Luminaire for a modular luminaire system, modular

Lighting system and connector

The invention relates to a luminaire for a modular

Lighting system. Furthermore, the invention relates to a

modular lighting system with at least two such lights and a connector for a lighting system.

Luminaires are widely known from the prior art. Such lights are used for example for the illumination of rooms, such as offices. To illuminate large areas such as parking garages or underground garages, the lights are typically strung together. Often, the assembly of the lights several additional components and a high cabling or

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

It becomes a luminaire for a modular luminaire system

discloses a light housing having a first end and a second end opposite the first end

having. The lamp also has a plurality of

Bulbs, 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-in connection is with the majority of bulbs for their power supply and with the second plug-in connection electrically coupled. The lamp is by means of one of the two plug connections via a first or second

Plug connection of another lamp directly and / or coupled by means of a connector with the other light.

The lamp described can be coupled either directly or indirectly with the other lamp. Preferably, the lamp is directly or indirectly with the other lamp

plugged together. For example, the lamp is directly plugged together with another lamp. As a result, both lights are mechanically fixed to each other and electrically connected. For example, the luminaire is plugged directly into a first plug connection of the other luminaire via the second plug connection. Conversely, it is possible that the lamp can be plugged by means of the first plug connection in a second plug connection of the other lamp. In other words, it is possible to assemble one end of the luminaire and one end of the other luminaire.

Alternatively, the two lights are on

Connector plugged together. For example, one end of two lights is plugged directly to the connector in a similar manner. By coupling the two lights, both lights are electrically connected. As a result, a power supply of the other lamp is achieved via the first lamp. In other words, the two lights are electrically parallel and physically connected in series.

In this context, a direct connection or a direct mating of the two lights, for example, understood that the first or second

Plug-in connection of a luminaire without cable is plugged directly into the corresponding plug connection of the other luminaire. The lamp described contributes to a quick and easy to assemble, modular lighting system. In particular, a simple, modular plug-in system for luminaires is made possible. For example, several of the lamp described are direct and immediate

put together so that, as needed, a fast, modular stringing together of lights can be realized. Optionally, two lights can be strung together directly or spaced from each other via the connecting piece. Furthermore, lighting systems of any configuration are possible depending on the configuration of the connector.

For example, star-shaped, cross-shaped, angled, circular, circular and / or rectilinear arrangements of coupled lights are conceivable. Thus, the illumination of a region or space can be selectively varied and adjusted. The mating of the lights together

or takes place with the connecting piece

For example, non-positively and / or positively, so that a plug connection is reached. This connector is non-destructive again solvable.

For the coupling of two lights only a few steps are necessary. Furthermore, the assembly can also be performed by a layman, since it is not necessary, for example, to make wiring or the like itself. Of

Another becomes a low cabling effort

contributed. For example, it is only necessary to connect a first light of a lighting system to a power supply. For example, this is only one

Connecting cable from a socket to the first light necessary. Other wiring is not mandatory for mating the lights. Furthermore, proves the Luminaire for the illumination of large areas or spaces such as underground garages as advantageous as a typical

necessary variety of lights quickly and with

comparatively little effort can be installed.

The two plug connections are

Connector. The first plug-in connection is, for example, a plug. The second electrical plug connection is, for example, a socket or coupling. The first plug connection or the second plug connection are, for example, more integral

Part of the lamp. In other words, the two plug-in connections are integrated into the luminaire housing or part of the luminaire housing. The luminaire housing is substantially rigid. Alternatively, the first and the second connector are identical, about both as a socket or both plugs. In other words, the light has two female or male connectors. As a result, the mating with another lamp is independent of an orientation of the lamp and simplifies assembly.

The light, in particular the first plug-in connection and / or the second plug-in connection, is for example 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 US,

designed. For example, the first plug-in connection and the second plug-in connection are designed so that they can carry a whole stream of a standard automatic fuse. In other words, a plurality of lights are electrically coupled as desired up to a current carrying capacity limit of the circuit breaker. This allows as many as you want Luminaires to line up to a load limit of the corresponding power grid.

According to one embodiment, the luminaire housing is designed as a tube. For example, the luminaire housing has a constant cross-sectional profile. For example, the lamp housing is cylindrical. This helps to put together several lights in a simple way to a straight-line course. This contributes to illumination in trains or trains, as is typically used in car parks or the like. The two plug-in connections are part of the tube and arranged parallel to a central longitudinal axis of the tube.

In particular, the two plug connections are in

intended operation not with respect to

Center longitudinal axis tiltable or bendable.

According to a further embodiment, the luminaire housing has an outer shape, which corresponds to a predetermined

Retaining clip is adjusted. At 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 clip of the standard DN25, DN30 or the like. This allows the light in easy

commercially available retaining clips or retaining clips are snapped or clipped and it is not mandatory that further, special components are kept for mounting. Furthermore, it is helped to ensure that no heavy or bulky parts held up and mounted overhead. To have to only the lights and / or the connecting pieces are clipped or plugged into the retaining clips.

According to a further embodiment, the luminaire

Hanging means for hanging the lamp to a wall, in particular ceiling, on. For example, it is a predetermined retaining clip as explained above, which has an eyelet or a hook for hanging. This has the advantage of avoiding or reducing stresses that can occur due to the suspension of several lights that are directly plugged together, on uneven walls. The direct mating of the lights results in a rigid construct, which can lead to the mechanical stresses. Such voltages may additionally or alternatively be due to thermal expansions of the luminaire during operation

arise. In other words, they are flexible hangers that help to balance the tension by allowing movement of the lights while suspended.

According to a further embodiment is a part of

Luminaire housing made of a metal material, in particular aluminum. The part of the luminaire housing is, for example, a lower part or upper part of the luminaire housing. For example, the part of the

Luminaire housing designed as extruded aluminum profile. By means of the metal material is an improved

Heat transport, in particular an efficient cooling of the lamp, contributed. For example, by the

Bulb generated waste heat can be better dissipated from the luminaire housing in the environment. For example, the luminaire housing is designed in two parts, wherein the top of a transparent material, such as glass or a transparent plastic is formed.

For example, the transparent upper part is prismatic. This will lead to an optimization in the

Light distribution contributed. Alternatively, that is

Luminaire housing completely made of a plastic or

Glass material formed, wherein at least the upper part is made transparent. In a further alternative, the luminaire housing is made in one piece. According to a further embodiment, the part of the

Luminaire housing, which is made of a metal material, designed as a protective conductor. This will do so

contributed that no further, separate electrical line must be provided from the first connector to the second connector. The part of the luminaire housing thus fulfills several functions at the same time, namely as protective conductor, cooler and contact protection.

According to a further embodiment, the luminaire housing is rotatable with respect to the first plug connection and / or the second plug connection. This will

allows the luminaire housing to rotate to a desired orientation after installation. This can be done

Vary and / or adjust the direction of the light generated by the bulbs. In other words, one can

Set the beam angle of the luminaire.

According to a further embodiment, the first

Plug and the second connector in an interior of the lamp housing electrically connected directly. In other words, there are no electronic components like

Capacitors or other loads interposed or arranged in the direct connection. For example at least the live conductors such as the phase conductor and the neutral conductor of the first connector and the second connector 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 and / or the second plug connection is designed such that the lamp with a further lamp in a direction substantially perpendicular to a

Longitudinal axis of one of the lights directly coupled, about

is pluggable, is. In other words, the lights can be brought together in this direction. this has

for example, the advantage that when several

strung together, roughly mated, the replacement of a single luminaire, which is in the strand

is arranged, can easily be done without a

Variety of other lights can be dismantled. The corresponding lamp can thus be simply staked or dismounted perpendicular to the longitudinal axis.

Optionally, the first and second ports are like this

designed that a lamp can be connected to the connector by means of vertical plug. The two connections are thus designed so that a

corresponding connector can be coupled analogously to the top perpendicular to the longitudinal axis of the tube. In this case, the connecting piece in each case to the first and second

Plug connection of the lamp corresponding

Connection (plug) connections. The connector has two connection terminals so that two lamps can be connected to each other by means of a vertical connection. It is conceivable that the first and second plug connection of the lamp are formed identically, as described above. A corresponding connector also has similar, corresponding plug connections in this case. In the cases described, the connector as

electrical coupling or coupling adapter are called. The connector can be made in one piece, and very compact. For example, these are

Connector and the plug connections of the lamp designed and matched to one another that the infected connector fits substantially seamlessly into the outer dimensions and contours of the lights. For example, a flush mating is achieved, so that there is a continuous luminaire connection. Optionally, the connector detent means for locking to the two

Luminaires or their plug connections. The connector may also optionally include one or more other features as described later.

In one embodiment, the first plug connection

Knife contacts on the side in the second

Plug connection of another lamp can be introduced. Subsequently, optionally by means of a rotatable ring, on the first plug connection or the second

Plug connection is provided, a fuse can be brought about, which prevents staking the blade contacts.

In a further embodiment, the plug-in connections are designed such that the contacting during

Mating via lateral contacts or via a central bore, wherein the contacting by

Mating takes place in a direction perpendicular to the longitudinal axis. According to a further embodiment, the first plug-in connection to a movable element, which

Having plug contacts and is movable relative to a longitudinal axis of the lamp. The plug contacts are, for example, rigidly connected to the movable element and thus displaceable. The movable element is relative to the

Luminaire housing movable toward the center of the luminaire,

especially drawable. This movable element may optionally have one or more latching elements and / or a spring element, for example spring-loaded. The latching or the spring element are designed to hold the plug-in connection or the movable element in the "plug-in position", so that the luminaires in the mated state can not be easily pulled off, in other words, the movable element is prevented from reaching the center This alternative offers, for example, the advantage that a simple sealing with O-rings is possible.

According to a further embodiment, a cable channel is formed in the lamp housing. For example, the cable channel is accessible separately. For example, the cable duct is provided with a detachable cover, which is part of the

Luminaire housing is. For example, the cable channel is formed separately in the lamp housing. This makes it possible to lead or forward additional cables or cables over the cable channel. For example, you can

Data cables such as a LAN cable (short for English Local Area Network) are passed. According to a further embodiment, the light is on

Power supply, which is located within the luminaire housing. The power supply is provided, for example, the voltage applied to the first plug-in connection to a Low voltage for the bulbs to convert. This helps keep the PSU out of the box

Lights, for example in the form of a separate power supply, must be kept. Rather, the power supply is integrated in the lamp.

According to a further embodiment, the first end and / or the second end of the lamp housing on a locking means. For example, the first or second

Plug connection to the locking means. This makes it possible to lock the lamp when mating with another light or when mating with a connector. This contributes to a secure fixing of the luminaire to another luminaire or the connecting piece.

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

According to a further embodiment, the first

Plug and / or the second connector more than two poles. By way of example, the first plug connection and the second plug connection have three-pole design, 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 can be used for further purposes

Loop through power supplies serve or

Direct data signals.

According to a further embodiment is at the first

Plug connection or second plug connection attached to an end cap. For example, one in a plug-in system terminal lamp are closed with the end cap. For example, the end cap is designed so that a water and / or dust-tightness achieved at the corresponding end of the lamp is achieved. For example, the end cap has a sealing element such as an O-ring.

Furthermore, a modular lighting system is described which two lights according to the above

Having embodiments, wherein the two lights are directly plugged together.

Furthermore, a modular lighting system is described which at least two lights after one of the previously

having embodiments described. Furthermore, the lighting system on a connector, wherein the

Connector an electrical first

Connecting terminal, which is formed according to a first plug connection of a lamp, and having an electrical second connection terminal, which is formed according to a second plug connection of a lamp. The connecting piece is connected via the first connection terminal to the second plug connection of a lamp and via the second connection terminal to the first plug connection of the other lamp. As a result, both lamps are electrically coupled together.

The lighting systems essentially enable the

aforementioned functions and advantages. By means of

described lighting systems is contributed to a modular design. In particular, therefore, as described above, a simple and quick assembly is contributed. It should be noted at this point that a combination of the two lighting systems as described above is possible. For example, several lights are provided, the

partially directly plugged together and partially electrically coupled together via a connector. The connector can, for example, in different

Lengths are pre-assembled. Depending on requirements, a distance between two lights attached thereto is determined by means of the connecting piece. For example, the distance is ensured particularly simple and secure when the connector is made essentially rigid.

For example, the connector has a substantially rigid or slightly elastic housing, which on

opposite ends of the first and the second

Connection connection has.

According to one embodiment, a housing of the

Connector adapted at least partially the luminaire housing a lamp in its outer dimensions.

This makes it possible, for example, that not only the lights, but also the connector in predetermined retaining clips, as described above, can be clipped. This contributes to a simple and inexpensive installation. In one embodiment, the connection terminals of the connector are connected by means of a cable connection. This contributes to a cost effective implementation.

For example, the connector has a plug and a coupling or socket which are connected via a cable connection.

According to one embodiment, the connector has a plurality of first connection terminals and / or second Connection connections on. In other words, the connector is a distributor. For example, the connector is star-shaped, cross-shaped or Y-shaped, so that one or more lights can be plugged 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 is plugged. This provides power to one or more lights via the connector. In other words, for example, all directly or indirectly connected to the connector

Luminaires supplied with electricity.

According to one embodiment, the power supply is in the

Connector provided. As a result, power supplies do not necessarily have to be present in the luminaires themselves.

According to a further embodiment, the connector has a flexible housing. As a result, for example, tolerances in the assembly of the lights to each other

balanced .

Furthermore, a connector for a lighting system according to the above-described embodiments will be described. The connector has at least one electrical first connection terminal, which corresponds to a first

Plug connection of a lamp described above is formed, and an electrical second connection terminal, which corresponds to a second plug connection of a top

described lamp is formed. The connector essentially allows the

aforementioned advantages and functions.

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

FIG. 1 shows a schematic, perspective view

View a modular lighting system 1 with at least two

Luminaires 2. The two luminaires 2 are identical

designed. If features of a luminaire 2 are described below, this also applies to each other

Lamp 2.

Each luminaire 2 has a luminaire housing 3, which is designed in two parts and has an upper part 4 and a lower part 5. The upper part 4 and the lower part 5 are assembled to the housing 3. The luminaire housing 3 is as

elongated tube or tube and cylindrically formed. The upper part 4 is made 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 extruded profile. The luminaire housing 3 is

optionally waterproof and dustproof. The luminaire housing 3 of a luminaire 2 has two

opposite ends 6 and 7. At the first end 6 is a first plug connection 8 and at the second end 7, a second plug connection 9 is formed. At the first

Plug connector 8 is a plug with two plug contacts 10. The second plug connector 9 is a socket with two corresponding

Female contacts. The two plug contacts 10 are as

Neutral and phase conductors formed. The situation is similar with the socket contacts. The first plug-in connection 8 serves as a power supply input and the second

Plug connection 9 as power supply output. The two plug-in connections 8 and 9 are designed for power supply with a mains voltage, for example 230 V, and can carry the entire current of a standard fuse. The two plug-in connections 8, 9 are rigidly connected to the lamp housing. In Figure 3 is a schematic, partial

Outbreak view of a light 2 shown in more detail. It can be seen that the lamp 2 has a plurality of bulbs 11 inside. The bulbs 11 are in

Embodiment LEDs. The LEDs are on one

Circuit board 12 and board arranged. The

Printed circuit board 12 is inside the lamp housing 3rd

set and arranged. For example, the

Printed circuit board 12 fixed to the lower part 5 or the upper part 4. Alternatively or additionally locked the

Printed circuit board 12 in the lamp housing 3. The two

Plug contacts 10 are electrically connected via connecting lines 13 with a power supply 14. The power supply 14 converts the voltage applied to the plug contacts 10 voltage accordingly the supply of the lighting means 11 to an operating voltage for the lighting means 11, for example 2 to 3 volts. The power supply 14 is for converting voltage

Low voltage network up to 230 volts (single-phase system) designed. Furthermore, the plug contacts 10 are connected directly to further connection lines 15 which are connected directly without the interposition of further components with the corresponding contacts of the second plug connection 9.

Thus, a power supply is looped through from the first plug-in connection 8 to the second plug-in connection 9.

The two plug-in connections 8 and 9 of a luminaire 2 are designed such that they are provided with corresponding ones

Plug-in connections 8, 9 of another lamp 2 directly

are pluggable. This will create a plug connection. This is indicated for example in FIG. In particular, the one luminaire 2 by means of the first

Plug connection 8 (plug) directly into the second

Plug connection 9 (socket) of the other lamp 2 are plugged. Thus, the two lights 2 can be plugged together in a simple manner directly electrically in series. In other words, a luminaire 2 is extended by a further luminaire 2 arranged directly next to one another. The mating of two lights 2 is force and form fit. As a result, the two lights 2 are fixed directly to each other. The two plug-in connections 8, 9 are for example crowned, while the plug contacts 10 and the socket contacts are designed to float. As a result, tolerances, for example production-related, can be compensated.

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

stuck.

For the lighting system 1 is thus only at one point a connection to a power grid necessary. The power supply of a lamp 2 is durgeschleift directly to the second connector 9 of the lamp 2 and supplies the next, infected on the lamp 2 lamp 2 with power. Alternatively, a socket is provided, for example on a ceiling or wall. From this only a connection cable for connection to a first light 2 must be installed.

As schematically illustrated, for example, in FIG. 1, the lighting system 1 has retaining clips 21. The luminaire housing 3 of the luminaires 2 are adapted in their outer shape, so in particular their outer dimensions, to the retaining brackets 21. The retaining clips 8 are

For example, standardized retaining clips according to the standard DN25. These are usually mounted on a ceiling or wall, for example in an underground car park. Subsequently, the lights 2 have just clicked into the retaining clips,

snapped or clipped. No tools or fasteners are necessary for this.

As described, the two plug-in connections 8 and 9 are designed for power supply with 220 V and can carry the entire power of a standard fuse.

As a result, the described lighting system 1 to any many lights 2 are extended to the load limit of the power grid, which are connected in series.

The luminaire 2 described allows a simple and quick installation of a modular lighting system 1. Depending on

Desirably, a plurality of lights 2 are clipped into retaining clips 21 and plugged together directly. It should be mentioned here that more than the lights 2 shown in Figures 1 and 2 can be put together. It only has to be in one place a lamp 2 to a power supply as a

Low voltage network can be connected. Farther

allow the luminaires 2 an integration of this in

existing cable installations or wiring with the predetermined retaining clips 21st

Optionally, as shown in Figure 2 on the second

Plug 9 provided a sealing element 22 as an O-ring. As a result, water and dust tightness is achieved between two assembled lights 2.

Alternatively or additionally, a further sealing element is provided on the first plug connection 8.

In the exemplary embodiment, the two plug contacts 10

or corresponding sockets designed insulated. Alternatively, the first plug-in connection 8 and the second plug-in connection 9 are multi-pole.

For example, in addition to the phase and neutral, a third pole is provided as a protective conductor. In an embodiment, not shown, the serves

Lower part 5, which is made of aluminum, as

Protective conductor. Thus, it is only necessary to provide a third pole, which at the first plug-in connection 8 with the Lower part 5 is electrically connected. The third pole of the second plug-in contact 9 is electrically coupled to the lower part 5 in the region of the second end 7. As a result, it is not necessary to cross the third pole over another

Lead wire in the lamp housing 3 from the first end 6 to the second end 7.

In further, not shown embodiments, one or more additional poles in addition to the neutral conductors and

Phase conductors may be provided at the first plug-in connection 8 and the second plug-in connection 9. For example, further power supplies or data signals can be forwarded or looped through via the further poles. In the exemplary embodiment, as described, the power supply unit is part of a lamp 2 itself. In alternative embodiments, the power supply unit may also be part of the connection coupling 17.

In alternative, not shown embodiments, the lamp housing 3 is made entirely of a transparent plastic or glass. In further alternative, not shown embodiments, at least the

Upper part 4 made of a transparent material, such as plastic or glass executed. In further, not

As shown embodiments, the lamp housing 3 is integrally formed and made of a transparent plastic or glass. In other, not shown

Embodiments, the lamp housing is two or more parts and made of one or more plastic materials. In other, not shown

Embodiments, the lower part 5 is made of a different metal material, which ensures good heat transfer. In non-illustrated embodiments, this is

Luminaire housing 3 rotatable with respect to one or both

Plug connections 8 and 9 are formed. This allows the

Beam angle of the lamp 2 can be adjusted. This is for example advantageous if the lamp 2 is already mounted on a ceiling and simply the direction of the light can be varied. FIGS. 5 to 7 show further exemplary embodiments of lighting systems 1. In each of the further lighting systems 1, several of those already described with reference to FIGS. 1 to 3 are used

described lamp 2 is used. In each of the further lighting systems 1 is at least one

Connector 18 shown. By means of the connecting pieces 18, two or more lights 2 can be mated indirectly. The connecting pieces 18 are designed in principle, a power supply of one or more connected lights 2 to other connected lights. 2

loop through. The connectors 18 may also be referred to as distributors.

In the embodiment shown in FIG

Connector 18 is an extension and has a first connection port 19 and a second

Connection terminal 20 on. At the first

Connection terminal 19 is a plug which is designed in accordance with a first plug connection 8 of a luminaire 2. The second connection terminal 20 is a socket which is designed in accordance with the second plug connection 9 of a luminaire 2. Thereby the lights 2 can be connected directly to the connector 18 and thus electrically coupled.

The connector 18 has a housing 23 and is adapted to the lights 2 in its outer shape. In other words, the diameter of the housing 23 is the

Diameter of the lights 2 adapted. Thus, that can

Connector 18 are also clipped into the predetermined retaining clips 21. This contributes to the particularly simple assembly of the lighting system 1.

The housing 23 of the connecting piece 18 is formed as a corrugated pipe. In addition to a basic stiffness is thus given a slight elasticity. As a result, for example, tolerances during assembly can be compensated for and a track of luminaires 2 arranged in a row can be influenced. However, this is not absolutely necessary.

By a predetermined length of the connecting piece 18, a distance between two lights 2 can be defined.

As a result, the illumination of a room or area can be specifically influenced.

FIG. 6 shows another lighting system 1 with three

above-described lights 2 and another

Connector 18 shown schematically. The connector 18 is formed as a T or Y-piece and has two second addition to a first connection port 19

Connection terminals 20. The two second

Connection terminals 20 are arranged on two Y-sections 24 of the connecting piece 18. The terminals 19 and 20 correspond to those described above. Analogous to the top, the three lights 2 are directly connected to the connector 18. By means of the connector 18 shown is a

Power supply of a lamp 2 (in Figure 6, the left lamp 2) passed on two other lights 2. This is another configuration option of a

Illuminant system 1 shown.

Analogously to the above, the connecting piece 18 is optionally at least partially designed as a corrugated tube and slightly elastic. Figure 7 shows schematically another lighting system 1 with four above-described lights 2 and another

Connector 18 schematically. This connecting piece 18 is a distributor block with two first connection terminals 19 and two second ones

Connection terminals 20. Thus, four lights 2 of four sides are attachable. In this case, the power supply from a lamp 2 on the other connected to the connector 18 lights 2 is ground. It should be noted at this point that the connectors described are merely exemplary and further embodiments are conceivable without departing from the idea of the present application. For example, it is conceivable that the connecting pieces 18 have a current input terminal. The power input terminal is formed, for example, according to the first plug connection of a lamp 2 and is connected to a power grid

connected. Such a connector has

only further second connection terminals 20 which are formed as a socket. To these sockets lights 2 are connected in the manner described above. Thus, no lamp 2 must be connected directly to the mains but the lights 2 are going over the

Connector 2 powered.

In further embodiments, not shown, the connecting pieces 18 have a current output terminal, via the current for other consumers or other lights

can be disconnected.

Furthermore, it is conceivable that the above-described power supply is not part of the lights 2, but in the

Connecting pieces 18 is integrated.

Figure 8 shows a lamp 2, at the end of 7 no additional light or connector 18 is connected.

For example, it is a terminal lamp 2 of a lighting system 1. On the end of an end cap 25 is attached, which closes the end 7 and the second connector 9 water and dustproof. The end cap 25 has two plug contacts for insertion into the corresponding

Socket contacts of the luminaire 2 on.

Figure 9 shows another embodiment of a lamp 2. In addition to the features already described in the

Figures 11 to 13 show further embodiments of lighting systems 1 with at least two lights 2 in schematic, perspective partial views. The lights 2 are in accordance with the above

Embodiments formed and differed in the plug-in connections 8, 9, as described below. The other embodiments contribute to a simple (disassembly of a single lamp 2, if this

For example, in a chain of several assembled lights 2 must be replaced. Figures IIA and IIB show an embodiment in a staked and assembled state of two lights. 2

The first plug connection 8 has a movable element 31, on which plug contacts 10 are arranged rigidly. The

movable member 31 is slidable with respect to

Luminaire housing 3 is arranged. In this case, a guide for the movable member 31 is provided. In the exemplary embodiment, the movable element 31 is tubular and surrounds the

Luminaire housing 3 positively, which serves as a guide. Other arrangements are conceivable. The leadership can

Be executed "over square" and prevents one

Hooking when moving. The movable element 31 can be displaced relative to a center longitudinal axis 32 towards the center of the luminaire 2 (see double arrow 38), so that the plug contacts 10 are made of the corresponding socket contacts of the second plug connection of the further luminaire 2 (left luminaire 2 in FIGS. IIA, IIB). can be pulled. The luminaire housing 3 remains

fixed position. As a result, the right lamp 2 can be disconnected from the left lamp 2, without being in a

Composite of several assembled luminaires 2 (For example, ten such lights 2 right of the lights shown in Figures IIA, IIB 2) several lights 2 must be dismantled to stake out the corresponding light 2. Thus, a single lamp 2 can be easily dismantled. It is only the movable element 31 must be withdrawn and the light then be withdrawn in a direction perpendicular to the central longitudinal axis 32. It should be noted that another lamp 2, which is connected to the right of the lamp 2 shown, also,

for example, by retracting a corresponding movable element, to be decoupled from the lamp 2 to be dismantled.

For the mating and contacting of the plug contacts 10, the movable element 31 must only be moved to the left as shown in Figure IIB in the "plug position".

The movable element 31 can in the insertion position according to Figure IIB with the other lamp 2, about the second

Lock plug connection 9. Optionally, a lock the first connector 8 and / or the second

Plug connection 9 may be provided to secure the position. Optionally, the movable member 31 may be spring-loaded, so that the movable member 31 is urged outward by a spring force from the center of the lamp.

For example, a spring element is arranged in the interior of the luminaire housing 3.

Optionally, the movable element 31 has a partial

Recess 33 in a light output side of the lamp 2 associated area. This avoids to cover bulbs in order to emit more light. Optionally, the lamp 2 may have one or more membranes, which ensures the pressure equalization when mating two lights. In particular, when moving the movable element, it may come to a pressure build-up inside the lamp, since the interior is typically sealed. This pressure is from the membrane (s)

compensated. For example, in the area of each first

Plug connection 8 a membrane installed inside the lamp 2. This contributes to a facilitated mating process.

FIG. 12 shows a further exemplary embodiment in FIG

perspective, schematic partial view. The first

Plug connection 8 has two blade contacts 33 which are inserted laterally in a direction perpendicular to the central longitudinal axis 32 of the lights 2. The second plug-in connection 9 has a relation to the lamp housing 3 to the

Longitudinal axis 32 rotatable ring 34 which has an opening 35 which is in a position so that the

Knife contacts 33 can be inserted. Subsequently, the ring 34 can be rotated, so that a lead out of the blade contacts 33 is prevented. The ring 33 may optionally be provided with a knurl for better handling.

FIG. 13 shows a further exemplary embodiment in FIG

perspective, schematic partial view. The first and second plug-in connection 8, 9 are designed so that a lateral connection in a direction perpendicular to

Longitudinal axis 32 is possible. For this purpose, the second plug connection 9 has a recess 36 with corresponding contacts, which is open at least in one direction perpendicular to the longitudinal axis, so that a contact region 37 of the first Plug connection 8 can be received in the recess 36. As a result, the lights are electrically contacted and mechanically coupled. In this case, the contacts 10 may be arranged laterally or centrally, for example, be arranged in a bore 39. The recess 36 may also be open longitudinally to the end, as shown.

The described examples according to FIGS. 12 and 13 make it possible to insert perpendicular to the longitudinal axis and thus, as described at the beginning, a simple replacement of a luminaire 2 in a group of several assembled ones

Luminaires 2 of a lighting system 1.

Furthermore, the aforementioned variants are conceivable. Thus, instead of the direct connection of the lights 2 according to FIGS. 12 and 13, corresponding connecting pieces may also be provided as mentioned above. These are then connected perpendicular to the longitudinal axis of the lights 2 for coupling this. Optionally, such connectors may also have one or more features as described with reference to the figures

Connectors 18 have or be combined with such.

The described lighting systems 1 can also be combined and / or expanded as desired. Thanks to the described lamp 2, a variety of these as needed and

Application be coupled. For example, you can

Lighting systems are generated in which lights 2 partially via connectors 18 and partially directly
