Abstract

Disclosed is a luminaire for illuminating rooms, comprising a base module and a cover/reflector module (10, 20, 30, 40) that can be fastened thereto. The base module consists of an elongate support element (1), at least the bottom side of which supports sockets for a lamp (3) supplying direct light and an operating device (3) for triggering and operating the lamp. The cover/reflector module (10, 20, 30, 40) that can be fixed to the base module is provided with direct reflector walls (13) for the lamp (3) and side walls (11, 21, 31, 41) which are preferably connected thereto in an integral manner and extend upwards so as to laterally cover the base module such that the esthetic impression is determined exclusively by the cover/reflector module (10, 20, 30, 40).

Description

Luminaire with lamination / reflector module

The present invention relates to a luminaire for room lighting, the appearance of which can be changed in a simple manner.

Luminaires for room lighting are known in a wide variety of configurations. DE 196 20 209 AI of the applicant describes, for example, a lamp which has a triangularly profiled base body as a carrier element, in which the operating devices for operating the lamps are arranged. A first lamp is arranged below the base body and is intended for direct room lighting, i.e. the light emitted by this lamp essentially hits the area to be illuminated directly. In order to avoid glare effects, the lamp is surrounded by a luminaire grid which has two direct reflector walls and a large number of transverse lamellae extending transversely thereto. The grid serves to restrict the light emitted by the lamp to a predetermined angular range.

In addition to the lamp for direct lighting, another lamp is arranged on the top of the base support, which illuminates the ceiling to which the lamp is attached and thus serves to indirectly illuminate the room. As a rule, it is possible to control the lower lamp for direct lighting and the upper ¹ lamp for indirect lighting separately and thus individually adjust the proportion of direct or indirect light.

In this known luminaire, further elements determining the overall impression of the luminaire, such as, for example, wings or additional indirect reflectors, can be arranged on the side of the base body. In principle, however, the triangular base body or its two side surfaces are visible from the outside, so that the aesthetic impression caused by the side surfaces does not change, regardless of the additional attachment elements.

The present invention has for its object to provide the ability to easily give a light of the type described above a new look.

The object is achieved by a lamp which has the features of claim 1. The luminaire basically consists of a base module and a so-called lamination / reflector module. The base module has an elongated support element which, at least on its underside, holds sockets for one Direct lighting provided lamp as well as an operating device - such as an electronic standard switching device - for driving and operating the lamp. The lamination / reflector module, which has direct reflector walls for the lamp, and side walls connected to the latter can be attached to the base module, the side walls being extended upwards in order to cover or conceal the base module laterally.

According to the present invention, the aesthetic impression of the lamp is thus determined exclusively by the side cover of the lamination / reflector module, since neither the carrier element nor the operating device arranged therein is visible to the lamp.

When the luminaire is finally assembled, there are essentially two modules. On the one hand, the basic module with the support element and the control gear, and on the other hand, the lamination / reflector module, which determines the aesthetic impression of the lamp. The complete luminaire is then simply obtained by attaching the lamination / reflector module to the pre-assembled base module. In this way, it advantageously results that, using a standardized base module, different aesthetic luminaire designs can be achieved in a simple manner by mounting correspondingly designed lamination / reflector modules. Preferably, the lamination / reflector module is simply snapped into place with the support element, so that the lamination / reflector modules Austausch can be exchanged in a simple and quick manner and the lamp can thus be given a new look.

Further training is the subject of the subclaims.

Thus, the carrier element of the base module preferably has further sockets on its upper side for a further lamp provided for indirect lighting and a second operating device required to operate this further lamp. In order to achieve as constant as possible lighting properties for the luminaire in spite of everything, the second lamp for the indirect lighting is then preferably assigned its own indirect reflector, which is also attached to the carrier element. The light output of the second lamp is determined exclusively by the indirect reflector, so that the function of an indirect reflector is actually present, regardless of the forms of the laminating / reflector module that are often predetermined from an aesthetic point of view. However, this indirect reflector is still covered laterally by the raised side walls of the lamination / reflector module and is not visible. According to an advantageous embodiment of the invention, the side walls of the lamination / reflector module are integrally connected to the direct reflector walls, as a result of which a particularly inexpensive but stable embodiment is obtained. As an alternative, however, there is also the possibility of fastening the side walls to the direct reflector walls by clamping. In the case of an integral connection, the direct reflector walls preferably merge in one piece on their undersides into the side walls of the lamination / reflector module, so that the lower region of this module is double-walled. Cross slats then extend between the direct reflector walls, each of which is attached to the direct reflector walls with their end faces, preferably locked in place with them. The advantage of this double-walled design of the lamination / reflector module is that its side walls form a smooth or closed surface, without the elements for fastening the transverse slats on the direct reflector walls being visible from the outside.

The invention also relates to a method for producing a luminaire, a first step being to provide a prefabricated base module which consists of an elongated support element which, at least on its underside, has sockets for a lamp provided for direct lighting and an operating device for actuation and operation the lamp carries, and a lamination / reflector module is attached to the prefabricated base module, which has direct reflector walls for the lamp and side walls connected to it, with the side walls being extended upwards to cover the side module of the base module. By providing several lamination / reflector modules with different shapes, luminaires with a different aesthetic impression can be obtained in a simple and cost-effective manner.

The invention will be explained in more detail below with reference to the accompanying drawing. Show it:

1 shows the principle of the lamp according to the invention consisting of a standardized base module and optionally mountable lamination / reflector modules;

Figure 2 shows a lamp with a first lamination / reflector module in section.

Fig. 3 shows a variant of the lamp shown in Fig. 2; and Fig. 4 to 7 further embodiments of the lamp with different lamination / reflector modules.

Fig. 1 shows the principle of the present invention. This consists in the fact that the luminaire essentially consists of a standardized and preassembled base module as well as a lamination / reflector module to be attached to the base module. The essential element of the base module is an elongated support element 1, which initially contains the operating devices for the lamps. These can consist, for example, of electronic ballasts 2 for controlling the lamps. In the example shown, the light from the luminaire is generated on the one hand by a first lamp 3 which is arranged on the underside of the carrier element 1 and is provided for direct lighting. In order to avoid glare effects from the light emitted by this first lamp 3, this is assigned a grid which is part of the lamination / reflector module described in more detail later.

A second lamp 4, which is provided for indirect lighting, can also be arranged on the upper side of the carrier element 1. With the aid of a cup-shaped indirect reflector 5 surrounding the second lamp 4, the light from this lamp 4 is radiated onto the ceiling of the room to be illuminated. The two lamps 3 and 4 are elongated gas discharge lamps, preferably fluorescent lamps, which are controlled via the electronic ballasts 2 arranged in the carrier element 1. It is possible to individually adjust the brightness of lamps 3 and 4 and thus to vary the ratio of direct to indirect lighting. Instead of a single lamp, depending on the field of application, it can also be provided to arrange a plurality of lamps on the top and / or bottom of the carrier element 1.

Fastening elements (not shown) are also arranged on the carrier element 1, by means of which the carrier element 1 and thus ultimately the entire lamp can be fastened to the ceiling of a room. Furthermore, there are latching projections 6 on both sides in the lower region of the carrier element 1, which allow simple attachment of the lamination / reflector modules to the carrier element 1 by means of latching.

The outer shape of the lamp is determined by a lamination / reflector module which is attached to the carrier element 1. In Fig. 1 three differently designed lamination / reflector modules 10, 20, 30 are shown, each giving the lamp a completely different appearance. It is essential that the side walls 11, 21, 31 of the lamination / reflector modules 10, 20, 30 are so high that they completely cover the carrier element 1 and the second lamp 4 arranged on its upper side and the indirect reflector 5 laterally in the assembled state. Accordingly, only the lamination / reflector module 10, 20, 30 is visible from the outside. Since this can largely be designed freely in its forms, luminaires with very different looks can be obtained in a simple manner.

In order to maintain the most uniform lighting properties in spite of everything, the indirect reflector 5 is already an integral part of the standardized base module and is also attached to the carrier element 1. The upward light emission of the second lamp 4 is therefore determined independently of the shape of the lamination / reflector module 10, 20, 30 exclusively by the indirect reflector 5.

2 shows the luminaire according to the invention with the first lamination / reflector module 10 attached to it. As can be seen from this sectional view, the lamination / reflector module 10 forms a luminaire grid in its lower region 12 surrounding the lower lamp 3, which consists of two direct Reflector walls 13 and transverse lamellae 15 arranged transversely thereto. The transverse fins 15 are locked with their end areas with the two direct reflector walls 13.

The lamination / reflector module 10 shown in FIG. 2 is advantageously characterized by the one-piece design of the two side regions. These consist of a single sheet metal part which has been bent into the V-shaped structure shown, so that the direct reflector walls 13 each merge integrally into the side walls 11 on their undersides. A cavity 14 is thus formed between a direct reflector wall 13 and a side wall 11, into which the fastening tabs 16 arranged on the end faces of the transverse slats 15 engage. Due to this double-walled design, the fastening tabs 16 of the transverse slats 15 are not visible from the outside. Instead, the side walls 11 form a closed surface. In comparison to the direct reflector walls 13, the side walls are laterally drawn further upward, so that they completely cover both the carrier element 1 and the indirect reflector 5 with the upper lamp 4 arranged therein.

From the outside, only the two side walls 11 of the lamination / reflector module 10 are therefore visible. These can now be designed accordingly to give the lamp a desired shape. In the example shown in FIG. 2, the side walls 11 are initially drawn inward in an arc shape and led out again in the upper area. As a result, they form the shape of two pot-like reflectors attached to one another on their head sides.

The lamination / reflector module 10 is fastened to the carrier element 1 with the aid of latching elements 17 which are arranged on the upper sides of the direct reflector walls 13 and cooperate with the projections 6 on the carrier element 1. The lamination / reflector module 10 can thus be snapped onto the carrier element 1, which furthermore also allows the lamination / reflector module 10 to be easily replaced in order to give the lamp a new shape.

As shown in Fig. 3, it is also possible to dispense with the upper lamp for indirect lighting and instead to fix the lamp directly to a ceiling of a room to be illuminated. In this case too, the base module is covered laterally by the lamination / reflector module, so that, as before, only the shape of the lamination / reflector module determines the aesthetic impression of the luminaire. The area originally provided for the indirect reflector above the carrier element 1 can then be used, for example, as a cable space for the passage of lines.

4 - 6, in which the same elements are provided with the same reference numerals, 'show further design options for the lamination / reflector module. As can be seen from the illustrations, the different lamination / reflector modules 20, 30, 40 differ only in the design of the side walls 11. The shape of the direct reflector walls 13 for the grid, however, is identical. This ensures that, despite the different shapes of the lamination / reflector module, the lighting properties of the luminaire for direct lighting remain unchanged. In these configurations, too, it is possible to dispense with the upper lamp for indirect lighting, as shown in FIG. 7.

The present invention thus opens up the possibility of simply giving a lamp a new look. Thanks to the modular concept with a standardized base module, which contains the operating devices for the lamps and the lamps, and the lamination / reflector module that can be attached to them, even the most varied shapes can be made available at low cost.
