Confocal Thermoreflectance for Spatially Resolved Surface Thermography of Transparent LEDs

Not Accessible

Your library or personal account may give you access

Abstract

We report on the use of confocal thermoreflectance for accurate surface temperature measurement of transparent LEDs. Confocal thermoreflectance effectively suppresses light from beneath the LED surface, compared to widefield measurements, for a red GaP LED.
