Zusammenfassung: | The invention relates to a lighting device (1) for a motor vehicle headlight, comprising:a light module (2), wherein the light module (2) comprises a light source (2a) and a collimator (3), which is set up in such a manner that the light generated by the light source (2a) is emitted via a light-emitting surface (3a) in a light propagation direction (4),an optical element (5) having a light-coupling surface (5a) and a light-decoupling surface (5b), wherein the light of the collimator is guided through the optical element (5), wherein the light-decoupling surface (5b) of the optical element (5) has multiple optical elements (6) through which the light is emitted as a divergent light beam, whereinthe light-emitting surface (3a) of the collimator (3) is formed from multiple lenses (7), wherein each lens (7) is set up for emitting the light of the light source (2a) to the light-coupling surface (5a) of the optical element (5) in a divergent manner, wherein all lenses (7) have essentially the same focal length, wherein the collimator (3) and the optical element (5) are spaced apart from each other, wherein the distance between them essentially corresponds to the focal length of the lenses (7). |
