Hollow light conductor luminaire having a modular light extraction device

摘要

The light fitting has a hollow light conductor supplied with light via at least one lamp and coupled to a light output surface via a light coupling device with at least one boundary surface between 2 mediums with different refractive indices having a light refractive structure, for acting as a light screening element, e.g. 2 pairs of overlying prism plates (22,26) fitted to a carrier plate (20). Also included are Independent claims for the following: (a) a lighting system using a number of light fittings; (b) a manufacturing method for a light fitting
