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.

Systems and methods to provide configuration data to a software configurable lighting device

For a luminaire offering both illumination and display functionality, control strategies coordinate illumination/image output so as to mitigate interference of the illumination light output with aspects of the displayed image light output. In one example, when displaying a selected image with one or more white regions in the image, a sufficient number of selected white illumination emitters can be ON or operating in a low power state in the white regions while the rest of the luminaire output area can display the non-white elements of the image with aligned illumination emitters turned OFF. In another example, an image is displayed in a selected region of the luminaire output while illumination emitters within the area displaying the image are OFF or operating in a low power state, but illumination emitters along other parts of the luminaire output are turned ON.

Illumination and display control strategies, to mitigate interference of illumination light output with displayed image light output

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.

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.

Software configurable lighting device

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.

Luminaire and lighting system, combining transparent lighting device and display coupled to output image via the transparent lighting device

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.

Auto-discovery of neighbor relationships and lighting installation self-mapping via visual light communication

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.

The examples relate to various implementations of a software configurable lighting device, having an enhance display device that is able to generate light sufficient to provide general illumination of a space in which the lighting device is installed and provide an image display. The general illumination is provided by additional light sources and/or improved display components of the enhanced display device.

Enhancements of a transparent display to form a software configurable luminaire

Disclosed herein is a lighting device including a luminaire having a first light emitter configured to output image and a second light emitter configured to output illumination light. The first light emitter is oriented with the second light emitter such that an available output region of the second light emitter at least substantially overlaps an available output region of the first light emitter. The lighting device also includes a processing system coupled to a driver system, which is coupled to the luminaire. The processing system, via the driver system, is configured to operate the first light emitter to output the image and operate the second light emitter to output the illumination light; and during the operations of the first and light emitters to output a combined light via the substantial overlap, to control the output of at least one of the image or the illumination light to control flicker due to interaction of a portion of the image and a portion of the illumination light.

Controlling flicker caused by multiple light sources

The examples relate to various implementations of a software configurable lighting device having a multi-processor system including a central processing unit and a parallel processing unit. The software configurable lighting device utilizes the multi-processor system to efficiently transform and/or modify control data. The software configurable lighting device also includes a transparent image display device and a general illumination device. Transformed and/or modified control data is utilized to drive the transparent image display device and the general illumination device in combination.

Multi-processor system and operations to drive display and lighting functions of a software configurable luminaire

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.
