1. An anti-fouling unit configured to be arranged on a surface, wherein
the anti-fouling unit comprises at least one electric circuit including a light-emitting arrangement configured to emit anti-fouling light, and a plate-shaped carrier slab carrying the at least one electric circuit,
the carrier slab has an emission surface configured to allow light from the light-emitting arrangement of the at least one electric circuit to pass to outside of the anti-fouling unit and to thereby subject an exterior side of the emission surface and surroundings thereof to an anti-fouling action,
the carrier slab includes at least one active slab zone where the at least one electric circuit is located and at least one passive slab zone outside the active slab zone, which at least one passive slab zone is configured to allow a division of the anti-fouling unit in separate pieces in order to fit on a predetermined surface portion while keeping the functionality of the at least one electric circuit intact, and
the light-emitting arrangement of the at least one electric circuit is configured to subject the exterior side of the emission surface and surroundings thereof to an anti-fouling action both at a position of the at least one active slab zone and at a position of the at least one passive slab zone.
