Abstract
A lamp includes a light source in a top of a housing, the light source including a driver, a light emitting member electrically connected to the driver, and a dimming controller electrically connected to the driver wherein the driver is configured to activate the light emitting member after being activated by a signal sent from the dimming controller; and an electro-optical sensor in the top of the housing and electrically connected to the dimming controller wherein light emitted by the light emitting member is reflected to the electro-optical sensor, and the electro-optical sensor sends the sensed light to the dimming controller. The dimming controller compares intensity of the sensed light with intensity of the light emitted by the light emitting member, and the driver either decreases the intensity of the light output or increases same based on the comparison.
