ABSTRACT:
Solid-state area illumination stems and method for forming such systems are provided. The illumination system comprises: a plurality of OLED devices each device formed on a separate substrate and each device emitting light at a plurality of angles relative to the substrate, the emitted light having different ranges of frequencies at different ranges of the plurality of angles; and a support positioning each of the plurality of OLED devices at a plurality of orientations relative to an area of illumination, the positioning being defined so that any point on any surface within the area of illumination will receive a broadband combination of light from more than one of the OLED devices.
