Embodiments of the present invention relate to automotive lighting systems and more particularly to a bracket for arrangements of PCBs with a single reflector in vehicle headlamp assembly.
BACKGROUND OF THE INVENTION
With the advancement of technology, the design and features of the headlamp also improve. The traditional bulbs and/or HIDs as a light source are being replaced by the LEDs in the vehicular headlamps. LEDs provide more illumination and consume less power than the previously used light sources. The LED lamps use multiple electronic circuits for the generation of High beam and low beam. The different functions of LED lamps require different PCBs. The PCBs are mounted at different places for the different functions. Further, vehicular LED lamps have two configurations i.e., low-beam and high beam. For producing a lower beam of light, higher beam of light, positioning light and signal different reflectors are required. The arrangement of reflectors requires more tools. The requirement of more tools adds more cost to the design of the vehicular headlamps.
The arrangement of multiple electronic circuits for the different PCBs and different reflectors for the low beam, high beam configuration and positioning configuration requires more space. The traditional design also requires more screws for fastening the PCBs and reflectors at different places. The use of more space and number of screws make the vehicular headlamps bulky and also increase the complexity in the circuit design of the headlamps. The use of more screws & more tools for mounting the PCBs assembly and reflectors also increases the assembly time. The increase in assembly time will cause-effect in productivity. The design of traditional headlamp is complex, time-consuming, costly and bulky.
Therefore, there is a need in a bracket for arrangements of PCBs with a single reflector in vehicle headlamp assembly, that does not suffer from above-mentioned deficiencies and provides an effective and viable solution.
