Description

机动车前照灯 技术领域  Motor vehicle headlights
本发明涉及照明灯， 尤其涉及一种机动车前照灯。  The present invention relates to a lighting lamp, and more particularly to a motor vehicle headlight.
背景技术 Background technique
国家标准对机动车前照明灯的配光做了严格的要求， 并以国家标准的方式 加以限定， 如： 近光照明区被照明的范围， 要求水平方向扩展的很宽， 垂直方 向很窄； 远光照明区， 则要求光能量集中在中心区。  The national standard imposes strict requirements on the light distribution of motor vehicle front lighting, and is limited by national standards. For example, the range of illumination of the low-light illumination area requires a wide horizontal extension and a narrow vertical direction; In the high beam illumination area, the light energy is concentrated in the central area.
目前市场上使用照明灯配光远达不到配光标准要求， 而且多半是大功率的 照明灯。以德国 HELLA公司生产的卤钨灯的光源实现机动车照明的灯是由金属 反光镜实现的， 该反光镜是由两个不同曲率的半个椭球拼接成， 由于两个半椭 球参数不同， 光源所发出的光经椭球面反射后， 在某个截面上， 有一个符合设 计要求的分布， 再经聚光镜投影后， 达到机动车前一定距离实现配光要求。 曲 率小的半椭球为近光照明， 曲率大的半椭球为远光照明。近光照明为常开状态， 远光由挡板控制幵关。 虽然该技术实现了配光要求， 但是存在以下缺点： 1、 光 能只利用了一半， 即只有上半球或下半球； 2、 两个椭球接缝处宽， 表面不规则 形成不能利用的杂光， 更加降低了光能的利用率； 3、 两个椭球接到一起加工难 度大， 很难将接缝处加工成理想的效果； 4、 机动车前照灯的聚光镜均为凸聚光 镜， 成像质量差， 同样聚光能力体积大、 质量重。  At present, the use of illumination lamps on the market is far from the standard of light distribution, and most of them are high-power lamps. The lamp for realizing the illumination of a motor vehicle with a light source of a tungsten halogen lamp produced by HELLA of Germany is realized by a metal mirror which is formed by splicing two half ellipsoids of different curvatures, due to different parameters of the two semi-ellipsoids. After the light emitted by the light source is reflected by the ellipsoidal surface, on a certain section, there is a distribution that meets the design requirements, and after being projected by the condensing mirror, the light distribution requirement is achieved at a certain distance in front of the motor vehicle. The semi-ellipsoid with small curvature is low beam illumination, and the semi-ellipsoid with large curvature is high beam illumination. The low beam illumination is normally open, and the high beam is controlled by the bezel. Although this technology achieves the light distribution requirements, it has the following disadvantages: 1. The light energy is only used in half, that is, only the upper hemisphere or the lower hemisphere; 2. The joints of the two ellipsoids are wide, and the surface irregularities are formed to be unusable. Light, the utilization rate of light energy is further reduced; 3. It is difficult to process two ellipsoids together, and it is difficult to process the joint into a desired effect; 4. The condensing mirrors of the motor vehicle headlights are convex concentrating mirrors. The image quality is poor, and the same concentrating ability is bulky and heavy.
