摘要（英）：

The invention discloses a device and a method for representing a GaN-based LED junction temperature by a centroid wavelength and a spectral width. The device comprises a thermal resistant structure analyzer, a thermostat and an integrating sphere, wherein an LED lamp seat, a spectrum analyzer and a computer are arranged on the thermostat, the signal transmission end of the spectrum analyzer is connected with the computer, a spectrum analyzer probe is arranged in the integrating sphere and reaches to the inner wall of the integrating sphere by penetrating through the integrating sphere, an LED light source mounted on the LED lamp seat is connected to the thermal resistant structure analyzer and penetrates into the integrating sphere, and a driving power source is connected to the computer. The device and the method for representing the GaN-based LED junction temperature by the centroid wavelength and the spectral width have the advantages that the method and the device for measurement are accurate, reliable, convenient and simple, and the GaN-based LED junction temperature can be measured by the simple and efficient device at low use cost and without contacting with an LED.
