。A conventional example is shown in FIG. In other words, when switching to switch ll-contact a as shown in Figure (a), the fluorescent lamp 2
Then, the main lighting circuit of the ballast 3 is closed and the gummy lamp 4 is turned on. When the changeover switch 1 is switched to the contact position as shown in FIG. 2B, a sub-lighting circuit for the miniature bulb 5 is formed and the miniature bulb 5 is lit. When the selector switch 1 is switched to the contact C as shown in FIG. 8(C), both the conical lights are opened and all the lights are turned off.
ところが、この回路は、夜間の少ない照度が必要な照明

グ２よりも寿命が短く、輸送等の振動衝撃に弱く、また
豆球ソケットが必要であり回路電線接続を複雑にしてい
るという欠点があった。However, this circuit conveniently uses a miniature bulb 5 for lighting that requires low illuminance at night, and this miniature bulb 5 has a shorter lifespan than the fluorescent lamp 2, is susceptible to vibration and shock during transportation, etc. It had the disadvantage that it required a small bulb socket and complicated the circuit wire connection.
したがって、この発明の目的は、豆球を使用しないで簡
単に低照度照明ができる蛍光灯点灯回路ｔ−提供するこ
とである。Therefore, an object of the present invention is to provide a fluorescent lamp lighting circuit that can easily provide low-intensity illumination without using a miniature bulb.

もに開路する消灯状態となる。The preheating filamen 6) 6a and 611C are connected and a preheating current flows through the commercial ridge #E to the filaments 5a and 5b, preheating them, and the energy of the main chain 7 that causes the glow rung 8 to operate is applied to the land 6. The fluorescent lamp 6 lights up. Figure (b) shows the case of low-intensity lighting, and when the changeover switch 9 is switched to the contact point, the filament 6a #6b
, the auxiliary lighting circuit including the main chieley 7 and the auxiliary current limiting element 1O is closed, current flows through the filaments 6a and 6b, the filaments 6M and 6b emit light, and a light bulb is produced at the tube end of the fluorescent lamp 6. Corresponding illumination is obtained. The same figure (C) shows the case where the changeover switch 9t and the contact CK are connected, and both the circuits are in an extinguished state in which the circuits are opened.

器の温度上昇を保証することができる。In addition, the results of the electrical characteristics test for filament lighting are as follows: When the fluorescent lamp 6 is a straight tube of 20W and the cheap x-ray lamp is for 20W, the input power is 15W, the input current is 400mA, and the output power is ? , 8 W, and output current was 400 mA. Another lamp filament 6! The current control of l I 6b is carried out by the sub-current limiting element 10 and the main circuit 7, and by adjusting the former and suppressing the current, the lamp life can be ensured and the temperature rise of the ballast can be guaranteed. .

向上できるという効果がある。The circuit of the present invention can be applied to a lighting circuit for a fluorescent lamp having a preheated filament, and as described above, the circuit for lighting a fluorescent lamp of the present invention can be applied to a lighting circuit for a fluorescent lamp having a preheated filament. Since the lamp uses low-m degree lighting instead of a miniature bulb, the structure and wiring are simplified, the number of parts can be reduced, and the lifespan is longer than that of a miniature bulb.
