Patent attributes
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).
