1. A light generating system comprising an array of n light generating devices, wherein n≥20, and a control system configured to control the light generating devices, wherein:
the array of n light generating devices comprises m first light generating devices and k second light generating devices; wherein the second light generating devices are disposed in an at least partly random arrangement within the array of plurality of light generating devices; wherein m≥10; k≥3; and 2≤m/k≤5; wherein the first light generating devices are configured to generate first device light and wherein the second light generating devices are configured to generate second device light;
in an operational mode:
the control system is configured to control g1 first groups of the first light generating devices, wherein 1≤g1<b, wherein b=g2, wherein each first group of the first light generating devices comprises g11 first light generating devices, wherein g11 for each first group is individually selected from the range of b≤g11≤m, and wherein the sum of all g11's is m;
the control system is configured to individually control g2 second groups of the second light generating devices, wherein 2≤g2≤k, wherein each second group of the second light generating devices comprises g22 second light generating devices, wherein g22 for each second group is individually selected from the range of 1≤g22≤k−1, and wherein the sum of all g22's is k;
a lighting parameter of the second device light of respective second groups of second light generating devices of q2 second groups of the second light generating devices changes mutually non-synchronically with time, wherein 2≤q2≤k.
