    • A lamp (1) for lighting with an asymmetric light distribution comprises a casing (5) extending substantially along an axis (A), at least one light source (3) housed in the casing (5), and a substantially flat light guide panel (4) having a lateral edge (16), parallel to the axis (A) and facing the light source (3), for receiving the light emitted by the light source (3); the light guide panel (4) comprises a plate (10) made of substantially transparent material and an optical film (11) coupled to the plate (10); the optical film (11) is provided with an optical pattern (18) configured so as to extract the light, emitted by the light source (3), entering the plate (10) through the lateral edge (16), from the light guide panel (4) through a first face (13) of the plate (10), defining an emission surface (17) of the lamp (1); and it is configured so as to distribute the light with an asymmetric distribution in relation to the emission surface (17).
    • 一种用于以非对称光分布进行照明的灯(1)包括基本上沿着轴线(A)延伸的壳体(5),容纳在壳体(5)中的至少一个光源(3)以及基本上平坦的导光板 (4)具有平行于所述轴线(A)并面向所述光源(3)的侧边缘(16),用于接收由所述光源(3)发射的光; 所述导光板(4)包括由基本上透明的材料制成的板(10)和与所述板(10)耦合的光学膜(11); 所述光学膜(11)设置有光学图案(18),所述光学图案(18)被配置为提取由所述光源(3)发射的,通过所述侧边缘(16)进入所述板(10)的光从所述光导 面板(4)穿过所述板(10)的第一面(13),限定所述灯(1)的发射表面(17); 并且被配置为相对于发射表面(17)以不对称分布分布光。
