  • Illumination device with a connector having a retainer with a rotary member and elastic pieces
    Patent number: 8371867
    Abstract: An illumination device includes a light tube holder including two connectors for receiving either a light-emitting diode (LED) tube or a fluorescent tube. One of the connectors includes a rotary member rotatably received in a through hole defined in a retainer, and three conductive elastic pieces positioned in the retainer around the through hole. One conductive piece is electrically connected to an LED tube drive circuit board and a fluorescent tube drive circuit board, and the other two conductive pieces are electrically connected to the LED and fluorescent tube drive circuit boards, respectively. The rotary member can be rotated to first and second positions, wherein at the first position, the LED tube can be activated, and at the second position the fluorescent tube can be activated.
