Abstract
A lighting device is disclosed. The example lighting device includes a printed circuit board. First and second LED circuits are mounted on the printed circuit board. The first LED circuit is configured to emit a first color temperature of white light when receiving power from a driver circuit and the second LED circuit is configured to emit a second color temperature of white light when receiving the power from the driver circuit. The second color temperature of white light emitted from the second LED circuit is different than the first color temperature of white light emitted from the first LED circuit.
Claims20
A lighting device comprising:
- a driver circuit and a first LED circuit mounted on a printed circuit board, the first LED circuit configured to receive power provided from an output of the driver circuit, the first LED circuit including a first plurality of LEDs, wherein the first LED circuit is configured to emit a first color temperature of white light when receiving the power from the driver circuit;
- a second LED circuit mounted on the printed circuit board, the second LED circuit configured to receive power provided from the output of the driver circuit, the second LED circuit including a second plurality of LEDs, wherein the second LED circuit is configured to emit a second color temperature of white light when receiving the power from the driver circuit, the second color temperature of white light being different than the first color temperature of white light emitted from the first LED circuit;
- and
- a switch configured for user control,
- wherein the switch is configured to control a level of the power received by the first LED circuit and the second LED circuit based upon a user-selected position of the switch, and
- wherein the first LED circuit and the second LED circuit are configured to change brightness levels of light emitted in response to the user changing the position of the switch.
