Abstract: Lighting devices are disclosed. One lighting device includes a housing, a light source, and a panel. The light source is mounted within the housing and configured to emit light sufficient for general illumination of an area. The panel is supported by the housing at a location to receive light from the light source at one or more light input surfaces of the panel and output the received light from the light source via a light output surface of the panel facing the area. The light propagates within material of the panel from the one or more light input surfaces to the light output surface. The light output surface of the panel comprises a noise reduction structure.

Abstract: An example lighting device has a luminaire. The luminaire includes an illumination light source matrix including illumination light sources configured to be driven by electrical power to emit light rays for illumination lighting. The luminaire further includes an optical lens positioned and configured to extend over the illumination light source matrix and including an input surface coupled to receive incoming light rays emitted by the illumination light sources and an output surface. Both the input surface and the output surface each include various portions to refract or total internally reflect the incoming light rays emitted by the illumination light sources passing through to shape or steer the illumination lighting into an outputted beam pattern. A coupled illumination light source driver selectively controls the illumination light sources individually or in combination to adjust the outputted beam pattern from the optical lens.

Abstract: An example lighting device has a luminaire. The luminaire includes a laser light source configured to be driven by electrical power to emit laser light rays, a phosphor plate, and a solid medium freeform prism or waveguide. The solid medium freeform prism or waveguide confines incoming laser light ray emitted from the laser light source inside the solid medium until conversion into illumination lighting by the phosphor plate. The solid medium includes an input surface or lens coupled to the laser light source, an output surface, and a highly reflective internal surface to reflect laser light rays to propagate inside the solid medium until emission through the output surface. The phosphor plate is coupled to the output surface of the solid medium to convert the reflected laser light rays into the illumination lighting to emit from the luminaire.

Abstract: An example lighting device has illumination light sources, each configured to be independently driven. The device further includes an optical lens positioned over the illumination light sources. The optical lens has a number of aspheric or spheric convex surfaces, including an input surface and an output surface. The input surface includes an input peripheral portion and an input central portion. The input peripheral portion extends from the illumination light sources and curves from a region of the illumination light sources towards the input central portion. The input central portion curves towards the illumination light sources. The output surface includes an output lateral portion, an output shoulder portion, and an output body portion. Another example uses optical-to-electrical transducers, e.g. light detector or photovoltaic devices, in combination with the optical lens, for light reception transducer applications.

The luminaire further includes an optical lens positioned and configured to extend over the illumination light source matrix and including an input surface coupled to receive incoming light rays emitted by the illumination light sources and an output surface. Both the input surface and the output surface each include at least two different aspherical, spherical, or planar portions to refract the incoming light rays emitted by the illumination light sources passing through to shape or steer the illumination lighting into an outputted beam pattern. A coupled illumination light source driver selectively controls the illumination light sources individually or in combination to adjust at least a beam angle of the outputted beam pattern from the optical lens.

Abstract: An example luminaire includes a laser light source, a photoluminescent material and a holographic optical element. The holographic optical element has a hologram optically coupled to the laser light source and to the photoluminescent material. The hologram is configured to distribute light received from the laser light source as a pattern of light to the photoluminescent material.

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.
