State of the art

Lighting installations of the aforementioned type and methods for replacing at least one luminous element of such a lighting installation are well known. The front elements can, for example, glass, natural stone, especially alabaster or onyx or a metal fabric or knitted or knitted fabric or fleece with translucent meshes or open spaces, however, do not allow direct eye contact, or in particular from Lichtleitbeton or gypsum or -lehm in whose matrix material (concrete, gypsum, loam) a variety of photoconductive fibers (polymer- or silicate-based) are embedded.

The known installations are typically backlit

Façades, which can be generated by the backlight special aesthetic effects or even characters, symbols or images on the front panel.

Usually, in the case of the failure of a luminous element, which is usually formed by an LED in each case, access from the external environment to the intermediate space must be created by removing a front element. An access from the side of the rear wall or ceiling or a side access in the space and a

Movement of a person within the space is mostly constructed,

especially for reasons of space, not possible. The disadvantage is in the known

Lighting installations or the method for the exchange of light-emitting elements while the fact that depending on the position of the defective light element, which is typically noticeable in an incomplete optics in the active state of the light elements, different numbers of mostly existing in large numbers plate-shaped Fro telemente be removed got to. Thus, not infrequently due to the mounting of the front elements a certain assembly and disassembly order to comply with the front elements, so that it may be necessary to successively expand an entire vertical row of front elements from the top front element of the series starting to the bottom successively to a defective To replace lighting element behind the lowest front element of said row. A reassembly of the front elements is done after replacing the light element then in reverse order.

From DE 20 2012 000 083 U1 an LED lighting unit with easy to changing light source is known. The LED display described consists of a light guide plate and a bar, with the aid of a light entrance side of the light guide plate is illuminated. there the LEDs together with a carrier profile, at least one end piece and a terminal box together form a so-called light unit. This light unit is inserted into a side opening of the LED display and can be removed in this way again from the LED display. The previously known LED display has only as a carrier body to be picked up and provided with LEDs bar and is also not suitable to be equipped with a plurality of such strips, which could be inserted through the same lateral opening of the display.

DE 698 35 079 T2 describes a lighting arrangement for use in a nuclear power plant, wherein a lighting means by means of an articulated movement means by a serpentine extending channel is displaceable. Characteristic of this previously known illumination device is the non-linear course of the channel, which has reasons for a better radiation absorption in the region of the wall penetrated by the channel. The use of a plurality of light elements in conjunction with the one channel is neither provided nor useful in the known lighting device, since a series arrangement of the light elements in the longitudinal direction of the channel would cause no light could be emitted from the rear light elements, since the material of penetrated by the channel wall is impermeable to light.

task

The invention has for its object to further develop a lighting installation of the type mentioned or a method for replacing at least one light-emitting element of such a lighting installation such that the replacement of a defective lighting element can go much easier.

solution

Starting from a lighting installation, as described above, this object is achieved by a movement device with which the

Illuminating elements (8), preferably successively, are movable towards the access (27) and then into the external environment or through the access (27) into the external environment, as well as an articulated and / or detachable connection between adjacent ones

Luminous elements (8).

The invention thus makes use of the basic principle not to provide access where there is a generally exchangeable lighting element, but at least one "fixed", ie determined from the outset, access to which then the lighting elements are movable Such, preferably single access, can already be provided during the planning of the lighting installation and accordingly good and relatively easy to be included in the overall design of the installation. The subsequent creation of an access is then no longer necessary. The planned and established access in the lighting installation according to the invention should be arranged so that it is easily accessible and easily, if necessary, first produced and later resealable and high demands on the

Architecture or aesthetics is enough.

The lighting installation according to the invention typically has a plurality of luminous elements which, in their operating position in which they are located in the intermediate space between the front element and the rear wall, have a (large) areal shape. If such a plurality of light-emitting elements as a whole are rigid or not detachable from one another, then the entirety of the light-emitting elements could be removed in a direction perpendicular to the front element only through such an access, which

Dimensions approximately as the majority of the lighting elements (viewed in directions parallel to the front elements) has. Such access would thus be the

Dimensions of the front element correspond, which is unacceptable for aesthetic and technical reasons. For this reason, the principle according to the invention of the active combination of exchangeable luminous element and the access through which such replacement can take place is particularly advantageous and also preferable to an alternative variant in which the access would be variable in position, whereas the luminous elements are immovable would.

In principle, there are two possibilities for using a fixed access with regard to its position:

Either work from the outside through the access and the replacement of a respective lighting element takes place in the space in one

sufficiently small distance from the external environment of the lighting installation, so that the light-emitting element to be exchanged is accessible from an outer boundary plane of the front elements with the hands, so that the distance between the access, which can be defined as access cross-section, and a mounting location of the exchanged light element maximum should correspond to the arm length of a human.

The second alternative of exchange may be that the one in question

Luminous element is moved by means of the movement device through the access into the external environment and there, that is adequately removed from the lighting installation itself, is replaced. Preferably, the movement device is designed in such a way that that a plurality of luminous elements, preferably in common, from the

Gap out and are movable into the external environment.

In an articulated connection of the luminous elements or of support elements on which the luminous elements are arranged, it is particularly advantageous if an axis about which adjacent luminous elements or support elements are pivotable relative to each other, runs parallel to the back plane of the front element or front plane of the rear wall or ceiling , In the case of a detachable connection of individual lighting elements or support elements, the plurality of lighting elements or support elements in the operating state can also be rigidly coupled to each other, since within the space a linear movement of the totality of the lighting elements or support elements parallel to the backplane of

Front element towards the access is possible, provided that successively more lighting elements or support elements are removed by peeling from the composite through the access and thus the remaining composite is getting smaller and including the last light element or support element accesses the approach.

According to one embodiment of the invention, it is provided that in each case a certain number of the lighting elements is arranged on an elongated support body, preferably a rigid support rail, and a plurality of support body by means of

Movement device are movable. Such a construction is particularly useful when using light emitting diodes (LED), as to achieve a sufficient

Light output in this case, a large number of LEDs is needed and easier to handle by the carrier body as a unit, in particular to install and remove. In such equipped with LED Trägerkörpem are commercially available

Components.

Preferably, the lighting elements or the carrier body are connected by means of coupling elements hinged together.

In this way, a reversibly deformable composite of a plurality of

Illuminated elements created, which is not only rectilinear but also along curved trajectories movable. In this way, depending on the orientation of the

Illuminating elements in their assembled state on the one hand and positioning and orientation of access on the other side, achieve great freedom in the way of guiding the lighting elements to the access or the leadership of the same through the access.

The invention further ausgestaltend is provided that the coupling elements of

Sections of a traction means are formed, wherein preferably the portions of the Zugmittels are formed by a continuous, all lighting elements or carrier body interconnecting common traction means, wherein the traction means is preferably a rope, preferably made of metal or plastic or plastic encased metal, more preferably made of stainless steel, or a belt or a belt or a belt or a chain is.

A traction means is a force transmission member which can indeed transmit tensile forces, but due to its Biegeschlaffheit a rotational movement of adjacent lighting elements allows each other, so that the web of movement of a luminous element or the lighting elements or carrier body from the respective operating location to the access through or through this can be designed with quite a lot of freedom. So is without further z. B. also an s-shaped trajectory conceivable.

It is possible that a plurality of coupling elements and the carrier body or

Illuminating elements together form a matrix or lattice structure, wherein preferably parallel to each other extending carrier body or lighting elements are arranged perpendicular to mutually parallel coupling elements or rows of coupling elements. This results in a flat structure and arrangement of

Luminous elements, which is articulated at least about an axis, preferably parallel to the carrier bodies or lighting elements, so that there is a windability about such an axis. For example, a winding of the light-emitting elements or the carrier body about a shaft defining a winding axis may be possible.

As an alternative to winding into a spiral-shaped roller or roll, it is also conceivable for at least one traction means to form a self-contained "ring", preferably of at least one deflecting means, furthermore preferably in the form of a roller, roller or shaft, can be deflected

Move lighting elements on an approximately oval or trapezoidal (at different diameters of the deflection) trajectory. In the simplest case (with vertical alignment of the front elements), a deflection means is provided only in the region of the upper reversal section, and a deflection in the region of the lowest point results automatically by gravity due to the formation of a specific radius of curvature. The drive can be done manually in the simple case with the help of a wheel, a crank or a Betätigungszugmittels, such as a roller blind.

In the context of the invention, the at least one front element can be oriented vertically or horizontally and preferably made of a glass or plastic material or a concrete, plaster or clay provided with optical fibers (based on a polymer or silicate) or of a natural stone, in particular alabaster or onyx, or from a Sheet of particular Matallfasern, in particular in the form of a fabric, a knitted fabric, a knitted fabric or a nonwoven fabric, preferably made of Edeistahlfäden exist.

If all lighting elements or certain lighting elements, preferably in groups, electrically conductively connected to each other, in particular are connected in parallel, it is sufficient to solve a single supply or supply line to then move the light elements or the carrier body separately from the electrical power supply can. Preferably, a single supply line for all light elements should be solvable by means of a plug-in connection with the aid of one of the light-emitting elements or one of the carrier bodies or a line between two light-emitting elements or between two carrier bodies. In this case, you can relax

Termination of the replacement work just as easily restore the connection as it existed before the relocation of the lighting elements.

In addition to a manual execution of the movement device and an operation by means of a drive with external energy is conceivable, in particular electrical drives, preferably those with a gear motor, are advantageous.

According to a particularly advantageous embodiment of the invention, a radiation direction of the lighting elements by a movement of the light emitting elements of a first

Operating position in a second operating position variable, in particular by an angle 180 °. In this way, when commissioning the lighting installation with new lighting elements, it is initially possible to choose a first emission direction in which the light strikes a surface of the rear wall facing the front element and is reflected from there in the direction of the front element. This results in a particularly uniform fluoroscopy of the front element due to the greater diffusivity of the light through the reflection on the rear wall, so that a particularly good aesthetics of

Lighting installation is achieved. If, as a result of a degradation of the light elements, as occurs typically in LED's over time, the light intensity, as it passes in the outer environment of the lighting installation through the front element, too low, so by appropriate movement of the light-emitting elements

Direction of radiation can be changed so that the front element is directly illuminated, whereby the intensity, as can be seen in the external environment increases, because no more losses occur by the reflection on the rear wall. The increased intensity in the second emission direction is paid for by a possibly reduced one

Homogeneity of fluoroscopy.

Furthermore, a preferred development is that with the

Movement device, in particular a carrier element or a luminous element, at least one cleaning element is coupled or coupled, with which a space facing the gap surface of the rear wall or the ceiling and / or a space facing the gap surface of the front element can be cleaned. In particular, elongated brushes or nozzle strips which can be acted upon with a liquid cleaning agent are suitable for such a cleaning purpose, wherein the

Cleaning effect in the first case by a relative movement between the

Cleaning element and the surface to be cleaned and in the second case by a flat "sweeping" the surface to be cleaned with cleaning jets comes about.

In procedural terms, the object is achieved in that at least one luminous element (8), preferably successively several lighting elements (8) moves to the access (27) and then through the access (27) is replaced or be or at least a luminous element (8), preferably successively a plurality of lighting elements (8), through the access (27) passes through into the external environment and is replaced there, wherein adjacent lighting elements (8) via an articulated and / or releasable connection with each other are..

Preferably, an electrical supply line before the actuation of

Moving device separated from the at least one luminous element or a support element and after the replacement of the luminous element and after a return movement of the at least one luminous element again connected to the carrier element.

embodiment

The invention described above is described below with reference to two

Embodiments explained in more detail.

It shows:

1 shows a vertical section through a vertically arranged lighting installation in a first embodiment,

FIG. 2 shows a horizontal view of the lighting installation according to FIG. 1 after removal of the front element,

FIG. 3 shows an enlarged detail from FIG. 1 in the region of a deflecting roller,

FIG. 4a shows an enlarged detail from FIG. 2 in the region of an upper one

Mounting bracket, FIG. 4b: as in FIG. 4a, but in the region of the lower mounting angle,

5a shows a detail view of the upper mounting bracket and an upper guide plate,

Figure 5b: as Figure 5a, but the lower mounting bracket and the lower guide plate including a Nachspannvorrichtung, and

Figure 6: as Figure 1, but a second embodiment with only one arranged above

Deflecting.

A lighting installation 1 has a translucent, plate-shaped front element 2 in the form of a plate made of light-conducting concrete. In the light-conducting concrete are optical fibers in the form of glass fibers, which can be arranged distributed over a perpendicular to the plane of the drawing of Figure 1 extending front plane 3.

The front element 2 is arranged at a clear distance 4 from a front plane 5 of a rear wall 6, which is a wall of a building. The clear distance 4 is here typically between 15 cm and 30 cm. Due to the distance 4 between the front element 2 and the rear wall 6, a gap 7 is formed between the two aforementioned components.

In the aforementioned gap 7 is a plurality of light-emitting elements 8, which are attached to elongated support bodies 9 in the form of carrier rails. At each support body 9 are a plurality of light-emitting elements 8 in the form of light-emitting diodes 9 are arranged distributed equidistantly in the longitudinal direction of the support body. The units formed from luminous elements 8 and support body 9 are commercially available components and each provided with a single connection cable for power supply, which is not shown in the figures for clarity.

According to the invention arranged on the support bodies 9 lighting elements 8 are connected to a movement device 10, which consists in the first embodiment of two rotating traction means 11 in the form of steel cables, the traction means 11 are in turn deflected at an upper and at a lower guide roller 12, 13: The traction means 11 consists in each case of a single, long, "annular" closed section, on which the carrier bodies 9 are provided with suitable fastening means (eg.

Clamping screws) are held.

From the view according to FIG. 2, it can be seen that in each case a traction means 11 is arranged close to the edge at both ends of the carrier body 9. The guide rollers 12 and 13 are respectively mounted in upper and lower guide plates 14, 15, which in turn with the aid of upper and lower mounting brackets 16, 17 are anchored to the rear wall 6. The guide plates 14, 15 have, in mutually facing end portions, angled portions 18 which, in the manner of a funnel, enter the carrier body 9 in the deflection region of the respective one

Deflection roller 12, 13 prevent a stop of the ends of the support body 19, if they are unintentionally deflected laterally. It is possible, in the direction of a respective axis of rotation 9, 20 of the guide rollers 12, 13 to realize an axial guidance or fixing of the respective traction means 11, for. B. in the form of grooves in the respective

Deflection rollers 12, 13 or in the form of axially on the respective guide rollers 12, 13 pushed and fixed to the right and left of the respective traction means stop disks.

From the detailed view according to FIG. 3, it emerges that 8 light cones 21 emanate from the luminous elements fastened to the carrier bodies 9, whose lateral surfaces are illustrated by the intersecting lines 22 with the plane of the drawing in FIG. It can easily be seen that the lighting elements 8 emit in the direction of the rear wall 6 and not directly in the direction of the front element 2. The front plane 5 of the rear wall 6 is formed by a reflective layer 23, for example as a lacquer layer or paint

(preferably in each case in white or silver) or else as a foil (eg aluminum foil). In any case, the reflection properties of the frontal plane 5 should be as good as possible in order to absorb as little as possible of the light, i. H. to keep the light losses low. The light is thus reflected for the most part at the front plane 5 of the rear wall 6 and then falls on a back plane 24 of the front element 2 and penetrates the latter in the optical fibers embedded therein to the

To leave lighting installation 1 at the front level 3 of the front element 2.

In FIGS. 4a and 4b, the respective orientation of the bend 18 is the

Guide plates 14, 15 visible. In the mounting brackets 16, 17 are each two holes 25, which serve for anchoring the mounting bracket 16, 7 on the rear wall 6 by means of dowels and screws (not shown).

Again, it can be seen from Figure 1 that below the front element 2 a

Closing element 26 is arranged, with which an access 27 to the gap 7 can be closed or release, with the access 27 between the front element 3 and a floor 28 of the building is located. While the closure element in its closed position shown in FIG. 1 makes it impossible to see the gap 7 and the illumination device or movement device 10 located there, the access 27 is free after removal of the closure element 26, which preferably extends over the entire width of at least the carrier body 9. in order to carry out maintenance work on the lighting installation 1. Thus, for example, with a human arm through the access 27 through the traction means 11, in particular its take front strand, and pull down so that successively reach all the carrier body 9 with the associated lighting elements 8 in the region of the lower guide roller 13 and thus in a readily accessible through the access 27 area. During the movement of the traction means 11, the carrier body 9 successively shift to the rear wall 6 facing side of the traction means 1 1. The radius of the guide rollers 12, 13 is chosen to be correspondingly large for a deflection of the carrier body 9. If all support bodies 9 are displaced to the rear wall 6 facing side of the traction means, ie the traction means 1 1, starting from the position shown in Figure 1 moves exactly by half his rope length, emit all the lighting elements 8 in a rotated by 180 °

Direction, d. H. This can be advantageous after a certain period of operation of the light-emitting elements 8, because then the light output has decreased and by dispensing with the reflection (and absorption) at the

Rear wall 6 is a higher light output on the rear plane 24 of the front element 2 is available, though it may easily suffer from the homogeneity of the light distribution.

In FIGS. 5a and 5b, the wall mounting of the movement device 10 according to the invention is finally explained in more detail: As can be seen from FIG. 5a, the mounting bracket 16, which in turn is anchored in the rear wall 6, is attached to the upper guide plate 14 with its angled portion 18 , In the guide plate 14 is a slot 29 which is for receiving a pin, not shown in Figure 4a

Guide roller 12 is used. Due to the elongated hole 29, the upper guide roller 12 can be adjusted in height to produce the necessary tension in the traction means 11.

The lower guide plate 15 with its bend 18, however, has no slot for the implementation of a shaft journal (which is also not shown in Figure 4b) but only a bore 30. In contrast to the guide plate 14 is the

Guide plate 15 according to Figure 5b is not rigidly connected to the lower mounting bracket 17 but articulated by means of two mutually parallel pivot arms 31, on the one hand hinged to the guide plate 15 and on the other hand hinged to the

Mounting bracket 17 are attached. In this way it is possible to change the tension in the traction means 11, which is guided around the lower guide roller 13 through

Pivoting of the guide plate 15 in the direction of the curved double arrow 32. A post-tension can also automatically only due to the weight of the lower

Guide roller 13 done.

Each of the carrier body 9 is - as already stated above - with its own

Connection cable provided for connection to a power supply. All

Carrier body 9 are electrically connected to one another via a connection cable, not shown in the figures, so that a parallel connection of all carrier body 9 with its luminous elements 8 located thereon is present. At the bottom of the illustrated in Figure 1 vertical row of support bodies 9, a feed cable, not shown, is connected, which is connected to a power supply. Before the

Movement device 10, which is manually or by means of a drive, is set in motion, the aforementioned feed cable from the electrical network of

To solve carrier body 9. Then all support bodies 9 - while maintaining the electrical connections with each other - between each adjacent support bodies 9 are moved among themselves. In the case of the exchange of a whole carrier body 9 with all light elements 8 located thereon, only the disconnection of this single carrier body 9 from the electrical composite is required, whereas the other remaining carrier body 9 all together can remain electrically connected to each other.

The alternative embodiment of a lighting installation 1 shown in Figure 6 differs from that shown in the figures described above, as in the second embodiment, only an upper guide roller 12 is present, whereas at the bottom of the front run of the traction means 11 by means of a fixing .3.3 attached to the floor 28. The rear run of the traction means 11 is at a second

Fixing device 34 attached, which in turn is firmly connected to the rear wall 6. In this way, the traction device, which is guided over the upper guide roller 12, in the

held operating position, although gravity due to the

Carrier bodies 9 of the lighting device provided front run of the pulling means 11 would strive to fall down.

However, the rear run of the traction means 1 1 does not end at the fixing device 34 but has an excess length, which preferably corresponds to at least one height H of the rear wall 6 and the intermediate space 7. After loosening the rear run of the traction means 11 of the fixing device 34, the traction means 11 can be controlled while maintaining the tension of a person performing a revision be reduced, causing the located on the front run of the traction means 1 1 carrier body 9 successively downwards in the direction move the access 27 and accumulated there or can be successively pulled out of the gap 7. After completion of the

Inspection work, the released traction means 1 can then be withdrawn, causing the carrier body 9 go into its operating position. Then, the traction means 11 is fixed again to the fixing device 34. LIST OF REFERENCE NUMBERS
