AI Technical Summary

Problems solved by technology

It is difficult to weld aluminum and aluminum alloys with aluminum, aluminum alloys, copper, and copper alloys, especially after anodizing the surfaces of the above-mentioned aluminum and aluminum alloy materials. The heat dissipation performance is reduced, which leads to the rapid decay of the pearl light of the LED lamp and reduces the service life of the LED car lamp; the structure of the integral molding of the lamp holder and light pole is high in cost, low in efficiency and poor in thermal conductivity

Abstract

The invention discloses a high-heat-dissipation type LED car lamp structure and a welding preparation method thereof, and relates to the technical field of LED illumination, the high-heat-dissipation type LED car lamp structure comprises a lamp holder, a lamp pole, a lamp panel assembly and a fan assembly, the lamp pole is provided with a tin storage groove for being filled with solder paste, the lamp pole is welded to the lamp holder, the lamp pole is provided with a first solder paste layer, the first solder paste layer is located at the welding position of the lamp holder and the lamp pole, the second solder paste layers are arranged on the two side faces of the lamp panel assembly respectively, the fan assembly is installed in the lamp holder, the lamp pole wraps the periphery of the lamp panel assembly, and one end of the lamp panel assembly is arranged on the fan assembly. After the technical scheme is adopted, silicone grease coating connection is replaced by solder paste welding, and the heat conductivity coefficient of the solder paste is more than 7 times higher than that of heat-conducting silicone grease, so that the LED lamp tube is high in heat conduction efficiency and excellent in heat dissipation performance, and the lamp tube is slow in light attenuation and long in service life.

Description

technical field [0001] The invention relates to the technical field of LED lighting, in particular to a structure of a high heat dissipation LED car lamp and a welding preparation method thereof. Background technique [0002] LED car lights refer to car lights that use LEDs (light-emitting diodes) as light sources. Because LED has the characteristics of high brightness, rich color variety, low power consumption, and long life, LED is widely used in the automotive field. [0003] The existing aluminum parts of LED lights such as light poles, heat pipes, light boards, and lamp holders are connected by riveting or chemical immersion to increase the surface energy of the aluminum parts and then welded; Welding, and then use the method of riveting to smear the heat-conducting silicone grease on the lamp holder and connect it with the lamp pole, lamp board, and heat pipe assembly. The low coefficient (the thermal conductivity of thermal conductive silicone grease is less than 7....
