An ultraviolet-producing means is positioned so as to irradiate the fill-containing envelope of the discharge lamp. The ultraviolet-producing means is excited by microwave energy which is extracted from means which couples microwave energy from the microwave source to the fill-containing envelope of the discharge lamp. | |
