Lighting device for a motor vehicle headlight of a single-track motor vehicle for generating a segmented light distribution, the lighting device comprising - an optical body comprising a base body and a plurality of light guide bodies projecting from the base body for forming a definable segmented light distribution from the light of light sources, which light guide bodies each have a light entry surface, into which light from light sources can be fed, and have an exit surface from which light which can be fed into the respective light guide body emerges, the exit surfaces of adjacent light guide bodies forming a common exit surface of the optical body, - a plurality of light sources, at least one light source being assigned in each case to an entry surface of a light guide body, - a projection optic with an optical axis, which projection optic is set up to image the light emerging from the common exit surface in front of the illumination device in the direction of a main radiation direction, the base body has a first and a second light-emitting half (110a, 110b), each light-emitting half (110a, 110b) having light guide elements which are arranged at least in a first row along a straight line and in a second row along a straight line, wherein the straight lines of the first and second rows (R1, R2) are arranged relative to one another by a first angular offset, and wherein the first and second light-emitting halves (110a, 110b) are arranged on the base body in mirror symmetry relative to one another about a vertical axis of symmetry, characterized in that each light guide body has side surfaces extending from the entry surface to the exit surface, the exit surface being bounded in each case by two narrow sides and two longitudinal sides, the side surfaces of at least one light guide body being curved, wherein that side surface of the light guide body which is directed towards the vertical axis of symmetry is convex, and that side surface of the light guide body which is directed in the opposite direction to the vertical axis of symmetry is concave, and wherein each row (R1, R2) has an outermost light guide body arranged away from the vertical axis of symmetry and at least one inner light guide body, wherein the at least one inner light guide body of each row (R1, R2) has the curved side surfaces. - an optical body comprising a base body and a plurality of light guide bodies projecting from the base body for forming a definable segmented light distribution from the light of light sources, which light guide bodies each have a light entry surface, into which light from light sources can be fed, and have an exit surface from which light which can be fed into the respective light guide body emerges, the exit surfaces of adjacent light guide bodies forming a common exit surface of the optical body, - a plurality of light sources, at least one light source being assigned in each case to an entry surface of a light guide body, - a projection optic with an optical axis, which projection optic is set up to image the light emerging from the common exit surface in front of the illumination device in the direction of a main radiation direction, the base body has a first and a second light-emitting half (110a, 110b), each light-emitting half (110a, 110b) having light guide elements which are arranged at least in a first row along a straight line and in a second row along a straight line, wherein the straight lines of the first and second rows (R1, R2) are arranged relative to one another by a first angular offset, and wherein the first and second light-emitting halves (110a, 110b) are arranged on the base body in mirror symmetry relative to one another about a vertical axis of symmetry, characterized in that each light guide body has side surfaces extending from the entry surface to the exit surface, the exit surface being bounded in each case by two narrow sides and two longitudinal sides, the side surfaces of at least one light guide body being curved, wherein that side surface of the light guide body which is directed towards the vertical axis of symmetry is convex, and that side surface of the light guide body which is directed in the opposite direction to the vertical axis of symmetry is concave, and wherein each row (R1, R2) has an outermost light guide body arranged away from the vertical axis of symmetry and at least one inner light guide body, wherein the at least one inner light guide body of each row (R1, R2) has the curved side surfaces.
