USED IN SHIPBUILDING COATING REFLECTING ULTRAVIOLET RADIATION, WITH WASHED OUT COLOUR Russian patent published in 2020 - IPC B63B59/04 

FIELD: transportation.

SUBSTANCE: invention relates to water vehicle (1) comprising housing (21) with coating layer (100), wherein water vehicle (1) further comprises anti-fouling system (200) comprising an optical medium and a light source, the configuration of which provides UV radiation, wherein optical medium (270) is transparent to light, wherein optical medium comprises radiation output surface and second surface of optical medium, and the configuration of at least part of the transparent optical medium material is such that it is located between said emission output surface and said second surface of the optical medium, wherein the configuration of the optical medium is such that it is adjacent to at least part of the coating layer, and the configuration of the second surface of optical medium (272) makes it closer to housing (21) than the radiation output surface, wherein anti-fouling system (200) configuration provides said UV radiation downstream of said emission output surface in direction from said housing (21), and wherein water vehicle (1) further comprises a structure comprising coloured segments and segments (131) which reflect UV radiation, wherein configuration of at least part of transparent material of optical medium is such that it is located between said structure and said radiation output surface.

EFFECT: invention allows achieving increased optical efficiency, while maintaining desirable external features and appearance (corporate colour) of the boat or body or surface.
