High-power LED lamp cooling solution
As the small components of electronic devices continue to add powerful functions, temperature control has become one of the important factors in the design. How can the heat generated by high power be effectively reduced when the architecture is tight and the operating space is getting smaller and smaller?
High thermal conductivity soft silicone thermal insulation mats are widely used in LED lighting, automotive electronics, displays, computers, and power supplies.
High thermal conductivity soft silicone thermal insulation mat is widely used in LED floodlights. High thermal conductivity soft silicone thermal insulation mat material is soft, used for the surface of the lamp, can perfectly cover the rough surface of the lamp, reduce the thermal resistance of the air, and the thermal conductivity of the high thermal conductivity soft silicone thermal insulation pad, to the greatest extent Heat dissipation requirements, increased accessory power and extended use time; continuous testing at high temperature 160 ° C for 150 hours, stable performance. High thermal conductivity soft silicone thermal insulation pad suitable for the LED flood light, LED garden light, LED fuse light, LED pixel light, LED underwater light, LED waterproof flood light, LED light cup series.
The high thermal conductivity soft silicone thermal insulation insulating pad is one of the heat transfer materials, which can be cut according to the size and shape of the heating accessory, has good thermal conductivity and insulation properties, and is filled in the gap between the heating component and the heat sink. It is an ideal product to replace thermal grease.
At present, many manufacturers still use thermal grease as the thermally conductive material of LED lamps. Although the thermal conductivity of thermal grease is very good, the insulation is relatively poor, and the most serious problem is that it is easy to age under certain working conditions. More troublesome, it is easy to dirty the surrounding accessories, resulting in a short circuit. It is easy to age the lamp, which affects the use time of high-power LED lamps. The use time of high-power LEDs is generally 50,000 hours. However, if thermal grease is used as the heat-conducting material, the thermal grease will slowly change with the use of lamps. Dry, the thermal conductivity is reduced, which will affect the normal heat dissipation of the lamp, and the life of the lamp will also be affected.
