Automobile LED headlamp cooling structure

Abstract

The invention discloses an automobile LED headlamp cooling structure. The automobile LED headlamp cooling structure comprises a structural body and LED lamp beads; a base is fixed to the upper end ofthe structural body; an LED lamp column is fixed to the middle position of the upper surface of the base; a fixed plate is welded to the bottom face of the base; screw holes penetrate the two sides ofthe fixed plate; fixing screws are inserted in the screw holes in a penetrating manner; a cooling box is fixed at the lower end of the fixed plate; a plurality of cooling holes penetrate the surfaceof the cooling box; a driving device is connected to the upper end of the right side of the cooling box; a plug is connected to the upper end of the driving device; and a plurality of cooling aluminumbelts are arranged in the cooling box. According to the automobile LED headlamp cooling structure, the driving device drives a cooling draught fan to run at the same time while the cooling aluminum belts are used for dissipating heat generated when the LED lamp beads run, the remaining heat is dissipated out through cooling holes, the cooling efficiency of the automobile LED headlamp cooling structure is further improved, the automobile LED headlamp cooling structure is applicable to production and use, and good development prospects are achieved.

Description

technical field [0001] The invention relates to the technical field of LED headlights, in particular to a heat dissipation structure of an automobile LED headlight. Background technique [0002] Car headlights are car headlights. Headlights are lighting fixtures that are used to identify the front view when driving at night. They are symmetrically installed on both sides of the front of the vehicle. LED is an electroluminescent device that uses solid semiconductor chips as Luminescent materials, through the recombination of carriers, cause photon emission and directly emit light. LED headlights are lighting appliances manufactured using LEDs as light sources. [0003] In the existing automotive LED headlights, there is a certain thermal resistance between the light source module and the heat dissipation structure, resulting in a large temperature difference between the light source module and the heat dissipation structure, which cannot completely solve the problem of heat c...
