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 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: An example of a virtual luminaire store allows a user to select an image or the like for a luminaire appearance and a set of performance parameters related to a virtual luminaire. Based on the user selection, a configuration information file is obtained and transmitted to a software configurable lighting device. The software configurable lighting device receives the transmitted file, stores the transmitted file and generates illumination in accordance with the configuration information from the file.

Abstract: An example of a power and modulation circuit utilizes a very high frequency switching power converter to supply drive current power to cause a solid state light source to emit light. The power converter is configured to convert power from a power source to direct current to supply via the output to the light source, at least in part by a switching function of the power converter at a very high frequency rate. The circuit, in such an example, also includes a control circuit coupled to be responsive to input data and control operation of the power converter so that the current output to drive the light source modulates the light emitted from the light source to also carry the input data.

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: Networked intelligent lighting devices may utilize visual light communication to perform autonomous neighbor discovery, for example, as part of a map generation process. Individually, each intelligent lighting device within an installation transmits a series of packets via visual light communication for receipt by one or more of the other intelligent lighting devices. Receiving intelligent lighting devices record the number of received packets from each transmitter. Records of numbers of received packets are conveyed via a data communication network to a centralized process. The centralized process utilizes the conveyed records to determine neighbor relationships between lighting devices, for example to generate a map of devices as located within the installation.
