Description

"Lighting system and luminaire for a lighting system"

The invention relates to a filament system according to the preamble of claim 1 and a luminous element for a filament system.

State of the art

Luminaires, in particular for neon signs are already in diverse .AUSgestaltung example. in the form of letters, lettering, symbols or the like. In one embodiment, for example, letters that can be illuminated by light-emitting diodes are mounted on a wall via fastening screws. The power supply is via a power cable, which supply the LEDs with electrical energy.

A corresponding luminous element for a neon sign is disclosed, for example ^, in German Utility Model DE 299 14 456 U1. The luminous element has a solid, the nominal contour shape of the • luminous body reproducing core plate of an opaque material, a plurality of individual inserted into respective mounting holes in the back of the core plate LEDs, which are connected to a power supply and the back with the LEDs tightly covering the cover plate. To attach such a filament to a wall or bearing plate Gewindestif.te are provided, which from behind on the Cover plate and a wiring space are screwed into corresponding threaded holes in the core plate.

The electrical connection is made via connecting cable.

Purpose and advantages of the invention

The invention . The object of the invention is to improve a luminous element system or a luminous element for a filament system of the kind described in the introduction, in particular with regard to the assembly.

This object is solved by the features of claim 1 and 11 «

In the dependent claims advantageous and expedient developments of the invention are given.

The invention is initially based on a filament system which comprises at least one luminous element, for example neon signs in shopfitting, for example a luminous letter or a luminous number, which is illuminated with low-voltage illuminants. In addition, fastening means for attaching the filament to a support structure, such as a wall or a support plate are provided. The core of. The invention is .darin, • that a supply of the filament with low voltage on the attachment means, ie without an additional ^' cable guides on a respective fastener of the fastener, wherein the fastening means comprise a plug connection with plug-in socket and plug. This makes it possible to attach a luminous element by simply inserting it on a surface, for example a panel wall, and at the same time to make electrical contact. Preferably, a power supply to the lighting means in the luminous element is created exclusively via the plug connections. In accordance with prepared connectors whole lettering can be plugged, making the assembly significantly easier, especially in terms of time compared to known systems.

Separate cable feeds to light sources in the luminaire can be completely eliminated.

As luminous body in particular all alphanumeric characters and icons and logos into consideration.

Preferably, there is a plug connection for each pole from a separate plug-in socket with plug-in part. However, it is also conceivable that both poles are provided on a pin-shaped plug-in part, which can then be contacted accordingly in a matching plug-in socket.

For example, male or female parts of several connectors are spatially through the _. Luminaire surface arranged separately on a luminous body. ^• ie, on the outer contour that defines the luminous bodies are spaced from each other by outer contour portions which are not tailored to the plug-in connections, separated, provided the male or female parts of the connectors. With more than two connectors, it is sufficient if only two connectors for supplying a plus and a negative pole for the power supply are energized and all other connectors are only for fastening purposes, but this must not be recognizable on the connectors from the outside. In a particularly preferred embodiment of the invention, at least two insertion parts are provided on the luminous element. These may include, for example, a lamellar connector.

Another possibility is that plug-in sockets are present on the lamp. Then, a corresponding counterpart of the connector must be provided on a support structure. It is also conceivable that both plug-in sockets and plug-in parts are present on a luminous element. For example, the energized connectors are designed so that the plug-in parts are mounted on the lamp, whereas plug-in sockets are present in the unpowered connectors on the lamp. This differentiation is possible.

The connector may also be formed as a hook connection in a manner that a plug is tilted introduced and after a tilt back the plug is locked in the plug-in socket. By the ^' weight of a filament, the connector is preferably held in the locked position.

For this to be possible, such plug connections should be arranged on a "virtual tilt axis".

In mounted on the support structure state, the plug-in socket can be particularly through the support structure. In this way, the mounted plug-in socket from the rear or from a rear side of the support structure, which is, for example, back to a front or visible side of the support structure, be accessible for fastening purposes and / or for electrical contacting of the plug-in socket. In particular, at the reaching up to the back of the part or on the part projecting thereon Plug-in be taken precautions to attach to the plug-in fasteners or contacting elements.

For attaching or contacting the plug-in socket to different thicknesses or in the plug-in direction differently thick support structures, for example, optionally an extension element for extending the plug-in socket can be attached in the insertion direction at the rear end of the plug-in socket. It is conceivable, e.g. a threaded rod which can be screwed into a matching bore at the rear end of the plug-in socket. The threaded rod screwed in the assembled state can reach up to the rear side of the supporting structure or survive slightly on this, even with a comparatively thick wall of e.g. greater than 40 cm wall thickness.

In a preferred embodiment of the invention, the plug-in socket comprises a plug-in sleeve for the plug-in part, wherein the plug-in sleeve is seated in a mounting bush, which is connectable via fastening members with the support structure. By this measure, the mounting bush made of electrically insulating material, whereas a power supply via the insertion takes place. For this purpose, for example, the insertion sleeve can be connected to the mounting bush via screw means. Hereby, the insertion sleeve can first be fixed in the mounting bushing. In addition, a wiring can be provided via the screw, so that a flow of current through the screw to the insertion is guaranteed. Thus, a plug-in part in the insertion sleeve is contacted electrically in the end. In the case of a luminous element, a plug-in part or a plug-in socket is preferably on the side of the luminous element which is opposite the visible side hidden from the visible side.

In this way, not only an attachment of a filament visually in the background, but also their electrical supply, which is provided by the corresponding fastening means in the same way. For example, elements for three connectors corresponding to the letter contour are distributed on the side opposite the visible side on a luminous letter. According to ^' counterparts are then arranged on a support structure matching the elements of the connector on the letter. In plan view, the elements of the plug-in connection ^■ preferably be within a radius of 20 mm, preferably 15 mm. Even better are 10, 8 or even 5 mm.

In a particularly preferred embodiment, the insertion part comprises screw means which are screwed into the luminous body. The screw means may then have a plug structure, e.g. a lamellae are applied, possibly also by screwing.

As with a luminous body, a plug-in part can also be formed on a support structure.

Plug connections can be placed distributed along the contour with respect to the luminous element for a uniform attachment of a filament.

Description of the embodiments

FIG. 1 shows a plan view of an arrangement of letters 1 to 6 on a mounting wall 7. By the letters _. 1 to 6 are illuminated letters of preferably translucent, milky material, in which LEDs are integrated to their illumination. The structure of such letters can be of many types. For example, the front side of the letters is made opaque, whereas a light emission can take place on the side and on the back / whereby the letters appear in a kind of light corona in the illuminated state. Also conceivable is only an exit on the Back, with which a lighting let the letters float, so to speak optically.

Decisive is, regardless of the design of the letters whose power supply. All letters 1 to 6 are fastened to the mounting wall 7 via three plug connections 8, 9, 10, which are indicated in FIG. 1 by a square symbol. Two of the connectors, e.g. 9 and 10 at the same time ensure the power supply of the letters to their attachment property. The connector 8 can still be designed exactly the same, but this is not absolutely necessary, if necessary, but simplifies the production.-

The structure of a connector 9, 10 can be seen in Figures 2 and 3.

The connector 9, 10 comprises a plug part 11 of a lamellae IIa and a threaded rod IIb, which is assigned to the letter. For this purpose, the threaded rod IIb is screwed into a suitable sleeve llc in the letters 1 to 6, in such a way that thereby an electrical connection to the lighting means is created. For example, thereby the positive terminal of the illuminant is .kontaktiert .. On the protruding ^• the area of the laminated plugs Gewindestange1Ib IIa is screwed. This has resilient contact blades Hd, which are slightly compressed during insertion into a mating bore 12a of a contact sleeve 12 of the curved shape and thereby a clamping force arises.

The contact sleeve 12 is seated in a mounting sleeve 13, which is fastened with a nut 14 shown in dashed lines in a bore ^■ 15 of the mounting wall 7. In addition to the nut 14, a shim 14a may be provided. At the Screwing the nut 14 on a threaded portion 13 a, a collar 13 b, which covers the bore 15, clamped against the mounting wall 7.

^• In the mounting sleeve 13, the contact sleeve 12 is inserted, wherein a screw 16 with spring-loaded tip 16a is arranged so that the spring-loaded tip when inserting the contact sleeve 12 into a notch 17 on the contact sleeve 12, whereby the contact sleeve 12 is mechanically fixed. In addition, an electrical contact to the contact sleeve 12 is provided by the contact screw 16 with a pole of the electrical power supply (not shown) is in communication.

For a negative terminal, a second connector is designed accordingly and connected to the letter. The connectors 9, 10 are spatially completely separated from each other .An opposite edge regions of each letter 1 to 6 arranged.

In this way, a very simple arrangement of letters 1 to 6 on prepared sockets 1-8 is realized.

Heretofore, such advertising elements have been attached in a manner that they are not easily removable from a mounting wall 7. By contrast, if advertising elements can simply be removed, they can be used e.g. defective advertising elements are exchanged in the simplest way, even by a non-specialist. After subtracting the "old, defective" advertising element, the new advertisement must be inserted. This completes the assembly process.

Figure 4 shows an alternative embodiment of a contact sleeve 19.im longitudinal section, the part of an alternative inventive connector is. The contact sleeve 19 is continuously provided with a diameter-changing hole 19 a. In addition, the contact sleeve 19 is designed at the front with a collar 19b, which rests in a mounted on a mounting wall 20 state on a front side 20a of the mounting wall 20 (see Figure 5). The bore 19 a of the contact sleeve 19 is provided in its rear portion with an internal thread 21. About the internal thread 21 in the bore 19 a, for example, a threaded rod can be screwed to extend the contact sleeve 19 to the rear. The screwed threaded piece (not shown) can serve to extend the contact sleeve 19 for attachment or contacting on a mounting wall, which in its thickness exceeds the length of the contact sleeve 19.

In its thickness d in the insertion direction of the contact sleeve 19, the mounting wall 20 according to FIG. 5 is smaller than the length of the contact sleeve 19. On the contact part 19, which projects beyond a rear side 20b of the mounting wall 20, a fastening flange 23 is provided on the contact sleeve 19 via an external thread section 22 so screwed ^'that the contact sleeve 19 is firmly fixed to the mounting wall 20th In this case, the collar 19b is pressed against the front side 20a of the mounting wall. Thus, the mounting flange 23 can not be detached from the contact sleeve 19, for example, by vibrations, 23 holes 24 are provided in the mounting flange, which can be fixed by means of fastening elements of the mounting flange 23 on the mounting wall 20. This is exemplified in Figure 5 using a mounting screw 25 in one of the holes 24 shown. LIST OF REFERENCE NUMBERS
