Description

The present invention relates to a lighting device for illuminating a room area, in particular for illuminating a playground island, with a translucent viewing panel of at least partially transparent material, and a panel holding device having holding means for holding the viewing panel and fastening means for ceiling or wall mounting of the viewing panel.

The document DE-A-102009001170 discloses a lighting device according to the preamble of claim 1.

In large-scale situations, ie large, non-partitioned premises, it is desirable to illuminate the orientation of visitors to illuminate individual sub-areas of such large spaces accentuated and highlight other areas of space. Such large-scale situations are given, for example, in casinos and gaming halls, in which groups of gaming devices are sometimes combined to form so-called gaming device islands which, for example, each offer a comparable game type and thus can form a game theme island. The corresponding play equipment islands are on the one hand to be highlighted against the open spaces or aisle areas located between the play equipment islands, on the other hand, the corresponding playground equipment to be dipped in an atmospheric light, for example, a dramatic lighting situation for suspense gambling establishments or cheerful, friendly light for amusement games etc.

In order to ensure the visibility of the often equipped with screens game equipment and to allow for the eyes fatigue-free operation of the game equipment, it is desirable to have an at least reasonably uniform light intensity distribution at the same time glare freedom in the illuminated area. For this purpose, it is advantageous if the lighting device, which is usually to install due to the architectural space conditions on the play equipment islands, comprises a large-scale viewing panel, which evenly illuminating the light radiates into the desired space area. A sufficient large area allows sufficient brightness even with relatively low luminance, which allows a well perceptible accentuation of the corresponding space area with simultaneous glare.

Such large-area, lichtabstrahlende or transilluminable Sichtpanele are not readily installed in the respective building spaces, especially if the installation is done later in already existing ceiling structures and already set up devices or exhibits in the area to be illuminated space. For example, in casinos or arcades often already ceiling lights, for example in the form of spotlights or fluorescent tubes available and already installed on the corresponding playground islands game equipment, so that in the subsequent installation, the existing ceiling structure and their dimensions are to be used. The already established playground equipment must not be polluted or removed, which prohibit major alterations to the ceiling construction and can hardly use larger lifting devices for lifting larger lighting fixtures for mounting on the ceiling.

The present invention is based on the object to provide an improved lighting device of the type mentioned, the disadvantages avoids the prior art and the latter in an advantageous manner. In particular, it should also be possible to create a lighting device which is easy to install even given a given room design, which allows for clear visibility and fatigue-free operation or viewing of devices or exhibits exhibited there, and is variably adaptable to different accentuation wishes.

According to the invention, said object is achieved by a lighting device according to claim 1. Preferred embodiments of the invention are the subject of the dependent claims. In particular, the lighting device can be used to illuminate a game device island according to claim 14.

It is therefore proposed to assemble the transilluminable viewing panel from a plurality of viewing panel parts and to fix the viewing panel parts by a spider-like retaining arm arrangement which holds the viewing panel parts against the adjoining insides. The weight forces the Sichtpanelteile be intercepted from the inside or the spider-like Haltearmanordnung the viewing panel, so that even with large-scale Sichtpanelen only limited bending moments act on the Sichtpanelteile, which in turn allows the use of thin Sichtpanelteile and makes the use of high-strength materials unnecessary.

According to the invention, the holding means of the panel holding device have at least three interconnected star-shaped holding arms which hold at least two sight panel parts with their inner sides adjacent to each other so that the sight panel parts together form a substantially continuous panel surface, the panel parts being separated from the support arms have naughty, free outsides, which together form the outer periphery of the viewing panel.

By juxtaposing several Sichtpanelteile not only the desired large area of the viewing panel can be achieved at the same graceful appearance, but also a modular design, the interchangeability individual Sichtpanelteile and the variable combinability of various Sichtpanelteile allows. As a result, many different viewing panel surfaces and thus many different light atmospheres can be created with a limited number of different viewing panel parts. At the same time, the central introduction of force on the insides of the viewing panel parts and the resulting low bending loads allow the use of inexpensive, adapted to the lighting task viewing panel materials with high transparency and luminosity, which can cause sufficient light levels in the illuminated space even at low power of the lamps used. Alternatively, additional punctiform arranged or attacking holding and / or support elements may be provided, for example in the respective mass or area center of one or each panel part.

In this case, the holding arms can extend exclusively in the interior or an inner region of the viewing panel, wherein the viewing panel parts of the holding arms can have disgusted, free outer sides, which together form the outer periphery of the viewing panel. The viewing panel parts may be mounted alone on their inner, facing viewing panel edges, while the outer, the outer edge of the viewing panel forming Sichtpanelränder are cantilevered or cantilevered or project. Such unfinished on the outer peripheral sides or stunned formation of the viewing panel allows on the one hand with a light, transparent appearance of the viewing panel a shadow-free, soft transition room illumination, while on the other hand, the interchangeability and ease of installation of the lighting device is improved. Due to the absence of retaining elements on the outer peripheral sides of the Sichtpanelteile can be easily replaced or mounted, in particular attached from the outer peripheral side of the support arms or inserted into the holding device.

A better weight support even with large Sichtpanelen can in further development of the invention by a subdivision of the viewing panel in a sufficient number of Sichtpanelteilen and / or a correspondingly large number of retaining arms be achieved. In principle, the number of retaining arms and the number of sight panel parts can vary, wherein in an advantageous development of the invention between three and ten retaining arms and / or between three and ten sight panel parts are provided. On the one hand to avoid a multiplication of the assembly steps, but on the other hand to achieve a sufficient support effect in large-scale Sichtpanelen, three to six, in particular four support arms can be provided in an advantageous embodiment of the invention, holding three to six, especially four Sichtpanelteile.

In order to achieve a simple assembly and interchangeability of the sight panel parts, the retaining arms are formed and arranged in such a way that the Sichtpanelteile can be inserted from the outer peripheral side in the spanned by two adjacent support arms sector and attached from the outside to the support arms , In particular, each adjacent two retaining arms limit a Sichtpanelsektor that tapers to the junction of the two adjacent support arms out and its lateral sector edges are formed in the direction of said junction to undercuts. This makes it possible to insert the respective Sichtpanelteil from the outside in the spanned by the two adjacent support arms space area and attach to the support arms without the Sichtpanelteil would clamp.

Alternatively or additionally, however, it can also be provided that the respective viewing panel part is attached to the said retaining arms from an underside or, in particular, from an upper side. This could be dispensed with the mentioned undercut-free design of the support arms. When inserting the viewing panel parts transversely or perpendicular to a plane which is spanned by the retaining arms, the retaining arms may be arbitrarily contoured per se, in particular curved arcuate or otherwise deviate from a straight line.

In an advantageous embodiment of the invention, said holding arms may have an at least approximately straight course and in pairs each limit a V-shaped Sichtpanelsektor. The retaining arms limit the lateral, diverging legs of the Sichtpanelsektors in which then a corresponding Sichtpanelteil can be used.

The anchoring of the viewing panel parts to said holding arms can in principle be achieved in various ways. In order to keep the Sichtpanelteile as stress-free and accordingly to use voltage-sensitive materials for the Sichtpanelteile, the support arms may have positive retaining elements in particular in the form of holding projections and / or retaining recesses advantageously embrace the respective Sichtpanelteil at the edge of at least two edge sides. Alternatively or additionally, a frictional, in particular clamping attachment of the viewing panels could be provided. However, in order to be able to use, for example, also sensitive glass for the visible panel parts, the retaining arms are advantageously provided with tension-free holding, preferably form-fitting retaining elements.

In particular, the holding arms can each open to opposite sides, preferably groove-shaped, holding recesses, so that from opposite sides two viewing panel parts lying back-to-back lying or narrow side-to-narrow side can be inserted into the retaining recesses and thereby to the between the Viewing panel parts lying holding arms can be attached. The said groove-shaped retaining recesses may in this case be formed continuously in the sense of a continuous channel. Alternatively or additionally, the said retaining recesses may also extend only in sections, for example in the form of a plurality of spaced, grid-shaped arranged retaining projections, hooks or retaining ribs on which rest the Sichtpanelteile. The open profile shape of the retaining recesses may in principle be contoured differently, for example, a Holding recess may be formed by a cross-sectionally L-shaped retaining profile, on the lying leg, the respective viewing panel can rest.

In an advantageous embodiment of the invention, however, the holding elements of the holding arms are designed such that the Sichtpanelteile are embraced from opposite sides. As a result, the Sichtpanelteile be held reliably and secured against falling. In particular, the holding arms can each be designed as extruded profile with H-shaped cross-section. As a result, with a minimum spacing of adjacent viewing panel parts, a secure holding of the viewing panel parts can be achieved. At the same time, the retaining arms can be manufactured inexpensively.

In order to mount the panel holding device with the sight panel parts attached thereto to a ceiling and / or a wall, possibly also to a lamppost-like or arrow-like support part, the retaining arms have at their side remote from the visible side of the viewing panel rear fastening means for fastening tie rods, the different may be formed, for example in the form of limp traction means such as ropes or chains, or in the form of rigid tie rods such as bars or struts.

In order to achieve a simple adaptability of the holding device to different mounting situations and mounting structures, the holding arms advantageously each have a plurality of grid-shaped distributed arranged fastening means for fastening tie rods for wall or ceiling mounting. Due to the large number of differently positioned fastening means, the corresponding tie rods can be fastened to the retaining arms in a suitable manner and in a suitable position as a function of predetermined fastening points, for example on a ceiling structure.

The said fastening means for fastening the tie rods to said holding arms are advantageously detachable, in order to be able to displace the tie rods in a corresponding manner.

In order to enable a stable installation of the viewing panel, even in the event of vibrations or wind pulls, the panel fastening device advantageously comprises retaining bars which can be fixedly connected to the retaining arms, in particular rigidly connectable, so that the retaining arms form a rigid support structure together with the tie rods or holding rods fastened thereto. For example, rigid tie rods can be rigidly but releasably secured by threaded bolt connections to the support arms, said bolt connections being provided on the non-visible sides of the support arms.

In order to construct the panel holding device modular and variable to redesign, the plurality of holding arms of the panel holding device can be made separately from each other and connected to each other by a common, cross-shaped fixing element. For this purpose, the retaining arms are advantageously rigidly fastened to said fixing element, so that they project from the fixing element in a star-shaped or radially outward direction. By such a central fixing or connecting element, the retaining arms can be made as a rod or endless product, in which case for the particular panel to be created holding arms are deflected in the desired length of the endless goods. The central fixing element is in this case advantageously designed such that the retaining arms can be arranged in a common plane, in particular such that in two adjacent retaining arms formed retaining recesses for a Sichtpanelteil converge on said fixing element.

The retaining arms can be attached to said cross-shaped fixing element in principle in various ways, for example, be welded. In order to avoid distortion during manufacture by thermal loads, however, the retaining arms can also be screwed, riveted or mounted in other form-fitting and / or frictionally engaged.

The viewing panel parts can in principle be made of different at least partially transparent, transilluminable materials, for example of glass. In an advantageous embodiment of the invention, the Sichtpanelteile can be made of plastic, such as polycarbonate.

In order to achieve an accentuated illumination of the assigned spatial area with uniform light intensity distribution, the viewing panel parts may have an iridescent coloration or turbidity such that different sections of a viewing panel part have different colors and / or different degrees of transparency, advantageously the transitions between the areas with respect to coloring and However, the degree of transparency is smooth and intertwined and no abrupt changes in the degree of transparency or color changes are envisaged.

The lighting means for backlighting or fluoroscopy of the viewing panel can basically be chosen differently and do not necessarily have to be part of the assembly comprising the viewing panel and the panel holding device. For example, the viewing panel with the panel holding device can easily be pre-faded in front of existing bulbs, for example in the form of fluorescent tubes, which are mounted on the ceiling, so that the viewing panel is irradiated and illuminated by the conventional, existing ceiling lighting.

Alternatively or additionally, however, the lighting device may also comprise lighting means which are fastened to the panel holding device and / or to the viewing panels. For example, the tie rods attached to the support arms can simultaneously form carriers for radiators or other lighting means.

Alternatively or additionally, the lighting device can also comprise light sources integrated in the holding arms, preferably in the form of point light sources such as LEDs, for example, which introduce their radiated light into the light panel parts via the narrow sides of the light panels. In particular, at the bottom of the be provided groove-shaped retaining recesses of said holding arms LEDs, which are positioned on the front side of the display panel parts used in the retaining recesses and bring the Sichtpanelteile so to speak from the inside to light up.

The illumination device 1 shown in the figures comprises a large-area viewing panel 2, which consists of at least partially transparent material and is transilluminable so that light emitted by the viewing panel 2 illuminates a defined spatial area 4. As Fig. 5 shows, the lighting device 1 advantageously be used in a casino or a game room, in order to illuminate there in particular a game device island 5, in which a plurality of game devices 6 are combined. The viewing panel 2 is advantageously adapted in size to the size of the playground equipment island 5, wherein a diameter of the viewing panel 2 on the order of magnitude may correspond approximately to the diameter of the playground equipment, but may also be smaller or larger depending on the size of the playground equipment island. Typically, the viewing panel 2 may have a diameter of one to five meters.

The viewing panel 2 is advantageously made of at least partially transparent material such as glass of a transparent plastic such as polycarbonate. Alternatively or additionally, however, also visible panel parts may be provided from a per se opaque material having a perforation or recesses, for example in the form of a perforated plate or a grid structure. Advantageously, the viewing panel can consist of transparent plastic disk parts which have an iridescent transparency or coloration, wherein sections of different transparency or different colors can have transient transparency gradients or color gradients merging into one another, as can be Fig. 2 shows.

According to one embodiment, the at least partially transparent material of the viewing panel 2 with a suitable film on one and / or both sides over the entire surface or at least partially be glued to allow more special lighting effects. The film may preferably be a transparent plastic substrate with a photoemulsion, for example a DURATRANS ™ material or a DURACLEAR ™ material.

The viewing panel here is advantageously approximately plate-shaped, in particular flat. However, the viewing panel can also have a slightly bulbous, cup-shaped contouring.

As the Fig. 1-3 show, the viewing panel 2 may advantageously be composed of several Sichtpanelteilen 2 a, 2 b, 2 c and 2 d, which together a form approximately continuous viewing panel. The viewing panel parts are adapted to one another in such a way that they complement each other in a puzzle-like manner to form a continuous visual panel surface. Advantageously, the viewing panel 2 is hereby subdivided into viewing panel parts which are congruent to each other, wherein the said viewing panel parts can advantageously form sector sections contoured in the shape of a V. In the illustrated embodiment, the viewing panel 2 in this case has a circular outer contour. However, it is understood that the viewing panel 2 may also have a different outer contour from the circular shape, for example in the form of a rectangle, in particular square, but also other rounded contours such as ellipses or ovals, or other polygonal contours such as hexagon. The viewing panel parts 2a, 2b, 2c and 2d in this case advantageously have mutually contoured side flanks, in particular in the form of V-shaped side flanks spread at the same angle. On the outer contours 2o of the Sichtpanelteile may be congruent to each other, but this may vary, ie, the outer contours 2o may be contoured differently from each other, for example, when a total of the outer circumference ago oval or elliptical viewing panel should be formed.

The display panel parts 2a, 2b, 2c and 2d are held by a panel holding device comprising, from a center, star-shaped support arms 9 extending between the adjacent inner sides 2i of the display panel parts 2a, 2b, 2c and 2d. As Fig. 1 and Fig. 3 shows, the support arms 9 may be formed in the form of narrow carrier strips which surround the viewing panel parts 2a, 2b, 2c and 2d on the inside edge side. Advantageously, the said retaining arms 9 have a straight course, the retaining arms 9 advantageously extending radially at equal pitch angles from the center of the viewing panel 2 to the outside.

As Fig. 3 shows, the support arms 9 in the center or in a central connection point 10 by a common fixing element 15 are rigidly connected together. Said fixing element 15 may comprise cross-shaped or star-shaped projecting fastening struts 16 which conform to the retaining arms 9 are and to which the said support arms 9 can be rigidly fixed, for example, can be screwed or riveted. Alternatively or additionally, between the holding arms and the fixing element 15 and a respective positive connection can be provided, for example in the form of a male profile connection, which allows the retaining arms 9 in the mounting struts 16 of the fixing element 15 or vice versa to insert the mounting struts 16 in the support arms 9.

The retaining arms 9 are advantageously designed in the form of extruded profiles, which may have an H-shaped cross section with retaining recesses 12 which are open towards opposite sides. As Fig. 4 , there shows the detail A, the retaining recesses 12 may form continuous groove-shaped slots, which are bounded by two spaced, substantially parallel retaining webs, between which inserted the Sichtpanelteile accurately into the slot-shaped retaining recesses 12 of the H-shaped contoured retaining arms 9 or inserted can be. Alternatively, the retaining arms 9 may be in the form of U-shaped cross-sectional extruded profiles, wherein two U-profiles are arranged back-to-back with retaining recesses 12 open towards opposite sides and interconnected, for example welded, riveted and / or glued. The retaining recesses 12 are adapted in terms of their dimensions to the thickness of the Sichtpanelteile, in particular such that the Sichtpanelteile 2 a, 2 b, 2 c and 2 d can be used with a light clearance or under a slight interference fit.

Advantageously, the retaining arms 9 are formed very narrow in the form of elongated, thin struts, so that they only slightly separate the Sichtpanelteile from each other. Viewed in cross-section, the retaining arms 9 may have a width which corresponds approximately to 100% -300% of the thickness of the Sichtpanelteile.

The holding arms 9, which are rigidly connected to one another in the central connecting point 10, carry a plurality of fastening means distributed in a grid-shaped manner on their upper sides or rear sides, which faces away from the visible side of the viewing panel 2 13, to which tie rods 14 can be rigidly fixed preferably in the form of bending-resistant tie rods. As Fig. 1 shows, the said tie rods 14 may extend substantially perpendicular to the plane of the viewing panel 2 of the support arms 9 away. Depending on the existing connection dimensions, for example, on a ceiling, the tie rods 14 can be attached to the support arms 9 at various locations. The said fastening means 13 may be, for example, bolts, in which the tie rods 14 are screwed.

While Fig. 1 shows only such a tie rod 14, it is understood that a plurality of tie rods 14 may be evenly distributed over the viewing panel 2 and the arrangement of the support arms 9.
