Abstract

La présente invention concerne une coupelle de réflexion, un appareil d'envoi de lumière, et un système de surveillance. La coupelle de réflexion (1) est pourvue d'une extrémité d'ouverture (2) et d'une extrémité restreinte (3) utilisées pour l'agencement d'une source de lumière. Une surface interne de la coupelle de réflexion (1) est principalement formée par des plans et des surfaces incurvées multiples, les plans et les surfaces incurvées servant à ajuster la lumière émise au moyen de la source de lumière et amenant la lumière à former un point lumineux trapézoïdal et à être projetée ensuite obliquement sur une zone d'éclairage rectangulaire. Une fois le point lumineux trapézoïdal projeté obliquement, le point lumineux trapézoïdal est étiré de sorte à former un point lumineux rectangulaire, et la forme du point lumineux rectangulaire est cohérente avec celle d'une chaussée, de sorte qu'un instantané vidéo puisse être pris sur un véhicule sur la chaussée. Par conséquent, la coupelle de réflexion peut être utilisée dans un système de surveillance du trafic.
