ANNEX 4

METHOD OF MEASUREMENT OF ELECTRICAL AND PHOTOMETRICAL CHARACTERISTICS

LED 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 air space as defined in the data sheets shall be maintained.

LED 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.

In case a maximum test temperature is specified in the relevant data sheet of Annex 1 additional measurements shall be carried out at elevated temperatures according to the method described in paragraph 5 of this annex.

1.   LUMINOUS FLUX

(b)

in case of a Tb point, specified in the relevant data sheet, after stabilisation of the temperature at this Tb point.

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 and 2.2 of this annex by the luminous flux as determined under paragraph 1.2 of this annex.

2.4.   Cumulative luminous flux of a test sample is calculated according to CIE publication 84-1989, Section 4.3 by integrating the luminous intensity values as measured under 2.1 and 2.2 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 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.

5.   PHOTOMETRIC MEASUREMENTS IN CASE A MAXIMUM TEST TEMPERATURE IS SPECIFIED

5.1.   Temperature and temperature range

5.1.1.   Photometric measurements as specified in paragraphs 5.3, 5.4 and 5.5 shall be carried out at elevated temperatures T in steps not larger than 25 °C, while the LED light source is continuously operated.

5.1.1.1.   In case of LED light sources of a category with integrated heatsink the temperature range is defined by the ambient temperature of (23 ± 2) °C elevated up to and including the maximum test temperature as specified in the relevant data sheet of Annex 1, whereas the minimum free air space as defined in the relevant data sheet shall be maintained and a period of 30 minutes of operation shall be awaited after each increase of the ambient temperature.

5.1.1.2.   In case of LED light sources of a category, for which a temperature Tb is specified, the temperature range is defined by the temperature Tb specified in the relevant data sheet elevated up to and including the maximum test temperature as specified in the relevant data sheet of Annex 1, whereas the temperature at the Tb-point is stabilised before each measurement.

5.2.   Voltage

Measurements shall be carried out at relevant test voltage.

5.3.   Measurement direction of luminous intensity and colour coordinates

All the values of luminous intensity and the colour coordinates in the temperature range as specified by paragraph 5.1 may be measured in one and the same direction. This direction shall be such that the luminous intensity is exceeding 20 cd for all measurements.

5.4.   Luminous flux values at elevated temperatures

The values of the luminous flux at elevated temperatures T in the range as specified by paragraph 5.1 may be calculated by correcting the value of the luminous flux as measured according to paragraph 1.2 of this annex, by the ratio of the luminous intensity values as described in paragraph 5.3 and the luminous intensity value measured at:

| (a) | 23 °C, in case of an integrated heatsink; |
| --- | --- |

5.5.   Colour variation

The colour variation is the maximum deviation of all colour points (given by the chromaticity coordinates x, y) at elevated temperatures T in the range as specified by paragraph 5.1, from the colour point (x0, y0) at:

| (a) | 23 °C, in case of an integrated heatsink:
  max{√[(x(T) – x0(23 °C))2 + (y(T) – y0(23 °C))2]}; |
| --- | --- |

(a)

23 °C, in case of an integrated heatsink:

max{√[(x(T) – x0(23 °C))2 + (y(T) – y0(23 °C))2]};

| (b) | Tb, in case a temperature value Tb is defined:
  max{√[(x(T) – x0(Tb))2 + (y(T) – y0(Tb))2]}. |
| --- | --- |

(b)

Tb, in case a temperature value Tb is defined:

max{√[(x(T) – x0(Tb))2 + (y(T) – y0(Tb))2]}.

---

(*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.

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.

(1)  The proposed scheme is designed to assess the compliance of LED light sources to an acceptance level of non-compliance of 1 per cent and 6,5 per cent respectively and is based on the Double Sampling Plan for Normal Inspection in IEC Publication 60410: Sampling Plans and Procedures for Inspection by Attributes.

(*1)  The LED light sources shall be inspected and test results recorded following the grouping of characteristics as listed in Annex 6, Table 1.

ANNEX 9

METHOD FOR THE MEASUREMENT OF LUMINANCE CONTRAST AND LUMINANCE UNIFORMITY OF THE LIGHT EMITTING AREA

1.   The luminance measurement equipment shall be capable to distinguish clearly whether the luminance contrast of the light emitting area is above or below the required level for the LED light source under test.

Further, this equipment shall have a resolution of 20 μm or smaller in an area that is larger than the light emitting area of the LED light source under test. In case this equipment has a resolution of less than 10 μm, adjacent luminance measurement values shall be arithmetically averaged so as to represent a luminance value of an area of between 10 μm and 20 μm.

2.   The luminance measurements of an area shall be done in an equidistant grid in both directions.

3.   Zone 1a and zone 1b shall be determined from luminance measurements of an area which consists of the nominal emitter box as specified in the relevant data sheet of Annex 1 and enlarged to all sides by 10 per cent of the corresponding box dimension (see figure 1). The value L98 is the 98th percentile of all values of these luminance measurements.

3.1.   Zone 1a (light emitting area) shall be the smallest circumferential rectangle having the same orientation as the nominal emitter box and containing all luminance measurements with a value of 10 per cent or more of the value L98. The value L1 shall be the arithmetic average of the values of all luminance measurements in zone 1a (see figure 2). The value of R0,1 shall be the surface ratio of zone 1a where the luminance value is exceeding 10 per cent of the value L1. The value of R0,7 shall be the surface ratio of zone 1a where the luminance value is exceeding 70 per cent of the value L1.

3.2.   Zone 1b shall be the smallest circumferential rectangle having the same orientation as the nominal emitter box and containing all luminance measurements with a value of 70 per cent or more of the value L98.

4.   Zone 2 shall have in both directions 1,5 times the size of the nominal emitter box as specified in the relevant data sheet of Annex 1 and it shall be positioned symmetrically to the nominal emitter box at a distance of d0 = 0,2 mm to zone 1a, unless otherwise specified on the data sheet (see figure 3). The value L2 shall be the arithmetic average of 1 per cent of all measured luminance values in zone 2 which represent the highest values.

In case in the relevant data sheet more than one side of zone 1a (light emitting area) is specified as to generate the cut-off, for each of these sides a value L2 shall be determined as described above.

5.   The luminance contrast value(s) shall be the ratio of the luminance value L1 of zone 1a and the luminance value L2 of zone(s) 2.

6.   In case the nominal emitter box as specified in the relevant data sheet of Annex 1 is subdivided in n areas (e.g. n = 1 × 4), the same subdivision shall also apply to zone 1a.

6.1.   For each of the n areas the value L1,i (i = 1, ..., n) shall be the arithmetic average of the values of all luminance measurements in the corresponding area.

6.2.   The value ΔL shall be the maximum relative deviation of all luminance values L1,i from the luminance value L1.

ΔL = Max {(L1,i – L1)/L1; i = 1, ..., n}
