Problems solved by technology

Although this technology achieves the light distribution requirements, it has the following disadvantages: 1. Only half of the light energy is used, that is, only the upper hemisphere or the lower hemisphere; 3. It is difficult to process two ellipsoids together, and it is difficult to process the seam into an ideal effect; 4. The condensers of motor vehicle headlights are all convex condensers. The imaging quality is poor, and the same light-gathering ability is large in size and heavy in quality.

Abstract

The invention relates to a lamp, particularly a motor vehicle headlight. The motor vehicle headlight comprises a mirror reflector, a light source arranged inside the mirror reflector, a collecting mirror arranged in front of the mirror reflector, a baffle arranged between the mirror reflector and the collecting mirror, and a low beam horizontal refraction column lens arranged the optical axis from the end face to the focus of the mirror reflector. The motor vehicle headlight has the advantages that a rotating ellipse single-curved surface mirror reflector replaces two or more curved surface mirror reflector, thereby simplifying processing techniques, improving processing quality, ensuring processing accuracy, increasing reflecting power of the mirror reflector and increasing the utilization rate of luminous energy; the headlight can meet the standard of being wide horizontally and narrow vertically, thereby extending the lighting range of low beam of the motor vehicle headlight, doubling the illuminating brightness of the low beam; and low beam lighting can utilize all light energy so as to the power of the light source when the same illuminating brightness is reached, thereby achieving the effect of energy conservation and emission reduction.

Description

technical field [0001] The invention relates to a lighting lamp, in particular to a motor vehicle headlight. Background technique [0002] The national standard has strict requirements on the light distribution of motor vehicle headlights, and is limited by the national standard, such as: the illuminated range of the low beam lighting area is required to expand very wide in the horizontal direction and narrow in the vertical direction; In the high beam lighting area, light energy is required to be concentrated in the central area. [0003] At present, the light distribution of lighting lamps used in the market is far from meeting the requirements of light distribution standards, and most of them are high-power lighting lamps. The light source of the halogen tungsten lamp produced by German HELLA company is realized by the metal reflector. The reflector is spliced ​​by two half ellipsoids with different curvatures. Since the parameters of the two half ellipsoids are differen...
