Abstract:
An exterior light lens with a unique and finely textured shape was devised, which provides homogenous luminance, and luminance control technology of exterior light by arranging finely textured shape was developed.Because a die mold with a fine, three-dimensional lens shape is required when mass-producing the lens, we also developed a CAM (Computer Aided Manufacturing) that enables finely textured machining on a free-form surface and automatically produces a smooth machining path on a curved surface.This new technology allowed us to successfully develop a lens that simultaneously achieves transparency and homogenous luminance, properties not achievable through conventional technology.
