    Abstract: An optical device is provided including a light-imaging component configured to focus light fed to the light-imaging component in at least one focusing spot, wherein the light fed includes at least one predefinable wavelength; and a conversion apparatus including at least one phosphor which is designed to convert light having the at least one predefinable wavelength into conversion light, wherein the conversion apparatus is arranged in such a way that the at least one phosphor is arranged in the focusing spot of the light-imaging component. The light-imaging component is configured to generate at least two focusing spots, and the conversion apparatus is arranged in such a way that the at least two focusing spots are positioned on the at least one phosphor.

    Abstract: A luminaire includes a reflector arrangement and a light generating unit, which emits its light onto the reflector arrangement. The reflector arrangement includes at least two shell-layer-shaped reflector rings which are arranged coincidentally with regard to their axes of symmetry. The reflector rings have different middle radii, are arranged in a manner one nested in another, and are embodied as total internal reflection reflectors.

    Abstract: Various embodiments may relate to a lighting apparatus, including at least one primary light source for generating primary light, a reflector having two spaced-apart focal spots, a guiding optical unit disposed downstream of the at least one primary light source and serving for guiding the primary light to a first focal spot of the reflector, and a conversion device for at least partly converting the primary light into secondary light having a different wavelength which is situated at the second focal spot. The reflector has a first reflective partial region, to which the two focal spots are assigned, and a second reflective partial region, which is a partial region retroreflective for the second focal spot. The primary light emitted by the at least one primary light source is incident on the first partial region.

    Abstract: A lighting apparatus includes at least one primary light source for emitting primary light, at least one phosphor body arranged at a distance from the primary light source, for converting the wavelength of primary light into secondary light, and at least one at least partly dichroic mirror, which at least partly deflects primary light radiated thereon onto at least one phosphor body and which passes secondary light radiated by the phosphor body. Used light radiated by the lighting apparatus contains the secondary light and primary light radiated by at least one primary light source, and the dichroic mirror includes at least one first and second mirror regions, in such a way that the first mirror region deflects primary light onto at least one phosphor body and passes secondary light incident from the phosphor body, and that the second mirror region deflects primary light in a manner circumventing the phosphor body.

    Abstract: A method for detecting damage to a converter device of a lighting apparatus is provided. The method may include irradiating the converter device with input light, detecting a useful light portion emitted principally by a first section of the converter device by means of a first sensor element. A first detection signal is obtained, detecting a useful light portion emitted principally by a second section of the converter device, said second section being different than the first section, by means of a second sensor element. A second detection signal is obtained. The method further may include automatically obtaining damage information about the converter device from a ratio or a difference of the first detection signal with respect to either the second detection signal or a comparison signal formed therefrom.
