Description
technical field [0001] The invention relates to an LED lamp, in particular to a rapid heat dissipation LED lamp. Background technique [0002] The heat dissipation problem of LED is the bottleneck of the development of semiconductor technology at present. In the prior art, the photoelectric conversion efficiency of incandescent lamps is only 3%, that of fluorescent lamps is about 15%, that of LEDs is 10% to 40%, and 60% to 90% is converted into heat. The junction temperature has a great impact on the life of the LED. When the junction temperature is 60-80 degrees, the thermal conversion efficiency of the LED is about 70%-80%. When the temperature of general electronic parts rises by 10°C, the life span becomes about half. 2°C, the reliability will drop by 10%. Therefore, the heat dissipation problem of LED is of great significance to improve its photoelectric conversion efficiency, improve its service life and reliability. [0003] With the continuous increase of the cap...
