Abstract

The invention discloses a power line edge signal triggered colored lamp device with a broadcast address signal. The device comprises a power line edge signal generator which generates an address signal and a light control signal and loads the address signal and the light control signal to a power line; a plurality of LED modules, wherein each LED module comprises an LED colored lamp group and an LED driver for driving the LED colored lamp group according to the address signal and the light control signal. The plurality of LED modules comprise two or more than two LED driver address codes; when the address signal is a non-broadcast address signal, the LED driver receives the address signal and the light control signal, and when the address signal is equal to the address code of the LED driver, the light control signal is responded, and the LED colored lamp group is driven according to the light control signal; and when the address signal is a broadcast address signal, the plurality of LED modules respond to the light control signal at the same time, and the LED colored lamp group is driven according to the light control signal. The colored lamp device solves the problem of shaking when all light needs to be changed at the same time, and the overall light effect is improved.

Description

technical field [0001] The invention relates to the field of LED colored lights, in particular to a colored light device triggered by an edge signal of a power line with a broadcast address signal. Background technique [0002] At present, there are "arithmetic operation device and LED driver triggered by power line edge signal" and Chinese invention patent "color lamp device based on power line edge signal control" (Chinese invention patent ZL201410632645.7, Chinese invention patent ZL201410775449.5) , due to its high cost performance, this patented technology has achieved large-scale industrial application. [0003] The control signal is transmitted through the power line to realize the multi-color control lantern device that only needs the power line and the ground line and does not need additional control signals. The light-emitting diode and the power line carrier control chip are packaged together to form a controllable color light-emitting module with the same shape ...
