関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a compact fluorescent lamp having a double tube structure in which a bent inner tube is housed in a discharge space formed by an outer tube and a button stem.

れている。 Against the background of energy conservation in recent years, in the field of light sources, we are using the principles of optical lamps, which have the great advantages of high efficiency and long life, to replace incandescent light bulbs, which have the fatal disadvantages of low efficiency and short life. Fluorescent lamps with a transparent and compact structure are being actively studied.

装置部、９はねじ口金である。 In line with this trend, the present application was previously filed for a compact fluorescent lamp having a structure as shown in FIG. That is, the outer tube 1 and the button stem 2
A fluorescent lamp in which two U-shaped inner tubes 4 are housed in a discharge space 3 kept airtight by
A phosphor 5 is coated on the inner surface of the U-shaped inner tube 4, and one end of the inner tube 4 is hermetically fixed around an electrode 6, and the other open end 7 is used to connect both sides. A discharge occurs between the electrodes 6,6. In addition, in the figure, 8 is a lighting device part, and 9 is a screw cap.

率、コスト等の面でこの操作は好ましくない。 However, the above-mentioned compact fluorescent lamp has the following problems in its performance. In other words, since the above-mentioned lamp has a double tube structure, the temperature of the inner tube (including the U-shaped inner tube 4 and internal parts of the lamp) does not rise sufficiently during baking during the exhaust process during lamp manufacturing. Due to the multi-tube structure, heat transfer to the inner tube is poor, and heating baking from the outside creates a large temperature difference between the outer tube 1 and the inner tube).Therefore, the exhaust efficiency is poor, and a large amount of adsorbed impurity gas is trapped inside. The lamp will be tipped off leaving it in the tube. Of course, if the evacuation time is greatly increased, the temperatures of the outer tube 1 and the inner tube will gradually approach each other and the desired evacuation efficiency can be obtained, but this operation is not preferable in terms of manufacturing efficiency, cost, etc.
この結果、残留不純ガスの影響で、 電極６近傍の管壁の黒化が著しい。 As a result, due to the influence of residual impurity gas, There is significant blackening of the tube wall near the electrode 6.
けい光体５の光束減退率が大きい。 The luminous flux attenuation rate of the phosphor 5 is large.
ランプ寿命が短かい。 Lamp life is short.

る。 Hereinafter, the present invention will be explained based on illustrated embodiments. FIG. 2 is a perspective view showing the fluorescent lamp section according to the present invention, and FIG. 3 is an enlarged sectional view of the inner tube, which has almost the same structure as the conventional one. In the manufacturing process, first, SnO 2 (tin oxide) is applied to the inner or outer wall of the inner tube 4.
A transparent conductive film 10 made of a film or an In 2 O 3 (indium oxide) film is formed, and then a phosphor 5 is applied to the inner wall of the inner tube 4 and baked to adhere thereto. Next, the inner tube 4 is placed around the electrode 6 on the button stem 2 by a method such as gluing or sealing. Then, the outer tube 1 is sealed to the end face of the button stem 2, and the exhaust pipe 11 is connected to the exhaust system (Fig. (not shown) to evacuate the lamp. For baking during this evacuation, if high-frequency induction heating is performed in addition to heating with a normal gas flame, since the inner tube 4 is coated with the conductive coating 10, it will be rapidly heated and the evacuation efficiency will be good. Next, the electron radioactive material applied to the electrodes 6 is activated, and a predetermined amount of mercury and inert gas are sealed, and then the exhaust pipe 11 is tipped off to complete the lamp.

く本発明は適用できる。 Note that the high-frequency induction heating is continuously performed until just before the filling of mercury and inert gas. Further, in this embodiment, a lamp consisting of two U-shaped inner tubes 4 has been described, but the present invention can be applied regardless of the number and shape of the inner tubes 4.

As a result, as shown below. Thus, an improved fluorescent lamp could be obtained.

たけい光ランプを提供できた。(1) As shown in Figure 4, blackening of the tube wall near the electrodes was significantly suppressed. (In the figure, A is the measured value with the lamp according to the present invention, B is the measured value with the conventional product, and the blackening rate on the vertical axis is level 5 is no blackening, and the smaller the number, the greater the blackening. (2) The luminous flux attenuation rate of the phosphor 2 has been improved. (See Figure 5) (3) Lamp life has been increased by more than 1.5 times from the conventional approximately 4,000 hours to over 6,000 hours. (See Figure 5) (In Figure 5, A is the measured value with the lamp according to the present invention, and B is the measured value with the conventional product.) Next, in order to further improve the exhaust efficiency, the above exhaust process Perform high frequency induction heating at
Additionally, mercury may be introduced into the lamp to cause high-frequency electrodeless discharge. The mercury is led into the lamp through the exhaust pipe 11 immediately after the start of evacuation, and the inner tube is also rapidly heated as the mercury ions generated by the high-frequency electrodeless discharge strike the inner tube wall. Therefore, it was possible to further improve the exhaust efficiency and provide a fluorescent lamp with an improved lamp life of about 6500 hours compared to the previous example.
