摘要
LED是一种电致发光器件,电流与器件出光有直接的关系,该文讨论了在不同电流下,功率型白光LED发光的色温、光通量、色坐标等光学参数的变化,并分别得到相应的结论。
LED is a kind of electroluminescent device. The character of output light has immediately relation with the applied current. Some conclusions has been draw basing on discussing the optical parameters for power White - LED, such as luminous flux, correlation color temperature, chromaticity and so on, when the device was applied different current.
