Illumination device with a connector having a retainer with a rotary member and elastic pieces

An illumination device comprising:

• 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;
• first and second connectors arranged at opposite ends of the base for selectively receiving one of a fluorescent tube or an LED tube, the fluorescent tube comprising two conductive pins arranged on one end thereof and another two conductive pins arranged on an opposite end thereof, the LED tube comprising a conductive pin and an insulated pin being arranged on each end thereof, and the conductive pins arranged on opposite ends of the LED tube being diagonally opposite to each other;
• wherein the first connector comprises:
• a retainer defining a though hole;
• a rotary member rotatably received in the through hole, and defining a first groove to receive 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, the first and second elastic pieces electrically connecting with the LED tube drive circuit board, and the first and third elastic piece electrically connecting with the fluorescent tube drive circuit board;
• wherein the second connector comprises:
• a retainer;
• and
• four elastic pieces comprising a fourth elastic piece, a fifth elastic piece, a sixth elastic piece and a seventh elastic piece received in the retainer of the second connector, in which the fifth and sixth elastic pieces electrically connect with a negative terminal of a power source and the seventh elastic piece electrically connects with a starter which is in turn electrically connected with the third elastic piece of the first connector, the first elastic piece being electrically connected with a positive terminal of the power source via a ballast and the second elastic piece being electrically connected with the positive terminal directly;
• wherein when the rotary member of the first connector is 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 of the first connector, and the two pins on the opposite end of one of the two tubes stay in contact with the fourth elastic piece and the fifth elastic piece, respectively, and wherein when the one of the tubes is the LED tube, and the two pines on the opposite ends of the LED tube and connecting with the second and fifth terminals are the conductive pines, the LED tube is driven by the LED tube drive circuit board;
• and
• when the rotary member of the first connector is rotated to a second position, the two pins on the one end of one of the tubes stay in contact with the second elastic piece and the third elastic piece, respectively, and the two pins on the opposite end of one of the tubes stay in contact with the sixth elastic piece and the seventh elastic piece, respectively, and wherein when the one of the tubes is the fluorescent tube, the fluorescent tube is driven by the fluorescent tube drive circuit board.
