(Background technology) In recent years, against the backdrop of energy conservation, in the field of light sources, the principle of fluorescent lamps, which have the great advantages of high efficiency and long life, has been used to replace the principle of fluorescent lamps, which have the fatal drawbacks of low efficiency and short life. A compact fluorescent lamp that can replace an incandescent light bulb is being actively studied.

FIG. 1 shows an example of a conventional fluorescent lamp of this type.Inside the airtight space formed by the outer tube 1 and the stem 2, there is a U-shaped inner tube 4 whose inner surface is coated with a fluorescent material 3. is housed through a holder 5 fixed to the stem 2, and the inside and outside of the inner tube 4 are connected to the holder 5.
The same airtight space is formed by the opening 6 provided in the
A predetermined amount of mercury vapor and rare gas are sealed within the space. Then, the discharge occurs between the inner tube 4 and the holder 5.
The discharge is performed between a pair of electrodes 7 disposed at both ends of a discharge path regulated by a communication path (not shown) provided in the discharge path. In addition, in the figure, 8 is a lighting device part in which a ballast etc. are built in, and 9 is a screw cap.

Therefore, in the inner tube 4 of the fluorescent lamp as described above,
When glass with a high sodium (Na) content, such as soda glass, is used, as the lamp lighting time elapses, a cloudy phenomenon occurs throughout the inner wall of the outer bulb 1, resulting in a significant decrease in the lamp light output. This is because the sodium (Na) component in the glass constituting the inner tube 4 scatters due to the heat and ultraviolet rays from the discharge and adheres to the inner wall of the outer tube 1, and then reacts with the mercury vapor inside the tube. It is presumed that this is due to the formation of an amalgam.

Therefore, if borosilicate glass with a sodium (Na) content of about 3 to 10% is used for the inner tube 4, which has a lower sodium (Na) content than soda glass, the above-mentioned cloudiness will not occur near the electrode 7, which is the highest temperature. This can be improved so that only the inner surface of the outer tube 1 is present. Furthermore, if quartz glass containing almost 0% sodium (Na) is used, this clouding phenomenon will not occur at all. However, quartz glass has a problem in that it is inferior to borosilicate glass in terms of workability and cost, and is therefore impractical.

(Purpose of the invention) The present invention was devised in view of the above points, and its purpose is to prevent the clouding phenomenon that occurs on the inner surface of the outer tube near the electrodes, and to improve workability during the manufacture of the inner tube. The purpose is to provide an undamaged fluorescent lamp.

(Disclosure of the invention) Fig. 2 shows an embodiment of the invention, which differs from the configuration of the conventional example in that the diameter of the inner tube 4 is increased only near the electrodes, and the other configurations are different from that of the conventional example. Since they are equivalent, the description will be omitted by assigning the same reference numerals to the equivalent parts.
