    摘要: Disclosure is given for a method of forming and treating an arc tube (14), preferably for a metal halide lamp, such that end pockets (10) or other internal tube irregularities are eliminated. In one preferred embodiment the unwanted pockets are eliminated during the manufacturing process of the arc tubes. Therefor a press seal machine with 4 presses (2 pairs) was designed to provide pressing capability in two mutually perpendicular planes. With this machine a first press is made in the conventional manner with two opposing press feet (20, 22) being driven into the hot quartz of the arc tube body. While these feet are still in contact with the hot quartz, a second pair of press feet (24, 26) enter from the sides to flatten the sides of the press, and to dimple in the quartz with the press at arc chamber junction area (16) where end pockets are normally formed.

    摘要: In its most preferred embodiments, the present invention thus represents an improved Na-Sc-I lamp, wherein the improvement consists essentially of the addition of at least about 1 mg of particulate polycrystalline scandia to the arc tube. The positive benefits derived from this incorporation of PCS include improved lamp performance over long periods of time (e.g., 8000 hrs.) including improved lumen output, and improved maintenance and retention of CRI.

    摘要: A metal halide arc discharge lamp comprises an arc tube containing a chemical fill including mercury and metal halides and having first and second electrodes respectively sealed at opposite ends thereof. An outer envelope surrounds the arc tube and has first and second terminals for electrical connection thereto. An electrodeless source of ultraviolet radiation is provided within the outer envelope proximate the arc tube for producing radiation which illuminates the path between the electrodes of the arc tube to decrease the amount of time for generating a gaseous discharge therebetween. The ultraviolet light source includes an envelope of ultraviolet light transmitting material having opposing ends. Portions of the envelope of the ultraviolet light source are capacitively coupled across the electrodes of the arc tube such that the source produces ultraviolet radiation during lamp starting when the first and second terminals of the lamp are energized.

    摘要: A low wattage metal halide discharge lamp includes an evacuated outer envelope, a domed quartz sleeve therein and an arc tube within the domed quartz sleeve with the arc tube having a pair of electrodes press sealed therethrough with each of the electrodes having a coil thereon spaced from the press seal and from the end of the electrode to provide a figure of merit (FM) substantially equal to the product of the distance from the press seal to the coil and the distance from the press seal to the end of the electrode.
