如果你家里有示波器,看看家在灯上电压,用交流挡,最小10毫伏,
我比较过很多加市场灯,其电压波动从40毫伏到120毫伏不等,这些都能造成闪烁;
我们的专利没有电压波动,没有波动;
我建议你用示波器测量一下;

用同样方法测量灯闪烁,

In either case (bright or low light), it has been assumed that, because the flicker is largely imperceptible, it is acceptable. However, studies have linked flicker to health problems. So, even though flicker at these frequencies may not be visible to the naked eye, there is evidence that the human brain can detect light flicker frequencies as high as 200Hz. Potential problems include headaches, eye strain, impaired visual performance or, in extreme cases, epileptic seizure.
IEEE等很多机构研究,表明闪烁光对人体危害;

这篇文章最后的附表列出所有闪烁光对视力的危害,
IEEE有一个研究小组PAR1789做了大量的研究,高频光造成视力下降头疼

澳大利亚大学发现低频光的危害
中国南通大学附属医学院发现低频光对于老鼠造成近视。老鼠从早上8点到晚上8点用2赫兹闪烁光(一个周期内50%时间亮,50%时间暗),照了六个星期,近视程度比对比组大大加深。[1]
澳大利亚La Trobe大学用小鸡做实验发现低频光促进了近视。[2]
俄亥俄大学眼科学院认为高度近视的人,视网膜脱离,脉络膜萎缩,白内障和青光眼的风险更大。[3]
杜克大学眼科医学中心发现严重高度近视和视网膜脱离,黄斑脉络膜变性,早生白内障,青光眼和其相关的眼部并发症是致盲的主要原因。[4]
红外线对眼睛影响的研究
瑞典乌普萨拉大学医院神经眼科做了研究。一些科学的数据表明,近红外辐射可能会导致在晶状体的累积损伤[5].
德州大学奥斯汀分校的生物医学工程部门做了试验,发现1300 nm红外线对家兔视网膜造成损伤。[6].
