The present disclosure relates to lighting devices and more particularly, to a universal lighting device for vehicles.
BACKGROUND
With the ever-growing traffic on roads, it is relevant to ensure safe driving conditions. In fact, in the recent past, significant growth and development are witnessed in the field of automotive lighting focusing towards the safety of the drivers. Automotive lights, such as lamps, play a major role in providing visibility to a vehicle on road, particularly, during the night. Various types of lamps are nowadays available in the market for different vehicles. Various types of lamps, such as tail lamps, stop lamps, parking lamps, and blinker lamps, are employed in the vehicle for performing different illuminating functions. Such lamps usually comprise a reflector and a light source to achieve optimal illumination and light distribution.
However, constructional aspects of the reflector vary based on the type of lamps in which such reflector is needed to be employed. Also, operational and constructional aspects of the reflector are needed to be optimized in order to comply with homologation requirements of different countries. Therefore, reflectors for different types of light and different homologation requirements are manufactured separately which results in a substantial increase in the overall manufacturing cost of the lamps. Further, existing lamps are employed with a light source, such as a bulb, which acquires larger space within a compartment of the lamp. Therefore, such lamps require a larger mounting space on the vehicle. Further, existing lamps fail to provide uniform illumination and consume higher electrical power.
From the above, it may be gathered that there exists a need for a universal lighting device that can be employed in the vehicle for achieving different illuminating functions and also complies with different homologation requirements.

For example, a PCB assembly for indicating turn signal and a PCB assembly for indicating a stop light can be fastened to the reflector 218 without incorporating any substantial alterations in a structure of the reflector 218. Therefore, the reflector 218 may be adapted to support the different types of PCB assemblies.
Referring to Figure 4b, the supporting portion 402 may include an inner surface 402-1 and an outer surface 402-2. The outer surface 402-2 may be adapted to removably support the PCB assembly 216.

the PCB assembly 216 may be removably fastened to the outer surface 402-2 of the supporting portion 402 in a manner that the plurality of light source 502 may accommodate in the plurality of slots 402-3.
Referring to Figure 4b and Figures 5a-5d, the optical portion 404 may be positioned adjacent to the supporting portion 402. The optical portion 404 may be adapted to reflect light beams emitted from the plurality of light sources 502. The PCB assembly 216 may be mounted on the supporting portion 402 in a manner that each of the plurality of light 502 oriented in a direction towards the optical portion 404 of the reflector 218. The optical portion 404 may include an inclined surface 404-1 having an optical element adapted to reflect light beams emitted from the plurality of light sources 502. A slope of the inclined surface 404-1 may gradually increase in a direction away from the supporting portion 402 of the reflector 218.
In an embodiment, the housing assembly 214 may include an air vent positioned on a bottom surface of the housing assembly 214 and facing a lower surface of the reflector 218 disposed within the housing assembly 214.

Further, the lens 212 may be adapted to be removably coupled to the housing assembly 214. The lens 212 may be adapted to conceal the reflector 218 of the lighting device. In particular, the lens 212 may be positioned with respect to the reflector 218 in a manner that the reflected light beams from the reflector 218 may be directed towards the lens 212. In an embodiment, the lens 212 may be adapted to be replaced based on atype of the lighting device 100. As explained earlier, the type of the lighting device 100 may include the tail light, the front light, the blinker light, and the stop light of the vehicle.
For instance, an amber-colored lens may be coupled to the housing assembly 214 in order to employ the lighting device 100 as the blinker light.

In yet another instance, a colorless lens may be coupled to the housing assembly 214 in order to employ the lighting device 100 as the front light.

Figure 7 illustrates an assembling process of the universal lighting device, according to an embodiment of the present disclosure. Referring to Figure 7, at step 702, the reflector may be metalized by performing a manufacturing process. At step 704, a support bracket may be coupled to the reflector with a plurality of screws. Further, at step 706, the PCB assembly 216 may be fastened to the reflector 218 with a plurality of screws and a plurality of nylon washers. Thereafter, at step 708, the PCB assembly 216 may be positioned within the housing assembly 214 and subsequently, electrical wiring may be connected to the PCB assembly through the housing assembly 214. At step 710, the lens 212 may be coupled to the housing member 214 in a manner that the lens 212 conceals the optical portion 404 of the reflector 218.
As would be gathered, the universal lighting device 100 of the present disclosure can be employed for achieving different illuminating functions without altering constructional aspects of the reflector 218 of the universal lighting device 100. Further, illumination generated by the universal lighting device 100 complies with homologation requirements of different countries. In particular, without altering constructional aspects of the reflector 218, the universal lighting device 100 can comply with the homologation requirement of different countries. Further, the lighting device 100 includes the PCB assembly 216 provided with the plurality of light sources 502, such as LEDs, adapted to project light beams on the reflector 216. Implementation of LEDs as the light source substantially reduces the overall size of the universal lighting device 100.
Further, as explained earlier, the reflector 218 includes the optical portion 404 having the inclined surface 404-1 with the slope which gradually increases in a direction away from the supporting portion 402 of the reflector 218. Such constructional details and arrangement of the reflector 218 results in uniform illumination from the universal lighting device 100 and also reduces the overall power consumption of the universal lighting device 100. Therefore, the present disclosure offers the universal lighting device 100 that is efficient, economical, compact, flexible, and effective for the vehicle.
