Abstract
An arrangement (10) for generating a light effect (26) includes an obscuration sheet material (11) and a divergence sheet material (12) arranged in spaced apart relation to a rear side (23) of an effect sheet material (13). The obscuration sheet material (11) has at least one transmission region (17) and at least one shielding region (18). On the light entry side (15), which faces away from the effect sheet material (13), light (L) impinges on the obscuration sheet material (11) and is severely reduced or completely shielded in shielding region (18), while light (L) passes through the at least one transmission region (17). By means of the divergence sheet material (12), divergent light rays (LD) are produced at the corresponding transmission region (17), which divergent light rays impinge on the rear side (23) of the effect sheet material (13) and generate a light effect (26) for a viewer (25) looking at the viewing side (24).
