Abstract

PURPOSE:To produce fluorescent lamps with low cost while saving resource and energy, by employing such soda rime glass where iron oxide is less than 0.2wt% while the weight ratio between bivalent and trivalent irons is at least 0.3 for the exhaust tube of stem. CONSTITUTION:The glass flare 1 is supported by a holder while the glass exhaust tube 2 supported by another holder is arranged at the predetermined position of flare 1 which is inserted with lead wires 3, 3. The lower portion of flare 1 is thermally softened by gas burners 4, 4 then collapsed to seal the lead wires 3, 3. The exhaust tube 2 is composed of soda rime glass where iron oxide is less than 0.2% while the weight ratio between bivalent and trivalent irons is at least 0.3. In such a manner, fluorescent lamps can be produced with low cost while saving resource and energy. When composing the flare 1 with soda glass of same composition, the yield can be improved with lower cost.

Traditionally, soda lime glass was used for straight tubes, and lead glass was used for ring and curved tubes to make glass pulp, the light-transmitting airtight container for fluorescent lamps. The reason why lead glass was used for the glass pulp of ring-shaped or curved fluorescent lamps is that it could be easily heat-processed when forming it into a ring or curved tube shape. It was a lead glass containing about f4'%. However, this lead glass uses a large amount of lead oxide, which is an expensive raw material, as mentioned above, which increases the price of the glass and, in turn, increases the manufacturing cost of fluorescent lamps such as ring and curved tubes. Na(
However, since it contains lead, which causes pollution, there is a problem in the disposal of discarded lamps. Therefore,
Soda lime glass, which has conventionally been used in straight tube fluorescent lamps, is also being used in ring-shaped and curved tube-shaped fluorescent lamps. In this way, when soda lime glass is used for the glass pulp of the airtight container, molding and heating processing can be easily performed if the conventional lead glass mentioned above is used for the stem supporting the electrode structure, but as mentioned above, the glass pulp cannot be heated. Because it uses lead, which is expensive and causes pollution, there is a problem with its disposal, so research was conducted on using soda lime glass instead of lead glass (-) in stems. However, compared to conventional lead glass, The softening temperature of soda lime glass is approximately 80°C higher than that of lead glass (therefore, the heating processing temperature must also be approximately 100°C). If the heating processing temperature is high, the coal gas used for heating processing will It saves resources as it does not require the use of a lot of electricity or electricity.

In the present invention, the exhaust pipe of the stem is made of soda-lime glass, and the soda-lime glass has a total amount of iron oxide of less than 0.2% (1%), which is a combination of divalent iron and trivalent iron. A fluorescent lamp characterized in that the weight ratio is at least 0.3, which uses less expensive lead glass, is therefore inexpensive, and furthermore does not cause the glass to be colored.
In addition, since the processing temperature can be suppressed during heating processing, processing can be performed at each station, and furthermore, the flexible plate should be made with a weight ratio of divalent iron to trivalent iron of at least 0.3. Preferably 0.5
By using this glass, it is possible to provide a fluorescent lamp that is cheaper, saves resources and energy, and has the special effect of improving the yield of the fluorescent lamp manufacturing process.
