Abstract
The utility model relates to a metal halide tubular dysprosium lamp which has double layer tube shells. The utility model is characterized in that the double-layer tube shells are all made of quartz glass tubes, the length of the double-layer tube shells is the same to each other, and the end parts of the double-layer tube shells are formed into an integrative structure and are sealed on the molybdenum sheet of a same electrode contact; thereby, the utility model has the advantages of small volume, high lightness, good lighting color, long service life, convenient transportation and convenient installation. The utility model is widely suitable for the shoot of movie and video, and the utility model is widely suitable for the lighting of a cultural recreation place, a square and a tall public building.
Description
The utility model relates to discharge lamp, belongs to a kind of vapour discharge lamp with double-deck shell.
Along with the raising of people to the culture life requirement, the continuous appearance on the development of film, TV industry and tall and big office premises or square, require more and more higher to requisite lighting, require that light fixture has that volume is little, in light weight, brightness is high, photochromic good, characteristics that the life-span is long, the particularly shooting of film, TV, require the light fixture volume little, the similar daylight of light, high brightness and photochromic consistent stablizing.Improving constantly of science and technology development and lamp manufacturing process technical merit made it to occur to adapt to all gases, the vapour discharge lamp of different purposes.In the prior art, the lamp similar to the utility model is the tubular dysprosium lamp of a kind of metal halide, it has a bigger hard glass shell (generally all using 95 glass to make), be set with in the shell in the discharge of making by quartz glass tube and manage, inner chamber two end devices of pipe have two electrodes that are located along the same line and are separated by a segment distance in this, and electrode connection is drawn from glass outer pipe shell two ends; Should be pumped into vacuum in the interior pipe, and be filled with metal halide; Also be pumped into vacuum in the glass outer pipe shell, and housed joint be housed in two ends.There are many weak points in the tubular dysprosium lamp of this structure: at first, because of the hard glass heatproof is not too high, the high temperature when discharging for withstanding must be done the hard glass outer pipe shell greatlyyer, so the volume of class lamp is all bigger; Secondly, the glass shell of large volume brings the cold junction effect at pipe two ends in the discharge again, one section temperature promptly between pipe electrode is higher, and the temperature at two ends is lower, then metal halide just easily from the high-temperature region channelling to the lower temperature district, thereby cause its spectrum instability (variable color) of light of sending, especially when multi-lamp is formed colony's lamp, photochromic all inconsistent because of each lamp can be caused very big aberration, has a strong impact on the shooting quality of film and television; The 3rd, for vacuumizing, must be provided with the evacuated joint that leads to atmosphere at interior Guan Yiduan, gas leak phenomenon takes place easily; In addition, its mechanical strength of large volume lamp of this glass shell is also poor, and transportation is broken easily, and useful life is also low.Generally, the lamp of 400W power, its length needs 290 millimeters, and the outer pipe shell diameter is 122 millimeters, and average life span has only 1500 hours.
The utility model provides a kind of metal halide of high brightness tubular dysprosium lamp, make littler than existing tubular dysprosium lamp volume, brightness is high, photochromic good, the life-span long, transportation and installation are all more convenient.
For achieving the above object, the outer pipe shell of the utility model dysprosium lamp is made with quartz glass tube, is set with pipe in the known quartz glass discharge in the outer pipe shell inner chamber.The length of pipe in this is obtained consistently with the length of outer pipe shell in the design, both end sealing-ins are integral, and promptly the end of pipe in the end of quartz glass outer pipe shell and the quartz glass are packaged on the same electrode nipple molybdenum sheet with same position.Like this, pipe and outer pipe shell encapsulate lamp holder again and nut are installed in the sealing-in all-in-one-piece.
By last tubular dysprosium lamp structure as can be known: its outer pipe shell is made with quartz glass, the length of interior pipe is consistent with the length of outer pipe shell, and be packaged into one, then because the heatproof degree height of quartz glass, tube wall temperature is even, so can make the outer pipe shell of tubular dysprosium lamp less, so the utility model lamp is more much smaller than the volume of general dysprosium lamp; Also because the characteristic that had of the less and double-deck quartz glass shell of outer pipe shell size, electrode root (cold junction) temperature raising in the pipe has prevented the metal halide channelling preferably to cold junction in making, has also just increased the light efficiency of lamp, has improved photochromic stability; Outer pipe shell and interior pipe are packaged into one, make air-tightness greatly improve, and have deducted the Vacuum Package tube connector that general lamp must have, therefore the life-span of having improved the utility model dysprosium lamp; In addition, the also corresponding raising of volume-diminished, mechanical strength is convenient to transportation, is installed, and is difficult for Mechanical Crushing.
Description of drawings:
Fig. 1 is the structural representation of existing metal halide dysprosium lamp.
Fig. 2 is a structural representation of the present utility model.
Embodiment of the present utility model as shown in drawings.See by Fig. 2, be equipped with in pipe 3 inner chambers in the discharge made from quartz glass tube and be located along the same line and the electrode 2 of the segment distance of being separated by, this electrode is connected on the sealing-in molybdenum sheet 1, interior pipe 3 outsides are outer pipe shell 6 made from quartz glass tube, the length of outer pipe shell 6 is identical with the length of interior shell 3, and both equal sealing-ins are on same molybdenum sheet 1, and outer pipe shell 6 two ends are packaged with lamp holder 5, lamp holder 5 outsides are that nut 4 is installed, and molybdenum sheet 1 is connected with nut 4.
The specific embodiment of several different capacities of the present utility model is compared with existing metal halide dysprosium lamp, all seems superior at aspects such as physical dimension, luminous flux and average life spans, specifically sees Table one, table two.
