High-efficiency LED (Light-Emitting Diode) dual chip high-low beam integrated automobile headlamp module

Abstract

The invention relates to a high-efficiency LED (Light-Emitting Diode) dual chip high-low beam integrated automobile headlamp module. The high-efficiency LED dual chip high-low beam integrated automobile headlamp module comprises an LED light source, a reflection cup, a heat sink, a lens and a sleeve, wherein a locating platform for arranging the LED light source is arranged on the heat sink; the LED light source is of an upper LED light source and lower LED light source combined dual light source structure; the reflection cup is of an upper reflection cup and lower reflection cup combined dual reflection cup structure; an upper reflection cup locating platform and a lower reflection cup locating platform are respectively arranged at the upper side and the lower side of the locating platform; and a plurality of parallel fin-shaped cooling plates are arranged at the outer sides of the upper reflection cup locating platform and the lower reflection cup locating platform on the heat sink; and gaps are formed between the adjacent cooling plates. The high-efficiency LED dual chip high-low beam integrated automobile headlamp module is good in illumination effect and heat dissipation effect, high in illumination level and clear in visual field, and ensures that an automobile headlamp is in a safe and stable working environment, thus greatly improving the driving safety and prolonging the service life of the automobile headlamp.

Description

technical field [0001] The invention belongs to the technical field of automobile lighting, and in particular relates to a high-efficiency LED double-chip far and near light integrated automobile headlight module. Background technique [0002] In the prior art, the headlights of automobiles 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 The driver provides lighting. However, there are the following defects in the prior art: after the light is collected by the reflective cup, there is a defect of uneven 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 light. Spots, poor lighting effect. [0003] In addition, the interior of the car lights is a closed environment. ...

Problems solved by technology

However, there are the following defects in the prior art: after the light is collected by the reflective cup, there is a defect of uneven 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 light. Spots, poor lighting effect

[0003] In addition, the interior of the car lights is a closed environment. When the headlights of the car are in the lighting state, the closed environment where the lights are located will generate a higher temperature due to heat accumulation. Fog is generated inside, which affects the lighting effect, and it is easy to cause the parts in the car headlights to be heated and deformed, and even the parts are melted; because the heat generated by the high temperature does not flow smoothly in the closed environment, it will also cause the car The life of the electronic products inside the headlight is shortened, which seriously affects the normal use of the car headlight
