DC or AC supplied electronic controlgear for LED modules - Performance requirements

IEC 62384:2020 is available as IEC 62384:2020 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
IEC 62384:2020 specifies performance requirements for electronic controlgear for use on DC or AC supplies up to 1 000 V (alternating current at 50 Hz or 60 Hz) and with an output frequency which can deviate from the supply frequency, associated with LED modules according to IEC 62031. Controlgear for LED modules specified in this document are designed to provide constant voltage or current. Deviations from the pure voltage and current types do not exclude the gear from this document. This second edition cancels and replaces the first edition published in 2006 and Amendment 1:2009. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- scope extension (direct current from 250 V to 1 000 V);
- new specifications for measuring the power factor for controlgear with settable/non-constant output (for instance, to allow for constant light output);
- deletion of audio frequency requirements;
- selection of current test circuit by module capacitance (instead of selecting by having or not having logic circuitry) plus test circuit setup changes.

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.

International Standard IEC 62384 has been prepared by subcommittee 34C: Auxiliaries for

lamps, of IEC technical committee 34: Lamps and related equipment.
This second edition cancels and replaces the first edition published in 2006 and
Amendment 1:2009. This edition constitutes a technical revision.

This edition includes the following significant technical changes with respect to the previous

edition:
a) scope extension (direct current from 250 V to 1 000 V);

b) new specifications for measuring the power factor for controlgear with settable/non-

constant output (for instance, to allow for constant light output);
c) deletion of audio frequency requirements;

d) selection of current test circuit by module capacitance (instead of selecting by having or

not having logic circuitry) plus test circuit setup changes.

DC OR AC SUPPLIED ELECTRONIC CONTROLGEAR FOR
LED MODULES – PERFORMANCE REQUIREMENTS
1 Scope

This document specifies performance requirements for electronic controlgear for use on DC or

AC supplies up to 1 000 V (alternating current at 50 Hz or 60 Hz) and with an output

frequency which can deviate from the supply frequency, associated with LED modules

according to IEC 62031. Controlgear for LED modules specified in this document are

designed to provide constant voltage or current. Deviations from the pure voltage and current

types do not exclude the gear from this document.

NOTE 1 The tests in this document are type tests. Requirements for testing individual controlgear during

production are not included.

NOTE 2 Requirements for controlgear which incorporate means for varying the output power are under

consideration.

NOTE 3 It can be expected that controlgear complying with this document will ensure satisfactory operation

between 92 % and 106 % of the rated supply voltage, taking into account the specifications of the LED module

manufacturer.
2 Normative references

The following documents are referred to in the text in such a way that some or all of their

content constitutes requirements of this document. For dated references, only the edition

controlgear suitable for LED modules which present low capacitance or no capacitance

connected directly or indirectly to the input terminals

Note 1 to entry: Examples are LED modules with only LEDs or with logic circuits intended for thermal protection,

but not directly modifying the power supplied by the controlgear, or linear voltage regulators.

Note 2 to entry: Typically, capacitances of 100 nF and below are considered low capacitance.

4 General notes on tests
4.1 The tests given in this document are type tests.

The requirements and tolerances permitted by this document are based on testing of a type

test sample submitted by the manufacturer for that purpose. In principle this type test sample

should consist of units having characteristics typical of the manufacturer’s production and be

as close to the production centre point values as possible.

NOTE It can be expected with the tolerances given in this document that products manufactured in accordance

with the type test sample will comply with this document for the majority of the production. Due to the production

spread however, it is inevitable that there will sometimes be products outside the specified tolerances. For

guidance on sampling plans and procedures for inspection by attributes, see IEC 60410.

4.2 For tests which are carried out with a LED module or LED modules, this (these) LED

module(s) shall fulfil the following requirements:

The power of the LED module(s) when measured at its (their) rated voltage or rated current

(direct current and/or alternating current) shall not differ from the rated power by more than

+6 % and –0 %.

4.3 The tests shall be carried out in the order of the clauses, unless otherwise specified.

4.4 One specimen shall be subjected to all the tests.

4.5 In general all the tests are made on each type of controlgear or, where a range of

similar controlgear is involved for each rated power in the range or on a representative

selection from the range as agreed with the manufacturer.

4.6 The tests shall be made under the conditions specified in Clause A.1. Since up to now

data with regard to LED modules have not been published in an IEC standard, they shall be

made available by the LED module manufacturer.

4.7 All controlgear covered by this document shall comply with the requirements of

IEC 61347-2-13.

4.8 The tests shall be carried out with the length of the output cable of both 20 cm and

200 cm unless otherwise declared by the manufacturer.

5 Classification
5.1 Classification according to the load
a) Single value load controlgear

This type of controlgear is designed for use with one specific output power only, which

may be dissipated by one or more LED modules.
b) Multiple value load controlgear

This type of controlgear is designed for use with one or more LED modules with a total

load within the declared power range.
5.2 Classification according to the output voltage

b) Controlgear without a stabilized output current.
6 Marking
6.1 Mandatory marking
6.1.1 Controlgear shall be clearly marked as follows:
Circuit power factor, for example λ = 0,9.

For controlgear where the power factor is not constant all over the rated output range and/or

controlgear with a supply voltage range, the power factor may be different for different

combinations of supply voltage and output power. In this case the controlgear shall be marked

with a range of power factor values, for example λ = 0,8 – 0,9.

If the power factor is less than 0,95 leading, it shall be followed by the letter "C", for example

λ = 0,9 C.

6.1.2 In addition to the above mandatory marking, the following information shall either be

given on the controlgear or made available in the manufacturer’s catalogue or the like:

a) if applicable: limits of the permissible temperature range;

b) if applicable: an indication that the controlgear has a stabilized output voltage;

c) if applicable: an indication that the controlgear has a stabilized output current;

d) if applicable: an indication that the controlgear is suitable for operation with a mains

supply dimmer;

e) if applicable: an indication of the operation mode, for example phase control;

f) if applicable: P , the rated minimum output power for the proper operation of the

rated_min
controlgear.
NOTE P can be combined with P in only one marking. e.g. P = 20 W…60 W.
rated_min rated rated
6.2 Optional marking

The following information may either be given on the controlgear or made available in the

manufacturer’s catalogue or the like:
a) total circuit power;
---------------------- Page: 9 ----------------------
– 8 – IEC 62384:2020  IEC 2020

b) if applicable: a symbol which indicates that the controlgear is a short-circuit proof type

(the symbol is under consideration).
7 Output voltage and current
7.1 Starting and connecting requirements

After starting or connecting a LED module, the output should be within 110 % of its rated

value within 2 s. Maximum current or maximum voltage shall not exceed the values given by

the manufacturer. This performance is tested with the minimum rated power.

NOTE If the output voltage is AC, 110 % is the percentage of the RMS value, if DC, 110 % is the percentage of

the DC value.
7.2 Voltage and current during operation

For controlgear having a non-stabilized output voltage, when supplied with the rated supply

voltage, the output voltage shall not differ by more than ±10 % from the rated voltage of the

LED modules. For controlgear having a stabilized output voltage, when supplied at any supply

voltage between 92 % and 106 % of the rated supply voltage, the output voltage shall not

differ by more than ±10 % from the rated voltage of the LED modules.

For controlgear having a non-stabilized output current, when supplied with the rated supply

voltage, the output current shall not differ by more than ±10 % from the rated current of the

LED modules. For controlgear having a stabilized output current, when supplied at any supply

voltage between 92 % and 106 % of the rated supply voltage, the output current shall not

differ by more than ±10 % from the rated current of the LED modules.

Multiple load controlgear shall be tested with both the minimum and maximum load.

7.3 Capacitive load requirement

The LED module or any additional control unit connected to the controlgear may contain

capacitors for control and/or driving circuitry on the modules and current pulses may be

generated when connecting the LED module to the controlgear. Controlgear overcurrent

detection shall not be disturbed during the starting process of the controlgear.

For test conditions, see Clause A.2. Figure A.1a) describes a test circuit during the starting

process of the controlgear and Figure A.1b) describes a test circuit for connecting the load

during steady state operation.

The test according to Figure A.1b) may be waived under the condition that it is specified by

the manufacturer in the product information of the controlgear that the LED module must be

connected prior to starting the controlgear in order to ensure proper starting of the LED

module.

If the load detection circuit of the controlgear does not allow operation with pure resistive

load, the resistor R is to be substituted with equivalent LED load.

Compliance: The controlgear overvoltage detection shall not act during the starting phase or

when connecting the load in the steady state phase.
8 Total circuit power

At rated voltage, the total circuit power shall not be more than 110 % of the value declared by

the manufacturer, when the controlgear is operated with LED module(s).
---------------------- Page: 10 ----------------------
IEC 62384:2020  IEC 2020 – 9 –
9 Circuit power factor

The measured circuit power factor shall not be less than the marked value by more than 0,05

when the controlgear is operated at the rated output power range with LED module(s) and the

whole combination is supplied with rated voltage and frequency.

For controllable controlgear, the power factor is measured with the controlgear adjusted to

provide the maximum output power.

Controlgear designed to provide, in combination with a LED module, constant luminous flux,

are measured with a load not using the rated output power at 0 h, but with the controlgear

providing the maximum output power.

The DUT may be specially prepared in a way that the output power is set to the maximum

value compensating the luminous flux depreciation of the load at the end of life.

For controlgear with a supply voltage range, the test shall be performed with the combination

of supply voltage range and output power range which gives the lowest and highest power

factor (e.g. minimum supply voltage, maximum rated output power and maximum supply

voltage, minimum rated output power). The measured power factors shall not be less than the

lowest and highest marked values by more than 0,05 respectively.
10 Supply current

At rated voltage, the supply current shall not differ by more than +10 % from the value marked

on the controlgear or declared in the manufacturer’s literature, when that controlgear is

operated on its rated power with LED module(s).
11 Operational tests for abnormal conditions
The controlgear shall not be damaged under the following conditions.
a) Test without LED module(s) inserted

The controlgear shall be supplied with rated voltage for 1 h without LED module(s)

inserted. At the end of this test, the LED module(s) shall be connected and shall operate

normally.
b) Test for reduced LED module resistance
Under consideration.
c) Tests for short-circuit proof controlgear
The controlgear is short-circuited for 1 h.
The 1 h test shall be completed also in the case of a thermal protection acting.

After these tests and after restoration of a possible protecting device, the controlgear shall

function normally.

12 Endurance

12.1 The controlgear shall be subjected to a temperature cycling shock test and a supply

voltage switching test as follows:
a) Temperature cycling shock test

The non-energized controlgear shall be stored firstly at –10°C or if the controlgear is

marked with a lower value, at that value for 1 h. The controlgear is then moved into a

cabinet having a temperature of t and stored for 1 h. Five such temperature cycles shall

be carried out.
b) Supply voltage switching test

At rated supply voltage the controlgear shall be switched on and off for 30 s. The cycling

shall be repeated 200 times with no load and 800 times under maximum load conditions.

LED modules failing during this test shall be replaced immediately.

At the end of these tests the controlgear shall operate an appropriate LED module or LED

modules correctly for 15 min.

12.2 The controlgear shall then be operated with an appropriate LED module(s) at rated

supply voltage and at the ambient temperature which produces t , until a test period of 200 h

has passed. At the e
