LIGHT EMITTING DEVICE

摘要

The invention relates to a light emitting device (10), comprising a stack of layers (15) of a substrate, with a basic layer (20), a first electrode layer (30) and a second electrode layer (40), wherein an organic light-emitting layer (50) is sandwiched between the first electrode layer (30) and the second electrode layer (40), the organic light-emitting layer (50) is emitting an artificial light (51), the basic layer (20) is covered by a retroreflective member (60), structured in a first section (61) and a second section (62), a plurality of retroreflective elements (70,70') are embedded in the first section (61), each retroreflective element (70,70') reflects an ambient light (80,80') falling onto a front side (65) of the retroreflective member (60) back in a direction of an origin of the ambient light (80,80'), the second section is transparent to the artificial light (51) falling onto a back side (66) of the retroreflective member (60).
