Abstract
A projection display composed of a plurality of tiles (101) is illuminated by a plurality of projectors (400), one for each tile. The light from a plurality of light engines (200) is combined in a homogenizer to form a common illumination source which is then separated by a light separation unit (300) into individual primary colors. The individual primary colors are then transmitted over a second set of fiber optic cables (502) to the individual projectors.
Claims14
A projection display system for a projection display composed of a plurality of individual tiles, said system comprising:
- (a) an illumination source producing light;
- (b) a homogenizer;
- (c) first fiber optic cables for transmitting the light from said source to said homogenizer, wherein each of the first fiber optic cables is connected to said homogenizer with a round-to-square morphing collimator;
- (d) a light separation unit for separating light into a plurality of individual component colors, wherein said light separation unit is adapted to receive light from said homogenizer;
- and
- (e) a plurality of projectors, wherein each of said projectors is associated with one of the tiles of the display and is adapted to receive the individual colors of the light from said light separation unit.
A projection display system for a projection display composed of a plurality of individual tiles (101), said system comprising:
- (a) an illumination source comprising of a plurality of light engines (200) each producing a separate plurality of light outputs, wherein each of said light engines further comprises,
- (i) a high-intensity lamp (201) producing the separate light output;
- (ii) a plurality of apertures (203);
- and
- (iii) a plurality of mirrors reflecting the light produced by the high-intensity lamp to thereby cause said light to exit through said apertures;
- (b) a homogenizer (307) adapted to combine multiple light inputs;
- (c) a first plurality of fiber optic cables (501) for transmitting light from said illumination source to said homogenizer;
- (d) a plurality of morphing collimators (307), wherein each of said morphing collimators is mechanically adapted to connect a corresponding one of said first plurality of fiber optic cables to said homogenizer and is optically adapted to substantially collimate light passing through said morphing collimator;
- (d) a light separation unit (300) for separating light into a plurality of individual component colors, wherein said light separation unit is adapted to receive light from said homogenizer;
- (e) a plurality of projectors (400), wherein each of said projectors is associated with one of the tiles of the display and is adapted to receive the individual component colors of the light from said light separation unit;
- (f) a second plurality of fiber optic cables (502) for transmitting the individual component colors from said light separation unit to said projectors;
- (g) a plurality of morphing concentrators (306), wherein each of said morphing concentrators is mechanically adapted to connect a corresponding one of said second plurality of fiber optic cables to said homogenizer and is optically adapted to substantially concentrate light passing through said morphing concentrator;
- and
- (h) wherein each of said projectors includes an imaging device for modulating the individual component colors and a projection lens for projecting the light onto a corresponding tile of the display.
