1. An illumination device comprising:

  • a first light source array comprising at least a first light source;

    said first light source generates a first light beam having a first spectral distribution;

    said first light beam propagates primarily in a first direction along an optical axis;

    a second light source array comprising at least a second light source, said second light source generates a second light beam having a second spectral distribution;

    at least one first dichroic reflector positioned at least partially in said first light beam and said second light beam;

    said first dichroic reflector transmits at least a part of said first light beam and reflects at least a part of said second light beam;

    whereinthat said second light beam propagates primarily in a second direction along said optical axis substantially opposite said first direction and towards at least a part of said first light source array;

    that at least a part of said second light beam propagates primarily in said first direction after being reflected by said at least one first dichroic reflector.
