Abstract

L'invention concerne un réflecteur et une lampe à DEL pour éclairage public ainsi équipée, et plus précisément un réflecteur réfléchissant la lumière émise par des DEL, et une lampe à DEL pour éclairage public ainsi équipée. Ladite lampe comprend un corps disposé sur un cadre horizontal; et au moins un substrat soutenu par le corps; un réflecteur prévu pour protéger au moins une partie d'une surface frontale du substrat, et ayant une pluralité de trous pour réfléchir la lumière; et une pluralité de DEL ayant un élément de connexion disposé sur la surface frontale du substrat de façon à être intercalé entre le réflecteur et la surface frontale du substrat et une partie luminescente connectée à la partie de connexion de manière à pénétrer dans le réflecteur via des trous du réflecteur. La lampe à DEL est capable de diffuser de la lumière à la périphérie et d'éviter les pertes engendrées par l'absorption de la lumière, ce qui en améliore les propriétés d'éclairage et de diffusion.
