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. Two or more flex strips may be connected together. The flex strips 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: A light source apparatus according to an aspect of the present disclosure includes a first light source that outputs a first luminous flux, a second light source that outputs a second luminous flux, a combiner, a width adjuster that reduces the difference in width between the first luminous flux and the second luminous flux, a first light collection system, a first diffuser, a second light collection system, and a homogenizing system. The first luminous flux traveling via the width adjuster, the combiner, and the first light collection system is collected at a first position, and the second luminous flux traveling via the combiner and the first light collection system is collected at a second position. The width adjuster and the first light collection system approach the aspect ratio and size of a first image formed by the first luminous flux to those of a second image formed by the second luminous flux.

Abstract: A multi-zone illumination system includes a light source formed by first emitters configured to transmit a first light signal having a first polarization state and second emitters configured to transmit a second light signal having a second polarization state transverse to the first polarization state. An optic receives the first light signal and generates a first structured illumination of a first far field zone. The optic further receives the second light signal and generates a second structured illumination of a second far field zone. The first and second far field zones are offset from each other.
