Illumination system having a plurality of light source modules disposed in an array with a non-radially symmetrical aperture

An illumination system, comprising:

• a plurality of light source modules disposed in an array within a non-radially symmetrical aperture;
• an illumination target;
• and
• a system of optical elements disposed between the plurality of light source modules and the illumination target,
• wherein the illumination target is an image-forming device having a plurality of mirrors rotatable about a pivot axis, and wherein the non-radially symmetrical aperture has a long dimension and a short dimension and is oriented so that the long dimension is aligned with the pivot axis of the mirrors of the image-forming device.

An illumination system, comprising:

• a plurality of light source modules disposed in an array within a non-radially symmetrical aperture, each light source module comprising a light-emitting surface;
• an image-forming device;
• and
• a system of optical elements disposed between the plurality of light source modules and the image-forming device;
• wherein the system of optical elements images the emitting surfaces of the light source modules onto the image-forming device.

An illumination system comprising:

• a plurality of light source modules disposed in an array within a non-radially symmetrical aperture, each light source module comprising a light-emitting surface;
• a light tunnel having an entrance;
• and
• a system of optical elements disposed between the plurality of light source modules and the light tunnel,
• wherein the system of optical elements images the emitting surfaces of the light source modules onto the entrance of the light tunnel, and the system decreases etendue degradation.
