Abstract: To improve efficiency, particularly for general illumination applications, a source of green or yellow light includes a solid state device (e.g. a laser diode) to produce an infrared laser beam and a light frequency up-converter to convert the infrared light into green or yellow light. A luminaire includes such a source as well as a source providing two other colors of light, such as red and blue (e.g. not green or yellow). The emitters of the other source may be light emitting diodes or additional laser diodes. The luminaire outputs a combination of the various colors of lights from the sources, for example, to produce white light. If the different emitters are independently controllable, the luminaire may be adjusted or ‘tuned’ to output white light of different color characteristics and/or to output combined light of various colors over a wide region of the visible light color gamut.

Abstract: A tunable luminaire includes a laser light source and at least two different holograms. A beam of light is selectively directed from the laser light source to a first hologram in a first state of the luminaire to enable the luminaire to output light of a first characteristic. A beam of light is selectively directed from the laser light source to a second hologram in a second state of the luminaire to enable the luminaire to output light of a different second characteristic. For example, in the different states, different patterns of light from the holograms pass through and pump different photoluminescent materials, to produce luminaire light outputs in the different states having a different color characteristic. In other examples, in the different states, different patterns of light from the holograms pass through different elements or portions of an optical system to provide light outputs having different distributions.
