The invention relates to a lighting device (1) comprising a substrate (2), a non-transparent spacer (4) sealingly connected to the substrate (2), an opening in the spacer element ( 4) which is opposed to the substrate (2), a luminescent element (3) which is arranged under the spacer (4) and under the opening and which is sealingly connected to the substrate (2). The invention is characterized in that the opening in the spacer (4) is sealingly closed by an optical element (5) of a glass-like material, the volume of which contains at least one substance luminescent and which as such represents a composite material based on luminescent glass. |
