Lighting system for tunnel in building, has optical light guide linked to light guide light extraction unit, and two light sources inserted into translucent body, where light guide is included in container body

摘要

The system has an optical light guide (6) linked to a light guide light extraction unit, where the light guide is included in a container body. Two light sources i.e. LEDs, are inserted into a translucent body, and a recess (3) is formed along an outer surface of the container body, where the translucent body is made of polyurethane. The recess extends along the length of a profile of a holder body, which comprises fiber reinforced plastic, where the light guide and the translucent body have an optical reflectivity of 80 percentages. An independent claim is also included for a device for making a recess in a light guide and a translucent body.
