'Elongated lighting arrangement'

-i-

The present invention relates to an elongated lighting device comprising at least one elongated profile part on which holding means for holding lamps and/or installation units for lamps as well as a cable routing area are formed.

A lighting device of the type mentioned at the beginning is known from the European patent application EP 0 720 2 64 A2. The lighting device described therein uses an H-shaped profile part which has inwardly extending projections in its lower area onto which, for example, installation parts such as ballasts or the like can be placed. Furthermore, lights or other installation parts such as fans or the like can be attached in the lower area. Above the crossbar of the H-shaped profile, a cable duct is formed through which supply lines to the lamps and also to the other installation parts can be led. Furthermore, projections are formed on the outer sides of the profile which form fastening rails into which, for example, ceiling panels of suspended ceilings can be inserted in such a way that the ceiling panels can be held between two lighting devices running parallel to one another.

A disadvantage of the lighting device known from the prior art is that it can only be adapted to local conditions with great inflexibility; in particular, the lighting device cannot be designed to be so wide that it itself serves as a housing for lights installed in the lighting device, for example.

The problem underlying the present invention is to create a lighting device of the type mentioned at the beginning, which can be adapted more flexibly to local conditions.

This is achieved according to the invention in that the lighting device comprises two separate profile parts which, in the position of use, are located laterally opposite one another and parallel to one another in the longitudinal direction of the lighting device and which can be connected to one another at a distance from one another by connecting means or are connected to one another. The width of the lighting device can be changed as required on site by means of the two profile parts which are separated from one another, so that the lighting device can be adapted to the local conditions.

It can be provided that the profile parts can be connected to one another by means of a suspension unit, which also serves to suspend the lighting device from the ceiling of a room. This suspension unit can be designed in different widths, so that depending on the selected distance between the profile parts, a suspension unit corresponding to this distance can be used.

According to a preferred embodiment of the present invention, the suspension unit simultaneously serves to connect the profile parts of a first section of the lighting device to the profile parts of a second section of the lighting device that adjoins this section in the longitudinal direction. The suspension unit thus fulfills a triple function, namely the suspension of the lighting device, the connection of two profile parts in the transverse direction of the lighting device and the connection of two profile parts in the longitudinal direction of the lighting device.

It can be provided that the individual sections of the lighting system are, for example, five to six meters long. The suspension units connecting the sections can be used to create elongated lighting systems that are, for example, 25 to 30 meters long.

It can be provided that the suspension unit is a substantially narrow strip which extends in the transverse direction

of the lighting device. This ensures that the suspension unit is essentially only arranged in the connecting areas of the individual sections of the lighting device. In the other areas of the lighting device, the user on site is completely free to design the lighting device, particularly with regard to access to the lighting device from above.

According to the invention, it can be provided that the profile parts have sections of the cable guide area on their upper inner sides that protrude into the interior of the lighting device, wherein the suspension unit can be connected to at least one of these sections. Thus, the aforementioned sections of the cable guide area also have a dual function, namely on the one hand the formation of the cable guide area and on the other hand the connection of the profile parts to the suspension unit.

The suspension unit preferably has outer sections in the transverse direction of the lighting device, which engage under at least one of the sections of the cable guide area. This results in the profile parts being held securely by the suspension unit. Alternatively, the suspension unit can also rest on one of these sections of the cable guide area. In this case, the section of the suspension unit resting on top must be connected to the corresponding section of the cable guide area, for example with a screw connection.

In addition to or as an alternative to the suspension unit, the opposing profile parts can be connected to one another by a lower cover. Such a lower cover can thus contribute to additional stabilization of the lighting device. On the other hand, the cover can also conceal the interior of the lighting device for the user.

According to a preferred embodiment of the present invention, the cover has thickened sections and thinned sections in the transverse direction of the lighting device, which preferably alternate with one another in the transverse direction of the lighting device. On the one hand, the alternating thickened and thinned sections result in a visually appealing appearance of the lighting device. On the other hand, the thinned sections can be used by the user to cut the cover along these thinned sections using simple means. In this way, the cover can be brought to a desired width on site using simple means, so that the cover connecting the profile parts can be adapted to the desired distance between the profile parts using simple means.

According to a preferred embodiment of the present invention, the profile parts have projections on their inner sides facing one another that extend in the longitudinal direction of the lighting device and form fastening grooves. These fastening grooves can be used to hold a wide variety of parts of the lighting device.

In particular, the lighting device can comprise holding units which are provided with suitable fastening means for the holder in the fastening grooves. Installation means such as ballasts or transformers as well as lights can be held on these holding units.

The holding unit can have engagement parts on its outer sides that can be inserted into fastening grooves that are opposite one another. Alternatively, the holding units can have flat sections on their outer sides facing the profile parts that can be inserted into the fastening grooves. The holding unit could, for example, consist of a flat sheet metal part whose

outer sections can be inserted into the fastening grooves. Ballasts or the like could then be screwed onto this sheet metal part. Such holding units represent very flexible versions of a holding unit that can be adapted to different widths and are very cost-effective to manufacture.

It is also possible for the holding unit to have a U-shaped profile in the transverse direction of the lighting device, which can encompass the cable guide area of one of the profile parts from the inside of the lighting device in such a way that the holding unit is held on the corresponding profile part. Such a U-shaped holding unit also represents an embodiment of a holding unit that is extremely easy to adapt to local conditions and inexpensive to manufacture. In particular, this holding unit can be attached to one of the profile parts, so that it is completely independent of the distance between the profile parts.

According to the invention, it is possible for the holding parts to hold lights which have arms which project upwards and outwards beyond the profile parts and which carry light sources.

According to a preferred embodiment of the present invention, the profile parts have shoulders extending towards one another at their lower ends. A linear light extending in the longitudinal direction of the lighting device can be placed on the shoulders extending towards one another, which are opposite one another. These shoulders thus create a very simple holder for a linear light or for other parts required in the lighting device. With a linear light installed in this way, the cover in the area of the linear light can then be removed.

-6-

Furthermore, the steps that extend towards each other on opposite sides of the profile parts can be used to support the lower cover. The cover can either be placed loosely on these steps or screwed to the steps or connected in some other way.

According to a preferred embodiment of the present invention, the profile parts have at least one fastening rail on their outer sides. Additional parts such as hanging parts for advertising posters or fastening means for ropes or the like can be attached to the fastening rails, wherein adjacent lighting devices according to the invention can be connected to one another in particular by such ropes. Advertising posters or the like can then also be attached to such ropes. In addition, adjacent lighting devices can also be connected to one another by parts of suspended ceilings, which can also be attached to these fastening rails. In addition, it is possible to attach color markings to these fastening rails, for example, in order to color-code certain areas, for example in a hospital or the like.

The lighting device can additionally comprise a socket unit, which can preferably be clipped onto the cable routing area using suitable attachment sections. Such a socket unit increases the variability of the lighting device according to the invention.

According to the invention, it can further be provided that, in addition to supply lines for lamps, other cables, such as telecommunications cables, computer cables, power cables, cables for connecting or supplying installation elements or the like, can also be led through the cable routing area. In addition

&iacgr; * &igr; : &iacgr;&igr;

-7-

It is possible to attach additional installation elements such as loudspeakers, microphones, sockets, motion detectors, surveillance cameras, emergency and warning lights, smoke or gas detectors and the like to the lighting device, particularly in the area of the cover. The lighting device according to the invention can thus be used very flexibly and can meet a wide variety of application requirements. It is also possible to use spotlights, linear lights or LED lights as lighting sources or lights for the lighting device according to the invention. Alternatively, all other lighting sources currently or in the future on the market can also be used in a lighting device according to the invention.

Further features and advantages of the present invention will become clear from the following description of preferred embodiments with reference to the accompanying drawings. 5

From Fig. 1 it can be seen that a lighting device according to the invention comprises two profile parts 1, 2 which extend in Fig. 1 into the plane of the drawing or out of the plane of the drawing in the longitudinal direction of the elongated lighting device. In the transverse direction of the lighting device, the profile parts 1, 2 are spaced apart from one another and are connected to one another by connecting means to be described in more detail below or can be connected to one another by the user on site at a suitable distance.

From Fig. 1, a lower cover 3 can be seen, which can serve as a connecting means in the illustrated embodiment. In Fig. 2a, the two profile parts 1, 2 are additionally connected by a

•••"I ⁵ i : : : 5 &Iacgr;

The suspension unit 4 arranged in the lighting device is connected to one another.

The profile parts 1, 2 can, for example, consist of an extruded aluminum profile. The cover 3 can also consist of extruded aluminum or of sheet metal. The cover 3 has alternating thickened and thinned sections 5, 6 in the transverse direction of the lamp. The sections 5, 6 can extend uniformly in the longitudinal direction of the lamp, so that a visually appealing impression of the lamp is obtained with corresponding longitudinally extending projecting and recessed areas of the cover 3.

· The thinned sections 6 are dimensioned in terms of their thickness in such a way that the user can separate the cover 3 in one of the thinned sections 6 on site in the longitudinal direction. In this way, the width of the cover 3 can be freely selected on site using simple means, for example by sawing or cutting. In this way, the distance between the two outer profile parts 1, 2 can also be adapted on site to the local conditions.

The sections 6 severed in the middle, for example, during such a separation process can, as can be clearly seen from Fig. 1, also serve as support sections 7, which can rest on shoulders 8 extending inwards on the underside of the profile parts 1, 2. The support sections 7 and the shoulders 8 can be secured to one another, for example, by means of screw connections or the like. Alternatively, the support sections 7 can also be placed loosely on the shoulders 8.

The suspension unit 4 shown in Fig. 2a has a central section 9, two lateral sections 10 extending obliquely downwards and to the side from the central section 9, and two lateral sections 10 which are connected to the outside of these lateral sections 10.

Sections 10 have adjoining outer sections 11 aligned parallel to the middle section 9. The outer sections 11 engage underneath a lower section 12 of a cable guide area 13 extending in the longitudinal direction of the profile parts 1, 2, which is aligned horizontally when the lighting device is in the position of use. The lower horizontal section 12 extends inwards from the profile part 1, 2. At the end of the horizontal section 12 facing away from the respective profile part 1, 2, there is an adjoining section 14 running diagonally upwards and inwards, under which, as can be seen from Fig. 2a, the lateral section 10 of the suspension unit 4 running diagonally downwards and outwards can rest. Between the lower section 12, the section 14 running diagonally upwards and inwards and the respective profile part 1, 2, the aforementioned cable guide area 13 is formed, through which cables for supplying lights as well as other cables to be specified in more detail below can be passed. Below the horizontally aligned section 12, a further projection 15 extending in the longitudinal direction of the profile parts 1, 2 is formed on the corresponding profile part 1, 2 at a distance from it. The projection 15 encloses a fastening groove 16 with the lower horizontal section 12 of the cable guide area 13, into which the outer section 11 of the suspension unit 4 projects in the embodiment shown in Fig. 2a.

It is possible to provide the user with the suspension unit 4 in different designs with regard to its width, so that the distance between the profile parts 1, 2 can be selected appropriately using suitably wide suspension units 4. It can be seen from Fig. 2c that the suspension unit 4 can simultaneously serve to connect different sections of the lighting device in the longitudinal direction. As an example, Fig. 2c shows profile parts 1, 1a and 2, 2a connected to one another by the suspension unit 4.

-12-

The profile parts 1, 1a, 2, 2a can each extend in lengths of, for example, 6 m. It is certainly possible to connect many of these, for example, 6 m long sections with one another by means of suspension units 4, so that, for example, elongated lighting devices are created which are 20 or 30 in long.

It is possible for the suspension unit 4 to be screwed to the profile parts 1, 2. For example, the downward and outward extending sections 10 of the suspension unit 4 can be screwed to the upward and inward extending sections 14 of the cable guide area 13. Alternatively or additionally, the outer sections 11 of the suspension unit 4 can be screwed to the lower horizontal sections 12 of the cable guide area 13.

Fig. 2b shows an alternative embodiment of a suspension unit 4, which has a middle section 9 and only two short outer sections 17, which extend only one or two centimeters diagonally outwards and downwards from the middle section 9. These sections 17 can, for example, rest from above on the section 14 of the cable guide area 13 that runs diagonally upwards and inwards. In this case, it is possible for the outer sections 17 to be screwed to the sections 14 that run diagonally upwards and inwards, for example.

The suspension means 18 shown in Fig. 2a, which can be designed as wires or ropes or the like, can be fastened in fastening openings 19 on the suspension unit 4. From Fig. 2c it can be seen that in the transverse direction of the lighting device, a whole series of fastening openings 19 are arranged next to one another on each of the two sides of the middle section 9 of the suspension unit 4. Furthermore, on the outside of this whole series of fastening openings

-13-

19 an insertion opening 20 is arranged through which, for example, a thickened end region of the suspension means ¹⁸ can be guided. All of the fastening openings 19 and the insertion openings 20 can be connected to one another by slots running in the transverse direction of the lamp. The user on site can thus carry out a balancing adjustment of the lamp device by selecting the fastening opening 19 through which the suspension means 18 is guided upwards out of the suspension unit 4. This can be particularly helpful in the case of sloping ceilings in a room.

From Fig. 1 it can be seen that the profile parts 1, 2 have further inwardly projecting projections 21 which extend in the longitudinal direction of the profile parts 1, - and which are spaced apart from one another in such a way that fastening grooves 22 are formed between them. Holding units 23, 24, 25, which can be seen in Fig. 3a, 3b and 3c, can be inserted into these fastening grooves 22. Installation means 26, for example, can be held on these holding units 23, 24, 25. The installation means 26 could, for example, be a ballast or a transformer for a lamp. The holding units 23, 24, 25 each have an outer edge which can be inserted into the fastening grooves 22. A middle section which can carry the installation means 26 is arranged between the outer edges. Depending on the embodiment of the holding units 23, 24, 25 shown in Fig. 3a, 3b and 3c, the middle section is at the same height as the outer sections or is arranged above or below these sections.

From Fig. 5b, a holding unit 27 can be seen, which essentially consists of a flat strip or a flat plate, for example made of sheet metal or aluminum. A lamp 28 is mounted on this holding unit 27, which has an arm projecting outwards beyond the upper limit of the corresponding profile part 1, 2, on which

-14-

For example, a light source can be arranged at the end.

Fig. 5a shows a further holding unit 30 which has a substantially U-shaped cross section. A lower U-leg 31 can extend into the fastening groove below the cable guide area 13. An upper U-leg 32 can extend outwards above the section 14 of the cable guide area which runs obliquely upwards and inwards as far as the profile part 2. In this case, a further upper projection 33 can be arranged on the profile part 2, on which the upper leg 32 of the holding unit 30 can rest. Furthermore, in the example shown in Fig. 5a, a light 28 with an outwardly extending arm 29 is attached to the upper leg 32 of the holding unit 30.

Fig. 4 shows a lighting device according to the invention in which the lower cover 3 is at least partially removed. Instead of the cover 3, a linear light 34 rests on the inwardly extending shoulders 8 of the profile parts 1, 2, which is only shown schematically in the embodiment shown.

Fig. 6 shows a further holding unit 35, on the underside of which a light 36 is suspended, which can hang downwards from the lighting device, for example in an area in which the cover is removed. The holding unit 35 is designed, for example, as a web-shaped, tubular or plate-shaped holding means and has engagement parts 37 on its end sides facing the profile parts 1, 2, which can engage in corresponding fastening grooves 22.

As can be seen from Fig. 1, recesses 38 are formed on the profile parts 1, 2, which also extend in the longitudinal direction of the profile parts 1, 2

Other different designs are certainly possible according to the invention.

A large number of lights or light parts and a large number of other installation elements can be attached to the lighting device according to the invention. Lights in particular include spotlights, linear lights or LED lights. Other installation elements that can be mentioned are loudspeakers, microphones, sockets, motion detectors, surveillance cameras, emergency and information lights, smoke or gas detectors and the like. Ultimately, all lighting technology, security technology or surveillance technology products known today or in the future can be combined with a lighting device according to the invention. For example, the aforementioned lights or installation elements can be attached to the cover 3. Alternatively or additionally, lights or installation elements can be attached to the inside or outside of the profile parts 1, 2, for example with the aid of holding units that are inserted into fastening grooves 16, 22. Furthermore, it is also possible, for example, to arrange optical fibers in the lighting device, whereby the light guided therein can be guided out of the lighting device in a targeted manner over its entire length or locally.

It is possible to run any supply cables for lights or for the power supply through the cable routing area. It is also possible to run cables for the aforementioned installation elements, for example for smoke detectors or surveillance cameras, through the cable routing area 13. It is also possible to run telephone cables or computer cables or the like through the cable routing area 13. The cable routing area 13 can be divided into two or more areas by installing appropriate partition walls.
