1:有决议称III类LED 灯具温升测试电压是1.1倍,如果一款灯具带适配器,输出安全特地电压,那么这个灯具应该算是II 类还是III 类?) z- b' U- j1 i
2:耐压测试时样品发出的声音算是正常现象吗?所谓的闪络是指出现电火花吗 ?% g6 @$ Y2 K# R, y/ D! u
3:电容放电测试,标准说的是1分钟,1秒钟,那么1分钟或1秒钟后的放电电压超限该怎么判定?7 _: e2 r: O9 b) x. |6 ]
4:嵌入式灯具,IEC60598-1:2014 附录D中描述隔热棉是包裹在测试箱子外面的,我这里有黄颜色的那个隔热棉,不知道是否符合要求,请问大家的隔热棉是这个样的吗 ?
