该文对日光灯电子镇流器中传统的频率控制调光方法和新近取得专利的电压控制调光方法,进行了比较和评定。在宽的调光范围内,记录并对比了基于这两种调光方法的2×36 W电子镇流器的功率因数、能量效率、电子损耗、单位功率光通量(lm/W)以及峰值系数。结果发现,通过灯的调光对比在很多方面,电压调光控制法比频率控制法好得多,尤其电压调光法比频控方法,具有更高的能量效率和更多的单位功率光通量,电压控制调光的显著特点是随着灯功率的减小,其电子损耗也减小。
This paper compares and evaluates the traditional frequency-controlled dimming method in the fluorescent electronic ballast and the newly patented voltage-controlled dimming method. The power factor, energy efficiency, electron loss, unit power flux (lm / W), and crest factor of 2 × 36 W electronic ballasts based on these two dimming methods were recorded and compared over a wide dimming range. The results show that, compared with the dimming control of light in many ways, the voltage dimming control method is much better than the frequency control method, especially the voltage dimming method than the frequency control method, with higher energy efficiency and more unit power flux, The distinguishing feature of voltage-controlled dimming is that as the lamp power decreases, its electrical loss also decreases.
