## Abstract

The invention relates to a lamp with at least one lamp head and a base unit that each have a modular design to the effect that the lamp head can embody different geometric, optical and electronic configurations and the base unit can embody different geometric configurations. The lamp head has a retaining element that can be fastened via magnetic forces so as to be adjustable in terms of position to a holder of the base unit.

## Claims

### Claim 1

A lamp comprising at least one lamp head and a base unit, each having a modular structure to the effect that the lamp head can embody different geometrical, optical and electronic configurations and the base unit can embody different geometric configurations, wherein the lamp head has a retaining element that is fastened to a holder of the base unit via magnetic forces so as to be adjustable in terms of position to the holder, wherein the base unit has a modular arrangement of connecting pieces and branching elements, wherein the connecting pieces and the branching elements comprise hollow bodies into which electrical lines are routed, wherein central and external light-emitting diodes are provided as light sources, said central light-emitting diodes being arranged directly above a lens such that emitted light rays are bundled through the lens and outwards of the lamp in a directional fashion with characteristics of a spotlight, wherein said external light-emitting diodes are arranged in a ring such that emitted light rays from said external light-emitting diodes are directed outwards of the lamp at least partially in an indirect fashion after reflection from the lens and directly through a diffuser.

### Claim 2 (depends on 1)

The lamp according to claim 1, wherein the holder has a magnet with a contact surface having the shape of a spherical shell into which the retaining element of the lamp head is inserted, wherein said retaining element has a spherical shape and is made of a metallic material.

### Claim 3 (depends on 1)

The lamp according to claim 1, wherein the lamp head has a ring, wherein a cover is put on the top of said ring.

### Claim 4 (depends on 3)

The lamp according to claim 3, wherein the light sources are provided on the inside of the ring, wherein the light of said light sources is radiated through a diffusor at the bottom of the ring.

### Claim 5 (depends on 3)

The lamp according to claim 3, wherein the light sources are provided on the bottom of the cover.

### Claim 6 (depends on 5)

The lamp according to claim 5, wherein at least one central light-emitting diode that radiates light through the lens is provided at the bottom of the cover.

### Claim 7 (depends on 6)

The lamp according to claim 6, wherein said external light-emitting diodes are provided at the bottom of the cover that radiate light directly or through a diffusor after reflection at the lens.

### Claim 8 (depends on 7)

The lamp according to claim 7, wherein the diffusor is arranged on the bottom of the ring and wherein the lens is mounted in a central hole of the diffusor.

### Claim 9 (depends on 4)

The lamp according to claim 4, wherein the light sources are comprised of organic light-emitting diodes.

### Claim 10 (depends on 9)

The lamp according to claim 9, wherein the light sources and the accompanying electronic components for their control are arranged on a common circuit board.

### Claim 11 (depends on 10)

The lamp according to claim 10, wherein the electronic components form a dimmer capable of variable dimming.

### Claim 12 (depends on 3)

The lamp according to claim 3, wherein an electrical connector is provided on the ring.

### Claim 13 (depends on 1)

The lamp according to claim 1, wherein the connecting pieces each run along a straight line.

### Claim 14 (depends on 1)

The lamp according to claim 1, wherein the branching elements each have a quantity of branch segments.

### Claim 15 (depends on 14)

The lamp according to claim 14, wherein different branching elements are made up of different quantities and different spatial orientations of branch segments.

### Claim 16

A lamp comprising at least one lamp head and a base unit, each having a modular structure to the effect that the lamp head can embody different geometrical, optical and electronic configurations and the base unit can embody different geometric configurations, wherein the lamp head has a retaining element that is fastened to a holder of the base unit via magnetic forces so as to be adjustable in terms of position to the holder, wherein the base unit has a modular arrangement of connecting pieces and branching elements, wherein the connecting pieces and the branching elements comprise hollow bodies into which electrical lines are routed, wherein central and external light-emitting diodes are provided as light sources, said central light-emitting diodes being arranged directly above a lens such that emitted light rays are bundled through the lens and outwards of the lamp in a directional fashion with characteristics of a spotlight, wherein said external light-emitting diodes are arranged in a ring such that emitted light rays from said external light-emitting diodes are directed outwards of the lamp at least partially in an indirect fashion after reflection from the lens and directly through a diffuser, wherein the light-emitting diodes are organic light-emitting diodes.
