Title (EN) CIRCULAR FLASHLIGHT EXTENSION
(FR) PROLONGATEUR CIRCULAIRE POUR LAMPE-ECLAIR
Abstract:
(EN) The circular extension (1) to diffuse flashlight consists of a double hollow cylinder with the inlet opening (5) in the back wall (3) to mount the head (6) of an external flashlight (15) on a camera (16) in the direction of the central axis (7) of the extension (1). Opposite to the inlet opening (5) there are at least two reflecting surfaces (9, 10) reflecting the light into the extension (1) on both sides of the inlet opening (5). The light goes through the diffuser (4) outside. A light-guiding ring (11) inside the extension (1) improves the transmission of light. A size adaptor (20) on the inlet opening (5) enables its universal use for various flashlights (15).
(FR) Le prolongateur circulaire (1) pour lampe-éclair selon la présente invention comprend un cylindre double et creux pourvu d'une ouverture d'entrée (5) prévue dans la paroi arrière (3) en vue d'installer la tête (6) d'une lampe-éclair (15) sur un appareil photographique (16) dans le sens de l'axe central (7) du prolongateur (1). En face de l'ouverture d'entrée (5) se situent au moins deux surfaces réfléchissantes (9, 10) qui renvoient la lumière dans le prolongateur (1) sur les deux côtés de l'ouverture d'entrée (5). La lumière traverse le diffuseur (4) et sort à l'extérieur. Un anneau de guidage de la lumière (11) situé à l'intérieur du prolongateur (1) améliore la transmission de la lumière. Un adaptateur (20) pour la taille situé sur l'ouverture d'entrée (5) permet de l'utiliser avec diverses lampes-éclairs (15).
