Zusammenfassung: | The invention is associated with an illuminator containing light sources in the form of a LED diode matrix and an optical system. The LED diode matrix (3) has a central hole with the lens (4) situated there, and in front of the LED diode matrix (3) there is situated the focusing lens matrix (2) which makes the optic radiation beams parallel. The focusing lens matrix (2) has a central hole, no smaller than the diameter of the lens (4). In front of the focusing lens matrix (2), there is situated a concave mirror (1) at a distance that allows to focus all the parallel light beams leaving the focusing lens matrix (2), by reflecting from the concave mirror (1) on the lens (4). Directly behind the lens (4) there is situated the fiber optic cable (5). The LED diode matrix (3) and the focusing lens matrix (2) and the concave mirror (1), are permanently attached mechanically in the housing (8).
L'invention concerne un illuminateur contenant des sources de lumière sous la forme d'une matrice de LED, et un système optique. La matrice de LED (3) comporte un trou central qui abrite la lentille (4) et, devant la matrice de LED (3) se trouve la matrice de lentilles de mise au point (2) qui rend les faisceaux de rayonnement optique parallèles. La matrice de lentilles de mise au point (2) comporte un trou central, qui n'est pas plus petit que le diamètre de la lentille (4). Devant la matrice de lentilles de mise au point (2) se trouve un miroir concave (1), à une distance qui permet de concentrer tous les faisceaux de lumière parallèle sortant de la matrice de lentilles de mise au point (2), via une réflexion depuis le miroir concave (1) sur la lentille (4). Directement derrière la lentille (4) se trouve le câble à fibre optique (5). La matrice de LED (3), la matrice de lentilles de mise au point (2), et le miroir concave (1), sont fixés mécaniquement de manière permanente dans le boîtier (8). |
