specific Embodiment 1

[0014] Specific embodiment 1: as figure 1 , 2, and 3, the headlight is composed of a bulb 1, a lamp body 2, and a lampshade 3, the lampshade 3 is a plane, and the inner surface of the lamp body 2 is composed of an upper reflective surface 4 and a lower reflective surface 5, and the reflective surfaces are all composed of a common The parabolic units of the main optical axis are connected, and the upper reflective surface is composed of upper and lower reflective surfaces. Headlights with such a structure, when low beam, can rely on the upper reflector to evenly illuminate the light emitted by the light source on the front side of the car, and will not cause glare to the other driver; Irradiate to the distance, in line with the requirements of the national standard GB4599-84.

Embodiment 2

[0015] Example 2: as figure 1 , 4, and 5, the headlight is composed of a bulb 1, a lamp body 2, and a lampshade 3. The lampshade 3 is a plane, and the inner surface of the lamp body 2 is composed of an upper reflective surface 4 and a lower reflective surface 5. The reflective surfaces are all composed of a common The parabolic units of the main optical axis are connected, and the upper reflective surface is composed of left and right reflective surfaces. The left and right reflective surfaces form an angle of α degrees, preferably 15°C. Headlights with such a structure, when low beam, can rely on the upper reflector to evenly illuminate the light emitted by the light source on the front side of the car, and can increase the low beam irradiation distance without causing glare to the other driver: , Relying on the lower irradiation mirror to irradiate the light evenly to the distance, it also meets the requirements of the national standard GB4599-84.

Abstract

The invention relates to a motor vehicle headlamp which comprises a lamp body, a lamp chamber formed by the lamp body, a light source arranged in the lamp chamber and a lamp cover arranged on the lamp chamber. The inner side of the lamp body is composed of an upper mirror and a lower mirror, the upper mirror and the lower mirror are on different curve surfaces and are respectively formed by connecting multiple reflection units, and the reflection units are paraboloids with the same principal optical axis. Light distribution is achieved through the mirrors of the lamp body, so that light distribution of the lamp cover is omitted, luminous flux of the headlamp is improved, and accordingly the headlamp has the advantages of being large in illumination range and attractive in appearance.

Description

technical field [0001] The invention relates to a motor vehicle lamp, in particular to a motor vehicle headlamp. Background technique [0002] Motor vehicle headlights are the main lighting fixtures at the front of the vehicle. They are composed of a lamp body, a lampshade, and a bulb. Generally, there are two types of beams: the low beam is used when there are other road users in front of the vehicle, so that the other party does not feel uncomfortable. The short-distance lighting beam used, the high beam is the long-distance lighting beam used when there are no other road users in front of the vehicle. The lamp body of the existing motor vehicle headlight is a reflective surface of a single structure, which passes through the lampshade. The light distribution mirror distributes the light emitted by the bulb and reflected by the lamp body to meet the lighting requirements. This structure has the following disadvantages: 1. The lighting distance is relatively short, which i...
