Abstract

PURPOSE:To remove a cloudiness phenomenon to be produced on the inner wall of an outer tube as well as to make a distinct improvement in luminous flux, by constituting the inner tube of a compact size fluorescent lamp making the inner tube a discharge passage with glass whose constituent parts of sodium is below the specified value. CONSTITUTION:More than one spot of interconnecting parts in each of plural pieces of bent tubes 2 are open to the inside of a hermetic space to be formed by both of an outer tube 1 and a stem 4, while each electrode is installed in both sides of each of the said inner tube 2 made up in series, making these inner tubes 2 a discharge passage. The said inner tube 2 in a suchlike fluorescent lamp is constituted of glass whose constituent parts of sodium is below 10%. With this constitution, a cloudiness phenomenon that happens on an inner wall of the outer tube is hard to be gathered so that a tendency toward a drop in luminous flux can be sharply improved so better as approximating to almost nothing.

The lamp part A consists of an outer tube 1, a U-shaped inner tube 2, a spacer 6, and a stem 4. The inner wall of the inner tube 2 is coated with a phosphor 5 and fired. Six inner tube insertion holes 7a to 7f having counterbore portions 6 for positioning and fixing both ends are provided, and six inner tube insertion holes 7a to 7f are provided.
Insertion holes 7 adjacent to each other among the 4th human holes 7a to 7f
The holes a and 7b are connected to each other by a communication hole 8 whose upper and lower surfaces are open, and the other adjacent insertion holes 7d and 7e are connected by a communication groove 9 which is opened only at 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 inner tube 2 common.

Next, let's move on to assembly. First, after fitting both open ends of each inner tube 2 into the counterbore portions 6 of the inner tube insertion holes 73 to 7f, the spacer Fix it airtight. This airtight fixing is necessary to reduce the gap that occurs between the outer wall of the inner tube 2 and the counterbore 6 of the spacer B, and there is nothing that requires airtightness.Next, in this way, Inner tube 2
A spacer 6 integrated with the stem 4, both electrodes 16 and 16 provided on the stem 4, and an encapsulated wire 12 for fixing the O-spacer.
However, the inner tube insertion hole 7ζ7f provided in the spacer 6 and the enclosed i
They are arranged so as to correspond to the insertion grooves 10, respectively. The spacer 6 and the stem 4 are fixed by an enclosed wire 12 for fixing the spacer.
This is done by bending the spacer B in the upper surface direction. In this step (1'), the free electrode 11 and each inner tube 2 are connected in series to form one discharge path. Fixing the spacer 6 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, the lamp part A is constructed by performing the usual electrode material activation process, exhausting, and charging gas for discharge from the exhaust pipe 14. Therefore, the inner tube 2 of the fluorescent lamp as described above is made of soda glass (Si02 near 0%, to A2 (J, ky20
: 18%, MgO, CaO: 8%, etc.), the disadvantage is that the outer tube 1 becomes cloudy inward in a relatively short period of time, the passage rate decreases, and the luminous flux decreases in a short period of time. I was disappointed. In other words, when applying 16"V of human power, the temporal variation of the luminous flux rapidly decreases to 4 pieces.

Furthermore, when chemical analysis was performed, gold 1p4 mercury was detected from the cloudy part, and an increase in sodium (Na) content was observed. Therefore, the mechanism of white ~ can be 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 chamber formed by the outer tube 1 and the inner tube 2. This near ultraviolet light causes Na to be liberated on the inner wall of the outer canal and the outer wall of the inner canal.
