ABSTRACT:
With this illumination device for the illumination of a transport system, such as escalators and passenger walkways, light sources are provided in the balustrade skirting. The light of the light source is reflected by lenses upon intermediate legs of a support device which carries the handrail of the transport system. By ascribing a suitable configuration and surface properties to the intermediate legs the light is deflected in a desired direction. This illumination device serves not only for illumination purposes but also for the decorative or aesthetic appearance of escalators and passenger walkways.
