A lighting device having a plurality of light sources includes several superimposed layers. The superimposed layers include a first and a second electrically conductive layer, which are designed so as to create an alternating electrical field between the layers. The superimposed layers also have an electrically insulating layer between the electrically conductive layers and a luminescent layer between the electrically conductive layers. Electroluminescent material is arranged within the luminescent layer in several adjacent and spatially separated regions, each region forming a light source. As a result, a simulated starry sky may be provided when the lighting device is used with an aircraft interior trim panel.
