A light outputting apparatus includes a light source that outputs a first light flux, a collimator that parallelizes the first light flux, a light separator that separates the first light flux into a first partial light flux and a second partial light flux, a first light flux width expander, and a second light flux width expander. The light separator causes the first partial light flux to exit in a first direction and the second partial light flux to exit in a second direction. When a first plane is assumed to be a plane containing the first direction and the second direction, the first light flux width expander expands a width of the first partial light flux in a direction along the first plane, and the second light flux width expander expands a width of the second partial light flux in a direction along the first plane.

Control instructions are transmitted to receivers by modulating light sources to generate light beams that are modulated with digital data streams for inducing control instructions in the light beams. Each light beam is applied to a pixel shaper element of a pixel shaper assembly to produce a light pixel, each light pixel carrying the control instructions of the light beam, each light pixel having a perimeter defined by the pixel shaper element. The pixel shaper assembly combines the light pixels into an image without significant overlap or voids between the light pixels emitted by the pixel shaper assembly. The light pixels are directed toward a projector lens for transmission toward the receivers. In a receiver, an optical receiver detects a light pixel. A controller decodes the control instructions received in the detected light pixel and uses the control instructions to control a function of the receiver.
