什么是 LM-70
LM-70 也被称为照明工程学会标准 LM-80-08,是照明行业的行话,指的是一种测量的标准化方法。 流明維持率 的 LED 光源.流明维持率是衡量光源在新光源时的光输出与其在未来某一特定时间的光输出的比较。就 LM-70 而言,它专门评估 LED 的使用寿命。 燈具 在光输出减弱到 70% 初始水平之前的预期运行小时数。
从 Rayzeek 运动传感器产品组合中获得灵感。

LM-70 标准由照明行业公认的权威机构北美照明工程学会 (IESNA) 制定。该标准考虑到了可能影响 LED 寿命的各种因素,如工作温度、驱动电流以及 LED 灯具制造所使用的技术和材料。
通过提供测量流明维持率的标准化方法,LM-70 允许制造商和用户评估 LED 光源的预期寿命。通过它可以对不同的 LED 产品进行比较,有助于对其寿命和性能做出明智的决定。需要注意的是,LM-70 并不能准确预测 LED 的使用寿命,因为实际使用寿命会因具体条件和使用情况而异。不过,LM-70 是估算 LED 灯具使用寿命并确保其符合所需性能标准的重要工具。
