Abstract
The illumination system has an array of light sources (', . . . ) such as an array of light emitting diodes arranged in a pre-determined manner in a first plane (), wherein dis a characteristic dimension of the spatial arrangement of the light sources in the first plane. An array of associated lenses (′, . . . ) is arranged in substantially the same pre-determined manner in a second plane (). Each lens has substantially the same focal distance f. The array of lenses is provided at a plane distance dfrom the array of light sources. The plane distance dis substantially equal to the focal distance fof the lenses. The illumination system has displacement means for displacing the array of lenses with respect to the array of light sources so as to obtain a plurality of directional light beams projecting spots on a projection plane arranged at a projection distance dfrom the illumination system, wherein d≧10×dand d≧10×d.
