| Heat dissipation has always been a problem for LED lamps, and at the same time, the heat conduction process between the heating element and the heat sink is even more critical. The thermal conductive material used in the traditional heat dissipation mode is thermally conductive silicone grease. Thermally conductive silicone grease is more economical in terms of cost and has a good thermal conductivity. However, when large areas are required to be applied, the components cannot be evenly applied and may be contaminated to a certain extent. The soft silicone thermal conductive sheet is used in the contact between the heat dissipation copper plate and the heat sink or metal bracket lamp and metal shell. It can be laid on a large area and is easy to operate. The thinnest is 0.5mm, and the thickness is optional, 1.0mm, 1.5mm... .5mm thickness, the thickest can reach more than 10mm, high compression ratio, can effectively transfer heat to the heat sink. Our company has been committed to the research and development and production of thermal interface materials for more than ten years. Now in order to meet the requirements of the domestic LED lighting industry, our company combines the cooperation experience of the relevant LED industry to understand the heat dissipation requirements and structural characteristics of LED lamps, and conduct targeted research and development And produce LED thermal silica gel and put it on the market. The flexible thermal conductive silicone sheet has the technical characteristics of high compression ratio, self-adhesive surface, which makes the installation conditions easier, and has superior weather resistance and high pressure resistance. After being used by relevant manufacturers in the industry, the heat transfer effect is obvious, reducing the internal temperature of the device for a long time, greatly increasing the service life of the LED lamp, reducing the loss of light and heat energy, reducing the light attenuation to a certain range, and improving the performance of the LED lamp ( Such as life, lumen, ambient temperature, etc.). At present, LED thermal conductive silicone sheets are widely used in high-power LED lamps, with power ranging from 18W to 200W; such as: LED street lamps, spotlights, floodlights, tunnel lights, underground lights, wall washers, and dyeing lights and many more Flame retardant and fireproof performance meets U.L94V-0 requirements and meets EU SGS environmental protection certification. The working temperature is generally -50℃～220℃. (This article is transferred from thermal silica gel sheet) | ||
