LED CONTROLLING DEVICE

摘要

A light emitting diode (LED) controlling device may include: a driving circuit unit converting input power into an output voltage and providing the output voltage to an LED module; a detecting circuit unit positioned between the driving circuit unit and the LED module and detecting the output voltage and an output current of the LED module; and a controlling circuit unit converting an external signal into a reference signal and comparing the reference signal with at least one of the output voltage and the output current to control an output of the LED module. The external signal may be one of a first signal provided by a sensor module, a second signal provided by a communications module, and a third signal provided by an output control module.
