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: 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) 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.

Abstract: En la presente invencion se describe un cátodo de emision por campo, mejorado, y métodos para fabricar ese cátodo. En los métodos de la invencion, el cátodo de emision por campo se fabrica a partir de al menos un cuerpo que contiene una primera substancia. Los pasos del método incluyen una preparacion de irregularidades en una superficie emisora del cuerpo, adicionar a la superficie emisora del cuerpo, iones de una segunda substancia que tiene una funcion trabajo (energía mínima que es preciso comunicar a un electron para que pueda sobrepasar la barrera de potencial) baja, y modificar la superficie emisora induciendo la emision de campo al aplicar un campo eléctrico variable al cuerpo e incrementar la intensidad del campo, en pasos.
