An adjustable beam lighting solution is coming widely on demand for different applications with improved energy efficiency, reduced light pollution, or enriched decorative effects. A Matrix Lighting configuration, which mainly consists of a light-emitting diode matrix and a lens array, is proposed as a promising adjustable beam lighting solution. It easily builds up the source-target mapping based on the integral imaging principle, and it could adjust the light beam and shape freely and timely. The basic configuration, the general design rules with imaging optics, and the optimization approaches based on ray tracing were presented. An example lighting system consists of a 32 × 32 × RGB lightemitting diode matrix, and the 8 × 8 Fresnel lens array is demonstrated, which accomplishes a localized lighting with addressable regions for power saving. It can also project colorful patterns on the ground or a wall for atmosphere heightening.
