Zusammenfassung:This invention discloses a light-adjusting device comprising a light guide assembly and an angle adjusting assembly. The light guide assembly includes a first light guide group and a second light guide group. The angle adjusting assembly is arranged between the first light guide group and the second light guide group and is composed of at least one angle-adjusting component, the angle adjusting component includes a first micro-structural layer, and the first light guide group is used for guiding at least one part of a light beam to the angle adjusting component, so that the at least one part of the light beam is refracted to be in different advancing directions after passing through the first micro-structural layer and is then emitted from the second light guide group. Therefore, a plurality of light beams in the different advancing directions can be adjusted.
