Unverified选择DC调光（直流恒流）而非PWM低频调光的夜灯，低频PWM调光在低亮度下频闪明显，长期对婴儿视觉发育不利，认准标注'无频闪'或'DC调光'88% similarUnverified无频闪认证只是标注PWM调光的灯在低亮度档往往频闪更严重，儿童房和长时间用眼场景不建议买低亮度靠PWM调光的产品，应选DC调光或混合调光87% similarUnverified无极调光通常采用PWM或DC调光，低频PWM在手机镜头下可能产生频闪水波纹，选择标注‘无频闪/高频调光’的产品可避免视频录制出现闪烁条纹86% 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85% similarUnverified关注调光时的PWM频率或选择DC无频闪机型，低频PWM调光在低亮度下频闪严重，长时间用眼环境（书房儿童房）应选无可见频闪认证机型85% similar
