partial view of the light apparatus 100 with the one of end cap removed while Figure 3 illustrates a detailed schematic of a cut section taken along lines 1-1 in Figure 1. The housing 102 is the bottom portion of the lighting apparatus 100 while the lighting cover 108 is installed on the housing 102 and forms the top portion of the lighting apparatus 100. Further, the housing 102 includes holes 102A adapted to receive a fastener to mount the housing on a support surface.

The lighting apparatus 100 also includes a base 202 disposed between the housing 102 and the lighting cover 108 along the length of the housing 102 and the lighting cover 108. The base 202 may be installed to support the light source 204 thereon. The light lighting cove, in one example, can be a strip of light-emitting diodes (LEDs) that may be extended along a complete length of the base 202. The base 202 further includes a pair of lips 206 along its length to secure the light source 204 thereon. The lips 206 may have an L-shaped profile that prevents dislodgement of the light source 204 due to vibrations caused during installation, uninstallation, and transport.

The base 202 may include a longitudinal slot 208 that is formed at the centre of the base 202. The longitudinal slot 208 may also extend the complete length of the base 202. The base 202 also includes a pair of horizontal reflectors 210 on either side of the longitudinal slot 208. The pair of horizontal reflectors 210 are configured to reflect the incident light towards the lighting cover 108. For instance, the pair of horizontal reflectors 210 may reflect rays (shown as bold lines) incident thereupon as reflected rays (shown as dotted lines). The horizontal reflectors 210 have a top surface 210A made of a material that reflects almost all the light incident on the horizontal reflectors 210. In one example, the horizontal reflectors 210 can be substantially flat and parallel to the bottom of the housing 102 as shown in Figure 3. Alternatively, the horizontal reflectors 210 may be inclined as shown in Figure 2. In either case, the top surface 210A of the horizontal reflectors 210 reflects the light towards the lighting cover 108 thereby minimising the loss of light and increasing lumen output.

Further, a reflection of light incident on the horizontal reflectors 210 towards the lighting cover 108 enables the reduction in the height of the lighting cover 108 which reduces the overall height of the lighting apparatus. In one example, the height of the lighting apparatus 100 is about 32 millimetres (mm) whereas the height of the lighting cover 108 is about 11.63 mm which is about 1/3rd of the height of the lighting apparatus 100. In comparison to the currently used similar-sized batten in which the height of the light diffuser is almost half the height of the batten. Thus, smaller height lighting cover 108 allows for a small size lighting apparatus 100. Accordingly, the lighting apparatus 100 of the present disclosure has a better lumen output than a currently known similar-sized batten. Moreover, the lighting apparatus 100 has the same lumen output while being compact in size as compared to a currently known same lumen output rated but bulky batten. Moreover, the shorter height of the lighting apparatus 100 makes for a sleeker design thereby enhancing the aesthetics of the lighting apparatus 100.

In one example, the light source 204 includes a substrate 212 and a luminescent portion 214 disposed on the substrate 212. The substrate 212 can be a printed circuit board (PCB) while the luminescent portion 214 can be a plurality of light-emitting diodes (LEDs). The substrate 212 may be disposed on a bottom of the longitudinal slot 208. Further, the substrate 212 is installed in the longitudinal slot 208 in such a way that the substrate 212 is completely housed within the longitudinal slot 208. In one example, the volume of the longitudinal slot is greater than the volume of the substrate and the height of the substrate 212 is less than the depth of the longitudinal slot. Moreover, the pair of lips 206 overlaps a portion of the substrate 212 to prevent dislodgement of the substrate 212 from the longitudinal slot 208. In one example, the depth of the longitudinal slot 208 is about 1.3 mm while the width of the longitudinal slot 208 is about 6.5 mm. The longitudinal slot 208 is sized to ensure that the substrate 212 is secured inside the longitudinal slot 208.

On the other hand, the luminescent portion 214 is designed to emit light for diffusion by the lighting cover 108. In one example, the top of the luminescent portion 214 is flush with the top surface 210A of the flat reflectors 210 such that a continuous flat surface is achieved. Alternatively, the top of the luminescent portion 214 is lower than the top surface 210A of the flat reflectors 210. In such configurations, the light is not directly incident on the top surface 210A. Further, a portion of light reflected by the inner walls 108A is reflected the horizontal reflector 210 and the top surface 210A reflects back the portion of light incident thereupon for diffusion by the lighting cover 108.

Alternatively, the top of the luminescent portion 214 protrudes from the longitudinal slot 208, such that a portion of light emitted by the luminescent portion 214 is incident on the horizontal reflectors 210. As a result, the horizontal reflectors 210 are able to reflect the light towards the lighting cover 108 for diffusion. In this configuration, any portion of reflected light incident on the horizontal reflectors 210 is reflected back to the lighting cover 108 for diffusion.

In either of the aforementioned scenario, the lighting cover 108 receives light from both the luminescent portion 214 as well as the horizontal reflectors 210 thereby making the complete base 202 a source of light which results in uniform illumination and consequently, uniform diffusion. Moreover, uniform illumination, also prevented the localization of the light source and the position of the luminescent portion 214 within the lighting cover is concealed. Therefore, the reduction in the height of lighting cover 108 does not reveal the position of the luminescent portion 214.

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:
