Title (EN) PORTABLE COCKPIT LIGHT ASSEMBLY
(FR) ENSEMBLE D'ECLAIRAGE DE COCKPIT PORTABLE
Abstract:
(EN) A portable incandescent light assembly having a selectably interposable filter (17) is disclosed. The light assembly is particularly applicable to night vision situations for airplane pilots. The light assembly comprises a housing (13) in which a light source (65) and a filter (17) for filtering out infrared light are located. The light assembly further comprises a mechanism (11) for rotating the filter (17) within the housing (13) between a filtering position in which the filter (17) is disposed across a light output axis and a non-filtering position in which the filter (17) is disposed parallel to the light output axis.
(FR) Ensemble à lumière incandescente portable comportant un filtre sélectivement interposable (17). L'ensemble d'éclairage convient particulièrement à des situations de visibilité nocturne pour des pilotes d'aéronefs. L'ensemble d'éclairage comprend un logement (13) dans lequel se trouvent une source de lumière (64) et un filtre (17) pour filtrer et diffuser de la lumière infrarouge. L'ensemble d'éclairage comporte en outre un mécanisme (11) pour faire tourner le filtre (17) dans le logement (13) entre une position de filtrage dans laquelle le filtre (17) est disposé en travers de l'axe de sortie de la lumière et une position de non filtrage dans lquelle le filtre (17) est disposé parallèlement à l'axe de sortie de la lumière.
