Title (EN) A LED LIGHTING DEVICE WITH AN ADJUSTABLE SPATIAL DISTRIBUTION OF THE EMITTED LIGHT
(FR) DISPOSITIF D'ÉCLAIRAGE À LED À RÉPARTITION SPATIALE AJUSTABLE DE LA LUMIÈRE ÉMISE
Abstract: front page image
(EN)The present invention relates to a lighting device (1) that comprises a first light source (2) comprising one or more LED devices (21). At least a deformable reflective element (3) is optically coupled to said first light source, so as to receive light from said first light source, said reflective structure comprising at least a first portion (31) having a reflective surface (310) that reflects at least partially the light (L1) received from said first light source, and a second portion (32) that is solidly coupled to said first portion. Driving means (4) are operatively coupled to said second portion (32), which induce a deformation of said second portion that in turn causes a deformation of the reflective surface (310) of said first portion. The position of the focus point (F) of the light (L2) reflected by said reflective surface can thus be varied in a controlled manner.
(FR)La présente invention se rapporte à un dispositif d'éclairage (1) qui comprend une première source de lumière (2) comprenant un ou plusieurs dispositifs à LED (21). Au moins un élément réfléchissant déformable (3) est optiquement couplé à ladite première source de lumière, de manière à recevoir la lumière provenant de ladite première source de lumière, ladite structure réfléchissante comprenant au moins une première partie (31) ayant une surface réfléchissante (310) qui réfléchit au moins partiellement la lumière (L1) reçue en provenance de ladite première source de lumière, et une seconde partie (32) qui est solidement couplée à ladite première partie. Un moyen d'entraînement (4) est fonctionnellement couplé à ladite seconde partie (32), ce qui provoque une déformation de ladite seconde partie qui à son tour entraîne une déformation de la surface réfléchissante (310) de ladite première partie. La position du point de concentration (F) de la lumière (L2) réfléchie par ladite surface réfléchissante peut ainsi varier d'une manière commandée.
