低蓝光/无频闪需认准两点：调光方式为高频PWM（≥3000Hz）或DC直流调光，且有IEEE 1789无频闪或护眼认证，普通低频PWM灯带在低亮度下频闪严重，长时间处于其光下易视疲劳

Unverified追求健康护眼应选支持PWM频率≥3125Hz或DC恒流调光的灯带，并有无频闪/低蓝光认证（如莱茵TÜV Low Blue Light、IEEE 1789无频闪）；低价灯带常用低频PWM调光，调暗时频闪加剧91% similarUnverified护眼看类DC调光或高频PWM调光（≥1920Hz），单纯的'低蓝光认证'（如莱茵TÜV）不解决频闪问题；对频闪敏感人群优先查PWM调光频率而非蓝光认证标签90% similarUnverifiedPWM调光频率过低会产生频闪，防蓝光灯带若采用低频PWM调光反而伤眼，选购调光款需确认调光频率≥3000Hz或采用DC恒流无频闪调光89% similarUnverified调光方式优先选无频闪（DC调光或高频PWM＞3000Hz），低频PWM在低亮度下频闪严重，长时间近距离使用易致眼疲劳87% similarUnverified调光方式优先选DC直流恒流调光或高频PWM（＞3125Hz），低频PWM调光（尤其调暗时）会产生肉眼难察觉的频闪，是低价灯的隐藏坑87% similar
