| Abstract: | Forward-voltage method is used to measure light emitting diode （LED） junction temperature. By us？ing the data acquisition card, an automatic junction temperature measurement system of high power LED is devel？oped. The high power LED on market is measured and compared to build I-V characteristic and current junction temperature curves of high power LED. The measured results and characteristic curves are analyzed and discussed. |
