Zusammenfassung:	A lens structure adapted for guiding a light from a light source to a plurality of directions is provided. The lens structure includes a base, a pillar, and an umbrella-shaped body. The base has a containing pit adapted for containing the light source. The pillar is connected to the base. The pillar has a central axis and a first curved surface, in which the first curved surface surrounds the central axis symmetrically. The umbrella-shaped body is connected to the pillar and has a second curved surface and a third curved surface surrounding the central axis symmetrically. The second and the third curved surfaces are located on a top portion of the umbrella-shaped body and next to each other.
