Abstract: 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.

Abstract: An anode (1) in a field emission light source (15) is disclosed. The anode (1) comprises an electrically conductive layer (3) and a luminescent layer (5) that is luminescent when excited by electron bombardment (7) caused by a potential difference (9) between the electrically conductive layer (3) and a cathode (11). Key features are that the luminescent layer (5) is arranged between the electrically conductive layer (3) and the cathode (11) and that the electrically conductive layer (3) is a transparent electrically conducting layer (3). Further, a field emission light source (15) comprising the anode (1) is also disclosed.

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.
