1. An illumination device comprising:
a number of light sources arranged in at least a first group of light sources and a second group of light sources, wherein said first group of light sources and said second group of light sources are individually controllable; a number of light collectors collecting light from said first group of light sources and converting said collected light into a number of source light beams; and at least one light guide comprising an input section and an output section, said light guide receiving light generated by said second group of light sources at said input section and transferring said received light to said output section, said output section comprising an area completely surrounding at least one of the said light collectors and being adapted to emit said received light at the area, wherein said light guide is formed as a light guide disc comprising a number of openings wherein said light collectors are arranged, and wherein a front area of the light guide disc comprises said output section and said output section is adapted to diffuse said emitted light into many directions.
