Description
Technical Field
[0001] This utility model belongs to the field of reading and writing station technology, specifically relating to a lighting structure for a reading and writing station and the reading and writing station itself. Background Technology
[0002] A reading and writing desk is an assistive device designed specifically for reading, writing, or close-range work, typically used by students, office workers, or in situations requiring prolonged eye use. Its core functions include: basic support: providing a stable surface for placing books, tablets, and other reading materials; optical enhancement: projecting the content of the reading material as a distant virtual image (3-8 meters) through a built-in optical system (such as the beam splitter and concave mirror in patent CN119902376B), achieving the effect of "seeing near as far," reducing the burden on the eyes' accommodation, and thus slowing the progression of myopia.
[0003] Existing reading desks typically employ a lighting structure parallel to the placement area (i.e., the surface on which the reading material is placed). The light-emitting units (such as LED strips or fluorescent tubes) are directly installed above the reading desk, and the light shines vertically or nearly vertically onto the placement area. However, this traditional lighting scheme has the following technical defects: (1) Insufficient illumination in the central area. Because the light-emitting units are parallel to the placement area, the incident angle of the light at the center of the placement area is too large, resulting in uneven light intensity distribution. Specifically, the edge areas of the placement area are brighter due to direct light, while the central area is relatively dark due to insufficient light superposition. This easily leads to a central dark spot during imaging, affecting the uniformity of reading or image acquisition; (2) Limited coverage area. The parallel-arranged light-emitting units need to increase the power or number of light sources to expand the illumination range. However, due to limitations in installation space and heat dissipation requirements, their effective coverage area can usually only match standard-sized reading materials (such as A4 paper). When placing larger reading materials (such as A3 size or unfolded books), the edge areas are prone to illumination attenuation, failing to completely cover the readable area of the reading material, resulting in blurred image edges or loss of detail.
[0004] Therefore, there is an urgent need for a reading and writing station lighting structure that can simultaneously solve the problem of central darkness and expand the coverage area. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a lighting 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 problem is as follows: A lighting structure for a reading / writing station is proposed, wherein a placement area is provided on the reading / writing station for placing reading materials, and the lighting structure is used to illuminate the reading materials placed in the placement area. The lighting structure includes:
[0007] The first and second light-emitting units, positioned opposite each other above the placement area, emit light that completely covers the readable area of the reading material; wherein...
[0008] The light-emitting surfaces of the first and second light-emitting units are both inclined toward the placement area, so that the effective coverage area of the light emitted by the first and second light-emitting units completely covers the readable range of the reading material, and so that the light from the two units at the middle part of the readable range forms an overlapping area.
[0009] In the above-described lighting structure for a reading and writing station, the luminous surface of the first luminous unit forms a first tilt angle with the placement area, and the luminous surface of the second luminous unit forms a second tilt angle with the placement area, wherein the first tilt angle and the second tilt angle are equal.
[0010] In the above-described lighting structure for a reading and writing station, the luminous surface of the first luminous unit forms a first tilt angle with the placement area, and the luminous surface of the second luminous unit forms a second tilt angle with the placement area, wherein the first tilt angle and the second tilt angle are not equal.
[0011] In the above-mentioned lighting structure for a reading and writing station, the values of the first tilt angle and the second tilt angle are both in the range of 2° to 8°.
[0012] In the above-mentioned lighting structure for a reading and writing station, the intersection of the optical axes of the first light-emitting unit and the second light-emitting unit is located 65mm-75mm above the placement area.
[0013] In the above-described lighting structure for a reading / writing station, the reading / writing station includes a platform frame disposed above the placement area, and both the first light-emitting unit and the second light-emitting unit include:
[0014] A strip light source module is obliquely disposed on the platform frame to form the light source for the first light-emitting unit and the second light-emitting unit. The end face of the strip light source module facing the placement area forms the light-emitting surface.
[0015] A light-transmitting protective cover is connected to the platform frame and forms a mounting cavity for placing the strip light source module between the cover and the platform frame.
[0016] In the above-mentioned lighting structure for a reading and writing station, a plurality of parallel partitions are provided in the mounting cavity, and the plane of each partition is consistent with the tilt angle of the strip light source module. The strip light source module is fixed to the station frame by a connector.
[0017] In the above-mentioned lighting structure for a reading and writing station, the edge of the partition is provided with a light-shielding wing extending toward the light-transmitting protective cover, and the light-shielding wings on the same partition form a stray light prevention channel.
[0018] In the above-mentioned lighting structure for a reading and writing station, the surface of the light-transmitting protective cover is provided with an array of heat dissipation holes. The geometry of each heat dissipation hole is an elongated oval, and its major axis is parallel to the extension direction of the strip light source module.
[0019] This utility model solves the above-mentioned technical problems and also proposes a reading and writing station, including the above-mentioned lighting structure for the reading and writing station.
[0020] Compared with the prior art, the present invention has the following beneficial effects:
[0021] (1) By symmetrically setting the first light-emitting unit and the second light-emitting unit above the placement area and arranging their light-emitting surfaces at an angle toward the placement area, the light is projected onto the surface of the reading material at a certain angle. This design changes the defect of insufficient light intensity superposition in the central area caused by the vertical incidence of light in traditional parallel lighting.
[0022] (2) By making the first tilt angle equal to the second tilt angle, an optical layout of symmetrical illumination of the light-emitting units on the left and right sides is achieved. This symmetrical structure ensures that the light is evenly distributed on both sides of the central axis of the placement area, avoiding illumination shift or asymmetry of brightness caused by angle differences, further optimizing the light intensity consistency of the middle superimposed area, and improving the symmetry and uniformity of the overall illuminance.
[0023] (3) The design that allows the first tilt angle to be different from the second tilt angle provides greater lighting flexibility and can be asymmetrically adjusted according to the placement of the reading material, user habits or the space constraints of the table structure.

Detailed Implementation
[0032] 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.
[0033] 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.
[0034] like Figures 1 to 7 As shown, the present invention provides an illumination structure for a reading and writing station and a reading and writing station, comprising: a first light-emitting unit 310 and a second light-emitting unit 320.
[0035] Specifically, the reading and writing table is provided with a placement area 200 for placing reading materials. The lighting structure 300 is used to illuminate the reading materials placed in the placement area 200. The lighting structure 300 includes a first light-emitting unit 310 and a second light-emitting unit 320 positioned opposite each other above the placement area 200. The light 390 emitted by the first light-emitting unit 310 and the second light-emitting unit 320 completely covers the readable area of the reading materials. The light-emitting surfaces of the first light-emitting unit 310 and the second light-emitting unit 320 are both inclined towards the placement area 200 so that the effective coverage area of the light 390 emitted by the first light-emitting unit 310 and the second light-emitting unit 320 completely covers the readable area of the reading materials, and so that the light 390 of the two units at the middle part of the readable area forms an overlapping area.
[0036] In this solution, the readable area refers to the effective display area of the reading material, which can be a physical book or an electronic device such as a tablet computer. Figure 1 A schematic diagram comparing the light 390 distribution of a conventional reading / writing station lighting structure 300 and the lighting structure 300 of this application in their working state is shown. It can be seen that by tilting the light-emitting surfaces of the first light-emitting unit 310 and the second light-emitting unit 320 relative to the placement area 200, the emitted light 390, compared to the nearly perpendicular light 390' in the conventional structure, not only significantly expands the overall illumination range but also forms a wider overlapping area of light 390 in the center of the readable area, making the central area of the reading material brighter and effectively solving the problems of small coverage and insufficient light in the central area inherent in traditional lighting.
[0037] In this design, a first light-emitting unit 310 and a second light-emitting unit 320 are symmetrically arranged above the placement area 200, with their light-emitting surfaces tilted towards the placement area 200, so that light 390 is projected onto the reading surface at a certain angle. This design overcomes the deficiency of insufficient light intensity superposition in the central area caused by the perpendicular incidence of light 390 in traditional parallel lighting. The beams of the tilted light sources on both sides intersect and superimpose in the middle of the readable area, significantly enhancing the illuminance of this area, effectively eliminating the "central dark spot," and achieving high uniformity of overall lighting. At the same time, the tilted arrangement also widens the effective illumination angle of a single light-emitting unit, allowing light 390 to cover a larger area of the reading surface, effectively solving the problem of illuminance attenuation and incomplete coverage in the edge areas of traditional structures.
[0038] In one embodiment, the light-emitting surface of the first light-emitting unit 310 forms a first tilt angle 330 with the placement area 200, and the light-emitting surface of the second light-emitting unit 320 forms a second tilt angle 340 with the placement area 200, wherein the first tilt angle 330 and the second tilt angle 340 are equal.
[0039] In this design, by making the first tilt angle 330° equal to the second tilt angle 340°, a symmetrical illumination optical layout of the left and right light-emitting units is achieved. This symmetrical structure ensures that the light rays 390° are evenly distributed on both sides of the central axis of the placement area 200, avoiding illumination shifts or asymmetry in brightness caused by angular differences. This further optimizes the light intensity consistency of the central superimposed area and improves the symmetry and uniformity of the overall illuminance. Furthermore, the symmetrical design simplifies the structural assembly and optical debugging process, which is beneficial for quality control in mass production and improves product consistency and reliability.
[0040] In another embodiment, the light-emitting surface of the first light-emitting unit 310 forms a first tilt angle 330 with the placement area 200, and the light-emitting surface of the second light-emitting unit 320 forms a second tilt angle 340 with the placement area 200. The first tilt angle 330 and the second tilt angle 340 are not equal.
[0041] This design, which allows for unequal first tilt angles 330° and second tilt angles 340°, provides greater lighting flexibility, enabling asymmetrical adjustments based on the placement of reading materials, user habits, or spatial limitations of the tabletop structure. For example, if optical components or supports obstruct one side of the reading / writing table, the tilt angle of the light-emitting unit on the other side can be adjusted to compensate for the light distribution and maintain overall lighting uniformity. This design enhances the adaptability of the lighting structure 300 to complex structural environments, enabling personalized and customized lighting solutions and expanding the product's application scenarios.
[0042] Preferably, the first tilt angle 330 and the second tilt angle 340 are both in the range of 2° to 8°. The intersection 350 of the optical axes of the first light-emitting unit 310 and the second light-emitting unit 320 is located 65mm-75mm above the placement area 200.
[0043] In this design, the intersection 350 refers to the spatial point where the light rays 390 emitted by the first light-emitting unit 310 and the second light-emitting unit 320 intersect. (Refer to...) Figure 1 In this design, the height of the light beam intersection point (350') is significantly higher than the original height (400') of the intersection point (350') in the traditional lighting structure. This ensures that the light intensity superposition area falls precisely within the frequently used reading area in the center of the book, thereby maximizing the brightness and illuminance uniformity of key areas. This design avoids the problems of the superposition area being too far from the book surface and the lighting effect weakening due to an excessively high intersection point, or localized overbrightness or even bright spots due to an excessively low intersection point. It optimizes optical performance and ensures high-quality, stable lighting output.
[0044] It is worth mentioning that the reading and writing station includes a platform frame 100 disposed above the placement area 200. The first light-emitting unit 310 and the second light-emitting unit 320 each include: a strip light source module 360, which is obliquely disposed on the platform frame 100 to form the light source of the first light-emitting unit 310 and the second light-emitting unit 320, and the end face of the strip light source module 360 facing the placement area 200 forms a light-emitting surface; and a light-transmitting protective cover 370, which is connected to the platform frame 100 and forms a mounting cavity 130 for placing the strip light source module 360 between the cover and the platform frame 100.
[0045] In one embodiment, the side of the platform frame 100 facing the placement area 200 has a quadrilateral structure, with the lighting structure 300 of this solution provided on both sets of opposite sides. This solution employs an integrated design combining the strip light source module 360 with the platform frame 100 and the light-transmitting protective cover 370. This not only achieves stable tilting installation of the light-emitting unit but also forms a closed mounting cavity 130, effectively preventing dust and electric shock, thus improving safety and durability. The strip light source has good directionality and extensibility, making it easy to arrange along the long side of the reading material for large-area uniform illumination; the light-transmitting protective cover 370 helps soften the emitted light 390, reducing direct glare. The overall structure is compact, easy to assemble and maintain, and balances functionality with aesthetic industrial design, enhancing the product's practicality and user experience.
[0046] Furthermore, the cavity is provided with multiple parallel partitions 110, the plane of each partition 110 is at the same tilt angle as the strip light source module 360, and the strip light source module 360 is fixed to the platform frame 100 by the connector 140.
[0047] A parallel partition 110, with an angle consistent with the 360° tilt of the strip light source module, is installed within the mounting cavity 130. The light source module is then secured via a connector 140, significantly improving the accuracy and stability of the light source installation. The partition 110 serves as a positioning reference, ensuring that each light source module maintains a consistent tilt angle, preventing angular deviations due to vibration or thermal expansion and contraction during use, thus guaranteeing long-term lighting uniformity. Simultaneously, the multi-partition 110 structure enhances the mechanical strength of the mounting cavity 130, improving heat dissipation and structural durability, and extending the equipment's lifespan.
[0048] Preferably, the connector 140 is a bolt, which is threadedly connected to the platform frame 100.
[0049] The edge of the partition 110 is provided with a light-shielding wing 120 extending toward the light-transmitting protective cover 370, and the light-shielding wings 120 on the same partition 110 form a stray light prevention channel.
[0050] A light-shielding wing 120 extending towards the light-transmitting protective cover 370 is provided at the edge of the partition 110, forming a stray light prevention channel. This effectively blocks non-functional stray light emitted from the side and back of the light source module, preventing it from escaping directly or reflecting multiple times inside the platform to form glare or halo, interfering with the user's vision or affecting image quality (especially in reading and writing stations equipped with camera or projection functions). This design improves the directional control precision of the emitted light beam 390, making the main beam more focused and pure, enhancing illumination contrast and clarity, and further optimizing visual comfort and optical system performance.
[0051] Preferably, the surface of the light-transmitting protective cover 370 is provided with an array of heat dissipation holes 380, and the geometry of a single heat dissipation hole 380 is an elongated oval, with its major axis parallel to the extension direction of the strip light source module 360.
[0052] The surface of the light-transmitting protective cover 370 features an array of elongated oval-shaped heat dissipation holes 380, with the long axis of the holes aligned with the extension direction of the strip light source module 360, forming a highly efficient directional heat dissipation channel. This design caters to the characteristic of the strip light source generating heat along its length, promoting rapid longitudinal convection and preventing heat accumulation that could lead to LED light decay or reduced lifespan. Compared to circular holes, the elongated oval holes offer a larger effective ventilation area at the same aperture ratio, and their array distribution ensures uniform overall heat dissipation. This structure significantly improves heat dissipation efficiency without compromising structural strength or dustproof performance, ensuring long-term stable operation of the light source and extending the lifespan of the lighting system.
[0053] This solution also proposes a reading and writing station, including the aforementioned lighting structure 300.
