    Abstract: A ultraviolet (UV) intensity indicator might use a UV responsive lumiphore to provide a converted, visible light level proportional to received UV light intensity for comparison to a visible brightness reference. For a desired UV intensity, the converted light should normally appear at least as bright as the reference light. For undesired UV, e.g. in a harmful wavelength range, the converted light should appear dimmer than the reference for normal operation and/or appear as bright as or brighter than the reference during excessive emission of the potentially hazardous UV emission. Alternatively, saturable lumiphores may provide different color outputs responsive to UV intensities for comparison to a multi-colored reference. Other examples contemplate use of a lumiphore to convert UV light to provide a visible light input to a visible light meter, such that an illuminance or brightness measurement by the meter gives a proportional representation of intensity of the UV light.

    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 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: The examples relate to various implementations to enable simultaneous controllable lighting distribution and a wide angle image light output from areas of a luminaire. An example of such a luminaire includes image light emitters and an array of general illumination light emitters for general illumination. A grid structure that has a supporting grid of rows and columns with intersection points and transparent sections or gaps is used to maintain a spaced arrangement of the general illumination light emitters and the image light emitters. Each of the transparent sections is bounded by individual structural members of the grid meeting at individual intersection points. In a specific example, image light emitters are located at intersection points of the grid structure. The general illumination light emitters are optically coupled for emitting general illumination light through the transparent sections of the grid.

    Abstract: The disclosed examples relate to various implementations of a micro-light emitting diode upon which is built a controllable variable optic to provide a chip-scale light emitting device. An example of the controllable variable optic described herein is a controllable electrowetting structure having a leak-proof sealed cell with a first fluid having a first index of refraction and a second fluid having a second index of refraction. The controllable electrowetting structure may be integrally formed on or in a substrate or semiconductor material associated with the micro-light emitting diode in alignment with one or more of the light emitting diodes of the micro-LED device to provide a controllable lighting distribution.
