  • Patent number: 7521641
    Abstract: A lamp socket with multiple switches has a casing, a switching contact assembly, a stem assembly, an electric tab assembly, a photo switch, a first electric connector and a second electric connector. The switching contact assembly is mounted in the casing and around the stem assembly. The stem assembly has multiple pans. The electric tab assembly is mounted on two of the multiple pans and selectively connects the switching contact assembly. The first electric connector and the second electric connector are connected electrically to the photo switch. The electric tab assembly connects the switching contact assembly via turning the stem assembly to turn on or off a three-way bulb. Furthermore, the lamp socket turns on a three-way bulb based on ambient light.

  • Patent number: 7478926
    Abstract: A lamp socket has a casing, a switching contact assembly, a stem assembly, an electric tab, a photo switch, a first electric connector and a second electric connector. The switching contact assembly is mounted in the casing and around the stem assembly. The stem assembly has a pawl. The pawl has multiple surfaces. The electric tab is mounted on two of the surfaces of the pawl and selectively contacts the switching contact assembly. The first electric connector and the second electric connector are connected electrically to the photo switch. The contact between the electric tab and the switching contact assembly switches via turning the stem assembly to turn on or off two lights. Furthermore, the lamp socket turns on one of the lights based on ambient light.

  • Patent number: 6439746
    Abstract: A lampshade for a table lamp has a top plate, multiple panel frames and multiple shade panels. Each panel frame has a panel support and at least one panel clip to hold one of the shade panels. The top plate has an elongated hole to engage with a hook formed on each panel frame. A through hole is defined in the panel support of each panel frame. A threaded stud extends from each panel frame and through the through hole in the adjacent panel frame. A nut is screwed onto each threaded stud to detachably connect adjacent panel frames. Consequently, the panel frames can be disassembled from the top plate, and the panel frames are detachable. The lampshade can be disassembled into multiple parts. The packaging and storage sizes of the lampshade are reduced. To transport or to store the lampshade becomes more convenient.
