摘要
In case of opto-electronic devices, the power applied LED on the device leaves in a parallel heat and light transport, the interpretation of R-th is not obvious. The paper shows results of a combined optical and thermal measurement for the characterization thermal of power light emitting diodes (LEDs). A model explaining R-th changes at different current levels is proposed.
