Light system for demarcating a field in a swimming pool, for example a water polo field

Abstract

A light demarcation system applicable to a predefined area of any water surface, such are being delimited by a bottom portion and by a pair of longitudinal walls and a pair of transverse walls of a length suitable for defining a water polo field, wherein the pair of transverse walls have a length smaller than the pair of longitudinal walls. The light demarcation system comprises one or more light profiles, each made up of a plurality of sequentially arranged light elements, in predefined positions inside and/or outside of the water polo field, and an electronic control system operatively connected by wireless or wired connectors to the light profiles for management of the operation of the light profiles.
