ABSTRACT:
A light source device formed of two or more light emitting components and a collector optical component or system which collects light that is emitted from light emitting regions of the light emitting components. Light from the light emitting regions is spatially combined along a common optical axis and formed into an output beam. The light source device positions respective light emitting regions of two or more light emitting components at conjugate foci of a light collector component or system, thus providing a spatially combined output beam from the two or more light emitting regions. Thus, the intensity (i.e., brightness) of the combined output beam exceeds that produced by any individual light emitting region. Further, the light source device of the invention enables a much higher intensity, combined output beam to be produced than previously obtainable from conventional, non-laser light sources.
