  • Patent number: 5789849
    Abstract: A fluorescent lamp, particularly of annular shape, with a tube-shaped disrge vessel has a base with contact pins, in which the two ends of the vessel face each other. The contact pins are essentially arranged in the annular plane of the lamp on both sides of the base. The mount belonging thereto has a U-shaped profile. The arms of the mount are provided with recesses for taking up and making contact with the contact pins of the base. This makes possible a linear motion when inserting the base into the mount. Retaining springs on the mount and recesses on the base belonging thereto make possible a locking of the base with the mount. Another advantage is the small structural height of the lamp including the mount.

  • Patent number: 5491374
    Abstract: To ensure contact of axially bent-back current supply leads, extending over plate-like base terminals of an elongated fluorescent lamp, and ensure electrical connection between the bent-over or bent-back portions with socket terminal springs (9a, 9b), in spite of misalignment of the bases (3) at two opposite ends of the fluorescent lamp, the junctions or corners (1118) between the narrow wall portions (18a, 18b) and wide side wall portions (11a, 11b; 12a, 12b; 13a, 13b) of the end portion (4) of the base are set back from the position in a theoretical geometric rectangle or parallelogram to form relieved wide side wall portions. The relieved side wall portions extend axially over essentially the entire length of the end portion (4) of the base.
