Problems solved by technology

[0003] The heat dissipation methods of LED headlights in the prior art are mainly divided into natural air cooling, forced air cooling and forced liquid cooling. Natural air cooling needs to provide a large enough space for the radiator because of the large area required for heat dissipation. Complicated working environment is not suitable, so the cooling effect of LED headlights by natural air cooling is poor; forced air cooling is to add a fan behind the LED lamps to dissipate heat, which will affect the stability of the lamp work; forced liquid If it is cold, it is necessary to add water pipes and water pumps to the LED lamps, which is inconvenient to install and less stable.
[0004] Moreover, the LED headlights of the prior art mainly use free-form surfaces for reflection, so that the light distribution system will be divided into many small parts during work, and each small part completes the reflection requirements of a part of the light pattern, so the required processing accuracy High, high processing cost, and difficult

Abstract

The invention relates to the technical field of LED lamps, in particular to an automobile LED headlamp. The automobile LED headlamp comprises a lamp shell and a lampshade. A high-beam lamp unit (1), a low-beam lamp unit (2) and a steering lamp unit (3) are arranged between the lamp shell and the lampshade; and the low-beam lamp unit and the high-beam lamp unit are subjected to heat dissipation through a heat dissipation tube and a three-layer sticking structure. The automobile LED headlamp is simple in structure, better in heat dissipation effect and convenient to machine.

Description

technical field [0001] The invention relates to the technical field of LED lamps, in particular to an automobile LED headlamp. Background technique [0002] LED has many advantages such as energy saving, high efficiency and environmental protection, and has been more and more widely used in general lighting in recent years. With the rapid development of the automobile industry and the continuous improvement of LED light efficiency, the application of LEDs in automobiles is becoming more and more common, including interior lighting, brake lights, tail lights and headlights. Because LED headlights need to use high-power LED lights, the need for heat dissipation has become a prominent problem. [0003] The heat dissipation methods of LED headlights in the prior art are mainly divided into natural air cooling, forced air cooling and forced liquid cooling. Natural air cooling needs to provide a large enough space for the radiator because of the large area required for heat dissi...
