Crown chemistry: LED heat to be resolved, should focus on the overall thermal resistance

It is reported that in recent years, guanpin chemical resistance to the overall concept, developed a new type of LED thermal insulation adhesive. The product with the radiation type LED backlight white ink, not only to help the industry to reduce the cost of at least 50~70%, but because the thermal resistance of less than 0.6 cm 2.K/W, can effectively eliminate the heat, let LED light conversion more effectively.

LED towards high power development is an inevitable trend, resulting in a stretched out heat and cooling problem has become urgent problems at present. Guanpin Chemical Research Director Dr. Ye Shengwei said, LED is not just a low thermal resistance to the heat conduction glue, interface thermal resistance of various media but also improve the adhesive bonding, such as epitaxial substrate, and the substrate and the heat dissipation module, if the epitaxial adhesion on the insulating heat conducting adhesive coating in epitaxial bottom the circuit board, and thermal conductivity of aluminum substrate is overall coating thermal insulation adhesive, bonding and radiating module, can drastically reduce the overall thermal resistance, make the efficiency of LED is more effective to play. Crown soft ceramic thermal conductivity itself is a heat sink, can greatly simplify the structure of the cooling module, reduce the system temperature, effectively eliminate the heat. Heat resistant temperature up to 400 degrees Celsius, no explosive plate, bending plate doubts.

Guanpin Chemical General Manager Han guanpin said that since the 2007 launch of a white backlight radiating LED ink, then the production of soft ceramic thermal insulation adhesive, with the overall cooling solution for manufacturers to reduce costs. Recently, LED outdoor lighting manufacturers should all the requirements, and can be used in navigation lamps and so on to provide anti acid protection and radiating coating for outdoor use lights, wall lights, lanterns, King ship, developed a new generation of LED outdoor lamp radiating paint. This type of paint can form coating spray cooling, can be assembled under PH 3 ~ 11 pH value and considerable impact per kilogram spraying area is about 40 ~ 50 square meters, the material cost is lower than NT$90/ square meters, can effectively solve the existing lighting caused by powder of poor heat pain in anodic treatment or after baking.

Currently has a number of industry actively into production, estimated at the end of 2009 will have home LED lamps closer to the consumer price target market.
