Abstract

L"invention concerne une lampe DEL dotée d"une cavité réfléchissante et comprenant un écran, une colonne principale formée d"un faisceau de DEL et un support. La colonne principale DEL est installée sur l"écran et la DEL est connectée à une alimentation spécifique. La lampe est caractérisée en ce qu"une cavité réfléchissante est définie dans l"écran. La cavité réfléchissante est composée d"une partie de paroi interne d"écran et du support, d"un film réfléchissant formé sur la surface de la cavité réfléchissante. Par ailleurs, la cavité réfléchissante peut être composée d"une partie d"un corps réfléchissant conique placé in situ assemblé au support se trouvant dans l"écran et un film réfléchissant est défini sur la surface du corps réfléchissant conique. Toute la lumière émise par la DEL est orientée vers la même direction de manière à être plus centralisée, à renforcer la luminosité et à assurer un éclairage plus loin.
