Abstract: A Far UV C excimer bulb assembly including an excimer bulb, and a curved filter external to and separated from the excimer bulb. The curved filter being hafnium based and including an arc. The excimer bulb emits radiation in a plurality of wavelengths substantially comprising Far UV C. The curved filter having a cut-off wavelength of 234 nm and adapted to block substantially all wavelengths of UV C radiation longer than 234 nm. The excimer bulb is positioned at least partially and centered within the arc so that the majority of the Far UV C wavelengths of radiation pass perpendicularly through the curved filter. The assembly may further include a mirror which may also be curved, and plated onto the exterior surface of the excimer bulb.

Abstract: A field emission cathode for use in flat panel displays comprises a layer of conductive material and a layer of amorphic diamond film, functioning as a low effective work-function material, deposited over the conductive material to form emission sites. The emission sites each contain at least two sub-regions having differing electron affinities. The cathode may be used to form a computer screen or a fluorescent light source.

Abstract: An electronic light radiation tube wherein a cathode and an anode disposed as spaced from each other by a small spacing are housed in an envelope enclosing therein a luminous gas, and a magnetic field is applied to the envelope so as to cause magnetic lines of force of the magnetic field to pass through the envelope, while the magnetic lines of force which have passed through the cathode are prevented from passing through the anode, whereby electrons emitted from the cathode are caused to collide at a high efficiency with the luminous gas throughout the entire interior space of the envelope to excite the gas, and highly uniform light radiation can be realized over the entire envelope.

Abstract: The lamp shown herein is a beam mode fluorescent lamp for general lighting applications. The lamp comprises a light transmitting envelope, having a phosphor coating on its inner surface, enclosing a single electrode including a thermionic cathode for emitting electrons and an integral anode for accelerating the electrons and forming an electron beam, and a fill material, such as mercury, which emits ultraviolet radiation upon excitation. The electrode configuration provides for use of a single power source and minimal number of power leads. In addition, a separate cathode heater filament is not required.

Abstract: An evacuated glass envelope contains a plurality of selectively energizable phosphor-coated elements (anodes) for presenting a symbol display. One or more thermionic cathodes are situated between the display elements and the display surface of the envelope to provide a direct electron beam to the phosphor-coated surfaces. The dull red glow of the thermionic cathodes is masked by the symbol display itself and, optionally, by a filter covering the display surface of the envelope. Variations in intensity at the end portions of the display elements are prevented by eliminating insulating members which would accumulate a charge tending to repel the electron beam. Optionally, the end portions of the display elements may be extended and curved to overlap one another and thus provide a symbol display formed by an unbroken luminous field.

Abstract: An excimer bulb assembly including an excimer bulb and a pass filter such that the excimer bulb assembly does not emit substantial UV radiation in wavelengths longer than 231 nm, 232 nm, 233 nm, 234 nm or 235 nm. The wavelengths are measured at an incident angle of zero (0) degrees to the filter plane. The pass filter is preferably constructed of a plurality of layers of hafnium oxide, and most preferably constructed of less than seventy five (75) layers of hafnium oxide. The excimer bulb, pass filter, and two electrical connectors may be adapted to form a cartridge which may be adapted to swivel along its main axis. The cartridge may further include a smart chip. The smart chip may retain and store information regarding the assembly and preferably retains hours of use of the excimer bulb.
