Abstract

In order to avoid a series of traffic accidents caused by improper use of high beam lamps, and to give drivers a better driving experience, an adaptive driving beam (ADB) illumination system was designed, which can actively adjust the distribution of high beam. Based on the theory of non-imaging optics, the illumination optimization design method was adopted and the area was divided reasonably by calculation to control the brightness and extinguishing of corresponding LED, so as to achieve the different types of high beam. Through tracing the light with Monte Carlo simulation method, the simulation result shows that the final result of light distribution fulfills the current only for adaptive driving beam (ADB) light distribution regulation. When all the LEDs work, the maximum illumination value is 111 lx, and the efficiency of the module optical system is 35.7%.
- high beam,
- ADB,
- LED,
- light distribution regulation
