- Patent Document 2 JP 2004-87397 A
- the present invention provides a method for producing a double spiral glass tube, which maintains the cooling effect of the coldest spot by the convex portion at a conventional level, and is less likely to break the convex portion than in the past.
- An object of the present invention is to provide an arc tube for a fluorescent lamp and a fluorescent lamp.
- the method for producing a double spiral glass tube according to the present invention includes a deformation step of softening a straight tubular glass tube and folding it back at a substantially central portion to deform the glass tube into a double spiral shape, A processing step of thickly processing the glass tube deformed in a spiral shape so that the thickness of the projected portion formation portion at the substantially central portion is thicker than the thickness of the non-convex portion formation planned portion at the substantially central portion. And by bulging the projected portion where the thick wall is processed Forming a convex portion at a projected portion formation scheduled portion.
- the processing step includes a blowing step of blowing gas from a glass tube end portion of a double spiral glass tube in a soft state, and the substantially central portion is formed by blowing the gas in the blowing step.
- a bulge restraining jig is provided at a predetermined position where the projected portion formation planned portion will come into contact with the bulge when the bulged portion is expanded. It is good also as including the bulging suppression jig

- the bulge suppressing jig may be attached to the shaping jig! /.
- the method for manufacturing a double spiral glass tube according to the present invention includes a deformation step of softening a straight tubular glass tube and folding it back at a substantially central portion to deform the glass tube into a double spiral shape, The farthest portion where the linear distance from both ends of the glass tube at the substantially central portion of the deformed glass tube is the farthest is thicker than the non-farthest portion at the substantially central portion. And a processing step for processing a thick wall.
- the thickness of the glass tube at the convex portion is at least 0.1 mm.
- the arc tube for a fluorescent lamp according to the present invention has a wall thickness of the farthest portion in the substantially central portion of the double spiral glass tube having the farthest linear distance of the force at both ends of the glass tube. It is thicker than the thickness of the glass tube at the non-farthest part in the substantially central portion.
- the fluorescent lamp according to the present invention comprises the fluorescent lamp arc tube described above.
- the inventor found that the problem that the convex portion is easily damaged was formed in the glass tube. It was elucidated that it was caused by a decrease in mechanical strength due to thinning of the convex part. That is, since the convex part is formed by the bulging of the part where the convex part is to be formed, the convex part is inevitably thinner than the part other than the convex part and becomes a relatively easily damaged part.
- the thickness of the glass tube of the projected portion can be increased as compared with the conventional manufacturing method without performing thick processing. Therefore, the mechanical strength of the convex portion can be improved, and as a result, the convex portion can be made harder to break than in the past.
- the glass material that should be bulged is a thick pool Part. Therefore, the thickness of the projected portion formation planned portion can be made larger than the thickness of the non-projected portion formed planned portion.
- the abutting portion is flat as described in claim 3, the area of the glass tube that abuts against the bulging suppression jig is smaller than when the abutting portion is not flat. Therefore, it is possible to selectively increase the thickness of only the projected portion formation planned portion.
- the shaping processing of the spiral portion shape and the thick wall processing of the projected portion formation scheduled portion can be performed in the same process. Therefore, it is possible to avoid an increase in work man-hours due to the provision of the bulge suppressing jig.
- the inventor further provides the bulb-shaped fluorescent lamp manufacturing process to which the double spiral glass tube having no convex portion is applied, and the farthest of the most central portion of the double spiral glass tube. I noticed that the site was easily damaged. This is because, when assembled as a lamp, the farthest part is the tip of the lamp, so it is most likely to be damaged when subjected to vibration or impact during transportation or dropping.
- the farthest part is processed with a thick wall, the mechanical strength of the farthest part can be improved, and as a result, the farthest part can be damaged as compared with the prior art. It is possible to do this.
- the inventor examined the arc tube structure for suppressing breakage of the convex portion. As a result The inventors have found that the thickness of the convex portion may be regulated to a value of at least 0.10 mm. As a result, the occurrence rate of damage in the manufacturing process of the convex portion can be suppressed to a level of 0.01% or less which is actually no problem.
- the breakage rate of 0.01% is a level that has hitherto been achieved in arc tubes other than the double spiral arc tube, such as a U-shaped arc tube. With the configuration described in claim 7, it is possible to reduce the rate of breakage to the level that has been achieved in the past.

- the thickness t4 of the apex portion is reduced to 0.05 mm.
- the thickness of the glass tube of the convex portion 14 can be increased as compared with the conventional manufacturing method. Therefore, the mechanical strength of the convex portion 14 can be improved, and as a result, the convex portion can be broken more than before.
- the inventor also examined the rate of occurrence of damage to the convex portion 14. As a result, it has been found that if the thickness t4 of the apex portion of the convex portion 14 is set to a value of 0.10 mm or more, the failure occurrence rate can be suppressed to a practically satisfactory level of 0.01% or less. In contrast, in the conventional manufacturing method, the thickness of the peak of the convex portion is about 0.05 mm, so the damage occurrence rate is about 3%, which is a big problem.
- the breakage rate of 0.01% is a level at which conventional power is also achieved in arc tubes other than the double spiral arc tube, such as a U-shaped arc tube.
- the failure occurrence rate can be suppressed to a level that has been achieved with a U-shaped arc tube. More preferably, it should be specified to a value of 0.20 mm or more. By doing so, the damage occurrence rate can be suppressed to a negligible level of 10 ppm or less.

- the present embodiment relates to a fluorescent lamp using an arc tube composed of a double spiral glass tube 2 in which a substantially central portion 13 is expanded and a convex portion 14 is formed thereon.
- the surface with which the projected portion formation scheduled portion 32 of the bulge suppressing jig 31 abuts is assumed to be flat (FIG. 8 (a)).
- the present invention is not limited to this as long as it has an effect of suppressing the bulge of the projected portion formation planned portion 32 more than the bulge of the non-projected portion formed planned portion in the substantially central portion 13.
- it may have a concave shape as shown in FIG.
- the projected portion forming portion 32 is on the spiral axis C of the substantially central portion 13, the surface on which the projected portion forming planned portion 32 of the bulge suppressing jig 31 abuts on the spiral axis C It is deployed to be vertical. However, if the projected part formation site 32 is in any other position,

- the bulging suppression jig 31 is arranged to face the position.
- the projected portion formation planned site 32 is set as the non-projected portion formation planned portion at the substantially central portion 13.

Furthermore, the inventor has also found that both ends of the glass tube in the substantially central portion of the double spiral glass tube are used in the manufacturing process of a bulb-type fluorescent lamp to which a conventional double spiral glass tube having no projection is applied. I noticed the problem that the farthest part where the linear distance of the force is the farthest is easy to break. As shown in Fig. 10, when assembled as a lamp, the outer tube glass bulb 17 is not provided, so the farthest part 34 is the tip of the lamp. This is the force most likely to break when an impact is applied.
- the farthest portion 34 is thickly processed so that the thickness of the glass tube is thicker than the non-farthest portion in the substantially central portion 13. Then, since the farthest part 34 is processed to be thick, the mechanical strength of the farthest part 34 can be improved, and as a result, the farthest part 34 can be broken and broken more than before.
- the double spiral glass tube processed to be thick so that the farthest portion 34 as described above is thicker than the non-farthest portion in the substantially central portion 13 is the embodiment. It can be manufactured by omitting the convex forming step in the above. That is, it is manufactured by the steps from FIG. 3 (a) to FIG. 4 (b).
- a double spiral glass tube has been described.
- the present invention is not limited to this, and the present invention is also applicable to arc tubes using 3 and 4 U-shaped bent glass tubes. it can.
- bulb-type fluorescent lamps have no outer tube glass bulb type, and lamp types are electric. Applicable to fluorescent lamps other than spherical, for example, compact, industrial applicability
- the present invention can be used for fluorescent lamps and the like.
