FDIS Report on voting
34D/1296/FDIS 34D/1304/RVD

Full information on the voting for the approval of this amendment can be found in the report

on voting indicated in the above table.

The committee has decided that the contents of this amendment and the base publication will

remain unchanged until the stability date indicated on the IEC website under

"" in the data related to the specific publication. At this date, the

publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
INTRODUCTION to Amendment 1

The light output of LED light sources depends also on the temperature at which it is operated.

Typically the temperature is controlled by a heat sink on which it is mounted (e.g. luminaire


For this reason, the calculation of the ratio of the electrical parameter (EOF ) will be

introduced in the LED controlgear standards IEC 61347-2-13 and IEC 61347-2-7, as the direct

measurement of EBLF is not practicable.

In particular EOF is defined as the ratio of the current in emergency mode from constant

current controlgear divided by the nominal current of LED (I ):
normal mode
EOF = I / I
I emergency normal mode

Knowing that the light output of an LED light source is nearly directly proportional with the

foreward current flowing through it, it is possible to calculate the luminous flux of the luminaire

in emergency mode by using the EOF or I from constant current controlgear
I emergency

This document contains a proposal for the modification of IEC 60598-2-22 to use the factor

EOF or I in the luminaire.
I emergency

Any non-linearity due to the increased efficacy at lower operation temperature leads to an increased tolerance

of the light output in the emergency mode but always positive.

22.2 Normative references
Delete the reference to IEC 60354-5-56
Add the following new reference:
CIE S025, Test Method for LED Lamps, LED Luminaires and LED Modules
22.3 Terms and definitions
Replace the existing note 1 to entry with the following new note 1 to entry:
Note 1 to entry: PELF = LDL × EBLF

where LDL is the rated luminous flux of fluorescent or discharge lamp, this is taken as the initial lighting design

lumens at 100 h.
Add, at the end of 22.3, the following new terminological entry:
practical emergency light source flux

minimum luminous flux of the light source observed during the rated duration of the

emergency mode
Note 1 to entry: For LED light sources:
a) if EOF is given: PELSF = LDL x EOF
b) if I from constant current controlgear is defined: PELSF = LDL x (I / I )
emergency emergency normal mode

where LDL is the lumen output of the LED module under the condition corresponding to the operation in the

luminaire (identical tp) operated at the same current (I ).
normal mode
Note 2 to entry: This note only applies to the French language.
22.7 Construction

In the first paragraph, replace the last two sentences with the following new text:

In addition, emergency luminaires with automatic testing systems shall comply with the

additional requirements of IEC 62034 as identified in Annex K of IEC 61347-2-7.

In the first paragraph, replace the text "… IEC 61347-2-7, IEC 61347-2-3: Annex J,

IEC 61347-2-2, IEC 61347-2-12 and IEC 61347-2-13 as appropriate" with the following new


IEC 61347-2-2, IEC 61347-2-3: IEC 61347-2-7, IEC 61347-2-12 and IEC 61347-2-13 as

appropriate and with the additional safety requirements for electronic controlgear for

emergency lighting in the appropriate annex of the standards (e.g. Annex J of
IEC 61347-2-3).”
Delete the existing third paragraph and add the following new note:
NOTE Installation details can be found in IEC 60364-5-56.

22.17 Photometric data
Replace the existing text with the following new text:

The manufacturer shall make available the intensity distribution data necessary for the

calculation of the emergency lighting installation according to ISO 30061. The intensity data in

emergency mode may be provided in candelas or in relative cd/1 000 lm. If the values are

declared in candelas, the manufacturer shall provide the emergency luminaire rated luminous

flux derived from the intensity distribution table.

Compliance is checked by direct measurements in emergency operating condition taking into

account the test operating condition described in 22.17.3 or by measurements in normal

operating condition and calculation as described in 22.17.2.
Replace "Void" with the following new text:

If values are declared in cd/1 000 lm, the manufacturer shall also provide the reference flux in

emergency mode.

In the case of luminaires with tubular fluorescent lamps or other discharge lamps the

reference flux is the practical emergency light source flux PELF calculated as the rated flux of

the lamp multiplied by the EBLF of the associated emergency ballast.
In the case of luminaires with LED light source the reference flux is:
– the practical emergency light source flux PELSF

The value may be calculated as the light source luminous flux of the LED module (LDL) in

reference condition corresponding to the luminaire (at the same t ) and at rated current

(I ) multiplied by the EOF or (I / I ) of the associated constant
normal mode I emergency normal mode
current emergency controlgear

NOTE 1 In this case the LOR of the luminaire has influence on the calculation of the emergency rated luminaire

– the emergency luminaire rated luminous flux
This value shows the rated luminous flux of the luminaire in normal mode (I )
normal mode
multiplied by the EOF or (I / I ) of the associated constant current
I emergency normal mode
emergency controlgear.
NOTE 2 In this case the LOR of the luminaire is considered as 1.
The factor EOF can only be used under the following conditions:
– The forward current of the LED is controlled by the controlgear only.

– All LEDs mounted in the luminaire are supplied both in normal operating conditions and in

emergency mode.

– The luminaire luminous flux and/or the LED light source luminous flux is measured at

I corresponding to the I of the controlgear (e.g. in the case of a
normal mode normal mode
luminaire to be used with independent controlgear).
– The current in emergency mode is equal or lower than I (EOF equal or lower
normal mode I
than 1).

NOTE 3 The use of emergency output factors different from EOF (e.g. EOF or EOF ) are not part of the scope

of 22.17.2. They can only be used for design purposes and not for testing.

Replace "Void" with the following new text:

Emergency luminaires shall provide at least 50 % of the level declared photometric data

claimed by the manufacturer during operation in emergency mode 5 s after failure of the

normal supply, and full rated photometric performance after 60 s and continuously to the end

of the rated duration of the emerge
