Title (EN) LUMINAIRE WITH LIGHT GUIDE.
(FR) LUMINAIRE À GUIDE DE LUMIÈRE
Abstract:
(EN) Disclosed is a luminaire (1) comprising a circular light guide (10), the light guide comprising an edge portion (11) in between a first major surface (15) and a second major surface (17), at least part (16) of the first major surface guide tapering in a direction away from said edge portion; a plurality of solid state lighting elements (40) arranged along said edge portion; and a plurality of outcoupling elements (30) arranged in a pattern on the second major surface of the circular light guide. The luminaire (1) may further include a controller (50) for individually controlling the solid state lighting elements (40) such as to configure the luminous output, e.g. the beam profile, of the luminaire.
(FR) La présente invention concerne un luminaire (1) comprenant un guide de lumière circulaire (10), le guide de lumière comprenant une partie de bord (11) entre une première surface principale (15) et une seconde surface principale (17), au moins une partie (16) du premier guide de surface principal s'effilant dans une direction éloignée de ladite partie de bord; une pluralité d'éléments d'éclairage semi-conducteurs (40) disposée le long de ladite partie de bord; et une pluralité d'éléments de couplage de sortie (30) disposée selon un motif sur la seconde surface principale du guide de lumière circulaire. Le luminaire (1) peut en outre comporter un dispositif de commande (50) permettant de commander individuellement les éléments d'éclairage semi-conducteurs (40) de manière à former la sortie lumineuse, par exemple le profil de faisceau, du luminaire.
