Patent ID: 8897612

Claim:
A light-coupling optical system, comprising: a transparent sheet having a perimeter; at least one light-diffusing optical fiber having a glass core, a cladding surrounding the glass core, a light-scattering layer surrounding the cladding, and a length, the glass core having randomly arranged voids configured to provide substantially spatially continuous light emission from the glass core and out of the cladding, through the a light-scattering layer and into the transparent sheet along at least a portion of the length, the at least one light-diffusing optical fiber being coupled to at least a portion of the perimeter of the transparent sheet; at least one light source optically coupled to the at least one light-diffusing optical fiber, the at least one light-diffusing optical fiber scattering light optically coupled into the at least one light-diffusing optical fiber from the at least one light source; and a bezel surrounding the at least one light-diffusing optical fiber and the perimeter of the transparent sheet.
