Title
(EN) LUMINAIRE HAVING A MOCK LIGHT SOURCE
(FR) APPAREIL D'ECLAIRAGE DOTE D'UNE SOURCE DE LUMIERE FACTICE
Abstract
(EN) A luminaire (11) has a light reduction cover element (37) below and in proximity to the active light source (17) of the luminaire to simulate a larger light source having a lower surface brightness which is exposed through the luminaire's down light opening (27). For example, where the luminaire has a high output T5 lamp (17), the light reduction cover element can be in the form of a substantially semi-cylindrical opal diffuser cover strip (17) sized to simulate a T8 or T12 lamp. An opal diffuser cover strip (65) having two side-by-side arcuate portions (85a, 85b) joined at their interior edges (83a, 83b) to form an opaque center ridge (87) can be positioned under two side-by-side T5 lamps (63a, 63b) to simulate side-by-side T8 or T12 lamps.
(FR) La présente invention concerne un appareil d'éclairage (11) présentant un élément de couverture de réduction de lumière (37) se trouvant en-dessous et à proximité d'une source de lumière active (17) de l'appareil d'éclairage permettant de simuler une source de lumière plus importante ayant une luminance inférieure qui est visible par l'ouverture de lumière inférieure (27) de l'appareil d'éclairage. Par exemple, lorsque l'appareil d'éclairage possède une lampe T5 à grand rendement (17), l'élément de couverture de réduction de lumière peut se présenter sous la forme d'une bande de couverture à diffuseur opale essentiellement semi-cylindrique (17) conçue pour simuler une lampe T8 ou T12. Une bande de couverture à diffuseur opale (65) ayant deux parties arquées juxtaposées (85a, 85b) reliées au niveau de leurs bords intérieurs (83a, 83b) pour former une arête centrale opaque (87) peut être placée en-dessous de deux lampes T5 juxtaposées (63a, 63b) afin de simuler des lampes T8 ou T12 juxtaposées.
