The LED has the advantages of energy conservation, low cost, long service life, high response speed, small element size, easy arrangement, model design and the like. The laser headlight and the LED headlight are not different, but have a great difference in technology. The laser headlight is driven in front of the laser headlight regardless of energy consumption, brightness or illumination distance. Compare with LED, the volume that laser headlight shared is littleer, and the energy consumption is lower, but the light intensity of production is more than LED by a wide margin, and the laser lamp source possesses the irradiation distance that is nearly LED high beam twice, irradiation range greatly increased.

The car light is used for the illumination usefulness at car night, and the car light generally divide into high beam and passing lamp, and the regional ratio that the high beam can shine is far away, and the passing lamp mainly is the nearly region of shining in the car traveles, consequently, carries out the switching of the far and near light of car light according to the road conditions needs of difference at the in-process of traveling. When the far and near light is switched, the switching assembly arranged in the shell of the vehicle lamp is mainly used for shading the light emitted by the lamp source, so that the far and near light can be freely switched.

However, in the prior art, the vehicle lamp has only two modes of high beam and low beam, has a single function, cannot be adjusted more according to actual road conditions, and has poor adaptability, so that the vehicle lamp which switches different light distribution modes according to the surrounding environment is urgently needed to be developed.
