Automobile headlamp assembly and automobile headlamp

Abstract

The invention relates to the optical field, in particular to an automobile headlamp assembly and an automobile headlamp. The automobile headlamp assembly comprises a light source, a condensing lens set and a light control lens mechanism; the condensing lens set is located between the light source and the light control lens mechanism; the light control lens mechanism comprises a reflecting surface only reflecting a light beam and an emergent surface refracting the light beam obtained after being reflected by the reflecting surface; the automobile headlamp comprises a paraboloid reflection cup and the automobile headlamp assembly, and the automobile headlamp assembly is arranged in the paraboloid reflection cup; and the light beam sent out by the light source is gathered to the reflecting surface through the condensing lens set, and the light beam reflected by the reflecting surface is refracted to the inner wall of the paraboloid reflection cup from the emergent surface and then is shot to the distance place. The automobile headlamp assembly can gather light, irradiation of the light towards one direction is facilitated, and the enough irradiation brightness is ensured. According to the automobile headlamp, uniform distribution of the light beam can be achieved, the light beam is irradiated in a long-distance manner, the light beam cannot be diverged in the long-distance irradiation, brightness is uniform, and the strength is high.

technical field [0001] The invention relates to the field of optical lenses, in particular to an automobile headlight assembly and the automobile headlight. Background technique [0002] Car headlights are an essential part of the car. The current car headlights usually use a single bulb placed at the focus of the parabolic reflector for night lighting. Since the light source has a certain size, it can be reflected by a certain size. It is difficult to effectively control the collimation of the beam behind the cup, and the divergence angle of the beam is relatively large, so there will be insufficient light at a certain distance in the distance; the current negative way is to increase the power of the bulb to solve this problem, which will affect the control and use of the system.

[0002] Car headlights are an essential part of the car. The current car headlights usually use a single bulb placed at the focus of the parabolic reflector for night lighting. Since the light source has a certain size, it can be reflected by a certain size. It is difficult to effectively control the collimation of the beam behind the cup, and the divergence angle of the beam is relatively large, so there will be insufficient light at a certain distance in the distance; the current negative way is to increase the power of the bulb to solve this problem, which will affect the control and use of the system. Life, environmental protection and safety will bring disadvantages. The more important problem is that the light intensity outside the effective lighting range will be greatly increased, which will cause great visual interference to oncoming vehicles and easily cause traffic accidents. This phenomenon is well known.

If multiple groups of light bulbs are used for lighting, although the problems of insufficient brightness and short irradiation distance can be solved, it is difficult to meet the requirements in terms of cost and appearance. The increase of the beam will inevitably lead to the increase of the divergence angle of the beam. With the continuous development of LED technology, it is believed that the LED light source with high power and small size will gradually be improved to a certain extent, but this improvement is limited after all. The huge advantages of LED light source are well known. It is widely used in automobiles at present, but there are still many technical problems in the application of headlights. Therefore, the development of LED light sources and lighting optical path systems for headlights has always been a hot spot in this field. and puzzles
