Add a new Annex I as follows:
Temperature in the chamber

Annex I
(normative)
Lumen maintenance test conditions for LED light sources

I.1 Ageing
LED light sources shall be aged at their test voltage for 48 h under the operating conditions
specified in Clause I.3. LED light sources which fail during the ageing period shall be omitted
from the test results.
I.2 Test voltage
Measurements shall be carried out at a test voltage of:
• 6,75 V for products intended for a 6 V board voltage;
• 13,5 V for products intended for a 12 V board voltage;
• 28 V for products intended for a 24 V board voltage.
The applied voltage shall be a stable d.c.
If the LED light source is intended to be operated by an electronic light source control gear,
the test voltage shall be applied to the input terminals of the control gear. In this case, the
output of the electronic light source control gear, e.g. voltage, electrical current, power,
operating mode, etc. shall be described in the test report.
NOTE The test voltage is deemed to be stable when the momentary fluctuations do not exceed 1 % and the
deviation of the average over the test period does not exceed 0,5 % of the specified value.
I.3 Operating conditions
I.3.1 Test rack
LED light sources shall be operated on a vibration-free test rack.
I.3.2 LED light sources with integrated thermal management
LED light sources with integrated thermal management shall be installed in a chamber with
the following characteristics:
– well-mixed air, but no excessive forced convection across the light source;
– ambient air temperature in the chamber: 25 °C ± 10 °C.
I.3.3 LED light sources with external thermal management
LED light sources, for which the thermal management is intended to be achieved in
conjunction with the luminaire/device or a separate thermal management component, shall be
operated at the specified base temperature T . The base temperature T shall be included in

p p
the test report and shall be part of the lumen maintenance declaration by the manufacturer.
NOTE Control of the T temperature during testing can be achieved by active or passive methods e. g. a heat-
p
sink, a heat-sink combined with a cooling fan or a Peltier-cooling-element.
Examples for possible product data are given in Table I.1.

I.4 Switching cycle
I.4.1 Single-function LED light sources
I.4.1.1 LED light sources for continuous operation
LED light sources shall be switched off twice daily for periods of not less than 15 min, such
periods not being considered as part of the life.
I.4.1.2 LED light sources for intermittent operation
LED light sources for intermittent operation as used in direction indicators shall be operated in
the following switching cycle:
• 115 min continuous on or flashing, as appropriate;
• 5 min off;
• flashing frequency: 90/min; on/off ratio 1:1.
The whole flashing operation time is considered as life.
I.4.2 Dual-function LED light sources for headlamps
The functions shall be operated alternately according to the following cycle and starting with
the lower beam function:
• passing-beam function: 15 h on/45 min off;
• driving-beam function: 7,5 h on/45 min off.
The lifetime values for the light source are determined by the lower performing of the two
functions.
The off periods are not considered as part of the life.
NOTE The operation of the passing-beam function represents two-thirds of the total life, the operation of the
driving-beam function one-third.
I.4.3 Multiple-function LED light sources for light signalling equipment
Lumen maintenance testing may be carried out either for each function separately, or with all
functions operated simultaneously or with the functions operated alternately.
In case of an alternate operation, each function shall be operated with a minimum on-period
of 10 h.
– 12 – 60810 Amend.2 © IEC:2013
If different operating conditions (e. g. dimming) are used for the same LED light source in
order to fulfil different functions, lumen maintenance testing may be carried out at the most
onerous conditions.
For LED light sources for continuous operation, the switching cycle shall be as specified in
I.4.1.1.
For LED light sources for intermittent operation, the switching cycle shall be as specified in
I.4.1.2.
I.5 Lumen maintenance measurements
Tests may be interrupted for determination of the lumen maintenance.
Lumen maintenance measurements should be carried out at regular intervals, at a minimum
time interval of 1 000 h.
For the measurement of the luminous flux, an integrating method shall be used. The LED light
source shall be operated in a dry and still atmosphere at an ambient temperature of
23 °C ± 5 °C.
LED light sources, for which the thermal management is intended to be achieved by additional
provisions, shall be operated at the specified performance temperature T .
p
Measurements shall be carried out when photometric stability has occurred.
The moment at which the photometry is stable is defined as the point in time at which the
variation of the photometric value is less than 3 per cent within any 15-minute period.
I.6 Colour measurement
The colour of the emitted light shall be measured, using an integrating method, at the same
time as the lumen maintenance measurements and under the same conditions as specified in
Clause I.5.
The colour shall be expressed in CIE-coordinates and shall remain within the respective
colour boundaries as given in 2.4 of IEC 60809 (for colour specification, see also ECE R48,
