China's research and development of the world's leading LED lighting cooling technology, thermal conductivity will be increased by more than 10 times

Cooling technology, the problem plagued LED lighting for large-scale applications, has finally been a crucial Chinese enterprise!

Recently, from Chongqing Haihong technology limited liability company (hereinafter referred to as Haihong Technology) learned that the exclusive development of the lamp radiator low temperature direct welding technology "(LTS) can completely solve the problem of heat dissipation of LED lighting in the area for many years. Through this technology, the light efficiency and the service life of the LED lamp can be greatly improved, and the thermal conductivity will be increased by more than 10 times. This technological breakthrough once attracted industry vision, also let the station to the forefront of science and technology Haihong fame, LED industry.

Development along with the growing emphasis on environmental protection and LED industry, a large area of application of large power LED has become the trend of future development. However, for a long time although the high-power LED has many advantages, but the cooling technology requirements are very high, the LED junction temperature reaches a certain height LED will soon lead to the decay of LED decreased life expectancy. The lamp radiator low temperature welding technology Haihong science and technology "has brought a major breakthrough, opened the industry forward" brow".

It is understood that the technology is a combination of a certain thickness by metallurgical bonding in the aluminum radiator substrate is bonded to the surface of the copper layer, achieved lamp and radiator temperature straight welding, completely solve the bottleneck of cooling system, and enhance the lamp heat to the radiator fin heat source lateral diffusion. The aluminum covered layer molecules from dissimilar materials, the effect of thermal stress and electrochemical corrosion. With the lamp radiating straight welding, elimination of thermal interface materials and crimping interface. The heat transfer performance is not reduced, so that the problem of the aging of the conductive silicone rubber and the decrease of the thermal conductivity is thoroughly solved. This technology completely solves the problem of attenuation of LED lamps, improves the light efficiency and service life, greatly reduce the cost, bring the possibility for the promotion of LED in large area.

"Lamp radiator low temperature direct welding technology (LTS) is a major innovation in Haihong R & D team in the high power LED lighting field, which in the technical field of one at the forefront of the world level. But for a long time, the technology research and development, production, marketing as one of the private high-tech enterprises have been in the technical field of green manufacturing, green energy and low-carbon energy-saving and environmental protection work quietly, and made a number of international advanced level of scientific research.

It is reported that, Haihong technology with "LTS" technology, efficient cooling module integrated light source, light distribution, power supply, lighting will be listed in 2010 Grand National Day, will completely clear the traditional lighting light source manufacturing enterprises to enter the LED field obstacle.

Lamp - radiator direct welding technology through metallurgical bonding mode in a certain thickness of aluminum radiator substrate is bonded to the surface of the copper layer. The lamp - radiator straight welding, eliminate the crimping interface material and interface thermal resistance. Copper coating enhanced lamp point heat source heat to the radiator fin transverse diffusion. Aluminum covered layer molecules from dissimilar materials, the effect of thermal stress and electrochemical corrosion. Heat transfer performance does not decay. The problem of reducing the thermal conductivity of conductive silicone rubber was solved thoroughly.

Application effect

Thermal conductivity: up to 50 (W/m.K), increased by more than 15 times.
