ABSTRACT:
Illuminating device with optical conductors for escalators or moving walkways. Passive light sources, in an escalator or moving walkway, are mounted at freely selectable illumination points, with the light sources each being connected via a respective glass fiber optical conductor, with an active light source and serve to illuminate a movable stair or pallet belt with the thus received light via a respective integrated optical system, with the active light source being easily accessible by being centrally arranged and containing a lamp, the light thereof being fed into the discrete optical conductors at the end face in the optical conductor terminal, and these optical conductors together forming a fiber-optical light transmission network from the active light source to the passive light sources and being combined at each of both sides of the movable stair belt into a respective strand-shaped optical conductor bundle with the bundles being laid into the pedestal channels via branches thereof, with passive light sources being received in light outlets of the inward balustrade sides, the pedestal plates, the outer balustrade cover strips or the inner balustrade cover strips.
