Abstract

The invention relates to an LED lamp control system, in particular to a color-changing LED lamp control system and a control method. The system includes an AC power input unit with an input terminal (AC1) and an input terminal (AC2), a micro-processing unit MCU, and a current-limiting and voltage-stabilizing circuit connected between the power input unit and the micro-processing unit MCU, and connected to the power input unit. The sampling circuit between the micro-processing unit MCU, the function selection unit connected to the micro-processing unit, the dual-channel half-wave rectification drive circuit connected between the power input unit and the micro-processing unit MCU, and the dual-channel half-wave rectification drive circuit control The lighting, extinguishing and color control transformation of LED lamps connected between the two output terminals of the dual-way half-wave rectification drive circuit. Another solution of the present invention is to provide a method for controlling the color-changing LED lamp to emit light of three colors through one output.

Description

technical field [0001] The invention relates to an LED lamp control system, in particular to a color-changing LED lamp control system and a control method. Background technique [0002] Decorative lights are often used in daily life, especially in festivals, LED light strings of various colors are widely used in celebrations and building decorations as well as Christmas lights. These LED light strings that can change into n colors, the traditional dynamic control method is to output n channels from a controller, and directly control n channels of LED light strings of various colors to change into n colors. That is, if the dynamic change of the three colors is to be realized, the traditional technical solution requires the controller to output three channels. This method not only increases the consumption of materials, but also brings certain difficulties to production and processing. Contents of the invention [0003] The purpose of the present invention is to overcome t...
