Patent ID: 8905608

Claim:
An optical body for a vehicle light for coupling in, passing on and emitting the light delivered by a light source in a conical spatial region, comprising: a light emission surface and a recess which is opposite the light emission surface and which has a longitudinal axis and in which the light source can be so positioned that the central axis of the conical spatial region coincides with the longitudinal axis of the recess and wherein the recess has an annularly closed inner peripheral wall which surrounds the longitudinal axis and a cover wall which extends transversely relative to the longitudinal axis and which is provided with an optical structure for altering a spread angle of a light beam passing therethrough, wherein the optical structure of the cover wall of the recess includes a plurality of optically active surface portions which are arranged around a point at which the longitudinal axis of the recess passes through the cover wall and each of which has a focal point lying on the longitudinal axis and wherein the focal points of at least two of said surface portions are mutually spaced in along the longitudinal axis.
