Title (EN) A LIGHT MODULE FOR PRODUCING LIGHT WITH A SCATTERING PATTERN THAT IS ELECTRICALLY VARIABLE AND USE THEREOF AS MULTIPLE PURPOSE LIGHT
(FR) MODULE D'ECLAIRAGE POUR LA PRODUCTION DE LUMIERE A MOTIF DE DIFFUSION ELECTRIQUEMENT VARIABLE ET SON UTILISATION EN TANT QU'ECLAIRAGE POLYVALENT
Abstract: front page image
(EN)The invention provides a light module (1) arranged to produce a beam of light (25) with a scattering pattern that is electrically variable. The module comprises a light source (2) arranged to provide a beam of light (5); and an electrically adjustable optical element (300) arranged to adjust the beam of light (5) from light source (2). The adjustable optical element comprises a first cell (10) with a first liquid crystal gel (11); optionally a polarization rotator (30); a second cell (20) with a second liquid crystal gel (21); and a unit 40 for applying a voltage across at least one of the first and second cells (10,20). Especially, the light module (1) provides a beam of light (25) with an anisotropic light distribution.
(FR)L'invention concerne un module d'éclairage (1) conçu pour produire un faisceau de lumière (25) pourvu d'un modèle de diffusion électriquement variable. Ce module comprend une source de lumière (2) destinée à engendrer un faisceau de lumière (5) et un élément optique ajustable électriquement (300) destiné à ajuster le faisceau de lumière (5) provenant de la source de lumière (2). Cet élément optique ajustable comporte une première cellule (10) avec un premier gel cristallin liquide (11), facultativement, un rotateur de polarisation (30), une seconde cellule (20) avec un second gel cristallin liquide (21), et une unité (40) conçue pour appliquer une tension à travers au moins une cellule parmi les première et seconde cellules (10, 20). Notamment, le module d'éclairage (1) permet d'engendrer un faisceau de lumière (25) avec une distribution de lumière anisotrope.
