Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は螢光灯の予熱構造に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to a preheating structure for a fluorescent lamp.
本発明は、螢光灯の外周に取り付けた予熱用の導電膜に
より、低温時に螢光灯全体を即座に予熱し、輝度を向上
させることができるものである。The present invention is capable of instantly preheating the entire fluorescent lamp at low temperatures and improving its brightness by using a preheating conductive film attached to the outer periphery of the fluorescent lamp.

熱陰極放電となるのである。ここで、６は主要回路であ
る螢光灯放電回路である。A conventional preheating device for a fluorescent lamp is shown in FIG. When the fluorescent lamp 2 is a hot cathode fluorescent lamp, the cathode must be heated in advance in order to generate a stable hot cathode discharge. The preheating filament 5 and filament preheating circuit 7 play the role of cathode heating. Immediately before discharge, an AC voltage or a DC voltage is applied to the filament 5 by the filament preheating circuit 7. As a result, the filament 5 serving as the cathode is heated, and a hot cathode spot is formed almost simultaneously with the discharge, resulting in stable hot cathode discharge. Here, 6 is a fluorescent lamp discharge circuit which is a main circuit.
中に水銀を封入し、水銀ガスから励起される紫外線を可
視光に変換させるタイプの螢光灯には、宿命とも言うべ
き低温での輝度低化がある。これは、低温での水銀ガス
の蒸気圧が低下することによるものである。Fluorescent lamps that contain mercury and convert the ultraviolet light excited from the mercury gas into visible light suffer from a fateful decline in brightness at low temperatures. This is because the vapor pressure of mercury gas decreases at low temperatures.
周囲温度が低温であやでも、放電後充分に時間が過ぎて
いて蛍光灯が放電電力により充分に熱せられているとき
は上述の問題はあまりない。ｒＭ囲湿温度低くて、なお
かつ放電直後の蛍光灯は冷えていて、そのための輝度低
下が問題なのである。Even if the ambient temperature is low and foggy, if a sufficient amount of time has passed after discharge and the fluorescent lamp is sufficiently heated by the discharge power, the above-mentioned problem does not occur much. The problem is that the rM ambient temperature is low and the fluorescent lamp is cold immediately after discharge, resulting in a decrease in brightness.
従来の蛍光灯の予熱装置では、陰極のフィラメント５だ
けを加熱することができても、蛍光灯２全体を加熱する
ことはできない。中の水銀の温度を上げるには、内壁全
体の温度を上げなければならないの、である。In the conventional fluorescent lamp preheating device, only the cathode filament 5 can be heated, but the entire fluorescent lamp 2 cannot be heated. In order to raise the temperature of the mercury inside, the temperature of the entire inner wall must be raised.
本発明の目的は、蛍光灯が冷えているときに、般小のパ
ワーで、できるだけ早く蛍光灯全体を暖め、充分な輝度
を得ることにある。An object of the present invention is to warm up the entire fluorescent lamp as quickly as possible with a small amount of power when the fluorescent lamp is cold, and to obtain sufficient brightness.
本発明は、透明導［膜または金属膜などの抵抗をもやだ
導電膜を、蛍光灯の外側の一部または全周にスパッタま

とすることを特徴とする。The present invention provides a method of attaching a transparent conductive film or a conductive film that has no resistance, such as a metal film, to a part or the entire outer circumference of a fluorescent lamp by sputtering, coating, pasting, etc., and using it as a heat generation source for preheating. It is characterized by

ス管内壁の温度で決まる水銀蒸気圧も向上する。よって
、水銀ガスからの励起紫外線の量も増加し、故に輝度も
向上する。By heating the heat source of the m-guide film attached to the outer periphery of the fluorescent lamp, the entire glass tube of the fluorescent lamp is warmed, and the mercury vapor pressure, which is determined by the temperature of the inner wall of the glass tube, also increases. Therefore, the amount of excited ultraviolet rays from the mercury gas also increases, and therefore the brightness also improves.

膜の両端から予熱用回１Ｉ２ｓ５に電気的に接続する。FIG. 1 shows a fluorescent lamp preheating device according to an embodiment of the present invention. First, a conductive film 1 such as a transparent conductive film or a metal film having a resistance value necessary for heat generation is attached to a part or the entire circumference of the outside of the fluorescent lamp 2 mainly by sputtering or the like. Next, both ends of the conductor membrane are electrically connected to the preheating circuit 1I2s5.
予熱用回路６は、導電膜１の両端にＡＣ電圧またはＤＣ

１ｉ膜１で工２Ｒの電力が消費され、導電膜１が発熱す
る。導！！膜１と蛍光灯のガラス管は密着しているため
、熱が効率良くガラス管に伝わり、中の水銀蒸気圧が上
がるのである。The preheating circuit 6 applies an AC voltage or DC voltage to both ends of the conductive film 1.
This is a circuit that applies voltage. If the resistance value of the conductive film 1 is defined as the current flowing through the conductive film 1 due to the application of the R1 voltage, then the conductivity?
The 1i film 1 consumes the power of 2R, and the conductive film 1 generates heat. Guide! ! Since the membrane 1 and the glass tube of the fluorescent lamp are in close contact, heat is efficiently transmitted to the glass tube, increasing the mercury vapor pressure inside.
熱陰極螢光灯の場合には、駆動回路４は、従来の蛍光灯
の予熱装置の蛍光灯放電回路６とフィラメント予熱回路
７の両者を含む回路である。In the case of a hot cathode fluorescent lamp, the drive circuit 4 is a circuit that includes both the fluorescent lamp discharge circuit 6 and the filament preheating circuit 7 of a conventional fluorescent lamp preheating device.
また、蛍光灯の陰極側と導電膜１の片端を電気的に接続

電が始まり易くなるような放電の補助用電極として兼用
できる。Furthermore, by electrically connecting one end of the conductive film 1 to the cathode side of the fluorescent lamp, the conductive film 1 can also be used as a starting electrode, that is, as an auxiliary discharge electrode that facilitates the initiation of discharge.

Since it is used for both purposes, it does not take up space, has a simple structure, and is low in cost.
