Description

The invention relates to a lighting system according to 1

the preamble of claim 1. ;'

"The lighting in sales and exhibition rooms, but also increasingly in living areas, is becoming increasingly demanding. Particularly undesirable is the lighting installed on the ceiling.

Ii type of lighting or* arrangement of lights. The f

Desire for the simplest possible variation of the spatial k

I Arrangement of the lighting fixtures plays an important role.

If the arrangement of the lights cannot be precisely determined in advance or the lighting requirements change frequently (as in sales and exhibition rooms), power rails have previously been installed in the ceiling and/or wall. Adapters are used to connect and attach lights in different places. The power rails are installed in a predetermined grid, e.g. on the ceiling. It is also possible to use the power rails as supports for suspended ceiling panels. The disadvantage here is that you are limited to the grid of the power rails and only the lighting fixtures can be arranged variably along the power rails, i.e. one-dimensionally. The lighting fixtures are attached using screws or plug connections. The change in the price of the lights can therefore only be adjusted over time and with structural consideration.

effort, while a subsequent change to the current line grid is practically impossible.

The invention is therefore based on the object of designing a lighting system of the type mentioned at the beginning in such a way that it is easy to install and can be easily adapted to the most diverse spatial conditions.

The invention solves this problem with the help of the features of claim 1. Further advantageous embodiments of the invention are the subject of the subclaims.

By using magnetic conductor elements as supports for the lighting fixtures, it is possible to attach the lighting fixtures to them using magnets, whereby the magnets simultaneously create the electrical contact between the lighting fixture and the conductor element. The different potential of two adjacent conductor elements, each of which has a light contact on its surface, creates a closed circuit, the power supply of which is easily provided, for example, using magnetic contacts of the power supply lines that adhere to the conductor elements. The lights can be moved quickly and easily by moving the magnetic lighting fixture contacts.

&Ggr;.another advantage of the conductor elements made of magnetic material is that they can be fixed to the ceiling or wall to be covered by means of magnets attached there. It is thus possible to arrange the conductor elements on

\ easy way to vary.

&bull; If the conductor elements are rails, several

They can be arranged parallel to one another, at an acute angle or at right angles to one another, with adjacent conductor elements always having a potential difference. In this way, it is possible to move the lighting fixtures on the available surface spanned by the conductor elements in such a way that a different lighting structure is always created. The magnetic contacts of the power supply ensure further variation! If further elements are added to the existing conductor elements, they can be wired by simply moving the magnetic contacts and adding further connecting cables equipped with magnetic contacts between the individual conductor elements, which cannot be done without considerable effort with the previously known, permanently installed power rails integrated into the ceiling or wall structure with their fixed wiring.

The plates are connected to the power source connections via magnetic contacts. Conductor sections, also equipped with magnetic contacts, run from these plates to neighboring plates. The individual plates are connected in such a way that, with plates arranged in an equatorial manner, two horizontally or vertically neighboring plates are at different electrical potentials. The lighting fixtures can thus be arranged practically at any point on the covered surface or in any constellation relative to one another using their magnetic contacts.

The arrangement of the panels can also be varied using the magnetic fastening on the wall or ceiling. When planning the room lighting, for example, a fastening point grid can be defined. The panels can then be arranged in any position on this grid, e.g. in a checkerboard pattern or offset from one another, with the side

edges of the plates can either be parallel to each other or at an angle to each other.

-Another advantage of the panels is that insulation material can be placed between them and the ceiling/wall, which has a sound and/or heat insulating effect.

Furthermore, the surfaces of the panels serve as reflectors, which, due to their respective arrangement, produce a wide variety of optical effects.

The reflector effect of the plates can be increased or reduced if the plates are provided with a wide variety of conductive surfaces according to claims 6 to 8. The plates can be chrome-plated, anodized or provided with an electrically conductive paint. In conjunction with the magnetic fastening of the plates, this also makes it possible to arrange plates with different surfaces next to one another without requiring major structural modifications.

The lighting fixtures according to the invention can be mounted on brackets or on strips that can be pivoted at the ends of which the magnetic contacts are arranged. If brackets are used, the

Possibility of directing the lights towards the line elements, for example. This creates an indirect type of lighting, whereby the reflector effect of the elements can be cleverly exploited.

In the following, the invention is illustrated and explained in more detail using drawings.

-Fig. 1 shows a lighting system in which rails (1, 2) arranged parallel to one another are used as conductor elements. These rails (1, 2) are held in position by means of magnets attached to the base (3). As can be seen from Fig. 1a, the rails (1, 2) can have a U-shaped profile in cross section, but they can also be rectangular bars in cross section. The rails are made of a magnetic material, such as magnetized stainless steel. A pair of rails (1, 2) (the left pair of rails in Fig. 1) is connected to the poles of a voltage source, e.g. the secondary winding of a transformer. The lines (5, 6) leading from the transformer to the rails (1, 2) end at magnets (7, 8) that adhere to the inside (1, 2) and establish the electrical contact between the lines (5, 6) and the rails (1, 2). The rails (1, 2) are therefore each at a different electrical potential. The rails (1) are each connected to one another via lines (9), while the rails (2) are connected to one another via lines (10). The electrical contact between the lines (9, 10) and the rails (1, 2) is also established via magnets (11). Between each rail (1) and each rail (2) there are

Lighting fixtures (12) are arranged. The lighting fixtures (12) are supplied with power using magnets (13) attached to the front of the rails (1, 2) to _which cables (14) leading to the lamp holder of the lighting fixture (12) are connected. Low-voltage halogen lamps are used for the lighting fixtures (12). The lighting fixtures (12) can now be easily moved on the rails (l _f 2), both in a direction along the rails and in a direction across them.

Fig. 2 shows a further embodiment of the invention. Here, the conductor elements are square plates made of magnetic material. The plates are provided with the reference numerals (20 and 21). The plates (20, 21) adhere to magnets (23) attached to the base (22) _{, as} shown in the example of the upper right plate in Fig. 2. As can also be seen from Fig. 2, the two adjacent lower plates (20, 21) are each connected to the conductor (24, 25) of an indicated voltage source. The contact between conductors (24, 25) and the plate surface facing the base is made by magnets (26, 27). Plates (20, 21) placed diagonally to one another are connected to one another by means of electrical lines (28, 29). The contact between the conductors (28, 29) and the corresponding

As can be seen from Fig. 3, the magnets (32) are located on the ends of a bracket (33) to which the lighting element (31), a low-voltage halogen lamp, is attached, e.g. pivotably.

In Fig. 4, two diagonally opposite plates (21) are shown in section, which are electrically connected to one another by a line (29), whereby the electrical contact between the plates (21) and the line (29) is established by two magnets (30).

The plates (20, 21) can be made of magnetized stainless steel. However, they can also be made of any other magnetic material, for example, the surfaces of the plates being coated with a conductive galvanic coating.
