Zusammenfassung:	A light guide element and a lighting fixture are described. The light guide element includes a light guide body, a plurality of first microstructures and a plurality of second microstructures. The light guide body includes a first light-emitting surface and a second light-emitting surface opposite to and parallel to each other. The first microstructures are disposed on the first light-emitting surface. The second microstructures are respectively corresponding to the first microstructures, in which the second microstructures are disposed on the second light-emitting surface. In a normal direction of the first light-emitting surface, each first microstructure laps over the corresponding second microstructure in part. The first microstructures and the second microstructures have the same size but different pitches.
