Patent ID: 8636377

Claim:
A light tube holder comprising: a base; a light-emitting diode (LED) tube drive circuit board mounted in the base; a fluorescent tube drive circuit board mounted in the base; a pair of connectors arranged at opposite ends of the base for selectively receiving one of a fluorescent tube comprising two pins at each end thereof, and an LED tube comprising two conductive pins at an end thereof and two insulating pins at an opposite end thereof; wherein each of the pair of connectors comprises: a retainer defining a though hole; a rotary member rotatably received in the through hole, and defining a first groove to receive the two pins on one end of one of the tubes; and three elastic pieces positioned in the retainer around the through hole, the three elastic pieces comprising a first elastic piece, a second elastic piece, and a third elastic piece electrically insulated from each other, wherein the first elastic piece is opposite to the second elastic piece and the third elastic piece, the first and second elastic pieces are respectively connected to the LED tube drive circuit board, and the first and third elastic pieces are respectively connected to the fluorescent tube drive circuit board; wherein when the rotary members of the pair of the connectors are rotated to a first position, the two pins on the one end of one of the tubes stay in contact with the first and second elastic pieces connected to the LED tube drive circuit board, and allow the tube to be driven by the LED tube drive circuit board when the tube is the LED tube; and when the rotary members of the pair of the connectors are rotated to a second position, the two pins on the one end of one of the tubes stay in contact with the first and third elastic pieces connected to the fluorescent tube drive circuit board, and allow the tube to be driven by the fluorescent tube drive circuit board when the tube is the fluorescent tube.
