Embodiment Construction

[0033] Such as figure 1 As shown, a power carrier communication LED control circuit includes a control module 10, a drive module 20 and an LED module 30, the control module 10 includes an MCU and a voltage adjustment module, and the MCU outputs data control signals for controlling the LED module to the voltage adjustment Module, the voltage adjustment module modulates the data control signal, converts the data control signal into high and low levels, and uses a combination of high level for T1 time and low level for T2 time to represent binary code 1, and low level for continuous The combination of T1 time and high level continuous T2 time represents binary code 0, the high level takes the power supply voltage of the voltage adjustment module, and the low level takes any value lower than the power supply voltage value of the voltage adjustment module. In this embodiment, the low power Take half of the power supply voltage value of the voltage adjustment module, and apply the h...

Abstract

The invention discloses a power carrier communication LED control method comprising the following steps: A1. A control module generates an LED data control signal and modulates the data control signal, and applies the modulated data control signal to the power supply of the drive module Voltage; A2, drive module, including address setting terminal and LED output terminal, with the modulated data control signal as power input, the power supply voltage is demodulated to obtain the data control signal, according to the data control The signal controls the LED light to work, and the electrical method only needs two wires to realize the control of multiple LED modules and realize complex and beautiful flickering effects.

Description

technical field [0001] The invention relates to the field of LED control, in particular to a power carrier communication LED control driving method. Background technique [0002] Christmas lights are decorations commonly used on Christmas trees in Western countries. Use the control circuit to realize trick effects such as flowing water and flickering, creating a better festive atmosphere. In addition to household use, shops, streets, etc. are also widely used. At present, it is also used more and more in China. [0003] The components of Christmas lights are mainly several strings of lights and a control box. Because everyone has different preferences, generally several different flashing patterns are provided for the user to choose, and the patterns can be switched by a button on the control box. The most common Christmas light control circuit on the market is a four-way eight-segment control that provides eight flashing pattern options. Usually only some basic flashin...
