First it included the LED's structure, the working theory, the LED P-N close temperature and it's theory. The analysis is given to the relation between the P-N and spectra charactor.Then it focus on the analysis of large power LED 's P-N close related to the spectra, according to the practical calculating, it select the data and do analysis ,discuss and finnaly support the theory is correct
备注：温结我用了P-N temperature close 翻译，不是很准确。
This paper introduces the structure, principle of leds and LED the temperature and the reasons, and the temperature is theoretically the relationship between spectra characteristics are analyzed. Then from the Angle of the experiment on high-power blue leds with spectral characteristics of temperature, carries on the actual measurement, and the measurement data was analyzed, the experimental results show that the discussion with the theory.
