Abstract

The invention discloses a high-performance LED lamp heat-radiating coating. The coating is characterized by comprising, by weight, 100 parts of inorganic colloidal particles, 20-40 parts of a film forming material, 50-80 parts of heat-conducting silicon grease, 30-50 parts of a heat-conducting filler, 300-500 parts of a volatile organic solvent, 10-30 parts of a plasticizer, 2-6 parts of a weather resistant agent, 2-5 parts of a colorant and 3-8 parts of a surfactant. The high-performance LED lamp heat-radiating coating is high in stability, less prone to fading, long in service life, high in heat-radiating performance and high in visible light, near infrared and thermal infrared reflectivity.

Description

technical field [0001] The invention relates to a heat-dissipating coating for high-performance LED lamps, which belongs to the technical field of polymer materials. Background technique [0002] As LED technology has received widespread attention as a new generation of lighting technology in recent years, the power of LED has increased, and the problem of heat dissipation has also been paid more and more attention. The light decay or lifespan of an LED is directly related to its junction temperature. If the heat dissipation is not good, the junction temperature will be high and the lifespan will be short. [0003] The reason why the LED heats up is that not all of the added electrical energy is converted into light energy, but part of it is converted into heat energy. The light efficiency of LED is currently only 100lm / W, and its electro-optical conversion efficiency is only about 20~30%. That is to say, about 70% of the electrical energy is turned into heat energy. [0...
