Lighting device for a motor vehicle headlight

A lighting device (10) for a motor vehicle headlight, comprising:

• at least one first light module (100) having at least one light source (110) for generating a low beam distribution in the direction of a main beam direction,
• at least one second light module (200) for generating a high beam distribution, the second light module (200) comprising at least one light source (210) and a light-guiding body (220), in which light guide body (220) light from the light source (210) can be irradiated via a coupling surface (221) into the light-guiding body (220) and can be decoupled via a decoupling surface (222) in the direction of the main beam direction,
• the light-guiding body (220) having a first reflective surface (223a) on a roof side (223) extending from the coupling surface (221) to the decoupling surface (222) and the light guide body (220) being arranged relative to the first light module (100) in such a way that at least part of the decoupled light that can be generated by the first light module (100) can be reflected on the first reflective surface (223a), and
• at least one projection lens (500) that is configured to image the light that can be generated by the first and second light module (100, 200) in front of the lighting device (10),
• the light-guiding body (220) being designed in such a way that an aperture for part of the light that can be generated by the first light module (100) for generating the low beam distribution is arranged between the first light module (100) and the projection lens (500),
• wherein the lighting device (10) comprises at least one third light module (300) having a light source for generating additional light distribution, and the light-guiding body (220) of the second light module (200) having a bottom surface (224) facing away from the roof surface (223), which bottom surface has a second reflective surface (224a) at least in portions,
• the third light module (300) being arranged in such a way that at least part of the decoupled light that can be generated by the third light module (300) can be reflected by the second reflective surface (224a) of the light-guiding body (220), and
• the projection lens (500) being configured to image the light that can be generated by the third light module (300) in front of the lighting device (10),
• wherein the bottom surface (224) and the decoupling surface (222) of the light-guiding body (220) form a lower edge (260) in a common surface intersection line, and
• wherein the second reflective surface (224a) ends at a distance from the lower edge (260) and releases a coupling region (270) on the underside into which part of the light from the third light module (300) can be coupled and can be decoupled again via the decoupling surface (222) of the light-guiding body (220).
