Title:
ANTI-FOULING SYSTEM WITH UPCONVERSION FOR GENERATING UV RADIATION
Document Type and Number:
WIPO Patent Application WO/2018/108645
Kind Code:
A3
Abstract:
The invention provides an anti-fouling device (10) comprising a window (100), a radiation concentrator optical element (200) and an upconversion element (300), wherein: said window (100) comprises an anti-fouling surface (110) for transmission of at least part of anti-fouling radiation (11) to the external of the device (10), wherein the window (100) is further transmissive for at least part of one or more of visible and IR radiation (1) from external of the device (10); the radiation concentrator optical element (200) is configured for concentrating at least part of said one or more of visible and IR radiation (1); and the upconversion element (300) is configured within the device (10), and is configured for upconverting at least part of said one or more of visible and IR radiation (1) into said anti- fouling radiation (11), wherein said anti-fouling radiation (11) comprises UV radiation.
