OUTDOOR DRIVING MIRROR WITH SPHERICAL AND ASPHERICAL SURFACES, CAPABLE OF PREVENTING A DEAD ZONE CAUSED BY THE LEVEL OF A DRIVER SEAT THROUGH VERTICAL ECCENTRICITY

摘要

PURPOSE: An outdoor driving mirror with spherical and aspherical surfaces is provided to prevent the distortion of an image at the outer periphery of the driving mirror using the optical characteristics of the aspherical surface.;CONSTITUTION: An outdoor driving mirror(50) comprises a center spherical portion and an aspherical portion. The center spherical portion comprises a curvature having a pre-set size. The curvature radiuses of the left, right, upper and lower sides of the driving mirror are gradually reduced from the boundary of the center spherical portion to the edge of the outer periphery. The refractive power of the aspherical portion increases.;COPYRIGHT KIPO 2013
