Abstract
A light shaping assembly comprises a printed circuit board (PCB), a two-dimensional (2D) array formed of a plurality of rows, each row comprising a plurality of light sources mounted on the PCB, and a Fresnel lens. The Fresnel lens redirects a light beam emitted by each light source at an angle that increases as a function of a distance between each light source and a selected point on the PCB, so that the light beams emitted by the light sources are collectively directed toward a common target.
