Abstract

Cette invention concerne un dispositif d’éclairage atténué et compensé d’un corps de lampe avec lampe interne. Le dispositif est un corps opacifiant placé entre le tube de lampe et la plaque lumineuse du corps de lampe. Le corps opacifiant comprend un élément de réflexion de la lumière gauche, un élément de réflexion de la lumière droit et une unité d’atténuation de la lumière. La section de l’unité d’atténuation de la lumière forme un arc. Les éléments de réflexion de la lumière gauche et droit sont symétriques. Le plan de symétrie des deux éléments se trouve sur le même plan que la ligne centrale du tube de lampe. L’unité d’atténuation peut atténuer la lumière qu’elle reçoit afin de lui permettre de sortir par l’avant et les deux côtés du tube. Le dispositif peut ainsi réduire la perte de lumière de sorte à améliorer l’éclairement de la plaque lumineuse du corps de lampe. Les deux éléments de réflexion peuvent compenser la lumière au niveau de la partie de la plaque lumineuse éloignée du tube de lampe afin que l’éclairement soit uniforme.
