Abstract

Compared to the important role in night driving of vehicle headlights, the dazzling and discomfort problems caused by the headlights are also not ignored. Sometimes the dazzling light is the main factor of causing traffic accidents in the night. In the paper, a novel design using irregular coating mirror to solve the dazzle problem is brought forward. As for the traditional headlamp comprised of a high beam and a low beam filament, the high beam filament causes plenty of the dazzling light. If the high beam filament's lighting density can be reduced without influencing the lighting effect, the problem is to be solved. Because plane-reflect mirror can change the light's transmitting direction, we employ the plan which uses 88 slat glasses whose upper surfaces coated with reflection films and bottom surfaces with light absorbing films, and put the whole mirror in front of the headlamp. When turn on headlight, the dazzling light is reflected by glass' upper plane, then absorbed by bottom plane. So the mirror prevents people from the dazzling light. In addition, the paper presents the experiment results to prove the anti-dazzle effect.
