The invention relates to a combined lens at least includes a lens and a reflector. Viewed from a reflective light path, parallel light is refracted twice by an incident surface and an emergent surface of the lens, is reflected once by the reflector, and then is converged to one point, namely a focus of the combined lens. A distance between the lens and the reflector is less than a focal length of the lens. The lens may be a convex lens or a concave lens, and the reflector may be a convex mirror, a plane mirror or a concave mirror. In addition, in a traditional lens, a focus position is controlled through two optical surfaces, namely an incident surface and an emergent surface, the lens is usually thicker in the case of the same focal length, and moreover, an optical axis direction is generally a center line of the lens.

A lighting device for a motor vehicle has a laser light source for producing laser light and a converting unit having a reflective converting layer, at which laser light originating from the laser light source is directed, during operation of the lighting device, such that a white light source is produced at the converting layer. A reflector is provided, which has an elliptical reflection surface, which corresponds to a portion of an ellipsoid containing a vertex of the ellipsoid. The reflector is shaped and arranged such that a first focal point of the ellipsoid lies within the white light source and the white light source is optically imaged in the form of a real intermediate image, which includes a second focal point of the ellipsoid, by way of the reflector. The lighting device also has a secondary optical unit, by which a light distribution in the environment of the motor vehicle is produced from the real intermediate image. An aperture for limiting the light distribution in the environment of the motor vehicle is arranged at the location of the real intermediate image.

A vehicle lamp includes a lamp unit configured such that emitted light from a light source is emitted toward the front of the lamp via a projection lens. The lamp unit includes first and second light sources as the light source, which are turned on at respective required turning on modes.
