Abstract
The lighting device () has at least one light generation device () for generating a primary light (P), a first luminophore () for converting the wavelength of the primary light (P) to a first secondary light (S), and a second luminophore () for converting the wavelength of the primary light (P) to a second secondary light (S), the first luminophore () being located on a movable support (), which is provided in order to alternatively move the first luminophore into and out of a beam path of the primary light (P), and the second luminophore being located on a stationary support (). The invention also relates to a method for generating wavelength-converted secondary light from primary light with alternating irradiation of a first luminophore located on a movable support and of a second luminophore located on a stationary support by the primary light. The invention can be used, for example, as a projection device for film and video projection, in endoscopy, for lighting effects in the entertainment industry, for medical irradiations as well as in the automobile industry, in particular as a head light for motor vehicles.
