Definitions

  • the invention relates to an escalator or moving walk, according to the preamble of claim 1.
  • LEDs along an escalator or a moving walk has long been known.
  • DE-GM 296 08 741 shows the arrangement of LEDs in recessed form for passenger transport devices such as escalators.
  • light-emitting diodes can also be realized in a channel along the balustrade of the escalator, for which purpose reference is made, for example, to DE-GM 200 19 698.
  • Such channels have the beneficial effect that the light emitting diodes are quite well protected even against influences such as pollution and damage, especially when a smooth and easily wipeable cover, which is also carried out reasonably stable, is used. Also can be quite well controlled by the recessed arrangement of the light emitting diodes - especially when using reflectors - so that it is possible, for example, to illuminate the tread plate or the pallet band or the step band to a certain extent.
  • Such light emitting diode bands usually consist of a plurality of juxtaposed LEDs. Escalators and moving walks may well have a length of 10 meters or, for example, even 30 meters.
  • light-emitting diodes themselves are comparatively small, with the typical diameter of the chip which effects the light output being, for example, 0.5 mm and the light-emitting diode being cast in a housing made of transparent plastic, which for example has a diameter of 3 or 5 mm.
  • the light-emitting diode band would be formed by light-emitting diodes arranged directly adjacent to one another, that is, adjacent to one another.
  • the light-emitting diodes are therefore arranged at a distance of, for example, 2 to 5 cm.
  • the light-emitting diodes produced in recent times are comparatively much brighter and emit a greater luminous flux than light-emitting diodes such as those produced, for example, 10 years ago. Therefore, it is more cost effective if, for the provision of the desired illumination, the distance of the light emitting diodes is further increased, for example, to 5 to 8 cm or even beyond.
  • balustrade base is preferably quite compact and has a fairly small lateral width, in which then also fasteners of the escalator or the moving walk for the steps, the lateral adjustment storage for the balustrade pedestal and possibly other components of the escalator or the moving walk must be included so that the place is extremely cramped there.
  • the invention has for its object to provide an escalator or a moving walk according to the preamble of claim 1, which allows the illumination through a light strip not only for solid balustrades but also in Balustradensockeln with aesthetically pleasing design.
  • the homogenization effect can be achieved particularly favorably by the light diffuser, which is arranged between the cover and the light-emitting diode, due to the special countersinking of the preferably rectangular channel.
  • the required depth to provide the continuous light output drops drastically by the provision of the light diffuser, with a distance of 20 mm in front of the light emitting diode being sufficient for equalization.
  • One construction depth of the channel of, for example, 100 mm according to the invention is readily avoidable, so that surprisingly the solution according to the invention can also be accommodated in a balustrade pedestal, where it can illuminate the edge of the step conveyor in a targeted and directly spaced manner from the step conveyor, if desired.
  • a so-called Frenell lens is incorporated in the cover, which serves to focus. If necessary, the focal point of the Frenell lens can easily be displaced towards the step or pallet strip, so that the light output, for example, can emerge from the cover at an angle of approximately 45 °.
  • the cover is provided to form the cover as an optical component.
  • it may be slightly convex, for example, viewed in the direction of a section, so that it serves to focus the emitted light radiation.
  • the light diffuser can also be formed as an optical component, that is, for example, instead of a transparent or translucent disc having a convex or even a concave shape.
  • Any light-deflecting and scattering element suitable for this purpose is suitable as a light diffuser.
  • a so-called black glass pane can be used, which is permeable to the light wavelength of the light-emitting diodes and has soot particles.
  • any suitable material may be used, for example, polyacrylic. It is also possible to form the light diffuser as a disc which is etched or otherwise frosted on one or both sides. By arranging the light diffuser, the light emitted by the light emitting diodes can be distributed, and surprisingly results the double arrangement of cover and light diffuser a strong homogenization with high light output, so that it is erfindungsgzeß also possible to use a small number of very bright light emitting diodes distributed over the length of the escalator.
  • a longitudinal spacing of the light-emitting diodes of 10 or even 12 cm can be selected without the undesired "candlestick effect" occurring. This effect can be achieved if the cover itself is additionally matted and - for example on its inside - has an etched surface.
  • a light-emitting diode channel according to the invention designed in this way results in a lower production cost.
  • the individual light-emitting diode is more expensive than a light-emitting diode with a lower light output.
  • the installation costs are significantly lower, so that the total costs can also be significantly reduced.
  • escalator 10 is shown in a small detail, which is essential to the invention.
  • a balustrade base 14 is provided which carries and receives the channel 16 according to the invention with the multiple arrangement or series arrangement of light-emitting diodes or LEDs 18.
  • the channel is designed at a certain depth, namely in the illustrated embodiment with a depth of more than 40 mm between the light-emitting diodes 18 and a light diffuser 20, which is arranged adjacent to a cover 22.
  • the cover 22 is made of transparent and viscoplastic.
  • transparent does not mean a light transmittance with a light absorption in the per thousand range, but a light absorption of less than, for example, 20%.
  • the cover 22 extends with its front side 24 flush with the balustrade pedestal 14.
  • the balustrade pedestal 14 has a vertically extending leg 26 and an obliquely upwardly extending leg 28, as is known in the art.
  • the balustrade glass adjoins with its storage at the upper / recessed end of the oblique leg 28 at.
  • the light diffuser 20 is formed as a frosted glass. It extends just behind the cover 22, wherein a light width of, for example, 8 mm, 10 mm or 12 mm is provided between these two penetrated by the light radiation optical elements.
  • the cover 22 has in the illustrated embodiment, a flat front surface and a slightly curved back 30. This makes it possible to provide a light condensing lens effect for focusing the light.
  • the channel 16 is provided with a projecting flange 32 and a recessed flange 34. Both flanges extend away from the channel, ie upwards or downwards.
  • the channel 16 is fixed to the flange 32 on the bottom of the sheet metal of the Balustradensockels 14, and above with the flange 34 behind the plate of the balustrade pedestal 14. With this configuration can ensure that from the sloping leg 38 run-down water - as through Precipitation is provided - does not penetrate into the channel 16.
  • the channel 16 is mounted in a conventional manner in the balustrade base 14.
  • the channel 16 is a prefabricated plastic molded part, which can be realized as an extruded profile used.
  • the channel 16 has inwardly facing latching projections 60 and 62.
  • the latching projections 60 and 62 are used to accommodate fluorescent tubes, so that in the inventive solution, a replacement of existing fluorescent tubes by a much longer life-facing light emitting diodes 18 is possible.
  • the fluorescent tube together with its holder must thereby be removed, and the light-emitting diode row 18 and the light diffuser 20 are used, so that no additional costs arise in this respect, whereas the maintenance costs are significantly reduced.
  • the light emitting diode row 18 is constructed from each individually spaced at a distance of Beipsielêt 10 cm, bright light emitting diodes. It is understood that instead of a realization via appropriately preassembled LEDs - for example, on a printed circuit - can be realized.
  • the light diffuser 20 is located inside latching projections 60 and 62, which are provided for the attachment of the cover 22 and enter corresponding grooves in the channel 16. As a result, an inwardly pointing shoulder is formed, and the light diffuser 20 may be used here, it being understood that it is preferably additionally attached at least at the ends.
  • FIG. 2 A modified embodiment of a light diffuser is shown in FIG. 2.
  • the channel 16 is prefabricated separately, so that no locking projections 60 and 62 are provided.
  • the light diffuser 20 is directly adjacent to the LEDs 18, and there is a correspondingly large distance of, for example, 50 mm between the light diffuser 20 and the back of the cover 22.
  • the channel 16 used for illumination purposes is arranged directly adjacent to the step band 12, that is to say in the balustrade base. It is understood, however, that it is also readily possible, for example in the case of a fixed balustrade, to arrange the balustrade pedestal a little higher so that, apart from the illumination purposes, it can also be used for illumination purposes, emitting a uniform light.
  • the light diffuser 20 by a special embodiment of Cover 22 to replace.
  • the cover 22 is blasted in this embodiment so that it acts highly diffusible for light.
