Title
(EN) LUMINAIRE WITH HOLLOW OPTICAL SYSTEMS
(FR) LUMINAIRE À SYSTÈMES OPTIQUES CREUX
Abstract
(EN)
A luminaire (100) includes a base (102) supporting multiple light- emitting elements (LEEs) (122); and a first wall (150-i) and a second wall (150-o) each extending along a first direction (101). The first and second walls (150-i, 150-o) have light-reflective surfaces facing each other and forming a hollow channel (152). The light-reflective surfaces have first portions (120) that curve in opposite directions, second portions (130) that are parallel, and third portions (140) that curve in like directions. The first portions (120) are arranged facing the LEEs (110) to provide an input aperture (122) that receives light from the LEEs (110). The third portions (140) are arranged to provide an exit aperture (142) that outputs output light into an ambient environment. The first and second walls (150-i, 150-o) are configured to propagate light from the input aperture (122) to the exit aperture (142).
(FR)
L'invention concerne un luminaire (100) qui comprend une base (102) portant de multiples éléments électroluminescents (LEE) (122) ; et une première paroi (150-i) et une seconde paroi (150-o) s'étendant chacune le long d'une première direction (101). Les première et seconde parois (150-i, 150-o) présentent des surfaces réfléchissant la lumière se faisant face et formant un canal creux (152). Les surfaces réfléchissant la lumière présentent des premières parties (120) qui s'incurvent dans des directions opposées, des deuxièmes parties (130) qui sont parallèles et des troisièmes parties (140) qui s'incurvent dans des directions similaires. Les premières parties (120) sont agencées en vis-à-vis des LEE (110) pour fournir une ouverture d'entrée (122) qui reçoit de la lumière provenant des LEE (110). Les troisièmes parties (140) sont agencées pour fournir une ouverture de sortie (142) qui fournit une lumière de sortie dans un environnement ambiant. Les première et seconde parois (150-i, 150-o) sont conçues pour propager la lumière depuis l'ouverture d'entrée (122) vers l'ouverture de sortie (142).
