A controller for controlling a light source module including a first LED array and a second LED array includes a first driving terminal and a second driving terminal. The controller is operable for turning on a switch between a power converter and the first LED array by the first driving terminal to deliver electric power from the power converter to the first LED array in a first sequence of discrete time slots, and for turning on a second switch between the power converter and the second LED array by the second driving terminal to deliver electric power from the power converter to the second LED array in a second sequence of discrete time slots, where the first sequence of discrete time slots and the second sequence of discrete time slots are mutually exclusive.
