Analysis and Research of the High Power LED Temperature Characteristics

Abstract:

This paper is mainly about the high power LED temperature characteristics. With the integrating sphere, we conduct an experiment to observe and analysis the relationships of temperature and color coordinates, peak wavelength, color temperature, forward voltage, peak bandwidth, color purity, electric power. Finally we get that the temperature is the main factor to affect the color performance of white LED photoelectric, with the white LED apparent temperature rise, forward voltage, the color coordinates and color purity tends to go down. On the contrary with increasing junction temperature, the half-value wavelength and color temperature are increased accordingly.
