[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0028] Example:

[0029] like Figure 1 - Figure 4 As shown, the utility model provides a technical solution for LED letter luminous characters:

[0030] As shown in the figure, an LED alphabetical luminous character comprises an alphabetical luminous font, which comprises an upper shell 1, a lower shell 2 adapted to the upper shell 1, a friction strip 3 provided on the surfaces of the upper shell 1 and the lower shell 2, and a light strip 4 located within the alphabetical luminous font. The upper shell 1 and the lower shell 2 are rectangular frame structures with a concave cavity in the middle, and the edges thereof are convex. Corresponding connecting pieces No. 1 and No. 2 are respectively provided on the convex portions of the frame.

[0031] The upper shell 1 is provided with a No. 1 connecting member, which includes a buckling groove 11 provided on the surface of the raised portion of the frame of the upper shell 1 and arranged in an inwardly concave manner, a limit frame 12 symmetrically provided on the lower part of the inner wall of the buckling groove 11, and reserved arc grooves 13 provided on both sides of the upper part of the buckling groove 11 and forming an integrated structure;

[0032] The lower shell 2 is provided with a No. 2 connecting part, which includes a fastening strip 21 provided on the raised part of the frame of the lower shell 2, a limit strip 22 provided on the left and right sides of the fastening strip 21 and fastened with the limit frame 12 during operation, an airbag bag 23 provided on the upper part of the left and right sides of the fastening strip 21, and a magnetic layer 24 provided on the outer surface of the airbag bag 23.

[0033] The friction strip 3 has a hollow structure inside and is provided with a mosquito repellent essential oil strip, which makes it easy for the LED letter luminous characters to be handled by hand when they need to be disassembled, and can also repel mosquitoes around them.

[0034] The friction strip 3 is divided into two parts of the shell and is a detachable structure, which is convenient for replacing the mosquito repellent essential oil strip.

[0035] The friction strips 3 are distributed at the corners of the outer surfaces of the upper shell 1 and the lower shell 2 and are arranged correspondingly.

[0036] A magnetic plate is provided inside the reserved arc groove 13 and cooperates with the magnetic layer 24 .

[0037] The air bag 23 is provided with a bulging structure in which gas is dripping. Part of the air bag 23 is engaged with the reserved arc groove 13 during operation.

[0038] The limiting strip 22 is a retractable structure, and the upper and lower parts away from the side of the buckling strip 21 are provided with inclined cross-sections, so that when the buckling strip is buckled with the buckling groove, it can quickly slide into the limiting frame 12 with it, thereby buckling the buckling strip and the buckling groove.

[0039] After the magnetic layer 24 cooperates with the airbag bag 23 to enter the reserved arc groove 13, it is in adsorption contact with the magnetic plate by utilizing the structure of opposite magnetic attraction.

[0040] The specific implementation principle is as follows: when it is necessary to install LED letter luminous characters, it is composed of two parts, namely, an upper shell 1 and a lower shell 2. After the required light strips 4 are installed inside them respectively, the upper shell 1 and the lower shell 2 are buckled together, and the buckling strip 21 extends into the buckling groove 11. During the process, the airbag bag 23 is squeezed and deformed under the cavity space restriction of the buckling groove 11. When the buckling strip 21 is fully extended into the buckling groove 11, the airbag bag 23 is partially placed in the reserved arc groove 13 after extrusion, and cooperates with the magnetic layer 24 set on the surface of the airbag bag 23 to further reinforce the contact with the magnetic plate set inside the reserved arc groove 13. Since the surface of the limit strip 22 is provided with an inclined cross-section structure, it follows the buckling strip 21 to extend into the buckling groove 11 and buckles with the limit frame 12, thereby improving the stable connection between the upper shell 1 and the lower shell 2 after installation.

[0041] Friction strips 3 are provided on the surfaces of the upper shell 1 and the lower shell 2, and the interior of the friction strips 3 is a hollow structure and is provided with mosquito repellent essential oil strips, which makes it convenient for the LED letter luminous characters to be handled by hand when they need to be disassembled, and can also repel mosquitoes around them.
