Abstract (en)
The present invention relates to a field emission lighting arrangement, comprising an evacuated envelope inside of which an anode structure comprising a phosphor layer and a field emission cathode are arranged, the anode structure being configured to receive electrons emitted by the field emission cathode and to generate light when a voltage is applied between the anode structure and the field emission cathode, wherein the evacuated envelope comprises a light exit portion and a light reflective portion being adapted to reflect light generated at the anode structure, and the field emission lighting arrangement further comprises a heat sink arranged outside of the evacuated envelope and thermally coupled to the light reflective portion. Advantages with the invention includes increase lifetime of the field emission lighting arrangement.
