| Abstract: | With many advantages, such as small volume, low voltage, long life, energy conservation, LED is dominant in many light sources. However, heat dissipation problem is the bottleneck for the LED development. To begin with, total thermal resistance of high - power LEDs is analyzed and some factors affecting the heat dissipation of high - power LEDs are confirmed. Moreover, latest advances for heat dissipation are introduced. |
