Illuminating surface definition

Illuminating surface 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. For a retro-reflector, the light-emitting surface is considered to be delimited by planes contiguous to the outermost parts of the retro-reflector’s optical system.

Illuminating surface means the orthogonal projection, in a transverse vertical plane, of the effective surface from which the light is emitted. For a reflex-reflector, the effective surface is the visible surface of the reflex-reflecting optical unit.

More Definitions of Illuminating surface

Illuminating surface means for lights, the visible surface from which light is emitted and, for reflex reflectors, the visible surface from which light is reflected.
Sample 1Sample 2
Illuminating surface means the orthogonal projection of the full aperture of the reflector, in the case of the main-beam headlamp with reflector, dipped-beam headlamp with reflector, front fog-lamp with reflector, or in the case of headlamps with an ellipsoidal reflector of the projection lens, on a transverse plane. If the light emitting surface of the lamp extends over part only of the full aperture of the reflector, the projection of that part only is taken into account.
Sample 1Sample 2Sample 3
Illuminating surface 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 in the case of rear position lamp, parking lamp, and of main-beam headlamp, dipped- beam headlamp, front fog-lamp, which are without reflector.
