最近、白熱電球に代わる省エネルギー光源として、種々
の電球形螢光ランプが製品化されている。2. Description of the Related Art Recently, various light bulb-shaped fluorescent lamps have been commercialized as energy-saving light sources to replace incandescent light bulbs.

に維持するかが技術上のポイントとなる。These lamps have, for example, a nine-fold arc tube built into the outer bulb globe, which causes the temperature of the arc tube to rise excessively compared to ordinary fluorescent lamps. As a result, the mercury vapor pressure within the arc tube during operation becomes higher than the optimum level from the luminous flux plane, and the luminous flux decreases. Therefore, in order to realize a particularly high luminous flux type of this type of bulb-shaped fluorescent lamp, the technical point is how to maintain the mercury vapor pressure at an optimum level.

ガム中の水銀は、ランプ始動時の電極加熱温度で速やか
に蒸発してランプ光束を急速に立ち上がらせる。The amalgam method has been put into practical use as one method for regulating mercury vapor pressure. This method uses mercury in the arc tube as indium (In) or bismuth-indium (Bi).
-In), lead-bismuth-tin (pb-Bi-8n), etc. in the form of an amalgam to regulate the vapor pressure of mercury to an optimal level even if the arc tube temperature rises excessively. . Usually, this method employs a so-called double amalgam method in which amalgam is sealed in the glass tube of the stem sealed at both ends of the arc tube and in the vicinity of the electrodes. Among these, the amalgam sealed in the glass capillary is called the main amalgam, and is used to regulate the mercury vapor pressure during steady lighting to an optimal level from the light beam plane. On the other hand, the amalgam sealed in the vicinity of the electrode is called auxiliary amalgam, and is intended to improve the drawback that if only the main amalgam is used, the mercury vapor pressure at room temperature is too low and the luminous flux rises slowly after lighting. The mercury in the auxiliary amalgam quickly evaporates at the electrode heating temperature when starting the lamp, causing a rapid rise in the lamp luminous flux.

る。When the temperature of the arc tube rises when the lamp is turned on, this mercury reacts with the main amalgam, and at room temperature when the lamp is off, it returns to the auxiliary amalgam-forming metal, repeating the cycle, and the auxiliary amalgam exhibits its effect each time it is lit. do.

ことができた。Problems to be Solved by the Invention In light bulb-shaped fluorescent lamps that adopt the double amalgam system, the luminous flux of the lamp during steady operation is significantly improved compared to lamps filled with only mercury due to the regulation of mercury vapor pressure by the main amalgam. In addition, the lamp luminous flux was able to rise rapidly due to the rapid evaporation of mercury during startup using the auxiliary amalgam.

すくなるためであることを見い出し友。However, the inventors have discovered that among such double amalgam lamps, there is a probability that there is a lamp whose luminous flux rise characteristic deteriorates during long-term operation. The inventor studied this phenomenon in detail and found that when the lamp is turned on, the temperature of the auxiliary amalgam and the internal lead wire to which it is fixed becomes high. This is because the nickel penetrates through the nickel layer into the nickel layer of the internal lead wire made of nickel-plated iron wire, forming an alloy, and the function of the auxiliary amalgam decreases. This occurs early when the internal lead wire is connected to the power supply side of the lighting device; this is because in this connection, at the beginning of its life, the electrode bright spot is located at the end of the electrode coil near the internal lead wire on the side where the auxiliary amalgam is adhered. The inventor discovered that this is because the internal lead wire becomes extremely high temperature due to heat conduction from the electrode bright spot, making it easy to react with indium.

った。According to the inventor's measurements, when the internal lead wire is connected to the so-called starting device side of the lighting tube, the temperature at the connection between the internal lead wire and the auxiliary amalgam of the lamp at the beginning of its life is approximately 22
'0°C, whereas the same temperature when the internal lead wire was connected to the power supply side was much higher at about 500°C.

のである。The present invention provides a self-ballasted fluorescent lamp that prevents functional deterioration of the auxiliary amalgam due to alloy formation between the auxiliary amalgam-forming metal and the internal lead wire, and that maintains excellent luminous flux rise characteristics over a long period of time up to the lamp's lifespan. This is what we provide.

きる。In this configuration, if the amount of electrode emitter is sufficient for the life time, at the end of life, no electrode bright spot will be formed at the end of the electrode coil near the internal lead wire attached with the auxiliary amalgam. During this time, the temperature of the internal lead wire is kept low, suppressing functional deterioration of the auxiliary amalgam due to alloy formation with the auxiliary amalgam-forming metal, and excellent luminous flux rise characteristics can be maintained throughout the life of the lamp.

The movement characteristics of the rise 9 of the luminous flux were measured. The results are calculated based on the lighting 1 for the maximum luminous flux value.
It is shown in FIG. 3 as a ratio of luminous flux values after minutes.
