正常的LED自整流灯好像基本都用24AWG的电子线,& A+ s0 h8 t/ i C
UL8750中有提到可以用小于24AWG电子线的情况,7 s8 k( H A7 I7 z! Q$ r7 j
7.3.7 Conductors of a size smaller than 24 AWG (0.21 mm2) are permitted when the conductors are in

non-isolated LVLE circuits, such as by a barrier or reliably fixed spacing of minimum 6.4 mm (0.25 in).
" {6 ], e5 l- X至于Conductor是不是用在Class 2或LVLE电路,是不是需要UL在对LED自整流灯做认证时进行单独的什么测试进行评估?还是需要对LED Driver单独做UL1310认证呢?
% Q$ o& L! W* [2 u4 s6 ^% W' J这个我就不清楚了,期待高手解答。 |
