Yet the shortcoming of known techniques is following.

1, this external module Assembly Action is complicated, and assembly cost is higher.

2, welding quality is difficult to the naked eye judge, therefore might produce tiny crack, and if the welding personnel level also influences welding quality easily uneven.

3, general LED fluorescent tube still prolongs with the holder structure of commonly using, and then the LED fluorescent tube inserts when commonly using the socket of holder structure, turn 90 degrees beginning ability energized because of need revolve, and so will make the shadow surface of LED fluorescent tube also depart from 90 degree, makes LED fluorescent tube below one side can't obtain illumination.

The utility model content

The technical problem that the utility model solved is promptly providing the design that can see through fluorescent tube, circuit board and end cap; Let the user utilize simple grafting action can form the contact conducting; Circuit board and fluorescent tube are had to revolve the effect that different irradiating angles are adjusted in three-sixth turn, and then increase whole practicality.

The technical scheme of the utility model is: a kind of lamp tube structure of light-emitting diode includes: a fluorescent tube, and this fluorescent tube inboard is provided with a locating slot; Two end caps are arranged at this fluorescent tube two ends respectively, and each end cap is provided with two electric terminals, then is respectively equipped with a conducting terminal in each end cap inboard, and this conducting terminal is connected with this electric terminal; And a circuit board, being arranged in this locating slot, these circuit board two ends are provided with a socket, can supply the conducting terminal of each end cap to peg graft and form conducting.

This fluorescent tube lower edge is formed with plurality of radiating fins.

The combination of this end cap and fluorescent tube is come chimeric fixing with fin circular groove mode.

This electric terminal and this conducting terminal are to be made into integration.

The beneficial effect of the utility model is: the light-emitting diode lamp tube of the utility model includes: a fluorescent tube, two end caps and a circuit board; This fluorescent tube inboard is provided with a locating slot can supply to be provided with circuit board; Each end cap is arranged at this fluorescent tube two ends respectively, and is respectively equipped with two electric terminals, then is respectively equipped with a conducting terminal in each end cap inboard; This conducting terminal is connected with this electric terminal, and these circuit board two ends are provided with a socket; By this; The conducting terminal that sees through each end cap directly is plugged in this socket and forms the contact conducting, with conduct power, makes to have simple and easy assembling; And all replaceable maintenance external member of common people; Reach electrical joint and have the rotatable structure of circling round of 360 degree, can constitute fluorescent tube and circuit board and come the revolution of corresponding orientation, with the demand irradiating angle of adjustment use.
