Description

Technical Field

[0001] This utility model relates to the field of luminous doorplate technology, specifically a fully luminous doorplate with replaceable light source. Background Technology

[0002] Currently, all nameplates (nameplates for government agencies, other organizations, or other businesses) in China are made of materials such as solid wood and stainless steel. Government agency nameplates, in particular, commonly feature a white background with black lettering, while Party committees use a white background with red lettering for distinction. The text is in Song typeface (standard Song or artistic Song). Because these materials are not translucent, especially at night without proper lighting, the original appearance and shape of the nameplates (or other business signs) cannot be fully displayed, making it impossible to read the information and characters.

[0003] The utility model patent, patent number ZL200320124205.8, is entitled "A Display Device for an Illuminated Doorplate." It discloses a box-shaped device comprising a light source within the box and a character plate on the display side of the box. The inner surfaces of the five panels on the box (excluding the display side) are all translucent. Furthermore, the characters on the character plate are translucent, while the other parts are opaque. This allows the light source to be diffused and refracted through the five surfaces within the box, resulting in uniform light that is projected onto the display side of the box. Therefore, a single light source is sufficient to achieve uniform light distribution. The translucent nature of the characters on the display side of the character plate further enhances the clarity of the displayed content (characters), making them visible from a considerable distance.

[0004] However, the characters on the sign are translucent, while the rest are opaque. The shape of the sign itself is not properly represented; with only one light source, the characters are unevenly illuminated, making the sign unattractive and lacking in three-dimensionality. Summary of the Invention

[0005] In view of the shortcomings of the prior art and to solve the problems mentioned in the background art, the technical problem to be solved by this utility model is to provide a fully luminous doorplate with replaceable light source that is easy to maintain by replacing different light sources, can adjust the position and brightness of the light source according to needs, and can efficiently guide light under strong light at night or during the day, thus demonstrating a unique identification function.

[0006] The technical problem to be solved by this utility model is achieved through the following technical solution: a fully illuminated doorplate with replaceable light source, comprising a doorplate body made of transparent material, the doorplate body including a back surface and five light-transmitting surfaces, the five light-transmitting surfaces including a light-transmitting top surface and four light-transmitting side surfaces, the surfaces of the five light-transmitting surfaces are sandblasted to form a frosted layer, the four sides of the doorplate body are provided with a full circle of positioning light grooves along the center line, and a detachable light source is embedded in the positioning light grooves, the light source on one side illuminates the light-transmitting surface on the opposite side to form diffracted light and scattered light, the light source on the four sides and the diffracted light and scattered light generated by the light-transmitting surfaces illuminate the light-transmitting top surface;

[0007] By using five translucent surfaces, the diffraction and scattering effects of light are maximized, forming a five-sided luminous body. When the light source shines on the translucent surfaces, the resulting diffracted and scattered light is effectively distributed across all areas of the signboard, ensuring uniform illumination from different angles. The light source within the positioning light trough can be freely disassembled and replaced, facilitating maintenance by changing different light sources. The position and brightness of the light source can be adjusted as needed, and the light source technology can be updated to ensure the continued effective use of the signboard and optimize its lighting efficiency.

[0008] The combination of a translucent surface and a light source improves the efficiency of light energy utilization. Scattered and diffracted light achieve a more uniform illumination effect at lower power, reducing energy consumption and achieving energy-saving effects.

[0009] Using replaceable light sources avoids replacing the entire doorplate structure, while utilizing efficient lighting technology improves the overall energy efficiency and environmental performance of the system. The doorplate's translucent function ensures clear readability even under strong or complex lighting conditions.

[0010] The translucent top surface features deeply engraved negative lettering, within which colored resin is poured to form the characters. When illuminated by a beam of light, these characters create different colored shadows or darker visual effects. The doorplate not only serves an identification function but also possesses artistic decorative qualities, boasting a strong visual impact and exhibiting different effects depending on the light source. The use of colored resin allows the characters to express different colors in different usage scenarios, enhancing the doorplate's artistry and recognizability, and increasing its uniqueness and appeal.

[0011] As a further embodiment of this invention, the light source includes a light source holder, which is a strip-shaped groove. A light strip is provided along the length of the bottom of the groove, and the opening of the groove faces the doorplate. Light from the light source is emitted along the opening of the groove and illuminates the interior of the doorplate. The light emitted by the light source is efficiently diffracted and scattered by the light-transmitting surface, enhancing the overall visual appeal and three-dimensional effect of the doorplate.

[0012] As a further embodiment of this invention, the light source holder is a strip-shaped groove made of aluminum alloy. The two sides of the strip-shaped groove are clamped to the positioning light groove, and the opening of the strip-shaped groove aligns with the bottom of the positioning light groove. The strip-shaped groove protrudes from the positioning light groove. This clamping structure effectively prevents the light source holder from loosening or shifting during use, improving the overall structural stability. The protruding strip-shaped groove facilitates installation and disassembly when replacing the light source.

[0013] As a further improvement of this invention, the positioning light groove is machined to a depth of 10mm-12mm, and the bottom surface of the groove is polished to form a fully translucent polished surface with a polishing degree of 0.1μm to 0.2μm. The polished surface reduces surface irregularities, making the diffracted light more uniform and effective. This minimizes light scattering and energy loss, improving the brightness and illumination accuracy of the light source.

[0014] As a further embodiment of this utility model, the recessed depth of the negative mold is >1mm, and the entire surface of the negative mold is polished to form a polished surface with a polishing degree of 0.1μm to 0.2μm.

[0015] Fine polishing makes the surface of the negative mold more uniformly transparent. The smooth surface of the negative mold can provide a more uniform pressure distribution during the molding process, avoiding bubbles, cracks or other surface defects during molding, and ensuring the accuracy and beauty of the characters.

[0016] As a further embodiment of this invention, the doorplate is made of a transparent shaped sheet, which may be made of polymethyl methacrylate (PMMA), polystyrene (PS), acrylonitrile-butadiene-styrene copolymer (ABS), polycarbonate (PC), or polyvinyl chloride (PVC). Using transparent or semi-transparent materials ensures good light transmittance of the doorplate, enhancing its visual appeal. This allows the doorplate to be clearly visible even in daylight or low-light environments, resulting in high readability and aesthetics.

[0017] As a further embodiment of this invention, the surface of the back of the plate is a smooth, glossy surface. A light-guiding ink layer with a dotted array, controlling the speed and direction of light propagation, is screen-printed using a 300-600 mesh screen. A reflective film is then rolled onto the light-guiding ink layer. The light-guiding ink layer effectively enhances the diffraction effect, improves the efficiency of light diffraction, and enhances light efficiency. The function of the light-guiding ink layer after screen printing is to precisely control the speed and direction of light propagation. It effectively adjusts the scattering and diffraction paths of light, ensuring that light propagates in the desired direction and enhancing the uniformity of illumination.

[0018] Reflective film effectively reflects light, increasing the light reflectivity of the surface. This is especially important for locations requiring high visibility in low-light environments (such as road signs, billboards, and directional signs). Reflective film enhances the clarity of signs or doorplates, making them easier to see both day and night, and easier for people to identify targets at night or in adverse weather conditions.

[0019] As a further embodiment of this invention, the surface of the back of the plate is a smooth, glossy surface. A dot matrix layer is formed by laser dotting, with a density of >300 mesh. A reflective film is then rolled and attached to the outer surface of the dot matrix layer. The superposition effect of the dot matrix layer and the reflective film effectively improves the reflectivity of the plate. In low-light environments, the reflected light makes the entire plate glow, which is crucial for improving visibility in dark or dimly lit conditions.

[0020] Compared with existing technologies, the beneficial effects of this utility model are as follows: This doorplate includes a doorplate body made of transparent material. The doorplate body includes a back surface and five light-transmitting surfaces. The five light-transmitting surfaces include a light-transmitting top surface and four light-transmitting side surfaces. The surfaces of the five light-transmitting surfaces and the back surface of the doorplate are sandblasted to form a frosted layer. Through the five light-transmitting surfaces, the diffraction and scattering effects of light are maximized. When a light source shines on the light-transmitting surfaces, the diffracted and scattered light generated can be effectively distributed in various areas of the doorplate, ensuring that the doorplate emits light uniformly at different angles, forming a fully luminous doorplate. The doorplate has a ring of positioning light grooves along its center line on all four sides. Each positioning light groove contains a detachable light source. The light source on one side illuminates the light-transmitting surface on the opposite side, creating diffracted and scattered light. The diffracted and scattered light from the surrounding light sources and the light-transmitting surface illuminates the top surface. The light sources in the positioning light grooves can be freely removed and replaced, facilitating maintenance by changing different light sources. The position and brightness of the light sources can be adjusted as needed, and the light source technology can be updated to ensure the continuous and effective use of the doorplate and optimize the lighting effect.

[0021] The combination of a translucent surface and a light source improves the efficiency of light energy utilization. Scattered and diffracted light achieve a more uniform illumination effect at lower power, reducing energy consumption and achieving energy-saving effects.

[0022] Using replaceable light sources avoids replacing the entire doorplate structure, while utilizing efficient lighting technology improves the overall energy efficiency and environmental performance of the system. The doorplate's translucent function ensures clear readability even under strong or complex lighting conditions.

[0023] The translucent top surface features deeply engraved negative lettering, within which colored resin is poured to form the characters. When illuminated by a beam of light, these characters create different colored shadows or darker visual effects. The doorplate not only serves an identification function but also possesses artistic decorative qualities, exhibiting a strong visual impact and displaying different effects depending on the light source. The use of colored resin allows the characters to express different colors in different usage scenarios, enhancing the doorplate's artistry and recognizability, and increasing its uniqueness and appeal.

[0024] Using transparent or semi-transparent materials ensures good light transmittance for the doorplate, enhancing its visual appeal. This allows the doorplate to be clearly visible even during the day or in low-light environments, resulting in high readability and aesthetics.

[0025] The back surface of the board is smooth and glossy. A light-guiding ink layer with a dotted array, controlling the speed and direction of light propagation, is screen-printed using a 300-600 mesh screen. A reflective film is then rolled onto the light-guiding ink layer. The superposition effect of the dotted array layer and the reflective film effectively reflects light, increasing the light reflectivity of the board. This is especially important for locations requiring high visibility in low-light environments (such as road signs, billboards, and directional signs). The reflective film enhances the clarity of signs or doorplates, making them easier to see both day and night, and allowing people to more easily identify targets at night or in adverse weather conditions.

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0037] The serial numbers assigned to components in this document, such as "first," "second," etc., are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application...

[0038] Unless otherwise specified, "connection" includes both direct and indirect connections. In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0039] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature means that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature means that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0040] As shown in Figures 1-6, a fully illuminated doorplate with a replaceable light source includes a doorplate body 2 made of transparent material. The doorplate body is made of transparent molded sheet material, which can be polymethyl methacrylate (PMMA), polystyrene (PS), acrylonitrile-butadiene-styrene copolymer (ABS), polycarbonate (PC), or polyvinyl chloride (PVC). The appropriate material is selected based on the actual usage scenario.

[0041] As attached Figure 8 As shown, the signboard includes a back surface 203 and five light-transmitting surfaces. The back surface 203 is a smooth surface, and the screen is a 400mm mesh screen. A dot-matrix array layer 231 printed with light-guiding ink is used. The smooth surface of the transparent board is first polished and then cleaned to ensure a dust-free, good adhesion surface. The light-guiding ink is a type of ink containing specific light-guiding components, which can effectively transmit light under illumination through the light-guiding effect of the ink layer. This type of light-guiding ink typically contains optical particles, such as fluorescent materials or light-guiding fibers. It usually has high transparency or translucency, allowing light to pass through. Through special design, the direction and intensity of light propagation can also be controlled. By adding light-guiding microparticles or other optical materials, the light-guiding ink can guide and disperse light, causing it to propagate along a certain path on the surface or within the material. Choosing a suitable light-guiding ink for screen printing is crucial, ensuring it has appropriate viscosity and flowability. Light-guiding ink that is too viscous or too thin will affect the screen printing effect.

[0042] A reflective film 232 is rolled onto the light-guiding ink layer. The reflective film efficiently reflects light and transmits it to the other five light-transmitting layers. In low-light environments (such as road signs, billboards, directional signs, etc.), it enhances the clarity of signs or doorplates, making them easier to see both day and night, and making it easier for people to identify targets at night or in adverse weather conditions.

[0043] The five light-transmitting surfaces include a light-transmitting top surface and four light-transmitting side surfaces. The surfaces of the five light-transmitting surfaces are sandblasted to form a frosted layer. A full circle of positioning light grooves 201 is opened along the center line on all four sides of the doorplate. The depth of the positioning light grooves is processed to 11mm. The bottom surface of the positioning light grooves 201 is polished to form a fully light-transmitting polished surface with a polishing degree of 0.15μm.

[0044] As attached Figure 7As shown, a detachable light source 4 is embedded in the positioning light groove. The light source includes a light source holder 1, which is a strip groove 101 made of aluminum alloy. A light strip is provided along the length of the bottom of the strip groove. Each side of the strip groove is provided with a wire hole. The wire is electrically connected to the light strip through the wire hole. The wire is connected to an external power source. The opening of the strip groove faces the door plate. The light from the light source shines into the plate through the opening of the strip groove.

[0045] The two sides of the strip groove 101 are engaged with the positioning light groove 201, and the opening of the strip groove 101 is aligned with the bottom of the positioning light groove. The strip groove 101 protrudes from the positioning light groove 201. The strip grooves are sequentially inserted into the positioning light groove 201 in a clockwise or counterclockwise direction. A light source on one side illuminates the light-transmitting surface on the opposite side, creating diffracted and scattered light. The diffracted and scattered light from the surrounding light sources and the light-transmitting surface illuminates the top surface of the light-transmitting area, forming a fully illuminated doorplate that displays its light transmission function, ensuring clear readability even under strong or complex lighting conditions.

[0046] When it is necessary to replace the light strip or perform maintenance, manually pull out the positioning light slot through the part of the strip groove 101 that protrudes from the positioning light slot, replace the light strip, and then insert the strip groove into the positioning light slot in the same way.

[0047] The characters on doorplates serve multiple functions, including identification, location tracking, security, management, and communication, playing a vital role in daily life, urban management, and social operations. They help achieve accurate geographic location identification, among other things.

[0048] The translucent top surface is deeply engraved with a negative character mold 205, the recessed depth of which is 4mm. The entire surface of the negative character mold is polished to form a polished surface with a polishing degree of 0.1μm.

[0049] Colored resin is poured into the negative mold to form character symbols 3. When illuminated by a beam of light, these symbols exhibit different colored shadows or dark visual effects. Light emitted from the surrounding LED strips is scattered by the frosted layer 5, illuminating the colored resin and creating easily recognizable signage. Different colored resins are used in different locations to achieve different color expressions. Example

[0050] As attached Figure 9 As shown, the surface of the back side 203 of the plate is a smooth surface, and a dot matrix layer 233 is formed by laser dotting. The density of the dot matrix layer 233 is 600 mesh, and a reflective film is rolled and attached to the outer surface of the dot matrix layer.

[0051] When scattered light shines on the dot matrix layer and is reflected by the reflective film, the reflective film enhances the light reflection effect, making the sign appear to be illuminated from head to toe. The light diffracted from the back of the board shines on the interface between the bottom surface of the negative mold and the cast colored resin that forms the character symbol, so that the surface of the character symbol in contact with the negative mold is illuminated, forming a three-dimensional character symbol expression effect.

[0052] In this specification, the terms "connection," "installation," "fixing," and "setting" are interpreted broadly. For example, "connection" can mean a fixed connection or an indirect connection via intermediate components without affecting the relationship between components or the technical effect; it can also mean an integral connection or a partial connection. Those skilled in the art can understand the specific meaning of these terms in this utility model or utility model based on the specific circumstances. The above description is merely a preferred embodiment of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
