Abstract
A lighting system and method controls light to prioritize different elements of the beam of light that is output by a fixture. The LCD surface acts as a color occlusion filter that provides pixel level control of the beam of light transmitted by this layer. Internally an LED source is projected perpendicular to concave type reflector which can be moved on one axis and thus zoom to either widen or narrow the light emitted forward as a beam of light. The system also includes certain cooling features.
