The present disclosure relates to a power supply system for a lamp support.
Power supply systems for producing a releasable and electrically conductive connection between a lamp support having at least one lamp and one line-like power supply element are known in the prior art.
The patent application DE 101 61 709 A1 describes a current-carrying connection in the form of a (current-carrying) cable which, for example, serves to supply an LED and which is formed from a plug and a socket. Both the plug and the socket have mutually congruent contact surfaces and at least one connecting means has a permanent magnet and another connection has a ferromagnetic material, which have a different polarity and attract each other. It is provided that the magnetically connected connecting elements are current-conducting. Both connecting means can also comprise magnets which are differently poled to form a magnetic connection.
The patent application DE 10 2006 002 433 A1 describes a lighting system in which a current-conducting connection formed from magnetic contacts is provided, wherein a supply is provided at low voltage.
Furthermore, the patent application DE 101 61 709 A1 also describes a magnetic power connection, wherein the described locking device is limited primarily to a plug/socket connection.
The present disclosure provides a power supply system for a lamp support. The power supply system creates a linkage of such connections to a battery or rechargeable battery which likewise has a magnetic connection for coupling to a lamp. The two connections, battery or rechargeable battery (housing)/lamp, and cable/lamp alike form magnetic connections, which are identical and thus mutually replaceable without further adapters. The power supply system primarily serves the purpose of being able to use such a lamp support universally and easily, while allowing easy replacement of the power-supplying components depending on the intended use.
A power supply system of the aforementioned type is characterized in that the power supply system, in addition to the line-like and releasable power supply element that can be arranged on the contact profile, comprises at least one rechargeable power supply (rechargeable battery), which also has a contact profile having a permanent magnet or a ferromagnetic material, which corresponds with the contact profile in a congruent, magnetically retentive manner.
In a preferred embodiment, a lamp support having an LED is provided with a magnet which can conduct current. This makes it possible to provide the LED directly with a rechargeable battery, which also has a magnet and thus produces a current-conducting contact. It would also be possible, for example, to supply the LED with current using a rechargeable battery pack or alternatively to charge the rechargeable battery pack with the magnetic contact via a charging shell (also with magnetic contact).
The following detailed description is merely exemplary in nature and is not intended to limit the invention or the application and uses of the invention. Furthermore, there is no intention to be bound by any theory presented in the preceding background or the following detailed description.

The power supply 3 in
It is particularly advantageous to form the contact profile 30 in an approximately flat plane with the surface of the wall, so as to obtain a particularly compact and user-friendly design of the power supply element 30.
A further advantageous embodiment provides that the magnetic contact profiles 10, 30 are formed such that the housing 31 of the power supply 3 acts as a support of the lamp support 1. For this purpose, the at least one magnet of the contact profiles 10, 30 must have a sufficient adhesive force in order to hold the lamp support 1. The adhesive force should correspond to at least the weight of the lamp support.
In order to increase the adhesive force between the lamp support 10 and the contact profiles 20, 30, the contact profile connections 10, 20 and 10, 30 can additionally be designed as plugs/sockets.
In a further conceivable embodiment, the housing 31 comprises releasable connecting means, by means of which the housing 31 can be arranged on objects.
Such connecting means can be clamps, screw connections, magnetic connectors, hook and loop connectors or other positive and/or non-positive connection means. The housing 31 could thus, for example, be attached to a pair of glasses or a tool.
While the present invention has been described with reference to exemplary embodiments, it will be readily apparent to those skilled in the art that the invention is not limited to the disclosed or illustrated embodiments but, on the contrary, is intended to cover numerous other modifications, substitutions, variations and broad equivalent arrangements that are included within the spirit and scope of the following claims.
