Abstract:
Discharge lamp (1), suitable for operation by means of dielectrically impeded discharge, havinga discharge vessel (2) at least partially consisting of an electrically non-conductive material, electrodes (3-6) which are arranged on the wall (7) of the discharge vessel (2), at least one dielectric layer (61; 64) which covers at least a part of the electrodes (3-6) and, optionally, the discharge vessel wall (7) as well, a phosphor (63) and/or reflective layer (62) which covers the at least one dielectric layer (61; 61, 64), characterized in that at least the dielectric layer (61; 64) arranged essentially directly underneath the phosphor or reflective layer (62) consists of a glass solder whose viscosity variation as a function of temperature is irreversible.
