Problems solved by technology

Oxidation of the surface of the heat pipe will lead to a significant increase in the thermal resistance between it and the radiator (radiation component), which in turn will cause a rapid decline in the heat dissipation performance of the LED car light, seriously affecting the service life and stability of the LED car light
However, none of the above-mentioned patent documents is aware of the rapid decline in heat dissipation performance caused by the oxidation of the outer surface of the heat pipe.

Abstract

The invention provides an LED (Light-emitting Diode) automobile light and a preparation method thereof. The automobile light comprises a metal heat pipe with a light source installation section and a heat conduction section, LED light sources arranged on the light source installation section, and a heat radiator comprising a metal radiator and a thermal conductive plastic isolator, wherein the metal radiator and the heat conduction section form thermal connection; and the thermal conductive plastic isolator covers the heat conduction section so as to separate the heat conduction section from outside air. The LED automobile light provided by the invention has the advantages of excellent heat radiation performance and long service life.

Description

technical field [0001] The invention relates to an LED vehicle light and a preparation method thereof; wherein, the LED vehicle light is used as an illumination light source of a vehicle-mounted lighting fixture. Background technique [0002] Compared with traditional lighting sources, LED light sources have the advantages of long life, low power consumption, small size, fast response, flexible design, and flexible control. With the continuous advancement of LED technology and people's higher requirements for energy-saving and environmentally friendly products, the number of vehicle-mounted lamps using LED lamps as lighting sources continues to increase, and its large-scale application in automotive lighting has become an inevitable trend. As we all know, since the service life and luminous efficiency of LED light sources are closely related to their operating temperature, the heat dissipation performance has become one of the key factors restricting the performance of LED l...
