Abstract
The present invention generally relates to an extraction structure for a UV lighting element. The present invention also relates to a UV lamp comprising such an extraction structure onto a substrate. The extraction structure comprises a plurality of nanostructures for anti-reflecting purposes. The nanostructures are grown on the top surface of at least one of the first and second side of the substrate.
Claims24
An extraction structure for a UV light source, comprising:
- a substrate at least partly transparent to UV light, the substrate having a first and a second side, the first side of the substrate arranged to face the UV light source and to receive UV light emitted by the UV light source;
- and
- a plurality of nanostructures applied onto a top surface of at least one of the first and the second side of the substrate, the plurality of nanostructures configured to reduce an amount of UV light reflected by the substrate.
