设计注意事项

A headlight in a car has a number of lights including high beam, low beam, cornering light, daytime running light, position light, turn signal, side marker and fog lights. The light sources used for these lights could be incandascent bulbs, xenon lamps and high brightness Light Emitting Diodes (LEDs). The high beam and low beam could be fixed in position thus causing the beam patters to be fixed. Or high beam and low beams lights could be adaptive beams in order to adapt to the road conditions. Adaptive front lighting (AFS) and Adaptive Driving Beam (ADB) are achieved using motors to swivel the light or LED matrix managers to turn on and off certan sections of the light.
