The invention discloses an adjustable-brightness LED strip energy-saving control system with stable performance. The adjustable-brightness LED strip energy-saving control system comprises a single-chip microcomputer, a sound sensor, a brightness sensor, a buzzer, a transistor voltage stabilization filter circuit and a dimming control circuit, wherein the sound sensor, the brightness sensor, the buzzer, the transistor voltage stabilization filter circuit and the dimming control circuit are connected with the single-chip microcomputer. The adjustable-brightness LED strip energy-saving control system further comprises a power supply which is connected with the input end of the transistor voltage stabilization filter circuit, and an LED strip which is connected with the dimming control circuit. The transistor voltage stabilization filter circuit comprises a rectification filter circuit and a DC voltage stabilization circuit which is connected with the rectification filter circuit. The rectification filter circuit comprises a transformer T, a diode rectifier U and a polar capacitor C6. According to the adjustable-brightness LED strip energy-saving control system, a sound wave signal of indoor sound is acquired through a sound sensor, and an indoor ambient brightness signal is acquired through a brightness sensor. Furthermore, through analysis processing of the single-chip microcomputer to the sound wave signal and the brightness signal, automatic brightness adjustment and automatic on-and-off of the LED strip are realized, thereby effectively saving electric power resource.
Description
technical field [0001] The invention relates to the field of electronics, specifically, an energy-saving control system for an LED light strip with adjustable brightness and stable performance. 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 tim...
