Abstract

Appareil à unique source lumineuse linéaire combinée avec un unique réflecteur orientable dans l'axe focal duquel elle est placée, tous les dispositifs électriques nécessaires à la marche étant placés dans un boîtier commun. Le réflecteur est subdivisé longitudinalement en au moins deux, et de préférence en trois éléments 6', 6", 6"', le boîtier étant lui-même divisé en deux parties 1 et 2 et les éléments extrêmes du réflecteur sont toujours en position fixe par rapport à la partie supérieure du boîtier, tandis que l'élément médian 6" est orientable soit avec la partie supérieure 1, soit avec la partie inférieure 2 du boîtier, de manière à permettre soit un eclairage uniquement direct, soit un éclairage uniquement indirect, soit un éclairage mixte direct et indirect d'un objet. Application essentiellement aux caméras.Device with a single linear light source combined with a single orientable reflector in the focal axis of which it is placed, all the electrical devices necessary for walking being placed in a common box. The reflector is subdivided longitudinally into at least two, and preferably into three elements 6 ', 6 ", 6"', the housing itself being divided into two parts 1 and 2 and the end elements of the reflector are always in a fixed position relative to the upper part of the housing, while the middle element 6 "is adjustable either with the upper part 1, or with the lower part 2 of the housing, so as to allow either only direct lighting, or only indirect lighting , that is to say a mixed direct and indirect lighting of an object Application mainly to cameras.
