Problems solved by technology

However, it also has certain disadvantages: 1. The light source of the LED lamp tube is composed of many LED lamp beads. No matter whether it is connected in parallel or in series, the LED lamp beads cannot be replaced if they are broken. The lamp cap at the end and the light-transmitting tube are fixed as a whole and cannot be disassembled; 2. Since the drive control circuit of the LED light source is encapsulated in the lamp cap, the heat dissipation environment is poor. Electronic components will inevitably have some problems and must be repaired. However, since the lamp holder and the projection tube are fixed as one, as long as there is a problem with the light source of the LED lamp or any small part of the electronic components, the user must repair the entire lamp. replace
Due to the current high cost and price of LEDs, ordinary consumers would rather choose traditional fluorescent lamps that often need to be replaced at this stage than LED lamps that are so expensive and cannot be repaired. Therefore, the demand for green light sources Promotion poses a big obstacle

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...

Abstract

The invention discloses a demountable LED lamp tube comprising a light-permeable tube, an LED substrate, a plurality of LEDs and a circuit board which carries an electronic drive unit. The LEDs are disposed on the LED substrate which is disposed within the light-permeable tube. Lamp holders are connected to two ends of the light-permeable tube. Each lamp holder is provided with pins. The circuit board which carries the electronic drive unit is disposed within the lamp holders and electrically connected with the LEDs. The pins are connected with the circuit board. The demountable LED lamp tube is characterized in that at least one end of the light-permeable tube is provided with a positioning end cover which is movably connected with the lamp holders in a threaded or inserted fit manner; each positioning end cover is internally provided with a cavity, and an end plate is disposed at the end, in connection with the light-permeable tube, of each cavity; each end plate is provided with a through hole which admits passage of an LED wire; the front of the circuit board which carries the electronic drive unit is inserted into the cavity of one positioning end cover. The demountable LED lamp tube is simple in structure, convenient to demount and maintain and high in luminous efficiency.

Description

technical field [0001] The invention relates to the technical field of lighting, and more specifically relates to an LED lamp tube. Background technique [0002] Traditional fluorescent tubes are also called fluorescent lamps. There is a filament at each end of the lamp. The tube is filled with a small amount of argon and thin mercury vapor. The inner wall of the tube is coated with fluorescent powder. The gas between the two filaments emits ultraviolet rays when conducting electricity. Make phosphors emit visible light. Due to the heavy metal pollutant "mercury", the scrapped fluorescent tubes pollute the environment very seriously. Therefore, the application of LED lamp tubes using LEDs as illuminants was born, and it has become the most ideal product to replace fluorescent tubes at the present stage. LED lamps are the same as traditional fluorescent lamps in terms of size and diameter. There are T5 tubes, T8 tubes, and T10 tubes, and the lengths are 0.6m, 0.9m, 1.2m, 1....
