| Abstract: | Physical mechanism of the forward voltage changes with the operator temperature is analyzed in this paper, and a measurement system is built to research these changes. The linear fitted method is used to analyze the experiment data, and the coefficient of the forward voltage changes with temperature is gotten for many types light emitting diodes, it is very important parameter for the thermal control and device structure design of ultra high brightness, power LED devices and assemble. |
| Keywords: | Power LED Forward voltage Coefficients of forward voltage Vs temperature |
