英语翻译本文首先介绍了LED的结构、发光原理和LED的结温及其产生的原因,然后重点从实验的角度探讨大功率蓝光LED的结温

This article firstly introduced the structure,principle for lighting and the cause of this temperature's occuring of the LED,then focus from the experiment in the context of the blue light LED with great power and spectral characteristics,the law is the voltage and thermal resistance of three blue light led power in a practical measure,to the survey data on the analysis and discussion,the calculation of the three types of blue light led thermal resistance,and the results showed that the temperature rise and the current drive to increase,will lead to the LED junction temperature rise; junction temperature will rise to the main led wavelength of blue light to red,the Optical Wavelength corresponding to the different agenda
