    Abstract: An example lighting device includes a luminaire having a miniature illumination light source matrix including miniature illumination light sources configured to be driven by electrical power to emit incoming light rays for illumination lighting. Luminaire further includes an optical lens sheet positioned directly over and abutting the miniature illumination light source matrix and configured to extend over the illumination light source matrix and including an input surface coupled to receive the incoming light rays and an output surface lens array. Input surface is a substantially planar lateral surface extending across an entirety of the miniature illumination light source matrix. Output surface lens array includes a plurality of miniature optical lenses, including a respective miniature optical lens for each of the miniature illumination light sources to refract the incoming light rays into an outputted beam pattern of output light rays for the illumination lighting.

    Abstract: Disclosed are examples of optical/electrical devices including a variable TIR lens assembly having a transducer, an optical lens and an electrowetting cell coupled to an exterior wall of the lens. The electrowetting cell contains two immiscible liquids having different optical and electrical properties. One liquid has a high index of refraction, and the other liquid has a low index of refraction. At least one liquid is electrically conductive. A signal causes the high index of refraction and the low index of refraction liquids to assume various positions within the electrowetting cell along the exterior wall. The properties of the optical lens, e.g. its total internal reflectivity, change depending upon the position of the respective liquids along the exterior wall. The light detection characteristics of the assembly change to receive an input light beam over a range of inputs or over a range of fields of view.

    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.
