Claim:
An illumination system comprising: a linear array of light emitters (R, G, B, A, W) associated with at least one linear array of outcoupling means (O 1 , O 2 , O 3 , . . . ) for coupling light emitted by the light emitters (R, G, B, A, W) out of the illumination system, each linear array of outcoupling means (O 1 , O 2 , O 3 , . . . ) being arranged parallel to the linear array of light emitters (R, G, B, A, W), for each linear array of outcoupling means (O 1 , O 2 , O 3 , . . . ), a configuration of the outcoupling means (O 1 , O 2 , O 3 , . . . ) and a configuration of the light emitters (R, G, B, A, W) fulfilling the requirement: N CU ×N LC =N OU ×N LO , wherein N CU is a number of clusters (C 1 , C 2 , C 3 , . . . ) per unit (U 1 , . . . ), N LC is a number of light emitters (R, G, B, A, W) in each of the clusters (C 1 , C 2 , C 3 , . . . ), N OU is a number of outcoupling means (O 1 , O 2 , O 3 , . . . ) per unit (U 1 , . . . ), N LO is a number of light emitters per outcoupling means (O 1 , O 2 , O 3 , . . . ), wherein a “cluster” (C 1 , C 2 , C 3 , . . . ) is a smallest repetitive collection of light emitters (R, G, B, A, W) forming the linear array of light emitters (R, G, B, A, W), each cluster (C 1 , C 2 , C 3 , . . . ) comprises a plurality of light emitters (R, G, B, A, W) of at least a first primary color and a second primary color, the second primary color being distinct from the first primary color, and a “unit” (U 1 , . . . ) is a smallest number of adjacent clusters repetitive with respect to the outcoupling means (O 1 , O 2 , O 3 , . . . ) in the at least one linear array of outcoupling means (O 1 , O 2 , O 3 , . . . ) and with respect to the light emitters (R, G, B, A, W).
