LIGHTING SYSTEMS – GENERAL REQUIREMENTS

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.

• provide appropriate electrical insulation towards system integration for electrical safety
assurance;
• provide appropriate protection measures towards system integration for functional safety
and information security;
• provide appropriate interfaces, such as communication interfaces, towards system
integration for the expected system performance and functionality.
Compliance is checked by inspection of the documentation and by carrying out the tests of
Clause 5 to Clause 10 11.
5 Electrical safety
Lighting systems require additional safety requirements at the system level. These
requirements apply in addition to the product safety requirements that can be found in the
product specific standards.
The electrical safety requirements of lighting systems at the system level shall follow
IEC TS 63117.
6 Functional safety
Lighting systems often comprise many different products (luminaire, sensor, controllers, touch
panels and other human interfaces, etc.) which are connected through communication cabling
or wirelessly, where the light output can be varied based on the input from sensors or users.
Malfunction of the interaction of system components can create unsafe lighting conditions.
When operating, they should incur no unacceptable risks.
Functional safety requirements of lighting systems shall follow IEC TS 63117.
7 Information security
Lighting systems often utilize communication, data transfer and data storage functions. The
data and information can be sensitive and/or private. Lighting systems can also be applied
within an environment demanding (a) higher security level(s). These lighting systems shall be
applied with an appropriate level of information security.
Information security aspects shall be considered from the start of the design of a lighting system,
throughout its service life, and at end-of-life-stage. Whether measures to provide information
security are to be included should be checked against regulatory and application requirements,
see Figure 1.

11 Classification of lighting systems
11.1 General
According to the system structure, lighting systems can be classified into three categories, as
follows:
• lighting systems consisting of standalone luminaire(s);
• autonomous lighting systems;
• centrally controllable lighting systems.
See 11.2 to 11.4 for the description of the different categories.
See 11.5 for the typical capacities of lighting systems in different categories.
11.2 Lighting system consisting of standalone luminaire(s)
A lighting system consisting of a standalone luminaire is a luminaire that does not communicate
with other luminaires or a central controller for setting light properties (e.g. on/off, dimming) or
for the exchange of information. It can have the capability to communicate with other devices
for setting configuration parameters or setting light properties (e.g. on/off, dimming) or
exchange of information. An example of a lighting system consisting of one standalone
luminaire is shown in Figure 2.

Figure 2 – Example of lighting system consisting of a standalone luminaire
11.3 Autonomous lighting system
The autonomous lighting system consists of two or more luminaires that can communicate with
each other for the purpose of adjusting the light properties of the luminaires. This network of
luminaires is characterized by having no central control possibilities.
These luminaires have at least one communication network that is intended to exchange
information between luminaires to control the light properties. These luminaires can also have
the communication capabilities of a standalone luminaire. An example of autonomous lighting
system is shown in Figure 3.
© IEC 2023
Figure 3 – Example of autonomous lighting system
11.4 Centrally controllable lighting system
The centrally controllable lighting system consists of one or more luminaires that can
communicate with a central controller and in the case of multiple luminaires, can have the ability
to communicate between luminaires directly like in an autonomous lighting system and can
have the communication capabilities of a standalone luminaire. An example of centrally
controllable lighting system is shown in Figure 4.

Figure 4 – Example of centrally controllable lighting system
11.5 Typical capacities of lighting systems in different categories
The implementations of adaptive lighting controls and functionalities on lighting systems are
specified according to the purpose and environmental conditions of the application. Table 1
gives examples of such functionalities and characteristics for each category of lighting system.
