Abstract

Wynalazek dotyczy oświetlacza zawierającego źródło światła w postaci matrycy diod LED i układ optyczny. Matryca (3) diod LED posiada centralny otwór z umieszczoną tam soczewką (4), a przed matrycą (3) diod LED znajduje się matryca (2) soczewek skupiających, zrównolegniających wiązkę promieniowania optycznego. Matryca (2) soczewek skupiających posiada centralny otwór nie mniejszy od średnicy soczewki (4). Przed matrycą (2) soczewek skupiających znajduje się zwierciadło wklęsłe (1), umieszczone w odległości umożliwiającej skupienie wszystkich równoległych wiązek świetlnych wychodzących z soczewek matrycy (2) soczewek skupiających poprzez odbicie od zwierciadła wklęsłego (1) na soczewce (4). Bezpośrednio za soczewką (4) znajduje się światłowód (5). Matryca (3) diod LED, matryca (2) soczewek skupiających oraz zwierciadło wklęsłe (1) umocowane są w sposób mechaniczny trwale w obudowie (8).The invention relates to an illuminator comprising a light source in the form of an LED matrix and an optical system. The matrix (3) of the LEDs has a central hole with the lens (4) placed there, and in front of the matrix (3) of the LEDs there is a matrix (2) of focusing lenses that parallel the beam of optical radiation. The focusing matrix (2) has a central hole not smaller than the diameter of the lens (4). In front of the matrix (2) of the focusing lenses there is a concave mirror (1), placed at a distance enabling focusing of all parallel light beams coming out of the matrix lenses (2) of the focusing lenses by reflection from the concave mirror (1) on the lens (4). Directly behind the lens (4) is the optical fiber (5). The matrix (3) of the LEDs, the matrix (2) of the focusing lenses and the concave mirror (1) are mechanically fixed in the housing (8).
