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…
DLC认证值不值得多花钱？一篇文章算清楚
DLC（DesignLights Consortium）V5.1标准下的两个等级对比： DLC Standard（标准版）： - 最低光效：100-120 lm/W（因品类不同） - L70寿命：≥50,000小时 - 显色指数：≥80 - 功率因数：≥0.90 - 谐波失真THD：≤20% DLC Premium（高级版）： - 更高光效：120-145+…
出口欧盟的LED灯需要哪些认证？别漏了REACH和WEEE
LED灯具出口欧盟，至少涉及以下法规： 1. LVD低电压指令（2014/35/EU）→ EN 60598-1 安全测试（必做） 2. EMC电磁兼容（2014/30/EU）→ EN 55015 发射 + EN 61547 抗扰度（必做） 3. RoHS有害物质限制（2011/65/EU）→ 10种物质限制（必做，测试标准EN 62321） 4. ErP能效…
