Patent ID: 7168810

Claim:
An apparatus comprising: a first light emitting device to emit light within a first wavelength range from a plane along a first light path; a second light emitting device to emit light within a second wavelength range from the plane along a second light path; a third light emitting device to emit light within a third wavelength range from the plane along a third light path; first, second, and third optical integrators each having an input aperture to receive light from the respective first, second, and third light emitting devices; and an output aperture to transmit substantially integrated light along the respective first, second, and third light paths; wherein each of the first, second and third optical integrators comprise one of a group consisting of a flyseye-lens integrator and an integrating tunnel; first and second reflecting devices to receive light along the respective first and second light paths and to reflect the light towards an optical combiner; the optical combiner to receive light from the first reflecting device at a first side, the second reflecting device at a second side, and the third light emitting device at a third side, and to transmit light along a fourth light path from a fourth side; and a light valve, having an aspect ratio, optically coupled to the optical combiner to receive light from the optical combiner, and to modulate the light into image bearing light.
