ABSTRACT:
A control circuit used in a lamp system. The lamp system has a first and a second light emitting diode (LED) connected together in series. The control circuit includes a current source for connecting to the first LED to provide a regulated drive current to the first and second LEDs in order to illuminate the LEDs. The control circuit includes a switching component for connecting in parallel with the first LED to divert the driver current from the first LED and provide the driver current to the second LED when the switching component is activated. The control circuit includes a controller for selectively activating the switching component in order to selectively extinguish the first LED.
