Abstract:
The present invention relates to afield emission cathode, comprising an at least partly electrically conductive base structure, and a plurality of electrically conductive micrometer sized sections spatially distributed at the base structure, wherein at least a portion of the plurality of micrometer sized sections each are provided with a plurality of electrically conductive nanostructures. Advantages of the invention include lower power consumption as well as an increase in light output of e.g. a field emission lighting arrangement comprising the field emission cathode.
