Description

Technical Field

[0001] This application relates to the field of vehicle lighting technology, specifically to a lighting fixture with a specific anti-glare structure. Background Technology

[0002] With the rapid development of the rail train industry at home and abroad, the lighting requirements for carriages are no longer limited to illuminance. Instead, they are trending towards stable, uniform, and glare-free interior lighting. A good anti-glare environment can significantly improve visual comfort and reduce visual fatigue and discomfort caused by glare.

[0003] To prevent visual fatigue, discomfort, or even temporary blindness in passengers and drivers due to sudden changes in light or glare from lighting fixtures, and to ensure safety, the application of anti-glare lighting fixtures in high-speed trains is an inevitable result of the development of modern rail transit lighting technology. Poorly designed lighting fixtures can easily produce stray light and direct glare when multiple light sources overlap, affecting the overall lighting environment. Anti-glare design can effectively control the direction of light and reduce light pollution.

[0004] Therefore, anti-glare structures play a crucial role in high-speed rail systems, with applications spanning multiple key areas such as passenger carriages and driver's cabs. The core objectives are to ensure driving safety, enhance passenger comfort, and optimize the visual environment. In high-speed rail systems, the application of anti-glare structures reflects a design philosophy that prioritizes both safety and comfort: in the driver's cab, anti-glare is a fundamental safety requirement, directly impacting train operation and demanding the highest technical standards; in passenger areas, anti-glare is key to improving service quality and passenger experience, creating a quiet, comfortable, and undisturbed lighting environment. Anti-glare lighting fixtures successfully achieve a perfect combination of high luminous efficiency, long lifespan, glare-free operation, and high uniformity, creating a safe, comfortable, and healthy lighting environment for passengers and drivers, becoming an important embodiment of the modern high-speed rail's "people-oriented" design philosophy.

[0005] In summary, to meet practical needs, a lamp with a specific anti-glare structure is provided. Summary of the Invention

[0006] To address the shortcomings of existing technologies, the purpose of this application is to provide a lamp with a specific anti-glare structure, which improves lighting quality, effectively enhances visual comfort, and reduces eye fatigue based on a lampshade, LED panel, and light-shielding plate with a specific structure.

[0007] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0008] A specific anti-glare structure for a lamp, the lamp comprising:

[0009] The lamp body has a built-in driver power supply;

[0010] An arc-shaped lampshade is provided on the bottom surface of the main body of the lamp;

[0011] A light-shielding plate covering the bottom surface of the curved lampshade;

[0012] A light-emitting component is built into the curved lampshade, and the light-emitting component is electrically connected to the driving power supply; wherein...

[0013] The arc-shaped lampshade is a columnar structure with an arc-shaped cross-section;

[0014] The top surface of the arc-shaped lampshade is connected to the bottom surface of the lamp body;

[0015] The light-shielding plate is an arc-shaped plate, and its size is larger than the bottom surface of the arc-shaped lampshade.

[0016] Based on the above technical solution, the light-emitting component is an LED light panel with an arc-shaped plate structure.

[0017] Based on the above technical solution, the light-emitting component is disposed inside the arc-shaped lampshade along the arc-shaped contour of the lampshade.

[0018] Based on the above technical solution, a middle partition is provided between the bottom surface of the lamp body and the top surface of the arc-shaped lampshade;

[0019] The size of the intermediate partition is larger than the bottom surface size of the lamp body and the top surface size of the arc-shaped lampshade.

[0020] Compared with the prior art, the advantages of this application are:

[0021] Improve visual comfort and reduce eye strain. Passengers will not see any glaring light sources, whether seated or standing.

[0022] Improve lighting quality and create a more pleasant lighting environment. Uniform, continuous, and soft light illuminates the entire carriage, creating a comfortable atmosphere.

[0023] Enhance the aesthetics and modernity of the lighting fixtures;

[0024] By employing a concealed light source design, light-blocking angle control, and matte surface treatment, the system improves light utilization efficiency and enhances the visual environment, thereby achieving more efficient and comfortable lighting at the system level.

[0031] The embodiments of this application will be further described in detail below with reference to the accompanying drawings.

[0032] This application provides a lamp with a specific anti-glare structure. Based on the lampshade, LED light panel and light shield of a specific structure, it improves lighting quality, effectively enhances visual comfort and reduces eye fatigue.

[0033] To achieve the aforementioned technical effects, the overall concept of this application is as follows:

[0034] A specific anti-glare structure for a lamp, the lamp comprising:

[0035] The lamp body 1 has a built-in driver power supply;

[0036] An arc-shaped lampshade 2 is provided on the bottom surface of the lamp body 1;

[0037] The light-shielding plate 3 covers the bottom surface of the curved lampshade 2;

[0038] A light-emitting component 4 is built into the arc-shaped lampshade 2, and the light-emitting component 4 is electrically connected to the driving power supply; wherein...

[0039] The arc-shaped lampshade 2 is a columnar structure with an arc-shaped cross-section;

[0040] The top surface of the arc-shaped lampshade 2 is connected to the bottom surface of the lamp body 1;

[0041] The light-shielding plate 3 is an arc-shaped plate, and its size is larger than the bottom surface of the arc-shaped lampshade 2.

[0042] The embodiments of this application will be further described in detail below with reference to the accompanying drawings.

[0043] See Figures 1-2 As shown in the figure, this application embodiment provides a lamp with a specific anti-glare structure, the lamp comprising:

[0044] The lamp body 1 has a built-in driver power supply;

[0045] An arc-shaped lampshade 2 is provided on the bottom surface of the lamp body 1;

[0046] The light-shielding plate 3 covers the bottom surface of the curved lampshade 2;

[0047] A light-emitting component 4 is built into the arc-shaped lampshade 2, and the light-emitting component 4 is electrically connected to the driving power supply; wherein...

[0048] The arc-shaped lampshade 2 is a columnar structure with an arc-shaped cross-section;

[0049] The top surface of the arc-shaped lampshade 2 is connected to the bottom surface of the lamp body 1;

[0050] The light-shielding plate 3 is an arc-shaped plate, and its size is larger than the bottom surface of the arc-shaped lampshade 2.

[0051] In this embodiment, the lampshade, LED light panel, and light-shielding plate with a specific structure improve lighting quality, effectively enhance visual comfort, and reduce eye fatigue.

[0052] The technical solutions of this application effectively reduce or eliminate visual discomfort and glare caused by high-brightness light sources or strong brightness contrast. Anti-glare design is crucial for improving visual comfort, reducing light pollution, and protecting eyesight.

[0053] Furthermore, the light-emitting component 4 is an LED light panel with an arc-shaped plate structure.

[0054] Specifically, the LED light panel includes multiple LED beads arranged in a matrix.

[0055] Furthermore, the light-emitting component 4 is disposed within the arc-shaped lampshade 2 along the arc-shaped contour of the arc-shaped lampshade 2.

[0056] Furthermore, a middle partition 5 is provided between the bottom surface of the lamp body 1 and the top surface of the arc-shaped lampshade 2;

[0057] The size of the intermediate partition 5 is larger than the bottom surface size of the lamp body 1 and the top surface size of the arc-shaped lampshade 2.

[0058] To overcome the shortcomings of existing technologies, the technical solution of this application embodiment can achieve "light without lamp," with zero glare from the lamps, alleviating passenger fatigue and improving the passenger travel experience. While meeting the requirements of lighting functions (illuminance, uniformity, color rendering) and energy efficiency, it minimizes or eliminates direct and reflected glare to the greatest extent possible, providing a comfortable and healthy visual environment.

[0059] This anti-glare design has a simple structure that is integrated into the lamp structure, eliminating the need for remanufacturing or secondary installation, thus greatly facilitating future maintenance.

[0060] With a concealed light source design, the LED beads are hidden deep within the lamp cavity. From a conventional perspective inside the carriage, the luminous LED chips or solder joints cannot be seen directly; only the soft light after reflection or diffusion can be seen.

[0061] The technical solution of this application not only provides a wider illumination width in terms of function, but also has an arc-shaped design, making it stylish and beautiful. No screws or cables are visible from the passenger's perspective.

[0062] The light-shielding plate 3 is made of aluminum alloy and serves as both the structural support for the lamp panel and a heat sink to ensure stable LED luminous efficacy. This component is manufactured using a die-casting process and undergoes matte black oxidation or spray coating treatment to achieve low reflectivity.

[0063] The curved lampshade 2 is made of high-transmittance polycarbonate material and uses injection molding process to ensure the consistency and precision of optical components. The surface is frosted to convert specular reflection into diffuse reflection, which increases the softness of the lampshade's illumination and makes the transmitted light uniform and soft.

[0064] The main body of the lamp 1 has an embedded driver power supply, which uses DALI to adjust the brightness of the lamp (such as when entering or exiting a tunnel), maintain a constant and comfortable illuminance, reduce discomfort caused by the contrast between light and dark, and indirectly assist in anti-glare.

[0065] The light-emitting component 4 is composed of an irregularly shaped LED light panel. The small size of the LEDs facilitates integration into various lighting fixture structures, providing a foundation for concealed and modular designs. To control the light emission angle and prevent direct light from entering passengers' eyes, the light panel is installed at an angle. The fixing method is a combination of magnetic attraction and mechanical limiting. Magnetic attraction: Magnets are embedded on the back of the light panel, and ferromagnetic material or another set of magnets are located at corresponding positions on the lamp body, securing it through magnetic attraction. Mechanical limiting: The lower slot of the light-shielding component 1 limits sliding or detachment. The lower part of the light panel acts as a clip, with corresponding slots designed on the lamp body, achieving a quick "click" installation through elastic deformation.
