    摘要： A discharge lamp includes an emitter other than thorium, which is added to a cathode in a luminous tube. Early depletion of the emitter due to excessive vaporization of the emitter from the cathode is prevented, while achieving stable lighting even at the start-up of the lighting. A main body part (31) of the cathode (3) is made from a high-melting-point metal material that contains no thorium, and a front end part (32) thereof is made from a high-melting-point metal material that contains an emitter (other than thorium). A sintered compact (34), which contains an emitter (other than thorium) at a concentration higher than the emitter contained in the front end part (32), is buried in a sealed space (33) that is formed within the main body part (31) and/or the front end part (32). The sintered compact (34) abuts against the front end part (32).

    摘要： Disclosed herein a discharge lamp lighting device capable of suppressing an occurrence of a flicker and obtaining a longer life till flicker even when the discharge lamp lights up for a long time. The device comprises a short arc type discharge lamp; a lighting circuit for supplying power to the discharge lamp; and a controller for controlling the lighting circuit. The discharge lamp has: an arc tube; an anode and a cathode disposed in the arc tube with the anode and the cathode facing each other; and a xenon gas enclosed in the arc tube, and the cathode includes an electron emissive material and a carbon component. The controller includes a short time lighting circuit for carrying out a short time lighting operation that lights up the discharge lamp at least once in a short time during an idle period in which the discharge lamp does not constantly light up.
