A light system comprising controllable light sources (35) positioned along alternative routes of movement to serve as optical means for influencing persons to follow an indicated route of movement to one selected of a plurality of target areas, the system having control means (1, 2) for turning light sources on and off to generate along the route indicated a moving light effect travelling in the direction of the target area selected. At least one display unit (13) is provided for presenting a general view of alternative routes of movement along which the light sources are located. In response to an assignment command entered through input means (11) included in the system, processing and communication means (12, 14, 21, 22) activate the travelling light along each route assigned. In the system, a modular light-rail (3) adapted for directing persons by means of said travelling light effect in one selected of two opposite directions along the rail, is provided with low power light sources (35, 36), preferably of the type having light emitting diodes, disposed as to illuminate a reflecting field. |
