Latest Patents

The supplied information identifies one patent for Ban: Reflector for a Vehicular Lamp and Method of Producing a Die Therefor. The invention describes a lamp reflector designed to conform to a vehicle body shape, with multiple reflecting sections arranged around the lamp’s optical axis. Its method aims to reduce significant differences in light distribution at the boundaries between those sections.

The disclosed process uses a fundamental surface shaped to fit the vehicle body. Points are selected along a reference curve on that surface, and a small reflecting surface is determined at each point according to the law of reflection. The method then uses surface-normal vectors and spline approximation to generate a closed curve around the optical axis. Ban is credited with 1 patent in the information provided.
