Abstract

The invention discloses an energy-saving control circuit for an LED flashlight belt, which mainly consists of a diode rectifier U1, a control chip U2, a triode VT1, a triode VT2, a triode VT3, a triode VT4, a one-way thyristor VS, a polar capacitor C7, and a resistor R4. composition. The invention suppresses or eliminates the harmonics in the DC voltage, and limits or adjusts the instantaneous high current generated when the DC voltage is loaded, so that the DC voltage is cleaner and more stable, thereby improving the stability of the output voltage of the invention As a result, the present invention can effectively prevent the continuous flickering of the LED flashlight strip LEDW when the brightness changes, effectively prolong the service life of the LED flashlight strip LEDW, and save material resources well.

Description

technical field [0001] The invention relates to an energy-saving control circuit, specifically, an energy-saving control circuit for an LED flashlight belt. 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 flashlights with various light sources to beautify the interior. The LED flash light strips are mostly set in the dark groove on the top of the room, and under the control of the control circuit of the LED flash light strips, a beautiful halo with different brightness is formed. This halo can not only beautify the living environment, but also bring people a wonderful atmosphere at night. sense of fantasy. However, the control circuit of the existing LED flashlight strips has the problem of poor output voltage stability, which causes the LED flashlight strips to ...
