为什么我的LED灯会闪烁？原因与解决方案
定义: LED 频闪是光输出的快速反复变化，通过频闪百分比和频闪指数衡量，依据 IEEE 1789-2015。所有调光级别下频闪低于 5% 可视为无频闪。
适用标准: IEEE 1789-2015, NEMA SSL 7A-2015, IEC 60929, IEC 62386, IEC 62384:2020, IEC 61347-2-13. LED灯闪烁常见原因：调光器不兼容、驱动电源故障、电压不稳或灯泡老化

工矿灯IP65在实际使用中的陷阱——食品厂交了学费
给某食品加工厂装了60盏标称IP65的LED工矿灯。14个月后开始陆续坏。 原因分析： - IP65测试标准（IEC 60529）：6.3mm喷嘴，12.5 L/min，距离2.5-3m，测试时间每平方米1分钟 - 食品厂的实际情况：每天高温高压水冲洗（80°C，70bar压力），蒸汽弥漫 - IP65根本模拟不了这个工况 应该用什么：IP69K（DIN 4…
