Light emitting arrangement and method for anti-fouling of a protected surface

A light emitting arrangement configured to realize anti-fouling of a protected surface of a marine structure when immersed in a fouling liquid containing biofouling organisms, the light emitting arrangement being shaped in sheet form and comprising:

• an optical medium and a light source embedded in the optical medium and configured to emit anti-fouling light, the optical medium allowing at least part of the anti-fouling light to distribute through the optical medium,
• the optical medium having a back surface to be arranged in or on the protected surface and an emission surface configured to emit the anti-fouling light in a direction away from the protected surface, and
• the light emitting arrangement further comprising at least one mirror configured to reflect anti-fouling light from the light source towards the emission surface of the optical medium,
• wherein the mirror is arranged near or at the back surface and is electrically conductive and electrically coupled to the light source for providing a first electrode arranged for transferring electrical power between a power source and the light source.
