Illumination chain

1. Illumination chain, comprising:

a first illumination element; and

a multitude of further illumination elements, wherein each further illumination element is connected via a joint to the preceding illumination element;

wherein each illumination element comprises optics configured to emit light in an emission direction; and wherein each illumination element comprises an emission direction, and wherein all emission directions of all illumination elements are orientated equally;

wherein each illumination element comprises LED illuminants;

wherein the joint is realized by a connector belonging to the illumination element and extending beyond a round base shape of the illumination element, in connection with an engagement portion of the further illumination element connected to the illumination element, wherein the LED illuminant is embedded into the round base shape of the illumination element, wherein the engagement portion comprises a slit extending at an angle along a circumference of the round base shape of the illumination element, wherein a projection of the connector is introduced into the slit and is guided rotationally into the slit around the round base shape;

wherein, the joint allow a corresponding angular range between two illumination elements connected by the joint of at least at least 90 degrees or of at least 270 degrees.

2. Illumination chain according to claim 1 , wherein each joint comprises a device to carry a current.

3. Illumination chain according to claim 1 , wherein the joint is implemented by a joint; or wherein the joint is configured to limit three, four, or five degrees of freedom.

4. Illumination chain according to claim 1 , wherein the first illumination element comprises a current supply for the first illumination element and the further illumination elements.

5. Illumination chain according to claim 1 , wherein each illumination element comprises electronics and/or a current supply.

6. Illumination chain according to claim 1 , wherein the joint comprises a connection device so that the illumination elements connected by the joint are connectable and/or separable.

7. Illumination chain according to claim 1 , wherein the first illumination element comprises a connection device and/or a jointed connection device configured to connect the first illumination element to a further illumination element and/or to a further illumination element of a further illumination chain and/or a first illumination element of a further illumination chain.

8. Illumination chain according to claim 7 , wherein the connection device or the jointed connection device are configured so that a first illumination element of a further illumination chain is connectable to the first illumination element such that the multitude of the further illumination elements and the multitude of the further illumination elements of the further illumination chain are arranged in parallel.

9. System comprising a first and second illumination chain according to claim 1 , connected with each other so as to create a row of the illumination elements of the first and second illumination chains.

10. System comprising a first and a second illumination chain according to claim 1 , connected to each other so that the first and the second illumination chains form an illumination surface.
