Abstract

Disclosed are lighting techniques, including systems, apparatus, and methods, that employ optical transmission of two-dimensional control signals to manipulate lighting elements. The lighting apparatus can include a projector with an IR LED array to wirelessly transmit pixel information onto a target space. The pixel information controls lighting elements within the target space. The two-dimensional control signals can includes subareas corresponding to lighting elements in a control array. The lighting elements can be lights of desired wavelengths including infrared and/or visible wavelengths. LEDs can be used as light sources in exemplary embodiments.
