论荧光灯频闪效应及其电子镇流器的设计误区

The Frequency-Flicker Effection of Fluorescent Lamps and Designing Objection of Electronic Ballast

荧光灯 (含CFL节能灯 )均存在不同程度的频闪 ,客观上长期危害人的健康和损害人的视觉系统 ,而解决和降低办公场地、工厂企业、教学科研、生活居住等环境大面积照明时荧光灯频闪效应的有效和重要的途径之一是采用符合电磁兼容 (EMC)标准要求的电子镇流器 ,并同时大幅提高电子镇流器的工作频率 (≥ 4 0KHz)。

The frequency flicker exists more or less when Fluorescent Lamps(including Compact Fluorescent Lamps) are in service.No doubt it will be harmful to the beath of people,especially to the vision system.One of the effective and important solutions to reducing the frequency\|flicker effec of fluorescent lamps at large area lighting is to use the electronic ballast which meet the EMC standards,and to raise greatly the operative frequency of electronic ballast(>40KHz).
