A heat-dissipating method of a light emitting diode illuminator includes the following steps. First, the light emitting diode illuminator is provided and includes a light emitting diode, a fan apparatus, a temperature sensor and a controller. The controller is electrically connected with the fan and the temperature sensor. Second, a working temperature of the light emitting diode is sensed using the temperature sensor, and a signal of the working temperature is transmitted to the controller. Third, the working temperature sensed by the temperature sensor is compared with a predetermined working temperature in the controller, and the fan is adjusted by the controller to work at a suitable speed. |
