Abstract
There are many available junction temperature measurement methods of LEDs. These methods depend on some characteristics of LEDs related to junction temperature. In this study, it has been taken advantage of the relative variation of radiant power with junction temperature characteristic of LED to measure junction temperature. The error ratio of the calculated junction temperature decreases in pulsed high currents..
Keywords
