Abstract:
A method for operating a discharge lamp, a first, dielectrically impeded discharge and a second, dielectrically unimpeded discharge being generated in the discharge lamp, whereinby forming xenon excimers, UV radiation is generated by means of the first, dielectrically impeded discharge,the second, dielectrically unimpeded discharge is a xenon low-pressure discharge emitting UV radiation,the UV radiation generated by the two discharges is converted into visible light by means of one or more fluorescent materials (2;2'), andthe brightness of the discharge lamp is controlled by generating the dielectrically impeded discharge for the purpose of setting an undimmed state in the discharge lamp, and by generating the xenon low-pressure discharge for the purpose of setting a dimmed state in the discharge lamp.
