  • Patent number: 11183380
    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.

  • Patent number: 10366875
    Abstract: A UV radiator unit includes an elongated gas discharge lamp with an essentially cylindrical UV transparent lamp body with sealed ends, which encloses a gas volume. The lamp body defines a longitudinal axis and has an outer diameter. A UV transparent sleeve tube with an inner diameter, which surrounds the lamp body and wherein the inner diameter is larger than the outer diameter of the lamp body. At least one damping ring is interposed between the lamp body and the sleeve tube. The damping ring includes a first side element, a second side element and at least one connecting portion. An axial distance is provided between the first side element and the second side element. The at least one connecting portion physically connects the first side element and the second side element.
