摘要： 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.

摘要： The present invention relates to an arrangement for emitting light comprising: a hermetically sealed casing (4) including a transparent or translucent window (10); a layer (3) of a fluorescent substance arranged within said casing covering at least a major part of said window; an electron emitting cathode (1) arranged within said casing for emission of electrons; and an anode (2). Said casing is filled with a gas suitable for electron avalanche amplification. Said cathode and anode are, during use, held at electric potentials such that said emitted electrons are accelerated and avalanche amplified in said gas; and said layer is arranged to emit light through said window in response to being bombarded by avalanche amplified electrons and/or in response to being exposed to ultraviolet light as being emitted in the gas due to interactions between the avalanche amplified electrons and the gas.

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

摘要： An improved field emission cathode and methods for fabricating such a cathode are disclosed. In the methods of the invention, the field emission cathode is made from at least one body containing a first substance. The method steps include a preparation of irregularities 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.

摘要： An electron/photon source based on field emission, cathodoluminescence and photo-enhanced field emission, comprising an evacuated chamber inside a housing, further comprising an anode and a cathode arranged inside said evacuated chamber. Furthermore, the cathode is arranged to emit electrons when a voltage is applied between the anode and cathode, said anode being arranged to emit light at a first wavelength range when receiving electrons emitted from said cathode, and a wavelength range converting material arranged to receive said emitted light of said first wavelength range and emit light at a second wavelength range. In a novel way, the present invention makes it possible to, in two steps, convert the electrons emitted from the cathode to visible light. The invention has shown to be advantageous, and makes it possible to select new emission materials, manufactured at a fraction of the cost associated with the earlier used materials where the electron to visible light conversion was done in one step.
