Escalator or moving walkway balustrade illumination

摘要

The glass balustrade of an escalator or moving walkway passenger conveyor is provided with an internally illuminated rail on its side surface. The rail is illuminated by a light beam which is piped up through the interior of the balustrade panels from a light source disposed beneath the outer deck of the passenger conveyor. The light source includes a neon emitter disposed at the focal point of a parabolic mirror so as to provide a parallel band of light which is projected into a lens set. One lens narrows the band of light and the second lens produces a collimated beam from the narrowed light band. The collimated light beam is projected into the bottom of the balustrade panels. The light beam is then serially reflected up through the glass panels to the illuminated rail. The stripe is a semi-circular rod of glass which is glued onto the side of the balustrade, and is formed from a glass having substantially the same index of refraction as the balustrade panel glass.
