Abstract

A luminaire arrangement for providing lighting in or near buildings. The luminaire arrangement may contain one or more of the following components: (i) at least one portable luminaire, which has a body and a lamp arrangement, (ii) at least one energy store, which is connected to the luminaire, is rechargeable, and is designed to supply electrical power to the lamp arrangement of the luminaire; and (iii) at least one charging device, which is designed to recharge the energy store. The energy store is attachable by means of an interface arrangement to the charging device in order to at least one of recharge the energy store and supply power to the lamp arrangement. The energy store is separable from the charging device in order to take the luminaire as necessary to any target location to be lit.

Claims

1. A luminaire arrangement for providing lighting in or near buildings, comprising:

at least one portable luminaire, which has a body and a lamp arrangement;

at least one energy store, which is connected to the luminaire, is rechargeable, and is designed to supply electrical power to the lamp arrangement of the luminaire; and

at least one charging device, which is designed to recharge the energy store,

the energy store being attachable by means of an interface arrangement to the charging device in order to at least one recharge the energy store and supply power to the lamp arrangement, and being separable from the charging device in order to take the luminaire as necessary to any target location to be lit.

2. The luminaire arrangement as claimed in claim 1, wherein the charging device and the energy store can be coupled by means of an inductive interface arrangement such that the energy store can be charged inductively.

3. The luminaire arrangement as claimed in claim 1, wherein the interface arrangement includes an electrical connection arrangement, the connection arrangement being held magnetically in a connection position, such that establishing at least one of the connecting arrangement and separation of the connection arrangement is facilitated.

4. The luminaire arrangement as claimed in claim 1, comprising a plurality of portable luminaires, which each has a control arrangement, each control arrangement including a wireless communications device, which communications devices can communicate with one another such that the luminaires can be switched jointly.

5. The luminaire arrangement as claimed in claim 1, the body of the luminaire defining a supporting plane and the interface arrangement having an electrical connection arrangement with a connection axis which is oriented transversely to the supporting plane.

6. The luminaire arrangement as claimed in claim 5, wherein the body of the luminaire has a recess, in which at least a portion of a charging device housing can be inserted, the shape of the recess and the shape of the charging device housing being coordinated with one another such that the charging device housing can be pivoted relative to the body of the luminaire parallel to the supporting plane by an angle which lies in a range of from 10°

to 90°

.

7. The luminaire arrangement as claimed in claim 5, the electrical connection arrangement having two concentric luminaire contacts on the body of the luminaire and two corresponding concentric charging contacts on a charging device housing.

8. A portable luminaire having a foot from which a pillar-like main body extends upwardly, a luminaire head being mounted at an upper end of the pillar-like main body, and a handle for carrying the luminaire being mounted on the main body in an area between the foot and the luminaire head, wherein the pillar-like main body has a longitudinal axis which is oriented at an angle (α

) in the range between 45° and

80°

with respect to a horizontal.

9. The luminaire as claimed in claim 8, wherein the foot defines a horizontal supporting plane and has an electrical interface arrangement that defines an interface axis which is oriented transversely to the horizontal supporting plane.

10. The luminaire as claimed in claim 8, wherein the foot of the luminaire has a recess, in which an electrical interface arrangement is located and in which at least a portion of a charging device housing can be inserted, the shape of the recess and the shape of the charging device housing being coordinated with one another such that the charging device housing can be pivoted relative to the foot of the luminaire parallel to the horizontal supporting plane by an angle which lies in a range of from 10°

to 90°

.

11. The luminaire as claimed in claim 10, wherein the recess is located at an underside of the foot and is arranged adjacent to, so that the charging device housing can be inserted into the recess in a vertical or in a horizontal direction.

12. A portable luminaire having a body which defines a body plane and in which a rechargeable electrical energy store is received, and having a lamp arrangement which has a light input portion and a luminous panel with a side edge, into which light from the light input portion is coupled, the luminous panel being oriented to the front at an angle of greater than 3°

and less than/equal to 90°

to the body plane, wherein a holding device in order to temporarily hold the body at a location to be lit, is located at a body rear side of the body.

13. The luminaire as claimed in claim 12, wherein an energy store is fixed to the body and is electrically connected to the lamp arrangement.

14. A charging device for a luminaire, wherein the charging device has a charging device housing, which has an underside, which can be set down on a base including a floor or a table, an upper side, and a side face connecting the underside and the upper side, a fixation surface for temporarily fixating the charging device housing against the base being formed on the upper side, and a charging interface for connection to a rechargeable energy store being arranged on at least one of the upper side and the side face.

15. The charging device as claimed in claim 14, a standard interface being formed on the charging device housing, via which standard interface an electrical charging DC voltage can be provided, the electrical standard interface in the charging device housing being electrically connected to charging contacts of the charging interface on the outer side of the charging device housing, the charging contacts being electrically connectable to luminaire contacts on a body of the luminaire.

16. The charging device as claimed in claim 15, wherein the charging contacts are arranged on the upper side of the charging device housing.

17. The charging device as claimed in claim 16, wherein the charging contacts include two charging contacts on the charging device housing, which two charging contacts are concentric with respect to an axis that is oriented transversely to the underside of the charging device housing.
