Title
(EN) LIGHT REFLECTION
(FR) RÉFLECTEUR DE LUMIÈRE
Abstract
(EN)
The description relates to devices that emit light from a light source. One example device can include a reflector extending along an arc and oriented in light receiving relation relative to the light source. The reflector can have a cross-sectional reflector profile taken transverse to the arc that includes a first portion having a swept profile that transitions to a second portion having a reverse swept profile.
(FR)
L'invention concerne des dispositifs qui émettent de la lumière à partir d'une source de lumière. Un dispositif donné à titre d'exemple peut comprendre un réflecteur s'étendant le long d'un arc et orienté dans une relation de réception de lumière par rapport à la source de lumière. Le réflecteur peut avoir un profil de réflecteur en coupe transversale pris transversalement à l'arc qui comprend une première partie ayant un profil balayé qui passe à une seconde partie ayant un profil balayé inverse.
