Lighting device for a motor vehicle headlight

A lighting device (1) for a motor vehicle headlight, comprising:

• a plurality of light sources;
• a light guide unit (3) that is made of a light-conducting solid body and comprises a plurality of light guides (3b);
• and
• a downstream projection lens (4) including a focal plane (E),
• wherein each light guide (3b) comprises a light incoupling surface (3b′) for coupling light of a light source (2) into the light guide (3b), the light guides (3b) converging toward a shared light outcoupling surface (3a) of the light guide unit (3), the light outcoupling surface (3a) being configured to radiate light into the projection lens (4) and being essentially located in the focal plane (E) of the projection lens (4),
• wherein the light guide unit (3) comprises at least one translucent deflection element (6), which extends along the light outcoupling surface (3a) in a rib-shaped manner and protrudes beyond the light outcoupling surface (3a) in the direction of the projection lens (4), or is formed as a recess inside the light outcoupling surface (3a) counter to this direction, the deflection element (6) being designed to at least partially deflect light entering the deflection element (6) from the light outcoupling surface (3a) in the direction of the projection lens (4), the deflection element (6) having a triangular cross-section, and
• wherein the light guide unit (3) comprises two or more deflection elements (6), which are disposed on top of one another at the light outcoupling surface (3a).
