Abstract

The invention discloses a heat dissipation coating for an LED lamp. The heat dissipation coating for the LED lamp is characterized by comprising the following components in parts by weight: 100 parts of a film forming material, 50-80 parts of heat-conduction silicone grease, 30-50 parts of heat-conduction packing, 300-500 parts of a volatile organic solvent, 10-30 parts of a plasticizer, 2-6 parts of a weather-proof agent, 2-5 parts of a coloring agent and 3-8 parts of a surfactant. The heat dissipation coating for the LED lamp is good in stability, long in service life, high in heat dissipation property and high in visible light, near-infrared light and thermal infrared light reflectivity, and cannot fade easily.

Description

technical field [0001] The invention relates to a heat-dissipating coating for 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. [0004] The heat cap...
