摘要： An optical surface for softening a light/dark border of a lighting device for vehicles, having a grid of lens elements distributed over a base surface, by means of which a light bundle passing through the optical surface can be diffused in relation to a main direction, wherein the lens elements are each designed as micro-lens elements, which, on one hand, exhibit a central main emission surface, which follows a contour of the base surface, by means of which the light beams of the light bundle are deflected in a main direction corresponding to the contour of the base surface, and on the other hand, exhibit subsidiary emission surfaces, running at an angle to the central main emission surface, by means of which light beams of the light bundle are diffused in a diffusion direction in relation to the main direction.

摘要： An optical surface for softening a light/dark border of a lighting device for vehicles, having a grid of lens elements distributed over a base surface, by means of which a light bundle passing through the optical surface can be diffused in relation to a main direction, wherein the lens elements are each designed as micro-lens elements, which, on one hand, exhibit a central main admission surface, which follows a contour of the base surface, by means of which the light beams of the light bundle are deflected in a main direction corresponding to the contour of the base surface, and on the other hand, exhibit subsidiary admission surfaces, running at an angle to the central main admission surface, by means of which light beams of the light bundle are diffused in a diffusion direction in relation to the main direction.
