Bend lighting may be produced by activating one additional filament light source or one or more LED module(s) being part of the passing-beam headlamp. a0c0
6.1.2. The luminous intensity produced by the headlamp shall be measured at 25 m distance by means of a photoelectric cell having a useful area comprised within a square of 65 mm side. The point HV is the centre-point of the coordinate system with a vertical polar axis. Line h is the horizontal through HV (see Annex 3 to this Regulation). a0c0
6.1.3. Apart from LED module(s), the headlamps shall be checked by means of an uncoloured standard (étalon) filament lamp designed for a rated voltage of 12 V. a0c0
6.1.3.1. During the checking of the headlamp, the voltage at the terminals of the filament lamp shall be regulated as to obtain the reference luminous flux at 13.2 V as indicated for each filament lamp at the relevant data sheet of Regulation No. 37. a0c0
... However, if a filament lamp of category H9 or H9B is used for the principal passing-beam, the applicant may choose the reference luminous flux at 12.2 V or 13.2 V as indicated in the relevant data sheet of Regulation No. 37 and a reference stating which voltage was chosen for type approval shall be made in item 9 in the communication form of Annex 1. a0c0
6.1.3.2. In order to protect the standard (étalon) filament lamp during the process of photometric measurement it is permissible to carry out the measurements at a luminous flux that differs from the reference luminous flux at 13.2 V. If the Technical Service chooses to carry out measurements in such a manner, the luminous intensity shall be corrected by multiplying the measured value by the individual factor F lamp of the standard (étalon) filament lamp in order to verify the compliance with the photometric requirements where: a0c0
... F lamp = Φ reference / Φ test a0c0
... Φ reference is the reference luminous flux at 13,2 V as specified in the relevant data sheet of Regulation No. 37 a0c0
... Φ test is the actual luminous flux used for the measurement. a0c0
... However, where the reference luminous flux of 12.2 V as specified in the data sheet for the category H9 or H9B is chosen, this procedure is not permitted. a0c0
6.1.3.3. The headlamp shall be considered acceptable if it meets the requirements of paragraph 6. with at least one standard (étalon) filament lamp, which may be submitted with the headlamp. a0c0
6.1.4. LED module(s) shall be measured at 6.3 V, 13.2 V or 28.0 V respectively, if not otherwise specified within this Regulation. LED module(s) operated by an electronic light source control gear, shall be measured as specified by the applicant. a0c0
6.1.5. In the case of headlamps equipped with LED module(s) and filament lamps, the part of the headlamp with filament lamp(s) shall be tested according to paragraph 6.1.3. and the part of the headlamp with LED module(s) shall be evaluated according to the provisions of paragraph 6.1.4. and then added to the previous result obtained from the filament lamp(s) tested. a0c0
6.2. Provisions concerning passing-beams a0c0
6.2.1. The luminous intensity distribution of the principal passing-beam headlamp shall incorporate a "cut-off" (see Figure 1), which enables the headlamp to be adjusted correctly for the photometric measurements and for the aiming on the vehicle. a0c0
... The "cut-off" shall provide: a0c0
... (a)For right hand traffic beams: a0c0
... (i)A straight "horizontal part" towards the left; a0c0
... (ii)A raised "elbow - shoulder" part towards the right. a0c0
... (b)For left hand traffic beams: a0c0
... (i)A straight "horizontal part" towards the right; a0c0
... (ii)A raised "elbow - shoulder" part towards the left. a0c0
... In each case the "elbow-shoulder" part shall have a sharp edge. a0c0
6.2.2. The headlamp shall be visually aimed by means of the "cut-off" (see Figure 1) as follows. The aiming shall be carried out using a flat vertical screen set up at a distance of 10 m or 25 m (as indicated in item 9 of Annex 1) forward of the headlamp and at right angles to the H-V axis as shown in Annex 3 to this Regulation. The screen shall be sufficiently wide to allow examination and adjustment of the "cut-off" of the passing-beam over at least 5° on either side of the V-V line. a0c0
6.2.2.1. For vertical adjustment: the horizontal part of the "cut-off" is moved upward from below line B and adjusted to its nominal position one per cent (0.57 degrees) below the H-H line; a0c0
... Figure 1 a0c0
... a0c0
... Note: The scales are different for vertical and horizontal lines. a0c0
6.2.2.2. For horizontal adjustment: the "elbow – shoulder" part of the "cut-off" shall be moved: a0c0
... For right hand traffic from right to left and shall be horizontally positioned after its movement so that: a0c0
... (a)Above the line 0.2° D its "shoulder" shall not exceed the line A to the left; a0c0
... (b)The line 0.2° D or below its "shoulder" should cross the line A; and a0c0
... (c)The kink of the "elbow" is basically located within +/-0.5 degrees to the left or right of the V-V line; a0c0
... or a0c0
... For left hand traffic from left to right and shall be horizontally positioned after its movement so that: a0c0
... (a)Above the line 0.2 D its "shoulder" shall not exceed the line A to the right; a0c0
... (b)On the line 0.2° or below its "shoulder" cross the line A; and a0c0
... (c)The kink of the "elbow" should be primarily on the V-V line; a0c0
6.2.2.3. Where a headlamp so aimed does not meet the requirements set out in paragraphs 6.2.4. to 6.2.6. and 6.3., its alignment may be changed, provided that the axis of the beam is not displaced: a0c0
... Horizontally from line A by more than: a0c0
... (a)0.5° to the left or 0.75° to the right, for right hand traffic; or a0c0
... (b)0.5° to the right or 0.75° to the left, for left hand traffic; and a0c0
... Vertically not more than 0.25° up or down from line B. a0c0
6.2.2.4. If, however, vertical adjustment cannot be performed repeatedly to the required position within the tolerances described in paragraph 6.2.2.3. above, the instrumental method of Annex 9, paragraphs 2. and 3. shall be applied to test compliance with the required minimum quality of the "cut-off" and to perform the vertical and horizontal adjustment of the beam. a0c0
6.2.3. When so aimed, the headlamp, if its approval is sought solely for provision of a passing-beam[8], need comply only with the requirements set out in paragraphs 6.2.4. to 6.2.6. below; if it is intended to provide both a passing-beam and a driving-beam, it shall comply with the requirements set out in paragraphs 6.2.4. to 6.2.6. and 6.3. a0c0
[8] Such a special "passing-beam" headlamp may incorporate a driving-beam not subject to requirements. a0c0
6.2.4. The passing-beam shall meet the luminous intensities at the test points referred to in the tables below and in Annex 3 Figure B (or mirrored about the VV line for left-hand traffic): a0c0
... a0c0
... a0c0
... a0c0
6.2.5. There shall be no lateral variations detrimental to good visibility in any of the zones I, II, III and IV. a0c0
6.2.6. Headlamps designed to meet the requirements of both right-hand and left-hand traffic must, in each of the two setting positions of the optical unit or LED module(s) producing the principal passing-beam or of the filament lamp, meet the requirements set forth above for the corresponding direction of traffic. a0c0
6.2.7. The requirements in paragraph 6.2.4. above shall also apply to headlamps designed to provide bend lighting and/or that include the additional light source or LED module(s) referred to in paragraph 6.2.8.2. In the case of a headlamp designed to provide bend lighting its alignment may be changed, provided that the axis of the beam is not displaced vertically by more than 0.2°. a0c0
6.2.7.1. If bend lighting is obtained by: a0c0
6.2.7.1.1. Swivelling the passing-beam or moving horizontally the kink of the elbow of the cut-off, the measurements shall be carried out after the complete headlamp assembly has been reaimed horizontally, e.g. by means of a goniometer; a0c0
6.2.7.1.2. Moving one or more optical parts of the headlamp without moving horizontally the kink of the elbow of the cut-off, measurements shall be carried out with these parts being in their extreme operating position; a0c0
6.2.7.1.3. Means of one additional filament light source or one or more LED module(s) without moving horizontally the kink of the elbow of the cut-off, measurements shall be carried out with this light source or LED module(s) activated. a0c0
6.2.8. Only one filament light source or one or more LED module(s) are permitted for the principal passing-beam. Additional light sources or LED modules are permitted only as follows (see Annex 10): a0c0
6.2.8.1. One additional light source according to Regulation No. 37 or one or more additional LED module(s) may be used inside the passing-beam headlamp to contribute to bend lighting; a0c0
6.2.8.2. One additional light source according to Regulation No. 37 and/or one or more LED module(s), inside the passing-beam headlamp, may be used for the purposes of generating infrared radiation. It/they shall only be activated at the same time as the principal light source or LED module(s). In the event that the principal light source or (one of) the principal LED module(s) fails, this additional light source and/or LED module(s) shall be automatically switched off; a0c0
6.2.8.3. In the event of failure of an additional filament light source or one or more additional LED module(s), the headlamp shall continue to fulfil the requirements of the passing-beam. a0c0
6.3. Provisions concerning driving-beams a0c0
6.3.1. In the case of a headlamp designed to provide a driving-beam and a passing-beam, measurements of the luminous intensity of the driving-beam shall be taken with the same headlamp alignment as for measurements under paragraphs 6.2.4. to 6.2.6. above; in the case of a headlamp providing a driving-beam only, it shall be so adjusted that the area of maximum luminous intensity is centred on the point of intersection of lines H-H and V-V; such a headlamp need meet only the requirements referred to in paragraph 6.3. Where more than one light source is used to provide the driving-beam, the combined functions shall be used to determine the maximum value of the luminous intensity (IM). a0c0
6.3.2. Irrespective of the type of light source (LED module(s) or filament light source(s)) used to produce the principal passing-beam, several light sources: a0c0
... (a)Either filament light sources listed in Regulation No. 37; or a0c0
... (b)LED module(s) may be used for each individual driving-beam. a0c0
6.3.3. Referring to Annex 3, Figure C and the table below, the luminous intensity distribution of the driving-beam shall meet the following requirements: a0c0
... a0c0
6.3.3.1. The point of intersection (HV) of lines h h and v v shall be situated within the isolux 80 per cent of maximum luminous intensity (Imax) a0c0
6.3.3.2. The maximum value (IM) shall in no circumstances exceed 215,000 cd. a0c0
6.3.4. The reference mark (I'M) of the maximum luminous intensity, referred to in paragraph 6.3.3.2. above, shall be obtained by the ratio: a0c0
... I'M = IM /4,300 a0c0
... This value shall be rounded off to the value 7.5 - 10 - 12.5 - 17.5 - 20 - 25 - 27.5 - 30 - 37.5 - 40 - 45 - 50. a0c0
6.4. In the case of headlamps with adjustable reflector the requirements of paragraphs 6.2. and 6.3. are applicable for each mounting position indicated according to paragraph 2.1.3. For verification the following procedure shall be used: a0c0
6.4.1. Each applied position is realized on the test goniometer with respect to a line joining the centre of the light source and point HV on a aiming screen. The adjustable reflector is then moved into such a position that the light pattern on the screen corresponds to the aiming prescriptions of paragraphs 6.2.1. to 6.2.2.3. and/or 6.3.1.; a0c0
6.4.2. With the reflector initially fixed according to paragraph 6.4.1., the headlamp must meet the relevant photometric requirements of paragraphs 6.2. and 6.3.; a0c0
6.4.3. Additional tests are made after the reflector has been moved vertically ±2° or at least into the maximum position, if less than 2°, from its initial position by means of the headlamps adjusting device. Having re-aimed the headlamp as a whole (by means of the goniometer for example) in the corresponding opposite direction the light output in the following directions shall be controlled and lie within the required limits: a4c0
