Multi-channel control method for light strip

A lighting device, comprising:

• a substrate;
• a controller mounted on one end of the substrate, including m channels of outputs;
• a driver configured to provide n channels of modulated signal to the controller via n wires, comprising a communication module configured to receive control signal, wherein the driver is configured to generate the n channels of modulated signal based on the control signal;
• and
• a plurality of lighting units coupled to the m channels of outputs of the controller,
• wherein n is less than m,
• wherein the n wires are aligned along a width direction of the substrate at the end of the substrate,
• wherein the controller is configured to gate the m channels of outputs based on a correspondence between the at least one of the characteristics of the n channels of modulated signal and m channels of output signal, and
• wherein the characteristics are selected from a group consists of voltage, current and a combination thereof.
