Microcontroller Based High Brightness LED Lighting Control for Hybrid Vehicles

Automobile manufactures have been rapidly switching to LED headlights because
they perform better than conventional halogen headlamps in terms of luminous flux
and energy efficiency. To ensure optimal luminous flux and long operating life, LED
headlights require an effective driver that can operate over a wide range of input and
output voltage and provide immunity to automotive electrical transients. The intent of
this project is to come up with a small size and cost effective universal driver using
digital power control of switch mode power supply. To develop a better enhanced
model, different existing models will be studied. Finally, design considerations from
the study will be analysed. A laboratory prototype will be designed and tested to verify
the feasibility.
