Abstract: A method and apparatus for increasing the emission amount of red such that it is made the same as the emission amount of green and blue, to enable the application state of the fluophors to be easily tested within a short time. Light from a discharge lamp of the short-arc type in which the arc tube is filled with cadmium and rare gas and which has emission lines between 200 nm and 230 nm is radiated onto fluophors of a test article such as the substrate for a display or the like. The fluorescence produced by these fluophors is received by a CCD sensor, and displayed in a display part, and thus the application state, such as faults of the fluophors or the like, is checked. The images picked up by the CCD camera can also be input to a control device and thus testing can be automated.

Abstract: While high heat is generated in the anode section in the gas discharge tube in accordance with the present invention during its use, the heat is transmitted to the stem by way of the anode support plate due to a configuration in which the anode support plate abuts against the stem, and is released outside from the stem, whereby the cooling efficiency of the anode section is improved. Since the anode section employs not a floating structure including stem pins interposed therein but a configuration in which it is seated on the stem by way of the anode support plate, the anode section is stabilized on the stem, whereby the resistance to vibration improves. Also, for assembling the anode section into a sealed envelope, it will be sufficient if the anode support plate is mounted on the stem, which contributes to improving the easiness in assembling the gas discharge tube.

Abstract: The amount of a metal halide to be enclosed in a generally ellipsoidal discharge space 24 within a discharge vessel 20a is set in the range 0.006-0.01 mg per unit volume (&mgr;l) of the discharge space 24. If the amount is less than 0.01 mg/&mgr;l, the deposit of metal halide 32 on the inner surface of the discharge space 20a in its lowest position midway between the narrow end portions thereof will not cause “shunting” of the arc between the electrodes 26A, 26B. As a result, the arc is effectively prevented from fizzling out after the metal halide lamp is switched on. To ensure that the metal halide lamp produces the intended luminous flux and color of light, the amount of the metal halide to be enclosed in the discharge space 24 should not be lower than 0.006 mg/&mgr;l.

Abstract: Visible light emission is obtained from a plasma containing elemental barium including neutral barium atoms and barium ion species. Neutral barium provides a strong green light emission in the center of the visible spectrum with a highly efficient conversion of electrical energy into visible light. By the selective excitation of barium ionic species, emission of visible light at longer and shorter wavelengths can be obtained simultaneously with the green emission from neutral barium, effectively providing light that is visually perceived as white. A discharge vessel contains the elemental barium and a buffer gas fill therein, and a discharge inducer is utilized to induce a desired discharge temperature and barium vapor pressure therein to produce from the barium vapor a visible light emission. The discharge can be induced utilizing a glow discharge between electrodes in the discharge vessel as well as by inductively or capacitively coupling RF energy into the plasma within the discharge vessel.

Abstract: Rare-earth halides are shown to be a replacement for scandium halides in mercury-free discharge arc lamps if modifications are made to the prior art lamp design and operating temperatures. The inventive chemical compositions of the discharge medium provide enhanced color rendition index values. In addition, it has been unexpectedly determined that during the operation of the discharge lamps, the rare earth iodides do not react significantly with the fused silica arc tube. Equally as significant, any free iodine, which is so formed, has minimal impact on the efficacy of the lamp compared to the conventional scandium iodide lamps. Therefore, the rare earth iodide-containing lamps provide longer lifetime with superior illumination characteristics than conventional discharge lamps.
