Abstract

The electrical lighting tube (2) has end contacts that engage contacts (10,15) that project from arms (3,13) on a frame (4). Electrical connections are made to a power supply cable (5) that passes along the carrier.

Description

The invention relates to a mounting device for a lamp with at least one first mounting element for releasable attachment of the lamp to a support and with a contacting a supply line for the electrical supply of the lamp Connecting device.

Such a mounting device is known in practice, in which the at least one Luminaire housing and a luminaire arranged in this luminaire by means of screws, a chain, a ceiling bracket, a wall arm or the like is attached to a carrier. Such a beam can directly cover the ceiling, a steel profile, a mounting channel or the like, on which the lamp by means of Rail mounting, ceiling mounting, wall mounting or mast mounting releasably attached is.

In order to supply the lamp electrically, one is known from practice Mounting device a supply line with a connection device within connected to the lamp housing. There is also a separate connection compartment in the luminaire housing provided with appropriate terminals. Furthermore, in this connection the luminaire housing at least one cable entry and have a line leading through which the electrical connecting line on the one hand into the connection space and on the other hand out of this is. Appropriate seals must be made for these cable entries and exits be provided, especially if the lamp is in an explosion-proof Area to be used.

This means that replacing the entire lamp is very time-consuming and also repairs directly to the lamp are difficult to carry out without disassembly, because such lights are installed at great heights, particularly in industrial plants are.

The present invention is therefore based on the object of a luminaire at the entrance to improve the type mentioned in such a way that it is easy and quick to do so assemble and disassemble and at the same time is structurally simple and inexpensive.

This task is related to the features of the preamble of the claim 1 solved in that the connection device is assigned to the mounting element and for releasable attachment of the lamp between it and the mounting element at least one electrical connector is provided.

According to the invention, the supply line is contacted directly in the assembly element and a separate connection compartment in the luminaire housing with corresponding Feedthroughs for the supply line are no longer necessary. Instead it is done the electrical supply of the lamp via a plug connection between it and the mounting element. Such a plug connection can be produced easily and quickly and, depending on requirements, also trained in the appropriate protection class. When assembling or disassembling, therefore, is a time-consuming loosening of the supply line of the corresponding connection terminals is not necessary. The lamp can be detached directly from the mounting element and to a corresponding point Performing a repair or maintenance. Because the lamp always is handled as a whole during assembly and disassembly, are when changing of the lamp no special safety measures to be observed, because According to the invention, the lamp is first disassembled and the corresponding illuminant is removed is exchanged later.

Furthermore, the luminaire can be made more compact because of a separate connection space is no longer necessary to connect the supply line and also corresponding bushings in the luminaire housing are no longer available.

It is conceivable that the connection device is located locally next to the mounting element and optionally provided separately from this. From the connection device must in this case a corresponding connection to the mounting element and to the connector respectively. However, in order to continue the assembly device according to the invention simplify, the connection device can be integrated in the mounting element.

To simplify the laying of the supply line along the carrier, can the supply line can be passed through the mounting element.

To make the contact between the supply line and the connection device easier to design, the connection device can have an insulation displacement device. This means that the supply line can also be stripped without stripping or isolation Cutting through insulation of the supply line by means of the insulation displacement device be electrically connected to the connection device.

To a plug connection between lamp and mounting element in a simple manner To be able to manufacture, the insulation displacement device with a connector part of the connector on an outside of the mounting element electrically connected his.

In order to be able to position luminaires variably on the carrier, this can be done Mounting element be releasably attached to the carrier.

Different exemplary embodiments are conceivable for such a releasable fastening. For example, the mounting element can be screwed to the carrier. Thereby it is relatively firmly attached to the carrier and also with multiple assembly and disassembly there will be no displacement of the mounting element that leads to misalignment could lead with regard to the lamp.

Further examples of a detachable fastening are latching or hanging the Mounting element. The mounting element can also be moved along the carrier and can be set in a correspondingly selected position.

The connector can be designed in a wide variety of ways. An example of one The connector is a circular connector.

If the luminaire is to be used in a potentially explosive area, the Connector be an explosion-proof connector.

Depending on the space required and the arrangement of the lamp, it can be advantageous if the connector part of the mounting element either arranged laterally in this or is arranged at the lower end facing away from the carrier. With side Arrangement of the connector part is essentially the establishment of the connector by moving the lamp in its longitudinal direction, while at the bottom The connector part arranged at the end of the mounting element essentially the lamp is brought up or pivoted from below to the mounting element.

In connection with the mounting element, it is of course possible that the supply line sealed in and / or out of the mounting element. The Supply line is usually routed along the carrier and can several such assembly elements can be passed.

Depending on the design of the plug connection, it is possible that it can be detached alone Attachment of the lamp serves. For example, the connector can be a threaded ring assigned to be rotatable either on the lamp or on the mounting element is attached. This can be on a corresponding threaded part on the other Element are screwed on when establishing the plug connection. There is also the possibility that in addition to the connector on the same mounting element additional holding device for the lamp is provided.

In the case of larger luminaires in particular, it can be considered advantageous if the first mounting element essentially has a longitudinal end and a second mounting element is essentially assigned to the other longitudinal end of the lamp. Thereby the lamp is detachably attached to the support by two mounting elements. In this Connection should be noted that both the first and second mounting element may have appropriate connection facilities, for example the Connection device of the first mounting element, a first lamp, the connection device the second mounting element supplies a second lamp, etc. there serves the second mounting element for detachable mounting of both the first as well as second lamp etc.

However, it is also possible that the second mounting element only for holding the serves the first lamp and another lamp accordingly by a first and a second mounting element is releasably attached to the carrier.

In order to realize the mounting of the lamp in a simple manner, the second mounting element a receptacle for a connecting part spring-loaded in the direction of the lamp exhibit. This is, for example, in the direction of the second mounting element can be pushed in to the plug connection between the lamp and the first mounting element manufacture. The connecting part pushes the lamp towards the first mounting element for establishing the plug connection and for its subsequent maintenance. The spring loading of the connecting part is chosen so that too after the plug connection has been established, force is still exerted by the connecting part towards the lamp. The lamp can have a corresponding Have receptacle in which the connecting part engages.

An example of such a connecting part is a bearing block.

It is of course also possible for a corresponding spring-loaded connecting part protrudes from the lamp and accordingly the second mounting element a receptacle for the in the direction of this spring-loaded connecting part Luminaire has.

To get a certain freedom of movement when attaching the lamp, you can a connecting part between the lamp and the second mounting element, in particular elastic be deflectable. This is particularly helpful when the luminaire is being manufactured the connector pivoted from below to the first mounting element becomes.

In order not to have to arrange the lamp between the mounting elements, Plug connection part on the first mounting element and connecting part on the second mounting element be arranged on the same sides of the mounting elements. In this In this case, it is possible for the lamp to be arranged below the mounting elements, where appropriate mounts from an upper side of the lamp housing project where the other part of the connector or a receptacle or a connecting part are arranged. The brackets can also be arranged in this way be that they are both arranged between the first and second mounting element are, so that in this case again the connecting part and plug part of the first mounting element arranged on mutually facing sides of the mounting elements could be.

In order to make the assembly elements as compact and small as possible, a such mounting element may be plate-shaped. Inside of the plate is in this In case the connection device is arranged. A corresponding connector part can protrude laterally or at the lower end of the plate.

To prevent the lamp from loosening too easily or accidentally, first and / or second mounting element a locking device for locking the lamp have in contact position. Such a locking device is preferably simply manual detachable so as not to unnecessarily complicate assembly and disassembly.

To ensure both the alignment of the lamp with the mounting element and At the same time, certain security requirements can be met between the first and / or a second mounting element and light provided a coding device his. On the one hand, this ensures that the luminaire is only relative in a certain orientation is mountable to the mounting elements. On the other hand, the coding device Ensure, for example, that only properly closed lights can be installed are.

In the case of a simple exemplary embodiment of such a coding device, it can have a plug-in projection and a complementary plug-in recess. The Plug-in projection can protrude from the first mounting element, for example Plug-in recess can be formed in the lamp housing. The recess can be inaccessible if the lamp housing is not closed properly is. There is also the possibility that the plug projection on the lamp housing is arranged and for example only when the lamp housing is properly closed protrudes and into a corresponding recess on the first or second Mounting element engages.

The mounting device can be used for mounting and electrical supply different Shine be trained. Examples of such luminaires are linear luminaires, which can also be explosion-proof. Corresponding lamps of such Linear luminaires are single-pin or two-pin lamps.

The luminaire must be designed to match the mounting device so that the Plug connection can be made and also a bracket via the second mounting element can be done. Such a lamp is characterized for example from that at least one connector part is arranged on it, which is in the contact position the lamp is engaged with the connector part of the mounting device.

In the following, advantageous exemplary embodiments of the invention are described on the basis of the Drawing attached figures explained in more detail.
