LIGHT SOURCE APPARATUS AND METHOD FOR GENERATING A MIXED COLOR LIGHT BEAM

摘要

The present application discloses a light source apparatus, which includes a first, second and third light source each configured to generate a different color light beam; a beam combining element having a first incident surface directed to the first light source, a second incident surface directed to the second light source, a third incident surface directed to the third light source and an emergent surface; and a first lenslet array placed on the first incident surface, a second lenslet array placed on the second incident surface and a third lenslet array placed on the third incident surface of the beam combining element, wherein the beam combining element is configured to combine the light beams from the first, second and third light sources into a mixed-color light beam and to emit the mixed-color light beam from the emergent surface.
