Patent ID: 8469567

Claim:
An optical lens system for use in a vehicle light, the optical lens system comprising: a lens including a light incident surface and a light output surface, the light output surface disposed on an opposite side with respect to the light incident surface, wherein the light incident surface includes a center light incident surface and a surrounding light incident surface where a plurality of prisms are radially arranged around the center light incident surface, the light output surface includes a center light output surface corresponding to the center light incident surface and a surrounding light output surface corresponding to the plurality of prisms, each of the plurality of prisms includes an incident prism surface and a reflective prism surface, the incident prism surface is configured to allow light emitted from a light source disposed in front of the light incident surface to enter the lens, the reflective prism surface is configured to reflect light that is emitted from the light source, enters the incident prism surface, and reaches the reflective prism surface, toward the surrounding light output surface, the center light output surface is configured to allow light that is emitted from the light source and enters the center light incident surface to be output, and the surrounding light output surface is configured to allow light reflected from the reflective prism surface to be output, wherein: the center light incident surface is formed as a convex lens surface configured to extend in a convex manner toward the light source: the center light output surface is formed as a lens surface that is configured to diffuse light emitted from the light source and which enters the lens through the center light incident surface in a horizontal direction: the surrounding light output surface is formed as a lens surface that is configured to diffuse light reflected from the reflection prism surfaces in a vertical direction and a horizontal direction so as to direct the light toward a center position.
