AC lighting system with a control unit for controlling power of an LED
An AC light system with a control unit for controlling power of an LED is disclosed. According to one embodiment, a driver circuit for driving LEDs has a plurality of current sinks, a first interface configured to receive an AC power from an AC power source, a second interface to a plurality LED groups. The driver circuit further has a third interface configured to receive a control input from a control unit. Each current sink of the plurality of current sinks controls an LED current flowing through a corresponding LED group based on the control input from the control unit.
