Beschreibung
Zusammenfassung:The invention provides a lighting system (100) comprising: -a plurality of n light sources (10), wherein each of the n light sources (10) is configured to generate light source light (11); -a plurality of n first beam shaping elements (20), wherein each of the n first beam shaping elements (20) is configured downstream of a respective light source (10); -k arrays (300) of optical elements (310), wherein each of the k arrays (300) comprises nk optical elements (310), wherein each of the nk optical elements (310) is configured downstream of a respective first beam shaping element (20) from a subset (250) of the n first beam shaping elements (20); wherein the optical elements (310) are configured to influence one or more of (i) a beam direction of the light source light (11), (ii) a beam shape of the light source light (11), (iii) a spectral distribution of the light source light (11), and (iv) an intensity of the light source light (11); and wherein n≥2, k≥1, and 1≤nk≤n.
