Claim:
1. An illumination device comprising: a viscoelastic lightguide comprising at least one pressure sensitive adhesive (PSA) so that the PSA is within the viscoelastic lightguide and the viscoelastic lightguide is configured to transport light within the viscoelastic lightguide by total internal reflection, wherein the viscoelastic lightguide defines opposing first and second major surfaces; and a flexible light mat comprising a plurality of electrically interconnected light emitting diodes disposed on a flexible mat, the light emitting diodes optically coupled to the viscoelastic lightguide, wherein light emitted by the light emitting diodes enters the viscoelastic lightguide at the first major surface and is transported within the viscoelastic lightguide by total internal reflection.
