Description
The invention belongs to low-pressure mercury vapor discharge lamp, relate to narrow neck compact fluorescent lamp tube and uses thereof.
Low-pressure mercury vapor discharge lamp has the luminous efficiency height, and is photochromic good, and advantage of simple technology is used more and more widely in lighting field.Particularly the research report and the patent application of compact fluorescent lamp increase gradually in recent years." compact low-pressure mercury vapor discharge lamp " (notification number CN2123123U) as producer's development under the company of this group, a kind of compact low-pressure mercury vapor discharge lamp is disclosed, it comprises at least two coated inner wall fluorescent material and fluorescent tube parallel to each other, the fluorescent tube end interconnects, another end is provided with electrode, and with air tight manner sealing formation discharge cavity, if the end of electrode is that device is on lamp socket, it is characterized in that described connected component is to be made by the bend pipe structure of M shape, be provided with recessed ridge in the middle of it, both sides are provided with the grand shoulder of projection.Advantage is that grand shoulder position obtains suitable cold junction temperature, and light efficiency is up to 60.2lm/w.Shortcoming is that caliber is 12.5mm, and fluorescent tube is thicker, though power is bigger after making electronic energy-saving lamp, volume also increases, and uses to be subjected to certain restriction.And need lighter and handier, small-power, high light efficiency in the daily life at present, can give full play to the Subminiature electronic lamp of electricity-saving lamp advantage again.China illumination association's second phase nineteen ninety-five " the electric lighting bulletin " published has been reported the superfine caliber fluorescent lamp T of European OSRAM company
2(diameter is 6.5mm), Sweden AURA company has made 18W, 36W, the conventional lattice tubule of 58W footpath fluorescent lamp too, and length is respectively 0.59m, and 1.2m and 1.5m, light efficiency are respectively 61,80 and 79 lm/w, and color rendering index is 70.The height of photoelectricity index is conspicuous, and its shortcoming is that the length of straight pipe type fluorescent tube is more than 0.59m.Common Philip illumination company's thin and straight tube type fluorescent lamp (TLD lamp) equally also has high luminous efficiency on the market, is that the light efficiency of TLD/29 reaches 83 lm/w as model, color rendering index (Ra) 51, when identical light output than TL Lantern Festival electricity 10%.The invention first " low-pressure gaseous discharge lamp " of N.V. Philips' optical lamp manufacturing company (CN1062056A) disclosed also as above-mentioned similar two the electrode straight pipe type fluorescent lamps that contain, it is characterized in that each electrode contains the sintered mixture of different components: tungsten, barium monoxide, calcium oxide and strontium oxide strontia, the porosity of each electrode is less than 10%, and resistance is greater than 1 ohm.This invention has been done improvement to electrode, can control the life expectancy of lamp more accurately.Because this invention also is a kind of straight pipe type, volume is big, and it is their common drawback that use is inconvenient to.
Adopt the traditional type exhaust air technique at present, promptly utilize stern column to make aspirating hole, because the stern column internal diameter is 2.2mm only, it is again single-ended exhaust, when fluorescent tube elongated more, air drag is also big more, the speed of evacuation is also along with slowing down, one of them electrode is far away from steam vent during single-ended exhaust, another is then very approaching, therefore cause the decomposition condition imbalance of the electronics powder of two negative electrodes like this, emitting electrons ability and working life all produce difference, and it is bigger that this phenomenon contains the difference that the H fluorescent tube that connects bridge caused for the centre.This also is the key point that the compact fluorescent lamp tube quality is lower than same specification straight pipe type fluorescent lamp pipe.
According to interrelated data statistics, it is more than 1,000,000,000 that China uses incandescent lamp bulb at present, and about 80% be that the following small light of 40W is done life, work, study illumination.Many hotels, dining room, meeting room all design small-power babysbreath incandescent lamp, to eliminate dazzle, to beautify the environment, reach regulation illumination again.
Develop a kind of small-power, high light efficiency, photochromic good, volume is again little, can directly replace normally used incandescent lamp, and this is huge for the electricity consumption meaning that saves lighting.
Task of the present invention is to overcome above-mentioned deficiency, and a kind of high light efficiency, the narrow neck compact fluorescent lamp tube of light and handy, photochromic good, long working life again are provided, and its purposes is can make fluorescent lamp bulb directly to replace the following incandescent lamp of 40W.
The present invention is a kind of narrow neck compact fluorescent lamp tube and uses thereof, it comprises bent intermediate and straight-tube portion fluorescent tube parallel to each other, sealed at both ends and respectively put the discharge cavity that electrode constitutes, the tube inner wall coating fluorescent powder is characterized in that said tube diameter is 4.5mm-9mm.This fluorescent tube bent intermediate position is provided with steam vent, and fluorescent material is selected rare-earth trichromatic for use.Be provided with amalgam in the fluorescent tube, electrode is to be formed by weight 9: 1 sintering by tungsten and yittrium oxide.Its purposes is equipped standard lamp head, miniature electric ballast, constitutes miniature, ball-type, long-neck type, pyramid type or the tapered fluorescent lamp bulb of cylinder, steeps with direct replacement inky.
Advantage of the present invention is that tube diameter is the thinnest in the present compact fluorescent lamp, the volume of made velocitron also is the smallest and the most exquisite, the characteristics that have compact fluorescent lamp light efficiency height, photochromic good, long working life again, thereby made fluorescent lamp bulb and the 40W incandescent lamp bulb is similar can directly replace use.
Structure of the present invention, principle, effect and uses thereof be by following narration, and to consult Figure of description will be more clear and definite.
