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.
