The present invention discloses a transparent emissive window element (100, 700), i.e. a transparent window element capable of emitting light. According to a first aspect of the present invention, the window element (100) comprises a light guide (110) for guiding light emitted from at least one light source (150) by total internal reflection, a glass pane (120) arranged in proximity to the light guide and scattering structures (130) for coupling the light out of the light guide. The scattering structures (130) are sandwiched between the light guide (110) and the glass pane (120) such that spacing areas (140), at which optical contact between the light guide and the glass pane is prevented, are formed between the scattering structures. According to a second aspect of the present invention, the window element (700) comprises at least one light source (750), a glass pane (710) and refracting structures (740) arranged at a surface of the glass pane (710) such that light emitted from the light source is refracted by the refracting structures towards the glass pane and directed out of the window element (700). |
