Embodiment 1
[0035] Such as Figure 1-Figure 9 As shown, a detachable LED lamp tube of the present invention includes a light-transmitting tube 1, an LED substrate 2, a plurality of LED lamp beads 3 and a circuit board 4 carrying electronic drive components. The light-transmitting tube 1 is made of plastic tube or glass tube. A plurality of LED lamp beads 3 are arranged on the LED substrate 2, and the LED substrate 2 is arranged in the light-transmitting tube 1, and the two ends of the light-transmitting tube are connected with lamp caps 5, and the lamp caps 5 are provided with lamp pins 5-1, carrying electronic drive components The circuit board is set inside the lamp holder 5 and is electrically connected to a plurality of LED lamp beads. The lamp pin 5-1 is connected to the circuit board 4 through a wire. The flexible connection is in the form of screw thread or plug-in fit, and what this embodiment adopts is the mode of plug-in fit. The positioning end cover 6 has a built-in cavity 6...
Embodiment 2
[0040] Such as Figure 11 , in this embodiment, the lamp caps at the left and right ends of the light-transmitting tube are provided with two lamp pins 5-1, and the two lamp pins of the lamp cap at one end are independent of each other, serving as N pole and L pole respectively, and the other end The two lamp feet of the lamp head are only used as the support feet of the lamp tube and are not powered.
Embodiment 3
[0042] Such as Figure 12 , in this embodiment, the lamp caps at the left and right ends of the light projection tube are provided with two lamp pins 5-1, and the two lamp pins of the lamp cap at one end are independent of each other, and one of the lamp pins is used as the N pole. The other one is only used as the support leg of the lamp tube; the two lamp legs of the lamp cap at the other end are connected to each other, one of the lamp legs is used as the L pole, and the other is only used as the support leg of the lamp tube, matching the inductance of the existing ordinary fluorescent lamp bracket use.
[0043] Compared with ordinary LED fluorescent tubes on the market, the present invention has the biggest features: 1. It has maintainability, that is to say, the plastic parts at both ends of the LEDs of ordinary LED fluorescent tubes on the market are not detachable, and they are directly glued to the LED. On the glass outer tube, if the circuit board is damaged or other...
