Light emitting module, lighting device and vehicle lamp

The invention discloses an illumination module for improving light spot yellowing, and relates to the technical field of vehicle lamp illumination. Comprising a light source, a reflector and an outer lens. Light rays emitted by the light source are reflected to the outer lens through the reflecting surface of the reflecting mirror, and then form light spots after being subjected to primary refraction through the incident surface of the outer lens and secondary refraction through the emergent surface of the outer lens; a longitudinal first focus and a transverse second focus of the outer lens are separated from each other, and the second focus is closer to the reflector relative to the first focus in the direction of the optical axis; in the longitudinal direction, when light is secondarily refracted on the light-emitting face of the outer lens, the light inclines along the side, close to the center axis of the outer lens, of the normal of the light-emitting face, and parallel light is emitted. In the transver
