Description

The invention relates to a switch cabinet light with light sources, in particular based on light-emitting diodes, consisting of an elongated light housing with a housing body and a translucent cover as well as electrical connection elements and means for universal attachment provided on the light housing, with electrical switching means and an electrical function being provided on or in the light housing triggering proximity or movement sensor is provided, according to the preamble of claim 1, and an upgrade unit with an electromechanical switching contact mounted on a base according to claim 7.

From the German utility model DE 20 2015 009 318 U1 a switch cabinet light with light sources based on light-emitting diodes is already known.

The control cabinet light consists of an elongated light housing with a housing body and a translucent cover. Furthermore, there are electrical connection elements and means provided on the lamp housing for universal attachment. The basic housing body is designed, for example, like a trough. The cross-section of the switch cabinet light is designed in such a way that the light can be fixed with retaining clips. There is also the option of stringing together several luminaire housings.

For this purpose, electrical connectors are provided on the end faces.

Electrical switching means and/or a motion sensor that triggers electrical functions can be provided on or in the lamp housing.

At least one of the front connectors is designed to directly accommodate an electrical connection cable.

Also known is a switch cabinet light of the type described above DE 20 2019 103 273 U1 , wherein the proximity or movement sensor is connected to at least one switching relay having potential-free contacts or a transistor switch in order to activate or deactivate functions independent of the lamp operation and/or to trigger an optical and/or acoustic alarm.

By means of the switching relay or the transistor switch, access to a control cabinet housing the control cabinet light can be monitored and an alarm can be triggered.

The switching contacts of the switching relay or the transistor switch can lead to an external connection that is attached to or in the light housing and is accessible there.

The assembly, comprising at least one proximity or movement sensor, which is connected to at least one switching relay or a transistor switch, can be designed or provided for retrofitting in order to activate or deactivate functions that are independent of the lamp operation.

The control cabinet lights described above have proven themselves in practical use due to their multiple functions and options.

In many cases, however, it is desirable to also make the function of the switch cabinet light dependent on whether a door or other comparable access to a switch cabinet or similar device has been opened or is open for a shorter or longer period of time.

If you work with a known proximity or motion sensor, the light function can be triggered after opening a control cabinet door, but the light then goes back into the inactive state after a time has elapsed without any movement being detected, i.e. the lamps used are switched off by the Power supply disconnected and extinguished. Especially when, for example, adjustment work or electrical measurements or the like are carried out in such a case and the switch cabinet light goes out, there is a not inconsiderable disadvantage.

From the above, it is therefore the object of the invention to specify a further developed switch cabinet light which makes it possible, in particular also primarily, to be activated or deactivated by a door contact switch.

The object of the invention is achieved with the further developed switch cabinet light according to claim 1 or with an upgrade unit according to claim 8, the subclaims comprising at least expedient configurations and developments.

According to the invention, a switch cabinet light with light sources is assumed. The light sources are, in particular, light-emitting diodes.

The switch cabinet light consists of an elongated light housing, for example a rectangular housing with a housing body and a translucent cover, and the light has electrical connection elements.

Means for universal attachment are provided on the lamp housing. These can be magnetic fasteners, mechanical fasteners in the sense of a form fit, but also non-positive fasteners.

Electrical switching means are present on or in the lamp housing and a proximity or movement sensor that triggers electrical functions is provided.

According to the invention, the lamp housing has at least one, preferably flat, fastening surface for an upgrade unit and a socket for electrically connecting the upgrade unit.

The upgrade unit comprises an electromechanical switching contact which is mounted or can be mounted on a base and has a contact lug, which can be shifted in position with the base relative to the lamp housing.

A wired electrical connection can be produced between the electromechanical switching contact and the socket by means of a plug which is complementary to the socket.

Of course, there is also the possibility here of providing a plug on the lamp housing and realizing the wired electrical connection via a socket that is complementary to the plug.

The aforementioned base and the electromechanical switching contact unit with contact lug can also be made in one piece, that is to say the base can be made in one piece with the switching contact, which is located in a relevant housing or housing.

The base has slot-like recesses for guided position shifting and adjustment of the upgrade unit, with the respective desired position being able to be fixed using a positive or non-positive connection.

To fix the upgrade unit, for example, threaded holes are present on the mounting surface of the lamp housing in order to attach the base and thus the upgrade unit by screwing. Guide cams can also extend from the lamp housing and engage in the slot-shaped recesses or corresponding grooves formed on the base in order to allow the upgrade unit to be fastened in a precise position.

The aim of the possible shift in position is to be able to set the electromechanical switch contact with contact lug so that a switching operation can be triggered when the door is opened or closed, depending on the different embodiments of switch cabinets and switch cabinet doors that are present in this regard.

In this respect, the electromechanical switching contact with a contact lug is designed as a door contact, with a contact being triggered depending on an open or closed position of the respective door.

A connected upgrade unit can be activated by means of the electrical switching contact on or in the light housing. This switching means can be designed as a so-called mode switch, different modes being callable after pressing the switching means, designed as a button. The selected mode, for example "upgrade unit activated", can be confirmed or displayed by a corresponding optical or acoustic signal.

In an embodiment of the invention, when the upgrade unit is connected or activated, the proximity or movement sensor of the switch cabinet light is functionally overlaid by the electromechanical switch contact. Thus, the electromechanical switch contact has priority.

The electromechanical switching contact can be designed as an opener or closer.

According to the invention is also an upgrade unit with an electromechanical switch contact mounted on a base with a contact lug, the base having means for positionally displaceable fastening on a surface, and with a wired electrical plug connection for use as a prioritizing door contact switch, in particular for switch cabinet lights.

The invention will be explained in more detail below using an exemplary embodiment and with the aid of figures.

Here show:

• 1 a perspective view of part of a switch cabinet light with an elongated, rectangular light housing, there existing mode switch and a mounting surface for an upgrade unit;
• 2 a perspective view of the upgrade unit, wherein the upgrade unit has an electromechanical switch contact mounted on a base with a contact lug and the upgrade unit has a cable connection with a connected plug;
• 3 a perspective view of the lamp housing 1 , but with the upgrade unit mounted there so that it can be shifted in position, with the plug of the connecting cable already being inserted into the associated socket on the light housing, here in a bulkhead; and
• 4 a basic representation of the possible displaceable positioning and attachment of the upgrade unit on the mounting surface of the lamp housing, the displacement and adjustment is symbolized by an arrow representation.

The switch cabinet light 1 according to the figures consists of a housing body 2 and a translucent cover 3.

There is also a mode switch 4 and an LED indicator light 5 related to the different modes.

On one end of the housing body 2 is a socket 6 for a door contact upgrade unit (see 2 ) intended.

Furthermore, a fastening surface 7 for the upgrade unit is formed on the lamp housing, with two threaded holes 8 for example being introduced in the region of the fastening surface 7 for the non-positive fixing of the upgrade unit.

Instead of the threaded holes 8, however, a simple hole can also be made in the corresponding housing material, in which case self-tapping screws 9 are preferably used for fastening.

The upgrade unit according to 2 assumes a base 10.

How from the 2 until 4 As can be seen, the base 10 has various elongated holes 11 or corresponding elongated hole-like recesses.

These recesses allow shifting (see 4 ) and thus a change in position or storage of the upgrade unit with regard to the control cabinet light.

The base 10 now carries the actual electromechanical switching contact 12. In this regard, it can be assumed that a classic switching contact is housed in a separate housing and is protected.

The switching contact 12 is actuated via a protruding contact lug 13.

The contact lug 13 is designed in such a way that it can come into contact with a surface or edge, in particular a control cabinet door, in order to trigger the switching contact when the door is opened or closed, so that an electrical circuit can be closed or opened, depending on whether the switching contact was designed as an opener or closer.

There is a cable connection 15 between the switching contact 12 and a plug 14.

The design of the plug 14 corresponds to the design of the socket 6.

After the upgrade unit has been attached to the switch cabinet light 1 and the electrical connection has been made by inserting the plug 14 into the socket 6, the additional door contact switch realized in this way is ready for use.

With the help of the mode switch 4, various functions of the control cabinet light can be selected and preset. In principle, however, it is ensured that a proximity or movement sensor 16 of the switch cabinet light 1 is functionally overlaid by the electromechanical switch contact 12 when the upgrade unit is connected or activated, and the switch contact 12 is therefore prioritized.

Due to the possibility of adjusting the upgrade unit, as in 4 shown, a corresponding adaptation to the respective spatial conditions within a switching sick, in particular in relation to a control cabinet door, can be made.
