Abstract:
In a flash lamp 1, a front end part 62 of a cathode 60 and a front end part 72 of an anode 70 are opposed to each other on a reference line RL, and with respect to a reference surface RS including the reference line RL, a front end part 82 of a trigger electrode 80 is located on one side, and a front end part 92 of a trigger electrode 90 is located on the other side. Further, a terminal end 82a of the front end part 82 of the trigger electrode 80 and a terminal end 92a of the front end part 92 of the trigger electrode 90 are separated from the reference line RL, and each front end part 82, 92 is formed so as to taper toward the reference line RL. Accordingly, an arc discharge occurs in a limited route R from a terminal end portion of the front end part 62 of the cathode 60 through a terminal end portion of the front end part 82 of the trigger electrode 80 and a terminal end portion of the front end part 92 of the trigger electrode 90 to a terminal end portion of the front end part 72 of the anode 70.
Abstract:
A discharge lamp lighting apparatus includes a capacitor, a charge circuit for charging the capacitor, a switching element, a gate driving circuit that controls ON and OFF states of the switching element, a simmer current supply circuit for passing simmer current through a discharge lamp, a starting circuit that impresses high voltage to a starting electrode, and an electric discharge sequence control circuit that generates the gate signal and the starting signal. When lighting the discharge lamp, a sequence of the gate signal corresponding to an alternating repetition of the ON and OFF states of the switching element is generated. Before outputting the starting signal, the switching element is ON as a stand-by state. Then the sequence starts when the starting signal is outputted.
Abstract:
A laser excitation lamp has a discharge tube and a hot cathode in the shape of a pin. The gas space is reduced in the region of the pin cathode. A method is also provided for production of the lamp, in which the gas space or the free cross section around the cathode is reduced by another processing step. The laser excitation lamp may be used as a pumping light source for lasing media.

Abstract:
First and second substrates are spaced apart and joined around a perimeter to define a gas chamber between the substrates. The first substrate is made of a material that transmits visible radiation. A layer of a phosphor material overlies an interior surface of one of the substrates and is capable of converting UV radiation to visible radiation. A layer of a reflective material overlies an interior surface of the other one of the substrates.

Abstract:
An apparatus for producing electromagnetic radiation includes a flow generator configured to generate a flow of liquid along an inside surface of an envelope, first and second electrodes configured to generate an electrical arc within the envelope to produce the electromagnetic radiation, and an exhaust chamber extending outwardly beyond one of the electrodes, configured to accommodate a portion of the flow of liquid. In another aspect, the flow generator is electrically insulated. In another aspect, the electrodes are configured to generate an electrical discharge pulse to produce an irradiance flash, and the apparatus includes a removal device configured to remove particulate contamination from the liquid, the particulate contamination being released during the flash and being different than that released by the electrodes during continuous operation.
Abstract:
In a light source, a heat sink is in contact with a side-on type discharge tube 110. The heat sink is in contact with a peripheral region 110ws around an exit window 101ww of the discharge tube 110. The heat sink consists of a spring member 101sp kept in direct contact with the peripheral region 101ws, and a radiating block 101bl which connects the spring member 101sp to a radiator box 101bx. Since materials made by sputtering or the like of electrodes in the discharge tube 110 mostly attach to the peripheral region 101ws of side wall 101w, it is feasible to decrease the amount of materials attaching to the exit window 101ww and, in turn, lengthen the lifetime of the discharge tube. Another light source may be constructed in structure in which the heat sink is in contact with a head-on type discharge tube or in structure in which light is outputted from a projecting portion.
Abstract:
A probe stabilized arc discharge lamp including a base portion, a window spaced from the base portion, a side wall interconnecting the base portion with the window. The side wall, the base portion, and the window define a chamber. A first electrode is disposed vertically in the chamber and extends outwardly through the base portion. A second electrode is also disposed vertically in the chamber and is spaced from the first electrode. The second electrode extends outwardly through the base portion. The first and second electrodes define an arc gap. There is also at least one trigger probe extending to or proximate to the arc gap for triggering an arc in the arc gap. Also, a reflector is disposed about the arc gap for directing radiation generated by the arc out the window. A sparker may also be provided.
