[0030] like Figures 1 to 7 As shown, an ADB high-beam optical system comprises: a reflector 1, wherein the reflector 1 has a first focus 2, and the first focus 2 is located inside the reflector 1; a light-transmitting member 3, wherein the light-transmitting member 3 has a second focus 4, and the light-transmitting member 3 comprises a light-entering portion 5 and a light-emitting portion 6, wherein a straight line in a horizontal plane that is perpendicular to a final light-emitting direction and passes through the first focus 2 is defined as a second straight line, the light-entering portion 5 is a rotation surface formed by rotating a section of an outer contour surface of a cylindrical lens in a horizontal plane around the second straight line, the light-entering portion 5 has a first curvature 7 in the horizontal plane for collimating light emitted from the second focus 4, the light-emitting portion 6 is a stretching surface formed by stretching a section of an outer contour surface of the cylindrical lens in a vertical plane along the normal of the section, and the light-emitting portion 6 has a second curvature 8 in the vertical plane for collimating light emitted from the second focus 4; a light-emitting member 9, wherein the light-emitting member 9 is a light source, and light emitted by the light source is irradiated to the first focus 2.
[0031] It should be noted that: in a plane parallel to the light emitting direction, the light emitted by the light source enters the light transmitting member 3 after being reflected by the reflective member, and in the horizontal plane, the incident light is collimated in the horizontal plane by the first arc 7 of the light input portion 5 to form parallel light in the horizontal plane. At the same time, in the vertical plane, the incident light passes through the second arc 8 of the light output portion 6 to collimate the incident light in the vertical plane to form parallel light in the vertical plane. After being collimated in the vertical plane and the horizontal plane at the same time, parallel outgoing light is formed, and finally the ADB high beam light type of a single pixel is formed.
[0032] Preferably, the reflector 1 has a reflective surface 10 formed by stretching a parabola, and the first focus 2 is located inside the reflector 1 . Specifically, the light emitted by the light source irradiates the first focus 2 and is reflected to the light-transmitting member 3 through the reflective surface 10 .
[0033] Preferably, the reflectors 1 and the light-emitting elements correspond one to one, there are a plurality of reflectors 1 and light sources, any straight line in the horizontal plane is defined as the first straight line 11 , and the plurality of reflectors 1 and light sources are arranged along the direction of the first straight line 11 .
[0034] Preferably, the reflectors 1 and the light-emitting elements correspond one to one, and there are a number of reflectors 1 and light sources. Any straight line in the horizontal plane is defined as the first straight line 11. The reflectors 1 and light sources are arranged in two rows along the direction of the first straight line 11, and the reflective surfaces 10 of the two rows of reflectors 1 are arranged back to back.
[0035] Specifically, there are a number of light-transmitting elements 3, each of which corresponds to a number of reflective elements 1 and light sources, and forms a part of the ADB high-beam light pattern. The light-transmitting elements 3 are arranged in two rows along the direction of the first straight line 11, and finally form a complete ADB high-beam light pattern.
[0036] Preferably, optical patterns are provided on the light entrance portion 5 and the light exit portion 6 to achieve more uniform light distribution, increase the angles of light diffusion up and down and left and right, and improve the light type and color.
[0037] To sum up, an ADB high beam optical system of the utility model is formed by setting a light source, a reflective element 1 and a light-transmitting element 3, and the above three are grouped and arranged arbitrarily along a first straight line 11 in a horizontal plane to form a complete optical system, and finally form a complete ADB high beam light pattern. Compared with the ADB optical system in the prior art, the ADB high beam optical system of the utility model has a simpler structure. On the premise of meeting the light pattern requirements, the structure of the ADB high beam system is greatly simplified, the volume of the headlight module using the utility model is further reduced, and the size of the opening in the upper and lower directions of the headlight is reduced, which can better adapt to the development trend of flattening of headlight shapes.
