Abstract: A lens structure formed by materials in different refractive indexes includes a sphere, a first lens and a separation layer which is disposed between the sphere and the first lens. The sphere and the first lens have a different refractive index and the sphere is a round ball. The first lens is formed on the sphere that part of the sphere is exposed out of the first lens, and the first lens includes a first light absorption curve. The separation layer includes a transparent section opposite to the first light absorption curve. When a light beam passes through the second portion of the sphere to form a first light condensing effect and enter the sphere, the light beam will then pass through the transparent section to enter the first lens, forming a second light condensing effect after passing through the first light absorption curve.

Abstract: The present invention discloses a Fresnel lens with better reflection area and refraction area. The Fresnel lens includes a converging surface and an incidence surface opposite to the converging surface. The incidence surface is provided with an optically effective refractive region and an optically reflective region annularly surrounding the optically effective refractive region. The optically reflective region is provided with a first prism annularly disposed outside the optically effective refractive region and a second prism annularly disposed outside the first prism. The first prism and the second prism are arranged concentrically. A first lead angle portion is formed between the first prism and the second prism, and the radius of the first lead angle portion is between 0.01 mm and 0.019 mm to increase the effective working area of the first reflection surface and the second refraction surface.

Abstract: A lens structure formed by materials in different refractive indexes includes a sphere, a first lens and a separation layer which is disposed between the sphere and the first lens. The sphere and the first lens have a different refractive index and the sphere is a round ball. The first lens is formed on the sphere that part of the sphere is exposed out of the first lens, and the first lens includes a first light absorption curve. The separation layer includes a transparent section opposite to the first light absorption curve. When a light beam passes through the second portion of the sphere to form a first light condensing effect and enter the sphere, the light beam will then pass through the transparent section to enter the first lens, forming a second light condensing effect after passing through the first light absorption curve.

The light output surface has a logo pattern and a number of microstructures thereon. The microstructures are arranged along a contour of the logo pattern. The light source is arranged adjacent to the light incident surface and configured for emitting light beams. The microstructures are structured and arranged in a manner such that the light beams exiting from the output surface illuminate the logo pattern and the microstructures, and the light intensity at the microstructures is greater than that at the logo pattern, thus producing a stereoscopic logo pattern.
