Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle interior, in particular to a vehicle roof lighting assembly. BACKGROUND

[0002] With the continuous development of the automobile and new energy automobile industry, in addition to the pursuit of driving performance and vehicle safety, people also gradually pay more attention to the driving comfort. As a factor affecting the driving comfort of the vehicle, the interior of the vehicle is becoming a key factor for consumers to purchase a vehicle. Reasonable and beautiful structure design of the vehicle interior is very important to improve the quality of the whole vehicle.

[0003] Among them, the interior light as a part of the automobile interior, its application has not only limited to provide sufficient illumination for the vehicle, people also hope to get a soothing indoor light environment in the car, the functional atmosphere lamp is the light decoration of the atmosphere created in the car, which can meet the various sensory needs of passengers in different environments. The lighting assembly arranged on the roof of the vehicle can be used as an atmosphere lamp, which can meet the lighting needs of the vehicle and create an atmosphere in the vehicle, improve the quality of the vehicle, and improve the driving comfort of the vehicle. Among them, the starry sky roof as a kind of vehicle roof lighting assembly, has the optical effect of simulating the starlight of the night sky, and is more and more favored by consumers.

[0004] At present, the starry sky roof is usually arranged on the vehicle roof. In the production of the starry sky roof, optical fiber is generally used as the light source, and an opening is needed to be arranged on the inner lining plate of the roof, that is, the top body, to expose one end of the optical fiber, and the other part of the optical fiber is fixed in the roof of the vehicle compartment. The diameter of one end of the optical fiber is exposed at the lower surface of the top body, so that the light emitted by the optical fiber is easily transmitted through the material of the lower surface of the top body, thereby producing a light spot around the opening, or producing a light spot or causing the head of the optical fiber to flicker due to the illumination of the external light source, thereby causing poor visual effect. SUMMARY

[0005] Therefore, the present application aims to provide a vehicle roof lighting assembly to improve the visual effect and improve the use quality of the vehicle.

[0006] To achieve the above-mentioned purpose, the technical scheme of the present application is as follows:

[0007] A vehicle roof lighting assembly arranged in a vehicle cabin and covering a roof held thereon, comprising: a roof body covering and held on the roof; a plurality of mounting holes formed on the roof body; a plurality of optical fibers, when each of the optical fibers is inserted and held in a corresponding one of the mounting holes from above the roof body, a fitting gap is formed between a head of each of the optical fibers and a lower surface of the roof body to constitute a hiding of the optical fiber in the mounting hole; and a hole diameter of each of the mounting holes is greater than a diameter of each of the optical fibers to form a clearance between the optical fiber and a hole wall of the mounting hole.

[0008] Further, the fitting gap is set to 0.45mm-0.55mm.

[0009] Further, the hole diameter of the mounting hole / the diameter of the optical fiber is greater than or equal to 1.5.

[0010] Further, a buffer layer is coated on an outer surface of each of the optical fibers.

[0011] Further, each of the optical fibers is classified and constrained into a bundle shape above the roof body.

[0012] Further, a support seat is fixed above the roof body, the support seat is set to a plurality corresponding to a number of the optical fibers in the bundle shape, and each of the optical fibers in the bundle shape is supported by the support seat to form a gap between each of the optical fibers and an upper surface of the roof body.

[0013] Further, each of the support seats is spaced apart.

[0014] Further, the roof body has a compression amount along a thickness direction;

[0015] When the lower surface of the roof body is pressed by an external force along the thickness direction of the roof body to increase a clearance on a side of an adjacent optical fiber, a head of the adjacent optical fiber is not lower than the lower surface of the roof body.

[0016] Further, the roof body comprises a base material layer, a non-woven fabric layer and an appearance layer stacked from top to bottom, and the appearance layer is made of imitation suede.

[0017] Compared with the prior art, the present application has the following advantages:

[0018] The vehicle roof lighting assembly of the present application hides the head of the optical fiber in the mounting hole by setting the fitting gap between the optical fiber and the roof body and the clearance between the optical fiber and the hole wall of the mounting hole, so that the light emitting point of the vehicle roof lighting assembly can better simulate the actual optical effect of starlight to improve the visual effect and thus improve the use quality of the vehicle.

[0019] The assembly gap between the head of the optical fiber and the lower surface of the top body is set to 0.45mm-0.55mm, so as to avoid the external light source from easily irradiating on the optical fiber to generate light spot or flicker, at the same time, prevent the head of the optical fiber from being too deep into the top body, which will cause the visual angle of the light emitting point to decrease, and to a certain extent, avoid the light emitted by the optical fiber from being too bright due to the too deep installation hole, so as to ensure the optical effect of the optical fiber light emitting.

[0020] The ratio of the hole diameter of the installation hole to the diameter of the optical fiber is greater than or equal to 1.5, which can avoid the hole of the lower surface of the top body being too large to be directly observed by the passengers, at the same time, avoid the ratio of the hole diameter to the diameter being too small, so that the light of the optical fiber is easily transmitted through the material of the lower surface of the top body, which generates light spot that interferes with the optical effect of the vehicle roof light emitting assembly, so as to improve the visual effect, and facilitate the installation of the optical fiber.

[0021] The outer surface of each optical fiber is covered with a buffer layer, which can form a buffer when the optical fibers collide with each other or with the top body, so as to protect the optical fibers from being damaged and affecting the optical effect. At the same time, it can also reduce the generation of abnormal sound when the collision occurs, thereby improving the comfort of the passengers.

[0022] Each optical fiber is classified and constrained into a bundle shape above the top body, so as to facilitate the fixation and bundling of each optical fiber, and reduce the collision between the optical fibers. At the same time, the optical fibers for realizing different functions can be classified and bundled together, which facilitates the installation and later maintenance of the optical fibers.

[0023] A plurality of support seats for the bundled optical fibers are fixed above the top body, and the bundled optical fibers are supported by the support seats to form a gap between the optical fibers and the upper surface of the top body. The optical fibers are prevented from colliding with the top body due to the movement and vibration of the vehicle, which to a certain extent reduces the generation of abnormal sound, and the spacing between the optical fibers and the top body provides a certain heat dissipation space for the optical fibers.

[0024] The support seats are spaced apart from each other, which provides effective support for the optical fibers, increases the heat dissipation space of the optical fibers, and reduces the number of support seats to be installed, thereby facilitating the installation of the support seats.

[0025] The top body has a compression amount along the thickness direction, and when the lower surface of the top body is pressed along the thickness direction of the top body, the adjacent optical fiber side is pulled to increase the clearance, and the head of the adjacent optical fiber is not lower than the lower surface of the top body, so as to prevent the head of the optical fiber from protruding to hurt the passenger when the passenger touches it, and improve the safety of the light emitting assembly.

[0026] The top body comprises a base material layer, a non-woven fabric layer and an appearance layer which are stacked from top to bottom to form the top body, and the appearance layer is made of imitation suede, so that the pile surface of the imitation suede makes the vehicle roof light emitting assembly have a good appearance performance, thereby improving the aesthetic degree.

[0027] In addition, another object of the present application is to provide a vehicle provided with the vehicle roof lighting assembly as described above.

[0028] The vehicle of the present application has the same beneficial effects as the vehicle roof lighting assembly compared with the prior art, which will not be described here. BRIEF DESCRIPTION OF DRAWINGS

[0042] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0043] Embodiment one

[0044] The present embodiment relates to a vehicle roof lighting assembly, which can improve the visual effect. In terms of overall structure, the vehicle roof lighting assembly of the present embodiment is arranged in the vehicle cabin and covers the roof, comprising a top body 1 and a plurality of optical fibers 3.

[0045] The top body 1 covers and is held in a plurality of mounting holes 2 on the roof, and at the same time, each optical fiber 3 is inserted from above the top body 1 and held in the corresponding mounting hole 2, and a fitting gap a is formed between the head of each optical fiber 3 and the lower surface of the top body 1, so that the optical fiber 3 is hidden in the mounting hole 2.

[0046] It can be understood that the light emitted by the optical fiber 3 is achieved by connecting the optical fiber 3 with a light source arranged on the roof of the vehicle body, so that the optical fiber 3 conducts the light emitted by the light source, and finally the light is emitted from the head of the optical fiber 3. In the process of conducting light by the optical fiber 3, most of the light is emitted through the end face of the head of the optical fiber 3. The optical fiber 3 itself is a transparent material, and the end face is usually a flat end face, so that the head of the optical fiber 3 will reflect light under external light. Especially when the vehicle cabin is relatively dark, the light emitted by other light-emitting components in the vehicle cabin or the screens of electronic devices of passengers in the vehicle cabin will be refracted into the vehicle cabin due to the head of the optical fiber 3, causing additional light spots in the vehicle cabin, destroying the light effect atmosphere created by the vehicle roof lighting assembly in the vehicle cabin, and thus causing a decrease in the visual effect.

[0047] In addition, when the head of the optical fiber 3 is flush with the lower surface of the top body 1, and in the daytime and under the condition that the vehicle roof lighting assembly is closed, the optical fiber 3 does not emit light. Because the head of the optical fiber 3 and the material of the lower surface of the top body 1 are obviously different, passengers can obviously observe the optical fiber 3 in the structure of the vehicle roof lighting assembly, and under the irradiation of external light source, the head of the optical fiber 3 made of transparent material will flicker to some extent due to the irradiation of external light source. Thus, the easily observed optical fiber 3 destroys the integrity and aesthetic degree of the vehicle roof lighting assembly.

[0048] In the embodiment, the head of the optical fiber 3 is hidden in the mounting hole 2, so that the head of the optical fiber 3 is difficult to be irradiated by the external optical fiber 3 to generate additional refraction light spot or flicker, which affects the visual effect. In addition, the head of the optical fiber 3 is hidden in the mounting hole 2, which can ensure the integrity of the lower surface of the top body 1, and can avoid the observation of the optical fiber 3 between passengers in the vehicle cabin, and improve the overall appearance of the vehicle roof lighting assembly structure.

[0049] In addition, the hole diameter b of each mounting hole 2 is greater than the diameter c of each optical fiber 3, so as to form a gap between the optical fiber 3 and the hole wall of the mounting hole 2. It can be understood that part of the light conducted by the optical fiber 3 is emitted through the outer peripheral surface of the optical fiber 3, and the lower surface of the top body 1 is usually made of a material commonly used in the interior of the vehicle cabin, such as leather, plastic parts, etc. The material cannot completely block light, and when the light is irradiated on one side of the material, the other side will produce a light spot due to incomplete transmission of light.

[0050] Therefore, when the hole diameter b of the mounting hole 2 and the diameter c of the optical fiber 3 are equal, part of the light emitted from the outer peripheral surface of the optical fiber 3 will be projected into the material constituting the lower surface of the top body 1 and transmitted through the lower surface of the top body 1, which will to some extent easily cause the generation of an annular light spot around the light emitting point of the vehicle roof lighting assembly due to the transmission of light through the material of the lower surface of the top body 1, and the brightness of the light spot gradually decreases outward from the optical fiber 3. This results in an increase in the light area at the light emitting point of the vehicle roof lighting assembly, and the boundary between the light area and the lower surface of the top body 1 is not clear, which is difficult to form a small light like starlight, resulting in a decrease in the visual effect of the lighting assembly.

[0051] In the embodiment, the gap between the optical fiber 3 and the hole wall of the mounting hole 2 is set, so that the light emitted by the optical fiber 3 is difficult to be transmitted through the material of the lower surface of the top body 1 to generate a light spot, so that the light area of the light emitting point of the lighting assembly is small, and the boundary between the light area and the lower surface of the top body 1 is clear, thereby effectively simulating the optical visual effect of starlight. At the same time, the assembly gap a between the optical fiber 3 and the lower surface, and the gap between the optical fiber 3 and the mounting hole 2, can make the end surface of the head of the optical fiber 3 and the light emitted from the outer peripheral surface of the optical fiber 3 be fully diffused in the mounting hole 2, and finally make the fully diffused light be emitted from the mounting hole 2 into the vehicle cabin, which can to some extent improve the visual angle of the light emitting point of the lighting assembly, and improve the visual effect.

[0052] In the embodiment, the diameter c of the optical fiber 3 is set to 0.5-1 mm to ensure that the optical fiber 3 has good light guiding performance and the light emitting point of the light emitting assembly can emit sufficient brightness. In addition, the optical fiber 3 is made of polymethyl methacrylate (PMMA) material, which has good light transmittance, heat resistance and rigidity, so that the optical fiber 3 is not easily damaged by external force and vibration of the vehicle in the vehicle roof, thereby reducing the service life. In addition, each optical fiber 3 is fixedly connected to the mounting hole 2 of the top body 1 by the structural adhesive 201, so as to ensure the fixation of the optical fiber 3 and maintain the assembly spacing a between the head of the optical fiber 3 and the lower surface and the clearance between the head of the optical fiber 3 and the hole wall of the mounting hole 2. In the embodiment, the structural adhesive 201 can be a conventional structural adhesive 201 known to those skilled in the art, which has good adhesive effect. In the process of bonding the optical fiber 3, the structural adhesive should be closed to the mounting hole 2 on the upper surface of the top body 1, and the structural adhesive 201 should not enter the mounting hole 2, so as to ensure the stable bonding of the optical fiber 3 and prevent the structural adhesive 201 from damaging the optical effect of the optical fiber 3.

[0053] As described above, by setting the assembly spacing a between the optical fiber 3 and the top body 1 and the clearance between the optical fiber 3 and the hole wall of the mounting hole 2, the head of the optical fiber 3 is hidden in the mounting hole 2, which avoids the generation of light spots and flicker due to the irradiation of the head of the optical fiber 3 by external light sources, so that the light emitting point of the light emitting assembly can better simulate the actual optical effect of starlight to improve the visual effect and thus improve the use quality of the vehicle.

[0054] Based on the above overall introduction, specifically, since the brightness emitted by the optical fiber 3 is limited, the assembly spacing a between the head of the optical fiber 3 and the lower surface should be set within a suitable range to ensure the optical effect of the light emitting point. In the embodiment, the assembly spacing a between the head of the optical fiber 3 and the lower surface of the top body 1 is set to 0.45-0.55 mm. When the assembly spacing a between the head of the optical fiber 3 and the lower surface of the top body 1 is too small, under a certain angle, the external light source is still easy to irradiate on the optical fiber 3 to generate light spots or flicker, or is easy to be observed by passengers in the vehicle cabin, which affects the visual effect. When the assembly spacing a between the head of the optical fiber 3 and the lower surface of the top body 1 is too large, the head of the optical fiber 3 is too deep into the top body 1, which can cause the visual angle of the light emitting point to decrease.

[0055] In addition, the light emitted by the optical fiber 3 is difficult to be emitted through the mounting hole 2 in the deep mounting hole 2, and the light intensity is reduced after excessive diffuse reflection of the light in the deep mounting hole 2, resulting in the reduction of the brightness of the light emitting point of the light emitting assembly, thereby reducing the visual effect. Therefore, by setting the assembly spacing a between the head of the optical fiber 3 and the lower surface of the top body 1 to 0.45mm-0.55mm, the additional light spot caused by the optical fiber 3 can be avoided, the light brightness of the light emitting point is ensured to be good, and the light emitting point of the light emitting assembly has a good optical effect. In specific implementation, the assembly spacing a between the head of the optical fiber 3 and the lower surface of the top body 1 can be set to 0.45mm, 0.47mm, 0.49mm, 0.51mm, 0.53mm or 0.55mm.

[0056] It can be understood that when the ratio of the hole diameter b of the mounting hole 2 to the diameter c of the optical fiber 3 is too large, the hole diameter b of the mounting hole 2 is large, the hole of the lower surface of the top body 1 is too large, and the light emitting assembly is easily observed by the passengers in the vehicle cabin, resulting in the reduction of the aesthetic degree of the light emitting assembly. In addition, when the light emitted by the optical fiber 3 is irradiated on the hole wall of the mounting hole 2, the hole wall is illuminated by the light, and the large hole diameter b is easy to make the illuminated hole wall be observed by the passengers, thereby causing the visual effect of the light emitting point to be reduced. When the ratio of the hole diameter b of the mounting hole 2 to the diameter c of the optical fiber 3 is too small, the light of the optical fiber 3 is still easy to transmit through the material of the lower surface of the top body 1, and the annular light spot is formed as described above.

[0057] Therefore, the above two cases will cause the light emitting point to be difficult to effectively simulate the effect of starlight emission, and the visual effect of the light emitting assembly is reduced. In order to ensure the effect of the optical fiber 3 of the light emitting point of the light emitting assembly, in the embodiment, the ratio of the hole diameter b of the mounting hole 2 to the diameter c of the optical fiber 3 is greater than or equal to 1.5, so that the optical fiber 3 and the mounting hole 2 have a suitable clearance, thereby improving the visual effect of the light emitting assembly. In specific implementation, the hole diameter b of the mounting hole 2 in the embodiment can be set to 1.1mm, and the diameter c of the optical fiber 3 is 0.75mm. While ensuring the optical effect, the optical fiber 3 is convenient to be arranged in the mounting hole 2.

[0058] In order to simulate the optical visual effect of the star point flickering in the night sky, a large number of light emitting points are arranged on the top body 1, that is, the mounting holes 2 and the heads of the optical fibers 3 arranged in the mounting holes 2, and the other end of each optical fiber 3 is connected with a light source, and the main body of each optical fiber 3 is held on the top body 1. In the movement of the vehicle, the main bodies of the optical fibers 3 wound on the top body 1 will collide and rub with each other, or the optical fibers 3 will collide with other structures of the top body 1 and the roof, resulting in abnormal sound at the structure of the light emitting assembly of the vehicle. At the same time, the collision between the optical fibers 3 and other structures will also cause damage to the outer surface of the optical fiber 3, thereby causing the light guiding effect of the optical fiber 3 to be reduced and the service life to be reduced.

[0059] In order to avoid abnormal sound and improve the service life of the optical fibers 3, a buffer layer is coated on the outer surface of each optical fiber 3 in the embodiment, which can buffer the collision between the optical fibers 3 or between the optical fibers 3 and other vehicle body structures, and has a soundproof effect, so that the generation of abnormal sound and damage to the optical fibers 3 can be avoided to some extent, thereby improving the service life of the optical fibers 3. In specific implementation, the buffer layer can be made of soft materials such as buffer foam and soft glue, but in order to facilitate the coating of the buffer layer and minimize the radial size of the optical fibers 3, the buffer layer is made of soft glue materials such as silica gel, TPE soft glue and TPU soft glue, which can be easily coated on the optical fibers 3, has good buffering effect and thin thickness.

[0060] In order to further avoid the collision of the optical fibers 3 and eliminate abnormal sound, each optical fiber 3 can be bundled into a bundle shape to reduce the collision between the optical fibers 3. In order to make the light emitting assembly have better visual effect, the vehicle roof light emitting assembly can be set by the cooperation of the controller and the light source to control different light sources to realize the functions of full star, meteor shower, single color, breathing, flickering and adjustable brightness. At this time, the arrangement position of the optical fibers 3 needs to be planned to facilitate the connection of different optical fibers 3 with corresponding light sources. In order to prevent the optical fibers 3 used to realize various functions from being directly mixed and arranged on the top main body 1, which affects the installation and connection of the light emitting assembly optical fibers 3 and facilitates the later maintenance and inspection.

[0061] Therefore, each optical fiber 3 in the embodiment is classified and constrained into a bundle shape above the top main body 1. After being bundled, each optical fiber 3 reduces the collision between the optical fibers 3, reduces the generation of abnormal sound to some extent, and improves the service life of the optical fibers 3. At the same time, optical fibers 3 belonging to the same type can be concentrated and bundled, and finally connected with corresponding light sources. In specific implementation, the classified and bundled optical fibers 3 should be marked with their corresponding functions to make the levels of the optical fibers 3 clear, which facilitates the installation and later maintenance of the optical fibers 3.

[0062] When the bundled optical fibers 3a are kept on the top main body 1, the vibration of the vehicle body during the movement of the vehicle can cause the bundled optical fibers 3a to vibrate and impact the top main body 1 and the roof, resulting in the generation of abnormal sound. In order to eliminate the abnormal sound to some extent, the support seats 4 are fixed above the top main body 1 in the embodiment, and the support seats 4 are set in a number corresponding to the number of the bundled optical fibers 3a. Each bundled optical fiber 3 is supported by the support seat 4 to form a gap between the optical fiber 3 and the upper surface of the top main body 1.

[0063] It can be understood that the bundle-shaped optical fiber 3a can be erected by the support seat 4, and the bundle-shaped optical fiber 3a can avoid abnormal sound caused by vehicle vibration, and affect the comfort of passengers. In specific implementation, the bundle-shaped optical fiber 3a can be fixed on the support seat 4 by a strap, and the support seat 4 can be a pad made of polyethylene terephthalate (PET) material to erect the bundle-shaped optical fiber 3a. The pad has good mechanical properties and service life, and has a light weight, which can effectively support the bundle-shaped optical fiber 3a, and facilitate installation on the top body 1. The height of the pad can be set to 20 mm to increase the spacing between the bundle-shaped optical fiber 3a and the top body 1, so as to prevent the vehicle with the roof light structure from touching the top body 1 after long-term use, causing abnormal sound.

[0064] In order to reduce the number of support seats 4 while maintaining the support of the bundle-shaped optical fiber 3a, the support seats 4 are arranged at intervals. It can be understood that installing too many support seats 4 will not only increase the cost, but also cause the installation effect of some support seats 4 to not meet the production requirements during the installation process of the support seats 4, thereby causing the support seats 4 to fall or separate during actual use of the vehicle and the light assembly, causing abnormal sound and affecting the use quality of the vehicle. In specific implementation, the support seats 4 are arranged at intervals of 200 mm to reduce the number of support seats 4, while providing a certain sag space for the bundle-shaped optical fiber 3a, and providing a certain heat dissipation space for the bundle-shaped optical fiber 3a, thereby prolonging the service life of the optical fiber 3.

[0065] In the prior art, improper operation of the passenger on the light assembly, that is, when the passenger touches the light assembly on the roof of the vehicle, the top body 1 is pressed and the head of the optical fiber 3 is exposed, thereby causing the situation that the passenger is pricked by the optical fiber 3. In order to avoid the above situation, the top body 1 of the present embodiment has a compression amount along the thickness direction, which makes the lower surface of the top body 1 soft and does not cause injury to the passenger. At the same time, when the lower surface of the top body 1 is pressed by external force along the thickness direction of the top body 1, the clearance of the adjacent optical fiber 3 on one side is increased, and the head of the adjacent optical fiber 3 is not lower than the lower surface of the top body 1. That is, when the lower surface of the top body 1 of the light assembly is pressed, the compression amount of the top body 1 is limited, and the head of the optical fiber 3 is not exposed, thereby avoiding the situation that the passenger is pricked, improving the protection of the passengers in the vehicle, and improving the use quality of the vehicle.

[0066] Specifically, the top main body 1 of the embodiment includes a substrate layer 101, a non-woven fabric layer 102 and an appearance layer 103 stacked from top to bottom, and the appearance layer 103 faces the interior of the vehicle cabin. The substrate layer 101 is the main structural component constituting the structure of the top main body 1, and the non-woven fabric layer 102 is attached and fixed on the substrate layer 101 to replace the design of the polyester sponge filling layer in the prior art, which can be used to limit the compression amount in the thickness direction of the top main body 1, and prevent the head of the optical fiber 3 from being exposed when the lower surface of the top main body 1 is pressed by touch, thereby preventing the situation of pricking the hand. At the same time, the non-woven fabric layer 102 can facilitate the fixation of the appearance layer 103 on the substrate layer 101, and facilitate the production and manufacturing of the top main body 1. In a specific implementation, the thickness of the non-woven fabric layer 102 is 0.6 mm. The mounting hole 2 on the top main body 1 is a through hole penetrating through the substrate layer 101, the non-woven fabric layer 102 and the appearance layer 103, the optical fiber 3 penetrates into the mounting hole 2 from the side of the substrate layer 101 away from the vehicle cabin, and the appearance layer 103 is attached on the non-woven fabric layer 102 by adhesive.

[0067] In order to improve the appearance of the vehicle roof lighting assembly, the appearance layer 103 of the embodiment is made of imitation suede. Specifically, the imitation suede can be made of imitation suede materials known to those skilled in the art, which has a good appearance to improve the appearance of the vehicle roof lighting assembly. In addition, since the surface of the imitation suede is usually constructed as fine and uniform fluff, the arrangement of the fluff can shield the appearance layer 103, that is, the mounting hole 2 on the top main body 1, so that the passengers in the vehicle cabin cannot easily observe the existence of the mounting hole 2 in the off state of the vehicle roof lighting assembly, and the optical effect of simulated starlight of the night sky can be quickly highlighted in the on state of the vehicle roof lighting assembly. The starry night effect can bring better visual shock to the passengers, thereby improving the visual effect of the vehicle roof lighting assembly and the use quality of the vehicle.

[0068] In summary, the vehicle roof lighting assembly of the embodiment hides the head of the optical fiber 3 in the mounting hole 2 by setting the assembly spacing a between the optical fiber 3 and the top main body 1 and the clearance between the optical fiber 3 and the hole wall of the mounting hole 2, which avoids the generation of light spots and flicker due to the irradiation of the head of the optical fiber 3 by external light sources, and further makes the light emitting point better simulate the actual optical effect of starlight, thereby improving the visual effect of the vehicle roof lighting assembly and the use quality of the vehicle.

[0069] Embodiment Two

[0070] The embodiment relates to a vehicle, and the vehicle is provided with the vehicle roof lighting assembly as described in Embodiment One.

[0071] As described above, the vehicle of the present embodiment can produce a visual effect of simulated starlight on the ceiling in the vehicle cabin through the vehicle ceiling light emitting assembly, so as to create an atmosphere in the vehicle and improve the driving comfort of the vehicle, thereby improving the use quality of the vehicle.
