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.

According to the present disclosure, an illumination apparatus includes a pump radiation source for emitting pump radiation, a phosphor element for converting the pump radiation into conversion light and a carrier, on which the phosphor element is mounted, which carrier is made of a carrier material which is transparent at least for the pump radiation and has a refractive index n.sub.carrier. The pump radiation passes through the carrier, exits at an exit surface of the carrier and is then incident on a pump radiation input coupling surface of the phosphor element that is arranged at the exit surface. The pump radiation in the carrier is incident on the exit surface of the carrier with a centroid direction, which centroid direction is inclined with respect to a surface normal on the exit surface by an exit angle .sub.out0, and .sub.out<.sub.c with .sub.c=arcsin(1/n.sub.carrier).
