Title (EN) A LUMINAIRE COMPRISING A FIXTURE AND AT LEAST ONE LIGHTING ELEMENT, AS WELL AS SUCH A FIXTURE
(FR) LUMINAIRE COMPORTANT UN SUPPORT ET AU MOINS UN ÉLÉMENT D'ÉCLAIRAGE, ET SUPPORT
Abstract: front page image
(EN)A luminaire (1, 21, 31, 41, 51) comprises a fixture (2, 22, 32, 42, 52) and at least one lighting element (29). The fixture (2, 22, 32, 42, 52) is suspendible from a ceiling above a working area, wherein, in use, a side of the fixture (2, 22, 32, 42, 52) is directed towards the working area. On said side of the fixture (2, 22, 32, 42, 52),the fixture (2, 22, 32, 42, 52) comprises a sound reflecting element at least near a central region of the fixture (2, 22, 32, 42, 52) and a sound absorbing element (6, 26, 36, 46, 56) at least near the periphery (5, 25, 35, 45, 55) of the fixture (2, 22,32, 42, 52). Projected on the working area, the surface of the sound reflecting element is in the range of 40 to 80 percent of the total projected surface of the fixture on the working area, whilst the surface of the sound absorbing element (6, 26, 36, 46, 56) is in the range of 60 to 20 percent of the total projected surface of the fixture on the working area.
(FR)L'invention concerne un luminaire (1, 21, 31, 41, 51) comportant un support (2, 22, 32, 42, 52) et au moins un élément (29) d'éclairage. Le support (2, 22, 32, 42, 52) peut être suspendu à un plafond au-dessus d'une zone de travail et est caractérisé en ce qu'en cours d'utilisation, un côté du support (2, 22, 32, 42, 52) est dirigé vers la zone de travail. Sur ledit côté du support (2, 22, 32, 42, 52),le support (2, 22, 32, 42, 52) comporte un élément réfléchissant le son au moins près d'une région centrale du support (2, 22, 32, 42, 52) et un élément (6, 26, 36, 46, 56) absorbant le son au moins près de la périphérie (5, 25, 35, 45, 55) du support (2, 22, 32, 42, 52). Projetée sur la zone de travail, la surface de l'élément réfléchissant le son se situe dans une plage de 40 à 80 pour cent de la surface totale projetée du support sur la zone de travail, tandis que la surface de l'élément (6, 26, 36, 46, 56) absorbant le son se situe dans une plage de 60 à 20 pour cent de la surface totale projetée du support sur la zone de travail.
