[0024] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the present application, rather than all of the embodiments.

[0026] like Figures 1 to 3 As shown, an embodiment of the present application provides a cabin lighting device, including a ceiling 1 and a lighting lamp, wherein the lighting lamp is arranged on at least one side of the ceiling 1, and the light emitted by the lighting lamp is directed toward the ceiling 1. The light emitted by the lighting lamp irradiates the ceiling 1, converting the ceiling 1 into a light-emitting surface, and provides lighting in the cabin after being reflected by the ceiling 1. The cabin lighting device provided by the present application uses indirect lighting to illuminate the cabin, and the light is softer. Passengers will not look directly at the light, thus avoiding the problem of glare.

[0027] Furthermore, in some embodiments of the present application, a mounting groove 301 is provided at the edge of the ceiling 1, and the lighting lamp is arranged in the mounting groove 301. The lighting lamp is arranged in the mounting groove 301 to hide the lighting lamp. On the one hand, it can prevent the light emitted by the lighting lamp from directly irradiating into the cabin and avoid the risk of glare caused by passengers looking directly at the lighting lamp. On the other hand, hiding the lighting lamp through the mounting groove 301 gives the cabin a high-end feeling of seeing light but not lamps, thereby improving the aesthetics of the cabin.

[0028] Furthermore, in some embodiments of the present application, the mounting groove 301 can be formed by the ceiling 1 structure. For example, the edge of the ceiling 1 is bent downward and inward to form the mounting groove 301, and the lighting lamp is set in the mounting groove 301 for hiding; or the mounting groove 301 is formed on the edge of the ceiling 1 by a specific fixing member 3 to install and hide the lighting lamp. The fixing member 3 is connected between the ceiling 1 and the measuring shelf of the cockpit, and the fixing member 3 has a mounting groove 301, and the notch of the mounting groove 301 faces away from the side ceiling 1 frame.

[0029] Specifically, in some embodiments of the present application, the cross-section of the fixing member 3 is in the shape of a U-shape rotated 90°. The fixing member 3 is arranged at the left edge and / or the right edge of the ceiling 1 and extends along the front-rear direction of the ceiling 1. When the fixing member 3 is arranged at the left edge of the ceiling 1, the notch of the mounting groove 301 formed on the fixing member 3 is arranged to the right, and when the fixing member 3 is arranged at the right edge of the ceiling 1, the notch of the mounting groove 301 formed on the fixing member 3 is arranged to the left. The light emitted by the lighting lamp is emitted through the notch of the mounting groove 301, hits the ceiling 1, and is reflected by the ceiling 1 to illuminate the cabin.

[0030] Further, such as Figure 3 As shown, in some embodiments of the present application, the fixing member 3 includes a first connecting plate 31, a second connecting plate 32 and a third connecting plate 33. The first connecting plate 31 is connected between the ceiling 1 and the side ceiling 1 frame along the width direction of the ceiling 1. The second connecting plate 32 is located below the first connecting plate 31 and is arranged opposite to the first connecting plate 31. The third connecting plate 33 is connected between the first connecting plate 31 and the second connecting plate 32, and the third connecting plate 33 forms the bottom of the installation groove 301. The first connecting plate 31 and the second connecting plate 32 form two side walls of the installation groove 301.

[0031] The first connecting plate 31, the second connecting plate 32 and the third connecting plate 33 jointly surround a mounting groove 301, and the lighting lamp is installed in the mounting groove 301 surrounded by the first connecting plate 31, the second connecting plate 32 and the third connecting plate 33, and the light emitted by the lighting lamp is emitted through the notch of the mounting groove 301 and is incident on the ceiling 1, and is reflected by the ceiling 1 to illuminate the cabin.

[0032] Furthermore, the lighting lamp includes a lamp board 41 and a diffuser plate 43. The lamp board 41 can be set on any one of the first connecting plate 31, the second connecting plate 32 and the third connecting plate 33. The upper end of the diffuser plate 43 is connected to the first connecting plate 31, and the lower end of the diffuser plate 43 is connected to the second connecting plate 32. The lamp board 41 is set in a cavity surrounded by the diffuser plate 43, the first connecting plate 31, the second connecting plate 32 and the third connecting plate 33. The light emitted by the lamp board 41 is more divergent after being diffused by the diffuser plate 43.

[0033] The first connecting plate 31 and the second connecting plate 32 are respectively provided with snap-fitting grooves. The upper end of the diffuser plate 43 is snap-fitted with the snap-fitting groove on the first connecting plate 31 , and the lower end of the diffuser plate 43 is snap-fitted with the snap-fitting groove on the second connecting plate 32 .

[0034] For example, in some embodiments of the present application, the light board 41 is disposed on the third connecting plate 33 and is located on a side surface of the third connecting plate 33 away from the side ceiling frame 2. The light emitted by the light board 41 is directed toward the notch of the mounting slot 301. The diffuser plate 43 is located between the notch and the light board 41. The light emitted by the light board 41 is diffused by the diffuser plate 43, and the light is more divergent and softer. The light passing through the diffuser plate 43 partially hits the ceiling 1, thereby realizing the lighting of the cabin. The diffuser plate 43 can be arranged in a vertical direction or tilted. In some embodiments, it is preferred that the upper end of the diffuser plate 43 is tilted toward the direction close to the third connecting plate 33. The light after passing through the diffuser plate 43 has a tendency to be emitted upward, so that more light can hit the ceiling 1, and is reflected by the ceiling 1 to illuminate the cabin.

[0035] For example, in some embodiments of the present application, the light board 41 can also be set on the second connecting plate 32, the light board 41 is fixedly connected to the second connecting plate 32, the lamp beads on the light board 41 face the first connecting plate 31, and a reflector is set at the connection between the first connecting plate 31 and the third connecting plate 33. The light emitted by the light board 41 is irradiated onto the reflector, and after being reflected by the reflector, the reflected light is directed toward the notch of the mounting groove 301. The diffuser plate 43 is connected between the first connecting plate 31 and the second connecting plate 32. The light emitted from the notch of the mounting groove 301 must be diffused by the diffuser plate 43. The diffused light is more dispersed and softer, avoiding dazzling. By setting the inclination angle of the diffuser plate 43, the angle of the light emitted from the notch of the mounting groove 301 can be adjusted, thereby controlling the light to hit the ceiling 1, and after being reflected by the ceiling 1, the cabin is illuminated.

[0036] For example, in some embodiments of the present application, the light board 41 can also be arranged on the first connecting plate 31, and the light board 41 is fixedly connected to the first connecting plate 31, and the lamp beads on the light board 41 face the second connecting plate 32. By adjusting the angle of the light board 41 or setting a reflection device between the second connecting plate 32 and the third connecting plate 33, the light emitted by the light board 41 or the light reflected by the reflection device is directed toward the notch of the installation groove 301. The diffusion plate 43 is connected between the first connecting plate 31 and the second connecting plate 32. The light emitted from the notch of the installation groove 301 must be diffused by the diffusion plate 43. The diffused light is more dispersed and softer, avoiding dazzling. By setting the inclination angle of the diffusion plate 43, the angle of the light emitted from the notch of the installation groove 301 can be adjusted, and then the light can be controlled to hit the ceiling 1, and the light can be reflected by the ceiling 1 to illuminate the cabin.

[0037] Specifically, the lamp board 41 and the fixing member 3 are fixed by adhesive tape or screws.

[0038] That is to say, the function of the mounting groove 301 is to hide and install the lighting lamp. The light board 41 can be installed at any position of the mounting groove 301. By adjusting the installation angle of the light board 41 and setting the reflecting device, it is ensured that the light emitted by the light board 41 is finally emitted from the notch of the mounting groove 301, and as much light as possible hits the ceiling 1. After being reflected by the ceiling 1, the cockpit is illuminated to form an indirect lighting effect.

[0039] In some embodiments of the present application, the diffuser plate 43 adopts a lamp mask, specifically, a milky white mask.

[0040] Furthermore, in some embodiments of the present application, the reflective device may be a reflective bowl 42, which is a parabolic curved surface design that can more effectively reduce light loss. The light emitting angle of the reflective bowl 42 light source and the spatial structure of the reflective bowl 42 can be simulated by computer modeling to track the reflection trajectory of the light. Therefore, the size and installation angle of the reflective bowl 42 can be designed according to optical requirements.

[0041] The lamp board 41 includes a PCB board and LED chips and lamp beads arranged on the PCB board. A plurality of LED chips are evenly distributed on the PCB board, and the outside of each LED chip is wrapped with a hemispherical lamp bead.

[0042] Furthermore, in some embodiments of the present application, one end of the first connecting plate 31 connected to the ceiling 1 is provided with a snap buckle, which is snap-fitted and fixed to the edge of the ceiling 1; the end of the first connecting plate 31 away from the ceiling 1 abuts against the side ceiling frame 2 and is fixedly connected to the side ceiling frame 2, one end of the second connecting plate 32 abuts against the side ceiling frame 2, and there is a certain gap between the third connecting plate 33 and the side ceiling frame 2, and the third connecting plate 33 and the side ceiling frame 2 are fixedly connected by fasteners 5. In some embodiments of the present application, the fasteners 5 between the third connecting plate 33 and the side ceiling frame 2 are bolts.

[0043] Specifically, a snap-fit ​​buckle is provided with a snap-fit ​​groove, and the edge of the ceiling 1 is inserted into the snap-fit ​​groove. In some preferred embodiments, the side of the ceiling 1 exposed in the cabin is flush or smoothly connected with the exposed part of the snap-fit ​​buckle to avoid affecting the overall aesthetics of the cabin.

[0044] Further, in some embodiments of the present application, the first connecting plate 31, the second connecting plate 32 and the third connecting plate 33 are all shading plates to prevent the light emitted by the lighting lamp from being emitted through the first connecting plate 31, the second connecting plate 32 or the third connecting plate 33. Specifically, the first connecting plate 31, the second connecting plate 32 and the third connecting plate 33 can be made of the same material as the ceiling 1, or a different material from the ceiling 1.

[0045] Further, such as Figure 1As shown, in some embodiments of the present application, the lighting lamps can be continuously arranged along at least one side of the ceiling 1. That is, the lighting lamps are long strips and are arranged on the left and right sides of the ceiling 1 along the front-to-back direction of the ceiling 1. The length of the lighting lamps is equal to or slightly less than the length of the ceiling 1 along the front-to-back direction, so that the entire cabin can be illuminated. Alternatively, lighting lamps are respectively arranged on the front side, right side, left side and right side of the cabin, and the lighting lamps surround the ceiling, and the lighting lamps on each side of the cabin are long strips of lamp tubes.

[0046] Or, if Figure 2 As shown, multiple lighting lamps can also be arranged on any side of the ceiling 1. The multiple lighting lamps are arranged at intervals along one side of the ceiling 1. Baffles are arranged between adjacent lighting lamps to separate adjacent lighting lamps to prevent mutual influence between adjacent lighting lamps. In order to install lighting lamps, the fixing member 3 can also be arranged in sections to form multiple installation grooves 301, and one or more lighting lamps can be installed in each installation groove 301.

[0047] Furthermore, some embodiments of the present application provide a vehicle, comprising the cabin lighting device in any of the above embodiments.

[0048] In summary, the cabin lighting device provided in the embodiment of the present application installs and hides the lighting lamp by providing a mounting groove 301 at the edge of the ceiling 1, thereby avoiding the risk of light emitted by the lighting lamp directly irradiating into the cabin and causing dazzle to passengers. At the same time, the use of the mounting groove 301 to hide the lighting lamp also gives the cabin a high-end feel where light can be seen but the lamp is not visible, thereby improving the aesthetics of the cabin.
