Abstract

Macierzowy układ optyczny rozsyłu światła jest wyposażony w matrycę z diodami LED (1) jako źródłami światła oraz usytuowane równolegle panele płytowe, wewnętrzny (3) i zewnętrzny, formujące wiązki promieni wysyłanych przez diody LED (1), z których co najmniej jeden posiada powierzchnię ograniczającą ilość światła przechodzącego przez układ. Na powierzchni wejściowej wewnętrznego panelu płytowego (3) są uformowane od strony diod LED (1) elementy ogniskujące stanowiące wypukłości (2) usytuowane w osi optycznej każdej diody LED (1), które to wypukłości (2) mają kształt asferyczny o rosnącym w kierunku podstawy promieniu krzywizny, promień wierzchołkowy R wypukłości (2) wynosi od 0,3 do 0,5 odległości s pomiędzy osiami optycznymi sąsiednich diod LED (1), a całkowita grubość (d) wewnętrznego panelu płytowego (3) wynosi od 1,58 do 2,08 odległości s, zaś zewnętrzny panel płytowy ma co najmniej dwie powierzchnie łamiące o wspólnej osi symetrii i obrysie kwadratowym, powierzchnię wklęsłą (7) i sferyczną powierzchnię wypukłą (8), które to powierzchnie łamiące w rzucie czołowym obejmują macierz kwadratową czterech sąsiednich wypukłości (2) na wewnętrznym panelu płytowym (3). Powierzchnię ograniczającą ilość światła przechodzącego przez układ stanowi powierzchnia aperturowa (4), będąca powierzchnią zewnętrzną wewnętrznego panelu płytowego (3), z kołowymi oknami (5) usytuowanymi w osi optycznej każdej diody LED (1).The matrix optical system of light distribution is equipped with a matrix with LEDs (1) as light sources and parallel plate panels, internal (3) and external, forming beams of rays emitted by LEDs (1), at least one of which has a limiting surface amount of light passing through the system. On the entrance surface of the inner plate panel (3) there are formed from the side of the LEDs (1) focusing elements constituting bulges (2) located in the optical axis of each LED (1), which bulges (2) have an aspheric shape with increasing towards the base radius of curvature, the tip radius R of the protuberance (2) is from 0.3 to 0.5 of the distance s between the optical axes of adjacent LEDs (1), and the total thickness (d) of the inner plate panel (3) is from 1.58 to 2 .08 distance s, and the outer plate panel has at least two breaking surfaces with a common axis of symmetry and a square contour, a concave surface (7) and a spherical convex surface (8), which breaking surfaces in frontal projection include a square matrix of four adjacent protuberances ( 2) on the inner plate panel (3). The surface limiting the amount of light passing through the system is the aperture surface (4), which is the outer surface of the inner plate panel (3), with circular windows (5) located in the optical axis of each LED (1).
