Abstract:
An apparatus for presenting an image for a heads-up display includes three arrays of light-emitting diodes, wherein the light-emitting diodes of an array are arranged and output electromagnetic beams in an emission direction of an emission side of the array, the light-emitting diodes output an electromagnetic beam with a first opening angle in the emission direction, a collimation apparatus provided on the emission side at a specified spacing in front of the array of the light-emitting diodes, wherein the collimation apparatus reduces the first opening angles of the beams of the light-emitting diodes downstream of the collimation apparatus in the emission direction to a second opening angle, the second opening angle is smaller than the first opening angle, and a combination optical unit arranged downstream of the collimation apparatus in the emission direction, the combination optical unit superposes the electromagnetic rays from the three arrays to form an image for the head-up display.
