12、Electrical Manufacturers Association AMERICAN NATIONAL STANDARD Approval of an American National Standard requires verification by ANSI. ANSI states that the requirements for due process, consensus, and other criteria for approval have been met by the standards developer. Consensus is established wh
13、en, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected interests. Substantial agreement means significantly more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be c
14、onsidered, and a concerted effort be made toward their resolution. The use of American National Standards is completely voluntary; their existence does not in any respect preclude anyone, whether they have approved the standards or not, from: manufacturing, marketing, purchasing, or using products,
15、processes, or procedures not conforming to the standards. The American National Standards Institute does not develop standards, and will under no circumstances give an interpretation of any American National Standard. Moreover, no person shall have the right or authority to issue an interpretation o
16、f an American National Standard in the name of the American National Standards Institute. Requests for interpretations should be addressed to the secretariat or sponsor whose name appears on the title page of this standard. Caution Notice: This American National Standard may be revised or withdrawn
17、at any time. The procedures of the American National Standards Institute require that action be taken periodically to reaffirm, revise, or withdraw this standard. Purchasers of American National Standards may receive current information on all standards by calling or writing the American National St
18、andards Institute.

21、cument apply or are directly related to lighting systems and are used in multiple 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 ANSI C137 lighting system standards. Where this doc
22、ument does not include a term, other references are listed. 2 Terms and Definitions CoexistenceThe ability of systems or system components to operate in the same environment without having harmful or undesirable effects on each other. CompatibilityThe ability of a system or system components to have
23、 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 not recommended when other terms are more specific. See definitions of coexistence, intero
24、perability, and interchangeability to determine which are most appropriate. Emergency Lighting Charging PowerPower used to charge batteries or other energy storage devices that are used as power sources for emergency lighting. Functional InterchangeabilityThe ability of a system component to perform
25、 in an equivalent manner as another system component. Note: The system component may not be physically interchangeable. InterchangeabilityThe ability of a system component to replace the form and fit of another system component and perform in an equivalent way. Note: See definitions of functional in
26、terchangeability and physical interchangeability. InteroperabilityThe ability of systems or system components to transmit, receive, interpret, and/or react to data and/or power and function in a defined manner. Lighting Input PowerThat part of the system input power consumed in the production of pri
27、mary (on-state) light output. Lighting SystemA 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:
28、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
29、, system operation and maintenance, and daylight integration are considerations that can be addressed in whole or in part by a lighting system. Physical InterchangeabilityThe ability of a system component to replace the form and fit of another system component. Note: The system component may not per
30、form in an equivalent way. ANSI C137.0-2017 Page 2 2017 National Electrical Manufacturers Association Secondary Device PowerPart 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
31、that draw secondary device power include home and building electronic 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; daylig
32、hting fenestration (e.g., blinds) control; sensors; and portions of embedded power supplies that do not contribute to light output. Standby Mode of a Driver/BallastMode of operation of an LED driver or a discharge lamp ballast during which it is connected to the mains power, it provides no output po
33、wer to the light source, and its control circuitry remains responsive to a control signal. Note: Standby mode may also be called “Electronic Off.” Standby PowerElectrical power consumed by the lighting system under normal operating conditions, with the light source(s) switched off via a control sign
34、al, excluding any emergency lighting charging power and secondary device power. System Input PowerTotal electrical power consumed by the system, including the operation of all electrical components necessary for its intended functioning. 3 Informative References This standard should be used in conju
