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,$ ]* J3 ^) G; ^$ r( ^8 O3 ]7 w& F
6.2.3 A wire is considered to be mechanically secure when one or more of the following is provided:: o: `$ \# Q+ s
a) At least one full wrap around a terminal,
. r' v# h) a' K! K" u3 A( Jb) At least one right angle bend when passed through an eyelet or opening, except on printedwiring
; N3 O7 C1 j. X+ W% g. hboards where components are properly inserted and soldered or mechanically secured: ^9 f& t9 Z7 Y2 A0 t1 v0 u& P; i- y
by design, or
+ E8 \& b* |- v. [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, |
