    • A light-emitting electronic textile for arrangement under a covering textile (5) for providing light-output through the covering textile (5), the light-emitting electronic textile comprising a flexible component carrier (2) having a plurality of light-sources (3) arranged thereon; and a flexible light-spreading layer (4) arranged on the flexible component carrier (2) for distancing the light-sources (3) from the covering textile (5) and for allowing light emitted by the light-sources (3) to spread before hitting the covering textile (5). The light- spreading layer (4) comprises a first flexible sheet (8) of a first material having a first optical transmittance, and a plurality of cavities (9a-c; 11) formed in the first flexible sheet (8), wherein each of the cavities (9a-c; 11) is empty, or contains a second material (12) having a second optical transmittance being higher than the first optical transmittance. Hereby, the textile-like mechanical properties of the light-emitting electronic textile can be improved, while enabling a reduction of the loss of light due to absorption in the light-spreading layer.
    • 一种用于布置在覆盖纺织品(5)下方的用于通过覆盖织物(5)提供光输出的发光电子织物,所述发光电子织物包括具有多个光源的柔性部件载体(2) 3) 以及布置在所述柔性部件载体(2)上的用于使所述光源(3)与所述覆盖织物(5)间隔开并且用于允许由所述光源(3)发射的光扩散的柔性扩散层(4) 在打包覆织物(5)之前。 光扩散层(4)包括具有第一光透射率的第一材料的第一柔性片(8)和形成在第一柔性片(8)中的多个空腔(9a-c; 11),其中每个 的空腔(9a-c; 11)是空的,或包含具有高于第一光透射率的第二光透射率的第二材料(12)。 因此,可以提高发光电子织物的织物状机械性能,同时能够减少由于在光扩散层中的吸收引起的光的损失。
