Description

TECHNICAL FIELD

The present disclosure relates to the technical field of automobile lamps, and in particular, to a new automobile LED headlamp.

BACKGROUND

Automobile LED headlamps generally refer to the front headlights, which are lighting devices installed on both sides of the head of a car for illuminating the road during night driving. The automobile LED headlamps use LED light sources, which not only saves energy, has high luminous efficiency and low energy consumption, but also is environmentally friendly, and meets the current social requirements. As the “eyes” of a car, the automobile LED headlamps not only relate to the external image of a car owner, but also has close relation to the safe driving at night or in bad weather conditions.

The heat dissipation performance of the automobile LED headlamps is one of the important factors affecting their service life. Therefore, heat sinks are usually installed on the automobile LED headlamps to improve the heat dissipation performance of the headlamps. However, the current heat sinks installed on the automobile LED headlamps generally have poor heat conduction and heat dissipation effects. Moreover, the structural design is not reasonable enough and the degree of integration is low, resulting in a relatively large space occupied by the lamp body. Therefore, there is an urgent need for improvement.

The LED lamp body is provided on both sides of the metal lamp holder. The LED lamp body is connected with the metal lamp holder by bolts. The heat sink is fixed at one end of the metal lamp holder and the heat sink is internally provided with an arc-shaped groove. The heat dissipation fins are evenly distributed on an outer wall of the heat sink. The heat dissipation fins are fixedly connected with the heat sink. The heat-conducting tube structure is provided on one side of the metal lamp holder.

Preferably, the heat sink is of an arc-shaped structure, which optimizes the structure of the heat sink.

Preferably, a base is fixed at one side of the heat sink away from the metal lamp holder, which facilitates the installation of a heat dissipation fan.
