Abstract
The present disclosure generally relates to field emission cathode structure for a field emission arrangement, specifically adapted for enhance reliability and prolong the lifetime of the field emission arrangement by arranging a getter element underneath a gas permeable portion of the field emission cathode structure. The present disclosure also relates to a field emission lighting arrangement comprising such a field emission cathode structure and to a field emission lighting system.

A field emission cathode structure for a field emission arrangement, comprising:
- a substrate having a first and a second side;
- a getter element arranged on top of the first side of the substrate and covering a portion of the first side of the substrate;
- an at least partly permeable structure arranged on top of at least a portion of the getter element;
- and
- an electron emission source arranged to cover a portion of the at least partly permeable structure,
- wherein the getter element is sandwiched between the substrate and the at least partly permeable structure.
