[0027] Figure 1 The three-dimensional diagram of the lighting device 100 of the present invention is schematically shown. Figure 2 The front view of the lighting device according to the present invention is shown as an example. Figure 1 and 2 As shown, the lighting device includes: a light-emitting module 101, which is configured to emit light; a light-guiding element 102, which is configured to receive light from the light-emitting module 101, and conduct and emit the light; a bracket 103, which is configured to provide support and fixation for the light-emitting element 101 and the light-guiding element 102; wherein the light-emitting module 101 is configured at one end of the light-guiding element 102.

[0028] The light emitting module 101 includes a light source and a carrier on which the light source is arranged, wherein the light source can be any suitable light emitting device, such as a halogen bulb, a xenon lamp, an LED, a laser, etc., and the light source can be arranged on the carrier according to actual needs. As an example, the lighting module can also include a circuit board, such as a PCB, on which the light source is mounted.

[0029] In one example, the light guide element 102 is made of a light-transmitting material, such as, but not limited to, polymethyl methacrylate (PMMA), polycarbonate (PC), etc., so as to ensure that light can propagate in the light guide element and be emitted.

[0030] In one example, the light emitting module 101 includes a housing 1011 configured to accommodate a light source and a carrier for arranging the light source.

[0031] like Figure 4As shown, in one example, a groove 1013 is provided on the housing 1011 of the light-emitting module 101, which is configured to cooperate with the first protrusion 1021 at the end of the light-guiding element 102 to position the light-guiding element and the light-emitting module 101. The groove 1013 is provided in a direction perpendicular to the extension direction of the light-guiding element 102, and can be provided on one side wall of the housing 1011, or on both side walls of the housing 1011 at the same time. The present invention does not impose specific restrictions. By providing the groove 1013 and making it cooperate with the protrusion 1021 at the end of the light-guiding element 102, the positioning accuracy between the light source in the light-emitting module 101 and the light-guiding element 102 can be ensured, thereby improving the light effect.

[0032] In one example, in a direction perpendicular to the extension of the light guide element 102, one of the bracket 103 and the housing 1011 is provided with an opening 105, and the other is provided with a second protrusion 106, wherein the opening 105 and the second protrusion 106 provided on one of the two cooperate with each other to fix the bracket 103 and the light-emitting module 101. Figure 3 As shown, the bracket 103 is provided with an opening 105, the housing 1011 of the light-emitting module 101 is provided with a second protrusion 106, and the second protrusion 106 on the housing 1011 is inserted into the opening 105 on the bracket 103 to fix the bracket 103 and the housing 1011. Of course, the second protrusion 106 can also be provided on the bracket 103, and the opening can be provided on the housing 1011 of the light-emitting module 101, and the present invention does not make any specific limitation.

[0033] In one example, in the extension direction of the light guide element 102, the bracket 103 includes a buckle 1031. Figure 3 As shown, the buckle 1031 extends in a direction perpendicular to the extension direction of the light guide element 102, and its end contacts the side wall of the housing 1021. The buckle 1031 can provide a fixing and positioning function between the housing 1021 and the bracket to a certain extent, especially when the light guide element 102 and the bracket 103 have a large length dimension.

[0034] Specifically, Figure 3 As shown, there is a gap between the main body of the buckle 1031 and the side wall of the housing 1021. When the light guide element 102 and the bracket 103 have a large length dimension, since the light emitting module 101 is positioned at the end of the light guide element 102, the positioning distance between the light emitting module 101 and the light guide plate 102 is too long, and the relative position between the light emitting module 101 and the bracket 103 may be deviated. The gap between the buckle 1031 and the side wall of the housing 1021 can allow the light emitting module 101 and the bracket 103 to have a positional offset to a certain extent, absorb the offset, improve the positioning accuracy of the light emitting module 101 and the bracket 103, and increase the reliability of fixation.

[0035] In a specific example, the buckle 1031 is an elastic buckle. When the light emitting module 101 and the bracket 103 are offset, the elastic buckle can be deformed and absorb the position offset between the light emitting module 101 and the bracket 103, thereby improving the reliability of assembly and fixation.

[0036] According to the design of the present invention, the lighting device can absorb the offset within about 2 mm between the light emitting module 101 and the bracket 103. The size design of the buckle and the interference amount between the light emitting module and the bracket can be adjusted according to the position tolerance value between the light emitting module and the bracket, and the present invention does not specifically limit it.

[0037] In one example, the buckle 1031 is formed integrally with the bracket 103. Forming the buckle 1031 integrally with the bracket 103 can effectively simplify the production process and the installation process, save the space occupied by the lighting device, and thus save costs.

[0038] In one example, if Figure 3 As shown, the housing 1011 is provided with a third protrusion 1014, which is configured to cooperate with the buckle 1031. Providing the protrusion on the housing 1011 can facilitate the design or adjustment of the mold and other processing processes.

[0039] In one example, if Figure 1-4 As shown, the lighting device 100 includes two light-emitting modules 101, which are respectively arranged at the two ends of the light-guiding element 102. When the light-guiding element 102 has a large length, light entering from only one end thereof may not ensure the uniformity of the light-emitting effect. Arranging a light-emitting module 101 at each end of the light-guiding element 102 can effectively ensure the uniformity of the light-emitting effect. Moreover, by setting an RGB light source, a mixed light dynamic effect can also be generated.

[0040] In another example, the lighting device 100 may include multiple light-emitting modules 101 as needed, and the present invention does not limit the number of light-emitting modules 101. Accordingly, a corresponding light-incoming port needs to be formed on the light-guiding element 102 to cooperate with it. Multiple light-emitting modules 101 can further meet different lighting requirements, ensure light-emitting effects, and achieve diversified lighting.

[0041] In one example, if Figure 1-2 As shown, the light guide element 102 and the bracket 103 are provided with mutually cooperating positioning structures 108. In order to ensure the positioning effect, the positioning structure 108 can be arranged at the middle position of the light guide element 102 along the reverse direction of its extension.

[0042] According to the lighting device 100 of the present application, the lighting device 100 can be used as an interior lighting of a motor vehicle to provide interior lighting functions, such as ambient lighting. Of course, it can also be used to realize other lighting or signal indication functions such as turn signals, brake lights, side marker lights, parking lights, daytime running lights, position lights, grille lights, etc.

[0043] According to the design of the present invention, the lighting device can absorb the offset between the light-emitting module and the bracket, thereby improving the optical accuracy and the reliability of positioning and fixing.

[0044] In addition, the present invention also provides a vehicle, the vehicle comprising the aforementioned lighting device. The vehicle at least has the beneficial effects brought by the aforementioned lighting device 100. The term "vehicle" mentioned herein may refer to any type of vehicle, such as a motor vehicle, a motorcycle, or any other mobile machine capable of carrying at least one passenger or used to transport people or goods.

[0045] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, but that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
