Abstract
A colorful light apparatus controlled by input edge signals from a power supply line includes a plurality of LED group, an edge signal generator configured to generate edge signals and output edge signals to the power supply line, and LED drivers configured to drive LED groups based on the edge signals from the power supply line corresponding to each LED group. The edge signal is generated by the controllable switch switching between on and off based on output signals of a control circuit, and is carried to the power supply line. The LED modules are configured to be driven to obtain a plurality of lighting modes, wherein each LED module and its drivers can be connected to the power supply line directly. The structures of the circuits are simple and of low cost. Moreover, various effects of decorations can be achieved by programming using a Microprocessor Control Unit (MCU).
