The present disclosure relates generally to the field of automotive industry, and particularly, the present disclosure relates to a lighting assembly for vehicles.
BACKGROUND OF THE INVENTION
Lighting assemblies have been conventionally known to be used in vehicles, for illuminating space around the vehicle. The lighting assemblies can be tail lamps, indicators, head lamps, etc. The automotive lighting assemblies uses LEDs or halogen as light sources and also includes sensors, etc to assist the operation of the light assemblies. Generally, the aforementioned components are housed in a housing and some of the components, such as the lens, back plates are welded to the housing. Conventionally the components may be joined by ultrasonic welding, vibration welding, etc. which may not be leak proof, thereby causing seepage of water into the lamp and interfering functioning of various components inside the housing. Further, the LEDs may short circuit due to ingress of water resulting in damage to the light assembly.
To overcome some of the problems and shortcoming of the conventional art, there is a need for developing a lighting assembly for vehicles which is leak proof.
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.

The present disclosure relates to a lighting assembly for illuminating a path ahead of a vehicle wherein such a light assembly is installed. Figures 1 and 2 illustrate a lighting assembly 100 according to the present disclosure. Specifically, Figure 1 illustrates a perspective view of the lighting assembly 100. Figure 2 illustrates a sectional view of the lighting assembly 100. Specifically, the lighting assembly 100 includes a housing 102, a lens 122, a light source (not shown), a back plate 128, a first wall 116-1, a second wall 116-2 and a plurality of ribs 108.
The housing 102 is adapted to support and hold the reflector 118, the lens 122, a wire harness assembly (not shown), and has a first side 102-1 and a second side 102-2. In one example, the housing 102 may be made up of polycarbonate-acrylonitrile butadiene styrene and black plate acrylonitrile butadiene styrene. The lighting assembly 100 includes one or more air vent 112 formed on a housing wall 130. The air vents 112 extend towards an exterior of the housing 102 and are adapted to regulate airflow in and out of the lighting assembly 100.
In an example, one or more cut out 110 is provided on the first side 102-1 of the housing 102, and seat 114 on the second side 102-2 of the housing 102. Further, the lens 122 is mounted on the cut out 110 and is adapted to disperse light rays from the light source installed in the housing 102. The cut outs 110 have predefined size and are placed in a relative orientation to ensure that the lens 1222 is installed in a desired orientation. The cut outs 110 also prevent interchanging of the lens 122. In one example, the lens 122 is a transparent polycarbonate lens and the light source may be an LED light, or any other type of light source installed as per requirement. Further, the lens 122 may be coloured depending on the application of the lighting assembly 100. In one example, the transparent polycarbonate lens may be used for a lighting assembly 100 installed at a front position of a vehicle (not shown). In another example, a polycarbonate amber lens may be used in a lighting assembly 100 being used as an indicator light in the vehicle. In yet another example, a polycarbonate red lens may be used in a lighting assembly 100 being used as a tail lamp, stoppage indicator, USA blinker, etc. in the vehicle. The lens 122 protects the first side 102-1 of the housing 102 from water, dust, mud, and environmental temperatures, thereby protecting the light assembly

100 from front. In one example, the lens 122 may be attached with the first side 102-1 of the housing 102 into the at least one cut out 110 by a fastener. The lens 122 may be further fixed to the first side 102-1 of the housing 102 by vibration welding. In another example, the lens 122 may be joined with the first side 102-1 of the housing 102 by any type of welding as per feasibility and requirement. In one embodiment, the lens 122 includes a plurality of slots 124 around the at least one cut out 110, adapted to lock the lens 122 thereon in a predefined orientation.
In one embodiment of the present disclosure, the back plate 128 is attached to the second side 102-2 of the housing 102 and is adapted to be installed into the seat 114 by ultrasonic welding. Figures 3 and 4 depict the lighting assembly 100 with the back plate 128 attached to it. Specifically, Figure 3 illustrates atop view of the lighting assembly 100 with the back plate 128 attached to it. Specifically, Figure 4 illustrates a sectional view of the lighting assembly 100 with the back plate 128 attached to it. Further, Figure 5 specifically illustrates a schematic view of the back plate 128. In one example, the back plate 128 may be made up of Acrylonitrile Butadiene Styrene (ABS), or any other material as per the requirement and the application. Further, the back plate 128 protects the housing 102 from water, air, mud, dust, moisture, etc. from second side 102-2, thereby protecting the lighting assembly 100 from back side. The back plate 128 includes a hole 128A to pass the wire harness assembly therethrough. A first wall 116-1 is provided within the housing 102 on the second side 102-2 of the housing 102. The first wall 116-1 is adapted to support a first edge 114-1 of the seat 114. Similarly, the second wall 116-2 is provided within the housing 102 on the second side 102-2 of the housing 102. The second wall is adapted to support a second edge 114-2 of the seat 114. The plurality of ribs 118 is disposed on the first edge 114-1. The ribs 118 are adapted to reinforce the first wall 116-1 and an ultrasonic weld between the first wall 116-1 and the seat 114. Similarly, ribs 118 are disposed on a second edge 114-2 of the seat 114 to reinforce the second wall 116-2 and the ultrasonic weld between the second wall 116-2 and the seat 114. The ribs 118 support the first wall 116-1, the second wall 116-2 and provide distribution of force experienced by the walls 116-1, 116-2 from the housing wall 130, and the force dissipated during welding.

Further, the ribs 118 support the housing wall 130 from bottom, thereby avoiding the housing wall 130 from bending.
In one embodiment, the housing 102 is adapted to carry the reflector 118 (not shown). The reflector 118 is one of the main parts of the light assembly 100 and is adapted to deviate light from the light source inside the housing 102 towards the front side of the light assembly 100 towards a path to be illuminated by the light assembly 100. In one example, the reflector 118 may made up of a polycarbonate-black and aluminium metalizing is done on an optical surface of the reflector 118.
The lighting assembly 100 disclosed herein is easy to assemble. Further, the plurality of ribs 118 assures extra support to the first wall 114-1 and the second wall 114-2, thereby enhancing strength of the ultrasonic weld. Furthermore, the back plate 128 includes a hole 128A to pass electrical cables therethrough, thereby enabling easy wire harness routing.
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.
