Abstract
A method of anti-fouling of a surface while said surface is at least partially submersed in an liquid environment, comprising: providing an anti-fouling light; distributing at least part of the light through an optical medium comprising a silicone material and/or UV grade fused silica; emitting the anti-fouling light from the optical medium and from the surface.

A method of anti-fouling of a protected surface, comprising, while the protected surface is at least partially submersed in a liquid environment:
- providing an anti-fouling light,
- providing a direct-lit optical medium in close proximity to the protected surface, the optical medium having an emission surface, and
- emitting the anti-fouling light from the emission surface of the optical medium in a direction away from the protected surface.
A module for anti-fouling of a protected surface, comprising:
- a light source for generating the anti-fouling light, and
- a direct-lit optical medium having an emission surface for emitting anti-fouling light in a direction away from the protected surface when the module is arranged on the protected surface,
- wherein the module is configured to emit the anti-fouling light from the emission surface without letting the anti-fouling light travel a substantial distance therethrough substantially parallel to the emission surface.
