Abstract

See full text

An apparatus includes a light-emitting diode (LED) driver circuit, one or more LEDs of an LED array, and an electronic switching circuit. The LED driver circuit is configured to generate an electric current. The one or more LEDs are electrically connected to the LED driver circuit. The electronic switching circuit is electrically connected to the one or more LEDs and configured to be placed in one of multiple switching configurations. The electronic switching circuit is further configured to direct a portion of the electric current away from the one or more LEDs, such that a remaining portion of the electric current drives the one or more LEDs. The portion of the electric current corresponds to the one of the multiple switching configurations.
