High-power LED car lamp

Abstract

The invention relates to the technical field of illumination, and in particular relates to a high-power LED car lamp. The high-power LED car lamp comprises an LED light source assembly, a heat conduction pipe used for mounting the LED light source assembly, a heat dissipator used for dissipating heat, a cooling fan used for accelerating heat dissipation, and a clamping base assembly used for mounting and positioning the LED car lamp, wherein the heat dissipator comprises a heat dissipating main body and heat dissipating structures, each heat dissipating structure comprises a main reinforcing bar uniformly distributed around the axis of the heat dissipator and a heat dissipating fin vertical to the main reinforcing bar, first cooling air channels with equal intervals are formed between theadjacent dissipating fins, the first cooling air channels of the adjacent dissipating structures are vertical to each other, the heat conduction pipe is provided with a pipe body and a heat conductionplate, the heat conduction plate is arranged in the pipe and forms a second heat dissipating air channel with the pipe body, a heat dissipating base is further arranged at one end of the pipe body, afirst air opening communicating with the first heat dissipating air channel is arranged at the position, connecting with the heat dissipating base, on the pipe body, and a second air opening communicating with the first air opening and the second heat dissipating air channel is arranged at the connecting part of the heat dissipating base. The structure is good in heat dissipation, and thus the service life of the LED car lamp is prolonged.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to a high-power LED vehicle lamp. Background technique [0002] LED car lights refer to car lights that use LEDs 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] As we all know, because car lights are generally multi-faceted light-emitting lights, the heat source of LED car lights is concentrated and heat dissipation is difficult. In addition, the LED light source itself is small in size and the heat generated is relatively concentrated. That is, the LED light source can provide high brightness output while also A large amount of heat is generated. However, in a high-temperature working environment, the LED light source will have problems such as color shift and brightness reduction. If the heat dissipation is not timely, it will seriously affect ...

AI Technical Summary

Problems solved by technology

The heat dissipation air channel formed by its heat dissipation fins has a large wind resistance, and no rapid convection is formed, and the heat dissipation effect is not good, which is not conducive to heat dissipation
