Title
(EN) AN ARRANGEMENT COMPRISING AN OPTICAL DEVICE AND A REFLECTOR
(FR) ARRANGEMENT COMPRENANT UN DISPOSITIF OPTIQUE ET UN RÉFLECTEUR
Abstract
(EN) According to an embodiment of the present inventive concept there is provided an arrangement 4 comprising: an optical device 8 including a radially inner beam forming portion 10 and a radially outer portion 12, at least partly enclosing the radially inner portion 10. The arrangement 4 further comprises a reflector 6 arranged to reflect, in a first direction towards the radially outer portion 12, light emitted by a light source 2 such that a first optical path is formed from the light source 2 to the radially outer portion 12, via the reflector 6. The radially outer portion 12 is transparent such that incident light reaching the radially outer portion 12 along the first optical path exits the radially outer portion 12 in a direction parallel to the first direction, and at least one of scattering and attenuating for light reaching the radially outer portion 12 along a second optical path extending directly between the light source 2 and the radially outer portion 12. The radially outer portion 12 may thus act as a clear exit window for reflected light R, contributing to the intensity of a central beam F formed by the radially inner beam forming portion 10, while preventing transmission of direct light D which otherwise could produce glare.
(FR) La présente invention, dans un mode de réalisation, concerne un arrangement (4) comprenant : un dispositif optique 8 incluant une portion intérieure radiale (10) de formation de faisceau et une portion extérieure radiale (12) qui entoure au moins partiellement la portion intérieure radiale (10). L'arrangement (4) comprend en outre un réflecteur (6) disposé pour réfléchir, dans une première direction vers la portion extérieure radiale (12), la lumière émise par une source de lumière (2) de telle sorte qu'un premier chemin optique est formé entre la source de lumière (2) et la portion extérieure radiale (12) par le biais du réflecteur (6). La portion extérieure radiale (12) est transparente de sorte que la lumière incidente qui atteint la portion extérieure radiale (12) le long du premier chemin optique sort de la portion extérieure radiale (12) dans une direction parallèle à la première direction, et au moins de sorte à diffuser ou atténuer la lumière qui atteint la portion extérieure radiale (12) le long d'un deuxième chemin optique qui s'étend directement entre la source de lumière (2) et la portion extérieure radiale(12). La portion extérieure radiale (12) peut ainsi faire office de fenêtre de sortie transparente pour la lumière réfléchie (R), contribuant à l'intensité d'un faisceau central (F) formé par la portion intérieure radiale (10) de formation de faisceau, tout en empêchant la transmission de la lumière directe (D) qui pourrait sinon produire un éblouissement.
