本発明は蛍光ランプ用ガラスに関し、特に環形蛍光ラン
プに好適なガラスに関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to glass for fluorescent lamps, and particularly to glass suitable for annular fluorescent lamps.
［従来技術とその問題点］
蛍光ランプは低圧水銀ランプが主として放射する紫外線
により蛍光物質を刺激して可視光を放射させるもので、
−ｍにガラス管の内壁に蛍光物質が塗ってあり、両端に
は電極が封じてあってその形状は直管形及び環形の二つ
に大別される。[Prior art and its problems] Fluorescent lamps use ultraviolet rays mainly emitted by low-pressure mercury lamps to stimulate fluorescent substances to emit visible light.
The inner wall of the glass tube is coated with a fluorescent material, and electrodes are sealed at both ends.
近年蛍光ランプは同一消費電力における全光束の向上の

物質の改良、バルブガラスの光透過率の改良が絶えず行
われており、より高効率の蛍光ランプが望まれており従
来より各種の組成からなる蛍光ランプが提案されている
が各々欠点がある。In recent years, in order to improve the total luminous flux of fluorescent lamps with the same power consumption, improvements have been made to the electrode structure, the type of gas filled in, the appropriate pressure, the fluorescent material, and the light transmittance of the bulb glass. Fluorescent lamps with high efficiency have been desired, and fluorescent lamps made of various compositions have been proposed, but each has its own drawbacks.

のは好ましくない。For example, in Japanese Patent Publication No. 52-33124, BaO and PbO
An annular fluorescent lamp is disclosed. It is true that containing these components has an excellent effect on reducing the viscosity of glass, but on the other hand, containing BaO causes significant corrosion to the refractories of the melting furnace, and containing PbO may pollute the environment. It is not preferable to contain these components.

透過しやすくなるため好ましくない。Furthermore, in JP-A No. 62-270234, F
A glass for a fluorescent lamp for a health line has been disclosed in which the transmittance at a wavelength of 300 on+ is increased to 40% or more by setting the content of e2O3 to 0.001 to 0.02%. In order to reduce the amount, the cost of raw materials for glass and the cost of iron removal in the glass manufacturing process become high, and ultraviolet rays of 260 nm or less, which are harmful to the human body, become more easily transmitted, which is not preferable.

The object of the present invention is to provide glass for fluorescent lamps, which has high hardness, excellent workability, can be produced at low cost, and has no fear of environmental pollution.

The present invention has been proposed based on the discovery that it is possible to improve the transmittance of visible light from 400 to 700 nn+ by strictly regulating the content of ≦, and to obtain glass with excellent workability at a low cost. In other words, the fluorescent lamp glass of the present invention has a weight percentage of TesiO□65.0 to 75.0% and Al2030.5.

It is characterized by consisting of 0.4~0.8% and Fe2O30.03~0.05%.
本発明において各成分の含有量を上記のように限定した
のは以下の理由による。The reason why the content of each component is limited as described above in the present invention is as follows.
ＳｉＯ２は、主要なガラス形成酸化物であるが、７５゜
０％より多い場合はガラスの溶解性が悪くなると共に失
透を生じやすくなって作業性が悪くなる。SiO2 is a major glass-forming oxide, but if it exceeds 75%, the solubility of the glass deteriorates and devitrification tends to occur, resulting in poor workability.
ｂ５．０％より少ない場合は耐水性が低下する。If b is less than 5.0%, water resistance will decrease.
Ａｌ２Ｏ３が２．５％より多い場合はカラスの溶解性が
悪くなり、０．５％より少ない場合は耐水性が低下する
。If Al2O3 is more than 2.5%, the solubility of glass will be poor, and if it is less than 0.5%, water resistance will be reduced.
Ｍｇｏが５．０％、ＣａＯがＬＯ％より多い場合は失透
を生じやすくなって作業性が悪くなり、両者の含量が９
５％より多い場合はＢ２Ｏ５との共存にょってガラスを
乳白化し易くなる。またＭｇＯカ月、０％、ＣａＯか３
，０％より少ない場合あるいは両者の合量が５．５％よ
り少ない場合は耐水性が悪くなる。If Mgo is more than 5.0% and CaO is more than LO%, devitrification tends to occur and workability becomes worse.
If it is more than 5%, the coexistence with B2O5 tends to make the glass opalescent. Also MgO month, 0%, CaO or 3
, 0% or the total amount of both is less than 5.5%, water resistance deteriorates.
Ｎａ２Ｏ、Ｋ２Ｏはガラスの溶解性を向上し、熱膨張係
数を上げる成分であるが、Ｎａ２Ｏが１９．０％以上あ
るいは両者の含量が２０．０％より多い場合は熱膨張係
数が高くなりすぎると共に耐水性が低下する。Na2O and K2O are components that improve the solubility of glass and increase the thermal expansion coefficient, but if Na2O is 19.0% or more or the content of both is more than 20.0%, the thermal expansion coefficient becomes too high and Water resistance decreases.
Ｎａ２Ｏが１３．０％より少ない場合は熱膨張係数が低
くなり過ぎガラスの溶解性が悪くなる。Ｎａ２Ｏの一部
をに２０で置換すると耐水性を向上させるが、に２゜が
３．０％より多い場合はガラスの粘度を上げガラスの溶
解性が悪くなる。When Na2O is less than 13.0%, the coefficient of thermal expansion becomes too low and the meltability of the glass deteriorates. If a part of Na2O is replaced with 20, water resistance is improved, but if 20 is more than 3.0%, the viscosity of the glass increases and the solubility of the glass deteriorates.
Ｂ２Ｏ３はカラスの高温粘度を低下させ、耐水性を向上
させる効果があるが、３．０％より多い場合はガラス溶
解中に揮発物が増大する。Ｏｊ％より少ない場合は上記
効果が得られにくい。B2O3 has the effect of lowering the high-temperature viscosity of glass and improving its water resistance, but if it exceeds 3.0%, volatile matters increase during glass melting. When the amount is less than Oj%, the above effects are difficult to obtain.
Ｐ２Ｏ，は液相温度を低下させる効果があるが、１０％
より多い場合はガラスの乳白化が生じ易くなる。０．１

If the amount is higher than that, opalescence of the glass is likely to occur. 0.1

くない。As described above, the present invention aims to obtain glass for fluorescent lamps with excellent transmittance in the visible light region, workability, and productivity.
203 at 0.4-0.8%, Fe2O30.03-0.
The content is strictly controlled at 0.05%. i.e. 5b20
3 has the effect of improving the transmittance of visible light in the 400-700 nm range and making it easier to remove bubbles from the glass, but if it exceeds 0.8%, crystals caused by antimony are likely to occur and the glass tube This is not preferable because it lowers the yield and increases the cost of raw materials. Further, if it is less than 0.4%, the above effects cannot be obtained. F
Since e2O3 lowers the transmittance of visible light, especially of visible light below 500 nm, it is preferable to keep its content as low as possible, but if it is 0.05% or less, the effect of reducing transmittance is almost negligible. In order to avoid this and reduce the content to less than 0.03%, the cost of raw materials for glass and the cost of removing iron in the glass manufacturing process will increase.
This is not preferable because harmful ultraviolet rays of nm or less become easily transmitted.
