AI Technical Summary
Traditional illuminated letters on wood veneer surfaces damage the wood veneer surface by embedding acrylic letters through a hollowed-out design. This results in uneven edge gaps that are prone to light leakage, making the process difficult and costly, and making it especially difficult to achieve an illuminated effect for small letters.
The structure consists of a light guide plate, a light-shielding paint layer, a paint layer, and a wood veneer layer. The outline of the illuminated letter is carved out on the light-shielding paint layer using a carving machine. Combined with the light-transmitting part and the light-transmitting wood veneer layer, the luminous effect is achieved. At the same time, LED light source is used to improve light efficiency and reduce power consumption.
It achieves a seamless, uniform luminous effect on the wood veneer surface, is easy to process and low in cost, is suitable for small letter illumination, and is aesthetically pleasing and flexible, meeting customer needs.

TECHNICAL FIELD
[0001] The utility model belongs to the technical field of advertisement decoration, especially relates to a wood grain LED light-emitting character display board. BACKGROUND
[0002] Light-emitting characters have wide applications in the field of advertisement media, and are light-emitting signs made of light-emitting diodes (LED) as light sources, a character shell, a panel and a bottom plate. Light-emitting characters have the characteristics of rich colors and personalization, making the signs more humanized, and play an important role in the publicity of enterprises, shops and exhibition displays. Common light-emitting characters include 3D printed light-emitting characters, mini characters, aluminum edge characters, resin characters, stainless steel characters, suction plastic characters, electroplated characters, characters with exposed punched lamp beads, acrylic characters, iron sheet baked enamel characters and crystal characters.
[0003] In indoor scenes, such as exhibition displays and background wall logos, a decorative layer needs to be laid on the surface of the display board, and wood grain decoration is commonly used. However, in traditional wood surface light-emitting characters, the wood surface of the light-emitting part is hollowed out, and then a milky white acrylic character is embedded. This destroys the wood surface, and the hollowed-out part does not perfectly match the acrylic character, the edge gap is uneven, and light leakage is easy to occur. It is not only not beautiful, but also difficult to process and high in cost. Especially when it comes to very small characters, it is difficult to achieve the light-emitting requirement.
[0004] Therefore, the above problems need to be solved. UTILITY MODEL CONTENT
[0005] UTILITY MODEL OBJECTIVE: In order to overcome the above shortcomings, the utility model aims to provide a wood grain LED light-emitting character display board, which has a simple structure and a reasonable design, changes the traditional structure of wood surface hollowing and embedding an acrylic character, keeps the wood surface intact, realizes the light-emitting character effect, and is also suitable for small characters.
[0006] TECHNICAL SCHEME: In order to achieve the above objective, the utility model provides a wood grain LED light-emitting character display board, which comprises a light guide plate, a light-shielding paint layer, a paint layer and a wood layer.
[0007] The light-shielding paint layer and the paint layer are coated on the light guide plate in sequence, and the wood layer is arranged on the paint layer.
[0008] Further, the light-shielding paint layer is arranged on the exit surface of the light guide plate. The light guide plate scatters uniform light on the light-shielding paint layer.
[0009] Further, the light-shielding paint layer and the black paint layer are provided with a light-transmitting part consistent with the outline of the light-emitting character. The part coated with the light-shielding paint does not transmit light, while the light-transmitting part does not block light, and finally forms a light-emitting character on the surface of the display board.
[0010] Furthermore, the veneer layer is a translucent veneer layer. Light can be seen through the veneer layer.
[0011] Furthermore, the paint layer is a black paint layer.
[0012] Furthermore, it also includes an outer casing, which is a box-shaped structure with an opening at the top, and the light guide plate is disposed inside the casing. The display panel is mounted on a wall or other location using this casing.
[0013] Furthermore, the housing also includes an LED light source, which is positioned on the incident surface of the light guide plate. The light emitted by the LED light source is transformed into uniform light through the light guide plate, while also improving the light utilization efficiency; under the same area of light emission brightness, it has high luminous efficiency and low power consumption.
[0014] Furthermore, a power interface is provided on the side of the housing, through which the LED light source is connected to an external power source.
[0015] As can be seen from the above technical solution, this utility model has the following beneficial effects compared with the prior art:
[0016] 1. The wood grain LED illuminated letter display board provided by this utility model has a simple structure. The light-shielding paint is cut out from the area that needs to be illuminated by a carving machine, which changes the traditional structure of hollowing out the wood veneer surface to install acrylic letters. The wood veneer layer on the surface is intact and unchanged. When electricity is applied, illuminated letters are formed on the surface. When the power is off, the surface is intact again, making the whole more beautiful.
[0017] 2. This display board is easy to process and has low cost. Its structure is also suitable for very small illuminated letters, solving the problem that small letters are difficult to illuminate in the past. It is highly flexible and can meet most of the needs of customers. Attached Figure Description
[0018] Figure 1 This is a structural schematic diagram of a wood grain LED illuminated letter display board according to the present invention.
[0019] In the diagram: 1-outer shell, 2-light guide plate, 3-light-shielding paint layer, 31-light-shielding part, 4-paint layer, 5-wood veneer layer. Detailed Implementation
[0020] It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention.
[0021] like Figure 1 As shown: A wood grain LED illuminated letter display board includes a light guide plate 2, a light-shielding paint layer 3, a paint layer 4, and a wood veneer layer 5;

[0023] The light shielding paint layer 3 is arranged on the exit surface of the light guide plate 2.
[0024] In a further optimization, the light shielding paint layer 3 and the black paint layer 4 are provided with light transmitting parts 31 consistent with the outline of the light emitting word wheel. It should be noted that the light shielding paint layer can be replaced by other light shielding materials, and the selection can be made according to the specific use scenario.
[0025] In the embodiment, the veneer layer 5 is a light transmitting veneer layer. The veneer layer 5 is a decorative layer, and can be of other patterns and materials, but needs to have certain light transmitting property.
[0026] The paint layer 4 is a black paint layer.
[0027] In addition, the utility model also includes a shell 1, the shell 1 is the box body of upper opening, the light guide plate 2 is arranged in the shell 1. As a preferred scheme, quick plug structures can be arranged inside and outside the shell, facilitating the installation of the light guide plate 2 and the installation of the shell 1 itself.
[0028] The shell 1 is also provided with an LED light source, and the LED light source is arranged on the incident surface of the light guide plate 2.
[0029] In a preferred embodiment, the shell 1 is provided with a power supply interface 11 on the side surface, and the LED light source is connected to an external power supply through the power supply interface 11.
