发明名称 Electrical power control of a field emission lighting system
摘要 The present invention relates to a field emission lighting arrangement, comprising an anode structure at least partly covered by a phosphor layer, an evacuated envelope inside of which an anode structure is arranged, and a field emission cathode, wherein the field emission lighting arrangement is configured to receive a drive signal for powering the field emission lighting arrangement and to sequentially activate selected portions of the phosphor layer for emitting light. The same control regime may be applied to an arrangement comprising a plurality of field emission cathodes and a single field emission anode. Advantages with the invention includes increase lifetime of the field emission lighting arrangement.
