Abstract

The guide comprises one or more concentric layers of intertwined cable based on optical fibre guides for controlling the transverse losses of light to achieve homogeneous illumination along the guide, the individual guides consisting of polymethylmethacrylate with fluoropolymer sheath.

Claims

1. Optical fibre light guide, characterised in that it comprises one or more concentric layers of intertwined cable comprising optical fibre guides for controlling the transverse losses of light to achieve homogeneous illumination along the guide.

2. Optical fibre light guide according to claim 1, characterised by the arrangement of a solid core in the interior of a successive layer of intertwined guides with reflective and contrasting properties.

3. Optical fibre light guide according to claim 1, characterised in that the individual guides are made of polymethylmethacrylate with fluoropolymer sheath.
