Adaptive light emitting diode (LED) illumination device and control method thereof

Abstract

The invention discloses an adaptive light emitting diode (LED) illumination device and a control method thereof. The device comprises a microprocessor, a sensor part, a power module and an adjustable constant current drive module, wherein the microprocessor receives sensing signals in real time, and changes a drive current to change the luminance of an LED by controlling the output of the adjustable constant current drive module according to the sensing signals; the sensor part is connected with the microprocessor, and is used for detecting the data information of an illumination environment and transmitting the data information to the microprocessor; the power module and the adjustable constant current drive module are connected with the microprocessor; the power module is used for supplying power to the whole device; and the adjustable constant current drive module is controlled by the microprocessor, and is used for outputting a constant current to drive an LED lamp to emit light. Due to a front light sensing function, a motion sensing function, a temperature control function, a time control function or/and an luminance sensing function, the device and the control method thereof save electric energy, reduce the heating of the LED, prolong the service life of the LED, meet requirements on the adaptive change of color temperature of a fluorescent lamp along with external change, and provide a more comfortable illumination environment.
