Abstract

The invention provides a color lamp device controlled based on the edge signal of the power line, which includes an edge signal generator for generating the edge signal and loading the edge signal on the power line for output; several LED modules, each LED The module includes an LED colored light group and an LED driver for driving the LED colored light group according to the edge signal output by the power line; several LED modules are electrically connected to form a common anode of the LED module and a common cathode of the LED module; the edge The signal generator includes a controllable switch module and a control circuit; the controllable switch module includes a switch module control terminal electrically connected to the control circuit, a switch module input terminal electrically connected to the common cathode of the LED module, and a ground connection output of the switch module. The colored light device can control the on and off of the controllable switch module, control the on-off of the power line, and then output the edge signal and load it on the power line, so as to complete the drive of the LED colored light and realize different colored light effects. , the circuit structure is simple.

Description

technical field [0001] The invention relates to the technical field of LED control, in particular to a colored lamp device controlled by an edge signal of a power line. Background technique [0002] At present, the LED lanterns on the market have a constant light mode and a flashing light mode. The constant light mode is easy to manufacture, but the decorative effect is monotonous. The main implementation methods of strings with flashing lights include: install LED flashing bulbs at intervals in the string of constant lights, but the lighting mode of this LED flashing bulbs is fixed, and it cannot receive control signals to achieve other changing effects: another way is to use LED colored lights Divided into several groups, each LED lantern is controlled by a separate controller. In order to achieve the effect of light string and flowing water, it must be made into a structure of more than 3 channels. The more channels, the better the effect. [0003] In the mode of dividi...
