Abstract

Applying a Ti02 nano coating comprising sterilizing properties when illuminated by daylight. Since hospitals etc. are often equipped with daylight filtering windows and/or shading etc., the invention provides for lighting devices with "full-spectrum daylight" (FSD) LED lighting within sterile rooms of hospitals etc., to remedy the lack of natural FSD. The nano-oxide coating has a layer thickness of <50 micron whereas the grain size of the nano-oxide particles is 50 - 75 nm. By adding silver (Ag+) ions, Ti(OH)4 and/or a phosphate mineral from the group Apatite to the nano-oxide coating, the efficiency of the Ti02 nano-coating irradiated by FSD is substantially improved for the sterilization of air. Additional to the full-spectrum daylight, the lighting devices are configured to emit ultra-violet radiation into the space, in particular UV-A and/or UV-B radiation, thereby obtaining a better "match".
