摘要
掌握荧光灯光电参数之间的变化关系，对深入了解荧光灯的工作特性，准确地测量荧光灯的总光通量及其电参数，对生产、质检和计量测试都是很有意义的。本文叙述了在不同输入电压下，测量灯管的总光通量、灯管功率、工作电流、灯端电压的实验。计算出各自以输入电压为２２０Ｖ时对应的值作参考的变化率。再以总光通量的变化率除以对应的电参数的变化率。本文还叙述了分别控制输入电压为２２０Ｖ和灯管功率为４０Ｗ时，改变电源频率从４６Ｈｚ到５６Ｈｚ，测量荧光灯的总光通量及其电参数、考察其光电参数随频率变化的规律。
It is very interesting to know well variations of different photoelectrical parameters of the fluorescent lamp for understanding deeply the work characteristics of fluorescent lamp, measurement accurately of total luminous flux and its photoelectrical parameter.In This paper are describe the variations of the total luminous flux, lamp wattage, woring current and voltage across the lamp with different input voltage.The variation rates of different photoelectrical parameters of various imput voltage have been calculated.The paper discusses also in controlling the input voltage 220V and the lamp wattage 40W, the change of supply frequency from 46Hi to 56Hi,the measure ment of the total luminous flux and electrical parameters of the fluorescent lamp,and the investigation of variation of its photoelectrical parameters with supply frequency.
