ul 燈具爬電距離問題
6.11 Electrical spacings6.11.1 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.
那麼燈頭兩极間是要符合這個要求的, 爬電距離6.4mm, 但是: 7.3.3有講g8鹵素燈可用於高壓,
然而,測得好幾家的G8燈頭爬電距離都不足6.4(燈頭通過UL認証), 現在有點搞不懂為什麼? 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. 但是ul1598里同沒有講到燈頭不用符合 6.11的要求啊 学习了! 只要灯头具有UL认证一般就没有问题了。 建议看看灯头的UL报告. 燈頭只是零部件,不是做個認證就可以到處用的,同樣是要符合成品標準的要求吧
