Abstract

PURPOSE:To facilitate treatment of two lead wires and obtain a lamp with excellent quality by prefixing a metal wire between the two lead wires spaced at preset intervals and disconnecting the lead wires at the location where the metal wire can be removed after pinch sealing. CONSTITUTION:A metal wire 6 is prefixed between two lead wires 4 and two sets of electrodes to which filaments 2 are connected and an exhaust tube 5 are inserted in a flare and then each filament 2 is set by inserting an inner tube 1 at the center from above. In this state, rotation is performed centering around the exhaust tube 1 and the flare 3, inner tube 1, and the exhaust tube 5 are heated and softened with a burner 8, pinch sealing is performed by a pressing piece 7 that advances from the horizontal direction. As a result, the lead wires 4 of a metal conductor, vitreous inner tube 1, flare 3, and exhaust tube 5 are fused integratedly. Then, the lead wires 4 are cut at the position where the metal wire 6 can be removed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a method for manufacturing a self-ballasted fluorescent lamp, and more particularly to a method for manufacturing a mount for this type of lamp.

[Background of the invention]

When making a vertical line of filament between two lead-in wires, crush the part of the lead-in wire that corresponds to the position where the filament will be vertically drawn, and the lead-in wire will rotate during the bending process, making the bending uncertain and causing the filament to bend. Vertical lines become difficult. Furthermore, when a finished product with vertical filament lines is transported, the lead-in wire rotates due to the coiling of the filament, making it difficult to maintain the precision of the lead-in line spacing. -Changes in the lead-in line spacing directly affect the state of the filament's vertical lines. , which has a negative effect on lamp characteristics.

[Purpose of the invention]

Therefore, an object of the present invention is to provide a method for manufacturing a compact fluorescent lamp that can solve these problems.

[Summary of the invention]

In order to achieve the above object, in the present invention, the lead-in wire of the mount component and the filament are fixed in advance with a metal wire with a predetermined distance between the two lead-in wires in a previous step, and Make a vertical line through the filament. Thereafter, the flare, exhaust pipe, and multiple inner pipe mount components are heated and softened from the outer periphery of the flare body using a burner, and then pinch-sealed. Considering post-processing, the lengths of the multiple lead-in wires extending outside the mount should be constant, and it is also necessary to remove the metal wires. By cutting the lead-in wire at a position where the metal wire can be removed during the mount manufacturing process, it is possible to manufacture a compact fluorescent lamp mount in which the metal wire is removed and the lead-in wire extending outside the mount has a constant length.

[Embodiments of the invention]

Embodiments of the present invention will be described below with reference to FIGS. 1, 2, 3, and 4.
This will be explained using figures.

FIG. 1 shows a basic configuration diagram of a mount for a self-ballasted fluorescent lamp manufactured by the manufacturing method according to the present invention. FIG. 2 is a diagram illustrating the arrangement of mount components before being formed into a mount. As shown in Fig. 1.2, in the previous step, the space between the two lead-in M4s is fixed with a metal wire 6, and in that state, the two sets of electrodes with the filament 2 as a vertical line and the exhaust pipe 5 are inserted into the flare 3. , and insert and set the inner tube 1 from above centering each filament 2. In this state, it rotates around the exhaust pipe 5, heats and softens the flare 3, inner pipe 1, and exhaust pipe 5 with the burner 8, and performs pinch sealing with the pressing pieces 7 that enter from the left and right directions. As a result, the metal conductor lead-in wire 4, the glass inner tube 1, the flare 3, and the exhaust pipe 5 are fused into one body. Furthermore, the mount shown in FIG. 1 is obtained by cutting the metal wire 6 between the lead-in wires 4 at a position where the metal wire 6 can be removed.

FIG. 3 is a basic configuration diagram of a compact fluorescent lamp manufactured using the mount manufacturing method of the present invention.

This is a flare 3 of a mount which has an outer tube bulb 9 with a diffuser film formed on the inner surface and an inner tube 1 with a fluorescent film formed on the inner surface.
It is sealed on the collar of the.

FIG. 4 shows an applied example of the method of fixing between the lead-in lines 84, in which one lead-in line 4, 4' is bent to form a vertical line. In this case as well, if the lead-in 1t14 is cut at a position where the bent portion can be removed, the mount shown in FIG. 1 can be obtained.

〔Effect of the invention〕

As described above, according to the present invention, the metal wire can be removed during the mount manufacturing process and the length of the lead-in wire on the outside of the mount can be made constant, thereby ensuring filament disassembly during the exhaust process and when attaching the cap. This makes it easier to handle the lead-in wire, and it is possible to manufacture high-quality compact fluorescent lamps at low cost.
