从以下三个定义来看，LED灯管或灯泡内的应属于integral lamp controlgear（整体式）的。它是构成整个灯的不可拆卸部件，不能从灯上拆下来单独测试，它的防触电必须依靠灯的外壳。; s/ d) g' }+ \8 D" h0 M9 x
- ~# F: z7 M& Q, ^% O% Z( A% }. q是独立式还是内装式呢？除了要从结构判断之外还要看客人的设计定位（ designed to be）。内装式电源也有自已的防触电保护外壳，并不是独立式才能有。最终能否做独立式要从产品的结构上判定了。比方说一个LED电源，它的输入和输出是通过接线端子台（terminal block)则结构上要求判定为内装式（它本身也有外壳但是防触电保护不足够，输入端子台还要依靠灯具的外来保护）。如果一个电源它的输入是通过电源线来连接的且能达到EN60598-1的电源线拉力测试则可以判定为独立式。' K8 K1 |7 y4 V J* E" a
