低圧水銀蒸気放電灯に関する。[Detailed Description of the Invention] [Field of Application of the Invention] The present invention involves coating the inner surface of a glass tube with a phosphor or a phosphor containing other fine powder, and completely sealing the inside of the glass tube with mercury and inert gas. This invention relates to a low-pressure mercury vapor discharge lamp whose entire purpose is to emit light through discharge.

合点が生ずるという欠点があった。In fluorescent lamps, in order to prevent damage to the glass tube during the manufacturing process and maintain a high yield, it is necessary to keep the outer surface of the glass tube smooth. For this reason, in the past, 5 ozk was mixed into the burner gas during the firing process to decompose the binder after coating the phosphor, and a film of a substance containing Na 2 SOs as the main component was formed on the surface of the glass tube during firing. was being formed. However, when the solvent for the phosphor emulsion was changed from the conventional butyl acetate to water, the luminous flux maintenance rate decreased during long-term lighting, the deterioration rate was large after 100 hours of lighting, or the phosphor surface deteriorated after several tens of hours of lighting. There was a drawback in that it was colored ocher.
本発明は以上の不具合点全解決するもので１光束特性的

シやすくして、工程歩留りも高く維持できるような低圧
水銀蒸気放電灯全提供することにある。The present invention solves all of the above-mentioned problems and provides a complete low-pressure mercury vapor discharge lamp that can easily heat the surface of the glass tube and maintain a high process yield without causing any problems with the luminous flux characteristics. It is about providing.

特徴としている。In order to achieve the above object, the present invention is characterized in that a low-pressure mercury vapor discharge lamp is constructed by forming Naz S03 as a main component only on all or part of the outer surface of the glass tube.

特性が低下すると推定される実験的結果を得た。In other words, as a result of various studies, we found that the cause of problems with luminous flux is that a film containing Na25Cb (r as a main component) is formed not only on the outer surface of the glass tube but also on the np surface due to the contamination of 802 during the firing process. , Na28 formed on the inner surface
03 As a result of the film capturing moisture, it is estimated that after lighting, all Hg is attached to the phosphor surface, and the deterioration of the phosphor is accelerated by the reduction action of H20 due to H2O0 decomposition, resulting in a decrease in luminous flux characteristics. Experimental results were obtained.
したがって、ガラス管の内表面には５Ｃｈｋ流入させず
、外表面にのみ８０２を吹きつけて外表面にのみＮａ２
ＳＯｓＯｓ形成することでこの問題音解決するように
したものである。Therefore, 5Chk was not allowed to flow into the inner surface of the glass tube, but 802 was sprayed only onto the outer surface, and Na2 was only applied to the outer surface.
This problem was solved by forming SOsOs.

バーナガスにはＳＯ２に混入しない。FIG. 1 shows an embodiment of the method for manufacturing a fluorescent lamp according to the present invention, in which a phosphor and glass powder (3 wt% ) A glass tube 2 whose entire inner surface is coated with powder consisting of an aqueous emulsion (polyethylene oxide used as a total binder) containing k is heated. The temperature of the glass tube 2 at this time was 400 to 500C. Note that the burner gas in the firing furnace 1 does not mix with SO2.

いて１００ｈ劣化率５．５％。In the above-mentioned rung manufacturing process, the NazSOa film is provided only on the outer surface of the glass tube 2, so it is very efficient and the process yield is high, and since the Na2SO3 film is provided only on the outer surface, the luminous flux is The characteristics also have a 100h deterioration rate of 5.5% for FCL30W.
１０００ｈ光束維持羊９８％と良好な特性を有した。It had good characteristics with a luminous flux maintenance rate of 98% for 1000 hours.

良くなった。Figure 2 shows an example in which the purpose was to completely form NaxSOs only on a part of the external light surface of the glass tube.
By applying a gas flame 8 mixed with SO2 to the outer surface of the glass tube 6 using a burner 7 that matches the required length L of the glass tube 6, Na2SOs is applied to the area hit by the gas flame 8.
A film was formed, and the surface of the glass tube 60 in this area became smooth.

。As described above, in the present invention, Naz SOs #, which improves Dk, is completely formed only on the outer surface of the glass tube, and is not formed on the inner surface of the glass tube, so that the luminous flux of the lamp can be improved without reducing the process yield. All characteristics could be maintained in good condition.
