2.8"Light emitting surface" of a "lighting device", "light-signaling device" or a
retro reflector means the surface as declared in the request for approval by
the manufacturer of the device on the drawing, see Annex 3
透光面是指制造商在提交型式检验申请书所附的图纸中标出的装置表面
This shall be declared according to one of the following conditions:
它应依照以下的条件标出
(a) In the case where the outer lens is textured, the declared light emitting surface
shall be all or part of the exterior surface of the outer lens;
在外透镜有纹理的情况下，透光面是外透镜的全部或部分表面
(b) In the case where the outer lens is non-textured the outer lens may be
disregarded and the light emitting surface shall be as declared on the
drawing, see Annex 3;
在外透镜无纹理的情况下，外透镜可能忽视，透光面将在图纸中标出
在外透镜无纹理的情况下外透镜可能忽视透光面将在图纸中`

2.1    ‘Illuminating surface’ defined in 2.9.1
发光面
2.9.1"Illuminating surface”of a lighting device(driving beam,passing beam,front
fog lamp,reversing lamp and cornering lamp)means the orthogonal
projection of the full aperture of the reflector,or in the case of headlamps with
"projection lens"plane an ellipsoidal reflector of the projection lens,on a transverse plane.If the
lighting device has no reflector,the definition of paragraph2.9.2.shall be
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.

镜在一横截面上的垂直投影.若照明装置不带反射镜，则适用2.9.2定义.若灯具的透光面
只占据反射镜口径的部分，则只考虑该部分的投影。
只占据反射镜口径的一部分
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 should be used;

对于近光灯，发光面受到明暗截止线在配光镜上视在图样的限制.若反射镜和配光镜可
以调节，则应处在平均调节位子上。
2.1    ‘Illuminating surface’ defined in 2.9.1
发光面
In case an AFS is installed:where a lighting function is produced by two or
more simultaneously operated lighting units on a given side of the vehicle,the
individual illuminating surfaces,taken together,constitute the illuminating
surface to be considered(for example,in the figure of paragraph6.22.4.below,
example6224below the individual illuminating surfaces of the lighting units8,9and11,regarded
together and taking into account their respective location,constitute the
illuminating surface to be considered for the right hand side of the vehicle).
对于自适应前照明系统：当照明功能是由两个或多个同时操作的照明单元，要考虑由
个别发光面组成的发光面。
