Abstract

PURPOSE:To effectively improve a method of applying a phosphor coating to the bulb of a curved tube and drying it while the bulb is being rotated or revolved. CONSTITUTION:A phosphor coating is applied by coating the wall surface in the bulb 1 of a curved tube with a phosphor liquid. Then the above-mentioned phosphor liquid is discharged from both tube ends 3 and 3. In this case, since the phosphor coating is not dried, excessive phosphor liquid is collected at the central curved section 2 of the bulb by supporting the bulb 1 of the curved tube with both tube ends 3 and 3 facing downward. Then the bulb 1 of the curved tube is rotated around the first axis 4 that connects the approximate central section between both tube ends 3 and 3 and the central curved section 2 to the center of gravity G of the bulb 1 of the curved tube, that is, it is revolved on its own axis. Simultaneously with this rotary motion, this first axis 4 is revolved around the second axis 5 that intersects with this axis 4 at a right angle and passes through the center of gravity G. The phosphor coating is dried without collecting the excessive phosphor liquid in one place by this composite motion. Then the dried phosphor coating is baked.

TECHNICAL FIELD OF THE INVENTION The present invention relates to a method of forming a phosphor coating for a fluorescent lamp.

[Technical Background of the Invention and Problems Therewith] Conventionally, the method for forming curved tube-shaped curved light lamps has been to form a phosphor coating on straight tube pulp and then bend the pulp.

However, this method has the disadvantage that the phosphor coating cracks during pulp formation, resulting in not only an unsightly appearance but also a decrease in performance. In particular, in the case of a fluorescent lamp with a roughly shaped fluorescent lamp consisting of four straight tube-like legs and three U-shaped parts, which form a single discharge path as a whole, the conventional annular fluorescent lamp is used. Compared to lamps, the degree of curvature is greater, and the phosphor coating is more likely to crack.

On the other hand, when forming a phosphor coating on a straight tube bulb by bending it into a desired shape, applying a phosphor solution to bent tube pulp with a complex pulp shape such as a saddle-shaped fluorescent lamp , surplus fluorescent body fluid.

Even if a material such as pulp is used, it tends to accumulate in the curved part, making it impossible to sufficiently drain excess fluorescent body fluid. For this reason, the formed phosphor film has the disadvantage that the film thickness is non-uniform. One way to overcome this drawback is to attach a thin tube.

In other words, a thin tube for draining excess fluorescent body fluid is attached to the place where excess fluorescent body fluid accumulates, and the excess fluorescent body fluid is discharged through this thin tube to uniformize the thickness of the fluorescent body coated on the inner wall surface of the pulp. This is the way to do it.

However, this method requires more work to attach the capillary to the bent pulp pulp, and also adds the work of sealing the capillary after the phosphor is coated on the inner wall of the pulp.

It is time-consuming, and the part where the thin tube is attached is weak and easily cracks. Therefore, the applicant first coated the inner wall of the pulp with a light coating on the inside of the bent tube, and then removed the pulp. A method of drying a phosphor film without rotating or rotating the phosphor film has been filed. According to this method,
Since the phosphor coating is dried without rotating or rotating the pulp, it is possible to eliminate the disadvantage that excess phosphor fluid accumulates in one place and the film becomes too thick.

The method for forming a phosphor coating on the above bent pipe pulp (1) is as follows. First, the fluorescent body fluid was extracted from bent tube pulp (
1) Apply one coat to the inner wall surface and apply a light coating. The fluorescent body fluid is a liquid mixture made by mixing a fluorescent material and a 100% liquid in a solvent such as methyl acetate. The fluorescent body fluid is then discharged from both tube ends (3), (3). At this time, the phosphor coating is not dry, so if you support the one-bent tube bulb (1) so that both tube ends (31, The bent pipe pulp (1) is collected at both pipe ends (31,
(Rotate or rotate about the first axis (4) that connects the approximate center of the central curved part (2) and the center of gravity G of the two-bent pipe pulp (1). Simultaneously with this rotational movement, the The first axis (4) is rotated around a second axis (5) that is perpendicular to this axis (4) and passes through the center of gravity G. Due to this compound movement, excess fluorescent body fluid accumulates in one place. The phosphor coating is then dried.The dried phosphor coating is then baked.This step is performed to remove impurities contained in the phosphor coating.

If the first axis (4) is parallel to the vertical line, it is obvious that excess fluorescent body fluid will accumulate in the central curved portion (2). Furthermore, if the first axis (4) is perpendicular to the vertical line, excess photofluid will not accumulate in the central curved part (2) when it is parallel to the vertical line; The excess fluorescent body fluid near the part (2) does not spread toward the straight part of the pulp. However, two axes (41, (5)
By applying a motion that is a combination of the rotational motions of the pulp to the bent pipe pulp, the excess light body fluid does not accumulate in one place and is spread uniformly over the entire inner wall surface of the pulp. Here, in order to prevent the remaining light body fluid from accumulating in one place,
Rotational motion around two axes (41, +51 that are orthogonal to each other is sufficient. Therefore, the first, second, and @(4
