Abstract

The invention concerns a light fixture which has a linear lighting field, is suitable for forming lighting trunking and is reduced to the parts essential for its operation, the light fixture housing consisting directly of an integral reflector arrangement (1) which is designed mirror-symmetrically relative to a vertical light fixture centre plane containing the light fixture longitudinal axis. The reflector arrangement consists of a thin-walled material whose surface, at least in partial regions, is finely structured by surface deformation in reinforcing manner. The reflector arrangement further comprises, remote from its light-outlet opening (2), a pair of outwardly projecting, mutually parallel legs (14) for accommodating electrical and/or mechanical light fixture components. Connection elements for a trunk arrangement of the light fixture are formed either by end wall parts (3) of the light fixture itself or individual elements (8). To that end, the end wall parts comprise on an inner side facing the reflector arrangement (1) an insert groove (33) matching their profile. Provided on its outer side is a tongue-and-groove profile (35, 36) via which the end wall parts (3) can be inserted one into the other at the ends, in pairs and flush so that their contours match. Further structural elements (for example, 7, 7', 8 and 94) and luminous components (for example, 91 to 93) complete the light fixture structure to form a lighting system.

Continuous-field luminaire capable of continuous lighting

The invention relates to a strip light capable of linear lighting with a trough-shaped lamp housing which can be attached via a pendulum and / or directly to a ceiling, on the end walls of which connecting elements are provided for optional direct lighting of individual linear lights to form a light strip.

Lighting devices for large-scale rooms are often implemented in the form of continuous-row lighting systems, in which a plurality of luminaires, often placed directly next to one another, form a linear, seemingly closed lighting system. Such light strips are also arranged in large areas, such as assembly, production or storage halls, but also sports facilities, also in a plurality of rows parallel to one another, preferably in the longitudinal direction of such a room.

From EP-B1-0 486 714, for example, trunking systems of the type mentioned are known. The supporting structural element in such a continuous row system is a mounting rail of a length that can accommodate several luminaire inserts. Through-wiring is usually provided in the mounting rail for the electrical supply of the light sources. In many cases, the luminaire inserts have a base body with an essentially flat support plate, which is attached to the mounting rail when the light strip is installed and is fixed to it by means of rotary locks. The support plate serves as a receptacle for all electrical, including mechanical elements of a luminaire. All of these elements, with the exception of lamp sockets, are preferably preassembled on the upper side of the support plate and arranged in such a way that they immerse in the cross section of the support rail when the luminaire insert is installed. In many known trunking systems, a luminaire reflector is then individually attached to this support plate of a luminaire insert, to releasably attach a luminaire housing with grid or a luminaire cover. The same rotary fasteners are often used for fastening, with which the support plate itself is to be fixed on the mounting rail.

Due to its modularity, this known structure of continuous-row lighting systems enables extraordinary flexibility in the arrangement and selection of luminaires, so that individual lighting tasks can be solved in different ways with such continuous-row lighting systems. In addition, because of their modular structure, such trunking systems also meet changing requirements for room lighting, e.g. B. can be easily adapted for a different use of space. A disadvantage of this basic structure of known light band systems with a large number of individual components is the relatively high outlay due to the modularity desired per se, which is reflected in the tool, production and storage costs.

As is apparent from DE-Cl-43 42 657, this disadvantage has already been recognized. From this, a luminaire unit for continuous row systems is known, the special feature of which is that there is no longer a lamp, in particular in the form of one or more fluorescent lamps arranged in a luminaire unit, fixed to the support plate of the luminaire insert but via lamp holders directly to the mounting rail of the continuous row system. In this known luminaire unit for a continuous-row lighting system, a support plate inserted into the opening of the mounting rail is therefore dispensed with, thus saving it. Instead, the reflector unit of the luminaire insert serves directly as a cover for the mounting rail which is open in the direction of the illuminated surface. In order to be able to implement this simplification of the construction of a luminaire unit for a continuous row system, all mechanical and electrical components of a luminaire including the sockets for the illuminant (s) are placed directly in the free cross cut the mounting rail used and fixed there. The reflector arrangement with which the mounting rail is covered on its surface directed into the room must then be designed in such a way that the sockets fastened to the mounting rail can be pushed through the reflector arrangement or that corresponding cutouts on their front edges for receiving the sockets are provided.

With this known solution, a certain disadvantage with regard to assembly and ease of maintenance has to be accepted in order to achieve a simpler and therefore less expensive luminaire construction. Viewed from this point of view of cost-effectiveness, however, the known solution cannot yet be completely satisfactory because the elimination of only one support plate means a relatively small reduction in costs in comparison to the disadvantages of a smaller range of variations that are accepted in this way.

Furthermore, light strip-capable lights with a trough-shaped light housing, which can be attached via a pendulum or directly to a ceiling, are known, which have front-side housing wall parts which can be put together directly to form a light strip. These luminaires do not use a mounting rail; instead, the housings of the individual luminaires are suitably stable and designed so that, in addition to the illuminants and the reflector arrangement surrounding them, they also accommodate the electrical and mechanical components, as well as through-wiring if used in a Allow band arrangement.

US-A-3 599 911 describes an example of such a light band-capable lamp. In this case, end wall parts of the lamp housing are designed as stamped sheet metal parts with angled edges, by means of which they are fastened to the lamp housing by means of screws or rivets. In order to be able to anchor the end wall parts to one another, they have mutually arranged hooks and eyes. For joining forehead wall parts, they must first be placed next to each other in the transverse direction so that the hooks can be inserted into the corresponding eyelets. A transverse movement of the assembled end wall parts is then required to lock the hooks. The assembly process for a light strip is therefore relatively complex and requires an additional adjustment in order to achieve an exact alignment of the assembled lights.

Also known from EP-B-0 264 857 is a strip light capable of linear lighting, in which end plates are provided as adapter elements on the end walls of the light housing, the outer sides of which, in the manner of stackable elements, each have plug-in frames which can be inserted into one another. This way, linear luminaires can be aligned by simply plugging the outer sides of these end plates together. However, an additional end cap is then required for the end of a single lamp or the end of a light strip.

The object of the present invention is to create a further embodiment for a light strip capable light of the type mentioned in the preamble of claim 1, which can be produced particularly cost-effectively in the restriction to purely functional features, but which offers contemporary lighting technology in an appealing light design and at the same time is simple and easy for the fitter to use without tools, possibly also in a belt arrangement.

In the case of a light band-compatible lamp of the type mentioned above, this object is achieved according to the invention by the features described in the characterizing part of patent claim 1.

In comparison to the relatively complex known known solutions for continuous-row lighting systems with luminaire units that can be inserted in mounting rails, this inventive solution the great advantage of a particularly simple construction. It can be used both as a single luminaire and in a continuous row without the need for additional components for the continuous row installation. It offers the advantage of the rail systems of a ceiling-side arrangement of the electrical and mechanical components of a luminaire with simple through-wiring in a continuous row arrangement. In terms of its construction concept, it is particularly simple compared to conventional continuous row luminaires. A mounting rail as in known ceiling / rail systems is not required even with a hinge arrangement. In the case of conventional light band-compatible lights, which are implemented without their own mounting rail, a stable light housing is usually used to ensure the stability of the light or the light line arrangement and to accommodate the electrical and mechanical components. This is also not provided in the luminaire structure according to the invention. These constructive functions are also taken over by the design of the reflector arrangement. This is possible because the web-shaped material from which the reflector arrangement is made is stiffened, for example by surface deformation. A method known from international patent application WO 94/22612 is particularly advantageous for this surface treatment. The reflector arrangement can thus also be produced inexpensively in terms of production technology using known tools. It is therefore not just a technical lighting element but also a structural part that takes the place of its own luminaire housing.

It is particularly advantageous not only to combine the reflector arrangement and the mounting rail to form a single unit, but rather to produce these lighting parts directly in one piece from a thin-walled flat material by appropriate deformation. In terms of production technology, such a solution can be implemented easily and therefore also cost-effectively using roll-forming systems customary in lighting technology. The Possibility to use this lamp not only as a single lamp but also in a continuous row arrangement is given by appropriate sti wall parts that can be inserted into each other on the envelope. This enables tool-free assembly of the hinge without the need for additional connecting elements in this case.

Now the linear luminaire according to the invention should e.g. can also be used in the renovation of existing lighting systems to open up further application options for this solution. According to a second exemplary embodiment of a linear luminaire capable of continuous row lighting with a trough-shaped luminaire housing which can be attached via a pendulum and / or directly to a ceiling, on the end walls of which connecting elements are provided for optionally direct stringing together of individual linear luminaires to form a continuous row, this has

- A one-piece reflector arrangement that directly forms the luminaire housing and is mirror-symmetrically configured with respect to a vertical luminaire center plane that contains the longitudinal axis of the luminaire, and is made of a thin-walled, web-shaped, reflecting material, the surface of which is stiffened, at least in some areas, by surface deformation, and that of its light exit opening facing away, has a pair of outwardly projecting, spaced apart legs for receiving electrical and / or mechanical lamp components,

- Furthermore, one-piece end wall parts, one of which faces the inside of the reflector arrangement

Have profile corresponding slot and

- Furthermore, mounting brackets, which have a pair of fingers, which include pliers from the side of the legs of the reflector arrangement, the side faces thereof and form a receptacle for lamp holders for rope or pendulum suspension or are used directly for ceiling mounting of the lamp. In contrast to the embodiment described above, in this solution form with an unchanged construction concept and appearance, individual fastening brackets are used, which can be mounted essentially anywhere along the length of the lamp. This is particularly advantageous when refurbishing old lighting equipment because existing ceiling fixings of the lamp (s) can continue to be used. Incidentally, this supplement for a light band capable according to the invention

Langfeldleuchte an alternative specified that fulfills the idea of a versatile product family, as further developments of both embodiments show, which are described in the dependent claims.

Embodiments of the invention are explained in more detail below with reference to the drawing. It shows:

FIG. 10 shows an embodiment of the lamp in which the light exit opening is covered by a grid,

Figure 11 shows an embodiment of the lamp with a channel mirror covering a light source in the direction of the light exit opening of the lamp and

Figure 12 shows a further embodiment of the lamp, in which a cover of the instead of such a channel mirror

Light exit opening is provided by means of a prismatic lens.

In the exemplary embodiment of a light-band-compatible luminaire shown in FIG. 1, a reflector arrangement 1 is mirror-symmetrical to a vertical central plane containing the luminaire's longitudinal axis. It is shown by way of example that side surfaces 11 and 12 of the reflector arrangement 1 are composed of flat partial surfaces, but these side surfaces 11 and 12 could also be formed as conical sections or composed of such surfaces. This means that, in the present case, it is left to the person skilled in the art which profile design he chooses for these side surfaces 11 and 12 for reasons of lighting technology.

An advantageous embodiment of the reflector arrangement 1 consists in providing it with a small-area surface structure at least in partial areas, but possibly also completely. Methods for surface processing of sheet-like material are available today for this purpose, which enable the material to be substantially stiffened at low cost. In terms of lighting technology, this means that the surfaces, for example the side surfaces 11 or 12 of the reflector arrangement 1, preferably reflect light emitted by a lamp arranged in their interior. With this reflector design, a certain comparison is _ß FINISH to reach the light emitted from the lamp light output within its spatial distribution. Mechanically, the structuring of the surface of the reflector arrangement 1 has the further advantage that its rigidity can be increased significantly in comparison to a non-structured, smooth surface. Such a structuring thus also contributes to a considerable extent to the transverse stability of the lamp, so that in this case the material thickness of the reflector arrangement 1 can be chosen to be correspondingly thinner without loss of stability.

The reflector arrangement 1 has a pair of projecting legs 14 in the region of a top surface 13, which lies opposite the light exit opening 2, and which are arranged symmetrically in a mirror image at a predetermined distance from one another to the vertical center plane of the lamp. These legs 14 are each formed by double folding the sheet-shaped, thin-walled material of the reflector arrangement 1, this material preferably being selected from one of the usual reflector materials for luminaires. The two legs 14 thus, together with the top surface 13 of the reflector arrangement 1, form a channel which is closed on three sides and is essentially U-shaped, the longitudinal axis of which lies in the central plane of the lamp and which is open at the top facing away from the light exit opening 2. The interior of this channel is intended to accommodate electrical and mechanical components of the lamp, for example an electronic ballast as an operating device for the lamp (s) of the lamp for lamp sockets inserted through the cover surface 13 and a lamp wiring. For reasons of clarity, these details are not shown in FIG. 1, since the person skilled in the art has constructive solutions for this, e.g. B. are also known from the ceiling / rail systems discussed in the introduction.

In the embodiment shown in Figure 1, end caps are on the end faces of the reflector assembly 1 as _S tirnwandteile 3 constructively designed so that the luminaire is capable _l maybe ribbon. Viewed in cross-sectional profile, the sti wall parts 3 have a central region 31, which closes off the channel formed by the legs 14 of the reflector arrangement 1 and tapers downward in the direction of the light exit opening 2 of the lamp in an approximately triangular manner and thereby covers a lamp holder which cannot be seen in FIG. 1. Following the cross-sectional contour of the reflector arrangement 1, fingers 32 pointing laterally outwards are attached to this central region 31.

FIGS. 2 to 4 each show a view of the outside or inside and a top view of the end wall part 3 to clarify details on a somewhat larger scale. Following the outer contour close to the edge, a narrow insertion groove 33 is provided on the inside of the end wall part 3 shown in FIG. 3 for receiving the end profile of the reflector arrangement 1. Because of the approximately true-to-scale representation of the end wall part 3, this groove 33 can only be seen in FIG. 3 as a somewhat thicker line. When assembling the lamp, the front edge of the reflector assembly 1 is inserted into this slot 33 and locked there. A number of possibilities are available to the person skilled in the art as latching means, for example in the form of end-to-end slots in the reflector arrangement 1, which correspond to corresponding latching lugs in the end wall part 3, so that no further explanation is required and a detailed representation in the drawing is dispensed with. Furthermore, the inside of the end wall part 3 has in its upper edge area a circular segment-shaped recess 34, the meaning of which as a receptacle for a lamp holder will still be explained.

In Figure 2 and in particular Figure 4 it can also be seen that on the outside of the central region 31 of the end wall part 3, running parallel to the lamp center plane, a tongue and groove profile consisting of a plurality of mutually successive grooves 35 or springs 36 is provided. This profile has a defined pitch, ie the grooves 35 and tongues 36 have approximately the same width and also the same depth. In the overall impression of the representations in FIGS. 1 and 2, this useful

/ Spring profile 35, 36 completely uniform, so that the outside of the end wall part 3 appears closed. On closer inspection, in particular with reference to FIG. 4, however, an asymmetrical offset to the light center plane becomes clear, since the tongue and groove profile on the left edge of the central region 31 with a tongue 36, while it terminates on the right edge with an edge groove 35.

5 shows the reason for this asymmetrical arrangement of the tongue and groove profile 35, 36 of the central region. In this illustration, two of the identically designed Sti wall parts 3 are juxtaposed, from this it is clear that the tongue and groove profiles 35, 36 of two end wall parts 3 to be placed one against the other, inserted into one another, enable the contours of the end wall parts 3 to be joined together with the same contours without it being about alignment is required.

In this exemplary embodiment, the recess 34 shown in FIG. 3 in the form of a blind hole cut in the form of a circular segment is intended to receive a lamp holder 4 which forms the lamp-side end piece of a lamp suspension. In this embodiment, this is designed as a circular disk which can be inserted into the end wall part 3 from the inside. In Figures 1 and 2, the lamp suspension as a wire-shaped pendulum 5 is shown as an example. The disc-shaped design of the lamp holder 4 allows its relative position to the end wall part 3 to be adjusted approximately in an angular range α - see FIG. 2. In the operating position, a position pivoted out of the vertical position can therefore be selected for the luminaire within this range, provided that this is desired for the desired room lighting in individual cases. In Fi Gur 2 is further indicated schematically that the relative position of the lamp holder 4 to the end wall part 3 is fixed by means of a grub screw 6. This is also only to be understood as an example, because it would also be easily conceivable to form-fit the connection between the lamp holder 4 and the end wall part 3, for example by means of a toothing.

1 and 2 finally show that 4 notches 41 are provided in the edge surface of the lamp holder 3 protruding from the end wall part 3. In the case of a light band arrangement of the luminaire, these serve as receptacles for through-wiring from luminaire to luminaire, which can thus also be fixed.

6 and 7 show a further embodiment of the lamp in profile or in a section of a side view. In a modification of the embodiment described above, individual mounting brackets 7 are provided as the lamp holder for a cable or pendulum suspension of the lamp. Each mounting bracket has one

Cover surface 71 and two fingers 72 projecting laterally from this cover surface 71, into which an internal slot 73 is let near their outer ends. The profile of the fingers 72 is adapted to the profile of the reflector arrangement 1, so that the fastening bracket 7 can be slipped over the outside of the reflector arrangement 1. In this exemplary embodiment, the outer ends of the side surfaces 11, 12 of the reflector arrangement 1 are flanged outwards and thus form lateral latching edges 15. Furthermore, the fastening brackets 7 are designed as a sheet metal part, in which the cover surface 71 consists of two sides of the profile of FIG. 72 surface elements that are folded at right angles.

When mounting the mounting bracket 7, the locking edges 15 of the reflector arrangement 1 snap into the respectively assigned slot 73 of the mounting bracket 7. They are held in this position by a locking projection 74 which the outer ends of the fingers 72 is arranged on the inside thereof and a bottom surface of the slot 73 projects slightly beyond ^¬ . The top surface 71 of the mounting bracket 7 now serves in a manner known per se to accommodate a cable or pendulum suspension of the lamp. In the illustration selected in FIGS. 6 and 7, a rope hanger 75 is provided as an example, in which a light-side end of a rope, which is no longer shown, can be displaceably fixed for ceiling compensation. It is well understandable for the person skilled in the art that the cover surface 71 of the fastening bracket 7 itself can also be easily and directly fixed to a room ceiling by means of a screw connection, so that no further example is required.

FIG. 8 shows a further embodiment of the mounting bracket 7 described above. In this configuration of the mounting bracket 1 ', the space enclosed by the top surface 71 and the adjacent foot ends of the fingers 72 from three sides is designed in such a way that it has a mounting rail 77 in profile of one of the known ceiling and rail systems for light band arrangements includes. With this embodiment of the mounting bracket 7 'shown in FIG. 8, which has the same function as that of the mounting bracket 7 described with reference to FIG. 6, it is possible to use the luminaire described here also for renovations of ceiling and rail systems in which as usual, a mounting rail 8 is used as the supporting element. Furthermore, FIG. 7 schematically shows a detail of an electronic ballast 76 as operating means for the lamp described, which is placed on the top surface 13 of the reflector arrangement 1 between its two legs 14.

FIG. 9 shows a further embodiment of the luminaire, in which, in a modification of the embodiment described in particular with reference to FIGS. 4 and 5, it is not the end wall parts 3 themselves are used to connect two or more individual lights to form a light band. Instead, an individual connecting element 8 is used to implement this function. This essentially consists of two brackets 81 and 82, which are fixed to one another by a screw connection 83, 84, 85. Each of the two brackets 81 and 82 of the connecting element 8 has legs which are bent in a U-shaped manner on the side from a plate which serves to hold the screw connection 83 to 85. In the case of one bracket 81, the clear width between its legs is selected such that it can be inserted into the profile of the doubly bent legs 14 of the reflector arrangement 1. In a mirror-symmetrical arrangement for this purpose, the second bracket 82 is inserted with the ends of its legs sitting on the top surface 13 of the reflector arrangement 1 between the two legs 14 of the reflector arrangement 1. Thus, one clamp 81 of the connecting element 8 engages the top surface 13 of the reflector arrangement 1 from below, while the other clamp 82, guided on the inner sides of the legs 14 of the reflector arrangement 1, rests on the top surface 13 thereof. The screw connection between the two brackets 81 and 82 now forms a connecting screw 83, a toothed washer 84 placed thereon and a locking washer 85. The connecting screw 83 inserted together with the toothed washer 84 via a hole (not shown) in the one bracket 81 of the connecting element 8 is there by means of the locking washer 85 held captive. If the connecting screw 83 is screwed into a threaded hole, also not shown, in the plate of the other bracket 82, the two brackets 81 and 82 of the connecting element 8 are braced on the reflector arrangement 1 from two sides, in particular the top surface 13 thereof.

If the connecting element 8 in each case overlaps the end region of two lamps placed directly on the end face and in the manner described in each Bolted forehead area, the two lights are non-positively fixed to each other. In particular the two abutted lamps are thus aligned in its longitudinal axis without adjustment because a bracket 81 angle of the connecting element 8 in its internal cross-section of the 's ^¬ 14 of the Re lecturer arrangement is performed 1 and the other clamp 82 with its slightly outwardly splayed legs acts on the bending edges between the top surface of the reflector arrangement 1 and its legs 14.

The embodiment described above with reference to FIG. 8 for the connection of two luminaires placed next to one another to form a light band is to be used advantageously instead of the first embodiment described with reference to FIGS. 1 to 5 if longer light bands are to be formed in this way and in an application case in a rougher one Operating environment a structurally particularly safe luminaire connection appears necessary.

With regard to lighting technology, it should be added that the above-described embodiments of the luminaire can of course be supplemented by additional accessories in order to realize light distributions adapted to an application. Thus, if desired, the reflector arrangement 1 can be designed so that it is partially transparent, so that part of the light emitted by a lamp inside the reflector arrangement 1 passes through it and thus serves as secondary light, for example for illuminating the ceiling.

As shown schematically in FIG. 10, a grid for cross-glare control can be provided in the light exit opening 2 of the lamp. As in the embodiment described with reference to FIG. 6, in this case the outer edges of the side faces which are flanged outwards at the side

11, 12 of the reflector arrangement 1 can be used to insert such a grid into the light exit opening 2 of the lamp. snap and lock on the reflector assembly 1.

A further embodiment of the lamp is shown schematically in cross section in FIG. 11 for further supplementation. In this case, a lamp, preferably a rod-shaped fluorescent lamp 9, is also inserted into the reflector arrangement 1. In the direction of the light exit opening 2 of the lamp, a channel mirror 92 is provided beneath the lamp 9, partially coaxially surrounding it, extending in the direction of the longitudinal axis of the lamp and thus aligned parallel to the lamp 9. This channel mirror 92, which is fixed on the lamp 9 in the exemplary embodiment, reflects light emitted by the lamp 9 directly in the direction of the light exit opening 2 of the lamp against the reflector arrangement 1 and thus acts as a diffuser and as a shading element for the lamp 9.

In FIG. 12, another option for glare control of the lamp is shown schematically for rounding off. In this

The light exit opening 2 of the lamp is covered by a prismatic lens 93. Similar to the channel mirror 91 in FIG. 9, the light emitted by the lamp 9 directly in the direction of the light exit opening 2 of the lamp results in a light distribution which reduces the high luminance differences occurring locally in the light exit opening 2 of the lamp. In this case too, longitudinal edges of the prismatic lens 93 can be held in a holder 94, which is shaped analogously to the design of the outer ends of the fingers 72 of the mounting bracket 7 according to FIG. 6, so that a tongue and groove connection between the prismatic lens 93 and the reflector arrangement 1 enables a snap connection between these two lamp elements.

The embodiments described above with reference to the drawing show that building on a common system stem concept with a few, especially inexpensive luminaire components, a luminaire family can be realized which, with a uniform appearance, can be used both for the redesign and / or for the refurbishment of lighting systems. In addition to the described embodiments, further options are available to the person skilled in the art to adapt the luminaire design to the framework conditions of the application in a further development of the system concept. For example, in order to achieve the desired light distribution characteristics of the luminaire, he can adapt the profile of the reflector arrangement and / or change the position of the lamps used as light sources in relation to the reflector arrangement.
