LED tube for improved handling efficiency

The present invention relates to an LED tube, and more particularly to an LED tube capable of improving assembly or disassembly efficiency.

In recent years, the development of light-emitting diodes (LEDs) has been rapid. Compared with traditional lamps, the advantages of LEDs are small size, energy saving, and environmental protection. Therefore, LEDs on the market have gradually replaced traditional lamps and become the mainstream of lighting equipment-related industries. .

A known LED lamp tube system is disclosed in FIG. 7 , which comprises a lamp tube 81 having a lamp plate 82 disposed therein. The opposite ends of the lamp tube 81 (only one end of which is shown) are respectively provided with a cap. a cover 83; the light board 82 is provided with a plurality of light-emitting diodes 821 and a connecting socket 822. The cap 83 is provided with two pins 832 from the outer side to the inner side, and a connecting plug 833 and two inner sides of the cap 83 are provided. The power cord 84 is electrically connected to the pin 832 and one end of the electric wire 84. The other end of the power cord 84 is electrically connected to the connecting socket 822, and the connecting plug 833 is connected to the power socket 84 and the connecting socket 822. The manner of electrical connection is to supply the light-emitting diode 821 on the lamp board 82 to the purpose of emitting light in the lamp tube 81.

And the assembly process is complicated; and another LED tube uses two opposite sliding grooves 911 on the inner wall of the lamp tube 91 to fix the lamp plate 92, and the lamp plate 92 is clamped through the fixing clip 931 in the cap 93. In this way, although the combination stability of the cap 93 and the lamp plate 92 can be increased, the structure is relatively complicated, which is not economical; when one of the lamp plate 92 or the cap 93 is unbearable, it needs to be replaced. When a new situation occurs, the entire set of LED tubes needs to be replaced together, and the cost of the lamp 81 and the caps 83, 93 is increased, and the cost of the operator is increased, and if the entire group of LED tubes is replaced, It is also quite inconvenient.

Or use the purpose of cost.

The main technical means for achieving the above purpose is that the LED lamp tube capable of improving the loading and unloading efficiency includes: a lamp cover which is hollow tubular and has openings formed at opposite ends; an LED module is mainly used in one Two power supply contacts are disposed at two ends of the substrate, and a plurality of light-emitting diodes are disposed on the substrate, and are axially disposed in the lampshade; the two lamp caps are respectively disposed at two ends of the lamp cover, and are respectively disposed There are two pins for electrically connecting the external power source; a fixing slot is formed between the inner walls of the lamp cap; the two power modules are respectively disposed in the fixing slots of the two lamp caps, and the power module is provided with two conductive elastic pieces for the foregoing The LED module is pluggable and fixed, and the power contact of the LED module is in electrical contact with the conductive elastic piece.

The LED lamp tube capable of improving the loading and unloading efficiency is fixed to the lamp cap through the lamp caps respectively disposed at the two ends of the lamp cover, and the substrate is suspended in the lamp cover, because the conductive mode is mainly The electrical contact between the power contact on the substrate and the conductive elastic piece in the lamp cap eliminates the usual complicated welding steps, thereby improving the efficiency of assembling or disassembling the LED lamp and saving the manufacturing cost thereof. Efficacy, in addition, when one of the LED modules or lamp holders is unusable and needs to be replaced, the user does not need to replace the entire set of LED tubes, thus saving the need for consumable components. Change the cost.
