  • Patent number: 6346767
    Abstract: A lamp has an electrically insulating, light-transmitting, preferably lead-free envelope with a base end and contains a light source. At least two electrical lead-ins are connected to the light source and exit the envelope. A base is affixed to the base end, the base having first and second electrically conductive portions separated by an electrically insulating portion. One of the electrical lead-ins is electrically connected to the first electrically conductive portion and another of the electrically conductive lead-ins is electrically connected to the second electrically conductive portion. The base is non-rotationally mounted to the base end of the lamp by a locking clip affixed to the first electrically conductive portion by mechanical means and affixed to the base by chemical means.

  • Patent number: 6323588
    Abstract: A locking clip 10 for fixing a base to an end of a glass bulb. The locking clip 10 has a body 12 with a first portion 14, a middle portion 16 and an end portion 18. The middle portion 16 is scyphate, i.e., cup-shaped, and defines a plane, 20 (FIG. 2). The first portion 14 extends away from plane 20 in a given direction by an angle &agr;, which, in a preferred embodiment, is about 5 degrees. The end portion 18 is connected to the middle portion 16 by a reentrant section 22 and extends away from the plane 20 by an angle &bgr; in a direction opposite to the given direction. In a preferred embodiment angle &bgr; is preferably about 20 degrees. In a still more preferred embodiment the included angle between first portion 14 and end portion 18 is between 25 and 35 degrees. A centrally located aperture 24 is provided in the reentrant section 22 to aid in the subsequent bending of the end portion 18 at the final welding.
