前言我厂生产的100W高功率荧光灯是在保持与普通40W荧光灯相同玻管尺寸的前提下,通过增加输入电功率来提高光通量(指标是:燃点100小时后的光通φ≥4000流明)。随着工作电流和功率的增加,灯管的光输出将会接近饱和,为了维持光效不下降,该灯管是通过充填扩散系数较大的氖气,以增加电子温度的办法来实现的。因为,加入少量氩气可以降低阴极位降,改善启动特性,所以,在实际生产 Preface The 100W high power fluorescent lamp manufactured by our factory is designed to increase the luminous flux by increasing the input electric power under the premise of maintaining the same glass tube size as the ordinary 40W fluorescent lamp (the index is: luminous flux φ≥4000 lumens after 100 hours of ignition). With the increase of operating current and power, the light output of the lamp will be nearly saturated. In order to maintain the luminous efficacy, the lamp is realized by filling the neon with larger diffusion coefficient to increase the electron temperature. Because, adding a small amount of argon can reduce the cathode drop, improve the startup characteristics, so in the actual production
