Abstract
A lighting apparatus includes a rectifier, a set of light sources and a set of driver modules. The rectifier has a neutral node connected to a neutral wire and a hot node connected to a hot wire for connecting to an external power source. A manual switch is placed between the external power source and the neutral node. The switch controller is connected to the neutral node for detecting an operation of the manual switch among multiple candidate operations. Each candidate operation is associated to a set of control signals. Each driver module has a first end connected to the rectifier and a second end connected to the switch controller for receiving a corresponding control signal to drive one corresponding light source from the set of light sources. The driver module includes a constant current source and a switch unit.
