根据IEC 60598-1：2003.查得定义为：
Semi-luminaire:
Unit similar to self-ballasted lamp but designed to utilize a replaceable light source and /or starting device.
Note1: The Lighht source component and/or starting device of a semi luminaire is readily replaceable.
Note2: The ballast component is not replaceable and is not disposed of each time a light source is replaced.
Note3: A lampholder is required for supply connection.
Note4: For examples and further infomation, See IEC 60972

一句话，半灯具就是光源可更换或启动装置可更换的自镇流灯。这种产品极少见，一般都做成自镇流灯了，也就是说光源不可更换。
