Abstract
A light emitting diode (LED) includes a substrate, a temperature detecting pattern, and a semiconductor structure. The temperature detecting pattern is formed on the substrate. Then the semiconductor structure is formed on the temperature detecting pattern and the substrate. The semiconductor structure includes an n-type semiconductor layer, a p-type semiconductor layer, and an active layer. Per above-mentioned structural design, the temperature detecting pattern directly integrated into the LED can measure the actual temperature of PN junction with high precision.
