The development of LEDs towards high power is an inevitable trend. The problem of heat conduction and heat dissipation that has been extended here has become an urgent problem to be solved in the industry. Dr. Ye Shengwei, head of the R&D department of Guanpin Chemical, said that the thermal resistance of LED products is not only to use thermal adhesive, but also to improve the interface thermal resistance of various media bonded by thermal conductive adhesives, such as epitaxy and substrate, substrate and heat dissipation. The module is coated with an insulating thermal conductive adhesive at the bottom of the epitaxial layer when the epitaxial adhesion is applied, and the insulating thermal conductive adhesive is integrally coated between the circuit board and the thermal conductive aluminum substrate, and then bonded to the heat dissipation module, thereby completely reducing the overall thermal resistance, so that The efficiency of LEDs is more effective. Crown soft ceramic thermal adhesive itself is a heat sink, which can greatly simplify the structure of the heat dissipation module, reduce the system temperature, and effectively eliminate thermal energy. The heat-resistant temperature is as high as 400 degrees Celsius, and there is no doubt about the explosion-proof plate and the curved plate.
Han De, general manager of Guanpin Chemical, said that since the introduction of the heat-dissipating LED white backlight ink in 2007, Guanpin has mass-produced soft ceramic insulating thermal adhesive, and reduced the cost for the overall thermal solution. Recently, LED outdoor lighting manufacturers should be required to provide anti-acid and anti-acid coatings for outdoor use of street lamps, wall washers, lanterns, marine navigation lights, etc., and develop a new generation of LED outdoor lighting heat-dissipating paint. This type of heat-dissipating paint can be applied in the form of paint, can withstand the acid value of PH 3 ~ 11 and a considerable degree of assembly impact, the sprayable area per kilogram is about 40 ~ 50 square meters, the material cost is lower than NT$ 90 / square meter It can effectively solve the pain of poor heat dissipation of existing lamps after anodizing or baking.
At present, a number of operators have actively introduced production, and it is estimated that at the end of 2009, household LED lamps that are closer to the target price of consumers will be listed.
As we all know that the parents all over the world pay more attention on children education, so more and more businessman do education laptop deals, therefore education laptop is becoming one of the most important fields no matter on customizing laptop or brand one.
