Title
(EN) MICRO LED SHEET WITH SMALL SPHERES TO ENABLE DIGITAL BEAM SHAPING
(FR) FEUILLE À MICRO-DEL COMPRENANT DES PETITES SPHÈRES PERMETTANT UNE MISE EN FORME DE FAISCEAU NUMÉRIQUE
Abstract
(EN)
The invention provides a lighting device (1100) comprising a first 2D arrangement (100) of a plurality n of light sources (10) and a second 2D arrangement (200) of a plurality m of beam shaping elements (20) configured downstream of the light sources (10), wherein: - the light sources (10) are configured to generate light source light (11), wherein the n light sources (10) comprises a plurality k of individually controllable subsets (110) of light sources (10), wherein the beam shaping elements (20) are configured to shape a beam of the light source light (11) of the n light sources (10), and wherein n≥16, m≥4, n/m>1, and 4≤k≤n; - upstream of each beam shaping element (20) light sources (10) are configured of different individually controllable subsets (110), and wherein two or more of the beam shaping elements (20) have different spatial configurations of the light sources (10) that are configured upstream of the respective beam shaping elements (20).
