摘要：
The subject of the present invention is a system incorporating a DBD lamp (1), a dielectric barrier discharge (DBD-) lamp (1), and a phosphor coating (2) for use as luminescent coating in a dielectric barrier discharge (DBD-) lamp (1), especially in a mercury-free DBD-lamp, comprising several phosphor grains (3a) together forming a luminescent coating layer (3) for converting a primary discharge radiation into a wanted radiation, whereby the phosphor coating (2) comprises a protective coating layer (4) at least partly surrounding the luminescent coating layer (3) for minimizing degradation of the luminescent coating layer (3) during use in a DBD-lamp (1).
