频闪指标看'频闪深度＜3.2%（豁免级）'或选带DC恒流驱动的产品，避免购买标注PWM调光但未说明频率的低价灯，频闪是隐性视疲劳主因

UnverifiedPWM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84% similarUnverified无频闪要看'无危害频闪'认证（波动深度符合IEEE PAR1789标准），普通LED驱动在低亮度调光时频闪反而加剧，PWM调光台灯低档位易频闪，DC恒流调光更安全84% similarUnverified触摸调光和无极调光看似高级，但PWM调光（脉宽调制）在低亮度档位可能产生频闪，若产品未说明采用DC恒流调光，避免长期使用最低亮度档84% similarUnverified健康向应用应确认灯带通过无频闪认证（波动深度＜3125Hz以上或直流恒流驱动），廉价PWM调光灯带在低亮度时频闪严重，长时间使用易引起视疲劳83% similarUnverified低蓝光与无频闪需看驱动方案：恒流驱动+DC供电才可能做到低频闪，PWM低频调光在低亮度时频闪严重，健康场景应确认标注无可视频闪或频闪深度<3.2%83% similar
