ANSI NEMA C137.0-2017 pdf free download – Lighting Systems — Lighting Systems Terms and Definitions.
The definitions listed in this document apply or are directly related to lighting systems and are used inmultiple lighting system standards.This standard is intended for use by lighting systems standards
developers. The terms found in this document are recommended for use in all ANSl C137 lighting systemstandards. Where this document does not include a term, other references are listed.
2Terms and Definitions
Coexistence-The ability of systems or system components to operate in the same environment withouthaving harmful or undesirable effects on each other.
Compatibility—The ability of a system or system components to have coexistence, interoperability,and/or interchangeability with other systems or system components, depending on the context.
Note:Because the terms “compatible” and “compatibility” are ambiguous, their use is notrecommended when other terms are more specific.See definitions of coexistence,
interoperability, and interchangeability to determine which are most appropriate.
Emergency Lighting Charging Power—Power used to charge batteries or other energy storage devicesthat are used as power sources for emergency lighting.
Functional Interchangeability—The ability of a system component to perform in an equivalent manneras another system component.
Note: The system component may not be physically interchangeable.
Interchangeability—The ability of a system component to replace the form and fit of another systemcomponent and perform in an equivalent way.
Note: See definitions of functional interchangeability and physical interchangeability.
Interoperability—The ability of systems or system components to transmit, receive, interpret, andorreact to data and/or power and function in a defined manner.
Lighting Input Power—That part of the system input power consumed in the production of primary (on-state) light output.
Lighting System—A collection of functionally related components that can include, but is not limited to,luminaires, sensors, controllers, software, firmware, windows, or skylights, including their accessories,installed in an application to provide illumination.
Notes:
1. Lighting systems may be networked to provide central or remote control and monitoring
functions.
2. Lighting systems may be connected to or integrated with other systems or devices.3. Energy use, light quality, light level, human comfort, visibility, safety and security, the
physical environment,system operation and maintenance, and daylight integration areconsiderations that can be addressed in whole or in part by a lighting system.
Physical lnterchangeability—The ability of a system component to replace the form and fit of anothersystem component.
Note: The system component may not perform in an equivalent way.
Secondary Device Power—Part of the system input power not being used to produce primary (on-state)light, excluding any emergency lighting charging power and standby power.
Note: Examples of devices that draw secondary device power include home and buildingelectronic systems (HBES) and building automation and control systems(BACS) controllers;communication devices not dedicated to lighting functionality, such as Wi-Fi routers; heating,ventilation, and air conditioning (HVAC) control; daylighting fenestration (e.g., blinds) control;sensors; and portions of embedded power supplies that do not contribute to light output.
Standby Mode of a Driver/Ballast—Mode of operation of an LED driver or a discharge lamp ballastduring which it is connected to the mains power, it provides no output power to the light source, and itscontrol circuitry remains responsive to a control signal.
Note: Standby mode may also be called “Electronic Off.”
Standby Power—Electrical power consumed by the lighting system under normal operating conditions,with the light source(s) switched off via a control signal, excluding any emergency lighting charging powerand secondary device power.
System Input Power—Total electrical power consumed by the system, including the operation of allelectrical components necessary for its intended functioning.
