Power supply system for a lamp support

Abstract

A power supply system for producing a releasable and electrically conductive connection between a lamp support having at least one lamp and one line-like power supply element, has mutually congruent, current-conducting contact profiles. At least one contact profile has a permanent magnet and at least one contact profile has a permanent magnet and/or a ferromagnetic material. Sides of the contact profiles facing each other have a different polarity and/or attract each other. The power supply system comprises, in addition to the line-like and releasable power supply element that can be arranged on the contact profile, at least one rechargeable power supply, 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.

Claims

1. A power supply system, comprising a lamp support with a lamp, the lamp support being releasably and electrically conductively connected to a line-like power supply element by two congruent, current-conducting contact profiles, wherein a first of the two contact profiles includes a permanent magnet and a second of the two contact profiles includes a permanent magnet and/or a ferromagnetic material, wherein sides of the two contact profiles facing each other have different magnetic polarities and/or attract each other, the system further comprising a rechargeable power supply having a further contact profile with a further permanent magnet or a further ferromagnetic material, which corresponds with the first of the two contact profiles in a magnetically retentive manner.

2. The power supply system according to claim 1, wherein the second of the two contact profiles and the further contact profile are formed identical.

3. The power supply system according to claim 1, wherein the rechargeable power supply comprises a housing, the housing having a wall in which the further contact profile is embedded.

4. The power supply system according to claim 3, wherein the housing has at least one opening, in which the further contact profile is embedded.

5. The power supply system according to claim 3, wherein the second of the two contact profiles is formed in an approximately flat plane with a surface of the wall.

6. The power supply system according to claim 3, wherein the two congruent, current-conducting contact profiles are formed such that the housing of the rechargeable power supply acts as a support of the lamp support.

7. The power supply system according claim 3, wherein the housing comprises releasable connecting means by which the housing can be arranged on objects.

8. The power supply system according to claim 1, wherein the two congruent, current-conducting contact profiles and the further contact profile are formed as plugs/sockets.

9. The power supply system according to claim 1, wherein the lamp support is formed conical.

10. A power supply system, comprising a lamp support with a lamp, the lamp support having a first contact profile; a wired power supply element having a second contact profile; and a rechargeable power supply having a third contact profile, wherein the first contact profile and the second contact profile are congruent and configured to attach to one another by magnetic force while establishing an electrical connection between the lamp support and the wired power supply element, and wherein the first contact profile and the third contact profile are congruent and configured to attach to one another by magnetic force while establishing an electrical connection between the lamp support and the rechargeable power supply.

BRIEF DESCRIPTION OF THE DRAWINGS

[0010] FIG. 1 shows a lamp support and a rechargeable battery housing arranged thereon.

[0011] FIG. 1a is an enlarged view of the rechargeable battery housing in cross sectional view.

[0012] FIG. 2 a lamp support and a line-like power supply element arranged thereon.

DETAILED DESCRIPTION

[0013] As shown in FIG. 1, a power supply system comprises a conical lamp support 1 having an LED lamp and a rechargeable power supply 3, which has a contact profile 30 having a permanent magnet or a ferromagnetic material, which corresponds with the contact profile 10 of the lamp support 1 in a congruent, magnetically retentive manner.

[0014] As shown in FIG. 2, the power supply elements 2, 3 are formed to be interchangeable and, for this purpose, each have congruent and particularly advantageously identically formed contact profiles 20, 30 for the contact profile 10. The line-like power supply element 2 advantageously comprises a connection profile 21 which supports the contact profile 20. In the embodiment of the invention illustrated in FIG. 2, the line 22 is arranged on the connection profile 21 in such a way that it is oriented orthogonally to the longitudinal direction of the lamp support 1.

[0015] The power supply 3 in FIG. 1a preferably comprises a housing 31, in a wall of which the contact profile 30 is embedded, wherein the housing 31 has at least one opening 310 into which the contact profile 30 is embedded, preferably in a form-fitting manner.

[0016] 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.

[0017] 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.

[0018] 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.

[0019] In a further conceivable embodiment, the housing 31 comprises releasable connecting means, by means of which the housing 31 can be arranged on objects.

[0020] 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.

[0021] 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.
