Abstract: Devices (10) comprise oblong light sources (1) that produce light for creating relatively bright zones (2) and obstacles (3) that block parts of the light for creating relatively dark zones (4). The relatively bright and relatively dark zones (2, 4) are separated by transitions (5). To soften these transitions (5), the obstacles (3) are provided with irregularities (6), such as curved edges or interruptions of straight lines of the obstacles (3) or texture. The oblong light source (1) may comprise a light unit in the form of a tube or an array of light units. The obstacle (3) may form part of a housing of the device (10). The relatively bright and relatively dark zones (2, 4) may be zones of a wall (7), a ceiling (8) or an object (9) outside the device (10) or may be zones in or at or of the device (10). The device (10) may be a video device such as a television receiver or a lighting device such as a lamp.
Abstract translation: 装置(10)包括产生用于产生相对明亮的区域(2)的光的椭圆形光源(1)和阻挡光的一部分以产生相对较暗的区域(4)的障碍物(3)。 相对较亮和相对较暗的区域(2,4)由转变(5)分开。 为了软化这些过渡(5),障碍物(3)设置有不规则物(6),例如障碍物(3)的直线或纹理的弯曲边缘或中断。 椭圆形光源(1)可以包括灯管形式的灯单元或灯单元阵列。 障碍物(3)可以形成装置(10)的壳体的一部分。 相对较亮和相对较暗的区域(2,4)可以是装置(10)外部的壁(7),天花板(8)或物体(9)的区域,或者可以是装置 (10)。 设备(10)可以是诸如电视接收器的视频设备或诸如灯的照明设备。
