Description

The invention relates to a lighting arrangement, in particular for strip light systems, according to the preamble of claim 1.

In high rooms and halls, for example in sports and games halls, warehouses and the like, lights are usually suspended and arranged as light strips for lighting reasons.

The suspension can be done with chains, pendulum tubes or ropes, which usually attach to the support rails of the lighting arrangements and are attached to suspension points on ceilings or ceiling structures.

The invention is based on the object of creating a lighting arrangement with a suspension which enables simple assembly with few tools and ensures particularly secure suspension.

According to the invention, the object is achieved by the characterizing features of claim 1. Useful and advantageous embodiments are contained in the subclaims and in the description of the figures.

The invention is based on the basic idea of using a rod suspension as a suspension structure or also with another suspension, for example a rope suspension.

to combine and hang on a connecting element.

According to the invention, the luminaire has a suspension structure which is formed by a rod suspension, which can be pre-assembled on a luminaire housing and, in the pre-assembled state, can be suspended in or on a suspension point, for example a connecting element of a cable suspension.

A rod suspension according to the invention has at least one pre-assembled rod, wherein this pre-assembled rod is formed by two rod legs, for example two clamping or spreading legs, which are held securely in a clamping and/or spreading position and in particular in an upright, assembly-friendly arrangement directly on the luminaire housing or indirectly via a mounting unit on the luminaire housing.

A particularly stable suspension that is secured against unhooking is achieved by having two rods that can be hooked into or onto suspension points that are bent in a U-shape or hairpin-like manner and designed as clamping or spreading rods. The rods can be fixed in a defined fastening arrangement for pre-assembly and mounted on the housing in an upward-facing assembly or suspension position.

The fastening arrangements of a rod suspension, which usually consists of two rods, can be designed as one-piece or multiple parts, in particular two-piece, and can either be already attached to the luminaire housing or can be fixed to the luminaire housing together with the pre-assembled rods.

In the case of a combined rod/cable suspension, which is particularly suitable for light strips, a connecting element suspended from cables is expediently used to hold the

Rods of a rod suspension. This makes it possible to hang and fix a luminaire housing with pre-assembled rod suspension in appropriately designed receptacles of the connecting element. For an advantageous assembly and hanging position, for example, U-shaped spreader rods are attached with the free ends of their spreader legs to the luminaire housing, in particular to a mounting plate or to a flat iron, in such a way that they are pointing towards the ceiling or connecting element.

A preferred rod suspension provides two U-shaped or hairpin-shaped bent rods, which are pre-assembled with free, angled leg ends in a fastening arrangement and fastened to the lamp housing in the pre-assembled state. A multi-part fastening arrangement is particularly easy to handle, whereby a two-part fastening arrangement is advantageous for a conventional rod suspension with two rods. Each rod, which is designed in particular as a clamping rod, is assigned a mounting plate and a clamping element, which form a fastening arrangement. The leg ends of a rod, which are angled in particular in a U-shape, are held in a clamp holder on the mounting plate. The mounting plate preferably has an opening for each leg end. A holding leg and a clamping web comprise the mounting plate. After a rod has been mounted in a mounting plate, this is completed with a clamping element in such a way that a clamp holder is formed in cooperation with the holding webs and grooves of the lamp housing.

It is advisable for the mounting plate, clamping element, retaining bar and groove of the luminaire housing to have complementary bends or recesses so that a secure clamping fixture is provided with the help of a fastening element. An alternative design provides for spreader bars, which are also attached to a

pre-assembled with a single or multi-part fastening arrangement and can be suspended or hung with a luminaire housing in the pre-assembled state.

To ensure that the spreader bars are securely fastened to the luminaire housing and in an upright position, for example to a mounting plate fixed to the luminaire housing or in a relatively narrow flat iron, which can be arranged in the front area between the longitudinal profiles of the luminaire housing, at least one spreader leg of each spreader bar is provided with an extension that is bent approximately at a right angle or in a U-shape. For example, a horizontal holding leg that runs almost parallel to the longitudinal axis of the luminaire housing when mounted and a clamping bar that points upwards at a right angle can be formed on an external spreader leg of a spreader bar that is arranged diametrically to the longitudinal axis of the luminaire housing. The external expansion leg, which forms a defined opening angle with an internal expansion leg arranged transversely to the longitudinal axis of the luminaire housing due to a springing force, is inserted into a particularly complementary assembly opening of a flat iron or a mounting plate for fastening to the luminaire housing, for which purpose both expansion legs of the elongated U-shaped expansion rod are first pressed together. The compressed expansion rod is then brought into an almost horizontal position and in this threading position the one or two-leg extension of the external expansion rod, i.e. the holding leg or the holding leg with clamping bar, is inserted into the assembly opening of the fastening surface, the flat iron, the mounting plate or the luminaire housing. The clamping bar can work together with another opening or alternatively with a clamping area on the mounting plate, the flat iron or also on the luminaire housing, so that a detachable

re fixation of the spreader bar and in particular its upright arrangement and position are guaranteed. The inner spreader leg, which is slightly shorter than the outer spreader leg, is inserted into a slot diametrically opposite to the longitudinal axis of the lamp housing when the outer spreader leg is threaded in. After the outer spreader leg has been anchored, the spreader legs are relaxed. Due to the specified spreading force between the spreader legs, the inner spreader leg is sprung onto the inner edge of the slot and held in a stable position in the slot. In contrast to the outer spreader leg, the inner spreader leg has a free, straight end. This allows a spreader bar to be aligned in a simple and advantageous manner and, depending on the requirements, the suspension angle formed between the spreader legs arranged parallel to the housing’s longitudinal axis and a horizontal base surface, for example the flat iron, can be varied. The clamping bracket of the U-shaped extension of the external spreader leg is not affected by these angle changes.

Such pre-assembled, upward-facing clamping or spreading rods can be suspended particularly advantageously by lifting the luminaire housing with the connection area as an upper point between the legs of each rod in receptacles, for example a connecting element, a hook, a ceiling structure and the like. As a rule, only one worker is required for this. Another advantage is the high level of security against the rods becoming unhooked during assembly of the luminaire housing with rod suspension.

When hanging a luminaire housing with rod suspension into a connecting element which is suspended from a cable suspension,

φ ·

is hung, the insertion openings of the receptacles are sensibly accessible from a base surface of the connecting element, which is designed in particular as an isosceles triangle, whereby a securing element can be actuated from an end surface of the connecting element.

In a practical design of a combined rod-cable support, the lower holding elements of the cable suspension are also arranged in the receptacles of the connecting element. By providing holes above the receptacles for guiding the cables and having a smaller diameter than the holding elements, which are particularly spherical, a safe and stable suspension of the connecting element and the rod suspension with light housing suspended in it is ensured. The upper holding elements of the cable suspension have devices for regulating the cable length and are arranged at a predeterminable distance on a ceiling-side fastening plate. For a particularly attractive design, it is recommended to cover the ceiling-side holding elements, devices for regulating the cable length and the ceiling-side fastening plate with a cover cap.

Alternatively, the devices for adjusting the length of the rope can also be incorporated into the connecting element and, for example, held in fastening areas or mounting holes that are formed above the mountings for the spreader bars. The ropes are suspended via upper, particularly spherical holding elements that are detachably fixed to a fastening plate of the ceiling-side suspension point. For quick and uncomplicated assembly and disassembly of the suspension, openings for the ropes and for the spherical holding elements are provided in the fastening plate and arranged in such a way that positional fixation is guaranteed.

• · · · Oil

The main advantages of the lighting arrangement according to the invention with a rod suspension or with a combined rope-rod suspension construction are pre-assembly of the rod suspension on the lighting housing and hanging of the lighting housing by a fitter with unhook-proof, pre-assembled rods in or on a suspension point or a connecting element that hangs from a ceiling-side suspension point and is, for example, height-adjustable. The simple and unhook-proof rod suspension with defined rods that are fixed in an upright position, which are arranged in particular axially symmetrical to the longitudinal axis of the lighting housing and on a one- or multi-part fastening arrangement, is particularly advantageous. This makes it possible to hang a lighting arrangement quickly and precisely with few tools and to advantageously form light strips.

In Fig. 1, a lighting arrangement 2 with a first variant of a combined rod-cable suspension is shown in a partially sectioned view. The lighting arrangement 2 is suspended from a ceiling 3 with the aid of a cable suspension 6 between a connecting element 31 and a ceiling-side suspension point 7 and a rod suspension 12 between the connecting element 31 and a lighting housing 4.

The cable suspension 6 comprises two cables 8, 9, which hang from a ceiling-side fastening plate 20 via upper holding elements 10 and/or devices 15 for regulating the cable length and thus for adjusting the height of the lamp housing 4 on the ceiling 3. The fastening plate 20 with the upper holding elements 10 and devices for regulating the cable length 15 are provided with an approximately cuboid-shaped cover 25, which is held on the ceiling 3, for example, via locking elements.

A connecting element 31 is suspended from the cables 8, 9 of the cable suspension 6, in which holes 38, 39 are formed for guiding the cables 8, 9 in an axially parallel arrangement. The holes 38, 39 lead into receptacles 36, 37 for two spreader bars 13, 14 of a bar suspension 12, so that each cable 8, 9 is assigned a spreader bar 13, 14. The spreader bars 13, 14 are arranged symmetrically to the longitudinal axis of the lamp housing 4 or the lamp arrangement 2 and are bent in a U-shape or hairpin shape. The spreader bars 13, 14 each have an inner spreader leg 23 directed towards the longitudinal axis of the lighting arrangement 2 and an outer spreader leg 24, which in the assembled state enclose an opening angle of approximately 3 to 12 degrees, wherein the intersection point formed by extending the spreader legs 23, 24 lies above the connecting element 31 approximately in the area of the cable suspension 6 or the ceiling-side suspension point 7.

In order to keep the spreader bars 13, 14 in an upright mounting position so that they cannot be unhooked, a holding leg 27 and a clamping bar 49 on the outer spreader leg 24 interact with complementary mounting openings 45 and clamping areas 50 on the luminaire housing 4 (see description of Fig. 4).

The spreader bars 13, 14, which are oriented obliquely upwards in the assembled state, are inserted with connecting areas 26 between the spreader legs 23, 24 into receptacles 36, 37 of the connecting element 31 and are secured with a horizontally fixable securing element 34, in particular with a retaining bolt. The securing element 34 (see Fig. 2) is inserted into a front opening 44 of the connecting element 31 and passes through the connecting area 26 of a spreader bar 13, 14 so that it is securely secured.

The receptacles 36, 37 are dimensioned in such a way that the spreader rods 13, 14, which are designed in particular as wire rods with a circular cross-section, can be inserted and also a lower holding element 11, in particular a molded, welded or pressed ball end of the cables 8, 9 is received and held. For this purpose, holes 38, 39 above the receptacles 36, 37 have a smaller diameter, which essentially corresponds to the cable diameter of the cables 8, 9.

Fig. 1 and Fig. 3 show the spread arrangement of the spreader rods 13, 14 and the axially parallel cable suspension δ with the cables 8, 9. In this embodiment, the rod suspension 12 is pre-assembled on a mounting plate 5 that is fastened between the longitudinal edges 17 of the lamp housing 4 and on retaining webs 43 of the longitudinal edges 17. This mounting plate 5 (see Fig. 4), which forms a one-piece fastening arrangement 5 for a rod suspension 12, is fastened diametrically to the longitudinal axis of the lamp arrangement 2 in the front area of a lamp housing 4.

Fig. 3 shows a fastening element 52 with which the mounting plate 5 is fastened to the opposing retaining webs 43. To accommodate the fastening element 52, a fastening opening 53 is formed in the mounting plate 5 (see Fig. 4).

Alternatively, a narrow flat iron can be arranged in the upper front area of a lamp, which can also be designed as a round lamp.

For identical features in Fig. 3, identical reference numerals from Fig. 1 have been adopted. A ceiling-side suspension point 7 has a fastening plate 20, to which the cable suspension 6 is attached via upper holding elements 10.

is hung. The lower holding elements 11 of the ropes 8, 9 are each fastened, for example screwed, with a device for rope length regulation 15 in receiving holes 47,48 of the connecting element 31. The receiving holes 47,48 of the connecting element 31 (see Fig. 5) have a diameter that is complementary to the device 15 and are formed above the receptacles 36, 37 for the spreader bars 13, 14 or for their connecting area.

The dashed representation of the left inner expansion leg shows the spring-apart force of the expansion legs 23, 24 of a spreader bar 13, 14, which in conjunction with a clamping position or anchoring of a spreader leg 24 in a fastening surface or device, e.g. in a mounting plate 5, ensures an unhooked, upright mounting or hanging position of the expansion bars 13, 14.

Fig. 4 shows a partial view of a mounting plate 5 with a fastening opening 53 for the fastening element 52, with which the mounting plate 5 is fastened directly to the holding webs 43 of the lamp housing 4. Between an elongated hole 46 and the fastening opening 53 there is a mounting opening 45, the circular diameter of which corresponds to the diameter of the expansion legs 23, 24 and in particular of the holding leg 27. This means that a certain degree of anti-unhooking protection and an upwardly directed arrangement of an expansion rod can be achieved. The arrangement and design of an external expansion leg 24 with a U-shaped or double right-angled extension 27, 49 is indicated. The approximately U-shaped extension, which is formed by the holding leg 27 and the vertically arranged clamping web 49, enables a clamping and spreading position of the expansion legs 23, 24 of the

Spreader bars 13, 14 are made possible, which is connected to an upright arrangement of the spreader bars 13, 14, so that the lamp housing 4 can be suspended with pre-assembled spreader bars 13, 14 with particularly little effort. The fastening of a spreader bar 13 takes place in the compressed state and in an approximately horizontal position of the spreader legs 23, 24 arranged next to one another and transverse to the longitudinal axis of the lamp housing 4.

The reason for the secure mounting of the rod suspension of the lighting arrangement according to the invention is, in addition to the clamping bracket of the outer expansion leg 24, the spreading force between the expansion legs 23, 24 and the straight end of the inner expansion leg 23, whereby different suspension angles α adapted to the requirements are made possible.

Figures 6 to 8 show a further alternative embodiment for a rod suspension according to the invention for a lighting arrangement. Identical reference symbols are used for identical features.

Fig. 6 shows a pre-assembled unit, which consists of a connecting element 31, a rod suspension 12 with two rods 13, 14 and a multi-part fastening arrangement 55. The rods 13, 14 are bent like a hairpin, analogous to the embodiments of Figs. 1 to 5, and are fixed in an aligned clamping bracket in the multi-part fastening arrangement 55, which consists of four parts. This clamping bracket is realized with angled leg ends 63, 64. The free leg ends 63, 64 of the rods 13, 14 are angled twice in the form of an elongated U in this embodiment and are clamped to a mounting plate 56. The insertion as well as the alignment of the rods 13, 14 and the leg ends 63, 64 corresponds to the rod suspension 12 of Figures 1 to 5.

The assembly unit according to Fig. 6 shows bars 13, 14 hanging parallel from the connecting element 31 with the multi-part fastening arrangement 55. This fastening arrangement 55 consists of a mounting plate 56 and a clamping element 57, which is arranged almost parallel above the mounting plate 56. A beveled area 59 on the mounting plate 56 and a clamping nose 65 on the clamping element 57 form a clamping bracket 60 for the assembly unit according to Fig. 6 with the help of a connecting element 62 (see Fig. 8).

This bracket-like clamp holder 60 is designed in such a way that the clamping nose 65 above the holding web 43 engages in a longitudinal groove 61 and the beveled area 59 of the receiving plate 56 below the holding web engages in a longitudinal groove 61. By guiding and fixing the connecting element 62 through aligned openings in the clamping element 57, in the holding web 43 and in the receiving plate 56, a particularly simple, time-saving and easy-to-use assembly of the prefabricated assembly unit according to Fig. 6 can be carried out.

The rod suspension according to the invention is particularly advantageous for use for lighting arrangements and light strips, but can also be used for hanging up and hanging other objects and components.
