Abstract

The invention discloses a transistor-voltage-stabilizing-filtering-circuit-based energy-saving control system for an LED lamp band. The system comprises a single-chip microcomputer, a sound sensor, a power supply, an LED lamp band, a buzzer, a transistor voltage-stabilizing filter circuit, a signal receiving and processing circuit, a power supply, and a brightness sensor, wherein the sound sensor, the power supply, the LED lamp band, the buzzer, the transistor voltage-stabilizing filter circuit and the signal receiving and processing circuit are connected with the single-chip microcomputer, the power supply is connected with the input terminal of the transistor voltage-stabilizing filter circuit, and the brightness sensor is connected with the signal receiving and processing circuit. The transistor voltage-stabilizing filter circuit consists of a rectifier filter circuit and a direct-current voltage-stabilizing circuit connected with the rectifier filter circuit; and the output terminal of the direct-current voltage-stabilizing circuit is connected with the LED lamp band. According to the invention, the sound sensor is used for sensing an acoustic signal of a sound indoors, the brightness sensor is used for collecting an indoor environment brightness signal, and the single-chip microcomputer is used for analyzing the acoustic signal and the brightness signal, so that automatic adjustment of the brightness of the LED lamp band and automatic turning on or off of the LED lamp band are realized and thus the power resources can be saved effectively.

Description

technical field [0001] The invention relates to the field of electronics, specifically, an energy-saving control system for LED strips based on a transistor voltage stabilizing filter circuit. Background technique [0002] At present, with the continuous improvement of people's living standards, the requirements for the beautification of the living environment are getting higher and higher. In order to beautify their living environment, people use LED light strips with various light source colors to beautify the interior. People often set the LED light strips in the dark groove on the top of the room to form a beautiful halo, which can not only beautify the living environment, but also bring people a wonderful light at night. However, the switch control systems of the existing LED light strips mostly use manually controlled electronic switches, which cannot automatically adjust the brightness of the LED light strips according to changes in indoor brightness. At the same time...
