AMENDMENT 2
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 document may be the subject of patent

rights. IEC shall not be held responsible for identifying any or all such patent rights.

Amendment 2 to IEC 61347-2-7:2011 has been prepared by subcommittee 34C: Auxiliaries for

lamps, of IEC technical committee 34: Lighting.

20.2 Requirements for LED lamp controlgear
20.2.1 Constant current LED controlgear: EOF and I
I emergency

Replace the existing Subclause 20.2.1, added by Amendment 1, with the following new text:

LED light sources show a direct relation between forward current and light output with only a

slight deviation due to an improved efficacy when operated at lower temperatures.

The emergency output factor of the forward current, EOF , is the ratio of the average current

measured in emergency mode (I ) and the average forward current measured at rated

emergency
conditions (I ).
normal mode
Compliance is checked by the following test set-up:

For compliance measurements of EOF the controlgear shall be operated with a load producing

the maximum and the minimum of the output voltage range (or power).
Electronic controlgear provided with or without ESSSs:

For the measurement of I and EOF voltages representative of a fully charged battery

emergency I

and the battery voltage present just before the lamp extinguishes are used as follows:

V – Full charge battery voltage per cell dependent on battery type as follows:
NiCd 1,35 V per cell;
NiMH 1,35 V per cell;
Pb 2,10 V per cell;
Li(NiCoMn)O 4,0 V;
LiFePO 3,65 V
LTO 2,80 V;

(values given by default and can be different depending on the battery manufacturer's

declaration of design).
EDLC – Full charge EDLC voltage measured after full charge;

V – End of capacity battery voltage per cell dependent on battery type as follows:

min
NiCd 1,10 V;
NiMH 1,10 V;
Pb 1,80 V;
3,1 V;
Li(NiCoMn)O
LiFePO 2,00 V;
LTO 1,65 V.

(values given by default and can be different depending on the battery manufacturer's

declaration of design).

EDLC – the lowest value measured at the end of emergency operation immediately before the

light source extinguishes.

Where the controlgear cut off voltage is above these voltages, the cut off voltage becomes V .

min
Measurement of I shall be made at an ambient temperature of 25 °C. The first
emergency

measurement of the output current is made at V at 5 s and at 60 s after the application of the

d.c. voltage.
The second measurement of the output current is made at V .
min
The lower of the current measured at 60 s and V or V shall be retained as I and
1 min emergency

shall reach at least the declared value for I and EOF when compared with the output

emergency I

current (I ) of the controlgear measured under normal conditions with the same load.

21 Changeover operation

Insert, between the existing first and second paragraphs of Clause 21, modified by

Amendment 1, the following new paragraphs:

In the case of a rated supply voltage range, then changeover from normal to emergency mode

shall occur at not less than 0,6 times the maximum of the rated supply voltage range. It shall

not occur at greater than 0,85 times the minimum of the rated supply voltage range.

Controlgear with a selectable input voltage should be tested for changeover operation at each

voltage setting.
In NOTE 1, replace "batteries" with "ESSSs" and "may" with "can".

In the first sentence of the last existing paragraph, modified by Amendment 1, replace "rated

supply voltage" with "minimum rated supply voltage".
Replace the existing NOTE 2 with the following new NOTE 2:

NOTE 2 In Japan, changeover from normal to emergency mode at not less than 0,4 times the rated supply voltage

is accepted. In the case of universal controlgear without a selectable input voltage, changeover from normal to

emergency mode at not less than 0,4 times the minimum of the supply voltage range is accepted.

22 Recharging device

Replace the existing Clause 22, modified by Amendment 1, with the following new Clause 22:

The recharging device, if provided, shall provide the rated charge performance as declared by

the controlgear manufacturer to charge the ESSS within 24 h
