Abstract

The invention relates to the technical field of LED lamp assemblies, and in particular relates to an LED heat dissipation lamp holder and a preparation method thereof. The heat conduction effect of anLED lamp radiator can be improved by means of internal addition, so that heat generated by a LED lamp during operation can be timely dissipated, and the problems of excessive light decay and short life due to the accumulation of the heat of the LED lamp can be avoided. The LED heat dissipation lamp holder produced by the method not only has excellent thermal conductivity, but also has anti-agingperformance, and avoids the problems of light decay and shortened life due to excessive temperature rise of the LED lamp.

Description

technical field [0001] The invention relates to the technical field of polymer materials and LED lamp components, in particular to an LED heat dissipation lamp holder and a preparation method thereof. Background technique [0002] LED light sources have the advantages of small size, low power consumption, long service life, high brightness, and environmental protection, and are known as the darling of green lighting in the 21st century. Since the light decay and lifespan of LED lamps are directly related to their temperature, people pay more and more attention to the heat dissipation of LED lamps. [0003] As an important part of the LED lamp, the heat sink can dissipate the heat generated by the LED lamp in a timely manner. At present, the most common LED lamp heat sink is extruded or die-cast from aluminum alloy, but due to its large specific , High processing cost and low efficiency limit its application in radiators for high-power LED lamps. Compared with aluminum allo...
