摘要：
A light emitting diode (LED) structure, a manufacturing method thereof and a LED module are provided. The LED structure has temperature sensing function. The LED structure comprises a composite substrate and an LED. The composite substrate comprises a diode structure whose P-type semiconductor region or N-type semiconductor region has a predetermined doping concentration. The diode structure is a temperature sensor, and the sensitivity of the temperature sensor is based on the predetermined doping concentration. The LED is disposed on the composite substrate. The diode structure is used for sensing the heat emitted from the LED.
