An illumination device for a motor vehicle headlight for producing light distribution with a cut-off line. The device includes a light-permeable body, a light injection element and a light source, wherein the light injection element is designed to inject light emitted by the light source into the light-permeable body. The light injection element has a first deflection structure, which is configured such that light from the light source which enters the light injection element and strikes the deflection structure is totally reflected. The totally reflected light is directed at a second deflection structure which is arranged on an upper boundary surface of the light-guiding body and configured such that the light striking it is deflected to a first surface region of a first lower boundary surface of a screen device. The surface region deflects the light striking it into a region of the projection device, which projects the light as a sign light light beam into a region of the light distribution located above the cut-off line as additional light distribution, e.g., as sign light light distribution.

Illumination device for a motor vehicle headlight and motor vehicle headlight

An illumination device for a motor vehicle headlight for producing light distribution with a cut-off line is provided. The illumination device has a light source, a light-permeable body, a light injection element for injecting light emitted by the light source into the light-permeable body, and a projection device, which has a focal surface and an optical axis. First and second optical exit structures are provided on a lower boundary surface of the body, which are configured such that light from the light source strikes an optical exit structure, exits the light-permeable body, propagates outside the light-permeable body to the projection device, and directly strikes the projection device and is thereby projected as sign light light beams into a region located above the cut-off line and forms a sign light light distribution. Two sign light light beams are projected in different partial regions of the region above the cut-off line.
