3. TESTING CONDITIONS

The testing conditions shall fulfil the requirements of UN/ECE Regulations Nos 4 ( 1 ), 6 ( 2 ), 7 ( 3 ), 19 ( 4 ), 23 ( 5 ), 38 ( 6 ), 48 ( 7 ), 100 ( 8 ), 112 ( 9 ), 119 ( 10 ) and 123 ( 11 ). The power consumption shall be determined in accordance with point 6.1.4 of UN/ECE Regulation No 112, and points 3.2.1 and 3.2.2 of Annex 10 to that Regulation.

For the low beam adaptive front lighting system (AFS) falling within at least two of the Classes C, E, V or W as defined in Regulation UN/ECE No 123, unless it is agreed with the technical service that Class C is the representative/average LED intensity for the vehicle application, power measurements shall be done at the LED intensity of each class (Pc) as defined in Regulation UN/ECE 123. If Class C is the representative/average LED intensity for the vehicle application, power measurements shall be done in the same way as for any other exterior LED light included in the combination.

Test equipment

The following equipment shall be used, as shown in the Figure below:

— a power supply unit (i.e. variable voltage supplier);

— two digital multimeters, one for measuring the DC-current, and the other for measuring the DC-voltage. In the Figure, a possible test set-up is shown, when the DC-voltage meter is integrated in the power supply unit.

Test set-up

Measurements and determination of the power savings

For each efficient exterior LED light included in the combination the measurement of the current shall be performed as shown in the Figure at a voltage of 13,2 V. LED module(s) operated by an electronic light source control gear, shall be measured as specified by the applicant.

The manufacturer may request that other measurements of the current shall be done at other additional voltages. In that case, the manufacturer shall hand over verified documentation on the necessity to perform those other measurements to the type-approval authority. The measurements of the currents at each of those additional voltages shall be performed consecutively at least five times. The exact installed voltages and the measured current shall be recorded in four decimals.

The power consumption shall be determined by multiplying the installed voltage with the measured current. The average of the power consumption for each efficient exterior LED light (

) shall be calculated. Each value shall be expressed in four decimals. When a stepper motor or electronic controller is used for the supply of the electricity to the LED lights, the electric load of that component part shall be excluded from the measurement.

Additional measurements for Low beam Adaptive Front Lighting System (AFS)

Where the power measurements at the LED intensity of each class are needed, after conducting the measurements of each Pc, the power of the Low beam AFS (

) shall be calculated as a weighted average of the LED Power during the WLTC speed bands, with the following Formula 1.

Formula 1

Where:

is the power consumption (mean of the n measurements) for each class; is the power consumption (mean of the n measurements) for each class;

is the WLTC time percentage per speed band in each class (WLTC last 1 800 s in total): is the WLTC time percentage per speed band in each class (WLTC last 1 800 s in total):







Table 2 Speed band Time WLTC_sharec (%) < 50 km/h: 1 058 s 0,588 (58,8 %) 50 – 100 km/h 560 s 0,311 (31,1 %) > 100 km/h 182 s 0,101 (10,1 %)

When the Low beam AFS only has 2 classes not covering all WLTC speeds (e.g. C & V), the weighting of Class C power shall also include the WLTC time not covered by the 2nd class (e.g. Class C time ‘t’ = 0,588 + 0,101)

The resulting power savings of each efficient exterior LED light (ΔPi) shall be calculated with the following Formula 2:

Formula 2

where the power consumption of the corresponding baseline vehicle light is as specified in Table 3:
