Definitions

  • An illumination system for illuminating a target area includes an LED source, a light mixer, a collection lens that collects light from the LED source, and an image- forming device positioned at the target area.
  • the LED source includes a mosaic of LED dies forming a footprint of at least two different colors.
  • FIG. 1 is a schematic diagram of a projection subsystem.
  • FIG. 2A illustrates a projection subsystem 200.
  • Projection subsystem 200 is similar to projection subsystem 100 except that an anamorphic optical device 202 is included in the projection subsystem 200.
  • Reference numbers used in FIG. 2 A that are the same as reference number used in FIG. 1 represent the same or similar features.
  • the projection subsystem 200 is similar to projection subsystem 100.
  • the anamorphic optical device 202 alters an aspect ratio of a light beam 204.
  • the anamorphic optic device 202 changes light beam shape to adapt a first aspect ratio in the light engine 102 to a second different aspect ratio in the refractive body 120. In one embodiment, the first aspect ratio is 1 :1 and the second aspect ratio is 16:9.
