Luminaire, has optical device that deflects part of light of principal guide, and guide part whose two light inputting transparent walls increase section of guide from upstream point to downstream point

摘要

The luminaire has a principal guide part that passes light according to a right trajectory or a curve of an upstream point to a downstream point by reflections on side walls of the guide part. An optical device i.e. deflector (113), deflects a part of the light of the guide part. Two light inputting transparent walls (121) of the guide part increase a section of the guide part from the upstream point to the downstream point. The optical device is provided with a convergent optical device i.e. condenser (115), that modifies a solid angle of a light beam of the optical device.
