In an escalator (6), passive light sources (2) are mounted at freely selectable illumination points (5), which light sources are each connected by way of a respective optical conductor (4), which is constructed as glass fibre, with an active light source (1) and illuminate the movable stair or pallet belt (14) with the thus received light by way of a respective integrated optical system (1.4). The active light source (1) is easily accessible, centrally arranged and contains a lamp (1.2), the light of which is fed into the discrete optical conductors (4) at the end face in the optical conductor terminal (1.3). These optical conductors together form a fibre-optical light transmission network (3) from the active light source (1) to the passive light sources (2) and are combined at each of both sides of the movable stair belt (14) into a respective strand/shaped optical conductor bundle (2), which bundles are laid into the pedestal channels (23), with branches (24). .The passive light sources (2) need no current supply and also produce no heat and are let into light outlets (25) of the inward balustrade sides (26), the pedestal plates (27), the outer balustrade cover strips (28) or the inner balustrade cover strips (29). This illuminating device serves not only for the illumination, but also for the decorative make-up and makes special light effects possible by the use of coloured or polarised light. By reason of structural advantages, it is particularly suitable for use in the case of narrow profile balustrades and also outdoors, in the case of wetness or moisture.
