INTRODUCTION

This Regulation(1) applies to front fog lamps, which may incorporate lenses of glass or plastic material. It incorporates two distinct classes.

The original front fog lamp, class ‘B’ since inception, has been updated to incorporate the angular coordinate system with an amendment to the values in the relevant photometric table. With this class, only light sources as specified in Regulation No 37 are allowed.

The class ‘F3’ is designed to increase photometric performance. In particular the beam width and the minimum luminous intensities below the H-H line (paragraph 6.4.3) have been increased whilst controls on the maximum intensity in the foreground are introduced. Above the H-H line, the intensity of the veiling light is reduced to improve visibility. Additionally this class may provide adaptive beam patterns where the performance is varied according to the visibility conditions.

The introduction of the class ‘F3’ provides for requirements that are amended to be similar to those of a headlamp as follows:

(a) The photometric values are specified as luminous intensities using the angular coordinate system.

(b) Light sources can be selected according to the provisions of Regulation No 37 (Incandescent filament light sources) and Regulation No 99 (gas discharge light sources). Light emitting diode (LED) modules and distributed lighting systems may also be used.

The cut-off and the gradient definitions.

The photometric requirements permit the use of asymmetrical beam distributions.

The correct position of the lens shall be clearly marked and the lens and reflector shall be so secured as to prevent any rotation during use. Conformity with the requirements of this paragraph shall be verified by visual inspection and, where necessary, by a trial fitting.

5.2.1. Front fog lamps shall be fitted with a device enabling them to be so adjusted on the vehicles as to comply with the rules applicable to them.

5.7.2.

And/or, one or more LED modules where the requirements of Annex 12 to this Regulation shall apply; compliance with these requirements shall be tested.

5.7.3.

And/or light-generators where the requirements of Annex 12 to this Regulation shall apply. The compliance with the requirements shall be tested.

ANNEX 9

DEFINITION AND SHARPNESS OF THE CUT-OFF LINE AND AIMING PROCEDURE BY MEANS OF THIS CUT-OFF LINE FOR CLASS ‘F3’ FRONT FOG LAMPS

1. GENERAL

The luminous intensity distribution of the front fog lamp shall incorporate a cut-off line that enables the front fog lamp to be adjusted correctly for the photometric measurements and for the aiming on the vehicle. The characteristics of the cut-off line shall comply with the requirements set out in paragraphs 2 to 4.

For visual adjustment of the front fog beam the cut-off line shall provide: a horizontal line for vertical adjustment of the front fog lamp extending to 4° either side of the v-v line (see Figure 1).

Figure 1

Shape and position of the ‘cut-off’ line

[Bild bitte in Originalquelle ansehen]

3. ADJUSTMENT OF THE FRONT FOG LAMP

3.1. Horizontal adjustment

The cut-off line shall be so positioned that the projected beam pattern appears approximately symmetrical to the v-v line. When the front fog lamp is designed for use in pairs or has otherwise an asymmetric beam pattern, it shall be horizontally aligned according to the specification of the applicant, or otherwise in such a way that the cut-off line appears symmetrical to the v-v line.

3.2. Vertical adjustment

After horizontal adjustment of the front fog beam according to paragraph 3.1, the vertical adjustment shall be performed in such a way that the cut-off line is moved upwards from the lower position until it is situated on the v-v line at 1° below the h-h line. If the horizontal part is not straight but slightly curved or inclined, the cut-off line shall not exceed the vertical range formed by two horizontal lines which are situated between 3° left and right of the v-v line at 0,2° above and below the nominal position of the cut-off (see Figure 1).

3.2.1.

When the vertical positions of three attempts to adjust the cut-off differ by more than 0,2°, the horizontal part of the cut-off line is assumed not to provide sufficient linearity or sharpness for performing visual adjustment. In this case the quality of cut-off shall be tested instrumentally for compliance with requirements as follows.

4. MEASUREMENT OF THE QUALITY OF CUT-OFF

4.1. Measurements shall be performed by vertically scanning through the horizontal part of the cut-off line in angular steps not exceeding 0,05°.

At either a measurement distance of 10 m and a detector with a diameter of approximately 10 mm.

Or at a measurement distance of 25 m and a detector with a diameter of approximately 30 mm.

The measurement of the cut-off quality shall be considered acceptable if the requirements of the paragraphs 4.1.1 to 4.1.3 of this annex shall comply with at least one measurement at 10 m or 25 m.

The measuring distance at which the test was determined shall be recorded in paragraph 9 of the communication form in Annex 2 of this Regulation.

The scanning is performed from downwards upwards through the cut-off line along the vertical lines at – 2,5° and + 2,5° from the v-v line. When so measured, the quality of the cut-off line shall meet the following requirements:

4.1.1. Not more than one cut-off line shall be visible.

4.1.2. Sharpness of cut-off:

If scanned vertically through the horizontal part of the cut-off line along vertical lines at ± 1° from the v-v line, the maximum value measured for the sharpness factor G of the cut-off line shall not be less than 0,08 where:

[Bild bitte in Originalquelle ansehen]

4.1.3. Linearity

The part of the cut-off line which serves vertical adjustment shall be horizontal from 3° left to 3° right of the v-v line. This requirement is satisfied, if the vertical positions of the inflection points according to paragraph 3.2 at 3° left and right of the v-v line do not deviate by more than ± 0,20°.

5. INSTRUMENTAL VERTICAL ADJUSTMENT

If the cut-off line complies with the above quality requirements, the vertical beam adjustment can be performed instrumentally. For this purpose the inflection point where d

(log E)/dv

= 0 is positioned on the v-v line and below the h-h line. The movement for measuring and adjusting the cut-off line shall be upwards from below the nominal position.
