Luminous wall, has concentrator deviating light beam by converging light beam, and transmission zone to which part of light beam is directed towards light inlet zone of adjacent elementary optical device

摘要

The wall has an elementary optical device (11) including a side zone (112) i.e. inlet zone of light. A diffuser (113) deviates a light beam by diverging a light beam. A concentrator (115) deviates the light beam by converging the light beam. A part of the light beam entering to the elementary optical device by the light inlet zone is deviated by the diffuser towards the concentrator, where remaining part of the light beam is directed towards a transmission zone (114) towards a light inlet zone (122) of an adjacent elementary optical device (12).
