Abstract: An endoscope is provided that includes a first component, a second component, a light source, an image capturing element, and a light guide. The second component has a proximal end and a distal end with proximal end coupled to the first component. The light source is integrated in the first component and includes a laser and a converter. The laser emits primary light and the converter converts the primary light at least partially into secondary light that has a different wavelength. The image capturing element is arranged at the distal end. The light guide has an optical fiber that extends through the second component. The converter is coupled to the proximal end such that the primary and secondary light is injected into the optical fiber, is conducted from the proximal end to the distal end, and emitted at the distal end.

Abstract: A fiber-optic conversion module is provided as part of a lighting device on a vehicle. The module includes optical fibers with connectors, a light exit head, and a converter mounted on a cooling element. Shorter wavelength excitation light is fed to the optical fibers that emit the excitation light towards the converter arranged at an angle relative to the beam direction, at a light spot that remits useful light in a radiation angle in form of a cone of useful light and reflects excitation light as a Fresnel reflection substantially outside the cone of useful light, where Fresnel reflection is made harmless by a light stop.

Abstract: A method and device for aligning a light spot of light exiting from at least one light guide on an optical converter are provided. The device includes a light guide from which light exits and is incident on an optical converter to at least a substantial fraction, thereby forming a light spot thereon, wherein the exit surface of the fiber has an angle relative to the longitudinal axis of the fiber which is different from 0°, and the position of the light spot on the converter is aligned by adjusting the angle. A conversion module as a part of a lighting device is also provided that is operated with excitation light of a light source using a fiber-optical light guide.
