Description

The invention relates to a lamp for a modular lighting system. The invention also relates to a modular lighting system with at least two such lights and a connecting piece for a lighting system.

Luminaires are widely known from the prior art. Such lights are used, for example, to illuminate rooms, for example offices. To illuminate large areas such as multi-storey car parks or underground garages, the lights are typically strung together. Often several additional components as well as a lot of cabling and wiring are necessary to assemble the lights.

From the DE 10 2012 005 982 A1 , DE 10 2009 016 629 A1 , DE 10 2008 016 697 A1 , US 2014/0071668 A1 , US 2012/0049739 A1 , US 2010/0277098 A1 , US 2010/0271804 A1 , US 2010/0214779 A1 , US 2002/0114155 A1 , EP 1 980 785 A1 , US 2012/0092875 A1 , US 8313212 B1 and WO 2015/041530 A1 lights and lighting systems are known.

One object on which the invention is based is to provide a lighting concept which contributes to particularly simple assembly.

A lamp for a modular lighting system is disclosed which has a lamp housing designed as a tube with a first end and a second end opposite the first end, the lamp housing having an outer shape which is adapted to a predetermined retaining clip. The lamp has a plurality of lighting means which are arranged within the lamp housing. The first end has an electrical first plug connection. The second end has an electrical second plug connection. The first plug connection is electrically coupled to the plurality of illuminants for their power supply and to the second plug connection. The lamp can be coupled to the further lamp directly and / or by means of a connecting piece by means of one of the two plug connections via a first or second plug connection of a further lamp. The first plug connection and / or the second plug connection are designed such that the lamp is coupled to a further lamp in a direction essentially perpendicular to a longitudinal axis of one of the lamps. Part of the lamp housing is made of a metal material and the part is designed as a protective conductor.

The lamp described can optionally be coupled directly or indirectly to the further lamp. The lamp can preferably be plugged together directly or indirectly with the further lamp. For example, the lamp is plugged together directly with another lamp. As a result, both lights are mechanically fixed to one another and electrically connected. For example, the lamp is plugged directly into a first plug connection of the further lamp via the second plug connection. Conversely, it is possible that the light can be plugged into a second plug connection of the further light by means of the first plug connection. In other words, it is possible to plug together one end of the lamp and one end of the further lamp.

Alternatively, the two lights can be plugged together using a connector. For example, one end of two lights is plugged directly onto the connector in a similar manner. By coupling the two lights, both lights are electrically connected. In this way, a power supply for the further lamp is achieved via the first lamp. In other words, the two lights are electrically connected in series.

In this context, a direct connection or direct plugging of the two lights is understood, for example, to mean that the first or second plug connection of one light is plugged directly into the corresponding plug connection of the other light without a cable.

The lamp described contributes to a modular lighting system that can be installed quickly and easily. In particular, a simple, modular plug-in system for lamps is made possible. For example, several of the luminaires described are plugged together directly, so that a rapid, modular stringing together of luminaires can be implemented as required. Optionally, two lights can be lined up next to one another or spaced apart from one another via the connecting piece. Furthermore, lighting systems of any configuration are possible depending on the design of the connecting piece. For example, star-shaped, cross-shaped, angled and / or straight arrangements of coupled lights are conceivable. In this way, the illumination of an area or room can be varied and adjusted in a targeted manner. The luminaires are plugged together with one another or with the connecting piece, for example, in a non-positive and / or positive manner, so that a plug connection is achieved. This plug connection can be released again without being destroyed.

Only a few steps are necessary to couple two lights. Furthermore, the assembly can also be carried out by a layperson, since it is not necessary, for example, to carry out wiring or the like yourself. Furthermore, it contributes to a low cabling effort. For example, it is only necessary to connect a first lamp of a lighting system to a power supply. For example, only one connection cable from a socket to the first lamp is necessary for this. Further cabling is not absolutely necessary to connect the lights. Furthermore, the luminaire has proven to be advantageous for illuminating large areas or rooms such as underground garages, since a large number of luminaires typically required can be installed quickly and with comparatively little effort.

The two plug connections are plug connectors. The first plug connection is, for example, a plug. The second electrical plug connection is, for example, a socket or coupling. The first plug connection and the second plug connection are, for example, an integral part of the lamp. In other words, the two plug connections are integrated into the luminaire housing or part of the luminaire housing. The lamp housing is essentially rigid.

The lamp, in particular the first plug connection and / or the second plug connection, is for example for a low-voltage network, for example with a mains voltage of 220 volts, 230 V to 400 V in Europe (depending on whether single-phase or three-phase) or 110 volts in the USA, designed. For example, the first plug connection and the second plug connection are designed so that they can carry the entire current of a standard automatic circuit breaker. In other words, several lights can be electrically coupled up to a current load limit of the circuit breaker. This makes it possible to string any number of lights up to a load limit of the corresponding power grid.

The luminaire housing is designed as a tube. For example, the lamp housing has a constant cross-sectional profile. For example, the lamp housing is cylindrical. This helps to put several lights together in a straightforward way in a simple way. This contributes to the illumination in lanes or strings, as is typically used in parking garages or the like. The two plug connections are part of the tube and are arranged parallel to a central longitudinal axis of the tube. In particular, the two plug connections cannot be tilted or bent with respect to the central longitudinal axis in normal operation.

The lamp housing has an external shape that is adapted to a predetermined retaining clip. The predetermined retaining clip is, for example, a standardized retaining clip or a standardized retaining clip. In other words, the lamp housing has predetermined dimensions with respect to an outer circumference. For example, it is a holding clip of the DN25, DN30 or the like. As a result, the luminaire can simply be snapped or clipped into commercially available retaining clips or retaining clips and it is not absolutely necessary to keep other special components available for assembly. It also helps to ensure that no heavy or bulky parts have to be held up and mounted overhead when installing the lights. Only the lights have to be clipped or plugged into the retaining clips.

A part of the lamp housing is made of a metal material, in particular aluminum. The part of the light housing is, for example, a lower part or an upper part of the light housing. For example, the part of the lamp housing is designed as an extruded aluminum profile. The metal material contributes to an improved heat transfer, in particular an efficient cooling of the lamp. For example, the waste heat generated by the lighting means can be better dissipated from the luminaire housing into the environment. For example, the luminaire housing is designed in two parts, the top being made of a transparent material, for example glass or a transparent plastic. For example, the transparent upper part has a prismatic design. This helps to optimize the light distribution. Alternatively, the luminaire housing is made entirely from a plastic or glass material, at least the upper part being transparent. In a further alternative, the lamp housing is made in one piece.

The part of the lamp housing that is made from a metal material is designed as a protective conductor. This contributes to the fact that no further, separate electrical line has to be provided from the first plug connection to the second plug connection. The part of the lamp housing thus fulfills several functions at the same time, namely as a protective conductor, cooler and contact protection.

The first plug connection and / or the second plug connection are designed such that the Light with a further light in a direction essentially perpendicular to a longitudinal axis of one of the lights, for example directly, can be coupled, for example plugged together. In other words, the lights can be brought together in this direction. This has the advantage, for example, that when a number of luminaires are lined up, for example plugged together, a single luminaire that is arranged in the string can be easily replaced without a large number of other luminaires having to be dismantled. The corresponding lamp can thus easily be pegged or dismantled perpendicular to the longitudinal axis.

In one embodiment, the first plug connection has blade contacts that can be inserted laterally into the second plug connection of a further lamp. Subsequently, by means of a rotatable ring which is provided on the first plug connection or the second plug connection, a fuse can optionally be brought about, which prevents the blade contacts from being unplugged.

In a further embodiment, the plug-in connections are designed in such a way that the contact is made when plugging together via lateral contacts or via a central bore, the contact being made by plugging together in a direction perpendicular to the longitudinal axis.

According to a further embodiment, the lamp has suspension means for hanging the lamp on a wall, in particular a ceiling. For example, it is a predetermined retaining clip as explained above, which has an eyelet or a hook for hanging. This has the advantage that tensions are avoided or reduced, which can occur with uneven walls as a result of the suspension of several lights that are directly plugged together. The direct plugging together of the lights results in a stiff construction, which can lead to mechanical stresses. Such tensions can also or alternatively arise due to thermal expansion of the luminaire during operation. In other words, it is a question of flexible suspension means that help to equalize tension by allowing the lights to move when they are suspended.

According to a further embodiment, the lamp housing is designed to be rotatable with respect to the first plug connection and / or the second plug connection. This makes it possible to rotate the luminaire housing into a desired orientation after assembly. This allows the direction of the light generated by the lighting means to be varied and / or adjusted. In other words, a beam angle of the lamp can be adjusted.

According to a further embodiment, the first plug connection and the second plug connection are electrically connected directly in an interior of the luminaire housing. In other words, no electronic components such as capacitors or other loads are interposed or arranged in the direct connection. For example, at least the current-carrying conductors such as the phase conductor and the neutral conductor of the first plug connection and the second plug connection are directly electrically connected. As a result, the power supply is looped through from the first plug connection to the second plug connection.

According to a further embodiment, the first plug connection has a movable element which has plug contacts and can be moved relative to a longitudinal axis of the lamp. The plug contacts are, for example, rigidly connected to the movable element and can thus be displaced. The movable element can be moved, in particular pulled, relative to the lamp housing towards the center of the lamp. This movable element can optionally have one or more latching elements and / or a spring element, for example be spring-loaded. The latching or the spring element are designed to hold the plug connection or the movable element in the “plug-in position” so that the lights cannot be easily removed when they are plugged together. In other words, the movable member is prevented from being shifted toward the center. This alternative offers the advantage, for example, that simple sealing with O-rings is possible. According to a further embodiment, a cable duct is formed in the lamp housing. For example, the cable duct can be accessed separately. For example, the cable duct is provided with a detachable cover that is part of the lamp housing. For example, the cable duct is formed separately in the lamp housing. This makes it possible to route or forward additional lines or cables via the cable duct. For example, data cables can be passed on like a LAN cable (abbreviation for Local Area Network).

According to a further embodiment, the lamp has a power supply unit which is arranged within the lamp housing. The power supply unit is provided, for example, to convert the voltage applied to the first plug connection to a low voltage for the lighting means. This contributes to the fact that the power pack does not have to be kept outside the lights, for example in the form of a separate power pack. Rather, the power pack is integrated into the light.

According to a further embodiment, the first end or the second end of the lamp housing has a latching means. For example, has the first or second plug connection on the latching means. This makes it possible to lock the lamp when plugging together with another lamp or when plugging together with a connector. This contributes to a secure attachment of the light to another light or the connector.

According to a further embodiment, the light means are LEDs or OLEDs. This contributes to the low power consumption of the luminaire.

According to a further embodiment, the first plug connection and / or the second plug connection has more than two poles. For example, the first plug connection and the second plug connection are designed with three poles, one pole serving as a protective conductor. For example, in addition to current-carrying poles such as phase and neutral conductors, one or more further poles can be provided which are used for further looping through of power supplies or for conducting data signals.

According to a further embodiment, an end cap is pushed onto the first plug connection or the second plug connection. For example, a lamp located at the end of a plug-in system can be closed with the end cap. For example, the end cap is designed so that water and / or dust tightness is achieved at the corresponding end of the lamp. For example, the end cap has a sealing element such as an O-ring.

Furthermore, a modular lighting system is described which has two lights according to the above-described configurations, the two lights being plugged together directly.

Furthermore, a modular lighting system is described which has at least two lights according to one of the configurations described above. Furthermore, the lighting system has a connecting piece, the connecting piece having an electrical first connection terminal which is designed in accordance with a first plug connection of a lamp and a second electrical connection terminal which is designed in accordance with a second plug connection of a lamp. The connecting piece is plugged together via the first connection connection with the second plug connection of one lamp and via the second connection connection with the first plug connection of the other lamp. This means that both lights are electrically coupled to one another.

The lighting systems essentially enable the aforementioned functions and advantages. The lighting systems described contribute to a modular structure. In particular, as described at the beginning, this contributes to simple and quick assembly. It should be pointed out at this point that a combination of the two lighting systems as described above is possible. For example, several lights are provided, some of which are plugged together directly and some of which are electrically coupled to one another via a connector.

The connecting piece can for example be provided preassembled in different lengths. Depending on requirements, a distance between two lights attached to it is determined by means of the connecting piece. For example, the distance is ensured particularly easily and reliably if the connecting piece is made essentially rigid. For example, the connection piece has a substantially rigid or slightly elastic housing which has the first and the second connection connection at opposite ends.

According to one embodiment, a housing of the connecting piece is at least partially adapted to the light housing of a light in its external dimensions. This makes it possible, for example, that not only the lights but also the connecting piece can be clipped into predetermined retaining clips, as described above. This contributes to simple and inexpensive assembly.

In one embodiment, the connection terminals of the connector are connected by means of a cable connection. This contributes to an inexpensive implementation. For example, the connecting piece has a plug and a coupling or socket, which are connected via a cable connection.

According to one embodiment, the connection piece has a plurality of first connection connections and / or second connection connections. In other words, the connector is a distributor. For example, the connection piece is star-shaped, cross-shaped or Y-shaped so that one or more lights can be plugged in in different directions.

According to one embodiment, a connection terminal for a power supply is provided on the connecting piece. The further second connection terminal is designed, for example, as a coupling or socket to which a lamp can be plugged. This provides the power supply for one or more lights via the connector. In other words, for example, they all become direct or indirect lights connected to the connector are supplied with power.

According to one embodiment, the power supply unit is provided in the connecting piece. This means that power supply units do not necessarily have to be present in the luminaires themselves.

According to a further embodiment, the connecting piece has a flexible housing. In this way, for example, tolerances in the assembly of the lights are compensated for.

Furthermore, a connection piece for a lighting system according to the embodiments described above is described. The connecting piece has at least one electrical first connection terminal, which is designed according to a first plug connection of a lamp described above, and a second electrical connection terminal, which is designed according to a second plug connection of a lamp described above.

The connecting piece essentially enables the aforementioned advantages and functions.

Further advantages and functions are specified in the following detailed description of exemplary embodiments.

1 shows a modular lighting system in a schematic, perspective view 1 with at least two lights 2 . The two lights 2 are designed identically. The following should be characteristics of a lamp 2 are described, this also applies to each additional lamp 2 .

Every lamp 2 has a luminaire housing 3 , which is made in two parts and an upper part 4th as well as a lower part 5 Has. The top 4th and the lower part 5 are to the housing 3 composed. The luminaire housing 3 is formed as an elongated tube or tube and cylindrical. The top 4th is transparent and is made of a transparent plastic. The lower part 5 is made of an aluminum material. The lower part 5 is an aluminum extrusion profile. The luminaire housing 3 is optionally waterproof and dustproof.

The luminaire housing 3 a lamp 2 has two opposite ends 6th and 7th . At the first end 6th is a first plug connection 8th and at the second end 7th is a second plug connection 9 educated. With the first plug connection 8th it is a plug with two plug contacts 10 . With the second plug connection 9 it is a socket with two corresponding socket contacts. The two plug contacts 10 are designed as neutral and phase conductors. The same applies to the socket contacts. The first plug connection 8th serves as the power supply input and the second plug connection 9 as a power supply output. The two plug connections 8th and 9 are designed for power supply with a mains voltage, for example 230 V, and can carry the entire current of a standard circuit breaker. The two plug connections 8th , 9 are rigidly connected to the luminaire housing.

In 3 is a schematic, partially broken view of a lamp 2 shown in more detail. It can be seen that the lamp 2 a variety of light sources inside 11 Has. The bulbs 11 are LEDs in the exemplary embodiment. The LEDs are on a circuit board 12th or board arranged. The circuit board 12th is inside the luminaire housing 3 fixed and arranged. For example, the circuit board is 12th on the lower part 5 or the top 4th set. Alternatively or additionally, the circuit board is locked 12th in the luminaire housing 3 . The two plug contacts 10 are via connecting cables 13 with a power supply 14th electrically connected. The power supply 14th converts the to the plug contacts 10 applied voltage accordingly for the supply of the lamps 11 on an operating voltage for the lamps 11 , for example 2 to 3 volts. The power supply 14th is designed for converting the voltage of a low-voltage network up to 230 volts (single-phase system). Furthermore, the plug contacts 10 directly with further connection lines 15th connected directly to the corresponding contacts of the second plug connection without the interposition of further components 9 are connected. There is thus a power supply from the first connector 8th to the second plug connection 9 looped through.

The two plug connections 8th and 9 a lamp 2 are designed in such a way that they are fitted with corresponding plug-in connections 8th , 9 another lamp 2 can be plugged together directly. This creates a plug connection. This is for example in 2 indicated. In particular, the one lamp 2 by means of the first plug connection 8th (Plug) directly into the second plug connection 9 (Socket) of the other lamp 2 be plugged. Thus the two lights can 2 be plugged together electrically in series in a simple manner. In other words it becomes a lamp 2 a further luminaire arranged directly next to one another 2 extended. The joining of two lights 2 takes place positively and positively. This makes the two lights 2 fixed directly to each other. The two plug connections 8th , 9 are, for example, convex, while the plug contacts 10 or the socket contacts are designed to be floating. This allows tolerances, for example those caused by manufacturing technology, to be compensated.

To power the two lights 2 becomes a lamp 2 to an existing power grid via the first plug connection 8th connected and supplied with mains voltage. 4th Figure 12 shows an exemplary embodiment in which a junction box 15th is provided via a connection cable 16 with a cable coupling 17th connected is. The cable coupling 17th is connected directly to a first plug contact 9 a lamp 2 plugged.

For the lighting system 1 a connection to a power grid is therefore only necessary at one point. The power supply of a lamp 2 becomes the second plug connection 9 the lamp 2 durgeschried and supplies the next one, on the lamp 2 attached light 2 with electricity. Alternatively, a socket is provided, for example on a ceiling or wall. All that needs to be done is a connection cable for connection to a first lamp 2 to be installed.

As in 1 shown schematically, the lighting system 1 Retaining clips 21st on. The lamp housing 3 of lights 2 are in their outer shape, so in particular their outer dimensions, on the retaining clips 21st customized. With the retaining clips 8th it is, for example, standardized retaining clips according to the DN25 standard. These are usually mounted on a ceiling or wall, for example in an underground car park. Then the lights must 2 simply clicked, snapped or clipped into the retaining clips. No tools or fasteners are required for this.

The two plug connections are as described 8th and 9 designed for a power supply with 220 V and can carry the entire current of a standard circuit breaker. This allows the lighting system described 1 any number of lights 2 can be expanded to the load limit of the power grid, which are connected in series.

The lamp described 2 enables quick and easy assembly of a modular lighting system 1 . Depending on your needs, there will be a plurality of lights 2 in retaining clips 21st clipped in and plugged together directly. It should be mentioned here that more than that in 1 and 2 shown lights 2 can be plugged together. There just needs to be a light in one place 2 be connected to a power supply such as a low voltage network. Furthermore, the lights allow 2 an integration of these in existing cable installations or cabling with the predetermined retaining clips 21st .

Optional is as in 2 shown on the second connector 9 a sealing element 22nd provided as an O-ring. This is between two connected lights 2 Achieved water and dust tightness. Alternatively or additionally it is on the first plug connection 8th another sealing element is provided.

In the exemplary embodiment, the two plug contacts 10 or corresponding sockets designed with protective insulation. Alternatively, the first plug connection 8th and the second plug connector 9 designed with multiple poles.

For example, in addition to the phase and neutral conductors, a third pole is provided as a protective conductor.

In an embodiment not shown, the lower part is used 5 , which is made of aluminum, as a protective conductor. It is therefore only necessary to provide a third pole, the one on the first plug connection 8th with the lower part 5 is electrically connected. The third pole of the second plug contact 9 is in the area of the second end 7th with the lower part 5 electrically coupled. This means that it is not necessary to connect the third pole to another wire line in the lamp housing 3 from the first end 6th until the second end 7th respectively.

In further exemplary embodiments, not shown, one or more additional poles in addition to the neutral conductors and phase conductors can be connected to the first plug connection 8th or the second plug connection 9 be provided. For example, further power supplies or data signals can be passed on or looped through via the other poles.

In the exemplary embodiment, as described, the power pack is part of a lamp 2 itself. In alternative configurations, the power pack can also be part of the connection coupling 17th be.

In alternative, not shown exemplary embodiments, the lamp housing 3 made entirely of a transparent plastic or glass. In further alternative exemplary embodiments, not shown, at least the upper part 4th made of a transparent material such as plastic or glass. In further exemplary embodiments not shown, the lamp housing is 3 designed in one piece and made of a transparent plastic or glass. In further exemplary embodiments, not shown, the lamp housing is in two or more parts and is made from one or more plastic materials. In further exemplary embodiments not shown, the lower part is 5 made of a different metal material that ensures good heat transport.

In the exemplary embodiments not shown, the lamp housing is 3 rotatable with respect to one or both plug connections 8th and 9 educated. This can change the beam angle of the lamp 2 can be set. This is advantageous, for example, when the lamp 2 is already mounted on a ceiling and the direction of the light can easily be varied.

The 5 to 7th show further exemplary embodiments of lighting systems 1 . In each of the other lighting systems 1 several of the already based on 1 to 3 described lamp 2 used.

In each of the other lighting systems 1 is at least one connector 18th shown. By means of the connectors 18th can have two or more lights 2 are put together indirectly. The connectors 18th are basically designed to provide a power supply from one or more connected lights 2 to other connected lights 2 loop through. The connectors 18th can also be referred to as distributors.

In the in 5 The embodiment shown represents the connector 18th represents an extension and has a first connection terminal 19th and a second connection port 20th on. At the first connection port 19th it is a plug that corresponds to a first plug connection 8th a lamp 2 is trained. At the second connection port 20th it is a socket that corresponds to the second plug connection 9 a lamp 2 is trained. This allows the lights 2 directly to the connector 18th plugged in and thus electrically coupled.

The connector 18th has a housing 23 on and is in its external shape the lights 2 customized. In other words is the diameter of the case 23 the diameter of the lights 2 customized. Thus, the connector 18th also in the predetermined retaining clips 21st be clipped in. This makes assembly of the lighting system particularly easy 1 contributed.

The case 23 of the connector 18th is designed as a corrugated pipe. In addition to basic rigidity, there is therefore a slight elasticity. In this way, for example, tolerances during assembly can be compensated and a path of luminaires lined up 2 to be influenced. However, this is not absolutely necessary.

By a predetermined length of the connector 18th can be a distance between two lights 2 To be defined. This enables the illumination of a room or area to be influenced in a targeted manner.

In 6th is another lighting system 1 with three lights as described above 2 and another connector 18th shown schematically. The connector 18th is designed as a T- or Y-piece and has a first connection connection 19th two second connection ports 20th . The two second connection ports 20th are on two Y-sections 24 of the connector 18th arranged. The connections 19th and 20th correspond to those described above. The three lights are analogous to the above 2 to the connector 18th plugged directly. By means of the connector shown 18th becomes a power supply from a lamp 2 (in 6th the left lamp 2 ) to two other lights 2 passed on. This is another way of configuring a lighting system 1 shown.

The connector is the same as above 18th optionally at least partially designed as a corrugated pipe and slightly elastic.

7th shows schematically another lighting system 1 with four lights as described above 2 and another connector 18th schematic. With this connector 18th it is a distribution block with two first connection ports 19th and two second connection terminals 20th . So there are four lights 2 attachable from four sides. The power supply is provided by a lamp 2 on the others on the connector 18th connected lights 2 sanded.

It should be noted at this point that the connecting pieces described are only to be understood as examples and further designs are conceivable without deviating from the idea of the present application.

For example, it is conceivable that the connecting pieces 18th have a power input connector. The power input connection is, for example, according to the first plug connection of a lamp 2 trained and connected to a power grid. Such a connecting piece only has further second connecting connections 20th on, which are designed as a socket. Lights are attached to these sockets 2 connected as described above. So there is no need for a lamp 2 can be connected directly to the mains, but the lights 2 are via the connector 2 powered.

In further, not shown exemplary embodiments, the connecting pieces 18th a power output connection through which power can be decoupled for additional consumers or other lights.

It is also conceivable that the power supply unit described above is not part of the lights 2 is, but in the connectors 18th is integrated.

8th shows a lamp 2 , at the end of it 7th no further light or connector 18th connected. For example, it is a terminal lamp 2 of a lighting system 1 . On the end is an end cap 25th pinned that the end 7th or the second plug connection 9 closes water and dust tight. The end cap 25th has two plug contacts for insertion into the corresponding socket contacts of the lamp 2 on.

9 shows a further embodiment of a lamp 2 . In addition to the features already described, the lamp 2 a cable duct 26th in the luminaire housing 3 educated.

11 to 13 show further exemplary embodiments of lighting systems 1 with at least two lights 2 in schematic, perspective partial views. The lights 2 are designed in accordance with the exemplary embodiments described above and differ in the plug connections 8th , 9 , as described below. The other exemplary embodiments contribute to a simple (dis) assembly of a single light 2 when, for example, in a chain of several lights connected together 2 needs to be replaced.

11A and 11B show an embodiment in a disconnected and assembled state of two lights 2 .

The first plug connection 8th has a moving element 31 , on which rigid plug contacts 10 are arranged. The moving element 31 can be moved with respect to the luminaire housing 3 arranged. There is a guide for the movable element 31 intended. In the exemplary embodiment, the movable element is 31 tubular and surrounds the luminaire housing 3 form-fitting, which serves as a guide. Other arrangements are possible. The guide can be designed "over-square" and prevents it from getting stuck when moving.

The moving element 31 can to the center of the lamp 2 towards relative with respect to a central longitudinal axis 32 moved (see double arrow 38 ) so that the plug contacts 10 from the corresponding socket contacts of the second plug connection of the further lamp 2 (left lamp 2 in 11A , 11B) can be drawn. The luminaire housing 3 remains in position. This allows the right lamp 2 from the left lamp 2 can be unplugged without having to connect several luminaires connected together 2 (for example ten such lights 2 to the right of the in 11A , 11B shown lights 2 ) several lights 2 must be dismantled to the corresponding luminaire 2 to mark out. Thus a single luminaire can 2 can easily be dismantled. It just needs the moving element 31 be withdrawn and the lamp then in a direction perpendicular to the central longitudinal axis 32 subtracted from. It should be noted that another lamp 2 to the right of the lamp shown 2 is plugged, also, for example by withdrawing a corresponding movable element, from the lamp to be dismantled 2 must be decoupled.

For plugging together and contacting the plug contacts 10 must be the moving element 31 just like in 11B can be moved to the left into the "plug-in position".

The moving element 31 can in the plug-in position according to 11B with the other lamp 2 , for example the second plug connection 9 lock into place. Optionally, a lock can be attached to the first connector 8th and / or the second plug connection 9 be provided to secure the position. Optionally, the movable element 31 be spring-loaded so that the movable element 31 is pressed outwards from the center of the lamp due to a spring force. For example, inside the lamp housing 3 a spring element arranged.

Optional has the movable element 31 a partial recess 33 in one of a light exit side of the lamp 2 assigned area. This avoids covering the light source in order to be able to emit more light.

Optionally, the lamp 2 have one or more membranes that ensure pressure equalization when two lights are plugged together. In particular, when the movable element is displaced, pressure can build up inside the lamp, since the interior is typically sealed. This pressure is compensated for by the membrane or membranes. For example, every first plug connection is in the area 8th a membrane inside the lamp 2 installed. This contributes to a simplified plugging process.

12th shows a further embodiment in a perspective, schematic partial view. The first plug connection 8th has two blade contacts 33 on, the laterally in a direction perpendicular to the central longitudinal axis 32 of lights 2 be introduced. The second plug connection 9 has a relation to the lamp housing 3 around the longitudinal axis 32 twistable ring 34 on that one opening 35 which is in a position so that the blade contacts 33 can be inserted. Then the ring 34 twisted so that the blade contacts are led out 33 is prevented. The ring 33 can optionally be provided with knurling for better manageability.

13 shows a further embodiment in a perspective, schematic partial view. The first and second connector 8th , 9 are designed so that they can be plugged in from the side in a direction perpendicular to the longitudinal axis 32 is possible. The second plug connector has a recess for this purpose 36 which is open at least in one direction perpendicular to the longitudinal axis, so that a contact area 37 of the first plug connection 8th can be received in the recess. The contacts 10 be arranged laterally or centrally, for example in a bore 39 be arranged.

The examples described according to 12th and 13 enable insertion perpendicular to the longitudinal axis and thus, as described above, a simple exchange of a lamp 2 in a group of several luminaires plugged together 2 of a lighting system 1 .

The lighting systems described 1 can also be combined and / or expanded as required. Thanks to the lamp described 2 A large number of these can be coupled depending on requirements and application. For example, lighting systems can be generated in which lights 2 partly via connectors 18th and some are directly linked. The lighting systems described 1 are not on the number of lights shown in the figures 2 limited.
