灯具耐压问题

在LED灯具的设计中加入了防雷二极管，但是做电气强度试验到一定电压时就会超漏。厂家解释说灯具的防雷等级还高于耐压1500V。请问下各位，这个原理是什么！

非常关注这个问题，希望有高手给解释

You can
1. Check the surger protector's datasheet to check whether the dielectric performance is higher than the whole product's requirement, if not, I think it's the surge protector's issue;
2. Check if there are some capacitors with low voltage rating, if there are, disassemble them or change the test voltage from AC to DC;
3. Adjust the leakage current setting to higher level, but still within the standard's requirement;
4. If all above proves that there is still a problem when doing this test, then verify the products step by step, try to find out which section or which components can not fulfill the test's requirement, then solve it...

多谢 多谢基本上找到原因了！

I see!
不过很多人英语不行，最好有中文注解！

最好用中文注解，看E文很伤神

maybe you are right, but there are so many standards related with safety are english version,....
