IEC 62386-104:2019+AMD:2023 specifies a bus system for control by digital signals of electronic lighting equipment. This part of IEC 62386 applies to 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 62386-101.
Where the electronic lighting equipment is covered by the scope of IEC 61347 (all parts), it is in line with the requirements of IEC 61347 (all parts), with the addition of DC supplies.
