Abstract
The utility model relates to an arc tube for a medium- and high-power metal halide lamp. The arc tube comprises a quartz bulb shell and electrode assemblies sealed at both ends of the quartz bulb shell, wherein the bulb shell comprises three segments of straight quartz tubes connected with each other; the middle segment of the straight quartz tube serves as a discharge section; the straight quartz tubes connected with both ends of the discharge section serve as electrode package sections; the diameter of the discharge section is larger than that of the electrode package section; the electrode assemblies are arranged in the electrode package sections; and zirconia coatings are applied at the joint between the discharge section and two electrode package sections. The quartz bulb shell consisting of the three welded segments of the straight quartz tubes has convenient processing, and can lower the hydroxyl group of the quartz tubes so as to improve the lamp performance and prolong the lamp service life. The arc tube has less press-packaged area so as to reduce the thermal conduction loss and heat radiation loss of the bulb shell, and has more metal halide for discharging. The cavity of the arc tube is consistent with the arc in shape; and the arc tube has the advantages of uniform temperature distribution, less temperature difference, less color temperature drift, and good color consistence.
Description
Technical field
The utility model relates to the electric light source technology field, particularly a kind of middle high power Metal halogen lamp electric arc tube.
Background technology
At present, in the process of high power halogen electric arc tube, reduce the temperature difference and the thermal loss at each position of electric arc tube in manufacturing, the photochromic consistency of guaranteeing Metal halogen lamp is the key of making, and the set shape of change electric arc tube is the most direct approach.Traditional halogen electric arc tube is directly by the quartz ampoule compression moulding of straight tube shape, the press seal position area of this electric arc tube is very big, whole electric arc tube is also heavier, under the electric arc tube operating state, thermal conductance loss and the thermal radiation loss of cell-shell of electric arc tube by the press seal position is more serious, the temperature difference at each position of electric arc tube is bigger, bulb temperature is lower simultaneously, there is more metal halide can not enter discharge space, like this, the photochromic consistency of Metal halogen lamp is just good inadequately naturally, and light efficiency can not effectively be brought into play and improve.Quartz arc tube by blow molding is also arranged, its quartz ampoule cell-shell must become the quartz ampoule cell-shell bigger 3 to 4 times than original diameter through the less blow molding of quartz ampoule of a diameter, so not only the blowing time is long, the processing technology complexity, to the equipment requirements height, it is all very low to make qualification rate and operating efficiency, and, can cause the hydroxy radical content in the quartz ampoule cell-shell significantly to rise because long-time duration and degree of heating is fired, it is many unfavorable to bring for the performance of Metal halogen lamp and life-span.
The utility model content
The purpose of this utility model be to provide a kind of photoelectric parameter consistency better, be more suitable for processing and manufacturing, performance better in high power Metal halogen lamp electric arc tube.
The technical scheme that realizes the utility model purpose is: high power Metal halogen lamp electric arc tube in a kind of, electrode assemblie with quartz glass cell-shell and its two ends of inclosure, described cell-shell is formed by connecting by three sections straight pipe type quartz ampoules, the straight-run of pipe type quartz ampoule that wherein is arranged on the middle part is a discharge part, the straight pipe type quartz ampoule that is connected the discharge part two ends is an electrode package portion, described discharge part diameter is greater than electrode package portion, described electrode assemblie is arranged in the electrode package portion, and the electrode package portion junction at discharge part and two ends is provided with the zirconia coat.
The high power Metal halogen lamp adds the post forming welding with the employing that is connected between the electrode package portion at the discharge part of the cell-shell of electric arc tube and two ends in above-mentioned.
To be arranged in the electrode package portion with the electrode assemblie of electric arc tube be to add heat-sealablely by the straight tube shape quartz ampoule to electrode package portion to the high power Metal halogen lamp in above-mentioned, and electrode assemblie is fixed in the electrode package portion.
The high power Metal halogen lamp is provided with blast pipe with the discharge part housing of the cell-shell of electric arc tube in above-mentioned.
Above-mentioned in the high power Metal halogen lamp with electric arc tube be suitable for 575W, more than the 600W in the high power Metal halogen lamp.
The utlity model has following characteristics: the arc shape when the high power Metal halogen lamp is with electric arc tube and Metal halogen lamp work in of the present utility model coincide, with traditional directly by the halogen electric arc tube of straight tube shape quartz ampoule sealing-in with compare by the one-time formed halogen electric arc tube of quartz ampoule, following advantage is arranged:
1, because the quartz bulb shell of this metal halide lamp electric arc tube is to adopt three sections straight pipe type quartz ampoules to fire through duration and degree of heating to connect into the olive-type quartz ampoule, only need the part that connecting portion is heated during the duration and degree of heating heating, do not need all sites of quartz bulb shell is carried out long-time heating, reduce the burning time of duration and degree of heating in when blowing like this to quartz bulb shell, thereby saved the input of power-equipment, reduced the quartz ampoule hydroxyl, improved lamp behaviour and prolonged the lamp life-span.
2, the press seal area of electric arc tube reduces, and by the thermal conductance loss and the minimizing of cell-shell thermal radiation loss at press seal position, the cell-shell working temperature improves, and the metal halide that participates in discharge is more, and the light transmittance efficiency of lamp significantly improves more than 20%;
3, because arc tube chamber body profile and electric arc self shape are identical, thereby the Temperature Distribution of electric arc tube is more even, the temperature difference at each position of electric arc tube reduces, the colour temperature drift of lamp reduces, photochromic consistency is better, and this design more helps electric arc tube works under hyperbar and high temperature, and the startup of lamp and the time of restarting can shorten more than 50%, also reduced the blackout of lamp simultaneously, can be more than 30% than conventional lights life-saving.
