Abstract
A discharge lamp, suitable for operation by means of dielectrically impeded discharge, having electrodes arranged on the wall of the discharge vessel, has at least one dielectric layer which covers at least a part of the electrodes and, optionally, the discharge vessel wall as well. A phosphor and/or reflective layer is arranged on the at least one dielectric layer. According to the invention, at least the dielectric layer arranged directly underneath the phosphor or reflective layer consists of a glass solder whose viscosity variation as a function of temperature is irreversible, in particular of a sintered glass ceramic. This prevents this layer from re-melting during the fabrication process and thereby tearing the overlying porous reflective and/or phosphor layers.
