Description

Technical Field

[0001] The utility model relates to the field of luminous characters, in particular to an LED resin luminous character. Background Art

[0002] Resin luminous characters are a new type of LED luminous signs. They are popular in the advertising industry for their uniform and bright luminous effects and diverse design options. Their structure mainly consists of three parts: a character shell, filling resin, and a light source. The light source is set inside the character shell, and the top of the character shell is sealed by solidifying the filling resin. It has the advantages of uniform luminescence and high brightness.

[0003] The resin filling layer on the luminous characters is prone to cracking due to material aging and temperature changes, resulting in cracks and peeling of the resin filling layer (see CN201820063315.4, a background technology of resin luminous characters with anti-falling function). In addition, due to temperature influences (such as sunlight), the thermal expansion degrees of the character shell and the resin filling layer are inconsistent, and gaps are easily generated between the resin filling layer and the character shell (see application number CN201720626279.3, a background technology of luminous characters). The purpose of the present utility model is to propose a new luminous character structure to solve the above technical problems. Utility Model Content

[0004] The purpose of the utility model is to provide an LED resin luminous character to solve the problems mentioned in the background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: including a character shell, a mounting plate, a waterproof ring, an anti-cracking ring and a resin filling layer, the mounting plate is arranged in the character shell, the mounting plate matches the shape of the character shell and a support member for supporting the mounting plate is provided in the character shell, an LED light strip is installed on the mounting plate, the waterproof ring is located above the mounting plate and distributed along the circumference of the mounting plate, the waterproof ring includes a water-soluble outer shell composed of a water-soluble material and a water-curing resin filled in the water-soluble outer shell, the anti-cracking ring is located above the waterproof ring and distributed along the circumference of the mounting plate, the anti-cracking ring includes a brittle outer shell composed of a brittle material and an air-curing resin filled in the brittle outer shell, and the resin filling layer is filled in the space formed by the character shell and the mounting plate.

[0006] In order to optimize the above technical solution, further measures are taken as follows: it also includes horizontal bars, which are formed on the anti-cracking ring and are an integrated structure with the anti-cracking ring. The horizontal bars can play a supporting role to prevent the resin filling layer from collapsing or falling from the middle.

[0007] As a further improvement to the above technical solution: the horizontal strips are distributed on the anti-cracking ring in a crisscross pattern, and the staggered distribution has a good supporting effect on the vertical filling layer.

[0008] As a further improvement of the technical solution: it also includes a felt ring, which is located below the waterproof ring and distributed along the circumference of the mounting plate. The felt ring refers to an annular component composed of felt, and its purpose is to absorb water-curing resin and air-curing resin, block the flow of water-curing resin and air-curing resin, and concentrate the water-curing resin and air-curing resin on the circumference of the mounting plate to avoid the formation of a gap between the circumference of the mounting plate and the character shell.

[0009] As an improvement to the above technical solution: the surfaces of the water-soluble shell and the brittle shell are sprayed with a reflective coating, which can reflect light and avoid reducing shadows or dark spots in the vertical filling layer.

[0010] From the above description of the structure of the utility model, it can be seen that compared with the prior art, the utility model has the following advantages:

[0011] The utility model provides an LED resin luminous character. By arranging a waterproof ring and an anti-cracking ring inside the character shell, the resin filling layer on the luminous character can be prevented from cracking and peeling off. At the same time, the waterproof performance of the luminous character can be improved, and water vapor can be prevented from entering the interior of the luminous character and affecting the normal operation of the luminous character.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] Example

[0019] See also Figure 1-3 The utility model provides an LED resin luminous character, comprising a character shell 1, a mounting plate 2, a waterproof ring 3, an anti-cracking ring 4, a resin filling layer 5 and a felt ring 6.

[0020] The mounting plate 2 is arranged in the letter case 1 . The mounting plate 2 matches the letter case 1 in shape. A support member 101 for supporting the mounting plate 2 is provided in the letter case 1 . An LED light strip 201 is installed on the mounting plate 2 .

[0021] The waterproof ring 3 is located above the mounting plate 2 and distributed circumferentially along the mounting plate 2. The waterproof ring 3 includes a water-soluble shell 301 made of a water-soluble material and a water-curable resin 302 filled in the water-soluble shell 301. The water-soluble shell 301 refers to a shell-shaped component made of a water-soluble material, and the water-curable resin 302 refers to a resin material that can be cured after contact with water in the prior art.

[0022] The anti-crack ring 4 is located above the waterproof ring 3 and distributed circumferentially along the mounting plate 2. The anti-crack ring 4 includes a brittle shell 401 made of a brittle material and an air-curing resin 402 filled in the brittle shell 401. The air-curing resin 402 refers to a resin material in the prior art that can react and cure after contact with air.

[0023] The anti-crack ring 4 also includes horizontal stripes 403, which are formed on the anti-crack ring 4 and are an integrated structure with the anti-crack ring 4. The horizontal stripes 403 are distributed on the anti-crack ring 4 in a criss-cross pattern. The surfaces of the water-soluble shell 301 and the brittle shell 401 are sprayed with a reflective coating.

[0024] The resin filling layer 5 is filled in the space formed by the case 1 and the mounting plate 2 .

[0025] The felt ring 6 is located below the waterproof ring 3 and distributed circumferentially along the mounting plate 2 . The felt ring 6 refers to a ring-shaped component made of felt.

[0026] Working principle: The anti-cracking ring 4 and the horizontal strips 403 on the anti-cracking ring 4 can serve as the skeleton of the resin filling layer 5 to support the resin filling layer 5, thereby preventing the resin filling layer 5 from peeling off after cracking. In addition, when the resin filling layer 5 cracks, the brittle shell 401 of the anti-cracking ring 4 can crack to allow the air-curing resin 402 to seep out. The air-curing resin 402 can be rapidly cured after contacting with the air, thereby delaying the cracking of the resin filling layer 5 and simultaneously playing a bonding role to prevent the resin filling layer 5 from peeling off.

[0027] When a gap is created between the resin filling layer 5 and the letter case 1 and water vapor penetrates into the letter case 1, the water-soluble shell 301 of the waterproof ring 3 can dissolve and allow the water-curable resin 302 to seep out. The water-curable resin 302 can quickly solidify after contact with water, thereby playing a bonding role to improve the bonding between the letter case 1 and the resin filling layer 5, and at the same time playing a blocking role to fill the gap between the letter case 1 and the vertical filling layer, thereby preventing water vapor from entering the letter case 1.

[0028] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
