Abstract
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.
Claims17
A lighting device, comprising:
- a light source configured to generate light suitable for delivering general illumination of a space;
- a switchable diffuser coupled to receive light output from the light source, the switchable diffuser structured to be switchable between a display mode and an illumination mode;
- one or more switchable polarizers, wherein each of the one or more switchable polarizers is structured to be switchable between a display mode and an illumination mode;
- a liquid crystal filter that is electrically controllable and passes light generated by the light source;
- and
- a controller, coupled to the light source, the switchable diffuser, the one or more switchable polarizers and the liquid crystal filter, to control operation of the light source, the switchable diffuser, the one or more switchable polarizers and the liquid crystal filter.
3 more elements
A device, comprising:
- a light source;
- a display;
- and
- a controller, coupled to the light source and the display, the controller configured to:
- in an illumination mode, operate the device to output light from the light source to provide general illumination to a premises;
- and
- in a display mode, operate the device to output an image via the display.
4 more elements
A display device, comprising:
- a light source configured to generate light for output from the display device;
- and
- one or more controllable light processing components coupled to the light source for processing the output light according to a display device mode, the light source and the one or more controllable light processing components configured to:
- in a first mode, output general illumination lighting over the entire output surface of the display device;
- and
- in a second mode, generate a display of an image over an entire output surface of the display device.
3 more elements
An apparatus, comprising:
- a controllable source of light;
- a controllable display device;
- and
- means for selectively operating the apparatus at different times in different first and second modes, the first mode including outputting light from the light source to provide general illumination to a premises, and the second mode including operating the display device to output an image.
