Preferred embodiment of the invention

Figure 1 illustrates a mobile LED lamp 1 according to a first embodiment of the invention. Such mobile LED lights are sold under the name "dot-it classic" and have an annular housing portion 2, which is bounded by a bottom portion not shown in Figure 1 , on.

The bottom section, not shown in FIG. 1, has a fixation option on the side facing away from the observer, which can be, for example, an adhesive surface, a hook-and-loop surface or a magnetic surface. In this way, the mobile LED lamp 1 can be quickly fixed to a desired location temporarily or permanently.

Radially inside the annular housing section 2 of the mobile LED lamp 1 there is a reflector 4, in which light-emitting diodes 6a, b, c are accommodated at an angle of 120 °. The LEDs are preferably so designed that these generate white light, so that for example the function of a flashlight can be implemented by the mobile LED light at much more compact dimensions. Radially within the LEDs 6a, b, c is an actuating portion, preferably in the form of a protrusion 8 _» provided by the reflector 4 can be pushed into the annular housing portion 2 to the bottom portion, not shown. About the protrusion 8, a button is actuated, which goes back to its non-switched state after actuation, wherein the button is part of an actuation control circuit via which a drive circuit for the LEDs 6a, b, c is actuated.

The front surface of the reflector 4 is adjacent to the front surface of the annular housing portion 2, which faces the viewer in Figure 1. Between the bottom section shown in FIG. 1 and the wall of the annular housing section 2 facing the viewer, three magnetic devices 10a, b, c are provided at an angle of 120 degrees to one another about the reflector 4 adjacent to the reflector 4. The magnet devices 10 a, b, c are formed in such a manner that a magnetic field is present outside the outer circumference 12 of the annular housing section 2. Two of the magnets 10a, b, c have mutually different magnetic poles.

The magnetic device 10a, 10b, 10c, are located in the annular housing portion and can, for example, at the bottom portion or at any inner wall portion of the annular housing portion second be arranged. The attachment can be made for example by gluing.

Figure 2 shows an arrangement of 5 mobile LED lights 1, 20, 30, 40, 50, according to the first embodiment. It is assumed that the magnetic device 10a forms a north pole and the magnetic device 10b forms a south pole. The magnet device 20a of the mobile LED lamp 20 is again a north pole, while the magnet device 20b of the mobile LED lamp 20 is a south pole. The magnet device 20b of the mobile LED lamp 20 is a south pole, and the magnet device 40a of the mobile LED lamp 50 is a north pole. The magnet device 30a of the mobile LED lamp 30 is a north pole. As a result, three other mobile LED lights 1, 30, 40 can be held on the mobile LED lamp 20, and the magnetic devices 10b, 20a, the magnetic devices 20b, 30a and the magnetic devices 20c, 40a are magnetically connected with each other.

As can be seen from FIG. 2, the mobile LED lights 10, 30, 40 can be arranged around the mobile LED light 20 and can be magnetically connected to it. In this way, figures or symbols can be generated by means of mobile LED lights and can realize higher luminous flux.

Also shown in Figure 2 is a mobile LED lamp 50 which is magnetically attached to the magnet means 30b of the mobile LED lamp 30 via the magnet means 50a. This emphasizes that with the three magnetic devices 10a, b, c of a mobile LED lamp. 1 According to the first embodiment of the invention, larger luminous surfaces can be put together on the basis of mobile LED luminaires. Such lighting surfaces are easily dismantled again in their individual mobile LED lights. Thus, in the short term, higher requirements for lighting with mobile LED lights can be taken into account.

FIG. 3 shows a further application of the mobile LED luminaires in arrangements of 4 luminaires according to the first exemplary embodiment. The mobile LED lights 1, 20, 30, 40, are grouped into group 14. Identical groups 16 and 18 of mobile LED lights are arranged adjacent to the group 14. In this case, the mobile LED lamp 40 of the group 16 enters between the mobile LED lights 1, 30 of the group 14 and enters mobile LED lamp 1 of the group 18 between the mobile LED lights 30, 40 in this way, with a small space requirement high light intensity can be implemented. The respective groups, 14, 16, 18 are preferably not magnetically connected to one another.

Figure 4 shows a modification of the mobile LED lamp according to the first embodiment in Figures 1 to 3, the magnetic devices 10a, b, c were provided at an angle of 120 ° to each other adjacent to the annular housing portion or on this. However, the present invention is not limited to the arrangement of three magnetic devices. A connection between mobile LED lights can already be made when a magnetic device to a mobile LED lamp and another magnetic device with different magnetic polarity on a other mobile LED lights are provided. The disadvantage is that different mobile LED lights must be formed.

In order to use identical mobile LED lights, it is advantageous at least two fastening devices, i. to use in the first embodiment, two magnetic devices with different polarity. However, more than 3 magnetic devices can also be used.

For example, it is conceivable in FIG. 3 that six magnet devices are provided adjacent to the outer circumference of a mobile LED luminaire.

In FIG. 4, two magnetic devices arranged at an angle of 90 ° are used, by means of which four mobile LED lamps 22, 32, 42, 52 can be combined to form a group. It is preferable that, on each of the mobile LED lights 22, 32, 42, 52, two other magnetic devices are formed in the circumferential direction at an angle of 90 ° to each other, whereby a regular large area can be formed with these mobile LED lights.

Figures 5 and 6 relate to the second embodiment or a modification thereof.

In an LED lamp 60 according to the second embodiment shown in Figure 5, the housing 62 is elongated and is also a longitudinally shaped reflector 64 with three LEDs 66a, b, c in this reflector 64. The actuation takes place Also, by impressing the reflector 64 with respect to the housing 62. Adjacent to the outer edges 68, 69 provided in the longitudinal direction A, magnetic devices 70a, 70b are formed with opposite polarity on the mobile LED lamp 60. Such mobile LED lights 60 can be magnetically connected to each other in the longitudinal direction and thus can be formed from these light strips. If the distance between the outer edge 68 and the center of the light emitting diode 66a is referred to as a and the distance between the centers of the light emitting diodes 66a and 66b and between the light emitting diodes 66b and 66c as small b, and the distance between the center of the light emitting diode 66 c and the outer edge 69 is referred to as a, so at a choice of the distance b equal to twice the distance a, a regular arrangement of light emitting diodes in a plurality of mutually magnetically coupled mobile LED lights are provided.

FIG. 6 shows a modification of the second exemplary embodiment shown in FIG. The mobile LED lamp 80 in this modification differs from the mobile LED lamp 60 of FIG. 5 only in the additional magnet devices 82a, 82b and 84a, 84b provided adjacent to the longitudinal sides 86, 88 with respect to the housing 62 are. The magnetic devices 82a, 82b, just like the magnetic devices 84a, 84b, have mutually different magnetic poles, so that adjacent to the longitudinal sides 86, 88 further mobile LED lights can be magnetically connected to the mobile LED light 80. The present invention is not limited to the magnetic connection between the mobile LED lights, but also any mechanical connection between them may be made, for example by connectors.

In mobile LED lights according to the third embodiment, which have not been reproduced in the drawings, electrical connectors may be provided between the mobile LED lights instead of the magnetic means. For example, instead of a magnetic device that represents a north pole, a plug can be provided and a socket instead of a magnetic device that represents a south pole.

Alternatively, only sockets can be provided on the mobile LED lights, in the double plug, at the opposite end portions each have a plug are provided, can be introduced. In this way, the mechanical connection between the mobile LED lights can be produced.

A mechanical connection by means of plugs and sockets also has the advantage that the control electronics of all the LEDs of the mobile LED light can be switched via this mechanical connection.

An example of the electronic circuit with voltage supply 90, actuation circuit 92 and drive circuit 94 for light-emitting diodes 96a, 96b and 96c is shown in FIG. These light emitting diodes may be the light emitting diodes 6a, b, c of the first embodiment or the light emitting diodes 66a, b, c of the second embodiment. In the actuating circuit 92, a button 98 is provided, via the actuation of the drive circuit 92 is switchable in a defined state, that can either be turned on or off. Between the actuating circuit 92 and the drive circuit 94 connection contacts 100 are provided, via which the mobile LED light of the third embodiment can be connected via described socket-plug arrangements with structurally identical further mobile LED lights.

However, the third embodiment is not limited to a pair of connection contacts, but as in the first and second embodiments, two, three or more pairs of connection contacts 100 may be provided to make electrical connection with adjacent, preferably identical, mobile LED lights.

In an electrical connection between two circuits for mobile LED lights shown in Fig. 7 according to the third embodiment via connection contacts 100, the state of the driving circuits of the LEDs is preferably after connecting the contacts 100 and the one-time operation of the button 98, but more preferably immediately after connecting the contacts 100, synchronized. Thus, via one of the actuating circuits 92 of the mobile LED lights, the electrically connected LED lights can be switched.

The invention is not limited to that mobile LED lights 1 of the first embodiment or mobile LED lights 60 of the second embodiment are each connected only with identical mobile LED lights. It is also mobile LED lights with different design can be connected together, as long as the connection concept is compatible with each other. For example, a plurality of mobile LED lights 60 can be magnetically attached to a mobile LED light 1 in order to implement a desired lighting concept.
