1. INTRODUCTION

This Annex sets out the methodology to determine the carbon dioxide (CO2) emission savings to be attributed to the use of efficient vehicle exterior LED lights in one or several of the exterior vehicle lights listed in Article 1, for use in the light commercial vehicles referred to in that Article.

2. TESTING CONDITIONS

In the case of NOVC-HEVs, the maximum available voltage level on board shall not exceed 60 Volt.

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 ), 91 ( 8 ), 100 ( 9 ), 112 ( 10 ), 119 ( 11 ) and 123 ( 12 ). 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 Table 1 of UN/ECE Regulation No 123, the power consumption measurements shall be done at the LED intensity of each class (Pk), where k corresponds to each class specified at Table 1 as defined in UN/ECE Regulation No 123.

If it is agreed with the technical service that Class C is the representative/average LED intensity for the vehicle application, power consumption measurements shall be done in the same way as for any other exterior LED light included in the combination.







Table 1 Classes of Low beam AFS Class See point 1.3 and footnote 2 of UN/ECE Regulation No 123 % LED Intensity Activation Mode (*1) C Base Passing Beam (Country) 100 50 km/h < speed < 100 km/h Or when no mode of another passing beam class is activated (V, W, E) V Town 85 Speed < 50 km/h E Motorway 110 Speed > 100 km/h W Adverse Conditions 90 Windshield wiper active > 2 minutes ( *1 ) Activation speeds shall be checked for each vehicle application in accordance with UN/ECE Regulation No 48 Section 6, Chapter 6.22, paragraphs 6.22.7.4.1 (class C), 6.22.7.4.2 (class V), 6.22.7.4.3 (class E), 6.22.7.4.4 (class W).

2.1. Test equipment

The following test equipment shall be used:

2.2. Determination of the power savings

2.2.1. Measurement of the power consumption

For each efficient exterior LED light included in a combination, the measurement of the current shall be performed 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 additional measurements of the current shall be performed at other voltages, where the necessity to do so can be demonstrated on the basis of verified documentation.

In any case the measurements (n) shall be performed for each voltage at least five times consecutively. The applied voltage and the measured current shall be recorded in four decimals.

The power consumption shall be determined by multiplying the voltage with the measured current. The average of the power consumption for each efficient exterior LED light [W] shall be calculated as set out in Formula 1 with four decimals to be taken into account in the calculations. When a stepper motor or electronic controller is used for the supply of the electricity to the LED lamps, then the electric load of this component is to be excluded from the measurement.

Formula 1

where:

is the tested voltage of each LED vehicle light i [V]

is the measured current of each LED vehicle light i [A]

n is the number of measurements of the sample

j refers to an individual measurement of power consumption

In case of low beam AFS, the power consumption [W] shall be calculated as the average of the LED power consumption for each class k, weighted according to the WLTP time share per speed range, in accordance with Formula 2.

Formula 2

where:

is the power consumption at the LED intensity for each class k as the average of n consecutive measurements [W]

K is the number of classes associated with the low beam AFS.

WLTP_share is the WLTP time share per speed range in each class as defined in Table 2.







Table 2 WLTP time share per speed range Speed range WLTP_share < 50 km/h 0,588 50 – 100 km/h 0,311 > 100 km/h 0,101

When the low beam AFS does not fall within all four classes specified in Table 1, the WLTP_share of the missing classes shall be attributed to class C.

2.2.2. Calculation of the power savings

The power savings of each efficient exterior LED light (ΔPi) [W] shall be calculated in accordance with Formula 3.

Formula 3

where:

is the power consumption of the baseline vehicle light i [W]

is the average power consumption of the eco-innovative vehicle light i [W].

The power consumption of the different baseline vehicle lights is defined in Table 3.

5. ROUNDING

The CO2 savings and the uncertainty of the CO2 savings shall be rounded to two decimal places.

Each value used in the calculation of the CO2 savings shall either be applied unrounded or be rounded to the minimum number of decimal places which allows the maximum total impact (i.e. combined impact of all rounded values) on the savings to be lower than 0,25 g CO2/km.

6. CHECK AGAINST THE MINIMUM CO2 SAVINGS THRESHOLD

The type-approval authority shall ensure for each version of a vehicle fitted with the efficient exterior LED lights that the minimum threshold criterion as specified in Article 9(1)(b) of Implementing Regulation (EU) No 427/2014 is met.

When verifying whether the minimum threshold criterion is met, the type-approval authority shall take into account, in accordance with Formula 9, the CO2 savings determined in point 3 and the uncertainty determined in point 4.
