Unverified灯珠密度与发热/寿命存在权衡：高密度高亮度灯带发热更大，若安装在铝合金散热槽内寿命更长，长时间高亮使用建议搭配铝槽散热而非直接贴纸粘贴83% similarUnverified流明越高散热要求越高，高流明手电为控温会激进降档，选带铜基板或大金属灯头的型号持续输出更稳定；小巧的AAA电池手电通常无法稳定输出500流明以上83% similarUnverified灯珠密度高照度强但发热大、需散热片或风扇，密集LED灯板长期无散热会缩短寿命并可能烤伤近距离叶片，功率＞50W建议选带铝基板散热的83% similarUnverifiedLED车灯散热方式决定寿命：带铝制散热片的被动散热比涡轮风扇散热更耐用，风扇是易损件且进灰易坏；封闭大灯内建议选带编织铜带散热或大面积铝鳍的产品83% similarUnverified扩展坞接口越多、供电越强则发热越大，全金属外壳（铝合金）虽本身发热感更明显但散热更好，塑料壳摸着凉实际内部积热更严重更易降速82% similar
