[0033] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0034] like Figures 1 to 6 As shown, the first embodiment of the utility model provides a lighting fixture, including:

[0035] A substrate 100, on which a plurality of mounting grooves 102 are formed;

[0036] The mounting seat 104 is mounted in the mounting groove 102 in a one-to-one correspondence with the mounting groove 102;

[0037] The lamp body 106 is mounted on the mounting base 104;

[0038] When the lighting fixture is installed in a rail vehicle, the base plate 100 is used as an interior ceiling of the rail vehicle.

[0039] According to the lighting fixture provided by the embodiment of the first aspect of the utility model, by directly opening the mounting grooves 102 on the substrate 100 and installing the mounting seats 104 in these mounting grooves 102 in a one-to-one correspondence, the lighting fixture and the substrate 100 are closely combined. This integrated design not only simplifies the installation process of the lighting fixture, but also improves the structural stability between the lamp body 106 and the mounting seat 104 and between the mounting seat 104 and the substrate 100. Since the lamp body 106 is installed on the mounting seat 104, when the lamp body 106 fails or needs to be replaced, the lamp body 106 can be easily disassembled and replaced without large-scale disassembly and reinstallation of the entire lighting fixture. This greatly simplifies the maintenance and replacement process and improves maintenance efficiency. In the case where the lighting fixture is installed on a rail vehicle, the substrate 100 can be directly used as the interior roof of the rail vehicle. This design not only reduces the complexity of the internal structure of the rail vehicle, but also makes the lighting fixture more coordinated and unified with the interior decoration style of the vehicle, thereby improving the overall aesthetics. Since the combination of the substrate 100, the mounting base 104, and the lamp body 106 is highly flexible, this lighting fixture can adapt to rail vehicles of different models and sizes. At the same time, the material and design of the substrate 100 can also be adjusted according to the specific environment and needs inside the vehicle to adapt to different usage environments. Through the tight combination between the mounting base 104 and the substrate 100 and the lamp body 106 and the mounting base 104, the lighting fixture is not easy to loosen or fall off during the operation of the rail vehicle, thereby ensuring the safety of the passengers. In addition, through reasonable circuit design and protective measures, safety hazards such as electrical failures or fires during the use of the lamp can also be effectively prevented.

[0040] Please continue to see Figures 1 to 6 In the lighting fixture provided in the embodiment of the first aspect of the utility model, it is mainly composed of three parts: a substrate 100, a mounting base 104 and a lamp body 106.

[0041] The substrate 100 is the basic component of the entire lighting fixture, and a plurality of mounting grooves 102 are provided on the substrate 100. These mounting grooves 102 are carefully arranged according to the design requirements of the lighting fixture and the number and size of the mounting seats 104, ensuring that each mounting seat 104 can be firmly mounted on the substrate 100. The material of the substrate 100 is usually selected to have a certain strength and rigidity to ensure that it can withstand the weight of the lighting fixture and the external force it is subjected to, such as corrugated board, corrugated board, etc.

[0042] The mounting seat 104 corresponds to the mounting groove 102 on the base plate 100 and is fixed in the mounting groove 102 by an appropriate connection method (such as bolt connection, snap connection, etc.). The design of the mounting seat 104 takes into account the load-bearing and stability of the lamp, and also facilitates the installation and removal of the lamp body 106.

[0043] Through the corresponding relationship between the mounting seat 104 and the mounting groove 102, a stable connection between the various components of the lamp is achieved, ensuring the stability and reliability of the lamp during use. The one-to-one correspondence between the mounting seat 104 and the mounting groove 102 simplifies the installation process of the lamp and improves the installation efficiency. At the same time, the detachable design of the lamp body 106 on the mounting seat 104 also facilitates the maintenance and replacement of the lamp.

[0044] The lamp body 106 is the core component of the lighting fixture, responsible for emitting light to provide lighting. The lamp body 106 is mounted on the mounting base 104, and the lighting direction and range of the lamp body 106 can be changed by adjusting the position and angle of the mounting base 104. The lamp body 106 can be selected according to actual needs, such as LED lamps, fluorescent lamps, etc., to meet different lighting needs.

[0045] When the lighting fixture is installed on a rail vehicle, the substrate 100 is not only the basic component of the lighting fixture, but also directly used as the interior ceiling of the rail vehicle. This design allows the lighting fixture to be integrated with the interior decoration of the vehicle, which not only simplifies the installation process of the lighting fixture, but also improves the overall aesthetics of the interior of the vehicle. In other words, the substrate 100, as a combination of the interior ceiling and the lighting fixture, achieves a perfect fusion of the lighting fixture and the interior decoration of the vehicle, and improves the overall aesthetics.

[0046] The design of this lighting fixture is highly flexible and can be customized according to the needs of different rail vehicles to adapt to different installation environments and lighting requirements.

[0047] According to an embodiment of the present invention, a light homogenizing plate 108 is disposed on a side of the lamp body 106 facing away from the mounting base 104 .

[0048] The main function of the light homogenizer 108 is to make the light emitted by the lamp body 106 more uniform. When the light passes through the light homogenizer 108, the microstructure inside it can diffuse and distribute the light, eliminate the phenomenon of light spots and uneven brightness, and make the lighting area more uniform and soft. Due to the effect of the light homogenizer 108, the light emitted by the lighting fixture is no longer dazzling or glaring, providing a more comfortable visual environment for passengers. Inside the rail vehicle, especially in the compartments, seats and other areas, this soft lighting effect is particularly important and helps to improve the passengers' riding experience. In addition, the light homogenizer 108 also plays a certain protective role. It can prevent dust, foreign matter, etc. from directly contacting the lamp body 106, reduce damage and pollution to the lamp body 106, and extend the service life of the lamp body 106. The light homogenizer 108 is usually made of transparent or translucent materials, such as PC boards, and its appearance and texture can be coordinated with the overall design style of the lighting fixture, further enhancing the aesthetics of the lamp.

[0049] According to an embodiment of the present invention, the light diffuser 108 is snap-fitted, interference-fitted or bonded to the mounting base 104 .

[0050] In the embodiment of the present invention, a variety of different connection structures can be used between the light diffuser 108 and the mounting base 104 .

[0051] Taking snap connection as an example, the mounting base 104 and the light diffuser 108 are respectively designed with matching snap slots and snap buckles. During installation, align the snap buckle on the light diffuser 108 with the snap slot on the mounting base 104, and then press gently to snap the snap buckle into the snap slot to achieve fixation.

[0052] Taking interference fit as an example, the size of the mounting seat 104 is slightly smaller than the light diffuser 108. When the mounting seat 104 is inserted into the reserved hole of the light diffuser 108, a certain friction force is generated due to the size difference between the two, thereby achieving a tight fit.

[0053] Taking bonding as an example, an adhesive suitable for a specific material is selected to ensure bonding strength and durability. The adhesive is applied to the contact surface of the light diffuser 108 and the mounting seat 104, and then the two are closely attached, and the adhesive is waited for to dry and solidify.

[0054] It can be seen that no matter whether it is snap-fitting, interference fit or bonding, no complicated installation steps or tools are required, making the installation process of the light diffuser 108 simple and quick.

[0055] According to one embodiment of the utility model, a first mounting hole 110 is opened at a position corresponding to the mounting groove 102 on the substrate 100, and a second mounting hole 112 is provided on the mounting seat 104. Fasteners are passed through the first mounting hole 110 and the second mounting hole 112 to install the mounting seat 104 on the mounting groove 102.

[0056] According to an embodiment of the present invention, the base plate 100 is provided with a first mounting hole 110 at a position corresponding to the mounting groove 102, and the mounting seat 104 is provided with a second mounting hole 112 corresponding to the mounting holes. Fasteners such as bolts and screws are inserted into the first mounting hole 110 and the second mounting hole 112 to securely mount the mounting seat 104 in the mounting groove 102.

[0057] The first mounting holes 110 are precisely formed around the mounting slots 102 on the substrate 100, and their positions and numbers match the second mounting holes 112 on the mounting base 104. This design ensures that the mounting base 104 can be accurately aligned with the mounting slots 102 and a secure connection is achieved through fasteners.

[0058] Select appropriate fasteners according to actual application requirements and factors such as the material and thickness of the mounting base 104. During the installation process, the fasteners pass through the first mounting hole 110 and the second mounting hole 112 in sequence, and achieve a fastened connection between the mounting base 104 and the substrate 100 by tightening.

[0059] The mounting base 104 is tightly connected to the substrate 100 by fasteners, which significantly enhances the structural stability of the entire lighting fixture. This connection method can effectively resist external vibration and impact, and ensure the stability and safety of the lamp during the operation of the rail vehicle. The design of the first mounting hole 110 and the second mounting hole 112 simplifies the installation process, so that the mounting base 104 can be quickly and accurately installed on the substrate 100. At the same time, the use of fasteners also improves the installation efficiency and reduces the installation cost. The fastener connection method allows the mounting base 104 to be easily disassembled when it needs to be repaired or replaced. This design not only improves the maintainability of the lamp, but also helps to extend the service life of the lamp. This design method has strong adaptability and can be applied to lighting fixtures and mounting bases 104 of different models and specifications. By adjusting the position and number of the mounting holes, the installation requirements of different rail vehicles for lighting fixtures can be met.

[0060] According to an embodiment of the present invention, a connecting ear 114 is disposed on the mounting seat 104 , and the second mounting hole 112 is opened in the connecting ear 114 .

[0061] See also Figure 2 A connecting ear 114 is added to the mounting base 104. The connecting ear 114 is generally designed to be a structure protruding from the surface of the mounting base 104 to provide additional support and fixing points. A second mounting hole 112 is formed on the connecting ear 114. After the fastener passes through the first mounting hole 110 of the substrate 100, it is aligned with the second mounting hole 112 located on the connecting ear 114 and fixed.

[0062] The design of the connecting ear 114 increases the connection area between the mounting base 104 and the substrate 100, thereby improving the stability of the entire lamp structure. This design can effectively reduce the shaking or deformation that may occur in the lamp during use. Since the second mounting hole 112 is opened on the connecting ear 114, the installer can locate the position of the fastener more accurately. This helps to ensure the precise alignment of the mounting base 104 and the substrate 100, and improves the accuracy and reliability of the installation. The connecting ear 114 serves as an additional support point to optimize the distribution of the lamp when it is subjected to force. When the lamp is subjected to external force, the connecting ear 114 can share part of the force and reduce the pressure on the mounting base 104 body, thereby extending the service life of the lamp. By adjusting the size, shape and position of the connecting ear 114, the design can adapt to different installation environments and needs. This makes the lighting fixture more flexible and can meet the installation requirements of various interior spaces of rail vehicles.

[0063] According to an embodiment of the present invention, mounting beams 116 are provided on both sides of the substrate 100 along the length direction of the substrate 100 .

[0064] See also Figure 1 , Figure 3 and Figure 5 The mounting beam 116 extends along the length direction of the substrate 100 and is arranged on both sides of the substrate 100. The mounting beam 116 has sufficient strength and stability to support and fix other components of the lamp. The mounting beam 116 can be firmly fixed to the substrate 100 by welding, bolting or other fastening methods. This connection method ensures the stability between the mounting beam 116 and the substrate 100 and prevents loosening or deformation that may occur during use.

[0065] The provision of the mounting beams 116 significantly enhances the overall structural stability of the substrate 100 and the entire lamp. They provide additional support and fixing points for the lamp, allowing the lamp to remain stable when subjected to external forces or vibrations, reducing the risk of deformation or damage. The design of the mounting beams 116 helps to optimize the distribution of the lamp when it is subjected to force. When the lamp is subjected to external forces, the mounting beams 116 can share part of the force and reduce the pressure on the substrate 100 and other components, thereby improving the durability and life of the lamp. By providing the mounting beams 116, the lighting fixture of the utility model can be more flexibly adapted to different installation requirements and environments. The length, position and number of the mounting beams 116 can be adjusted according to specific needs to meet the installation requirements of different interior spaces of rail vehicles.

[0066] According to an embodiment of the present invention, the mounting beam 116 is a mouth-shaped beam.

[0067] First, the design of the mouth-shaped beam allows the mounting beam 116 to have a large deformation space. Since its cross section is hollow, the mouth-shaped beam can deform to a certain extent when subjected to external forces, thereby absorbing and dispersing the impact force and protecting other parts of the lamp from damage. This feature allows the lamp to better maintain its integrity and functionality when facing collisions or vibrations.

[0068] Secondly, the design of the mouth beam helps reduce the chance of damage to the rear of the lamp. Due to its unique shape and structure, the mouth beam can disperse the force to a wider area when it is impacted, reducing the degree of local force. This not only reduces the chance of damage to the rear of the lamp, but also reduces the frequency and cost of maintenance and increases the service life of the lamp.

[0069] In addition, the mouth beam also has a high protection ability. Its solid structure and stable performance can effectively protect the electronic components and circuits inside the lamp from the external environment, such as dust, moisture, etc. This helps to ensure the normal operation and stability of the lamp and improve the passenger's riding experience.

[0070] According to an embodiment of the present invention, a plurality of lifting holes 118 are provided on the mounting beam 116 along the length direction of the mounting beam 116 .

[0071] The hoisting holes 118 are evenly distributed along the length of the mounting beam 116 to ensure stability and balance during the hoisting process. The number of hoisting holes 118 is reasonably designed according to the length of the mounting beam 116 and the overall weight of the lamp to meet the hoisting requirements. The size and shape of the hoisting holes 118 are designed according to the requirements of the hoisting equipment, usually circular or rectangular to accommodate the connection of different hoisting tools. At the same time, the edges of the hoisting holes 118 are smoothed to prevent wear or damage during the hoisting process.

[0072] By opening a hoisting hole 118 on the mounting beam 116, the hoisting of the lamp is facilitated. The hoisting equipment can easily lift the lamp and move it to the designated position by connecting the hoisting hole 118, thereby improving the installation efficiency. The provision of multiple hoisting holes 118 allows the lamp to be evenly stressed during the hoisting process, thereby avoiding deformation or damage caused by single-point stress. At the same time, the position and number of the hoisting holes 118 are carefully designed to ensure the stability and safety of the lamp during the hoisting process. The design of the hoisting holes 118 enables the lamp to adapt to different installation environments. Whether indoors or outdoors, whether high in the air or on the ground, the hoisting holes 118 can be used for convenient and quick installation. In addition, due to the presence of the hoisting holes 118, the lamp can be hoisted during disassembly, transportation and reinstallation, thereby reducing the trouble of manual handling and improving the reusability of the lamp.

[0073] According to an embodiment of the present invention, a centralized power supply is also included, and the lamp body 106 is electrically connected to the centralized power supply.

[0074] The centralized power supply is a specially designed power supply device used to provide power supply for multiple lamps or other devices. In the present invention, the centralized power supply is integrated into the lamp system to provide a stable and reliable power supply for the lamp body 106. The lamp body 106 is connected to the centralized power supply through wires or other conductive parts to ensure that power can be smoothly transmitted from the centralized power supply to the lamp body 106. This connection method is usually safe and reliable and can meet the requirements for normal operation of the lamp.

[0075] The design of centralized power supply allows multiple lamps to share one power supply device, which improves the power supply efficiency. At the same time, centralized power supply usually has excellent voltage stabilization, filtering and other functions, which can ensure that the lamps can still work stably in an environment with voltage fluctuations or large interference. By introducing centralized power supply, the need for each lamp to be configured with a separate power supply is reduced, simplifying the installation process. At the same time, during maintenance, only the centralized power supply needs to be inspected or replaced, reducing maintenance costs and workload. The design of centralized power supply usually takes into account safety protection functions such as overload and short circuit, and can cut off the power supply in time under abnormal conditions to protect the safety of lamps and surrounding equipment. In addition, centralized power supply can also be equipped with lightning protection, surge protection and other protection measures to further improve the safety of lamps.

[0076] In addition, in some other embodiments, the centralized power supply may also have an intelligent management function, and the lamps may be centrally managed through a remote monitoring or control system, which facilitates operations such as switching and dimming the lamps, and improves the convenience and flexibility of management.

[0077] A second embodiment of the present invention provides a rail vehicle, including a vehicle body and the lighting fixture as described above, wherein a substrate 100 is installed in the vehicle body.

[0078] According to the rail vehicle provided by the embodiment of the second aspect of the utility model, by arranging the above-mentioned lighting fixture in the car body, not only the lighting fixture and the internal roof structure of the car body are simplified, but also the aesthetic effect inside the car body is improved. The lamp body 106 of the lighting fixture can be selected and configured according to the specific needs of the interior of the vehicle, so as to achieve the best lighting effect. At the same time, the installation position and angle of the lamp can also be flexibly adjusted to meet the lighting needs of different areas, ensuring that passengers can get a comfortable and uniform lighting experience in the car. In addition, the detachable combination of the lighting fixture and the substrate 100 makes the installation process of the lighting fixture simpler and faster. At the same time, since the lamp body 106 can be disassembled and replaced separately, when the lamp fails, it can be quickly repaired and replaced, reducing maintenance costs and time costs.

[0079] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
