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,
s/ _/ H" ]: f g6.2.3 A wire is considered to be mechanically secure when one or more of the following is provided:: t5 ~1 }; H5 K% r x9 {+ M4 h
a) At least one full wrap around a terminal, m( A0 R3 {0 [+ F% R* G2 l
b) At least one right angle bend when passed through an eyelet or opening, except on printedwiring

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, |
