    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: 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.

    IPC: G02B26/00

    Abstract: The examples herein relate to assembly techniques and structures for an electrowetting cell, e.g. a fluid lens, a fluid prism or a single cell that may support both variable lens and variable prism functions. The resulting cell structure, for example, may support both beam shaping and steering functions, e.g. supporting use of the same electrowetting cell structure for a wider variety of optical processing applications. The resulting cell may be used in combination with an optical/electrical transducer or an array of cells may be used with a transducer in systems for a various light input and/or output applications.

    Abstract: A configurable optical device may include an optical transducer, a multi-lens arrangement, and a controllable optical modulator. The optical transducer is configured to convert light to electrical signals or to convert electrical signals to light. The multi-lens arrangement is positioned to redirect at least some of the light to or from the optical transducer. The controllable optical modulator is provided between the multi-lens arrangement and the optical transducer. The controllable optical modulator is coupled to receive and spatially modulate light to or from the optical transducer. The optical modulator is selectively controllable to steer and/or shape the light to a selected distribution of light from the multi-lens arrangement onto the optical transducer and/or from the optical transducer onto the multi-lens arrangement.
