    摘要： A luminaire (12, 400) including an LED light source (550), a plurality of color filters (513, 514), an optical device (402, 404, 406), and a control system (600) is provided. In response to receiving an optical device setting value via a data link (14), the control system (600) moves the optical device (402, 404, 406) according to the setting value, calculates modified positions for one or more of the color filters (513, 514) based on an effect of the optical device (402, 404, 406) on the color of the light beam of the luminaire (12, 400), and causes the one or more color filters (513, 514) to move to their modified color filter positions, in order to reduce the effect of the optical device (402, 404, 406) on a beam color emitted by the luminaire (12, 400).

    摘要： A display system comprising a light emitter; a reflector optically coupled to the light emitter and configured to receive light from the light emitter, the reflector configured to output light with increased angular uniformity relative to light received from the light emitter, a lens coupled to the reflector and configured to receive light from the reflector, the lens configured to output light with increased spatial uniformity relative to light output from the reflector; a spatial light modulator configured to receive light from the lens and to modulate the light received from the lens to create an image; and a stack of waveguides, wherein each waveguide of the stack comprises a light incoupling optical element configured to incouple light from an associated light emitter, wherein the spatial light modulator is configured to provide light from the associated light emitter to the waveguide.
