1. A solid-state area illumination light source, comprising:

  • a) a planar substrate,b) a non-pixellated organic light emitting diode (OLED) layer deposited on the planar substrate, the organic light emitting diode layer including first and second electrodes for providing electrical power to the OLED layer,c) an encapsulating cover covering the OLED layer;

    d) first and second conductors electrically connected to the first and second electrodes, and extending beyond the encapsulating cover for making electrical contact to the first and second electrodes by an external power source; and

    e) a lenslet array located on the encapsulating cover and coextensive with the OLED layer for directing the light emitted by the OLED layer, wherein the encapsulating cover is transparent, and light is emitted from the OLED layer through the encapsulating cover.
