6. illuminating surface (see Appendix 1)

6.1. light-emitting surface of a lighting device or retro-reflector

means all or part of the exterior surface of the translucent material as declared in the request for approval by the manufacturer of the device on the drawing (see Appendix 1);

6.2. illuminating surface of a lighting device (see points 5.7, 5.8, 5.13 and 5.15)

means the orthogonal projection of the full aperture of the reflector or in the case of headlamps with an ellipsoidal reflector of the projection lens, on a transverse plane. If the lighting device has no reflector, the definition of point 6.3 is applied. If the light-emitting surface of the lamp extends over part only of the full aperture of the reflector, then the projection of that part only is taken into account. In the case of a dipped-beam headlamp, the illuminating surface is limited by the apparent trace of the cut-off on to the lens. If the reflector and lens are adjustable relative to one another, the mean adjustment is used;

6.3. illuminating surface of a light-signalling device other than a retro-reflector (see points 5.9 to 5.12, 5.14, 5.16 and 5.17)

means the orthogonal projection of the lamp in a plane perpendicular to its axis of reference and in contact with the exterior light-emitting surface of the lamp, this projection being bounded by the edges of screens situated in this plane, each allowing only 98 % of the total luminous intensity of the light to persist in the direction of the axis of reference; to determine the lower, upper and lateral limits of the illuminating surface, only screens with horizontal or vertical edges are used;

6.4. illuminating surface of a retro-reflector (see point 5.18)

means the orthogonal projection of a retro-reflector in a plane perpendicular to its axis of reference and bounded by planes touching the outer edges of the light projection surface of the retro-reflector and parallel to this axis. To determine the lower, upper and lateral limits of the illuminating surface, only horizontal and vertical planes are used;
