| dcterms.abstract | The paper examines the high power Light Emitted diode (LED) and the hear distribution of the heat sink. Beside we also study the relationship between temperature and the current on the LEDs luminous efficiency. The temperature rise to over the limit level that the luminous efficiency will decrease rapidly. The current increase will cause the nonequilibrium electron diffuse out of the potential wall and will increase the temperature, so as to decrease luminous efficiency and the LEDs life [1]. Enhancing the heat manage of LEDs that can improve the luminous efficiency. Thermal design examines by using the thermal analysis. Finally we propose the electrical circuit to drive the LEDs in constant current power to maintain the temperature more constant of LEDs. | - |
