1. Drying light source (1) for illuminating an object with plural high power LEDs, the drying light source comprising:
at least one first individual illumination source (3) comprising at least one high power LED requiring substantial heat dissipation and a second individual light source (3′) comprising at least one high power LED requiring substantial heat dissipation, whereby their emitted light respectively has a dominant wave length (λ1, and/or λ2), and providing a converged beam light beam bundle; and a collector (8), characterized by, optic means (6, 6′, 4, 4′) providing heterodyning of the emitted light and providing homogenization of the converged light beam bundle, the homogenization of the converged light beam bundle realized with a micro lens array comprising a spherical lens or an aspherical lens, the high power LEDs having a spacing to allow separation of the LEDs to reduce a tendency of interference, thereby avoiding overheating. |
