Abstract: 87-1-123 PATENT PULSED LIGHT SOURCE A pulsed light source includes a sealed, ultraviolet-transmissive lamp tube defining a discharge region containing a rare gas or a mixture of rare gases, anode and cathode electrodes sealed into the lamp tube at opposite ends, leads for connecting the electrodes to a pulsed source of electrical energy and a phosphor material, located on a surface external to the discharge region. The lamp tube contains mercury in sufficient quantity to cover the cathode electrode when the lamp tube is oriented with the cathode electrode at the bottom. The cathode electrode is protected by the mercury from sputtering that results from ion bombardment. The mercury emits pulsed ultraviolet radiation which stimulates emission of visible light by the phosphor material. Lamp tube pressure is below 200 torr. The light source is operable over a range of pulse widths and duty cycles. The color of light emission is determined by the phosphor. The phosphor can be located on the outer surface of the lamp tube or on a separate glass sleeve.

Abstract: 2082385 9120173 PCTABS00009 A ballast for starting and operating a high intensity discharge (HID) lamp in a dc mode includes an oscillator coupled to first and second direct current input terminals. The oscillator includes a high frequency generator driving a pair of semiconductor switches. A first transformer having primary and secondary windings is coupled to the semiconductor switches. A rectifier and voltage multiplier circuit converts the voltage across the secondary winding of the first transformer to a dc voltage. A first energy storage circuit coupled to the rectifier and voltage multiplier circuit stores energy for generating a negative-going, high-voltage spike sufficient for initiating a glow condition in the lamp. A second energy storage circuit, which stores energy for application to the HID lamp during starting insures proper glow-to-arc transition. The starting and operating circuit further includes a control circuit for regulating lamp power in response to control signals received from voltage and current monitoring circuits.

Abstract: A low wattage single-ended metal halide arc discharge lamp has an isothermal arc chamber with an outer diameter (t) substantially equal to the product of a first constant and the lamp wattage plus a second constant; a fill gas and a pair of electrical conductors sealed into and passing through one end of the arc chamber to provide a pair of electrodes therein having a spacing therebetween of a distance to provide a substantially uniform current for lamps in the range of about 35 to 150 watts.

Abstract: The present invention is directed to a new type of colored light source especially well suited for use as a signal and/or navigational aid. The source is also adaptable to many other applications requiring momentary flashes of a particular color of light. The mercury-free, pulsed metal halide light source of the present invention comprises in combination: (a) a light transmissive glass vacuum outer jacket; (b) a light transmissive glass arc tube disposed within said outer jacket; (c) emissive material comprising at least one metal halide salt and an inert gas; and (d) an anode and a cathode, disposed within said arc tube, forming a gap therebetween; said cathode being completely covered by said metal halide salt.
