A lamp tube switch circuit supplies power to a selected LED/fluorescent lamp tube connected between first and second connectors and comprises a ballast and a starter. A power supply has positive and negative terminals. A switch module comprises first, second and third switches each having a first end connecting with the positive terminal, fourth and fifth switches each having a first end connecting with the negative terminal and a sixth switch having a first end connecting with the first connector. A button module has six buttons one of which is correspondent to the selected lamp tube. A control unit is connected to the button module, and functions to turn on and turn off the switches with a predetermined mode according the selected lamp tube.

Lamp tube switch circuit

An illumination device includes a light tube holder including two connectors for receiving either a light-emitting diode (LED) tube or a fluorescent tube. The connector 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 elastic piece is electrically connected to an LED tube drive circuit board, and the other two elastic piece are electrically connected to a fluorescent tube drive circuit board. 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. The LED tubes has two conductive pins at each end thereof. The LED tube can be mounted to the connectors regardless an orientation of the LED tube.
