Automobile headlamp structure — light distribution mirror

It plays a protective role for the whole headlamp assembly. The beam formed by the light source of the automobile headlamp through the reflector is difficult to meet the requirements of laws and regulations for the headlamp. The light distribution mirror is also required to change, widen or narrow the beam, so as to form the required lighting in front of the vehicle. This function is completed by the headlamp distribution mirror (headlamp glass). The headlamp lens is composed of many uneven small prisms. It can refract and scatter the light reflected by the reflector to meet the light distribution requirements of the headlamp. At the same time, it also diffuses part of the light to both sides, so as to broaden the lighting range of the headlamp in the horizontal direction and obtain the desired light distribution effect. Some automobile headlamps only rely on the special structure, complex shape and high processing accuracy of the reflector to meet the light distribution requirements, but the design, calculation, die accuracy and processing technology of producing this kind of reflector are still very difficult.

The illumination effect of light also depends on the illumination angle to a certain extent, and the light adjusting device can give full play to its maximum potential.
