Abstract: A lighting system may include a control unit with a color synthesizer and a lighting device including an LED board within an optical chamber. The LED board may include a first string of LEDs and a second string of LEDs. Each of the control unit and the LED board may be configured to electrically couple to a first wire and a second wire. The strings of LEDs may be structured to emit light having different spectral power distributions within the visible spectrum. The control unit is operable to alternate forward biasing current between the first wire and first string, and between the second wire and the second string LEDs at a frequency configured to emit light having a perceived third color responsive to a color indicated by the color synthesizer.

Abstract: Embodiments of the present invention are related to a lighting system comprising a control unit that manages a lighting device with an LED board within an optical chamber. The LED board includes a first string of LEDs and a second string of LEDs. The control unit and the LED board are configured to electrically couple to first and second wires. The first string of LEDs and the second string of LEDs are configured to emit light having different spectral power distributions within the visible spectrum. The first string of LEDs is oriented in an electrically opposite direction than the second string of LEDs. The control unit comprises a switch configured to direct current between the first wire and second wire. The wire to which current is directed is designated active. The designated active wire activates one of the first string of LEDs and second string of LEDs.
