Signal amplification circuit-based multifunctional control system for LED lamp

Abstract

The invention discloses a signal amplification circuit-based multifunctional control system for an LED lamp. The multifunctional control system is mainly composed of a single chip microcomputer, a power supply, an infrared detector, a brightness sensor, a display, a data memory, an LED lamp, and a triode rectifying, filtering and voltage stabilizing circuit, wherein the brightness sensor, the display, the data memory and the LED lamp are all connected with the single chip microcomputer, and the triode rectifying, filtering and voltage stabilizing circuit is connected between the power supply and the single chip microcomputer in series. The multifunctional control system is characterized in that a signal amplification circuit is also connected between the infrared detector and the single chip microcomputer in series; and the triode rectifying, filtering and voltage stabilizing circuit is composed of a transformer T, a diode rectifier U1, a polar capacitor C1, a voltage detection circuit connected with the diode rectifier U1, and a voltage stabilizing output circuit connected with an output end of the voltage detection circuit. The multifunctional control system for the LED lamp, provided by the invention, can output steady drive current, can realize automatic control on turning on or turning off of the LED lamp, thereby meeting the requirements of people on the LED lamp in the aspects of energy saving and intelligent control.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a multifunctional control system for LED lamps based on a signal amplifying 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 lights currently used by people, and the inability to realize automatic control ...
