真正无频闪需认准DC调光而非高频PWM调光，PWM调光频率≥3840Hz才能基本消除频闪对眼睛的影响，低于此值长时间使用易疲劳

UnverifiedPWM调光频率≥1920Hz或采用类DC调光才算真正护眼，低于360Hz的低频PWM长时间使用易导致眼疲劳；对频闪敏感人群应认准全程DC调光或高频PWM≥2160Hz机型92% 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91% similarUnverified亮度调节需支持无级/PWM高频调光（≥3000Hz以上或DC调光），低频PWM调光在低亮度下频闪明显，长期夜间使用易造成眼疲劳和头痛91% similarUnverified真正护眼需高频PWM调光（≥1920Hz）或原生DC调光，1920Hz以下的PWM调光在低亮度时频闪明显，敏感人群仍会眼疲劳91% similarUnverified调光方式优先选PWM频率>3000Hz或DC直流调光的产品，低频PWM（<1250Hz）在低亮度时频闪严重，长期使用引起眼疲劳91% similar
