  • Double latch snap lock base for annular fluorescent lamps
    Patent number: 4468071
    Abstract: An improved plastic base for annular fluorescent lamps is disclosed having two semicylindrical parts which can be assembled together reliably in high speed manufacture to provide an assembled lamp less prone to failure during use. The first part includes double latch means together with locking pins and mates with a second part having means to receive these latching and locking elements when the parts are joined together. Other elements are also located on both parts to limit rotation of the assembled base about the annular lamp. Tapered conductive contact ends can also be used to facilitate high speed manufacture when inserted into tapered openings in the lamp base.

  • Photoflash lamp array having conductive reflector
    Patent number: 4104706
    Abstract: A photoflash lamp array comprising a plurality of flash lamps having lead-in wires connected to a circuit board, and a reflector unit positioned between the lamps and the circuit board. The reflector unit is made of plastic having an electrically conductive reflecting coating on its front surface, and the reflector unit is shaped to provide openings so that the conductive coating is adjacent to or touching electrical ground areas of circuitry on the circuit board, whereby the reflector unit functions to dissipate electrostatic charges thus preventing accidental flashing of lamps.

  • Photoflash lamp array having conductive reflector
    Patent number: 4060721
    Abstract: A photoflash lamp array comprising a plurality of flash lamps having lead-in wires connected to a circuit board, and a reflector unit positioned between the lamps and the circuit board. The reflector unit is made of plastic provided with an electrically conductive reflecting coating on its front surface, and is further provided with an integral tab member having a surface exposed to the front of the reflector unit, which surface is coated with said conductive coating, the tab being bent over so that its coated surface faces the circuit board and is in contact with an electrical ground area of the circuit board, whereby the conductive coating of the reflector unit is connected to electrical ground and functions to dissipate electrostatic charges thus preventing accidental flashing of lamps.
