Technical Field

[0001] This utility model relates to the field of lighting equipment technology, and in particular to a large-area ring lamp for the driver's cab of a rail passenger car. Background Technology

[0002] The driver's cab is the core control center of the railcar, where operators issue commands to control the entire operation of the railcar. At night, operators rely on lights installed on the ceiling of the driver's cab for illumination. However, traditional luminous panels mostly rely solely on light-emitting modules for illumination, resulting in poor lighting effects. Therefore, at night, operators cannot quickly see the lights, which can affect their operation and pose a safety hazard.

[0003] The prior art CN222713458U discloses a light-emitting panel for a high-speed train driver's cab, including a panel body. A flexible light strip and a control button are respectively arranged on the left side of the panel body. The control button has an internal mounting cavity, and a light-emitting mechanism is arranged inside the mounting cavity. A rear cover is provided on the rear surface of the control button. By using the structural design of the light-emitting mechanism, the light emitted by the light-emitting diode is fully distributed on the rear cover with the cooperation of the reflector and the light guide plate, thereby improving the light-emitting effect of the control button, making it easier for the operator to quickly see the button on the panel, and eliminating safety hazards.

[0004] Regarding the aforementioned luminous panels in the driver's cab of high-speed trains, since the lighting conditions in the driver's cab have a direct impact on the driver's operation, and the existing lamps have uneven light and insufficient coverage, it is difficult to meet the requirements for large-area uniform lighting in the driver's cab.

Detailed Implementation

[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0019] The embodiment of this application is as follows:

[0020] Please see Figures 1-4 , Figure 1 This is a schematic diagram of the overall structure of the large-area ring light fixture for the driver's cab of a rail passenger car, which is based on this utility model. Figure 2 This is a schematic diagram of the structure of the annular diffuser plate 104 of this utility model. Figure 3 This is a structural schematic diagram of the back cover 101, heat dissipation holes 110, and back protrusion 111 of this utility model. Figure 4 This is a schematic diagram of the power supply unit of this utility model.

[0021] This utility model relates to a large-area ring-shaped light fixture for a railway passenger car driver's cab, comprising a rear cover 101, a front panel 102, a frame 103, a ring-shaped diffuser plate 104, a power module 105, an input power supply interface 106, a light source power supply interface 107, a fixing lug 108, a mounting threaded sleeve 109, heat dissipation holes 110, and a rear protrusion 111. It solves the problem that existing lighting fixtures suffer from uneven light distribution and insufficient coverage, failing to meet the requirements for large-area uniform lighting in the driver's cab, as the lighting conditions in the driver's cab directly affect the driver's operation. It is understood that the aforementioned solution can also be used to improve lighting effects.

[0022] In this embodiment, the rear cover 101 is a prior art technology. The lamp assembly is installed on the rear cover 101, thereby solving the problem that the lighting conditions in the driver's cab have a direct impact on the driver's operation, and the existing lamps have uneven light and insufficient coverage, making it difficult to meet the requirements of large-area uniform lighting in the driver's cab.

[0023] The front panel 102 is fixedly connected to the rear cover 101 and located on one side of the rear cover 101. The frame 103 is fixedly connected to the rear cover 101 and located on the side of the rear cover 101 closest to the front panel 102. The annular diffuser plate 104 is installed between the front panel 102 and the annular diffuser plate 104. The power supply unit is installed on the rear cover 101 and located on the side of the rear cover 101 furthest from the front panel 102. The mounting component is disposed on the frame 103. The front panel 102 is a rectangular plate and is fixedly connected to the rear cover 101. A light-emitting component is disposed inside the rear cover 101 as a light source. The frame 103 is a hollow rectangular frame and is fixedly connected to the rear cover 101. The annular diffuser plate 104 is annular, made of polycarbonate (PC), and has a density of 85%-90%. With a light transmittance close to that of glass, and through the addition of special additives (such as microparticles and diffusing agents) or surface treatments (such as frosting and texture processing), a translucent "light-diffusing PC" can be formed. This material does not directly transmit strong light like transparent glass, but allows light to undergo multiple refractions, reflections, and scattering as it passes through the material, breaking up concentrated beams and eliminating local over-brightness or shadows. It is suitable for scenarios requiring high uniform illumination, such as the driver's cab. The power supply unit is located on the outside of the rear cover 101 and is responsible for converting 110V voltage into low-voltage DC power required by the LED light source and providing a stable current output. The mounting components facilitate the overall installation of the lamp on the ceiling of the driver's cab. Through the design of the annular diffuser plate 104 in conjunction with the frame 103, a larger lighting area can be covered. Compared with traditional single-point or small-area light sources, it reduces lighting dead zones and increases the coverage area, thereby solving the problem that the lighting conditions in the driver's cab have a direct impact on the driver's operation, and that the existing lamps have uneven light and insufficient coverage, making it difficult to meet the requirements of large-area uniform illumination in the driver's cab.

[0024] Secondly, the power module 105 is fixedly connected to the rear cover 101 and is located on the side of the rear cover 101 away from the front panel 102; the input power supply interface 106 is located on one side of the power module 105; the light source power supply interface 107 is located on the side of the power module 105 away from the input power supply interface 106. The power module 105 includes an input protection unit, a rectification and filtering unit, a power conversion unit, a control feedback unit, and an output processing unit. The input power supply interface 106 is used to connect to an external DC 110V power supply. The light source power supply interface 107 is connected to the internal LED light source board. By controlling the function level switching, different voltages are output to drive the LED to emit light. Through the power supply unit, the 110V voltage is converted into the low-voltage DC power required by the LED light source and a stable current output is provided.

[0025] Meanwhile, the fixing lug 108 is fixedly connected to the frame 103 and located on the side of the frame 103 near the rear cover 101; the mounting threaded sleeve 109 is fixedly connected to the frame 103 and located on the side of the frame 103 near the fixing lug 108. The fixing lug 108 is Z-shaped, and there are multiple of them, all arranged around the frame 103 and extending outward. The fixing lug 108 has through holes to facilitate the passage of screws. There are multiple mounting threaded sleeves 109, which are evenly arranged around the frame 103. The mounting threaded sleeve 109 has internal threads for fixing the decorative panel. After the fixing lug 108 is fixed to the top plate of the driver's cab with screws, the entire lamp can be stably installed on the top of the driver's cab. Then, the decorative panel is installed, and the screws are locked into the mounting threaded sleeve 109 to fix the decorative panel and the entire lamp. Through the mounting components, it is convenient to install and fix the lamp to the top plate of the driver's cab.

[0026] In addition, the heat dissipation hole 110 is provided on the rear cover 101 and is located on the side of the rear cover 101 away from the front panel 102. The heat dissipation hole 110 is opened on the back side of the rear cover 101, which can promote air circulation. Through the heat dissipation hole 110, the lamp can be better dissipated.

[0027] Finally, the back protrusion 111 is fixedly connected to the back cover 101 and is located on the side of the back cover 101 near the heat dissipation hole 110. The back protrusion 111 is located on the back side of the back cover 101 and protrudes from the back cover 101. Through the back protrusion 111, the back cover 101 can be prevented from being in close contact with the object, and the heat dissipation hole 110 can be prevented from being blocked and affecting heat dissipation.

[0028] In this embodiment, the lamp is installed on the ceiling of the driver's cab. After the power line is connected, the lamp is fixed to the fixing lug 108 with screws. After the lamp is installed, a decorative panel is installed to cover the fixing lug 108 to improve aesthetics. When installing the decorative panel, the decorative panel is fixed by passing screws through the decorative panel and locking them into the mounting threaded sleeve 109. After installation, a control knob switch is installed at a designated position in the driver's cab to control the switching on and off of the lamp and the brightness of the light. When the lamp is turned on, because the annular diffuser plate 104 is arranged in a ring, the light emitted by the LED light source is refracted and scattered multiple times by the annular diffuser plate 104, forming a soft and uniform annular light curtain. The light spreads naturally from the top edge of the driver's cab towards the central area, illuminating the dashboard and control buttons in the driving operation area, as well as covering the side equipment and corner spaces. This eliminates the shadow areas that are prone to occur with traditional lamps, allowing the driver to obtain clear, glare-free lighting from any angle. It precisely meets the large-area, blind-spot-free lighting needs of the driver's cab, ensuring visual comfort and clear observation during driving operations. It solves the problem that existing lamps have uneven light and insufficient coverage, making it difficult to meet the requirements of large-area, uniform lighting for the driver's cab, since the lighting conditions in the driver's cab have a direct impact on the driver's operation.

[0029] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
