  • Patent number: 7762697
    Abstract: A light-emitting element is disposed to face the front side such that an end point of a rectangular or square light-emitting chip corresponding to the vehicle's own lane is positioned at a rear focal point of a convex lens. An additional lens is disposed to surround the convex lens. The additional lens includes an incident surface, a reflection surface, and an emitting surface. The additional lens is divided into a-plurality of fan-shaped areas in a circumferential direction with respect to an optical axis Ax.

  • Patent number: 7638027
    Abstract: A method for fabricating a microstructure array, such as a microlens array, and a mold for forming the microlens array, includes the steps of forming an array of microstructures with a curved profile in a discrete form on a substrate, and uniformly forming a continuous layer on the substrate and the discrete microstructures. Optically-unusable regions between the discrete microstructures, such as microlenses, can be readily reduced or eliminated by forming the continuous layer until flat portions between the microstructures disappear.
