Set-up to measure the luminous intensity distribution
Luminous intensity data is recorded for the major function with a standard photo-goniometer.

Cumulative luminous flux distribution
Measurement set-up
This test is intended to determine the cumulative luminous flux within defined solid angles of
the luminous intensity distribution.
Goniophotometers of type I or II according to CIE publication No 70 -1987 with the capability
of turning the light source around two axes perpendicular to the axis of light emission can be
used. The intersection of the reference axis and the parallel plane to the reference plane in
distance e is used as the coordinate system origin.

javascript:void(0);
The light source is mounted on a flat plate with the corresponding mounting lug features. The
plate is mounted to the goniometer table by a bracket in such way, that the reference axis of the
light source lines up with the measurement axis of the goniometer. The corresponding
measurement set-up is described in Figure 4.
Category LW2 — Sheet LW2/4
Cumulative luminous flux distribution
Measurement and calculation procedure
Data shall be recorded for the specified base temperature Tb from Table 1 at the location shown
in Fig. 5.
Luminous intensity distribution data shall be recorded within a solid angle of -40° < α < +40°
and -40° < β < +40°. The measurement distance shall be chosen in such manner that the
detector is located in the far field of the light distribution. An angular step size of 1° or less is
required.
After the measurement, the cumulative luminous flux distribution shall be calculated from the
recorded data for various solid angles as specified in Table 3 according to CIE publication 84-
1989, Section . Subsequently, the distribution shall be normalised to the total luminous flux
determined for -40° < α < +40° and -40° < β < +40. The data shall comply with the tolerance
band defined in Table 3.
In order to secure a symmetrical distribution within each solid angle in Table 3 the luminous
flux determination shall be done independently for all 4 quadrants and flux values shall not
differ by more than 15 %.

and standard lamps

– 25° < α, β < +25° 91 95
– 30° < α, β < +30° 97 100
– 35° < α, β < +35° 98 100
– 40° < α, β < +40° 100 (by definition)
The cumulative luminous flux distribution of the minor function may be verified by measuring
the ratio of major and minor function under a fixed angle and multiplication of this factor with
the luminous flux of the major function.
In case of doubt that cumulative luminous flux distributions of major and minor function differ,
the procedure as described above for the major function shall be repeated for the minor
function.
Thermal interface geometry
The LW2 thermal interface is located within the reference plane (shaded area in Figure 5) and
described in detail in IEC Publication 60061 as indicated in Table 1 on sheet LW2/1. It shall be
attached to an appropriate heat sink or thermal management system.
The luminous flux given in Table 1 shall be achieved once the base temperature Tb measured at
the location shown in Figure 5 is stabilised.

the approval code indicates that the approval was granted in accordance with the requirements
of Regulation No 128 (*1) in its original form.
(*1) Not requiring changes in the approval number.
ANNEX 4
METHOD OF MEASUREMENT OF ELECTRICAL AND PHOTOMETRICAL
CHARACTERISTICS
Light sources of all categories with integrated heatsink shall be measured at ambient
temperature of (23 ± 2) °C in still air. For these measurements the minimum free space as
defined in the data sheets shall be maintained.
Light sources of all categories with definition of a temperature Tb shall be measured by
stabilising the Tb-point at the specific temperature defined on the category data sheet.
1. Luminous flux
luminous flux measurement using an integrating
method shall be made
(a) In case of an integrated heatsink after 1 minute and after 30 minutes of operation
or
(b) After stabilisation of the temperature at the Tb point.
luminous flux values, as measured after
(a) 30 minutes, or
(b) Stabilisation of temperature Tb
Shall comply with the minimum and maximum requirements.
In case of (a) this value shall be in between 100 per cent and 80 per cent of the value
measured after 1 minute.
have to be carried out at relevant test
voltage and at the minimum and maximum values of
the relevant voltage range. Unless specified more
tightly on the data sheet the following deviation of the
luminous flux at the tolerance interval limits shall not
be exceeded.

12 12,0 14,0
24 24,0 28,0

2. Normalised luminous intensity/cumulative luminous flux
luminous intensity measurements shall be started
after
a) 30 minutes of stabilisation time or
b) Stabilisation of temperature Tb at the value given in the relevant data sheet.
have to be carried out at relevant test
voltage.
luminous intensity of a test sample is
calculated by dividing the luminous intensity
distribution as measured under paragraph of this
annex by the luminous flux as determined after 30
minutes under paragraph of this annex.
luminous flux of a test sample is calculated
according to CIE publication 84-1989, Section by
integrating the luminous intensity within a cone
enclosing a solid angle.
3. Colour
The colour of the light emitted as measured under the same conditions as described paragraph
in of this annex shall both be within the required colour boundaries.
4. Power consumption
power consumption measurement shall be made
under the same conditions as described in paragraph
of this annex using the requirements of paragraph
of this Regulation.
consumption measurements shall be carried out
at relevant test voltage.
obtained shall comply with the minimum and
maximum requirements of the relevant data sheet.
(*1) The maximum luminous flux deviation at the tolerance limits is calculated by using the measured flux at test
voltage as reference. In between test voltage and voltage range limits the luminous flux behaviour shall be substantially
uniform.
ANNEX 5
MINIMUM REQUIREMENTS FOR QUALITY CONTROL PROCEDURES BY
THE MANUFACTURER
1. General
The conformity requirements shall be considered satisfied from a photometric, geometrical,
visual and electrical standpoint if the specified tolerances for production LED light sources in
the relevant data sheet of Annex 1 and the relevant data sheet for the caps are met.
2. Minimum requirements for verification of conformity by the manufacturer
For each type of LED light source the manufacturer or the holder of the approval mark shall
carry out tests, in accordance with the provisions of this Regulation, at appropriate intervals.
. Nature of tests
Tests of conformity of these specifications shall cover their photometric, geometrical and
optical characteristics.
. Methods used in tests
shall generally be carried out in accordance with
the methods set out in this Regulation.
application of paragraph of this annex
requires regular calibration of test apparatus and its
correlation with measurements made by a competent
authority.
. Nature of sampling
Samples of LED light sources shall be selected at random from the production of a uniform
batch. A uniform batch means a set of LED light sources of the same type, defined according to
the production methods of the manufacturer.
. Inspected and recorded characteristics
The LED light sources shall be inspected and test results recorded following the grouping of
characteristics as listed in Annex 6, Table 1.
. Criteria governing acceptability
The manufacturer or the holder of approval is responsible for carrying out a statistical study of
the test results in order to meet the specifications laid down for verification of conformity of
production in paragraph of this Regulation.
Compliance shall be assured if the level of acceptable non-compliance per grouping of
characteristics given in Table 1 of Annex 6 is not exceeded. This means that the number of
LED light sources not complying with the requirement for any grouping of characteristics of
any LED light sources type does not exceed the qualifying limits in the relevant Tables 2, 3 or
4 of Annex 6.
Note: Each individual LED light source requirement shall be considered as a characteristic.
