Abstract: A method of producing a field emission cathode for a light source, and including at least one field emitting body having a field emitting surface, wherein the method includes modifying said emitting surface so as to provide at least one electric field emitting irregularity in each said surface. The method is distinguished by at least one beam of laser light being brought to shape the body and to simultaneously contact the field emitting surface and thereby provide a modifying treatment to the surface of the body. The invention also concerns a field emission cathode so produced and a light source including such a field emission cathode.

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.

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: An arrangement for emitting light includes a hermetically sealed casing with a window, a layer of a fluorescent substance arranged within the casing covering at least a major part of the window, an electron emitting cathode arranged within the casing, and an anode. The casing is filled with a gas suitable for electron avalanche amplification. In operation, the cathode and anode are held at an electric potential such that said emitted electrons are accelerated and avalanche amplified in the gas. The layer of the fluorescent substance is arranged to emit light through the window in response to avalanche amplified electron bombardment and/or ultraviolet light emitted from the gas.
