The invention relates to a lighting device (1) which comprises an imaging unit (2) which is configured to generate an intermediate light image in an imaging plane (ZBE, ZBE′), wherein each imaging unit (2) is composed of a light source (3) and a collimator optics (4), wherein the collimator optics (4) are designed in such a way that the light emitted by the light source (3) in the imaging plane (ZBE, ZBE′) is imaged as an intermediate light image, and wherein the lighting device (1) comprises a projection lens (5) which has a focal plane (BE), and the imaging unit (2) and the projection device (5) are arranged with respect to one another in such a way that the imaging plane (ZBE, ZBE′) lies substantially in the focal plane (BE) of the at least one projection device (5). According to the invention, the imaging unit (2) is designed as a convergence imaging unit (2) being characterized in that the body (4A) of the collimator optics (4) is designed such that the light, which is coupled into the body (4A) via the light coupling region (41A) form a collimator body light bundle (KLB, KLB′) converging into a common virtual intermediate light image plane (VBE, VBE′), wherein the virtual intermediate light image plane (VBE, VBE′) lies in front of the imaging plane (ZBE, ZBE′) of the convergence imaging unit (2) in the direction of light propagation, and wherein a light exit surface (41C) of the body (4A) is designed in such a way that when the collimator body light bundle (KLB, KLB′) exits from the body (4A), the light beams are deflected at the light exit surface (41C) and are formed into an exit light bundle (ALB, ALB′) such that the light beams of the exit light bundle (ALB, ALB′) form the intermediate light image in the imaging plane (ZBE, ZBE′), which intermediate light image lying in the imaging plane is imaged by the projection device (5) into a region in front of the lighting device (1), e.g. into a traffic area in front of the motor vehicle in the case of a lighting device installed in a motor vehicle, as a light distribution or part of a light distribution.
