Abstract: An optical lens structure includes a main body portion and a projection portion. One side of the main body portion is recessed to form an opening and a light incident portion corresponding to the opening. The main body portion has a plurality of first reflection sides and a plurality of second reflection sides arranged opposite to the plurality of first reflection sides. Each of the plurality of second reflection sides is recessed to form a recessed portion. The projection portion arranged on the other side of the main body portion. One side of the projection portion faced away from the main body portion is recessed to form a through opening and a light emitting portion. The light incident portion receives and refracts a plurality of external light beams, so that one part of the plurality of external light beams is projected to the light emitting portion.

Abstract: A variable focus lighting fixture includes a fixed sleeve assembly, a moveable sleeve assembly, a light emitting unit, a lens and an actuation assembly. The moveable sleeve assembly penetrates into the fixed sleeve assembly and moves relative to the fixed sleeve assembly. The light emitting unit is secured onto the fixed sleeve assembly. The lens is secured onto the moveable sleeve assembly. The actuation assembly is connected between the moveable sleeve assembly and the fixed sleeve assembly. The actuation assembly includes a spiral curve slot and a sliding pin penetrating into the spiral curve slot. When the moveable sleeve assembly rotates along a central axis of the moveable sleeve assembly, the sliding pin moves along the spiral curve slot to drive the moveable sleeve assembly to move along the axial direction thereof. Accordingly, the projection path of the light from the light emitting unit through the lens is altered.
