Abstract

L'invention se rapporte à un dispositif d'ombrage en réseau destiné à réfracter un faisceau dans un boîtier de lampe. Le dispositif d'ombrage en réseau est placé entre un tube de lampe et une plaque de lumière uniforme, il s'agit d'un corps de réfraction transparent ou par opacité. Le corps de réfraction comporte une face symétrique (4), la face symétrique (4) et l'axe central du tube de lampe se trouvent à l'intérieur d'un même plan. Une surface du corps de réfraction, qui fait face au tube de lampe, est une surface de réfraction qui est convexe et l'autre surface, qui fait face à la plaque de lumière uniforme, est une surface de réflexion. La largeur transversale du corps de réfraction est plus petite que celle du tube de lampe. Lors de l'utilisation de l'invention, le faisceau qui est émis depuis le tube de lampe jusqu'à la surface de réfraction est réfléchi par la surface de réfraction vers un couvercle du boîtier de la lampe et une partie du faisceau est ensuite réfléchie par le couvercle vers la plaque de lumière uniforme à distance du tube de lampe. Le faisceau qui est dirigé depuis le tube de lampe vers la plaque de lumière uniforme est réfléchi par la plaque de lumière uniforme vers la surface de réfraction du corps de réfraction et il est ensuite réfléchi par le corps de réfraction vers la plaque de lumière uniforme. Ainsi, l'invention peut, non seulement, augmenter l'éclairage de la plaque de lumière uniforme, mais également rendre uniforme l'éclairage, réduire en outre le volume du boîtier de la lampe et améliorer la disponibilité du faisceau.
