Recently, it has been learned from Chongqing Haihong Technology Co., Ltd. (hereinafter referred to as Haihong Technology) that its exclusive research and development “Lamp Radiator Low Temperature Direct Welding Technology†(LTS) can completely solve the heat problems that have plagued LED lighting for many years. Through this technology, the luminous efficacy and service life of LED lamps can be greatly improved, and the thermal conductivity will be improved by more than 10 times. The breakthrough of this technology suddenly attracted the eyes of the industry, but also let Haihong technology become famous, standing at the forefront of the LED industry.
With the increasing emphasis on environmental protection and the development of the LED industry, the application of large-scale promotion of high-power LEDs has become the trend of future development. However, although high-power LEDs have a lot of advantages for a long time, they also have high requirements for heat dissipation. When the LED junction temperature reaches a certain height, LEDs will quickly produce light decay, which will lead to a decrease in LED lifetime. Haihong Technology's "Light Bead Radiator Low Temperature Welding Technology" has brought a major breakthrough, opening the industry's forward "brow."
It is understood that this technology is to bond a certain thickness of copper cover layer on the surface of the aluminum radiator substrate through metallurgical bonding, to achieve a creative low-temperature direct welding of the lamp beads and the heat sink, completely solving the system's thermal bottleneck, and at the same time enhancing the light Bead heat source heat spreads laterally to the heat sink fins. However, the aluminum-copper cladding layer is not affected by the thermal stress and electrochemical corrosion of the dissimilar materials. In addition, the heat dissipation of the lamp beads is eliminated, and the thermal resistance of the interface material and the interface of the crimping method is eliminated. The heat transfer performance is not attenuated, thus completely solving the problem of aging and thermal conductivity degradation of the thermal conductive silica gel. The technology completely solves the problem of light failure of LED lamps, improves the light efficiency and service life, greatly reduces the cost, and brings the possibility for the promotion of large-area LED.
"Lamp Radiator Low-temperature Direct Welding Technology" (LTS) is a major innovation in the field of high-power LED lighting by the Haihong R&D team, making it one of the world's leading edge in this technology field. For a long time, this private high-tech enterprise, with its R&D, product manufacturing, and marketing as a whole, has been quietly engaged in low-carbon technology fields such as green manufacturing, green energy, and energy conservation and environmental protection, and has achieved a number of scientific researches that have reached the international advanced level. Achievements.
It is reported that Haihong Technology is relying on the "LTS" technology to integrate the efficient heat-dissipating modules for light sources, light distribution, power supply and lamps. It will be listed on the National Day before 2010 National Day, and will thoroughly clear the traditional lighting companies into the LED light source manufacturing field. Obstacles.
