Patent ID: 8482207

Claim:
A temperature controlling system for a LED module, including: at least one LED unit having a plurality of LED chips; at least one fan provided on one side corresponding to the LED unit for compulsively dissipating the heat generated by the LED unit; at least one temperature sensor positioned adjacent to the fan for detecting an ambient temperature of external environment and temperature values around the at least one fan to thereby generate a temperature detection signal; and a control device, comprising: an interface circuit electrically connected to the fan and the temperature sensor; a power supply electrically connected to the fan and the LED unity; and a microprocessor electrically connected to the interface circuit for generating a driving signal to control a rotating speed of the fan based on the temperature detection signal; wherein the microprocessor recognizes the ambient temperature of said external environment and the temperature values around the respective fans based on the temperature detection signal and compares them with a preset temperature, and wherein the microprocessor generates a warning signal to a connected terminal device if the ambient temperature of said external environment and one of the temperature values around the respective fans exceeds a preset temperature.
