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.
