Abstract
An illumination system includes at least first and second laser illumination sources. A down converter material emits light when illuminated by one or more of the laser illumination sources. The first laser illumination source is arranged to illuminate only a first portion of the down converter material. The second laser illumination source is arranged to illuminate only a second portion of the down converter material. Control circuitry causes the first laser illumination source to adaptively vary a first intensity of illuminating the first portion of the down converter material, causes the second laser illumination source to adaptively vary a second intensity of illuminating the second portion of the down converter material, and causes the light modulator to allow a selected amount of the down converter material's emitted light to be projected from the system.
