Description

The present invention relates to a lamp with a lamp body on which an illuminant and a first electrical connection are provided, and a power pack with a second electrical connection which can be releasably connected or is connected to the first electrical connection.

Lamps are known from the prior art which can be supplied with electrical energy via a stationary electrical network. The lamps mentioned have a lamp body on which a light source, for example an LED, and a first electrical connection are provided. In addition, the lamp has a power supply unit, which has a second electrical connection, which in turn can be releasably connected or connected to the first electrical connection, in order to be able to supply the illuminant with electrical energy via the power supply unit that is connected or can be connected to a power supply system and the two electrical connections that are connected to one another. The mains unit, which can be detached from the lamp body, has the advantage that it can be kept or stowed away separately from the lamp body, as a result of which particularly flexible handling is possible. A defective power supply can also be easily replaced with a functional power supply, for example.

In addition, lamps are known, in particular flashlights, which also have a lamp body on which a lamp and an electrical connection are provided, via which the lamp can be supplied with electrical energy, with the known flashlights having a fastening arrangement, in particular a receptacle, to which an electrical energy storage device, such as one or more batteries, is detachably fastened, supplying energy to the lamp.

From the DE 10 2007 050 738 A1 a lamp is known which has a lamp body and a first electrical connection. Either a second electrical connection of a power pack or an electrical energy store can be connected to the first electrical connection. In order to be able to connect the electrical energy storage device, an additional housing that can be detachably fastened to the lamp body is provided with a fastening arrangement in the form of a receptacle in which the electrical energy storage device can be accommodated.

It is an object of the present invention to further develop a lamp of the generic type with a lamp body, a power pack that can be connected to it and a fastening arrangement for fastening an energy storage device in such a way that it has a particularly simple structure and ensures particularly flexible and simple handling.

This object is achieved by the features specified in patent claim 1. Advantageous embodiments of the invention are the subject matter of the dependent claims.

The lamp according to the invention, which is preferably designed as a portable lamp, has a lamp body with a luminous section. The lamp body is preferably essentially made of plastic. A lighting means is provided on the lighting section, the lighting means being an LED in a particularly preferred embodiment variant. In addition, a first electrical connection is provided on the lighting section, which can be designed, for example, in the manner of a plug-in part, ie, for example, as a plug or sleeve. In addition, the lamp has a power pack assigned to the lamp body. The power pack is preferably designed in such a way that it is able to reduce a mains voltage to 18 to 21 volts. The power pack itself has a second electrical connection, which can be releasably connected or is connected to the first electrical connection on the lighting section, so that electrical energy from a mains supply can be supplied to the light source via the power pack and the two electrical connections in order to light it up. In this case, an interrupter switch is preferably also arranged on the lamp body, which switch enables the lighting means to be switched on and off. The use or handling of the lamp is restricted by the power pack, especially since it can only be operated in the vicinity of a corresponding connection to a mains power supply. In order to overcome this disadvantage, the lamp has fastening arrangements to which electrical energy stores, preferably rechargeable energy stores or accumulators, can be detachably fastened while the light source is supplied with energy. Consequently, the lamp according to the invention can use both an existing mains power supply via the power pack and the two electrical connections and can also be operated independently of a mains power supply via the electrical energy store, which ensures particularly flexible handling and use of the lamp. The fastening arrangements mentioned are preferably to physical structures that enable a positive and/or non-positive attachment of electrical energy storage devices to the lamp, with the electrical energy storage device preferably having a matching fastening arrangement for this purpose, which in turn can also consist of a corresponding physical structure of the electrical energy storage device. The lamp has at least two detachably and optionally individually fastened or fastened connecting parts on which fastening arrangements are provided, to which in turn the aforementioned electrical energy store can be detachably fastened while supplying energy to the lamp. Thanks to the connecting part that is detachably fastened to the lighting section and has the fastening arrangement provided thereon, the lamp enables the connecting part and therefore also the respective fastening arrangement for the electrical energy store to be replaced, which enables the lamp to be adapted to different energy stores without the lamp body itself having to be changed. Consequently, when using different connecting parts with correspondingly different fastening arrangements, different electrical energy stores can also be used by other devices and tools, which makes the lamp particularly interesting for craftsmen with various battery-operated tools. For this reason, the at least two connecting parts that can be selectively fastened to the lamp body have fastening arrangements that differ from one another for fastening different or deviating energy stores. In principle, one can also speak of a lamp set that has the at least two connecting parts, the lamp body and the power pack. As already indicated, the exchange of the at least two connecting parts allows the use of different energy storage devices for the lamp, without the lamp body itself would have to be exchanged, so that one can speak of a particularly flexible use. Furthermore, there is a first assembly direction in which each connecting part can be guided or forcibly guided into a fastening position on the lighting section, a second assembly direction in which each electrical energy storage device can be guided or forcibly guided into a fastening position on one respective connecting part, and a second release direction opposite to the second assembly direction, in which each energy storage device can be released from the fastening position on one respective connecting part. In order to bring about such guidance or forced guidance of the connecting part in the first assembly direction, a receptacle or depression can be provided in the luminous section, for example, into which the connecting part can be inserted with lateral guidance. The second assembly direction, in which an electrical energy store can be guided or forced into a fastening position on each connecting part, extends transversely or at right angles to the first assembly direction. As a result, there is also a first release direction, opposite the first assembly direction, in which the connecting part can be released from the fastening position, and the second release direction, opposite the second assembly direction, in which each electrical energy storage device can be released from the fastening position on the associated connecting part. The advantage here is that when the energy store is released in the second release direction, no release force or at most a small release force acts on the connection part in the first release direction, so that there is no unintentional release or unfavorable stress on the connection part. If, on the other hand, the energy store together with the associated connecting part is to be detached from the luminous section, the operator can, for example, exert a releasing force on the energy store in the first release direction in order to release the energy store together with the To solve connecting part of the lamp body. Thanks to the mentioned alignment of the first and second assembly direction or the first and second release direction to each other, the handling of the lamp, in particular when changing the energy store, is significantly simplified. In addition, the lamp body has a support section and the lighting section, which can be pivoted about a pivot axis relative to the support section. This structure enables a particularly flexible use of the lamp, in order to ensure different working areas for a lamp supported via the support section by means of a corresponding position of the luminous section relative to the support section. In order to achieve a particularly advantageous handling, the second release direction points to the side of the luminous section facing away from the pivot axis, in order to enable a particularly simple exchange of the respective energy store.

In principle, the connecting parts could be fastened to the lamp body in a plurality of predetermined fastening positions relative to the lamp body, but in an advantageous embodiment of the lamp according to the invention the connecting parts and the lamp body are matched to one another in such a way that the connecting parts can be fastened or are fastened to the lighting section in only one predetermined fastening position relative to the lamp body.

In principle, in the lamp according to the invention, both the power pack and the electrical energy storage device could be connected at the same time, so that, for example, a rechargeable energy storage device could be recharged via the mains or the power pack. The problem, however, is that the manufacturers of the various energy storage devices usually have their own or specific protective electronics for charging the rechargeable Prescribe energy storage, which is usually only provided in the specific chargers from the manufacturer. This would mean that the inventive Lamp would have to provide or include the protection electronics for each of the energy storage devices to be used. Appropriate protective electronics could be integrated into the connecting parts, for example. However, this would significantly increase the design effort for the lamp. For this reason, in a particularly advantageous embodiment of the lamp according to the invention, the first electrical connection is at least partially covered by the connecting part when the connecting part is in a fastening position on the lighting section. The previously mentioned specific protective electronics for the various energy stores can be dispensed with in the lamp according to the invention, especially since the covering of the first electrical connection by the connecting part in its fastening position is able to largely prevent a connection of the second electrical connection of the power supply unit to the first electrical connection of the lighting section. In this case, it is preferred if the first electrical connection is covered by the connection part in a fastening position of the connection part on the luminous section for the second electrical connection so that it is not possible to connect the power supply unit when the connection part is attached. In addition, it is particularly preferred in this embodiment if the second electrical connection, which has been detached from the first electrical connection, cannot be connected to the first electrical connection in the fastening position of the connecting part.

In order to also in the reverse case, namely when the first electrical connection is already connected to the second electrical connection, to prevent simultaneous attachment of the energy storage device and thus to make a specific protection electronics for the various energy storage devices unnecessary, is with the second electrical connection connected to the first electrical connection is arranged on the luminous section in such a way that the connecting part cannot be fastened to the luminous section or cannot be brought into a fastening position on the luminous section.

In a further advantageous embodiment of the lamp according to the invention, the illuminant can be supplied with energy from the electrical energy store in a fastening position of each connecting part on the lighting section via the connecting part interacting with the first electrical connection. In this embodiment, each connecting part that is releasably attached to the lighting section uses the first electrical connection that is present in any case, in order to use it to supply the lighting means with electrical energy. This ensures a particularly simple structure, especially since no additional lines that ensure the energy or power supply of the lighting means via the energy storage device have to be provided in the lighting section. A particularly simple structure is achieved in this way.

According to a further advantageous embodiment of the lamp according to the invention, each connecting part has a third electrical connection which is connected to the first electrical connection in the fastening position of each connecting part on the lamp body. Furthermore, it is preferred in this embodiment if each connecting part also has a fourth electrical connection which is connected to the third electrical connection and which can be connected to the respective electrical energy store. By appropriately dimensioning and arranging the fourth electrical connection, there is also an adaptation to the respective electrical energy store. Moreover, the fourth electrical connection is preferable designed in such a way that it cannot be connected to the second electrical connection of the power supply unit. In other words, the fourth electrical connection preferably has a size, shape and/or arrangement that differs from the first electrical connection on the luminous section in order to achieve this effect.

In a further advantageous embodiment of the lamp according to the invention, the fastening arrangement of each connecting part has a guide groove for the energy store, which groove extends in the second mounting direction. The guide groove is preferably an undercut guide groove, ie, for example, a guide groove with a dovetail-shaped cross section. The undercut guide groove allows each energy storage device to be installed or inserted into the guide groove in the second installation direction while at the same time supporting the energy storage device within the guide groove transversely to the second installation direction.

In a further preferred embodiment of the lamp according to the invention, the first electrical connection is a first plug-in part, for example a plug or a socket, and the second electrical connection is a second plug-in part, for example a socket or a plug, of a detachable plug connection. In this case, the second plug-in part can preferably be plugged together with the first plug-in part in the aforementioned first assembly direction.

In a further particularly preferred embodiment of the lamp according to the invention, the aforementioned third electrical connection on each connecting part is designed as a third plug-in part which can be plugged together with the first plug-in part, it being preferred in this embodiment if the third plug-in part essentially corresponds to the second plug-in part of the power supply unit.

In order to further simplify the handling of the lamp, in a further advantageous embodiment of the lamp according to the invention, each connecting part can be fastened or is fastened to the luminous section in a latching manner. It is preferred if an elastic locking means is provided on the luminous section or each connecting part and a locking means which interacts with the elastic locking means is provided on each connecting part or luminous section. The elastic latching means can be a latching tongue, for example, while the second-mentioned latching means can be formed, for example, by a latching projection or a latching recess. In this case, however, each connecting part does not have to be fastened or fastened exclusively in a latching manner to the luminous section. Rather, in an advantageous embodiment, the locking attachment to the luminous section can precede the non-positive attachment of each connecting part to the luminous section, preferably by a screw connection, so that the locking attachment initially ensures a pre-fixation that simplifies the final fixing by a screw connection or the like.

In the previously described embodiments of the lamp according to the invention, the lamp or the lamp set does not necessarily have to have the electrical energy store, which can be detachably fastened to the fastening arrangement. In a further advantageous embodiment of the lamp according to the invention, however, the lamp or the lamp set also has the aforementioned electrical energy store. It is preferred here if it is a rechargeable electrical energy store or accumulator. At this In an embodiment of the lamp according to the invention, the first electrical connection is preferably at least partially covered by the energy store itself in a fastening position of the electrical energy store on the fastening arrangement or is inaccessible to the second electrical connection. The advantage of this embodiment variant has already been explained above and consists in the fact that the power pack can only be connected to the lamp with difficulty or not at all at the same time as the electrical energy store, so that specific protective electronics for the respective energy store can be dispensed with. It is also preferred in this embodiment if the second electrical connection, which is detached from the first electrical connection, cannot be connected to the first electrical connection in the fastening position of the energy store on the fastening arrangement.

Figures 1 to 7 show a first embodiment of a portable lamp 2. In the figures, the opposite longitudinal directions 4, 6, the opposite width directions 8, 10 and the opposite vertical directions 12, 14 of the lamp 2 are indicated by corresponding arrows. The lamp 2 has a lamp body 16 . The lamp body 16 is composed essentially of a support section 18 and a lighting section 20 .

The support section 18 serves to support or otherwise arrange the lamp body 16 on the ground or an object in the vicinity. The support section 18 is essentially U-shaped and has two spaced apart widthwise 8 , 10 and lengthwise 4 , 6 extending Longitudinal struts 22, of which in 1 only one is shown, the two longitudinal struts 22, 22 being connected to one another at their ends pointing in the longitudinal direction 6 via a transverse strut 24 extending in the width directions 8, 10, in order to be essentially U-shaped. In their end region pointing in the longitudinal direction 4, the two longitudinal struts 22, 22 each have a projection 26 that extends upwards in the vertical direction 12, of which in turn only one in 1 is shown. The two projections 26, 26 rise above the respective longitudinal strut 22 in the vertical direction 12.

The lighting portion 20 of the lamp body 16 is movably arranged on the support portion 18 of the lamp body 16 so that the lighting portion 20 can be moved relative to the support portion 18 . In the illustrated embodiment, the luminous section 20 can be pivoted relative to the support section 18 about a pivot axis 28 extending in the width directions 8 , 10 . The pivot axis 28 extends between the two opposite projections 26, 26 of the longitudinal struts 22, 22 in the width direction 8, 10, the lighting section 20 being arranged on the projections 26, 26 such that it can pivot such that the pivot axis 28 is arranged in the vertical direction 12 above the longitudinal struts 22, 22 and/or the transverse strut 24. The lighting section 20 is composed essentially of a housing 30 , a lighting means 32 arranged in the housing 30 and a transparent cover 34 for covering the lighting means 32 arranged in the housing 30 . The cover 34 thus forms the front side 36 of the lamp 2 , while the housing 30 forms the rear side 38 of the lamp 2 facing away from the front side 36 .

In the housing 30, more specifically in the of A recess or receptacle 40 is formed on the rear side 38 of the lamp 2 formed on the housing 30 . The flanks delimiting the depression 40 in the width directions 8, 10 also each have a latching means 42, which is designed here as a latching depression. The latching means 42 in the form of the latching depressions interact with the elastic latching means of the connecting parts, which will be described in more detail later. In addition, a first electrical connection 44 is provided on the lamp body 16 or the housing 30 of the lighting section 20 . In the illustrated embodiment, the first electrical connection 44 is formed by a first plug-in part 46, here in the form of a socket, which forms a plug-in connection together with the second electrical connection, which will be described in more detail later. An electrical line 48 is also indicated in the figures, which connects the first electrical connection 44 to the light source 32, the light source 32 preferably being in the form of an LED.

In addition, the lamp 2 has a power pack 50 , the power pack 50 being connected to a second electrical connection 54 via an electrical line 52 . The power pack 50 can be connected to a power grid via a further electrical line 56 in order to ensure that the lamp 2 is supplied with energy via the power grid and the power pack 50 . For this purpose, the second electrical connection 54 is designed as a second plug-in part 58, with the first plug-in part 46 in the form of a socket and the second plug-in part 58 in the form of a plug being able to form a detachable plug-in connection with one another, as is shown in 4 is shown. The second plug-in part 58 can preferably be plugged together with the first plug-in part 46 in a first assembly direction 60, with the first assembly direction 60 being discussed in more detail later. Generally speaking is the second electrical connection 54 can be releasably connected to the first electrical connection 44 or is connected, wherein 1 the solved power pack 50 shows while 4 the connected power supply 50 shows.

The lamp 2 also has a first fastening arrangement 62 to which an electrical energy store 64, preferably a rechargeable electrical energy store or accumulator, can be detachably fastened with the illuminant 32 being supplied with energy. However, the first fastening arrangement 62 is not arranged on the luminous section 20 or the housing 30 thereof, but rather on a first connecting part 66 which can be detachably fastened or fastened to the lamp body 16 , here the housing 30 of the luminous section 20 . So shows 1 the detached from the housing 30 of the lamp body 16 first connecting part 66, while in the Figures 5 and 7 the first connector 66 attached to the housing 30 is shown.

From the Figures 1 to 3 It can also be seen that the lamp 2 in the design shown has at least two connecting parts that can be attached to the lamp body 16, namely the first connecting part 66 and the second connecting part 68. The two connection parts 66, 68 are essentially structured, whereby these fastening arrangements 62 have, which is why the fastening arrangement of the first connecting part is based on the first time 62 and the fastening arrangement of the second connecting part 68 is referred to as the second fastening arrangement 70. The fastening arrangements 62, 70, which differ from one another, serve to fasten different electrical energy stores or accumulators, depending on the electrical energy store to be used the appropriate connecting part 66, 68 with the corresponding fastening arrangement 62, 70 can be selected.

The located on the respective back of the connecting parts 66 and 68 fastening assemblies 62, 70 are in the Figures 2 and 3 shown again. The first fastening arrangement 62 essentially has an undercut guide groove 72 in the form of a dovetail guide, into which a correspondingly dovetail-shaped projection on the energy store 64 ( 6 ) can be introduced. The guide groove 74 of the second fastening arrangement 70 on the second connecting part 68 is also designed as an undercut guide groove 74, but is not dovetail-shaped and also has different dimensions than the previously mentioned guide groove 72 of the first fastening arrangement 62. The guide groove 74 of the second fastening arrangement 70 is therefore designed to accommodate a different electrical energy storage device.

Otherwise, the two connecting parts 66, 68 are designed to be essentially identical. Thus, on the front side of the respective connecting part 66, 68 facing away from the respective fastening arrangement 62, 70, a guide section 76 is formed, which is designed here as a peripheral wall and can be introduced into the receptacle 40 of the lamp body 16 with the respective connecting part 66, 68 being guided. It can also be seen that elastic latching means 78 are provided on the guide section 76, which interact with the aforementioned latching means 42 in the form of latching depressions when the respective connecting part 66, 68 is fastened to the lamp body 16, with the elastic latching means 78 being designed as latching projections for this purpose, which in turn are arranged on elastic tongues. As a result, both connecting parts 66, 68 can be fastened or are fastened to the luminous section 20 of the lamp body 16 in a latching manner.

In addition, the two connecting parts 66, 68 each have a third electrical connection 80 which, like the second electrical connection 54, can be connected to the first electrical connection 44. The third electrical connection 80 is embodied as a third plug-in part 82, which can be plugged together with the first plug-in part 46 in the form of the socket and moreover essentially corresponds to the aforementioned second plug-in part 58, so that the third plug-in part 82 is also embodied in the manner of a plug. In addition, the two connecting parts 66, 68 each have a fourth electrical connection 84, which is connected to the respective third electrical connection 80 within the connecting part 66, 68 and can be connected to the associated electrical energy store, which is fastened to the respective fastening arrangement 62, 70. How from the Figures 1 and 2 1 and 3, the fourth electrical connections 84 can also be adapted in terms of their dimensioning, embodiment variant and arrangement to the electrical energy store to be used in each case.

Other features of the lamp 2 and its operation with reference to the Figures 1 to 7 described.

4 shows the lamp 2 during normal mains operation via the power pack 50, the second electrical connection 54 being connected to the first electrical connection 44 for this purpose in order to supply the lighting means 32 with energy or current. The power pack 50 is preferably a power pack which reduces the mains voltage to between 18 and 21 volts. How out 4 As can be seen, the second electrical connection 54 of the power supply unit 50, which is connected to the first electrical connection 44, is arranged on the lamp body 16 or the housing 30 of the lighting section 20 in such a way that neither of the two connecting parts 66, 68 can be inserted into the receptacle 40 in order to attach the connecting part 66 or 68 to the lamp body 16. In other words, when connected to the first electrical connection 44, the second electrical connection 54 is arranged in such a way that neither of the two connection parts 66 or 68 can be brought into the fastening position intended for them on the lamp body 16. This has the decisive advantage that simultaneous operation via the power pack 50 on the one hand and an electrical energy storage device or accumulator on the other hand is ruled out, especially since the electrical energy storage device cannot be attached to the lamp 2 . By excluding simultaneous operation, recharging of the rechargeable energy store via the power pack 50 is also excluded, so that the lamp 2 or the connecting part 66; 68 can do without complex protective electronics, which is prescribed by the manufacturer of the electrical energy storage. This significantly simplifies the construction of the lamp 2 .

Conversely, the advantages described above apply accordingly. If the second electrical connection 54 is detached from the first electrical connection 44, one of the two connecting parts 66 or 68 can be fastened to the lamp body 16, this being explained below by way of example using the first connecting part 66 and with reference to FIG Figures 5 to 7 is described.

The first connecting part 66 can be inserted into the receptacle 40 in the housing 30 in the first assembly direction 60 already mentioned above in order to move into the in figure 5 shown predetermined mounting position on the lamp body 16 to arrive. In this case, the first connecting part 66 is forcibly guided via its guide section 76, which is supported on the flanks of the receptacle 40, without the connecting part 66 being able to rotate in the process. Receptacle 40, connecting part 66 and first and third electrical connection 44, 80 are also dimensioned and designed in such a way that first connecting part 66 can be fastened or fastened to lamp body 16 in only one predetermined fastening position relative to lamp body 16, with this predetermined fastening position relative to lamp body 16 being in the Figures 5 and 7 is shown.

When the first connecting part 66 has the predetermined attachment position figure 5 reached, the elastic latching means 78 latch with the latching means 42, so that one can also speak of a latching attachment of the connecting part 66 to the lamp body 16. Although not shown in more detail, a further attachment can be provided in addition to the latching attachment, such as a non-positive attachment in the form of a screw connection, in order to ensure a particularly secure hold of the connecting part 66 on the lamp body 16 .

An advantage of the first embodiment described is that the first electrical connection 44 is covered by the connection part 66 in the fastening position of the connection part 66 on the lamp body 16 at least partially - in this case completely - inaccessible to the second electrical connection 54, so that the first electrical connection 44 released second electrical connection 54 of the power supply 50 in the fastening position of the connecting part 66 can no longer be connected to the first electrical connection 44, which in turn excludes parallel mains and battery operation. As already explained above, this makes special protective electronics unnecessary for each of the different electrical energy stores to be used and thus simplifies the structure of the lamp 2.

Thanks to the special arrangement of the respective connecting part 66, 68 in its fastening position on the lamp body 16, it is not only prevented that the power supply unit 50 can also be connected via the second electrical connection 54, but rather the light source 32 can be supplied with energy from the electrical energy store 64 in the fastening position of the at least one connecting part 66, 68 on the lamp body 16 via the connecting part 66 or 68 interacting with the first electrical connection 44. This is due to the fact that when the respective connecting part 66 , 68 is inserted into the receptacle 40 in the first assembly direction 60 , the third electrical connection 80 is also connected to the first electrical connection 44 in the first assembly direction 60 . Consequently, the light source 32 can subsequently be supplied with the energy or current of an energy store via the fourth electrical connection 84, the third electrical connection 80, the first electrical connection 44 and the electrical line 48, with the fourth electrical connection 84 being shaped or arranged in such a way that it can be connected to the specific electrical energy store but not to the second electrical connection 54.

In order to supply the above-described Lighting means 32 via the electrical energy store 64, the energy store 64 is inserted in a second assembly direction 86 into the guide groove 72 until it reaches the in 7 mounting position shown on the connecting part 66 is reached. For the detachable attachment of the electrical energy store 64 to the connecting part 66, the latching devices usually provided on such energy stores 64 can be used, for example, which can interact with the associated connecting part. The energy store 64 is also positively guided in the second assembly direction 86 , the second assembly direction 86 extending transversely, here at right angles, to the first assembly direction 60 . This constellation has the advantage, among other things, that the energy store 64 can later also be pulled transversely to the first assembly direction 60 in the second release direction 88, which is opposite to the second assembly direction 86, without force being applied to the connecting part 66 in the first release direction 90, which is opposite to the first assembly direction 60. This is advantageous, for example, when two identical electrical energy stores 64, 64 are to be replaced without the connecting part 66, which can be used equally for both energy stores 64, 64, having to be detached from the lamp body 16.

8 shows a second embodiment of a lamp 2, which essentially corresponds to the first embodiment according to the preceding figures, so that only the differences are discussed below, the same reference numbers are used for the same or similar parts and the previous description otherwise applies accordingly.

According to the second embodiment 8 the lamp body 16 has the first electrical connection 44 and a supplementary first electrical connection 92, with the first electrical connection 44 primarily being intended here to connect to the third electrical connection 80 of the respective connecting part 66, 68, while the supplementary first electrical connection 92 is intended to be used to connect to the second electrical connection 54 of the power supply unit 50. In the second embodiment, the supplementary first electrical connection 92 is at least partially covered by the energy storage device 64 or is inaccessible to the second electrical connection 54 when the electrical energy storage device 64 is in the fastening position on the fastening arrangement 62 or 70 of the first or second connection part 66, 68. Consequently, the second electrical connection 54 detached from the supplementary first electrical connection 92 cannot be connected to the supplementary first electrical connection 92 in the fastening position of the energy store 64, which in turn rules out parallel operation via the power grid and energy store. The same applies in the event that the second electrical connection 54 is connected to the supplementary first electrical connection 92, as a result of which the electrical energy store 64 is not included in the in 8 Mounting position shown can be transferred. The same also applies to the respective connecting part 66 or 68, which, when the energy store 64 is arranged on it, does not fit into the in 8 Mounting position shown can be transferred within the receptacle 40 when the second electrical connection 54 is connected to the supplementary first electrical connection 90.

Finally, it should also be mentioned that in both embodiments the pivot axis 28, which is higher than the longitudinal struts 22, has the advantage that the luminous section 20 of the lamp body 16 can be pivoted relatively far in the direction of the support section 18. without the electrical energy store 64 arranged on the luminous section 20 colliding with the support section 18 or a base on which the support section 18 is supported in the height direction 14 . With regard to handling, it has also proven to be advantageous if the aforementioned second release direction 88 for the electrical energy store 64 points to the side of the luminous section 20 of the lamp body 16 facing away from the pivot axis 28 and/or the second assembly direction 86 points in the direction of the pivot axis 28, in order to enable a particularly simple replacement of the respective energy store 64.
