ABSTRACT:
An improved germicidal lamp of the type containing mercury, having a ceramic base, and disposed in, and preventing contact with, a transparent quartz sleeve to prevent formation of a cold spot in the germicidal lamp caused by an undesirable thermal transfer between the lamp and the sleeve and which causes condensation of the mercury at the cold spot in the germicidal lamp. The improvement includes the ceramic base having a circumferential groove therearound, and a thermally insulating ring siting in the circumferential groove of the ceramic base so as to prevent the ceramic base from contacting the sleeve to prevent formation of the cold spot in the germicidal lamp caused by the undesirable thermal transfer between the lamp and the sleeve and prevent the condensation of the mercury at the cold spot in the germicidal lamp.
