Abstract:
The present invention relates to a field emission lighting arrangement, comprising a first field emission cathode, an anode structure comprising a phosphor layer, and an evacuated envelope inside of which the anode structure and the first field emission cathode are arranged, wherein the anode structure is configured to receive electrons emitted by the first field emission cathode when a voltage is applied between the anode structure and the first field emission cathode and to reflect light generated by the phosphor layer out from the evacuated chamber.Advantages of the invention include lower power consumption as well as an increase in light output of the field emission lighting arrangement.
