category which differ in such essential respects as:
2.1.2.1. Trade name or mark;
LED light sources bearing the same trade name or mark but produced by
different manufacturers are considered as being of different types. LED light
sources produced by the same manufacturer differing only by the trade name

In case of LED light source failure (no light emitted) the maximum current draw – when
operated within the input voltage range in major function mode – operation shall be less
than 20 mA (open circuit condition).
Screen projection requirements
The following test is intended to define the requirements for the apparent light emitting area
of the LED light source and to determine whether the light emitting area is correctly
positioned relative to the reference axis and reference plane in order to check compliance
with the requirements.
The position of the light emitting area is checked by the box system defined in Figure 3,
which shows the projections when viewing along direction =90º in the planes C90 and C180
(C,  as defined in Figure 4). At least 95 per cent of the luminous flux emitted into the
viewing direction has to come from the trapezoidal area defined by d1, d2 and c. Less than
70 per cent of the luminous flux shall be emitted from the rectangular area defined by d3
and c.

Normalized luminous intensity distribution

The following test is intended to determine the normalized luminous intensity distribution
of the light source in an arbitrary plane containing the reference axis. The intersection of
the reference axis and the upper edge of the box is used as the coordinate system origin.
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, so that the reference axis of the
light source lines up with one of the rotating axis of the goniometer. The corresponding
measurement set-up is described in Figure 4.

Luminous intensity data is recorded for the major function with a standard photo-

the detector is located in the far field of the light distribution.
The measurements shall be performed in 3 C-planes, which contain the reference axis of the
light source. The 3 C-planes shall be within C30 and C330 to avoid the connector shadows
and they have to be at least 30º apart from each other. The test points for each plane for
multiple polar angles  are specified in Table 3.
After measurement the data shall be normalized to 1000 lm according to paragraph 3.1.11
using the luminous flux of the individual light source under test. The data shall comply with
the tolerance band as defined in Table 3.

Annex 3

Example of the arrangement of the approval mark

(see paragraph 2.4.4.)

The above approval mark affixed to a LED light source indicates that the light
source has been approved in the United Kingdom (E11) under the approval code 0A1. The
first character of the approval code indicates that the approval was granted in accordance
with the requirements of Regulation No. 128* in its original form.

* Not requiring changes in the approval number.

Annex 4

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 T b shall be measured by
stabilising the Tb-point at the specific temperature defined on the category data sheet.
1. Luminous flux
1.1. A 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.
1.2. The 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.
1.3. Measurements 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.
Rated voltage Min voltage Max voltage
6 6.0 7.0
12 12.0 14.0
24 24.0 28.0
Corresponding luminous flux
±30% ±15%
tolerance*
* 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.
2. Normalized luminous intensity
2.1. The luminous intensity measurements shall be started after
a) 30 minutes of stabilization time or
b) Stabilisation of temperature Tb at the value given in the relevant data
sheet.

E/ECE/TRANS/505/Rev.2/Add.126
Annex 4
2.2. Measurements have to be carried out at relevant test voltage.
2.3 Normalized luminous intensity of a test sample is calculated by dividing the
luminous intensity distribution as measured under paragraph 2.1. of this
annex by the luminous flux as determined after 30 minutes under
paragraph 1.2. of this annex.
3. Colour
The colour of the light emitted as measured under the same conditions as
described paragraph in 1.1. of this annex shall both be within the required
colour boundaries.
4. Power consumption
4.1 A power consumption measurement shall be made under the same conditions
as described in paragraph 1.1 of this annex using the requirements of
paragraph 3.3.3. of this Regulation.
4.2 Power consumption measurements shall be carried out at relevant test
voltage.
4.3 Values obtained shall comply with the minimum and maximum requirements
of the relevant data sheet.

Annex 5

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.
2.1. Nature of tests
Tests of conformity of these specifications shall cover their photometric,
geometrical and optical characteristics.
2.2. Methods used in tests
2.2.1. Tests shall generally be carried out in accordance with the methods set out in
this Regulation.
2.2.2. The application of paragraph 2.2.1. of this annex requires regular calibration
of test apparatus and its correlation with measurements made by a competent
authority.
2.3. 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.
2.4. 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.
2.5. 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 4.1. 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.

colour and luminous flux) applies to each element separately.
