Abstract: The examples relate to various implementations of a software configurable luminaire and a transparent display device for use in such a luminaire. The luminaire is able to generate light sufficient to provide general illumination of a space in which the luminaire is installed and provide an image display. The general illumination is provided by additional light sources and/or improved display components of the transparent display device.

Abstract: Examples of a lighting and display type luminaire use relatively transparent lighting devices. In such a luminaire, a light transmissive element of the lighting device is coupled to an output of a display device. For example, an edge lit lighting device includes an optical waveguide and one or more illumination light sources coupled to supply light to/through a surface along an edge or periphery of the waveguide. The waveguide allows emission of illumination light through a front surface. A display is coupled to a back surface of the waveguide. During display operations, the waveguide is sufficiently transparent to allow image display light to pass through the waveguide for emission through the front surface of the waveguide. Another example utilizes a light transmissive OLED (organic light emitting diode) panel as the relatively transparent lighting device.

Abstract: The examples relate to various implementations of a software configurable lighting device, installed as a panel, that offers the capability to appear like and emulate a variety of different lighting devices. Emulation includes the appearance of the lighting device as installed in the wall or ceiling, possibly, both when lighting and when not lighting, as well as light output distribution, e.g. direction and/or beam shape.

Abstract: Examples relate to a method and implementations of general illumination light emitters, an image display device and an image diffuser in a luminaire. The image display device is configured to output an image having a reduced, or first, pixel image fill factor and, as a result, might appear pixelated. To mitigate the pixelation, the image diffuser has a predetermined image diffusion angle and is a predetermined distance from the image display device. The image diffuser outputs an image having a second image pixel fill factor that is greater than the first image pixel fill factor. The appearance of the outputted image appears to be formed from fuzzy pixels. Characteristics related to the image, device, diffuser, and their arrangement may be optimized to provide the fuzzy pixels. A luminaire may output an image formed of the fuzzy pixels and general illumination lighting to an area.

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: In a liquid crystal type variable beam shaping optic, a part of a structure that forms a gap for the liquid crystals includes a surface relief micro-structure diffuser. Due to the micro-features of the diffuser, the gap is non-uniform. A voltage applied to an electrode associated with the diffuser and an electrode associated with an opposing substrate controls the orientation of uniaxial nematic liquid crystals in a material filling the non-uniform gap. For example, the index of refraction of the material may vary relative to an index of refraction of the diffuser, based on variations of the crystal orientation caused by variation of the applied voltage. The change in relative indices of refraction, in the examples, changes a focal length of the variable optic and thus the shape of a light beam optically processed through the liquid crystal optic.

Abstract: A luminaire includes a light waveguide grid including an array of waveguides coupling respective illumination light source emitters of a general illumination device with respective gaps between respective pixel light emitters of an image display device. Each waveguide has a housing that includes an input interface optically coupled to the respective illumination light source emitter to steer illumination lighting from the illumination light source emitter. The housing also includes an output interface opposing the input interface and optically coupled to one or more gaps between pixel light emitters. The housing further includes at least one reflective wall having an internal reflective surface encompassing and extending from the input interface and the output interface. The structure of the waveguide may be optimized and/or additional technologies added to reduce optical losses and improve overall illumination efficiency of the luminaire.

Abstract: A plurality of networked lighting devices are deployed in a parking garage. The lighting devices each have a display, a controllable general illumination light source, and an occupancy sensor. When a user enters the parking garage in a vehicle, the display of lighting devices outputs directional arrows and communicates with other lighting devices to direct the user to a vacant parking space (e.g., displays green). In response to detecting that the vehicle has parked in a parking space, the display output is adjusted (e.g., displays red) and the general illumination light source is changed to a different lighting state. Hence, when the user pulls into the parking space, illumination lighting is activated to a brighter setting. The illumination lighting is adjusted to the brighter setting as the user approaches other lighting devices, for example, when approaching an elevator or later re-approaches the vehicle to provide a feeling of safety.
