Abstract
Description
Technical Field
[0001] This utility model belongs to the field of auxiliary reading and writing tools, specifically relating to a light-diffusing structure for a reading and writing station and the reading and writing station itself. Background Technology
[0002] In optical devices such as image reading and writing stations, the light-diffusing sheet is a key component. Its core function is to improve display quality by uniformly distributing light, while also achieving heat dissipation through through-holes. In existing technologies, the through-holes of the light-diffusing sheet mostly adopt a regularly arranged square hole design to balance heat dissipation efficiency and ease of structural processing.
[0003] However, existing light-diffusing plates typically use a single row of equally spaced square heat dissipation holes (e.g., hole spacing of 4mm). While their right-angled edges and regular structure can achieve efficient heat dissipation, the right-angled edges of the square holes will produce strong specular reflection under light illumination. The reflected light propagates in a fixed direction and forms regular striped yellow spots on the surface of the book under the reading / writing station (e.g., Figure 1 (As shown). This yellow spot not only disrupts the uniformity of light but also interferes with the user's visual perception, especially when reading, potentially causing distraction or eye strain.
[0004] Furthermore, the existing square heat dissipation hole design of the light-diffusing sheet makes it difficult to balance heat dissipation efficiency and structural strength, and the resulting yellow spot problem severely restricts the user experience of the reading and writing station. Therefore, there is an urgent need for a new generation of light-diffusing sheet through-hole design that can both improve structural strength and completely eliminate yellow spots. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a uniform light structure and a reading / writing station in light of the existing technology.
[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a light-diffusing structure for a reading and writing station is proposed, comprising: a light-diffusing sheet body, on which multiple through holes are provided;
[0007] The through-hole is an irregular reflection hole, and the edge of each irregular reflection hole has a continuous nonlinear transition structure so that the incident light is diffusely reflected at the edge of the hole.
[0008] In the above-mentioned light-diffusing structure for a reading and writing station, the light-diffusing sheet body is provided with at least two rows of irregularly arranged reflective holes to enhance the structural strength of the light-diffusing sheet and disrupt the periodicity of the reflection path.
[0009] In the aforementioned uniform light structure for a reading and writing station, the irregular reflective holes in a single row are arranged in a regular pattern.
[0010] In the aforementioned uniform light structure for a reading and writing station, the irregular reflective holes in a single row are arranged irregularly.
[0011] In the aforementioned uniform light structure for a reading and writing station, the irregular reflective aperture is a circular aperture with a diameter of 2 to 6 millimeters.
[0012] In the aforementioned uniform light structure for a reading and writing station, the minimum distance between two adjacent irregular reflective holes is not less than 6 mm.
[0013] In the above-mentioned uniform light structure for a reading and writing station, the irregular reflective hole is a polygonal hole with a number of sides of not less than 6 and the edges are rounded.
[0014] In the above-mentioned uniform light structure for a reading and writing station, the irregular reflective aperture is a randomly shaped aperture with at least one wavy or serrated structure on its edge.
[0015] In the above-mentioned uniform light structure for a reading and writing station, in the double-row staggered layout of the irregular reflective holes, the lateral spacing and longitudinal spacing of adjacent rows of through holes are equal and not less than 8 mm.
[0016] This utility model solves the above-mentioned technical problems and also proposes a reading and writing station, including the above-mentioned uniform light structure for the reading and writing station.
[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] (1) By setting irregular reflection holes on the light uniform sheet body, the light emitted by the light source forms a diffuse reflection effect instead of concentrated reflection. In this way, the probability of specular reflection can be effectively reduced, thereby eliminating or significantly suppressing the macula, while improving the uniformity of light on the desktop and optimizing the user's visual experience.
[0019] (2) By setting at least two rows of irregularly arranged reflection holes on the light homogenizer body, the regularity of the single row of holes is disrupted, so that the reflection path of light between different holes no longer has symmetry or periodicity; in this way, the direction and intensity distribution of reflected light become more random, thereby avoiding the formation of regular strip-shaped yellow spots; at the same time, the staggered arrangement also helps to enhance the structural strength of the light homogenizer and prevent it from breaking.
[0020] (3) By selecting a circular hole as the through hole, its continuous curved edge can achieve the maximum diffuse reflection effect, thereby completely eliminating the yellow spot phenomenon caused by specular reflection. Its symmetrical structure helps the uniform distribution of light, improves optical performance while taking into account heat dissipation efficiency, and provides standardized support for subsequent processing technology (such as drilling and stamping). Attached Figure Description
[0021] Figure 1 This is a schematic diagram illustrating the principle of forming a yellow spot using a square hole in existing technology.
[0022] Figure 2 This is a plan view of a uniform light structure for a reading and writing station according to the present invention.
[0023] In the diagram, 100 represents the light-diffusing plate body; 200 represents the through hole. Detailed Implementation
[0024] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0025] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.
[0026] like Figure 1 The diagram illustrates the principle behind the appearance of yellow spots after setting square through-holes on a light-diffusing plate in existing technology. Specifically, a single row of square holes, due to their right-angled edges and regular arrangement (e.g., equidistant distribution), causes light to be reflected regularly on the sidewalls of the holes. This reflection path is highly symmetrical and periodic, easily forming regular strip-shaped light spots (i.e., alternating bright and dark streaks) on a tabletop. This is because the right-angled edges of the square holes produce a mirror-like reflection effect, causing light to be reflected at the same angle when passing through both sides of the hole, resulting in the reflected light concentrating in a specific direction (e.g., a straight line on the tabletop), thus forming strip-shaped light spots. Regarding the relationship between the hole spacing and the reflection path: the spacing between the square holes in a single row (e.g., 4 mm) determines the periodic distribution pattern of the reflected light. If the hole spacing happens to match the light wavelength or light source characteristics, the visibility of these yellow spots will be further enhanced.
[0027] like Figure 2 As shown, in order to solve the above problems, the present invention proposes a light-diffusing structure for a reading and writing station, comprising: a light-diffusing sheet body 100, on which a plurality of through holes 200 are provided; the through holes 200 are irregular reflection holes, and the edge of each irregular reflection hole has a continuous nonlinear transition structure so that the incident light is diffusely reflected at the edge of the hole.
[0028] Specifically, irregular reflective apertures, due to their structure and the continuous non-linear transition of their edges, significantly reduce the directional consistency of reflected light. This design makes the light source ( Figure 1The light emitted by the LED beads creates a diffuse reflection effect, rather than a concentrated reflection. In this way, the probability of specular reflection can be effectively reduced, thereby eliminating or significantly suppressing yellow spots (such as striped light spots on the surface of a book), while improving the uniformity of light on the desktop and optimizing the user's visual experience.
[0029] It is worth noting that the irregular reflective aperture in this scheme emphasizes its irregular reflection characteristics of light, rather than specifically limiting whether its shape itself is irregular.
[0030] Furthermore, the light-diffusing sheet body 100 is provided with at least two rows of irregularly arranged reflection holes to enhance the structural strength of the light-diffusing sheet and disrupt the periodicity of the reflection path.
[0031] In this design, at least two rows of irregularly arranged, staggered reflective apertures are provided on the light-diffusing sheet body 100 to disrupt the regularity of a single row of apertures, making the reflection paths of light between different apertures no longer symmetrical or periodic. This results in a more random distribution of the direction and intensity of the reflected light, thus avoiding the formation of regular striped yellow spots. Simultaneously, the staggered arrangement also helps to enhance the structural strength of the light-diffusing sheet, preventing it from breaking.
[0032] In one embodiment, the irregular reflective apertures in a single row are arranged in a regular pattern, meaning that the spacing between two adjacent irregular reflective apertures is equal.
[0033] In another embodiment, the irregular reflective apertures in the single row are arranged irregularly, meaning the spacing between two adjacent irregular reflective apertures is randomly set. This irregular arrangement further disrupts the reflection path, making the light distribution on the desktop more uniform, suitable for applications requiring high visual detail.
[0034] In one embodiment, the irregular reflective aperture is a circular aperture with a diameter of 2 to 6 millimeters, and the minimum distance between two adjacent irregular reflective apertures is not less than 6 millimeters.
[0035] The continuous curved edges of the circular aperture maximize diffuse reflection, thus completely eliminating the yellow spot phenomenon caused by specular reflection. Its symmetrical structure contributes to the uniform distribution of light, improving optical performance while ensuring heat dissipation efficiency, and providing standardized support for subsequent processing techniques such as drilling and stamping.
[0036] By setting a minimum spacing of 6mm between adjacent holes, heat dissipation performance is ensured while the structural strength of the light-diffusing sheet is enhanced, preventing breakage due to excessive porosity. The spacing design matches the hole diameter range (2-6mm) to ensure the stability and durability of the light-diffusing sheet during long-term use.
[0037] In another embodiment, the irregular reflective aperture is a polygonal aperture with at least 6 sides and rounded edges.
[0038] Using polygonal apertures (with at least 6 sides and rounded edges) as irregular reflective apertures retains the structural strength advantages of polygons (such as the honeycomb-like compressive strength of hexagons) while reducing the probability of specular reflection from right-angled edges through rounded corners. This design balances heat dissipation, structural strength, and optical performance, making it suitable for scenarios with high requirements for mechanical performance.
[0039] In yet another embodiment, the irregular reflective aperture is a randomly shaped aperture with at least one wavy or serrated structure on its edge.
[0040] Multiple angles of incident light (as shown in the attached image) Figure 1 In the case shown, random-shaped apertures can disperse light over a wider angular range through multi-directional scattering at the edges. Furthermore, random-shaped apertures with wavy or serrated edges not only completely eliminate yellow spots but also give the product a unique visual appeal, enhancing its aesthetic attractiveness and drawing consumer attention to reading stations equipped with such light-diffusing plates.
[0041] It is worth mentioning that in the double-row staggered layout of the irregular reflective apertures, the horizontal spacing and vertical spacing of the two adjacent rows of through holes 200 are equal and not less than 8 mm.
[0042] When the lateral spacing (X-axis) and longitudinal spacing (Y-axis) between two adjacent rows of holes are equal, the scattering distribution of light on the light homogenizer is more uniform and discrete, effectively avoiding overlap and interference between the reflected light from multiple holes. At the same time, a spacing of not less than 8 mm not only ensures uniform illumination but also avoids a decrease in homogenization efficiency caused by excessively large spacing (such as more than 10 mm).
[0043] This solution also proposes a reader / writer station, including the aforementioned light-diffusing structure for the reader / writer station.
