Claim:
1. An illumination device comprising: at least a first light source and at least a second light source, where said first light source and said second light source generate light having different spectral distribution; a number of light collecting means adapted to collect said generated light and to convert said collected light into a number of light beams, said light beams propagate along an optical axis; where said light sources and said light collecting means are displaceable in relation to each other and can be positioned and fixed in a number of mixing positions, where in said number of mixing positions said light collecting means are adapted to collect at least a part of said light emitted by said first light source and at least a part of said light emitted by said second light source, said light collecting means being further adapted to convert said collected light into number of mixed light beams characterized in that at least one of said light sources comprises at least a first emitting area and at least a second emitting area and in that said illumination device further comprises controlling means for controlling said first and said second emitting area independently of each other and in that in at least one first mixing position said light collecting means are adapted to collect at least a part of the light emitted from said first emitting area while substantially not collecting light emitted from said second emitting area of said first light source.
