This part of IEC 61347 specifies general safety requirements for controlgear for electric light sources for use on DC supplies up to 1 500 V or AC supplies up to 1 000 V at 50 Hz or 60 Hz.

NOTE 1 In the remainder of this document "light source" is used instead of "electric light source".

This document is only applicable in conjunction with the relevant part(s) of the IEC 61347-2 series.

NOTE 2 As far as covered in the scope of the relevant part of the IEC 61347-2 series, this document is also applicable to controlgear used for electric sources producing optical radiation with the same technology used for purposes different than illumination and producing radiation other than visible spectrum.
