Abstract

An arrangement for lighting an object having a first, non-mobile device (1) and a second, movable device (2). The first device (1) has at least one lighting unit (3) and at least one 5 rechargeable accumulator (4). The at least one accumulator (4) is connected to the at least one lighting unit (3) in order to be able to provide this with power. The second device (2) has a charger (5) for charging the rechargeable accumulator (4) of the first device.

Claims

1. Arrangement for lighting an object, comprising:

a first device (1) for lighting an object, which is permanently bound to a fixed location, comprising at least one lighting unit (3) and at least one rechargeable accumulator (4) which is connected to the at least one lighting unit (3) in order to be able to provide this with power, and

a second, movable device (2) which comprises a charger (6) for charging the rechargeable accumulator (4) of the first device.

2. Arrangement according to claim 1, wherein the first device comprises two contact points (9) on one outer side, each contact point (9) of which is connected to a different pole (7) of the at least one rechargeable accumulator and wherein the second device is equipped to connect the charger (6) to the contact points (9) in a suitable manner.

3. Arrangement according to claim 2, wherein the first device furthermore comprises a rectifier (11) that is installed between one of the two contact points (9) and the pole (7) of the rechargeable accumulator (4) connected thereto.

4. Arrangement according to claim 1, wherein the first device (1) furthermore comprises a first coil (12) that is connected to the rechargeable accumulator (4), for generating a charge current if a fluctuating magnetic field is applied, and the charger (6) of the second device (2) has a generator (14) for generating a fluctuating, electric current and the second device (2) furthermore has a second coil (13) that is connected to the generator (14) so as, if positioned in the vicinity of the first device (1), to generate a fluctuating magnetic field for generation of the charge current in the first device (1).

5. Arrangement according to claim 4, wherein the first device (1) furthermore comprises a rectifier (11) which is installed between the coil (12) and the rechargeable accumulator (4).

6. Arrangement according to claim 1, wherein the first device (1) furthermore comprises a switching element (5) that is installed between the at least one lighting unit (3) and the at least one rechargeable accumulator (4).

7. Arrangement according to claim 6, wherein the switching element (5) is connected to at least one element from a group comprising a sensor (16, 20) and a clock (15).

8. Arrangement according to claim 1, wherein the at least one lighting unit (3) is a light emitting diode (LED).

9. Arrangement according to claim 1, wherein the at least one rechargeable accumulator (4) is a capacitor.

10. Device for lighting an object, comprising:

at least one lighting unit (3);

at least one rechargeable accumulator (4) connected to the at least one lighting unit (3) in order to provide this with power;

characterised in that the device is permanently bound to its surroundings.

11. Device according to claim 10, wherein the installation comprises two contact points (9) on one outer side, each contact point (9) of which is connected to a pole (7) of the at least one rechargeable accumulator (4).

12. Device according to claim 11, wherein the device furthermore comprises a rectifier (11), which is installed between one of the two contact points (9) and the pole (7) of the at least one rechargeable accumulator (4) connected thereto.

13. Device according to claim 10, wherein the device furthermore comprises a coil (12), which is connected to the at least one rechargeable accumulator (4), for generating a charge current if a fluctuating magnetic field is applied.

14. Device according to claim 13, wherein the device furthermore comprises a rectifier (11), which is installed between the coil (12) and the at least one rechargeable accumulator (4).

15. Device according to claim 10, wherein the device furthermore comprises a switching element (5), which is installed between the at least one lighting unit (3) and the at least one rechargeable accumulator (4).

16. Device according to claim 15, wherein the switching element (5) is connected to at least one element from a group comprising a sensor (16, 20) and a clock (15).

17. Device according claim 10, wherein the at least one lighting unit (3) is a light emitting diode (LED).

18. Method for lighting an object in locations without an electrical infrastructure, comprising:

positioning and firmly fixing at least one first device (1) in at least one location, the at least one first device (1) comprising at least one lighting unit (3) and at least one rechargeable accumulator (4), which is connected to the at least one lighting unit (3) in order to be able to provide this with power,

periodic charging of the rechargeable accumulator (4) of the at least one first device (1) with the aid of a movable second device (2), which comprises a charger (6).
