Special materials for LED lamp heat dissipation
Heat dissipation is a key problem to be solved by LED lights, and before that, a heat conduction process 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, but it has a big problem when it needs to be applied on a large area and cannot be applied evenly. The contact between the heat dissipation copper plate and the heat sink or metal bracket lamp and metal shell. Now many LED lamp manufacturers use the soft silicone thermal pad provided by our company, which can be used for large-area bedding and easy to operate. The thinnest is 0.5mm, and the thickness can be Choose from 1.0mm, 1.5mm...5mm thickness, the thickest can reach 16mm, and the compression modulus is 20%-25%, which can effectively transfer heat to the heat sink.

In addition, the use of thermally conductive silicone sheets is also a good choice. Our company is a professional manufacturer of independent research and development, production and sales of thermal interface materials. Now in order to meet the requirements of the domestic LED lighting industry, the company combines the cooperation experience of the relevant LED industry to understand the heat dissipation requirements and structural characteristics of the LED lamps, and conduct targeted research and development And produce LED thermal silica gel (model SP150) and put it on the market.
SP150 thermally conductive silica gel has good thermal conductivity (thermal conductivity of 1.99w/mk), SP160 thermal conductivity of 2.75w/mk. It is soft and high compression ratio, and the surface has its own adhesiveness, which makes installation conditions easier, weather resistance and high pressure resistance. Technical characteristics. 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, lumens, ambient temperature, etc.).
At present, LED thermal silica gel is widely used in high-power LED lamps, with power ranging from 18W to 200W; such as: LED street lights, spotlights, floodlights, tunnel lights, underground lights, wall wash lights, dyeing lights, etc. Wait. Flame retardant and fireproof performance meets U.L 94V-0 requirements and meets EU SGS environmental protection certification.
The working temperature is generally -50℃～220℃, welcome to inquire, we will send you the information and samples.
