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。

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。
