Abstract
The present disclosure discloses an apparatus for thermally protecting an LED device. The apparatus includes a substrate. The apparatus includes a plurality of light-emitting devices disposed over the substrate. A selected one of the plurality of light-emitting devices is at least partially surrounded by the rest of the plurality of light-emitting devices. The apparatus includes a feedback mechanism electrically coupled to the selected light-emitting device. The feedback mechanism is operable to detect a change in a temperature of the selected light-emitting device. The feedback mechanism is also operable to adjust an electrical current through at least the selected light-emitting device in response to the detected change in the temperature.
