Title:
MULTI-GEAR CURRENT REGULATION LED MICROWAVE-SENSING DIMMER
Document Type and Number:
WIPO Patent Application WO/2015/106484
Kind Code:
A1
Abstract:
Provided is a multi-gear current regulation LED microwave-sensing dimmer, comprising a drive circuit, wherein the drive circuit is provided with an AC input for connecting to a commercial power supply and a drive output for connecting to an LED light-emitting circuit, and further comprising a control circuit, wherein the control circuit comprises an HF microwave detection module and an MCU control module, the HF microwave detection module is connected to an input of the MCU control module, and a PWM control signal output of the MCU control module is connected to the drive circuit. The multi-gear current regulation LED microwave-sensing dimmer provided in the present utility model improves drive control, greatly reduces consumption of energy sources and meets the requirements of energy-saving and environmental protection by combining HF microwave detection with LED drive.
