该控制器按在汽车前灯电路中,会车时可自动调节前灯照度。作用距离100—150m,作用视野左右±40°,可连续调节,也可转换成非自控状态,从100～150m开始远光灯可逐渐转换成近光灯,也可闪烁。不但外形美观、控制灵敏,而且能自动控制照度,因而起到节能的 The controller is pressed in the car headlight circuit, and the headlight illuminance can be automatically adjusted when the car is in attendance. The working distance is 100-150m, and the left and right of the field of view is ±40°. It can be continuously adjusted, or it can be converted to a non-self-controlled state. From 100 to 150m, the high beam can be gradually converted to low beam or flicker. Not only beautiful appearance, sensitive control, but also automatic control of the illumination, thus saving energy
