Optical illumination assembly, lighting device and motor vehicle

A lighting device, comprising an optical illumination assembly, wherein the optical assembly includes a light source and a printed circuit board, the light source being arranged on the printed circuit board and emitting light, a light reflector, the light reflector being provided with a reflective surface, the reflective surface being configured to collect light emitted by the light source, and reflect the light in a light beam along an optical axis of the optical illumination assembly, and an optical projection apparatus, the optical projection apparatus being configured to project the light beam, wherein the light source is provided with a main light-emitting range, and the printed circuit board is inclined towards the light reflector relative to the optical axis, to prevent light emitted by the light source within the main light-emitting range from directly reaching the optical projection apparatus and being projected.
