control cable is classified as ELV potential and so requires only basic insulation from AC mains; it can be run next to those mains or within a multi-core cable that includes mains power.
address this issue, the international Zhaga Consortium has established industry specifications of interfaces for components used in LED luminaires. The consortium is a member program of the IEEE Industry Standards and Technology Organization and has more than 120 members as of 2019. Now’s a good time to make clear the difference between a light fixture and a luminaire. The term “luminaire” is used by the Illuminating Engineering Society (IES) Lighting Handbook, ANSI/ NEMA standards, and the IEC. It was added to the National
Electrical Code (NEC) handbook in 2002, with a formal definition as “a complete lighting unit consisting of a lamp or lamps together with the parts designed to distribute the light, to position and protect the lamps, and to connect the lamps to the power supply.” A luminaire includes the lamp and all components directly associated with the distribution, positioning, and protection of the light unit, and specifically does not include support components, such as an arm, tendon, or pole; the fasteners used to secure the luminaire; control or security devices; or power supply conductors.
Beyond DALI-2: Zhaga specification targets luminaires
Standards such as DALI-2 are important but can only go so far. It is not within their purview to define how the standard is to be linked to specific applications, such as LED lighting and luminaires. To
