Abstract

A flexible light guide that has a homogeneous light emission with high luminance is provided. The flexible light guide is provided by a side-emitting light guide. The side-emitting light guide includes a light-guiding fiber designed as a side-emitting fiber so that light guided in the fiber is scattered out along a longitudinal direction in a distributed manner. The guide also includes a tube that surrounds the fiber. The tube is designed to be light-scattering and translucent so that light emitted from the fiber can traverse the tube with scattering. The tube is surrounded by a cladding. The tube and cladding are made of plastic.
