Limits and methods of measurement of radio disturbance characteristics of electrical lighting and similar equipment

CISPR 15:2018 applies to the emission (radiated and conducted) of radiofrequency disturbances from:
- lighting equipment (3.3.16);
- the lighting part of multi-function equipment where this lighting part is a primary function;
- UV and IR radiation equipment for residential and non-industrial applications;
- advertising signs;
- decorative lighting;
- emergency signs.
Excluded from the scope of this document are:
- components or modules intended to be built into lighting equipment and which are not user-replaceable;
- lighting equipment operating in the ISM frequency bands (as defined in Resolution 63 (1979) of the ITU Radio Regulation);
- lighting equipment for aircraft and airfield facilities (runways, service facilities, platforms);
- video signs;
- installations;
- equipment for which the electromagnetic compatibility requirements in the radio-frequency range are explicitly formulated in other CISPR standards, even if they incorporate a built-in lighting function.
The frequency range covered is 9 kHz to 400 GHz. No measurements need to be performed at frequencies where no limits are specified in this document.
Multi-function equipment which is subjected simultaneously to different clauses of this document and/or other standards need to meet the provisions of each clause/standard with the relevant functions in operation.
For equipment outside the scope of this document and which includes lighting as a secondary function, there is no need to separately assess the lighting function against this document, provided that the lighting function was operative during the assessment in accordance with the applicable standard. The radiated emission requirements in this document are not intended to be applicable to the intentional transmissions from a radio transmitter as defined by the ITU, nor to any spurious emissions related to these intentional transmissions.
Within the remainder of this document, wherever the term "lighting equipment" or "EUT" is used, it is meant to be the electrical lighting and similar equipment falling in the scope of this document as specified in this clause. This ninth edition cancels and replaces the eighth edition published in 2013 and its Amendment 1:2015. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) full editorial revision and restructuring;
b) the restriction to mains and battery operation is deleted in the scope;
c) radiated disturbance limits in the frequency range 300 MHz to 1 GHz have been introduced;
d) the load terminals limits and the CDNE (alternative to radiated emissions) limits have changed;

INTERPRETATION SHEET 1
This interpretation sheet has been prepared by subcommittee CISPR F: Interference relating to
household appliances tools, lighting equipment and similar apparatus, of IEC technical
committee CISPR: International special committee on radio interference.
The text of this interpretation sheet is based on the following documents:

CISPR 15 interpretation sheet on the worst-case mode of operation
Introduction
Subclause 7.5 specifies the operating modes of lighting equipment that must be considered
during an emission test. A few examples are given to support the explanation of what ‘different
operating modes’ means. The list of examples is of course not exhaustive. Apparently, the
example of ‘colour shifting’ is not clear enough and it is sometimes interpreted as if any possible
colour and/or correlated colour temperature (CCT) setting that lighting equipment may produce
shall be assessed during measurements. Many types of LED lighting may be set in many
different colours and CCTs. Compared to other operational-mode related influence quantities
such as light level regulation, flashing or radio communication, the risk of not capturing the
maximum level of electromagnetic (EM) disturbances due to different colour or CCT settings is
very small, provided that all channels of a LED driver used to change colour or CCT are
operative. The ‘colour shifting’-example was meant for example for a mode where the light
output continuously switches from one colour to another with a certain repetition frequency (e.g.
applied for entertainment, events etc.), instead of emitting a single stable colour and/or CCT.
ICS 33.100.10
– 2 – CISPR 15:2018/ISH1:2019  IEC 2019
Question
What is the meaning of example ‘colour shifting’ as mode of operation to be considered during
testing? What colour and/or colour temperature should be selected in case lighting equipment
can be set in a wide range of colours and/or CCTs?
Interpretation
The example ‘colour shifting’ in the first paragraph of 7.5 of CISPR 15:2018 must not be
interpreted as if any possible colour and/or CCT setting that lighting equipment may produce
shall be assessed during measurements.
Generally, according to 7.5 the worst case shall be found by prescanning every mode of
operation over at least one repetition interval of the specific mode.
Alternatively, measurements can be performed using the setting(s) that are expected to produce
the highest amplitude emissions relative to the limit; and, the reasons for the selection shall be
given in the test report.
A reason could be that highest level of electromagnetic (EM) disturbances will be captured if all
channels of a LED driver used to create different colours and/or CCTs are operative. The
number of channels applied depends on the LED-driver/LED-light-source architecture. Often,
maximum EM disturbances can be achieved by selecting a white colour and/or a CCT setting
in the middle of the specified CCT range.
EXAMPLE Colour variation and CCT variation may be achieved using a 5-channel LED driver powering three LED strings for
colour (RGB) setting and two cool white and warm white LED strings for CCT setting. Hence, in case the lighting equipment under
test is capable to operate at different colours and/or CCTs, a white colour and/or a single CCT in the middle of the specified CCT
range may be selected .

7.4 of CISPR 15:2018, also still applies.

CISPR 15 interpretation sheet on the worst-case mode of operation
Introduction
Subclause 7.5 specifies the operating modes of lighting equipment that must be considered
during an emission test. A few examples are given to support the explanation of what ‘different
operating modes’ means. The list of examples is of course not exhaustive. Apparently, the
example of ‘colour shifting’ is not clear enough and it is sometimes interpreted as if any possible
colour and/or correlated colour temperature (CCT) setting that lighting equipment may produce
shall be assessed during measurements. Many types of LED lighting may be set in many
different colours and CCTs. Compared to other operational-mode related influence quantities
such as light level regulation, flashing or radio communication, the risk of not capturing the
maximum level of electromagnetic (EM) disturbances due to different colour or CCT settings is
very small, provided that all channels of a LED driver used to change colour or CCT are
operative. The ‘colour shifting’-example was meant for example for a mode where the light
output continuously switches from one colour to another with a certain repetition frequency (e.g.
applied for entertainment, events etc.), instead of emitting a single stable colour and/or CCT.
ICS 33.100.10
– 2 – CISPR 15:2018/ISH1:2019  IEC 2019
Question
What is the meaning of example ‘colour shifting’ as mode of operation to be considered during
testing? What colour and/or colour temperature should be selected in case lighting equipment
can be set in a wide range of colours and/or CCTs?
Interpretation
The example ‘colour shifting’ in the first paragraph of 7.5 of CISPR 15:2018 must not be
interpreted as if any possible colour and/or CCT setting that lighting equipment may produce
shall be assessed during measurements.
Generally, according to 7.5 the worst case shall be found by prescanning every mode of
operation over at least one repetition interval of the specific mode.
Alternatively, measurements can be performed using the setting(s) that are expected to produce
the highest amplitude emissions relative to the limit; and, the reasons for the selection shall be
given in the test report.
A reason could be that highest level of electromagnetic (EM) disturbances will be captured if all
channels of a LED driver used to create different colours and/or CCTs are operative. The
number of channels applied depends on the LED-driver/LED-light-source architecture. Often,
maximum EM disturbances can be achieved by selecting a white colour and/or a CCT setting
in the middle of the specified CCT range.
EXAMPLE Colour variation and CCT variation may be achieved using a 5-channel LED driver powering three LED strings for
colour (RGB) setting and two cool white and warm white LED strings for CCT setting. Hence, in case the lighting equipment under
test is capable to operate at different colours and/or CCTs, a white colour and/or a single CCT in the middle of the specified CCT
range may be selected .
