Problems solved by technology

[0002] The heat dissipation of LED lights is now more and more valued by people. This is because the light decay or life of LED lights is directly related to its junction temperature. If the heat dissipation is not good, the junction temperature will be high and the life will be short. According to the Arrhenius law Every time the temperature drops by 10°C, the life will be extended by 2 times. From the relationship between light decay and junction temperature released by Cree, it can be seen that if the junction temperature can be controlled at 65°C, then the life of light decay to 70% can be as high as 100,000 hours ; but the heat dissipation of the existing actual LED lamps is far from reaching the required temperature, so that the life of the LED lamps has become a major problem affecting its performance. Moreover, the junction temperature not only affects the long-term life, but also directly affects Short-term luminous efficiency
