Patent ID: 8905609

Claim:
A projection apparatus ( 12 , 12 a - b ) comprising: a reflector ( 28 ) configured to reflect electromagnetic radiation emitted from a primary light engine ( 20 ); a projector lens ( 30 ) configured to project at least a portion of said reflected electromagnetic radiation from said reflector ( 28 ); and a shutter ( 24 , 24 a - c ) disposed between a secondary light engine ( 22 , 22 a - b ) and said reflector ( 28 ), said secondary light engine ( 22 , 22 a - b ) being coupled to said shutter ( 24 , 24 a ), said shutter ( 24 , 24 a - c ) configured to selectively obscure a portion of said projector lens ( 30 ) from said reflected electromagnetic radiation, said shutter ( 24 , 24 a - c ) further configured to selectively emit at least a portion of electromagnetic radiation from said secondary light engine ( 22 , 22 a - b ) through at least a portion of said projector lens ( 30 ), said shutter ( 24 , 24 a - c ) further being configured to selectively prevent emission of at least a portion of electromagnetic radiation from said secondary light engine ( 22 , 22 a - b ) through at least a portion of said projector lens ( 30 ) when said shutter ( 24 , 24 a - c ) is not obscuring said portion of said projector lens ( 30 ) from said reflected electromagnetic radiation; wherein when said shutter ( 24 , 24 a - c ) is selectively emitting electromagnetic radiation from said secondary light engine ( 22 , 22 a - b ) through said at least a portion of said projector lens ( 30 ), said secondary light engine ( 22 , 22 a - b ) is disposed below a focal point (F 1 ) of said projector lens ( 30 ).
