Abstract: A spatial light system that may, for example, be used to project image content onto surfaces of a room. The system may include two or more projection units for emitting light onto surfaces within a room. The system may include a controller and two or more projection units, each module including an LED array, an array of light pipes, and a condenser lens. Two or more projection units may be connected to a flexible strip that provides power and data (e.g., serial data) to the projection units, a composable light emitter unit, or a bulb-form projection system. Two or more flex strips or composable light emitter units may be connected together to provide a serially-connected, flexible modular architecture for spatial light systems that allow the projection units to be conformed to a variety of configurations and shapes.

Abstract: An electronic device may have a surface area that may or may not overlap a touch sensor and that may be illuminated. The surface area may have an appearance that matches adjacent housing surfaces when not illuminated from within the device. When it is desired to create notifications or reconfigurable touch controls, a pixel array under the surface area may be used to produce patterned illumination. A louver layer may be interposed between the pixel array and the surface area. The louver layer may have louvers that are tilted with respect to a surface normal associated with the surface area. The louver layer may have cores and claddings that are formed from materials that help impart a non-black appearance to the surface area when corresponding portions of the underlying pixel array are inactive and not emitting light.
