Abstract

The invention discloses a UV bulb structure, which comprises a quartz glass shell, a molybdenum sheet and mixed gas of Hg and Ar packed in the shell. The shell is in a cylindrical shape, and the bottom of the shell is provided with a protrusion, wherein the content of the Hg is less than 0.5 milligram. As the content of the packed Hg is small, the structure is not easy to burst under heat, and possibly caused pollution is effectively reduced at the same time. The invention also discloses a metal halide lamp, which comprises a UV bulb, two electrodes and an electric arc tube, wherein the molybdenum sheet of the UV bulb is connected with one electrode; the shell of the UV bulb is connected with the other electrode through a metal sheet or a metal wire; and the metal sheet or the metal wire is wound around the outside of the UV bulb shell. The metal halide lamp has the advantages of no radioactivity and small volume. The gas between the molybdenum sheet and the quartz glass shell discharges electricity so as to emit rays to irradiate the electric arc tube, which can effectively help to start the metal halide lamp.

Description

Metal halide lamp and UV bubble structure thereof
Technical field
The present invention relates to a kind of metal halide lamp, the particularly UV bubble structure in the metal halide lamp, and the metal halide lamp that adopts this UV bubble.
Background technology
The high intensity discharge metal halide lamp is used more and more widely, because gas phase halogen atom and halid existence make that at room temperature the starting resistor of MHL wants high than HPM and HPS; The hydrogen of introducing in the technological process also makes starting resistor raise; Electrode cools off too fast and adsorbs iodide, and work function value is risen, and everything all can cause Metal halogen lamp to start difficult problem, and product is in order to help startup in the past, and the adding radioactive substance causes very big pollution to environment.
UV (ultraviolet ray) bubble is set in ceramic gold-halogen lamp, and when Metal halogen lamp started, the ultraviolet ray that utilizes UV to steep to send or the electric arc tube of radiation of visible light Metal halogen lamp can play the effect of assistant starting.Need to fill Hg and Ar in the UV bubble, but the liquid Hg in the existing UV bubble adds too much, under higher temperature, explosion takes place in UV bubble easily.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of small size UV bubble structure that is difficult for explosion.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme: a kind of UV bubble structure, and comprise housing, the molybdenum sheet of quartz glass and be filled in Hg, Ar mist in the housing, described housing is cylindrical, and the bottom is provided with projection.
Preferably, the diameter≤3.5mm of described housing.
Preferably, the content of described Hg is less than 0.5mg.
More select ground, the content of described Hg is less than 0.3mg.
The invention has the beneficial effects as follows: because the volume of UV bubble is little, the Hg content of being filled is also very little, therefore is difficult for taking place explosion when being heated, and also effectively reduces the pollution that may cause simultaneously.
Another technical problem that the present invention will solve provides a kind of metal halide lamp, it comprises above-mentioned UV bubble, two electrodes and an electric arc tube, the molybdenum sheet of described UV bubble is connected with an electrode, the housing of UV bubble is connected with another root electrode by a sheet metal or wire, and described sheet metal or wire rings are around the outside of UV cell-shell body.
The advantage of this metal halide lamp is not have radioactivity, and volume is little, the gas discharge between molybdenum sheet and quartz glass, and the irradiation electric arc tube that emits beam can effectively help Metal halogen lamp to start.
Description of drawings
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
Fig. 1 is the UV bubble structure schematic diagram in a kind of metal halide lamp of the present invention.
Fig. 2 is the structural representation of a kind of metal halide lamp with UV bubble of the present invention.
Embodiment
At first as shown in Figure 1, a kind of UV of the present invention steeps and comprises housing 101, the molybdenum sheet 102 of quartz glass and be filled in Hg, Ar mist in the housing, and its middle shell 101 is cylindrical, diameter≤3.5mm, and the bottom of housing is provided with projection 103.During making, at first 102 spot welding are connected with molybdenum sheet with molybdenum rod, the molybdenum sheet 102 that connects are submerged in the quartz ampoule housing 101 the flame heat hermetic seal.The housing other end vacuumizes and charges into argon gas again after feeding argon gas and mercury, repeats to fill the process of taking out back sealed-off for several times.Take suitable process means to reduce liquid mercury as far as possible in the sealed-off process and be present in the UV bubble, mercury content can be less than 0.5mg, and more optimal is that mercury content can be less than 0.3mg.
A kind of metal halide lamp that adopts above-mentioned UV bubble as shown in Figure 2, in its outer glass bulb 7, comprise 3,4 and electric arc tubes 2 of UV 1, two electrode of bubble, the near-end of electric arc tube 2 is connected with electrode 3, the far-end of electric arc tube 2 is connected with electrode 4, and also is provided with the sheet 6 of cooling down on the electrode 4 and is used to guarantee vacuum degree in the lamp.The molybdenum sheet of UV bubble 1 is connected with an electrode 3, fixes a sheet metal or wire 5 on another root electrode 4, and sheet metal or wire 5 are looped around the outside that UV steeps 1 housing.
Electric arc tube 2 is made by highly purified transparent ceramic material, and a pair of thin tube part of heaving part and both sides by the centre on the structure is grouped into.The two ends of electric arc tube 2 seal with sealing plug, and are connected with a lead-in wire that is connected with electrode, scolder sealing-in between sealing plug and the earthenware.Part in the electric arc tube 2 between two electrodes is a region of discharge, generally be filled with in this zone and be used for luminous metal halide MXn (wherein halogen is generally all used iodide, uses bromide on a small quantity), start gas and buffer gas (mercury or fill the post of by inert gas and metal (as Zn) halide that can rapid evaporation).The inner surface of electric arc tube has also is coated with thin film, and the electric arc tube that has also is surrounded with protective cover and miscellaneous part outward.Glass bulb 7 and installing electrodes outside the suit outside electric arc tube are installed the UV bubble simultaneously between electrode, vacuumize sealing at last.
Metal halogen lamp of the present invention has the preferable performance parameter, and following table one, table two are results of experiment measuring:
