Abstract
A germicidal UV amalgam lamp with an elongated tubular lamp body and at least two filaments located on opposite ends of the lamp body. The lamp body is hermetically sealed with a pinch-sealed portion at both opposite ends, confining a gas volume in which a gas discharge can be produced along a discharge path between the filaments. Each filament has two electrical connectors, each including an internal portion connected to the filament and pinch-sealed into the lamp body. Each connector also includes an external portion located outside the lamp body for electrical connection of the lamp to a controlled power supply. The pinch-sealed portion bears a socket with an electrical temperature sensor and at least two electrical connections mounted to the socket. The at least two electrical connections of the temperature sensor are connected in parallel to the electrical connectors of the filament.
