Abstract
To ensure an energy-efficient transfer of light signals between two elements of a machine which are movable relative to one another, a device and a method for transferring light signals between such elements is provided. A first element has a plurality of light sources for delivering light signals and a second element has at least one photoreceiver for receiving the light signals. A unit causing the turning on or off is configured such as to effect a turning on or off of only one portion of the light sources.

A device for transferring light signals between two elements of a machine which are movable relative to one another, comprising:
- a first element having a plurality of light sources for delivering light signals;
- a second element having a photoreceiver for receiving the light signals;
- and
- a unit causing the delivery of the light signals, wherein the unit effects a turning on or off of only one portion of the light sources.
A method for transferring light signals between two elements of a machine, the elements moving relative to one another, comprising:
- delivering light signals by a first element having a plurality of light sources, wherein only one portion of the light sources delivers light signals simultaneously;
- and
- receiving the light signals by a second element having a photoreceiver.
