The IEC 62386 series specifies a bus system for control by digital signals of electronic lighting equipment. This IEC 62386 part allows a system with wireless or alternative wired communication between its units, instead of a wired bus system, where the meaning of wireless or alternative wired communication , or in short telecommunication , is any type of communication network different from the wired system described in IEC 62386-256 101amd1:20xx. Where this electronic lighting equipment is covered by the scope of IEC 61347, it should be in line with the requirements of IEC 61347, with the addition of DC supplies.
