Abstract

A lighting device and a lighting system having reversed biased LEDs are disclosed. In an example, a lighting system includes a driver integrated circuit configured to output a DC voltage and at least one LED circuit having at least two LEDs. The at least one LED circuit is electrically configured so that a first LED in the at least one LED circuit is electrically connected to and forward biased by the driver integrated circuit and a second LED in the at least one LED circuit is electrically connected to and reverse biased by the driver integrated circuit. The lighting system also includes a switching circuit configured to switch a biasing of the first LED and the second LED in the at least one LED circuit after receiving a signal from a sensor.
