EP2474966B1 - Light with holder unit and disc-shaped light module - Google Patents

Description

The present invention relates to a luminaire according to the preamble of claim 1, which has a directly or indirectly to be fixed to a wall or ceiling support unit and a disc-like light module, via which a surface light emission takes place. In particular, the present invention relates to a luminaire which can be used as a so-called escape sign luminaire.

Escape sign lights serve to display information regarding an escape route. In larger building complexes such lights are located at important positions and show even in case of failure of the general power supply and / or other emergencies, the shortest or safest way out of the building.

The classic representation of a rescue route is carried out in that on a transparent surface in the form of a pictogram, a running person is shown, next to an arrow signals the direction of the rescue route. This disc is backlit by appropriate means, so that even in the dark, the appearance of the rescue route is clearly visible.

Since, of course, the direction of the rescue route is dependent on the current conditions, differently designed emergency exit displays must be available in order to be able to indicate the direction of the route in each case. The choice of the appropriate pictogram depends not only on the environment, but also on whether the lamp is mounted on a wall or ceiling.

The document US 3931689A is considered to be the closest prior art.

Since the above-described requirement to provide differently designed icons is associated with a certain amount of effort, the present invention is based on the object of providing novel luminaires in which, for example, the representation of the rescue route can be flexibly adapted to the respective site of use Way of mounting the lamp to a wall or ceiling can be adjusted.

The object is achieved by a luminaire having the features of claim 1. Advantageous developments are the subject of the dependent claims.

The solution according to the invention is based on the idea of using lighting modules which are designed such that they can be arranged on a carrier unit in different positions and / or orientations. It can be provided in particular in the case of a rescue sign light, that the entire icon is divided into individual disc-like lighting modules whose orientation can be set independently. This makes it easy to adapt the direction indicator for the rescue route to the respective site.

Accordingly, the invention proposes a lamp with a directly or indirectly to be fixed to a wall or ceiling support unit, which has means for power supply and corresponding connections. Furthermore, the luminaire has at least one disc-like light-emitting module with one or more light sources and a broad-side light-emitting surface for emitting the light emitted by the light source (s), wherein the light-emitting module is designed to connect the connections for the power supply in a state arranged on the carrier unit to contact. According to the invention, the terminals of the carrier unit as well as terminal areas located on the light module for contacting the terminals are designed such that the light module can be arranged in different positions and / or orientations on the carrier unit, wherein the terminal areas of the light module are formed by contacting tracks, which on the narrow side Peripheral region of the light module are arranged. In this case, these contacting tracks may preferably extend over the entire outer circumference of the lighting module, so that its orientation is essentially freely selectable.

The contacting tracks are, for example, recessed, the terminals of the carrier unit having contact pins which engage in the depressions located on the outer circumference of the lighting module in order to contact the contacting tracks. This solution makes it possible for two lighting modules to be arranged directly adjacent to one another and, despite all this, there is no risk that the contacting tracks will come into contact with one another and, accordingly, a short circuit may occur. Alternatively, however, it may also be desired to touch the contacting tracks directly in order to ensure the power supply via the lighting modules themselves. In this case it can be provided that the contacting tracks are arranged directly on the upper side of the peripheral region.

A single light module itself preferably has a rectangular shape, in particular a square shape. As already mentioned, a plurality of lighting modules can also be arranged on the luminaire, which are then arranged in such a way that a substantially closed light-emitting surface results. In this case, the lighting modules are then preferably designed such that they each have the same or identical shape.

For arranging the lighting modules on the carrier unit, a holding unit is preferably provided. This can be realized in the form of a frame for receiving the lighting module or modules, which is then attached to the carrier unit. The lighting modules themselves are used in the desired position and orientation in this frame, resulting in a very simple quick installation of the lamp. At the same time, the representation of the escape route can be modified quickly and easily in this way.

As already mentioned, the luminaire according to the invention is preferably a rescue sign luminaire. The concept of the lighting modules, which can be arranged flexibly with respect to their position and / or orientation on a carrier unit, could, however, also be transferred to other luminaires, in particular luminaires with the aid of which information is to be displayed.

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

FIG. 1

an embodiment of an inventively designed escape sign and light

FIGS. 2 and 3

the escape sign lamp according to the invention in the representation of different escape route directions.

In the FIG. 1 1 in an exploded view of the invention consists essentially of three different components: a carrier unit 5, one or more lighting modules 10 and provided for holding the lighting modules 10 holding unit 20th

The support unit 5 is used to hold the lamp 1 and is adapted to be attached directly or indirectly to a wall or ceiling. Conceivable would be an immediate attachment to a wall or ceiling, which, for example by not could be done in more detail screws. A spaced arrangement by means of a pendulum or the like would be conceivable. In addition to the holder of the entire lamp 1, a further object of the carrier unit 5 is also to ensure the power supply of the lighting modules 10. For this purpose, the carrier unit 5 internally not shown power supply means, which are designed for connection to the power supply network or to an emergency power supply. Furthermore, internally accumulators or the like can be arranged, which is at least for a certain period after failure of the general power supply still lighting and representation of the rescue route is ensured. On the underside of the carrier unit 5 contact pins 6 are then arranged, via which a connection to the lighting modules 10 takes place.

The lighting modules 10 themselves have a disk-like design and, at least on a flat side, have a transparent light exit surface, via which the light is emitted. The light exit surface 11 is usually provided with a pictogram, the two in FIG. 1 shown lighting modules 10 have different pictograms. While the lighting module 10a has a pictogram in the form of a running person, the second lighting module 10b has an arrow as a pictogram, over which the direction of the directional path is displayed.

Both lighting modules 10 represent separate units, each having independent light sources. These light sources are each arranged in the interior of the light module 10 and are formed or coupled with corresponding optical means that the most uniform possible light output via the light exit surface 11 is achieved. Such measures are known from the prior art and accordingly should not be explained below. The light output can be done both via only one of the two flat sides 11 as well as on both sides.

For coupling with the contacting pins 6 of the carrier unit 5, the lighting modules 10 each have on the outer circumference arranged contacting tracks 12. These are slightly recessed arranged in circumferential grooves in the illustrated embodiment, so that both modules 10 can be arranged directly adjacent to each other without them with their interconnects 12 are interconnected. On the other hand, the contacting pins 6 on the carrier unit 5 are arranged and configured in such a way that they can engage in these depressions and contact the contacting tracks 12.

A special feature consists in the fact that these contacting tracks 12, as shown, extend over the entire peripheral region of the lighting modules 10. This means that the lighting modules 10 can be arranged in different positions on the carrier unit 5. In particular, this opens up the possibility of orienting the second lighting module 10b with the arrow icon in any desired manner and thus to indicate a respectively desired direction of the escape route. The pictogram of the left lighting module 10a can be oriented in different ways, which brings advantages in terms of flexibility in the arrangement of the lamp on a wall or ceiling.

This particularly flexible arrangement of the modules 10 is achieved, in particular, in that the contacting tracks 12 extend over the entire circumference and furthermore the modules 10 have a square shape. In spite of all, it would also be conceivable that the modules 10 have a rectangular shape and then extend the contacting tracks 12 only on two opposite sides, for example on the top and bottom. Also in this case, a certain flexibility in the arrangement of the lighting modules 10 would be given.

The holder of the lighting modules 10 on the support unit 5 by means of the holding unit 20 which is formed like a frame. In particular, the holding unit 20 forms a C- or U-shaped frame 21, the side legs 22 are provided for attachment to the carrier unit 5. This can be done for example by appropriate locking means. By two oppositely arranged discs 23, a receiving space 24 is provided, in which the lighting modules 10 can be inserted in the desired position and orientation. The height of the light exit disks 23 preferably corresponds to the height of the lighting modules 10.

The equipped with the light modules 10 holding unit 20 is then snapped onto the carrier unit 5, wherein at the same time a contacting of the contacting tracks 12 is ensured by the pins 6. After attachment of the carrier unit 5 to a wall or ceiling, thus the entire lamp 10 can be mounted in a simple and fast manner.

By the possibility of arranging the two lighting modules 10 in the desired manner in the holding unit 20 and accordingly on the carrier unit 5, the representation of the escape route can now be adapted in a simple manner. It is only necessary to change the orientation of the light module with the arrow icon and / or the position of the two light modules 10 to exchange. In a simple way, for example, the two arrangements in the FIGS. 2 and 3 be realized, where FIG. 2 shows an arrangement in which a ceiling mounting of the lamp 1 is provided while while FIG. 2 shows an arrangement in which an assembly of the lamp 1 is provided on the wall. It is obvious that the subdivision of the information to be displayed into individual lighting modules 10 with individual pictograms significantly increases the flexibility in the illustration. Regardless of the way in which the luminaire is mounted, the desired direction of the escape route can be displayed in each case without the need for specially configured pictograms adapted to the respective site of operation.

As already mentioned, the present invention is not limited exclusively to escape sign luminaires, but can always be used when information is to be displayed by means of pictograms, wherein at the same time a flexibility with regard to the orientation and / or arrangement of the pictograms is desired. In this case, a variant in which the contacting paths extend completely over the outer circumference of the lighting modules is particularly advantageous. However, it would also be possible for the webs to extend over only part of the circumference. Furthermore, the inventive concept can also be readily varied with regard to the number of lighting modules. It would be conceivable both the use of a single light module, which should be oriented only in the desired manner, as well as the use of more than two light modules.

Another variation of in FIG. 1 Furthermore, it may also be the case that the contacting paths are deliberately arranged on the upper side of the peripheral region of the lighting modules. In this case, two adjacent modules are connected to each other in this way, so that, if necessary, the number of Kontaktierungsstifte on the carrier unit can also be reduced.
