Title
(EN) LIGHT SUPPLEMENTATION DEVICE
(FR) DISPOSITIF DE SUPPLÉMENTATION DE LUMIÈRE
(ZH) 一种补光装置
Abstract
(EN)
Disclosed is a light supplementation device (100), comprising a mounting plate (6) as well as a first lamp bank (1) and a second lamp bank (2) disposed thereon. Light emitted from a first light emitting element (11) of the first lamp bank (1) exits from a first light-exiting surface (122) of a first prism (12), the first prism (12) having a first prism angle. Light emitted from a second light emitting element (21) of the second lamp bank (2) exits from a second light-exiting surface (222) of a second prism (22), the second prism (22) having a second prism angle. The first prism angle is different from the second prism angle such that light from the first lamp bank (1) and light from the second lamp bank (2) exit to different directions so as to supplement light for different ranges (51) of an area subject to light supplementation (5), thereby avoiding nonuniform brightness caused by light supplementation in a single direction. The mounting plate (6) realizes the combination and assembly of lamp banks with different light exiting directions, avoiding the complexity of respectively installing a plurality of lamp banks.
(FR)
L'invention concerne un dispositif de supplémentation de lumière (100) comprenant une plaque de montage (6) sur laquelle sont disposés un premier groupe de lampes (1) et un second groupe de lampes (2). La lumière émise par un premier élément électroluminescent (11) du premier groupe de lampes (1) sort d'une première surface de sortie de lumière (122) d'un premier prisme (12), le premier prisme (12) ayant un premier angle de prisme. La lumière émise par un second élément électroluminescent (21) du second groupe de lampes (2) sort d'une seconde surface de sortie de lumière (222) d'un second prisme (22), le second prisme (22) ayant un second angle de prisme. Le premier angle de prisme est différent du second angle de prisme de telle sorte que la lumière provenant du premier groupe de lampes (1) et la lumière provenant du second groupe de lampes (2) sortent dans des directions différentes de façon à compléter la lumière pour différentes plages (51) d'une zone soumise à une supplémentation de lumière (5), ce qui permet d'éviter une luminosité non uniforme provoquée par une supplémentation de lumière allant dans une seule direction. La plaque de montage (6) permet la combinaison et l'assemblage des groupes de lampes avec différentes directions de sortie de lumière, ce qui permet d'éviter la complexité de l'installation respective d'une pluralité de groupes de lampes.

一种补光装置(100),包括安装板(6)以及设于安装板(6)上的第一灯组(1)和第二灯组(2)。第一灯组(1)的第一发光元件(11)发出的光线从第一棱镜(12)的第一出光面(122)出射,第一棱镜(12)具有第一棱镜角。第二灯组(2)的第二发光元件(21)发出的光线从第二棱镜(22)的第二出光面(222)出射,第二棱镜(22)具有第二棱镜角。第一棱镜角和第二棱镜角不同,使得第一灯组(1)和第二灯组(2)的光线出射至不同的方向,能够为待补光区域(5)的不同范围(51)分别进行补光,避免了单一方向补光造成的亮度不均匀。借由安装板(6)同时实现多个出光方向的灯组的组合和装配,避免了多个灯组分别安装的复杂性。
