Problems solved by technology

The existing headlights are not universal, and are often produced separately for different positions of the headlights, thereby increasing production and maintenance costs. At the same time, the existing headlights also have no position structure. When the position adjustment is required, professional personnel to adjust, and the position is often not uniform, which often affects the light distribution of the headlights

Abstract

The invention is suitable for the technical field of lighting, and provides a headlamp reflector and a motor vehicle headlamp. The headlamp reflector comprises first light reflecting cup, a second reflecting cup and a third reflecting cup which are respectively composed of four freedom curved surfaces which are established on parabola datum planes of different focal distances through splicing, the curvatures of the freedom curved surfaces on different positions of the reflecting cups approach to the corresponding datum plane parabola curvature, and the curvatures of the respective curved surface are not equal; and a heat dissipation piece in the motor vehicle headlamp is provided with a reflector, by virtue of the different conjugations of multiple fixing holes arranged on the heat dissipation piece and a connecting hole arranged in a lamp body, the position adjustment of the reflector is realized, and the light distribution requirement is achieved. According to the invention, the motor vehicle headlamp has universality, an installation position and an installation manner of headlamp are changed, the position control of the reflector is easy to realize, and the light distribution effect of the headlamp is basically not influenced.

Description

technical field [0001] The invention belongs to the technical field of lighting, and more specifically relates to a headlight reflector and a motor vehicle headlight including the headlight reflector. Background technique [0002] The headlights are installed on both sides of the heads of automobiles, engineering vehicles, tanks, etc., and are used for road lighting when driving at night. Especially for the headlights of tanks and engineering vehicles used by troops, in order to meet the light distribution requirements of different operations, different installation methods or installation positions are often used, such as horizontal installation, vertical installation or panel installation, to be used as The left headlight, right headlight or front upper headlight, the different installation positions and installation methods of the headlights determine the different installation positions of the internal reflectors, which need to be adjusted. The existing headlights are n...
