The invention discloses an automobile LED headlamp with a heat dissipation structure. The automobile LED headlamp comprises an LED installing plate and a plurality of LED lamp beads, wherein a radiator is arranged on the rear side of the LED installing plate, an air inlet pipe is connected with the lower end of the radiator, an air outlet pipe is connected with the upper end of the radiator, the radiator comprises a heat dissipation bottom plate, a plurality of transverse heat dissipation pipes are evenly arranged on the heat dissipation bottom plate, a plurality of longitudinal heat dissipation pipes are evenly arranged on the outer sides of the transverse heat dissipation pipes, the two ends of the transverse heat dissipation pipes are connected with air distribution connectors respectively, and the two ends of the longitudinal heat dissipation pipes are respectively connected with air distribution connectors. A heat dissipation cover plate is arranged on the outer sides of the longitudinal heat dissipation pipes, an air inlet hole is formed in the lower end of the heat dissipation cover plate, an air outlet hole is formed in the upper end of the heat dissipation cover plate, the air inlet hole is communicated with the air inlet pipe through a connecting pipe, and the air outlet hole is communicated with the air outlet pipe through a connecting pipe. In this way, the radiator in the automobile LED headlamp can timely and effectively absorb heat emitted by the automobile LED headlamp and timely discharge the heat, the heat dissipation effect is good, and therefore service life of the automobile LED headlamp is prolonged.
Description
technical field [0001] The invention relates to an automobile LED headlamp, in particular to an automobile LED headlamp with a heat dissipation structure. Background technique [0002] In recent years, with the emergence of high-brightness LED technology, LEDs have begun to be used in automotive exterior lighting. LEDs have the advantages of long service life, high color purity, fast response, small size, and easy design. At present, LED car lights have It has become the new darling of the automotive lighting trend and is widely used in signal lamps such as turn signals and brake lights, and has gradually begun to be applied to automotive headlights. Car headlights are the lamps with the largest power consumption among all car lamps, so LED car headlights need high-power LEDs, but the heat dissipation problem of LEDs is the technical bottleneck for the application of high-power LEDs in lighting systems. The heat generated is concentrated in the silicon chip inside the LED l...
