    摘要: Optical systems are described that have at least one source of a beam of blue light with divergence under 15°. A phosphor emits yellow light when excited by the blue light. A collimator is disposed with the phosphor and forms a yellow beam with divergence under 15°. A dichroic filter is positioned to transmit the beam of blue light to the phosphor and to reflect the beam of yellow light to an exit aperture. In different embodiments, the beams of blue and yellow light are incident upon said filter with central angles of 15°, 22°, and 45°. The filter may reflect all of one polarization and part of the other polarization, and a polarization rotating retroreflector may then be provided to return the unreflected light to the filter.

    摘要: A luminaire has a light source and a shell integrator. The shell integrator has a transparent dome over the light source, with inner and outer surfaces formed as arrays of lenslets. Each lenslet of the inner surface images the light source onto a respective lenslet of the outer surface, and each lenslet of the outer surface images the respective lenslet of the inner surface as a virtual image onto the light source. The dome may be substantially hemispherical. The light source and the integrator may be at an input of a collimator.
