Abstract:
A spill light reducer assembly includes at least one light source, at least one reflector, and a spill light reducer plate. The reflector includes a proximal end disposed about one or more corresponding light sources and a distal end extending outwardly from the proximal end. The spill light reducer plate includes at least one opening formed therein, which is positioned a predetermined distance away from the distal opening. The light source emits a main light beam and a spill light beam surrounding the main light beam. The spill light reducer plate reduces the amount of spill light emitted through the opening of the spill light reducer plate. A light fixture includes a housing that defines a cavity and a light emitting window. The spill light reducer plate is disposed within the cavity.
