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
surface).
For this reason, the calculation of the ratio of the electrical parameter (EOF ) will be
x
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
I
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.

22.17 Photometric data
22.17.1
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.
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
p
(I ) multiplied by the EOF or (I / I ) of the associated constant
normal mode I emergency normal mode
.

NOTE 1 In this case the LOR of the luminaire has influence on the calculation of the emergency rated luminaire
flux.
– 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:
I
– 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
I U P
of 22.17.2. They can only be used for design purposes and not for testing.
