Abstract
Description
Technical Field
[0001] This application relates to the field of illuminated sign technology, and in particular to a novel detachable acrylic illuminated sign structure. Background Technology
[0002] Illuminated letters are illuminated signs made of a shell, panel, and base plate, using light-emitting diodes (LEDs) as the light source. Illuminated letters are characterized by rich colors and personalization[1], making the signs more humanized and playing an important role in the publicity of enterprises, shops, and exhibitions. Common types include 3D printed illuminated letters, mini letters, aluminum edge letters, resin letters, stainless steel letters, vacuum-formed letters, electroplated letters, perforated LED beads with exposed beads, acrylic letters, iron sheet painted letters, crystal letters, etc.
[0003] Existing glass neon illuminated signs have the following disadvantages when in use:
[0004] 1. Fragility
[0005] Glass is fragile and easily breaks due to impacts, vibrations, or improper installation. The risk is even higher outdoors or in high-traffic areas, and the fragments may also pose safety hazards.
[0006] 2. High energy consumption
[0007] Traditional neon lights rely on high-voltage transformers for operation, resulting in high power consumption over long periods. Compared to modern technologies such as LEDs, they are less energy efficient, increasing operating costs.
[0008] 3. High maintenance costs
[0009] Repairing damage is complex and requires professional technicians (such as sealing the glass tube and filling with inert gas), resulting in high repair costs and time.
[0010] 4. Limited lifespan
[0011] Electrodes and phosphors will gradually age, causing brightness to decrease, with an average lifespan of about 10,000 to 20,000 hours, which is lower than that of LEDs (which can reach more than 50,000 hours).
[0012] 5. Poor environmental adaptability
[0013] Extreme temperatures (such as extreme cold or heat) may cause glass to crack or gas pressure changes, affecting performance; humid environments may cause electrical component malfunctions.
[0014] 6. Complex installation
[0015] Custom-made curved glass tubes are required, and the installation of fixed brackets and high-voltage lines is complicated, especially for large signs, which have a long installation cycle and are difficult to install.
[0016] 7. Environmental issues
[0017] It contains a small amount of mercury (mercury vapor is required for phosphor excitation), and must be professionally recycled and disposed of after disposal, otherwise it may pollute the environment.
[0018] 8. Safety hazards
[0019] High-voltage power supplies (approximately 110-220 volts) pose a risk of electric shock, and aging insulation may cause a fire.
[0020] Therefore, there is an urgent need in this field for a new type of detachable neon illuminated sign to achieve a simpler, more aesthetically pleasing, safer, more practical, and pollution-free design. Utility Model Content
[0021] To make the use of neon illuminated signs simpler, more aesthetically pleasing, safer, more practical, and pollution-free.

[0036] 5. The detachable acrylic illuminated sign structure of this utility model is pollution-free: it contains no harmful materials such as glass and mercury, and is recyclable, which is in line with the trend of environmental protection.
[0037] 6. The detachable acrylic illuminated sign structure of this utility model operates at low temperatures and generates little heat from the LEDs, avoiding the risk of burns or fires; the low-voltage power supply typically uses a safe voltage of 12V / 24V, making it especially suitable for public places.

[0045] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0046] This application discloses a novel detachable acrylic illuminated letter structure.
[0047] Reference Figures 1-3 A novel detachable acrylic illuminated letter structure includes a support structure 1, a bending and luminous structure 2, and a power supply connection structure 3.
[0048] The supporting structure 1 has a base plate 11, and the bending light-emitting structure 2 and the power supply docking structure 3 are all installed on the base plate 11. The bending light-emitting structure 2 includes a light strip 21, a bending light tube 22, and a heat shrink tubing 23. The bending light tube 22 is an acrylic tube and can be detachably installed on one side of the base plate 11. The acrylic material has good flexibility and can be bent into complex shapes, such as letters, patterns, and curves, to meet personalized customization needs. The light strip 21 is installed inside the bending light tube 22 and is covered with a heat shrink tubing 23. The light strip 21 uses LED lights and can emit light for more than 50,000 hours, which is more efficient and longer-lasting than traditional light sources. The power supply docking structure 3 is installed on the side of the base plate 11 away from the bending light tube 22 and can supply power to the light strip 21 inside the bending light tube 22 from both ends of the bending light tube 22. The dual-head power supply allows it to still emit light normally even if one end is damaged, without the need for repair, thus reducing the overall maintenance rate.
[0049] Reference Figure 1 and Figure 2 In a further embodiment, the power supply docking structure 3 includes a power supply circuit board 31, an acrylic insulating tube 32, a metal plug 33, and a transformer 34. The power supply circuit board 31 is fixedly mounted on the base plate 11 with screws. Both ends of the bent lamp tube 22 are electrically connected to the power supply circuit board 31 through corresponding metal plugs 33. The acrylic insulating tube 32 is inserted into the base plate 11 and sleeved on the outside of the metal plug 33. The transformer 34 is mounted on the base plate 11 and electrically connected to the power supply circuit board 31 through connecting wires 4. In this embodiment, the electrical connection between the power supply circuit board 31, the metal plug 33, and the transformer is prior art and will not be described in detail.
[0050] Furthermore, the transformer 34 is electrically connected to the power supply circuit board 31 through the rectifier bridge 5. By adding the rectifier bridge 5 inside, the positive and negative poles of the output terminals can be eliminated, simplifying the on-site installation. In this embodiment, the use and installation of the rectifier bridge 5 are existing technologies and will not be described in detail.
[0051] Reference Figure 2 Furthermore, the metal plug 33 includes a male metal plug 331 and a female metal plug 332. The male metal plug 331 is installed inside the acrylic insulating tube 32 and welded with connecting wires 4 for connecting the power supply circuit board 31. The back of the male metal plug 331 is coated with fixing adhesive and fitted with adhesive heat shrink tubing 6, thereby making the connection between the male metal plug 331 and the acrylic insulating tube 32 tighter. The female metal plug 332 is electrically connected to the end of the bent lamp tube 22 through enameled wire 7, supplying power to the LED light strip 21 and connecting the power supply docking structure 3. This improvement allows the illuminated letter to be disassembled and replaced individually, greatly reducing the customer's maintenance costs and the convenience of on-site construction.
[0052] Reference Figure 1 and Figure 3The support structure 1 also includes a bracket 12 and fixing screws (not shown in the figure). The bent lamp tube 22 is fastened to the base plate 11 by the bracket 12. The bracket 12 is fixedly connected to the base plate 11 by the fixing screws, thereby ensuring the installation stability of the bent light-emitting structure 2.
[0053] Furthermore, the base plate 11 is provided with a mold groove 111 for embedding the bent lamp tube 22. The mold groove 111 matches the shape of the bent lamp tube 22, thereby further ensuring the installation stability of the bent light-emitting structure 2.
[0054] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered by the protection of this application.
[0055] Within the scope.
