6.11.1 The minimum spacings shall be not less than those shown in Table 6.11.1 between:
(a) uninsulated live parts of different potential; and
(b) uninsulated live parts and non-current-carrying metal parts.
那麽灯头两极间是要符合这个要求的, 爬电距离6.4mm, 但是: 7.3.3有讲g8卤素灯可用於高压,
然而,测得好几家的G8灯头爬电距离都不足6.4(灯头通过UL认证), 现在有点搞不懂为什麽?作者: ll123456 时间: 2012-1-25 01:42
For the lamp base, you can not reference UL1598 or UL153, you must reference the specified UL standard for the lamp base, normally, if the lamp is for general use, you can use UL1598 or UL153 to judge, but if for non-general use, you only can reference the specified test report, for example, most of outdoor use lamps have their own description in the FUS procedure.作者: xshrmm 时间: 2012-1-25 01:43

只要灯头具有UL认证一般就没有问题了。作者: sd929898 时间: 2012-1-25 01:43
建议看看灯头的UL报告.
