Problems solved by technology

However, there are the following defects in the prior art: First, there is a defect of uneven light after the reflective cup gathers light. In the prior art, bumps are usually added to the inner surface of the reflective cup to improve the light output effect, but this structure will It leads to bright spots and poor lighting effect; secondly, the outgoing light of the existing automobile headlights is relatively scattered, and the range is short, and the lighting clarity is poor, which is likely to have a negative impact on the safety of driving
[0003] In addition, the interior of the car lights is a clos

Example Embodiment

[0055] For ease of understanding, the specific structures of each component in the present invention will be further described below with reference to the accompanying drawings.

[0056] 1. Reflector

[0057] like Figures 6 to 8 As shown, the reflector includes a reflective cup body 10, the reflective surface 14 of the reflective cup body 10 is in the shape of an ellipsoid, and the reflective surface 14 of the reflective cup body 10 is formed by an elliptical arc around the long axis a of the ellipse where the elliptical arc is located A semi-revolution surface formed by rotating 180°; the ellipse arc is the arc segment enclosed by the long axis a and the short axis b of the ellipse in the same quadrant.

[0058] like Image 6 As shown, the reflective surface 14 of the reflective cup body 10 is also the inner wall surface of the reflective cup body 10 .

[0059] In the reflector of the present invention, the length ratio between the major axis a and the minor axis b of the...

Abstract

The invention belongs to the technical field of automobile illumination, and particularly relates to an LED (light emitting diode) automobile headlamp high beam optical module, which comprises an LED light source, a reflector, a lens and a heat radiator, wherein a platform is arranged on the grid-shaped heat radiator, the heat radiator is connected with a base through a ball head connecting mechanism and a position regulating structure, the LED light source is arranged at a hollow part position of the reflector, in addition, the LED light source is connected with the platform, the reflector comprises a reflecting cup body, the reflecting surface of the reflecting cup is in an ellipsoidal surface shape, the lens comprises a planar incident surface allowing light rays to enter the lens, and also comprises an outer convex surface allowing the light rays to be emitted out, the outer convex surface is in an ellipsoidal surface shape, and the lens is fixedly arranged on the heat radiator through a lens support frame. The module has the advantages that the illumination effect is good, the illumination degree is high, the view sight is clear, a good heat radiation effect is also realized, and an automobile headlamp is enabled to be in a safe and stable work environment, so the running safety is greatly improved, and the service life of the automobile headlamp is prolonged.

Description

technical field [0001] The invention belongs to the technical field of automobile lighting, and in particular relates to an LED automobile headlamp high beam optical module. Background technique [0002] In the prior art, automobile headlights generally use reflectors to focus light, and the light after being concentrated by the reflector cups is used to focus again with a lens when it exits, so that the light in front of the car reaches a certain illuminance value, thereby providing a better environment for driving. Personnel provide lighting. However, there are the following defects in the prior art: First, there is a defect of uneven light after the reflective cup gathers light. In the prior art, bumps are usually added to the inner surface of the reflective cup to improve the light output effect, but this structure will Lead to bright spots and poor lighting effect; second, the outgoing light of the existing automobile headlights is relatively scattered, and the range i...
