Description

Technical Field

[0001] This utility model relates to the field of lighting device technology, specifically an energy-saving lighting device for rail transit. Background Technology

[0002] The construction of rail transit has brought great convenience to the lives of urban residents and alleviated urban traffic congestion. In the underground space of rail transit, lighting fixtures are mostly standard fixtures produced by mechanized mass production. The fixtures are relatively simple and cannot be well adapted to the auxiliary structures of subway stations.

[0003] According to a public notice (Announcement No.: CN217153980U) regarding a lighting fixture and device for space lighting in rail transit, the aforementioned application relates to the field of lighting devices, and its technical solution is as follows: it includes a lighting fixture housing with a wavy curved surface on the side wall, and the wavy curved surface is provided with an array of through holes; an LED lighting module is installed inside the lighting fixture housing.

[0004] However, in actual use, the light emitted by the LED beads is reflected multiple times inside the lamp, and only a portion of the light energy is emitted through the through hole, resulting in a decrease in overall light output efficiency. At the same time, due to the complex light output path, bright spots or dark areas may be formed in some corners, affecting visual comfort. In view of this, we propose an energy-saving lighting device for rail transit. Utility Model Content

[0005] The purpose of this invention is to provide an energy-saving lighting device for rail transit, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an energy-saving lighting device for rail transit, comprising a support rod, a lampshade fixedly connected to the top end face of the support rod, an LED bead fixedly connected to the inner bottom surface of the lampshade, and a reflective component provided on the outer wall of the lampshade, the reflective component comprising:

[0007] Light-transmitting opening one is provided on the top end face of the lampshade, and light-transmitting opening two is provided on the top end face of the lampshade;

[0008] Bolt 1, which is threadedly connected to reflector plate 1;

[0009] Bolt 2 is threadedly connected to the hinge rod, the hinge rod is sleeved with bolt 3, and bolt 3 is threadedly connected to reflector plate 2.

[0010] Preferably, a transparent glass plate is fixedly connected to the inner wall of the first light-transmitting opening and the second light-transmitting opening, and two sets of the first light-transmitting openings are provided, with the two sets of the first light-transmitting openings symmetrically arranged on both sides of the second light-transmitting opening.

[0011] Preferably, there are two sets of reflector plate one, reflector plate two, and hinge rod, and the two sets of reflector plate one, reflector plate two, and hinge rod are symmetrically arranged on both sides of the light-transmitting opening two.

[0012] Preferably, bolt one is sleeved with the outer wall of the lampshade, bolt two is sleeved with the outer wall of the lampshade, and rotating bolt one and bolt two tightens the angle of reflector one and hinge rod.

[0013] Preferably, bolts two and three are symmetrically arranged at both ends of the hinge rod, and bolt three is located in the middle of reflector two. By adjusting the position of reflector two, the angle of light illumination can be changed.

[0014] Preferably, a transparent frosted plate is hinged to the top end face of the lampshade, and the transparent frosted plate is movably connected to the light-transmitting opening.

[0015] Preferably, a bracket is fixedly connected to the side wall of the lampshade, and the top of the bracket is movably connected to a transparent frosted plate.

[0016] Compared with the prior art, this utility model provides an energy-saving lighting device for rail transit, which has the following beneficial effects:

[0017] 1. This energy-saving lighting device for rail transit uses reflective components. Part of the light shines through the light-transmitting port two onto the ceiling of the building. The ceiling, as a large diffuse reflector, reflects the light, achieving large-area, uniform diffused lighting and enhancing the sense of brightness and visual hierarchy in the space. The other part of the components shines on the ground. By adjusting the angle and position of the reflector two, the angle of light illumination can be changed, making the same luminaire suitable for different platform structures, installation heights, and widths. This improves versatility and on-site adaptability. It can also actively shut off one side of the light path and enhance the lighting on the other side as needed, creating stronger illuminance in designated areas for focused lighting.

[0018] 2. This energy-saving lighting device for rail transit uses a transparent frosted plate to disperse the straight light emitted through the light-transmitting port into uniform diffused light, avoiding the formation of concentrated light spots on the ceiling, making the ceiling light spots softer and more uniform, creating comfortable ambient light, and improving the quality of indirect lighting.

[0024] like Figures 1-4 As shown, this utility model provides a technical solution: an energy-saving lighting device for rail transit, including a support rod 1, a lamp cover 2 fixedly connected to the top end face of the support rod 1, an LED bead 3 fixedly connected to the inner bottom face of the lamp cover 2, and a reflective component 4 provided on the outer wall of the lamp cover 2. The reflective component 4 includes a light-transmitting opening 401, a light-transmitting opening 402, a bolt 403, a reflector 404, a bolt 405, a hinge rod 406, a bolt 407, and a reflector 408.

[0025] In one embodiment of this utility model, a light-transmitting opening 401 is provided on the top end face of the lampshade 2, and the light-transmitting opening 401 is set at 45° with the horizontal plane. A light-transmitting opening 402 is provided on the top end face of the lampshade 2. A transparent glass plate is fixedly connected to the inner wall of the light-transmitting opening 401 and the light-transmitting opening 402. There are two sets of light-transmitting openings 401, and the two sets of light-transmitting openings 401 are symmetrically arranged on both sides of the light-transmitting opening 402.

[0026] Bolt 403 is threadedly connected to reflector 404, which is set at a 45° angle to the horizontal plane. Bolt 405 is threadedly connected to hinge rod 406. Bolt 403 and bolt 405 are fitted onto the outer wall of lampshade 2. Rotating bolts 403 and 405 tightens the angle of reflector 404 and hinge rod 406. Hinge rod 406 is fitted onto bolt 407, which is connected to the reflector. The second 408 threaded connection, the second 405 and the third 407 are symmetrically arranged at both ends of the hinge rod 406, and the third 407 is located in the middle of the second reflector 408. By adjusting the position of the second reflector 408, the angle of light illumination can be changed. There are two sets of the first reflector 404, the second reflector 408 and the hinge rod 406. The two sets of the first reflector 404, the second reflector 408 and the hinge rod 406 are symmetrically arranged on both sides of the second light-transmitting opening 402.

[0027] This device can be directly installed inside using the support rod 1, or the lampshade 2 and reflector 4 can be installed on the ceiling or wall of the building using the bracket 6.

[0028] When LED bead 3 is powered on, a portion of the light shines through the light-transmitting port 401 onto reflector 404. The light is then refracted onto reflector 408 and reflected downwards to the ground, illuminating the rail transit platform. Rotating bolts 405 and 407 loosens and adjusts the hinge rod 406 and reflector 408, allowing adjustment of the angle and position of reflector 408 to change the angle of light illumination. Tightening bolts 405 and 407 fixes the angle of reflector 408 and hinge rod 406. Increasing the reflection angle illuminates distant areas, while decreasing the reflection angle enhances near-field lighting. This allows the same luminaire to be used with different platform structures, installation heights, and widths, improving versatility and on-site adaptability. Multi-level reflection control helps to smoothly diffuse the concentrated light source. By adjusting the position of reflector 408, lighting dead zones can be filled, or excessive lighting in a certain area can be weakened, improving visual comfort.

[0029] Rotate bolt 403 to block the light-transmitting opening 401 on one side of the reflector 404. The reflector 404 can then reflect the light onto another set of reflectors 408. The light path on one side can be actively closed as needed on site to enhance the lighting on the other side, creating stronger illuminance in the designated area for focused lighting. One set of luminaires can meet the needs of different installation positions or lighting directions, enhancing the flexibility of light distribution.

[0030] Another portion of the light shines on the building’s ceiling through light-transmitting port 2402. The ceiling, as a large diffuse reflector, reflects the light, achieving large-area, uniform diffused lighting. This can eliminate shadows and light spots, improve the oppressive and dim feeling commonly found in underground or enclosed spaces, and enhance the brightness and visual hierarchy of the space.

[0031] In addition, a transparent frosted plate 5 is hinged to the top end face of the lampshade 2. The transparent frosted plate 5 is movably connected to the second light-transmitting opening 402. A bracket 6 is fixedly connected to the side wall of the lampshade 2. The top of the bracket 6 is movably connected to the transparent frosted plate 5. By rotating the transparent frosted plate 5 above the second light-transmitting opening 402, the transparent frosted plate 5 itself has the function of diffusing light, breaking the straight light emitted through the second light-transmitting opening 402 into uniform diffused light, avoiding the formation of concentrated light spots on the ceiling, making the ceiling light spots softer and more uniform, creating comfortable ambient light, and improving the quality of indirect lighting.

[0032] In this invention, when the LED bead 3 is powered on, a portion of the light shines through the light-transmitting opening 401 onto the reflector 404, and then the light is refracted onto the reflector 408 and reflected downwards to the ground to illuminate the rail transit platform. Another portion of the light shines through the light-transmitting opening 402 onto the ceiling of the building. The ceiling, as a large diffuse reflector, reflects the light, achieving large-area, uniform diffused lighting, enhancing the brightness and visual hierarchy of the space. Adjusting the angle and position of the reflector 408 changes the angle of light illumination. If the reflector 404 blocks one side of the light-transmitting opening 401, it can reflect the light onto another set of reflectors 408. The light path on one side can be actively closed as needed to enhance the lighting on the other side, creating stronger illuminance in a designated area for focused lighting.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
