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.

Lighting apparatus with luminophore on a moveable carrier

An airfield lighting device, comprising: at least one first light-emitting diode (LED) on a first base body; a first thermally conductive tube with a heat transmission medium; a first heat sink; and a housing, in which the first base body and the first thermally conductive tube are arranged. The first thermally conductive tube is thermally coupled to the first base body and to the first heat sink. The heat transmission medium can circulate in the first thermally conductive tube, such that heat which is produced by the at least one first LED during operation can be dissipated from the first base body to the first heat sink.
