LED lamp light-operated energy saving system based on trilinear drive circuit

Abstract

The invention discloses an LED lamp light-operated energy saving system based on a trilinear drive circuit, mainly comprising a single chip microcomputer; an infrared detector; a first brightness sensor, a second brightness sensor, a power source, a display, a data memory and an LED lamp which are all in connection with the single chip microcomputer; and a signal processing amplification circuit which is in series connection between the infrared detector and the single chip microcomputer, and characterized in that a trilinear drive circuit is in series connection between the single chip microcomputer and the LED lamp. The signal processing amplification circuit is composed of a signal conversion circuit in connection with the infrared detector, and a single filtering amplification circuit in connection with the signal conversion circuit. The system can output stable driving current, automatically adjust LED lamp brightness according to ambient brightness change, and automatically turn on or off the LED lamp, thereby meeting people requirements on LED lamp energy saving performance, and satisfying intelligent control requirements.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a light-control energy-saving system for LED lamps based on a trilinear drive circuit. Background technique [0002] At present, as a new type of energy-saving light source, LED lights have been widely accepted and adopted by people due to their environmental protection, energy saving, long life, and small size. With the continuous improvement of people's living standards, higher requirements are put forward for the brightness and energy consumption of LED lights, whether at home or in stores, that is, people need to further increase the brightness of LED lights while requiring LED lights to have lower energy consumption. , and can intelligently control the use of LED lights. [0003] However, due to the poor stability of the control system and the unstable output drive current of the LED lamps currently used by people, the brightness of the LED lamp cannot be adjus...
