Abstract
An LED projection module () includes two or more LED light sources which each consist of one or more light-emitting diodes that couple light via a light coupling-in point associated therewith into an optical waveguide. Light exits from the optical waveguides via a light decoupling point. The exiting light is projected by a projection lens to form at least one light distribution. The optical waveguides for the individual LED light sources are arranged laterally side by side in a horizontal plane and border one another directly such that light can pass over between adjacent optical waveguides. The individual light outlet surfaces are arranged side by side and form a total-light light outlet surface. One or more indentations are provided in the total-light light outlet surface, between the individual light outlet surfaces, and in each case extend at least over part of the vertical extension of the total-light light outlet surface.
