Abstract
2D thermoreflectance images of light-emitting diodes (LEDs) show lateral temperature variation with contact design. Thermoreflectance imaging of LEDs is quantitatively compared with standard bulk temperature measurements. Encapsulation improves heat dissipation and reduces optical reabsorption heating.
