Patent ID: 7626153

Claim:
A system for controlling light emitted from a light source in an environment having ambient light, the system comprising: an LED to emit light wherein the light emitted from the LED has an intensity wherein the LED has an emitting surface to transmit the light emitted from the LED wherein the emitting surface of the LED has a finish wherein the finish of the emitting surface of the LED retards reflection of the ambient light from the emitting surface of the LED and further wherein the finish of the emitting surface of the LED allows the light emitted from the LED through the emitting surface of the LED to pass through the finish and into the environment; a detector adjacent to the LED to detect the intensity of the light emitted directly from the emitting surface of the LED; a control circuit for monitoring the intensity of the light detected by the detector wherein the control circuit is electrically connected to the detector and the LED wherein the control circuit regulates the intensity of light emitted by the LED; and a tower having an internal compartment that surrounds the detector wherein the tower prevents exposure of the detector to the ambient light wherein the tower has an external surface and a pathway wherein the pathway is located between the detector inside the internal compartment and the external surface to transmit the light emitted directly from the emitting surface of the LED to the detector in the compartment.
