Phase Cut Dimming for Solid State Lighting: Basic Compatibility
Organization:
NEMA - National Electrical Manufacturers Association
Year: 2013
Abstract: This standard provides compatibility requirements when a forward phase cut dimmer is combined with one or more dimmable LED Light Engines (LLEs). A LLE, for the purposes of this document comprises one or more LED modules, LED control gear (integral or remote), and a connection to the mains circuit1.
The requirements in this standard do not limit its use to any specific lighting product type or application and is suitable for use globally. For the purposes of this standard, compatibility means:
• The reliability of the dimmer and LLE are not affected by combining them.
• Dimming behavior meets or exceeds the behavior specified in sections 3 and 4.
Any interfaces between control gear and LED module(s) within the LLE are undefined in this standard. Such an interface may take a variety of forms. For example, it may be a constant voltage interface, a constant current interface, or a low-voltage AC interface produced by control gear that is simply a stepdown electronic transformer. In all cases, compatibility is only defined for the LLE (which may contain one or more specific combinations of control gear and LED module(s)), and not for either component independently. To be considered compliant with this standard, the control gear and modules shall be operated together. This standard does not preclude future standards that will permit separate qualification of control gear and module components, with interfaces defined between them that ensure a proper SSL 7A LLE interface from the point of view of this standard.
This standard is forward-looking and is intended to be used to design and qualify dimmer and LLE products (including integral or remote control gear) for use with each other. It is not intended for use to determine compatibility with existing products or the installed base of LLEs and phase cut dimmers. For information on compatibility with the installed base of dimmers, see SSL 6-2010.
Note: The requirement for compliance to this standard does not supersede applicable international or local regulation.
