Patent ID: 7935916

Claim:
A method for controlling light emitted from a light source in an environment having ambient light, the method comprising the steps of: providing a first light intensity detector, an LED having an emitting surface to transmit light emitted from the LED, a control circuit and a housing wherein the housing is located in a position adjacent to the LED wherein the first light intensity detector is located in a position within the housing and further wherein the LED is located in a position outside of the housing wherein the housing has a pathway for allowing the light emitted directly from the LED to reach the first light intensity detector wherein the pathway extends through the housing and further wherein the pathway extends from a position adjacent to the first light intensity detector to a position adjacent to the LED wherein the control circuit is electrically connected to the first light intensity detector and the LED; preventing the ambient light from reaching the first light intensity detector wherein the housing prevents the ambient light from reaching the first light intensity detector; detecting an intensity of the light emitted directly from the LED through the pathway onto the first light intensity detector; and adjusting the intensity of light emitted from the LED.
