    • The invention relates to a luminous panel (100) comprising: a transparent flat substrate (1) having an edge face (13), two main faces (11, 12) and a given thickness; at least one direct light region (31, 32) by means of a light source (2) associated with one of the main faces (12); a source (2) of visible and/or ultraviolet radiation, said radiation being guided by total reflections in the thickness of the substrate; and at least one extraction zone (41) for extracting the guided radiation, said extraction zone being associated with one of the main faces in order to form another luminous region (33) separate from the direct light region, and, on the same side as the main face (11) associated with the extraction zone (41), the direct light region (31) has a lower luminance than the luminance of the other luminous region (33).
    • 本发明涉及一种发光板(100),包括:具有边缘面(13),两个主面(11,12)和给定厚度的透明平面基板(1) 至少一个直接光区域(31,32),借助于与所述主面(12)中的一个相关联的光源(2); 可见光和/或紫外辐射源(2),所述辐射由衬底厚度的全反射引导; 以及至少一个用于提取被引导辐射的提取区域(41),所述提取区域与主面之一相关联,以形成与直接光区域分开的另一个发光区域(33),并且与 与所述提取区域(41)相关联的所述主面(11),所述直接光区域(31)的亮度比所述另一个发光区域(33)的亮度低。
