3.1.1
lighting
illumination
application of light to a scene, objects, or their surroundings
[SOURCE: IEC 60050-845:2020,845-29-001, modified – The note has been deleted.]
3.1.2
adaptive lighting
lighting responding to circumstances or according to predefined conditions, while maintainingthe lighting quality within the specified requirements for these circumstances or conditions
Note 1 to entry: The requirements can focus on different aspects such as energy efficiency，dynamic user needs,visual tasks or ambience.
Note 2 to entry. The terms “smart lighting”and “intelligent lighting”are sometimes used with a similar meaning.[SOURCE: IEC 60050-845:2020,845-29-027]
3.1.3
integrative lighting
lighting integrating both visual and non-visual effects,and producing physiological and/orpsychological benefits upon humans
Note 1 to entry: The term “integrative lighting”applies only to humans.
Note 2 to entry: Lighting primarily for therapeutic purpases (lighttherapy) is not included.Note 3 to entry: The term “human-centric lighting”is used with a similar meaning.
[SoURCE: IEC 60050-845:2020,845-29-028]
3.2 Lighting systems
3.2.1
system
set of interrelated items that collectively fulfil a requirement
Note 1 to entry: A system is considered to have a defined real or abstract boundary.
Note 2 to entry: External resources (from outside the system boundary) can be required for the systems to operate.
Note 3 to entry: A system structure can be hierarchical, e. g. system, subsystem, component, etc.
Note 4 to entry: Conditions of use and maintenance can be expressed or implied within the requirement.
[SOURCE: IEC 60050-192:2015, 192-01-03, modified – The verbal forms “may” and “should” in the notes have been replaced with “can”. The domain of application has been removed.]
3.2.2
lighting system
system (IEV 192-01-03) designed to provide lighting (IEV 845-29-001)
Note 1 to entry: A lighting system can be dedicated to
a) the support of one or more specfied visual tasks under specified conditions considering other requirements suchas human comfort,safety， the appearance of the surrounding environment and energy consumption;
b)the support of other than human tasks.
Note 2 to entry.:Alighting system can include a set of light sources,other physicalcomponents，communicationprotocols，user interfaces,software and networks to provide central control and monitoring functions.
Note 3 to entry: The light source(s) and the related equipment can be integrated in a single item,e.g. an LEDmodule,a lamp or a luminaire.
Note 4 to entry: A lighting system can be networked to provide central or remote control and monitoring functions.Note 5 to entry: A lighting system can be connected to or integrated with other systems or devices.

3.2.3
adaptive lighting system
lighting system designed for adaptive lighting
3.2.4
integrative lighting system
lighting system designed for integrative lighting3.2.5
lighting system network
interconnection (wired or wireless) between lighting system devices used for internal or externalcommunication
Note 1 to entry: A lighting system network can carry digital data as well as analogue signals.3.2.6
energy performance
<of a lighting system> calculated or measured amount of weighted net energy actually used orestimated to meet different needs associated with a standardized operation of a lighting system(IEV 845-27-010)
