Embodiment Construction
[0013] Referring to the accompanying drawings, it is a lens matched with a high-power LED lamp. The lens structure includes a lens unit 1 matched with the basic light-emitting unit of the LED lamp. The above-mentioned lens unit 1 is composed of a cylindrical convex lens 1-1 and two symmetrical A composite structure composed of spherical convex lenses 1-2 and 1-3 distributed on both sides of the cylindrical convex lens 1-1.
[0014] The spherical centers of the above two spherical convex lenses 1-2, 1-3 are arranged symmetrically on the mid-perpendicular of the axis of the cylindrical convex lens 1-1.
[0015] The inner surface of the above-mentioned cylindrical convex lens 1-1 is an arc cylindrical structure, and the outer surface is an arc spherical structure. The intersecting lines form a composite light emitting surface.
[0016] The spherical convex lenses 1-2 and 1-3 mentioned above are entities of a partial sphere whose outer surface is a spherical surface.
