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