    Abstract: A field emission cathode has particular use in a light source. The light source includes an evacuated container having walls, at least a portion of which consists of an outer glass layer which on at least a major part thereof is coated on the inside with a layer of phosphor forming a luminescent layer and a conductive layer forming an anode. The layer of phosphor is excited to luminescence by electron bombardment from a field emission cathode located in the interior of the container. A modulator electrode is arranged between the cathode and the anode for creating an electrical field necessary for the emission of electrons. The field emission cathode, includes a base body, and field emitting bodies extending from the base body. The base body includes a longitudinally extending core having a central axis. The field emitting bodies are elongate and are distributed along at least a part of the length of the core, extend radially outwards from the core, and have free ends provided with field emitting surfaces.

    Abstract: A field emission cathode and methods for fabricating such a cathode from at least one body containing a first substance. The steps include a preparation of at least one irregularity in an emitting surface of the body, adding to the emitting surface of the body ions of a second substance with a low work function, and modifying the emitting surface by inducing field emission in applying a variable electric field to the body and increasing the field strength in steps.

    Abstract: A field emission cathode (40) includes field emitting bodies (42) in the form of fibers, and a base body having a longitudinally extending core (41) formed by at least two wires (43) between which the fibers are secured. The fibers are distributed along at least a part of the length of the core (41) and extend radially outwards from the core. A light source (10) includes an evacuated container having walls at least a portion of which consists of an outer glass layer (23) on which at least a major part thereof is coated on the inside with a layer of phosphor (24) forming a luminescent layer, and a conductive layer forming an anode (25). The layer of phosphor (24) is excited to luminescence by electron bombardment from a field emission cathode (40) located in the interior of the container, and a modulator electrode or grid (30) is arranged between the cathode (40) and the anode (25) for creating an electric field for the emission of electrons. The field emission cathode (40) includes field emitting bodies (42) in the form of fibers, and a base body having a longitudinally extending core (41) formed by at least two wires (43) between which the fibers are secured.
