摘要
文章介绍了光源产生频闪的原因和传统光源的频闪特性,引入波动深度、闪烁指数的概念分析了传统光源的频闪效应并进行量化。列举了光源频闪在功能性照明场合对人体的生理影响和危害。在进行测量、研究的基础上详细分析了固态照明LED的频闪现状,给出了几种频闪小或基本无频闪的LED光源工作情况。
This article introduces the essence of light flicker and flicker characteristics of traditional lights. Analyzes the flicker effect on traditional light by introducing fluctuation depth and flicker index and make it quantified. Some examples are given in this article to show the physiological effects and hazards of flickers on human body under the circumstance of functional lighting. Comprehensive research is done in details to analyze the current status of light flicker on LED lighting. Some working status of LED lighting which had limited light-flicker or non-light flicker are also be described in this article.
