  • Patent number: 10495264
    Abstract: A lamp includes a base with at least two electrical connecting elements. A bulb is rotatably mounted relative to the base. A light engine is arranged in the bulb with at least one light-emitting element and an electrically conductive substrate on which the light-emitting element is arranged. An electronic driver is connected to the electrically conductive substrate for activation of the light-emitting element. The base has a base sleeve in which the electronic driver is arranged. The electrically conductive substrate has a flexible connecting section between the electronic driver and the light-emitting element.

  • Patent number: 6774564
    Abstract: The invention relates to a method for capping an electric lamp which has a lamp cap with at least one thermoplastic synthetic cap part (21). In particular, the invention relates to a method for cementless capping of a compact fluorescent lamp. According to the invention, the lamp vessel (1) is sealed with the aid of the thermoplastic synthetic cap part (21) by heating sections (101, 102) of the lamp vessel (1) above the softening point and preferably above the melting point of the thermoplastic, and introducing them into constricted cutouts (210) in the thermoplastic synthetic cap part (21). The heated lamp vessel sections (101, 102) soften or melt and displace the synthetic material in the region of the constricted cutouts (210). The lamp vessel (1) is embedded in the set synthetic in a self-closed fashion after the polymer melt has been allowed to set.
