ABSTRACT:
A light emitting device has a light emitting diode (LED), a reflector cup, and one or more adjustment mechanisms to control the intensity profile of light emitted from the light emitting device. The reflector cup has a base and a sidewall extending outward from the base. A base adjustment mechanism controls the total amount of light reflected from the base and into the beam of light emitted from the light emitting mechanism by controlling the aggregate reflectivity of the base. A sidewall adjustment mechanism controls the angle of the sidewall relative to the base. A vertical adjustment mechanism vertically raises or lowers the LED relative to the base.
