Abstract (en)
[origin: CN115560263A] The invention relates to a light module (10) for a lighting device (2) of a vehicle (1), comprising at least one light-emitting means (19) and a light guide (24) which is suitable and defines a light exit surface (A) for guiding radiation emitted from the light-emitting means (19) and coupled into the light guide to the light guide (24), comprising at least one rear wall device (20), the at least one rear wall device (20) is arranged at least in some regions in the beam path of ambient radiation (44) incident from the outside into the light guide (24) through the light exit surface (A) of the light guide (24). According to the invention, the rear wall device (20) has at least one first rear wall region (32, 56, 67) and at least one second rear wall region (34, 57, 66), the at least one first rear wall region (32, 56, 67) and the at least one second rear wall region (34, 57, 66) differing from one another, in particular with respect to the reflection and/or absorption properties of ambient radiation (44).
