摘要:
The invention relates to a method for aligning a luminous spot of light exiting at least one light guide on an optical converter, wherein the exit surface 7 of the fiber has an angle α relative to the longitudinal axis of the fiber which is different from 0°, the position of the luminous spot on the converter being aligned by adjusting the angle α. The invention also relates to a device comprising a light guide from which light exits and is incident on an optical converter to at least a substantial extent, thereby forming a luminous spot, wherein the exit surface 7 of the fiber has an angle α relative to the longitudinal axis of the fiber which is different from 0°, the position of the luminous spot on the converter being aligned by adjusting the angle α. In another embodiment, the invention relates to a conversion module as a part of a lighting device. The conversion module is operated with excitation light of a light source, a fiber-optic light guide being used. For holding a converter for producing the useful light a support element is provided while the light guide is positioned and held by a decoupling head. In another embodiment, the invention relates to a converter-cooling body composite, wherein the cooling body and the converter are interconnected such that the connection between the converter and the cooling body preferably has high reflectance and both the connection between the converter and the cooling body as well as the entire system has low thermal resistance and a long life expectancy.
摘要:
A laser-activated remote phosphor (LARP) target comprising a substrate 8114), a dichroic filter(120) disposed on the substrate, a phosphor converter (102) disposed on the dichroic filter, and an aperture structure (230) disposed on the phosphor converter. The phosphor converter comprises a luminescent material that at least partially converts a primary laser pump light (110) into a secondary light (108) having a different peak wavelength. The dichroic filter substantially transmits the primary laser pump light and substantially reflects the secondary light. The aperture structure covers the lighting emitting surface except for an aperture (240) in the aperture structure whereby a substantial portion of secondary light passes through the aperture in the aperture structure for coupling into an optical system.

摘要:
L'invention concerne essentiellement le domaine des matériaux nanocomposites hybrides pour applications en projection volumétrique, tel que par exemple en imagerie 3D (tel que le domaine du divertissement ou domaine médical). En particulier, une matrice de projection hybride binaires est décrite, comprenant au moins deux types de (nano)particules et/ou molécules différentes (points quantiques, nanoparticules métalliques; nanotubes de carbone), un procédé de fabrication de cette matrice et aussi un système et une méthode de projection en 3D comprenant l'utilisation de ladite matrice. L'introduction du deuxième type de particules permet de modifier les propriétés de la matrice afin d'atteindre de meilleures performances de projection volumétrique ou encore générer de nouvelles caractéristiques qui n'existaient pas à une seule particule. La nouvelle matrice permet aussi de diminuer la puissance du laser utilisé pour la projection tout en obtenant une luminosité équivalente par rapport aux matrices déjà existante.
