Title (DE) OPTISCHES SYSTEM ZUM BEEINFLUSSEN DER LICHTABGABE EINER LICHTQUELLE
(EN) OPTICAL SYSTEM FOR INFLUENCING THE LIGHT OUTPUT OF A LIGHT SOURCE
(FR) SYSTÈME OPTIQUE DESTINÉ À INFLUER SUR L'ÉMISSION DE LUMIÈRE D'UNE SOURCE DE LUMIÈRE
Abstract:
(DE) Ein optisches System zum Beeinflussen der Lichtabgabe einer Lichtquelle weist einen topfartigen Reflektor (20), der eine Lichtaustrittsöffnung (21) aufweist, sowie eine Linse (10) auf, welche dazu ausgebildet ist, einen ersten Anteil des Lichts über die Lichtaustrittsöffnung (21) des Reflektors (20) in eine durch die Linse (10) definierte Vorzugsrichtung abzustrahlen, wobei die Linse (10, 60) ferner dazu ausgebildet ist, einen zweiten Anteil des Lichts seitlich derart abzugeben, dass dieser Anteil auf die Reflektorinnenwand fällt.
(EN) The invention relates to an optical system for influencing the light output of a light source comprising a cup-like reflector (20), which has a light outlet opening (21), and comprising a lens (10), which is designed to radiate a first proportion of the light via the light outlet opening (21) of the reflector (20) in a preferred direction defined by the lens (10), wherein the lens (10, 60) is also configured to emit a second proportion of the light laterally in such a way that said proportion falls onto the reflector inner wall.
(FR) L'invention concerne un système optique destiné à influer sur l'émission de lumière d'une source de lumière, lequel système présente un réflecteur (20) du type pot qui présente une ouverture de sortie de lumière (21), ainsi qu'une lentille (10) conçue pour réfléchir une première partie de la lumière par l'ouverture de sortie de la lumière (21) du réflecteur (20) dans une direction préférentielle définie par la lentille (10), ladite lentille (10, 60) étant en outre conçue pour émettre une deuxième partie de la lumière latéralement de sorte que cette partie soit incidente sur la paroi intérieure du réflecteur.
