る。(Background Art) Part 1 is a perspective view showing a conventional fluorescent lamp, which is comprised of a lamp part A, a lighting device part B, and a screw cap part C. Part 2 I is an exploded perspective view of the lamp part A. The lamp part A consists of an outer tube 1, a U-shaped inner tube 2, a spacer 3 and a stem 4,
A phosphor 5 is coated on the inner wall of the inner tube 2 and fired.
The spacer 3 is provided with six inner tube insertion holes 7a to 7f each having a counterbore s6 for positioning and fixing both ends of the inner tube 2. Of the six inner tube insertion holes 7a to 7f, the insertion holes 7a and 7b that are adjacent to each other are communicating holes 8 with -L lower surfaces open, and the other adjacent insertion holes 7d and 7c
are connected to each other by a communication groove 9 that is open only on the lower surface. The reason for providing the communication hole 8 is to make the space formed by the outer tube 1 and the stem 4 and the discharge space of each of the inner tubes 2 common. Reference numeral 10 denotes a spacer fixing encapsulating wire insertion groove for fixing the spacer 3 on the stem 4. stem 4
4 wooden lead wires 11 and 4 wooden spacer fixing enclosed wires 12 are enclosed, and an electrode 13 is attached to the tip of the lead wire 11. Note that 14 is an exhaust pipe.

First, both open ends of each inner tube 2 are fitted into the counterbore portions 6 of the inner tube insertion holes 7a and 7f, and then attached to the spacer 3 using an adhesive such as a heat-curable heat-resistant inorganic adhesive or glass frit. Fix airtightly. This airtight fixation does not necessarily require airtightness as long as the gap created between the outer wall of the inner tube 2 and the counterbore 6 of the spacer 3 is made small. Next, the spacer 3 integrated with the inner tube 2 in this way is attached to the stem 4, and both electrodes 13, 13 and the spacer fixing encapsulated wire 12 provided on the stem 4 are attached to the stem 4.
An inner tube insertion hole 7c provided in the spacer 3.

。7f and the enclosing wire insertion groove 10, respectively. The spacer 3 and the stem 4 are fixed to each other by bending the spacer fixing encapsulating wire 12 inward toward the upper surface of the spacer 3. Through this process, the electrode 11 and each inner tube 2
are connected in series to form one discharge path. Fixing the spacer 3 to the stem 4 does not necessarily require airtightness as long as the gap is made small. After the open end of the outer tube 1 and the outer periphery of the stem 4 are hermetically sealed,
From the exhaust pipe 14, the normal electrode material activated ripened egg, exhaust, and release.
The lamp part A is completed by filling the gas for 1.

欠点があった。即ち、IRW入力を与えた場合の発光束
の時間的変化を示すと、という形で急速に低下する。In this case, the inner surface of the outer tube 1 becomes cloudy in a relatively short period of time, resulting in a decrease in transmittance, which has the disadvantage that the luminous flux decreases in a short period of time. In other words, the temporal change in luminous flux when IRW input is applied shows that the luminous flux rapidly decreases in the following manner.

外壁にてNaの遊離が起る。Considering the mechanism of the cloudy phenomenon that occurs on the inner wall surface of the outer tube 1, when the outer tube glass in which the cloudiness occurred was observed, it became clear that particles in the form of substances were aggregated in the cloudy area. Further, when chemical analysis was performed, metallic mercury was detected from the cloudy part, and an increase in sodium (Na) component was observed. Therefore, the mechanism of cloudiness is considered as follows. That is, among the ultraviolet rays generated by the discharge within the tube, near ultraviolet rays pass through the soda glass forming the inner tube 2 and reach the non-discharge space formed by the outer tube 1 and the inner tube 2. This near ultraviolet light causes Na to be liberated from the inner wall of the outer tube and the outer wall of the inner tube.
