The conventional lamp tube i is on the group |, the conductive plug i3i_ connection of the conductive electrode 13 must be erected parallel to the light-emitting diode 15 The circuit board Μ, when the angle of the installation between the two is different, it will affect the angle behind the light-emitting diode b.叩 知 knows to have illuminating - ~ a B i you 5 and the end cap 12 and the tube body U are mutually rotatable circular, and the end cap 12, the tube body 11 and the circuit board 也 also line The bit design is only fixed with glue. Therefore, it is difficult to make the circuit board 14 accurately parallel to the connection of the conductive plunger 131 during assembly. Even when assembling, the components have been accurately matched. When the prefabrication is set between the conductive sockets 1 , the assembly needs to move the lamp tube in the process of rotating and assembling, in order to return to the square body of the knot, it is not strong, and it is easy to cause relative rotation between the components. When the relative rotation between the end cover 12 and the circuit board 14 occurs, the conductive plug: cannot accurately correspond to the circuit board 14, and the light-emitting diode u cannot be properly irradiated in a predetermined direction. SUMMARY OF THE INVENTION 200928193 - The purpose of the invention is to provide a lamp having a light-emitting diode that is easy to position when assembled, and that does not rotate with each other after assembly to ensure better assembly quality.

The end cover 51 has a base wall 511 abutting against the outer end surface of the pipe wall 32 of the pipe body 3, and a base wall 511 toward the open end 311. Extends into the snap ring wall 512. The collar wall 512 has two anti-rotation slots 513 for the limiting bar 33 of the tube body 3 to extend into the latch, and the conductive electrode 52 has two conductive plugs that can be inserted into the conductive socket 2 A conductive plunger 521 in the hole 21. When the lamp tube of the embodiment is assembled, the light emitting diode 42 is mounted under the assembly surface 412 of the circuit board 41, and then the circuit board 41 is inserted into the corresponding limiting slot 332 of the pipe body 3.
