Unverified75% confidenceDecision RuleTime unknown
调光方式优先选无极调光而非分档调光，可精确匹配用餐/聊天/收拾等不同亮度需求；PWM调光频率过低（＜1000Hz）会导致低亮度时频闪，长时间就餐易眼疲劳

Unverified亮度调节优先选PWM高频调光（≥2000Hz）而非降压调光，低频PWM在低亮度时肉眼可见频闪，长时间伏案会加重视疲劳89% similarUnverified低亮度下的调光平顺度和无频闪同样关键：便宜的PWM调光灯在1%~10%低亮区间会闪烁或跳档，拍高速快门/慢动作会出现横纹，需选支持高频无频闪调光的灯87% similarUnverified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86% similarUnverifiedPWM调光的LED氛围灯在低亮度档可能有频闪，对拍摄美食视频/照片会产生条纹，长时间就餐也易视觉疲劳，选择标注无频闪或DC调光的型号86% similarUnverified调光平滑度与低亮度闪烁存在矛盾，廉价PWM调光灯泡在10%以下低亮度时频闪严重，长期使用易视疲劳；用于卧室夜灯应选支持低亮度无频闪或高频PWM（>3000Hz）的产品86% similar
