外文摘要：The photometric, electrical, thermal and life features of LEDs are highly dependent on each other. All these factors should be considered together in order to optimize the operating point of LEDs. A thermal-life theory about LEDs is developed. This theory shows the inner inks among photometric thermal and 1ife features of a LED. A life prediction model of LEDs and the relationship between output luminous flux and lifetime was found out by this theory. The life of LEDs can be predicted and find the proper operating point, at which the LED will generate the maximum amount of luminous flux in its total life cycle. ?
