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.

An arrangement of adjacently disposed lighting unit structures in which in each structure a member comprising part of a lighting element rigidly interconnects spaced end walls, the lighting element including a fluorescent lighting lamp or lamps which are supported by the member. Each end wall includes an inner wall portion together with side flange portions which project outwardly from the inner wall portion, the side flange portions of each end wall having outer edges which are secured in an airtight manner to the outer edges of the side flange portions of the adjacent end wall of the adjacently disposed, lighting unit structure. An air chamber is thus provided between these adjacent end walls, a ventilation air inlet to the air chamber being provided, and the inner wall portion of each end wall having a lower edge which is so disposed inwardly of the outer edges of the side flange portions of the end wall that a ventilation air outlet is thereby provided between the lower edge and the lower edge of the inner wall portion of the adjacent end wall of the adjacently disposed lighting unit structure.

A mounting device for supporting a decorative string of the type including a conducting cord, a plurality of bulb sockets connected in series by the conducting cord and a plurality of bulbs respectively mounted in the bulb sockets, the mounting device including two symmetrical cover shells covered on and fixedly fastened to each other to hold the bulb sockets, the conducting cord and the bulbs on the inside, two mounting tubes at one side, and two anchoring devices detachably connected to the mounting tubes for fastening to the ground, the cover shells having each sets of locating rods symmetrically disposed at two opposite sides and respectively clamped on the periphery of the bulb sockets at two sides to hold down the bulb sockets in position, and a plurality of through holes through which light from the bulbs pass to the outside.
摘要:
A light guidance system for the illumination of an interior area with a light deflection device which reflects daylight coming from outside of the interior area as well as artificial light coming from inside of the interior area. The light deflection device comprises several elements disposed parallel to one another and spaced apart from one another such that light from outside of the interior area can penetrate through the space into the interior area, and each of said several elements has at least one reflector surface and is impervious to light.
摘要:
A decorative drop ceiling including a panel having a plurality of openings therein disposed between a source of light and an area to be illuminated. A light transmissive lens is disposed in each of the openings. Each lens has a predetermined thickness dimension, which is not dictated by the thickness of the panel. The lower face of each lens is co-planar with the lower surface of the panel. The periphery of the lens is recessed, and fasteners, disposed in the recess, fix the lens in the opening.

As a part of a ventilating or air conditioning system a plurality of parallel hollow carrier sections are arranged in spaced relation under a ceiling slab. Said hollow carrier sections are provided with upper and lower support means facing towards the space between said carrier sections. At least some of said upper means support carrier plates provided with lighting fixtures on the underside thereof. At least some of said lower means support transparent or translucent optical panels provided under and spaced from said carrier plates. Other of said lower means support acoustic panels, cover plates or the like. Air flow connection from the underlying room to the space between the carrier plates and the optical panels is ensured. The walls of the parallel hollow sections are provided with apertures being in air flow connection with the spaces between the carrier plates and the optical plates to cause the air flow from the underlying room when the ventilating system is in operation to ventilate the lighting fixtures on its way to the interior of the hollow section. The air flow stream may be reversed.

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.
