[0046] The means of transportation provided in the embodiments of the present application may be an airplane, a car, a train, etc. The following embodiments are described using a car as an example.

[0047] The lighting device provided in the embodiment of the present application can be installed on the roof of a car to illuminate the driving space, and can also be installed on the interior of the trunk to illuminate the trunk space. The specific location where the lighting device 100 is installed in the interior of the car is not limited.

[0048] Please refer to Figures 1 to 5 The embodiment of the present application provides a lighting device, wherein the lighting device 100 includes a bracket 10, a lamp body 20 and a rotating shaft 30. The bracket 10 may be a car roof or a part of a car roof, or may be connected to the car roof by fasteners.

[0049] The lamp body 20 can be rotatably connected to the bracket 10. The lamp body 20 includes a lamp housing 210, a first light source 220 and a second light source 230. The light spot area formed by the first light source 220 is different from the light spot area formed by the second light source 230 to meet the lighting needs of the driver and passengers.

[0050] The first light source 220 and the second light source 230 are respectively connected to the uniform light circuit board 221 and the focusing light circuit board 231. The uniform light circuit board 221 and the focusing light circuit board 231 are respectively connected to different positions of the lamp housing 210. The uniform light circuit board 221 and the focusing light circuit board 231 can be connected to the lamp housing 210 by welding, but of course it is not limited to this.

[0051] For example, the first light source 220 is configured to emit a uniformly distributed light beam. This uniform beam ensures even light distribution without noticeable brightness variations, making it suitable for illuminating large areas and reducing glare and harshness. The second light source 230 is configured to emit a focused light beam. This focused beam concentrates its energy on a specific area, significantly enhancing the long-range illumination capability in dark environments and facilitating finding objects in corners or confined spaces.

[0052] The shaft 30 passes through the lamp body 20 and the bracket 10, and the lamp body 20 can rotate around the shaft 30. When the lamp body 20 rotates around the shaft 30, the illumination angle of the first light source 220 and / or the second light source 230 can be selectively adjusted.

[0053] In the above lighting device 100 , the lamp body 20 can rotate around the rotating shaft 30 , and the illumination angle of the first light source 220 and / or the second light source 230 can be adjusted to meet the lighting needs of the driver and passengers and improve the driving experience of the driver and passengers.

[0054] It should be noted that the first light source 220 and the second light source 230 can realize simultaneous lighting or simultaneous lighting off according to the circuit design, or can realize separate lighting or separate lighting off. They can be set according to needs and are not specifically limited in the embodiments of the present application.

[0055] Optionally, the rotating shaft 30 may be a pin passing through the lamp body 20 and the bracket 10 , or a roller passing through the lamp body 20 and the bracket 10 , with both ends of the roller connected to the interior of the car. Figure 1 The rotating shaft member 30 shown in FIG. 1 is a roller.

[0056] Figure 1 The diagram shows the state of the lamp body 20 in three different positions. The lamp body 20 is in the first position. Figure 1 The arrow m1 shown in FIG. 1 indicates the state of the lamp body 20. When the lamp body 20 is in the first position, the lamp body 20 is in the normal lighting mode, that is, only the first light source 220 is lighting. Figure 2 The position state between the lamp body 20 and the bracket 10 is shown in the figure. The lamp body 20 is embedded in the bracket 10, and the surface of the lamp body 20 is parallel to the surface of the bracket 10 or the surface of the lamp body 20 and the surface of the bracket 10 are located on the same plane to improve the integrity and aesthetics of the car interior.

[0057] External force acts on one end of the lamp body 20, so that the lamp body 20 rotates around the rotating shaft 30, and the illumination angle of the first light source 220 and / or the second light source 230 can be selected. The driver pushes the left end of the lamp body 20 toward the interior of the car, and the lamp body 20 rotates clockwise around the rotating shaft 30, that is, Figure 1 The lamp body 20 can be rotated to the second position by rotating in the direction of the arrow r1 shown in FIG. Figure 1 The position pointed by the arrow m2 shown in FIG. 1 is the same as the third position, i.e. Figure 1 The arrow m3 shown in FIG.

[0058] Figure 1 Schematic diagrams of the lamp body 20 at only the first, second and third positions are shown. The lamp body 20 can be rotated to more positions to meet the needs of drivers and passengers.

[0059] In an optional embodiment, the bracket 10 includes a ceiling frame 110 and a shaft mounting frame 120 . The shaft mounting frame 120 is connected to the ceiling frame 110 . The shaft mounting frame 120 has a first mounting hole 121 . The shaft member 30 is inserted into the first mounting hole 121 .

[0060] As an example, the shaft mounting frame 120 is integrally formed with the ceiling frame 110 to improve the structural strength of the bracket 10. Of course, the shaft mounting frame 120 can also be connected to the ceiling frame 110 by fasteners, which is not limited in the embodiment of the present application.

[0061] Furthermore, if Figure 1 and Figure 3 As shown, the ceiling frame 110 is provided with a first through slot 111, and the lamp body 20 matches the first through slot 111 and can rotate within the first through slot 111. The matching of the lamp body 20 with the first through slot 111 can improve the overall consistency of the lamp body 20 and the ceiling frame 110, thereby enhancing the aesthetics of the vehicle interior.

[0062] In an optional embodiment, the distance between the hole wall of the first mounting hole 121 and the outer wall of the rotating shaft 30 ranges from 0.03 mm to 0.07 mm. This distance range enables the pillow lamp body 20 to rotate flexibly around the rotating shaft 30, and also enables the lamp body 20 to have a certain damping feeling during the rotation process, so that the lamp body 20 can maintain a stable state after the angle is adjusted.

[0063] In an optional embodiment, the lamp body 20 also includes a lampshade 240, which is covered on the lamp housing 210, and the first light source 220 and the second light source 230 are housed in the lampshade 240. The lampshade 240 has a second mounting hole 241, and the second mounting hole 241 corresponds to the position of the first mounting hole 121. The rotating shaft 30 is inserted into the second mounting hole 241 and the first mounting hole 121.

[0064] The lampshade 240 can be connected to the lamp housing 210 by snapping, but is not limited thereto. The lamp body 20 also includes a reflector bowl 232, which is welded to the focusing light circuit board 231. The second light source 230 forms a focused light beam through the reflector bowl 232 to increase the light intensity of the light beam, thereby improving the long-range lighting capability.

[0065] Please refer to Figure 1 and Figure 5 The lampshade 240 has a uniform light emitting surface 243 and a focused light emitting surface 244 . The uniform light emitted by the first light source 220 is emitted from the uniform light emitting surface 243 , and the focused light emitted by the second light source 230 is emitted from the focused light emitting surface 244 .

[0066] Please refer to Figure 1 、 Figure 3 、 Figure 5 and Figure 6 , Figure 3 The figure shows that the shaft mounting frame 120 is provided with a plurality of engaging holes 122, with the center of each engaging hole 122 being equidistant from the shaft member 30. A lampshade 240 is provided with engaging protrusions 242 on the side of the shaft mounting frame 120 that match the engaging holes 122. When the lamp body 20 rotates, the engaging protrusions 242 can be sequentially inserted into the plurality of engaging holes 122, allowing the lamp body 20 to engage with the shaft mounting frame 120 after the lamp body 20 completes its rotation, thereby ensuring the stability of the lamp body 20 during illumination.

[0067] During rotation, the lamp body 20 can be understood as performing a circular motion with the axis of the rotating shaft 30 as the center and the distance between the engaging hole 122 and the axis of the rotating shaft 30 as the radius. When the engaging protrusion 242 is properly aligned with the engaging hole 122, the lamp body 20 maintains stability during illumination. To further rotate the lamp body 20, the engaging protrusion 242 can be removed from the engaging hole 122, allowing continued rotation.

[0068] Figure 1 When the lamp body 20 is in the first position, the second position and the third position respectively, the engaging protrusions 242 are respectively engaged in different engaging through holes 122 so as to be engaged with the shaft mounting bracket 120 after the lamp body 20 completes its rotation.

[0069] Preferably, the snap-fitting protrusion 242 is a spherical structure, which facilitates the snap-fitting protrusion 242 to be snapped into the snap-fitting through hole 122 and also facilitates its removal from the snap-fitting through hole 122, thereby improving the smoothness and stability of the adjustment of the lamp body 20.

[0070] In an optional embodiment, along the axis direction of the rotating shaft 30 , the ceiling frame 110 has an inner side close to the first through slot 111 and an outer side away from the first through slot 111 , and the rotating shaft mounting frame 120 is connected to the ceiling frame 110 at a position close to the inner side and away from the outer side.

[0071] In an optional embodiment, the plane where the side of the rotating shaft mounting bracket 120 close to the first through slot 111 is located is coplanar with the inner wall of the first through slot 111 .

[0072] It can be understood that the side wall of the lamp body 20 is close to the shaft mounting bracket 120, so that the snap-in protrusion 242 provided on the side wall of the lamp cover 240 close to the shaft mounting bracket 120 matches the snap-in through hole 122; in addition, the shaft mounting bracket 120 can also play a certain guiding role in the rotation of the lamp body 20, thereby improving the stability of the lamp body 20 during the rotation process.

[0073] Preferably, there are two rotating shaft mounting brackets 120 , which are respectively located at the two side edges of the first through slot 111 , so as to further improve the stability of the lamp body 20 during the rotation process.

[0074] Please refer to Figure 5 and Figure 6 , along the length direction of the lamp body 20 Figure 5 In the direction of arrow s1 shown in the figure, the second mounting hole 241 to one end of the lampshade 240 constitutes a first rotating part 2a, and the second mounting hole 241 to the other end of the lampshade 240 constitutes a second rotating part 2b, and the length ratio of the first rotating part 2a to the second rotating part 2b ranges from 1 / 4 to 3 / 4.

[0075] The second light source 230 emits a focused light beam toward the side of the lampshade 240 . The second light source 230 is located at the second rotating portion 2 b . The first light source 220 emits a uniformly distributed light beam toward the bottom of the lampshade 240 .

[0076] The length ratio range of the first rotating part 2a and the second rotating part 2b can, on the one hand, ensure that the snap-fit ​​protrusion 242 can be snapped into the snap-fit ​​through hole 122 in sequence to ensure the stability of the rotation of the lamp body 20; on the other hand, the second rotating part 2b, which is longer than the first rotating part 2a, can improve the long-range capability of the second light source 230 and increase the illumination range of the second light source 230, thereby improving the illumination requirements of the lighting device 100.

[0077] In an alternative embodiment, if Figure 5As shown, the lighting device 100 further includes a first stopper 40 and a second stopper 50. The first stopper 40 is connected to the end of the lamp housing 210. One end of the second stopper 50 is used to be connected to the vehicle interior, and the other end can be connected to the first stopper 40. The driver or passenger acts on the first stopper 40 or on the other end of the lamp body 20 away from the first stopper 40 to cause the first stopper 40 to disengage from the second stopper 50, and the first stopper 40 rotates along with the lamp body 20 around the rotating shaft 30.

[0078] As an example, the first stopper 40 is a magnet and the second stopper 50 is a ferrous metal. As another example, the first stopper 40 is a ferrous metal and the second stopper 50 is a magnet.

[0079] When the lamp body 20 is in the first position, the first limiting member 40 is connected to the second limiting member 50 to ensure that the lamp body 20 can match the bracket 10 when the car is bumpy during driving, thereby ensuring the structural stability of the lighting device 100.

[0080] In an optional embodiment, the bracket 10 further includes a connector 130 connected to the interior of the vehicle. The second stopper 50 can be connected to a surface of the connector 130 near the first stopper 40 or embedded in the connector 130 .

[0081] When the lighting device 100 provided in the embodiment of the present application is not in use, the lamp body 20 is in the first position, that is, Figure 2 and Figure 4 Schematic diagram of the state of the lamp body 20 and the bracket 10 is shown in FIG. When the second light source 230 is needed, one end of the lampshade 240 is pushed to disengage the first stopper 40 at the other end of the lampshade 240 from the second stopper 50, and the lamp body 20 is rotated to the desired angle. The engaging protrusion 242 on the lampshade 240 matches the engaging through hole 122, which can ensure the stability of the lamp body 20 during lighting.

[0082] It should be understood that the above embodiments are exemplary and are not intended to encompass all possible implementations of the claims. Various modifications and variations may be made to the above embodiments without departing from the scope of the present disclosure. Similarly, the various technical features of the above embodiments may be arbitrarily combined to form additional embodiments of the present application that may not be explicitly described. Therefore, the above embodiments merely illustrate several implementations of the present application and do not limit the scope of protection of the patent application.
