Abstract: The present invention relates to an illumination device comprising a plurality of light sources emitting light, an optical gate; a light collector arranged between the light sources and optical gate and an optical projecting system adapted to image the optical gate at a distance along the optical axis. The light collector is adapted to collect light from a plurality of light sources and where the light collector comprises a plurality of lenslets collecting light from the light sources and convert the light into a plurality of light beams propagating along an optical axis. Where the axial distances between the lenslets and light sources along the optical axis for adjacent lenslets are different for at least some of the adjacent lenslets.

Abstract: The present invention relates to a light collector adapted to collect light from a plurality of light sources and where the light collector comprises a plurality of lenslets collecting light from the light sources and convert the light into a plurality of light beams propagating along an optical axis. The lenslets are arranged in a dense pattern, where at least 12 outermost adjacent lenslets is located along an outer circular boundary having the same radial distance to a center of the light collector. The dense pattern has been obtained by optimizing a packaging density defined by a ratio of a sum of areas of circular cross sections of the lenslets and an area of the outer circular boundary and that the packaging density is at least 0.79.
