Abstract

Abstract:

In order to solve the problem of car driving safety at night under complex road conditions and avoid the dazzling effect of the drivers of the opposing vehicle when meeting cars, the study is based on the non-imaging theory and combined with the law of refraction and reflection to establish the corresponding projection relationship between the emitting light of LED and the far-light distribution point on the receiving surface. The discrete points of the free-form surface are solved by numerical iteration, and are imported into 3D software for fitting modeling. A reflective adaptive driving beam optical system is designed to combine and form different high beam types by controlling the on and off of the corresponding LEDs. The test results of the final sample show that when the optical system is in the maximum working condition, the luminous efficiency reaches 34.3%, and the maximum illuminance value is 134 lx, which demonstrates that the light distribution results meet the requirements of high beam regulations.

Key words: non-imaging optics, freeform surface reflector, adaptive driving beam, light distribution regulation, LED, automobile headlamp, ultra-precision machining, freeform surface measurement
