DETAILED DESCRIPTION OF THE EMBODIMENTS OF THE INVENTION

(6) The lamp cap as shown in FIGS. 15, including an end closure 3, a cylinder body 10, pins 2, a press button 4, a spring 5, a row pin 6, a micro switch 7 and a printed circuit board 8, a pin 6, a spring 5, a micro switch 7 and a printed circuit board 8 are all set inside of the lamp cap, wherein the printed circuit board 8 and the micro switch 7, the row pin 6, and the pin 2 are electrically connected to the power source (not shown) of the lamp.

(7) The two ends of the cylinder body 10 are open, wherein one end is used to assembly the tube, the end closure 3 is inserted into the other end of the cylinder body 10 to sealingly close that end. The inner wall of the cylinder body 10 is provided with the rim 11 for position limiting purposes, the end closure 3 is inserted in the cylinder 10 and engages against the rim 11, which can control the position of the end closure. The rim 11 is provided with bolt holes to fix the end closure 3. After the end closure 3 is assembled into the cylinder body 10, using the bolt 1 installed within the bolt assembly hole 31 such that the bolt 1 passes through the circuit board 8 and screws into the bolt hole on the edge of the ring to complete the fixation of the end closure.

(8) The end closure 3 has an air vent 32 and a through hole 33 for the extrusion of the raised press button 4, two pin 2 also sets on the end closure 3 and connects to the printed circuit board 8 though the row pin 6, the through hole 33 is located between the two pins 2. The printed circuit board 8 is fixed inside of the end closure 3 through the screw 9.

(9) The position limiting board 41 is located on the press button 4 and the board prevents the press button from slippery from the through hole 33. The position limiting board a bit bigger in size than the through hole, one surface of the position limiting board has bumping points 42 and a steering bar 43. The bumping points 42 are used to trigger the micro switch 7, when the lamp is inserted into the lamp holder; the press button 4 is pressed back by resistance, which triggers the micro switch 8, which enables the electrical connection between the pin 2 and the power source. The printed circuit board 8 has steering holes; the press button 4 is guided to work through the cooperation between the steering bar 43 and the steering hole.

(10) In this practical embodiment, the two micro switches 7 are both parallelly and reversely arranged, correspond to the bumping points 42 alternately, in order to control electrical connecting between the two pins 2 and the power source at same time. In addition, two steering bar 43 respectively sets on two sides of the press-button 4 to keeps balance of pressure on the press button 4.

(11) The spring 5 is sleeved onto the steering bar 43, the two ends of the spring 5 respectively engage against the position liming board 41 and the printed circuit board 8. In other words, once the lamp cap is released from the lamp holder, press button 4 will be restored by action of the spring 5, causing the bumping points 42 to release its action on the micro switch 7, and to cut off electrical connection between the pins 2 and the power source.

(12) In another embodiment, both ends of the LED tube are arranged with the above structured cap. When the LED tube inserted in the socket, the press button 4 contracts inwardly after receiving resistance and engages with the micro switch 8 to connect the electrical circuit between the power source and the pins 2, so that the LED tube's electrical circuit is completed. When the LED tube is removed from the lamp-socket, the press button 4 reset to its original position, which relieves its action to the micro-switch 7, disconnecting the electrical circuit connection between the power source and the pin 2.

(13) The above description is only for the better implementation of the invention, the invention is not used to limit, all within the spirit and principle of the invention, any modification made by equivalent replacement, improvement, should be included in the scope of protection of the invention.
