Title:

COLOURED LAMP APPARATUS BASED ON EDGE SIGNAL CONTROL OVER POWER LINE

Document Type and Number:

WIPO Patent Application WO/2016/095648

Kind Code:

A1

Abstract:

Provided is a coloured lamp apparatus based on edge signal control over a power line. The coloured lamp apparatus comprises a plurality of light emitting diode (LED) coloured lamp banks, and further comprises: an edge signal generator, used for generating an edge signal and loading the edge signal to a power line to be output; and LED drivers which are in one-to-one correspondence to the LED coloured lamp banks, and are used for driving the corresponding LED coloured lamp banks according to the edge signal output by the power line. The LED coloured lamp apparatus in the present invention controls the power line to be switched on and off by controlling a controllable switch to be turned on and off, further outputs the edge signal, and loads same on the power line. Each LED coloured lamp bank and the corresponding LED driver are directly connected to the power line loaded with the edge signal, such that LED coloured lamps can be driven, and different coloured lamp effects are achieved. The circuit structure is simple, and has low costs, and extremely rich decoration effects can be achieved by micro control unit (MCU) programming.
