LED (Light emitting diode) lamp tube

The utility model discloses a LED (Light emitting diode) lamp tube, including the shell, set up a rectifier circuit, constant -current drive circuit and LED lamp pearl board in the shell, LED (Light emitting diode) lamp tube is still including setting up in the 3rd conductive terminal, the fourth conductive terminal of a conductive terminal, the 2nd conductive terminal and the other end of shell one end, LED (Light emitting diode) lamp tube still includes a switch circuit and first isolation trigger circuit, first isolation trigger circuit is used for making a switch circuit turns after the 3rd conductive terminal, the short circuit of fourth conductive terminal, and a rectifier circuit and the 3rd conductive terminal are connected. The utility model relates to a LED (Light emitting diode)lamp tube is through setting up switch circuit and keeping apart trigger circuit for LED (Light emitting diode) lamp tube because trigger circuit is just kept apart through rationally setting up to the switch circuit disconn
