Lighting system and related equipment - Terms and
definitions
1 Scope
This Standard defines the terms and definitions of lighting, lighting systems, lighting system-related characteristics, lighting components and related equipment.
This Standard applies to related fields such as the design, production, installation, use and evaluation of lighting systems and related equipment. 2 Terms of lighting
2.1
Lighting
The application of light in scenario, object, or surrounding environment. Note: Rewrite IEC 60050-845:1987, definition 845-09-01.
2.2
Intelligent lighting
Adaptive lighting
The lighting that automatically adjusts to provide the required quality according to the environment or predefined conditions.
Note 1: Requirements can focus on different aspects, such as energy
performance, dynamic user needs, visual operation needs and
environmental atmosphere.
Note 2: The term "smart lighting" is sometimes used to express a similar meaning.
2.3
Human centric lighting
Note 3: The light source and related equipment constituting the lighting system can be an integrated unit, such as LED module, lamp or lantern.
Note 4: The lighting system can be connected to the network to provide central or remote control and monitoring functions.
Note 5: The lighting system can be connected to other systems or products, or integrated into other systems.
3.3
Intelligent lighting system
Adaptive lighting system
A lighting system that is used to provide adaptive lighting.
3.4
Human centric lighting system
A lighting system that is used to provide human centric lighting.
4 Terms related to the characteristics of the lighting
system
4.1
Energy performance (of a lighting system)
For a specific space or internal/external environment, the measured or
calculated value of energy that is consumed to meet lighting needs.
4.2
Lighting quality
A measurement that is used to characterize the overall characteristics of lighting characteristics in line with user needs and other application requirements. 4.3
Compatibility
According to the environment, the ability to coexist, interoperate and/or interchange with other systems or system components.
Note: Because the meaning of the terms "compatible" and "compatibility" is not clear, when there are other more specific terms, "compatible" and
"compatibility?€? should not be used; it is recommended to select the most appropriate term from "coexistence", "interoperability?€? and
"interchangeability".
4.4
Coexistence
The ability of a system or system components to operate together without causing harmful or undesirable effects on each other.
4.5
Interoperability
The ability of a system or system component to send, receive, and interpret data in a specific way, or the ability to respond to data or energy in a specific way.
4.6
Interchangeability
The ability of system components to be functionally and/or physically
replaceable.
Note: Interchangeability includes functional interchangeability and physical interchangeability.
4.7
Functional interchangeability
The ability of components outside the system to functionally replace the corresponding components in the system and make the system operate
equivalently.
Note: Components with functional interchangeability may not have physical interchangeability.
4.8
Physical interchangeability
The ability of components outside the system to replace the corresponding components in the system in terms of assembly.
