Light emitting diode (LED) light source heat dissipation intelligent control device

The utility model discloses a light emitting diode (LED) light source heat dissipation intelligent control device. The LED light source heat dissipation intelligent control device comprises a micro-programmed control unit (MCU), a temperature sensor and a heat dissipation fan, wherein the temperature sensor and the heat dissipation fan are respectively connected with the MCU, the temperature sensor is connected with the MCU through a 1-wire bus, the heat dissipation fan is connected with the MCU through a four-wire fan port, the four wires of the fan port respectively refer to a power supply wire, a ground wire, a PWM, and an FG, the heat dissipation fan is high in speed, and the model of the temperature sensor is DS18B20. According to the LED light source heat dissipation intelligent control device, the MCU is connected with the temperature sensor to detect temperature, and the rotation speed of the heat dissipation fan can be real-timely adjusted according to actual temperature, and therefore the purpose of energy conservation can be achieved on the condition that heat dissipation requirements are met. Moreover, the MCU can detect the actual rotation speed of the fan to determine the operation state of the fan.
