Abstract: In the gas discharge tube of the present invention, for elongating the life of the discharge tube 1 itself while lowering the assembling temperature, a side tube 14 itself is formed from glass, and a metal is employed in a joint between a stem 4 and the side tube 14. Namely, a metal-made first peripheral portion 15 provided in the stem 4 and a metal-made second peripheral portion 16 provided in the side tube 14 are utilized in the joint. As a result, the discharge tube 1 itself can be made smaller.

Abstract: Light source (1) comprises a discharge vessel (2) filled with a gas and an electron beam source (4) located in a vacuum or in a region of low pressure. The electron beam source produces electrons (12) which enter the discharge vessel through a foil (8) having a diamond layer. An Independent claim is also included for a process for the production of the foil for the light source comprising depositing carbon atoms on a substrate (7) to form the diamond layer and back etching the substrate so that the remaining part of the substrate is molded into a frame for the foil. Preferably the diamond layer has a thickness of less than 100, especially less than 50 microns. The diamond layer has a metallic solder layer or an organic adhesive layer.

Abstract: A planar electron emitter, based on the existence of quasi-ballistic transport of electrons is disclosed. In its preferred embodiment the planar electron emitter structure consists of a body of finite gap pure semiconductor or insulator, the said body of macroscopic thickness (~1 mm) being terminated by two parallel surfaces and of a set of two electrodes deposited/grown on the said two free surfaces such that when a low external electrical field (~100 V/cm) is applied to this structure, consisting of two electrodes and the said semiconductor or insulating body sandwiched between them, a large fraction of electrons injected into the said semiconductor or insulator body from the negatively charged electrode (cathode) is quasi-ballistic in nature, that is this fraction of injected electrons is accelerated within the said semiconductor or insulator body without suffering any appreciable inelastic energy losses, thereby achieving sufficient energy and appropriate momentum at the positively charged electrode (anode) to be able to traverse through the said anode and to escape from the said structure into empty space (vacuum), said semiconductor or insulator body comprises a material or material system having a predetermined crystal orientation.

Abstract: A planar fluorescent and electroluminescent lamp having two pairs of electrodes. Planar electrodes on an outer surface of the lamp create a plasma arc by capacitive coupling. The planar electrodes also cause embedded phosphor to emit light on the electroluminescent phenomena. In one embodiment, a second chamber is on top of the first chamber and light passes from a primary chamber through the second chamber, and is emitted by the lamp.

Abstract: In an electron emitter device with a semiconductor substrate (20) bearing an n-conducting region (21) and a diamond layer (24), the novelty is that (a) the upper surface of the diamond layer (24) has an exposed region (29) below which the diamond layer is p-doped with a non-uniform doping profile increasing in the direction away from its upper surface; (b) the p-doped region (27) extends to a distance from the upper surface of the n-doped region (21) for forming an insulating region (28) which separates the two doped regions (27, 21); and (c) electrical contacts (23, 25) are provided on the lower surface of the substrate (20) and the upper surface of the diamond layer (24) so that, on voltage application, electron tunnelling occurs from the n-conductive region through the insulating region (28) into the p-conductive region (27) and electron emission occurs from the exposed region (29).

Abstract: An improved lighting system (10) which in the preferred embodiment includes a cathode (12) having an external surface (34) being coated with a cathode outside film (40) for emitting electrons therefrom. A first anode (14) extends internal to the cathode (12) for heating the cathode (12) to thereby emit electrons from the external surface (34). A second anode (16) is positionally located external to the enclosed cathode (12) for accelerating the electrons emitted from the cathode external surface (34). A bulb member (18) encompasses the cathode (12), the first anode (14), and the second anode (16) in a hermetic type seal. The bulb member (18) has a predetermined gas composition contained therein with the gas composition atoms being ionized by the cathode emitted electrons. The gas composition ionized atoms radiate in the ultraviolet bandwidth of the electromagnetic spectrum. The bulb member (18) is coated with a fluorescent material (20) for intercepting the ultraviolet energy responsive to the ionization of the gas composition atoms. The fluorescent material (20) radiates in the visible bandwidth of the electromagnetic spectrum to give a visible light output.
