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 {) N5 c- d! y- G, g* v9 H( S" z" M( Z
6.2.3 A wire is considered to be mechanically secure when one or more of the following is provided:
' z9 [4 ]$ I5 B: Na) At least one full wrap around a terminal,2 j" k2 W( n, a
b) At least one right angle bend when passed through an eyelet or opening, except on printedwiring+ ?2 l/ e9 w: P0 |. s
boards where components are properly inserted and soldered or mechanically secured

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, |
