Abstract
A planar light source apparatus includes a number of lighting elements disposed in a common plane, and a number of mirror reflectors arranged perpendicular to the common plane and facing the lighting elements. The mirror reflectors each have a reflecting surface facing the lighting elements. The light elements are arranged in a lattice such that the distance from one of the reflectors to the nearest lighting element is a maximum of the half the distance between two adjacent lighting elements.
