Abstract (en)
[origin: US2015070926A1] The invention relates to a projection lens for use in an LED module of a motor vehicle headlamp. The LED module has a light source in the form of an LED matrix including numerous LED chips disposed in a matrix adjacent to and/or above one another, a primary lens including numerous primary lens elements disposed in a matrix adjacent to and/or above one another for bundling light emitted from the light source, and a projection lens. The projection lens projects a light exit surface of the primary lens to generate a predefined light distribution on a surface in front of the vehicle. The projection lens is designed such that it generates at least two separate images of the light exit surface of the primary lens on its image side, which are offset to one another in the horizontal direction.
