Unverified85% confidenceDecision RuleTime unknown
线性铝合金型材灯带槽深度需≥灯带PCB宽度+散热余量，选择带乳白PC灯罩的型材可消除颗粒感；型材还起散热作用，无型材裸贴的灯带寿命衰减快

Unverified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80% similarUnverified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79% similarUnverified面板材质优先选PC阻燃材质或钢化玻璃，避免劣质塑料在开关发热部位老化黄变；调光开关因内部有调光电路，发热高于普通开关，散热和阻燃等级更重要79% similarUnverified封闭无散热空间（铝合金深槽外再密封/暗装吊顶夹层）不建议用高功率(>10W/米)灯带，散热不良会加速LED光衰和背胶脱落；密闭安装选低功率并搭配铝槽散热78% similarUnverified散热直接决定寿命：金属（铝）散热灯体比全塑料外壳寿命长，同瓦数下塑料外壳筒灯高温衰减快、易早期光衰78% similar
