    Abstract: A light emitting arrangement (100) for anti-fouling of a surface (30), comprises an optical medium (10) and at least one light source (20) for emitting anti-fouling light. A first zone (1) of the arrangement (100), which is closest to the light source (20), is arranged and configured to predominantly make the anti-fouling light reflect in a specular manner towards an emission surface (12) of the optical medium (10), through the optical medium (10), a second zone (2) of the arrangement (100) is arranged and configured to predominantly realize propagation of the anti-fouling light through the optical medium (10) by total internal reflection, and a third zone (3) of the arrangement (100), which is furthest away from the light source (20), is arranged and configured to predominantly make the anti-fouling light scatter out of the optical medium (10), through the emission surface (12) of the optical medium (10).

    Abstract: A cooling apparatus for cooling a fluid by means of surface water, the cooling apparatus comprising more than one tubes for containing and transporting the fluid in its interior, the exterior of the tube being in operation at least partially submerged in the surface water so as to cool the tube to thereby also cool the fluid and hence different tube portions contain fluid at different temperatures. The cooling apparatus further comprises at least one light source for producing light that hinders fouling on the submerged exterior, wherein the at least one light source is arranged so that the intensity of the anti-fouling light, cast over the exterior of the tube portions whose exterior temperature or the temperature of the fluid they contain is below 80° C., is higher than the intensity of the anti-fouling light cast over the other tube portions. By this structure anti-fouling of the cooling apparatus can be assured in an effective manner.
