Abstract
A reflector spotlight luminaire includes a housing defining an optical axis. The light source is provided that includes one or more white light emitting LEDs, the lights being arranged to direct a beam of white light along the axis of the housing, such as being reflected from an ellipsoidal reflector. An image engine in the form of an LCD panel intercepts the beam of white light traveling along the axis to modify and enhance the beam of white light with image data, such as color, shape, animation, etc. Conventional projection optics accumulates the image emitted by the image engine, projects the optically enhanced light beam through the housing onto a projection surface.
