313620000 | Having specified electrode spacing | 7 |
20100219751 | Direct-Current Discharge Lamp - A direct current discharge lamp with an anode ( | 09-02-2010 |
20120229023 | High-Pressure Discharge Lamp having a Single Socket - A high-pressure discharge lamp having a single socket, comprising: a discharge vessel ( | 09-13-2012 |
20130038207 | MERCURY-FREE HIGH INTENSITY GAS-DISCHARGE LAMP - The invention describes a mercury-free high-intensity gas-discharge lamp ( | 02-14-2013 |
20130099662 | METAL HALIDE LAMP WITH CERAMIC DISCHARGE TUBE - The present invention relates to a metal halide lamp with a ceramic discharge tube, which includes a ceramic discharge tube and two electrodes. The ceramic discharge tube includes a main discharge tube and two ceramic capillary tubes respectively located at two ends of the main discharge tube, the main discharge tube has a central protuberant part located in the middle thereof and two cylindrical parts respectively connected to two ends of the central protuberant part, the two cylindrical parts are respectively connected to the two ceramic capillary tubes. The shape of the ceramic discharge tube may, under the premise of maintaining high efficacy, effectively reduce the highest temperature in the center of the tube body, thereby greatly enhancing lamp reliability, and meanwhile with such structure, a fixed cold spot is also formed at a lower end of a discharge cavity formed at central protuberant part, so that a filler may always be fixedly deposited at the cold spot; in this way, the stability of the color temperature of the metal halide lamp with a ceramic discharge tube may be effectively improved. | 04-25-2013 |
20130257269 | METHOD OF MANUFACTURING AN ELECTRODE FOR A GAS DISCHARGE LAMP - The invention describes a method of manufacturing an electrode ( | 10-03-2013 |
20140015404 | SHORT ARC TYPE MERCURY LAMP - A short arc type mercury lamp structure has Hg and a rare gas which are enclosed inside a light-emitting tube. Kr is enclosed as the rare gas. It is possible to realize the initial intensity of radiation at the same level as in the case in which Ar is enclosed and prevent a sudden decrease in the intensity of radiation when the lamp is lighted for a long time. The longevity of the lamp is greatly increased than that of a lamp in which Ar is enclosed. The anode satisfies the formula: | 01-16-2014 |
20160190771 | Surge Arrester - A surge arrester includes a gas-tight discharge chamber that is formed by at least one insulating body and two electrodes. The electrodes extend into the discharge chamber and include an electrode spacing with respect to one another and a wall spacing with respect to the insulating body inner wall. The electrode spacing is equal to twice the wall spacing or is less than twice the wall spacing. | 06-30-2016 |
