6. The kit or system of claim 5 , wherein each of the attachable dividers comprises contacts for piercing the supporting line to make electrical contact with the data link to perform said communication with the at least one neighbouring lighting node, or for piercing the supporting line to make electrical contact with the power line in order to perform said drawing or supply of power.

7. The kit or system of claim 1 , wherein each of the attachable dividers comprises a blade for severing at least the data link in order to create said intersection.

8. The kit or system of claim 1 , wherein:

each of the attachable dividers is configured to enable said detection based on a wireless signal transmitted or reflected between the attachable divider and at least one of the respective pair of neighbouring lighting nodes, or between the attachable divider and a component embedded in the line.

9. The kit or system of claim 1 , wherein at least one of the attachable dividers is further arranged to mechanically support or be supported by a luminaire element.

10. The kit or system of claim 9 , wherein:

each of the attachable dividers is configured to enable said detection by communicating with at least one of the respective pair of neighbouring lighting nodes or with a component embedded in the line;

for said at least one attachable divider, said communication between the attachable divider and the at least one neighbouring lighting node further enables identification of a property of the luminaire element; and

the controller is configured to control the lighting effect in one of the segments bounded by said at least one attachable divider in dependence on the identified property of the luminaire element.

11. A system comprising:

a linear array of lighting nodes connected at different respective positions along a flexible, rigid or malleable continuous supporting line, each of the lighting nodes comprising one or more lighting elements for emitting illumination;

one or more attachable dividers attached onto said line without severing the line, or at least without completely severing the line, each between a respective pair of the lighting nodes, by means of a mechanical attachment; and

a controller arranged to control the illumination emitted by each of the lighting nodes;

wherein each of the attachable dividers is configured so as, when attached onto the line, to enable detection of a position at which the divider is attached along the line relative to the lighting nodes, and configured to provide information related to said position to the controller, and thereby divide the lighting nodes into different segments along the line; and

wherein the controller is configured to apply a different lighting effect to the illumination emitted by the lighting nodes in each of some or all of the different segments;

a sequential data link connecting a linear sequence of data nodes, each but a first of the data nodes in the sequence being arranged to receive data from a preceding one of the data nodes in the sequence and pass the data to a next one of said data nodes in the sequence;

wherein said lighting nodes each comprise a respective one of the data nodes; and

wherein each of the attachable dividers is configured so as, when attached to the supporting line by said mechanical attachment, to intersect the data link to become another of said data nodes, and thereby communicate with at least one of the respective pair of neighbouring lighting nodes in order to enable said detection.

12. A method performed in relation to a linear array of lighting nodes connected at different respective positions along a flexible, rigid or malleable continuous supporting line, each of the lighting nodes comprising one or more lighting elements for emitting illumination; the method comprising:

attaching one or more attachable dividers onto said line without severing the line, or at least without completely severing the line, each between a respective neighbouring pair of the lighting nodes, by means of a mechanical attachment;

employing a controller for controlling the illumination emitted by each of the lighting nodes;

using each of the attachable dividers so as, when attached to the line, to detect a position at which each of the attachable dividers is connected along the line relative to the lighting nodes, and thereby the lighting nodes into different segments along the line;
