Abstract (en)
An anti-fouling light output system is for mounting over a surface to be protected. A lighting panel (20) has a first surface (51 )and an opposite second surface (52), wherein a waveguide is formed between the first and second surfaces. A light source (40) delivers light into the waveguide, and it is, or is converted into, anti-fouling light. The first surface of the panel is for application to the surface to be protected and the second surface is for facing outwardly from the surface to be protected. This second surface comprises a ribbed area (80, 90, 92) having ribs (82) for reducing drag, which ribs are transparent to the anti-fouling light. This arrangement thus combines two measures for drag reduction; a ribbed surface and delivery of anti-biofouling light through those ribs to prevent the formation of biofouling at the ribs.
