Abstract

The invention discloses a liquid-cooled LED headlamp for a means of transportation. The liquid-cooled LED headlamp comprises a columnar closed cavity heat dissipation lamp body. The heat dissipation lamp body is filled with cooling liquid. A plurality of LED lamp beads are evenly arranged along the columnar surface of the heat dissipation lamp body. A hot water pipe connector and a cold water pipe connector are formed in one end of the heat dissipation lamp body and are connected with a water-cooled heat sink through a hot water pipe and a cold water pipe respectively. By the adoption of the liquid circulation heat dissipation technology, the heat dissipation efficiency of the lamp body is improved, and the purpose of dissipating heat of the LED headlamp in an airtight working environment is successfully achieved. The reliability and the service life of the LED headlamp are guaranteed, the service life of the LED headlamp is 10-30 times longer than that of a traditional lamp, and it is made possible that the headlamp of the means of transportation does not need to be replaced at all. Based on the design of an integrated lamp cap, the LED headlamp can be easily and conveniently realized just by replacing an original light source of an original car assembly, and the LED headlamp meets various regulatory requirements of various countries on headlamps.

Description

technical field [0001] The invention relates to the technical field of LED lighting, in particular to a liquid-cooled LED headlamp for vehicles. Background technique [0002] Today, LED technology has been widely used in various vehicles. For example, most motor headlights have also adopted LED technology. Although under the same brightness conditions, LEDs save more power than traditional lamp beads, but because LED headlights are in a closed working environment, how to dissipate heat is an urgent problem to be solved. At present, the heat dissipation method of the existing LED headlights is through conduction heat dissipation. This method has relatively low heat dissipation efficiency, resulting in shortened service life of LED headlights, increased frequency of replacement headlights, and greatly increased maintenance costs. Contents of the invention [0003] In view of the above existing problems, the present invention provides a liquid-cooled LED headlamp for vehicle...
