摘要： An illumination device (1) for a motor vehicle headlight, including illumination units arranged next to one another, which respectively have a light source, primary optical device, and a secondary optical device. The primary optical devices are held in a common holding element formed by a transparent body. In the body, an overcoupling protective device in the form of a through hole in the body is provided between two adjacent receiving through holes in which a primary optical device is respectively held. The through hole of the overcoupling protective device is delimited by two side faces, which face the receiving through holes of the primary optical devices. Light deflection means are designed to deflect at least part of the rays of light entering the body such that part of the rays of light does not enter the adjacent illumination unit or strike the secondary optical device of the adjacent illumination unit.

摘要： Illumination device (10) for a motor vehicle headlight, which comprises the following:



a first light module (100) for producing light distribution,
a bulb shield (300) having a bulb shield (300), which comprises an optically relevant shield edge (310) for producing a cut-off line,
a projection lens (400) with an optical axis (A), which is designed to image the light that can be produced by the first light module (100) in front of the illumination device (10), wherein the projection lens (400) is designed as a Fresnel lens, which Fresnel lens has a base body (410) and several annular steps (420) arranged on the base body (410), wherein each step (420) has a main surface (420a) to project the light beams of the at least one light module (100) in front of the illumination device (10) and a sloping surface (420b) extending from the base body (410) to the main surface (420a), wherein the sloping surface (420a) forms a slope angle (W2) to the optical axis (A), and wherein the main surface (420a) and the sloping surface (420b) form a step edge (430) in a common surface section line, wherein the slope angle (W2) varies continuously along the circumference of a step edge (430).
