    Abstract: The invention proposes a lighting device (1) comprising a wavelength conversion arrangement (12) and a static band-stop filter (14). The wavelength conversion arrangement (12) comprises two wavelength conversion elements, which can be excited to emit conversion light by means of excitation radiation emitted by an excitation source (2). In order to increase the color space which is addressable by means of the two wavelength conversion elements, with the aid of the band-stop filter (14) the shorter dominant wavelength of the conversion light of both wavelength conversion elements is shortened and the longer dominant wavelength is lengthened. For this purpose, the peak wavelength of the band-stop filter (14) is chosen such that it lies between the two dominant wavelengths of the conversion light emitted by the two wavelength conversion elements. The use of a static band-stop filter (14) designed in this way makes it possible to dispense with separate filter elements for each wavelength conversion element. If the wavelength conversion arrangement is designed as a phosphor wheel (12), in particular a separate filter wheel to be synchronized with the phosphor wheel can be dispensed with.

    Abstract: A light module includes a wavelength conversion element and an excitation radiation source to emit excitation radiation having the first wavelength and arranged such that excitation radiation emitted by the excitation radiation source can be radiated onto the wavelength conversion element. The element has an emission spectrum having a red spectral component and a second dominant wavelength, which is less than a first dominant wavelength of the wavelength spectrum of the light to be generated by a predefinable value. The light module includes a long-pass filter arranged such that light emitted by the element can be radiated onto the long-pass filter. The long-pass filter is designed to filter the light emitted by the element and radiated onto the long-pass filter such that the filtered light has the wavelength spectrum of the light to be generated having the predefinable dominant wavelength.

    Abstract: Various embodiments propose an illumination apparatus having a laser apparatus and a phosphor wheel, wherein the phosphor wheel has, in addition to at least one phosphor region for phosphor conversion, at least one transmission region for colored light having a second, greater dominance wavelength from a light source. The beam paths from light source and laser apparatus are e.g. arranged collinearly, wherein the phosphor wheel rotates into the common optical axis of the laser apparatus and light source. By adding colored light having a greater dominance wavelength, the dominance wavelength of a colored light channel that is required for projection applications can also be obtained with colored light converted using efficient phosphor having a dominance wavelength that is too small.

    Abstract: The lighting device (11) has at least one light generation device (12) for generating a primary light (P), a first luminophore (16) for converting the wavelength of the primary light (P) to a first secondary light (S1), and a second luminophore (20) for converting the wavelength of the primary light (P) to a second secondary light (S2), the first luminophore (16) being located on a movable support (15), 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 (21). 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.

    Abstract: A lighting device comprising a phosphor wheel configured such that it temporarily sequentially not only emits the excitation light in a wavelength-converted fashion as conversion light but additionally reflects said excitation light in an unconverted fashion as reflection light. Conversion light and reflection light are guided spatially separately on a conversion light path and reflection light path, respectively, with the aid of a first dichroic mirror and are finally combined with the aid of a second dichroic mirror. In this way, it is possible to combine the reflection light for example as a blue light channel with the conversion light.
