Abstract: A colored light apparatus controlled by input edge signals from a power supply line includes a signal edge generator configured to generate signal edges and output the signal edges to a power supply line; a plurality of LED modules each including an LED group, and an LED driver to drive the LED group based on the signal edges from the power supply line. The LED modules are electrically connected between a common anode and a common cathode. The controllable switch module is turned between ON and OFF controlled by the control circuit of said signal edge generator. Signal edges are generated when the controllable switch module turns from ON to OFF, or the controllable switch module turns from OFF to ON.
