Title (EN) DIFFUSER WITH UPLIGHT
(FR) DIFFUSEUR DOTÉ D'UN ÉCLAIRAGE VERS LE HAUT
Abstract:
(EN) The present disclosure is directed to an apparatus. The apparatus includes a light diffusion portion comprising a same shape and approximately a same two dimensional size as a bottom surface of a light source, a light redirection device coupled to a perimeter of the light diffusion portion, wherein the light redirection device redirects a first portion of light emitted from a light source in a direction opposite a second portion of light emitted from the light source that travels through the light diffusion portion, and at least one mechanical coupling member coupled to the light redirection device, wherein the at least one mechanical coupling member is to connect to a corresponding portion of the light source.
(FR) La présente invention concerne un appareil. L'appareil comprend une partie de diffusion de lumière comprenant une même forme et approximativement une même taille bidimensionnelle qu'une surface inférieure d'une source de lumière, un dispositif de redirection de lumière couplé à un périmètre de la partie de diffusion de lumière, le dispositif de redirection de lumière redirigeant une première partie de la lumière émise à partir d'une source de lumière dans une direction opposée à une seconde partie de la lumière émise à partir de la source de lumière qui se déplace à travers la partie de diffusion de lumière, et au moins un élément de couplage mécanique couplé au dispositif de redirection de lumière, ledit au moins un élément de couplage mécanique étant destiné à être relié à une partie correspondante de la source de lumière.
