Abstract
A lighting system (10) comprising a primary light engine (20); a secondary light engine (22); and a projection apparatus (14, 14a-b) comprising a reflector (28) configured to reflect electromagnetic radiation emitted from the primary light engine (20); a projector lens (28) configured to project at least a portion of the reflected electromagnetic radiation from the reflector (28); and a shutter (24, 24a-c) disposed between the secondary light engine (22) and the reflector (28). The shutter (24, 24a-c) is configured to selectively obscure a portion of the projector lens (28) from the reflected electromagnetic radiation and is further configured to selectively emit at least a portion of electromagnetic radiation from the secondary light engine (22) through at least a portion of the projector lens (28).
