    摘要： An electric lamp includes a tubular lamp envelope enclosing mercury vapor and a buffer gas, and a flag assembly located within the lamp envelope. The lamp envelope has a pair of dimples on an inside surface thereof. The flag assembly includes a support wire having opposite ends secured to the dimples and a starting flag attached to the support wire. The starting flag includes a mercury-absorbing material. The lamp envelope may be a closed loop electrodeless lamp envelope or a conventional electroded fluorescent lamp envelope.

    摘要： A negative glow fluorescent lamp includes a light-transmissive envelope enclosing a fill material which emits ultraviolet radiation upon excitation, a phosphor coating on an inner surface of the envelope, the phosphor coating emitting visible light upon absorption of ultraviolet radiation, a cathode located within the envelope for emitting electrons, first and second cathode leads extending through the envelope, an anode located in the envelope and spaced from the cathode for collecting electrons and first and second diodes coupled between opposite ends of the anode and the first and second cathode leads, respectively. The glow lamp can include one or more insulating discharge barriers which surround the cathode and block electron bombardment of the cathode during positive half cycles of the AC voltage. The discharge barriers are preferably as large in area as is practical and can be coated with an ultraviolet-reflecting material or with a phosphor layer. The glow lamp operates from an AC voltage and requires only two electrical connections. Lumen maintenance is improved because electron bombardment of the cathode is eliminated. A simple, low-cost ballast can be utilized.

    摘要： A glow discharge starter having an hermetically sealed envelope of vitreous material, a seal located at one end thereof and containing an ionizable medium. A pair of electrical conductors extend through the seal and terminate in a spaced relationship to form a pair of electrodes within the envelope. At least one of the electrodes has a bimetallic element secured thereto. The bimetallic element is deformable by heat into engagement with the other of the electrodes. Gettering means contained within the envelope reduces dark effect by improving dark starting and reduces aging time of the glow discharge starter. Preferably, the gettering means is a metal selected from the group consisting of bismuth and lead.

    摘要： An improved photoflash unit comprising a circuit board with lamp-firing circuitry thereon, a plurality (e.g., ten) of electrically activated photoflash lamps, and a reflector located between the lamps and circuitry. The lamp-firing circuitry includes at least one switch which is activated by radiant energy emitted from an adjacent photoflash lamp. The improvement comprises providing at least one longitudinal opening (slot) within a cavity portion of the reflector between the activating lamp and switch, and surrounding the opening with a transparent, non-conductive region to thereby assure consistent switch activation by substantially eliminating arcing between the reflector and circuitry.

    摘要： A photoflash unit comprising a linear array of flashlamps mounted on a printed circuit strip disposed within the longitudinal channel of an elongated housing member having an enclosing cover panel of light-transmitting material. The unit has connector terminals at opposite ends, and the linear array of flashlamps is divided into two groups disposed in opposite halves of the unit, each group of lamps being operated by the connector terminals at the remote end so as to reduce the red-eye photographic effect. The lamp-firing circuitry includes a pair of common circuit conductor runs respectively located on opposite halves of the printed circuit strip and on opposite sides of a common surface. An interconnecting jumper, or crossover, between the common circuit runs is provided through continuous conductive reflector surfaces on the housing channel which make contact with conductive deposits extending from the respective common circuit runs to the edge of the printed circuit strip.

    摘要： A photoflash unit comprising a plurality of high voltage type flashlamps mounted on a printed circuit board containing circuitry for sequentially igniting the flashlamps. A plurality of electrically conductive reflectors respectively associated with the flashlamps are disposed between the lamps and the circuit board, with each reflector having an aperture in alignment with a corresponding aperture in the circuit board. Connected in series with each but the last lamp of the array is a radiant-energy-activated disconnect switch comprising a strip of electrically conductive heat-shrinkable polymeric material which is attached at both ends to the circuit board so that the midportion of the strip bridges a respective one of the apertures therein. A sheet of electrically insulating material is interposed between the reflectors and circuit board to prevent shorting therebetween. A plurality of deformations, such as dimples, are formed in the insulating sheet for spacing the sheet from the disconnect switch strips.
