多谢各位的回复, 那基本上输入线是要满足18AWG, 我现在LED 驱动的部分PWB上是没有变压器的,所以我可能描述的非隔离是错误, 所以应该输出线也要按照高压来评估,满足18AWG, 另外目前我们的灯具针对lamp base 的触点是直接焊上两条电线,标准要求:6.2.2 A soldered joint shall be mechanically secure before soldering 需要机械固定,
4 F7 ^$ Q8 J$ a. o0 i6.2.3 A wire is considered to be mechanically secure when one or more of the following is provided:" Q( C8 N, O7 b* O% Z

c) It is twisted with other conductors.所以我要确定是不是机械固定必须按照6.2.3的a,b,c, |
