CONTROLLER, LIGHT SOURCE DRIVING CIRCUIT AND METHOD FOR CONTROLLING LIGHT SOURCE MODULE
First Claim
1. A controller operable for controlling a light source module, said controller comprising:
- a current input terminal, coupled to a power source through a rectifier, operable for receiving electric power from said power source;
a switch monitoring terminal, coupled to a power switch, operable for receiving a switch monitoring signal indicating the on/off state of said power switch, wherein said power switch is coupled between said rectifier and said power source;
a first control terminal, operable for turning on a first light source in said light source module and operable for turning off said first light source, based on said switch monitoring signal;
a second control terminal, operable for turning on a second light source in said light source module and operable for turning off said second light source, based on said switch monitoring signal; and
a current monitoring terminal, operable for monitoring a current flowing through said first light source and a current flowing through said second light source.

Abstract
A controller includes a current input terminal, a switch monitoring terminal, a first control terminal, a second control terminal and a current monitoring terminal. The current input terminal is coupled to a power source through a rectifier and receives electric power from the power source. The switch monitoring terminal is coupled to a power switch and receives a switch monitoring signal indicating the on/off state of the power switch. The power switch is coupled between the rectifier and the power source. Based on the switch monitoring signal, the first control terminal turns on or turns off a first light source in a light source module and the second control terminal turns on or turns off a second light source in the light source module. The current monitoring terminal monitors a current flowing through the first light source and a current flowing through the second light source.
