  • Patent number: 10132471
    Abstract: A lighting device includes a light source, a reflector having an ellipsoidal reflection surface, an aspherical lens, and an exit pupil. The source is arranged at a first focal point of the reflection surface and a part of the emitted light is reflected from the reflection surface in the direction of a second focal point. The pupil is arranged offset with respect to the second focal point. The lens is arranged between the reflection surface and the pupil in a beam path with the reflected light and is shaped such that a first part of the reflected light passes through the lens with an aperture angle altered by not more than 5° in a central region and passes through the pupil and a second part of the reflected light penetrates through the lens in an outer region and is deflected by the lens and is consequently guided through the pupil.
