When the high beam function is provided, the low beam LED light source 111 and the high beam LED light source 121 are simultaneously turned on, the high beam LED light source 121 emits light to form a first light beam through the high beam reflector 4, the low beam LED light source 111 emits light to form a second light beam through the low beam reflector 3, and the two light beams are distributed and superposed to form a high beam through the lens 21; those skilled in the art will appreciate that the low beam LED light sources 111 may also be inactive, with only the high beam LED light sources 121 operating. But this provides a high beam range and brightness that is less than that provided by the low beam LED light sources 111 operating simultaneously. In the present embodiment, when providing the high beam function, the low beam LED light source 111 and the high beam LED light source 121 are simultaneously turned on.

When the low beam function is provided, the high beam LED light source 121 does not work, the low beam LED light source 111 is turned on, the low beam LED light source 111 emits light to form a light beam through the low beam reflector 3, the light beam forms a light beam with a bright-dark cut-off line through the cut-off line forming plate 52 on the bright-dark cut-off line forming assembly 5, the light beam forms a low beam light beam through the lens 21, meanwhile, the low beam reflector 3 reflects a small part of the light beam to supplement the light to the dark area in the low beam light beam through the light supplementing plate 51, so that the dark area with low beam distribution is supplemented with light without setting a characteristic structure on the lens 21, and the requirement of the standard on the brightness of eight points in the low beam iii area can be met.

Further, the cut-off line forming plate 52 includes a first segment surface 521, a second segment surface 522, and a third segment surface 523, the first segment surface 521, the third segment surface 523 being parallel to the horizontal H-H line of the reference axis, the third segment surface 523 being higher than the first segment surface 521, so that the second segment surface 522 connected between the first segment surface 521 and the third segment surface 523 is inclined at a set angle for forming a 15 ° or 45 ° rising area in the low beam distribution.

Further, the light supplement plate 51 is a transparent plastic member, the top of the light supplement plate is contoured on the bottom surface of the cut-off line forming plate 52, and when the cut-off line forming plate 52 is disposed on the top of the light supplement plate 51, the bottom surface of the cut-off line forming plate 52 is attached to the top surface of the light supplement plate 51.

The 120-degree light-emitting angle is the largest light-emitting angle of the LED light source, when a dipped beam light is provided, the dipped beam LED light source 111 works, because the end surface (namely, the light-entering end) of the light supplement plate 51 facing the dipped beam LED light source 111 is lower than the light-emitting angle, so that the direct light of the dipped beam LED light source 111 cannot directly enter the light supplement plate 51, however, the light entering the light supplement plate 51 from the end surface is only a small part of the light reflected by the dipped reflector 3 and can just enter the light supplement plate 51 from the end surface, and the part of the light comes out from the light supplement plate 51 facing the end surface (namely, the light-emitting surface) of the lens 21, and eight points in the iii area are complemented by the part of the light, so that the complementary light can be well prevented from being over-bright.

Specifically, the cut-off line forming plate 52 is formed by stamping stainless steel with double mirror surfaces, and light reflected by the low-beam LED light source 111 through the low-beam reflector 3 can be reflected again through the top surfaces of the double mirror surfaces, so that the effective utilization rate of light emitted by the low-beam LED light source 111 is further improved; the light reflected by the high beam LED light source 121 through the high beam reflector 4 can be reflected again through the bottom surface of the double mirror surface, so as to further improve the effective utilization rate of the light emitted by the high beam LED light source 121.
