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.

INTRODUCTION
IEC 62386 contains several parts, referred to as series. The 1xx series includes the basic
specifications. Part 101 contains general requirements for system components, Part 102
extends this information with general requirements for control gear and Part 103 extends it
further with general requirements for control devices.
The 2xx parts extend the general requirements for control gear with lamp specific extensions
(mainly for backward compatibility with Edition 1 of IEC 62386) and with control gear specific
features.
The 3xx parts extend the general requirements for control devices with input device specific
extensions describing the instance types as well as some common features that can be
combined with multiple instance types.
This first edition of IEC 62386-218 is intended to be used in conjunction with
IEC 62386-101:2014, IEC 62386-101:2014/AMD1:—, IEC 62386-102:2014 and
IEC 62386-102:2014/AMD1:—. The division into separately published parts provides for ease
of future amendments and revisions. Additional requirements will be added as and when a
need for them is recognized.
The setup of the standards is graphically represented in Figure 1 below.

This document, and the other parts that make up the IEC 62386-200 series, in referring to any
of the clauses of IEC 62386-1XX, specifies the extent to which such a clause is applicable;
the parts also include additional requirements, as necessary.
Where the requirements of any of the clauses of IEC 62386-1XX are referred to in this
document by the sentence “The requirements of IEC 62386-1XX, Clause “n” apply”, this
sentence is to be interpreted as meaning that all requirements of the clause in question of
Part 1XX apply, except any which are clearly inapplicable.
The standardization of the control interface for control gear is intended to achieve compatible
co-existence between electronic control gear and lighting control devices, below the level of
building management systems. This document describes a method of implementing control
gear.

9.2.2 Standard dimming curve
The standard dimming curve is the dimming curve as defined in IEC 62386-102:2014 and
IEC 62386-102:2014/AMD1:—.
9.2.3 Linear dimming curve
If the linear dimming curve is selected, an “actualLevel” greater than or equal to 1 and
less than or equal to 254 shall be translated into light output according to
actualLevel
Light output (actualLevel)= ×100%

The light output is expressed relative to the maximum possible light output of a given
control gear-lamp combination. The dimming curve starts at 0,39 % for “actualLevel” equal to
0x01 and ends at 100 % for “actualLevel” equal to 0xFE. The dimming curve is strictly
monotonic, and the relative accuracy shall be ±½ step. This shall be tested using a fade,
excluding the physical minimum level (PHM).

9.3 Behaviour when changing dimming curves
The control gear shall store levels in combination with the active dimming curve. This allows
the control gear to always be able to reproduce the exact light output requested by the
application controller, since the level and dimming curve combined are needed to calculate
the light output. This includes, but is not limited to, the PHM and the following variables as
defined in IEC 62386-102:2014 and IEC 62386-102:2014/AMD1:—:
• “lastActiveLevel”,
• “lastLightLevel”,
• “powerOnLevel”,
• “sytemFailureLevel”,
• “minLevel”,
• “maxLevel”,
• “actualLevel”,
• “targetLevel”,
• “sceneX”.
Similar variables used in combination with levels introduced in other parts of the IEC 62386
series shall be included.
Changing the dimming curve shall have no effect either on the light output or on any of the
stored levels.
If “dimmingCurve” is changed during a running fade, the change shall only take effect after the
running fade has finished.
9.4 Using stored levels
If a stored level is queried, the level reported shall be the level that matches the closest
based on the active dimming curve. The level shall be calculated as follows:
• calculate the light output percentage based on both the level and dimming curve stored
previously;
• determine the closest matching light output percentage according to the active dimming
curve;
• report the corresponding level for the matching light output percentage.
Since conversion is used only for reporting, changing the dimming curve shall not reduce the
resolution or change stored levels. See Annex A.
When stored levels are recalled, the control gear shall use the combination of the level and
the dimming curve stored to calculate “targetLevel” based on the above rules. This might
introduce a small error between the light output according to the active dimming curve, and
the light output according to the stored dimming curve. It is up to the manufacturer to decide
which light level will be used, the rounded value or the exact value.
All further actions such as fading shall be executed using the currently active dimming curve.
EXAMPLE 1: The level with the standard dimming curve active (“dimmingCurve” = 0) is set to 8, which is 0,121 %.
After switching to the linear dimming curve (“dimmingCurve” = 1) the actual level is queried. This reports the
nearest level in the linear curve, which is 1 or 0,39 %. Switching back to the standard curve reports 8 again (no
conversion loss).
EXAMPLE 2: The level with the standard dimming curve active (“dimmingCurve” = 0) is set to 252, which is
94,686 %. After switching to the linear dimming curve (“dimmingCurve” = 1) the actual level is queried. This reports
the nearest level in the linear curve, which is 241 or 94,882 %. If now a step up is performed, this is executed in
the linear curve, going to 242, which is 95,276 %. Changing back to the standard dimming curve and querying the
actual level, the answer is still be 252 since this is the closest matching value in the standard dimming curve.
