Patent ID: 8436287

Claim:
A system for controlling light emitted from a light source, the system comprising: a compartment having ambient light wherein one end of the compartment is defined by a platform; an aperture in the platform; a cap having a first end and a second end wherein the second end is located in a position opposite to the first end and further wherein the first end of the cap is connected to the platform; a cavity in the cap wherein the platform and the aperture are located between the cavity and the compartment; an LED that emits light wherein the LED is located in the cavity and further 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; a first detector located in the cavity wherein the platform is located between the compartment and the first detector wherein the first detector is adjacent to the LED to detect the intensity of the light emitted directly from the emitting surface of the LED and further wherein the compartment prevents the first detector from exposure to the ambient light; and a control circuit for monitoring the intensity of the light detected by the first detector wherein the control circuit is electrically connected to the first detector and the LED wherein the control circuit regulates the intensity of light emitted by the LED.
