| 摘要: |
| 对间歇振荡器的有功功率输出特性和频率输出特性研究发现:在一定范围内,改变电源的输出功率,间歇振荡器的有功功率的输出,可大致保持不变;在光管正常发光的范围内,它的振荡频率位于中低频之间。用电位器代替固定电阻,使灯的效率提高30%以上。用一段中波磁棒,作为脉冲变压器的磁芯,使灯的制作大为简化。对三极管额定功率的合理选择,使设计制作的应急灯达到预想目的。 |

| Abstract: |
| The efficient power output of interval oscillator can be held almost constant when the output power of the voltage source is varied in a given range, and its oscillatory frequency lies in the range between low and medium frequency when the tube is in its regular lighting scope. Replacing the fixed resistor with a variable resistance can raise the efficiency of the lamp 30% more than the reqular one. Taking a ferromagnetic bar of medium wave as the core of the pulse voltage transformer can greatly simplify the making of the lamp. With reasonable choose of the limited power of the transistor, the lamp can be up to an ideal property. |
