对于一个节能灯, 有疑虑的应该是灯管和灯头是否属于"用戶可接觸區域", 灯管是默认的不可接触的部分,因为在工作中会很热, 且其工艺使其不可能通过标准中的机械测试.如20 DROP TEST 中20.4 有说明了灯管破损可接受.
以上同意。。。
至于灯头, UL1993的APPENDX A中引用了UL496, UL496中有这么一部分.
7.1.1 An Edison-base lampholder, other than the surface-cleat type, shall be provided with an enclosure that prevents unintentional contact with all uninsulated live parts of the device, except the screw shell and center contact in the lamp cavity, while the lampholder is completely assembled and installed as intended.
