Abstract

Cette invention concerne un système d'éclairage comprenant un boîtier allongé; au moins une lampe avec LED située à l'intérieur du boîtier. Le système peut également comporter au moins une lentille placée adjacente à la LED d'éclairage. Il peut par ailleurs être équipé d'au moins un réflecteur situé dans le boîtier, ledit réflecteur comportant une première partie adjacente à la LED d'éclairage et une seconde partie couplée à la première partie, et disposée à l'extrémité distale opposée à la LED d'éclairage. La première partie et la seconde partie du réflecteur ont une forme sensiblement ronde.
