Furthermore, features defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] like Figure 1As shown, in some prior vehicle lamps 100', the decorative frame 10' blocks one side of the light guide plate 20', resulting in dark spots in the light guide plate 20'.

[0032] To solve this problem, the following refers to Figures 2-3 A vehicle lamp 100 according to the first aspect of the present application is described.

[0033] As Figure 2 As shown, the vehicle lamp 100 according to the embodiment of the present application comprises a decorative frame 10, a light guide plate 20 and a light source 30.

[0034] The decorative frame 10, as a component of the vehicle lamp 100, plays a certain beautifying role, and at the same time provides certain protection and support for the overall structure of the vehicle lamp 100.

[0035] The light guide plate 20 is responsible for guiding and distributing the light emitted by the light source 30 to achieve the lighting effect.

[0036] Here, the light guide plate 20 has opposite light-incident surface 21 and light-emitting surface 22. The light-incident surface 21 is the side through which light enters the light guide plate 20.

[0037] Optionally, the light-incident surface 21 can directly receive the irradiation of the light source 30, at which time the light emitted by the light source 30 will enter the interior of the light guide plate 20 without obstruction. In addition, the light-incident surface 21 can also indirectly receive light through some refraction, such as lenses, mirrors and other optical elements. These refraction elements can refract the light emitted by the light source into the light guide plate 20 according to a specific angle and direction, thereby achieving control of the entry of light.

[0038] The light-emitting surface 22 can be a smooth surface, or have a texture or pattern.

[0039] The light guide plate 20 also has a ring-shaped side surface 23 connected between the light-incident surface 21 and the light-emitting surface 22, and the ring-shaped side surface 23 comprises a first side surface 231 and a second side surface 232, and the decorative frame 10 is sleeved and connected to the first side surface 231.

[0040] Through the connection of the first side surface 231 and the decorative frame 10, the overall tight fit and stable connection of the vehicle lamp 100 can be improved.

[0041] In some optional embodiments, the first side surface 231 can be connected to the decorative frame 10 through a glue layer or the like. This connection ensures that the decorative frame 10 is accurately and firmly sleeved on the first side surface 231, thereby enhancing the overall structural stability of the vehicle lamp 100, and also achieving seamless docking between the decorative frame 10 and the light guide plate 20, and improving the appearance consistency of the vehicle lamp 100.

[0042] The light source 30 is located on the side of the light guide plate 20 provided with the light inlet face 21. The light emitted by the light source 30 can enter the light guide plate 20 through the light inlet face 21 and be emitted from the light outlet face 22 after being scattered in the light guide plate 20. In this way, the light can be efficiently introduced into the light guide plate 20, and the light can be fully utilized and the loss can be reduced.

[0043] Optionally, optical elements such as a reflective sheet and a diffusion sheet can be arranged between the light guide plate 20 and the light source 30.

[0044] In combination Figure 1 , the side of the light guide plate 20' in the vehicle lamp 100' is partially blocked by the decorative frame, so that the light cannot be effectively transmitted to the light outlet face, thereby forming a "triangular blind area". This not only reduces the light intensity of this part, but also causes dark spots due to uneven light distribution, thereby affecting the visual effect and light efficiency of the vehicle lamp. In order to solve the above problems, in combination Figure 2 , the second side 232 of the vehicle lamp 100 is connected to the first side 231 and the light outlet face 22, and the second side 232 is arranged to extend in a direction away from the center of the light outlet face 22 in a direction toward the light outlet face 22. A wedge-shaped gap 204 is formed between the second side 232 and the decorative frame 10.

[0045] The wedge-shaped gap 204 avoids the decorative frame 10 directly blocking the light of the second side 232. The inclined second side 232 serves as a light guiding structure, which can more uniformly guide the light from the inside of the light guide plate 20 to the light outlet face 22, thereby improving the uniformity and consistency of the light.

[0046] In some optional embodiments, the second side 232 is a plane or a smooth curved surface.

[0047] When the second side 232 is a plane, it provides a simple and efficient light transmission interface, so that the light maintains a relatively consistent propagation direction during the propagation from the inside of the light guide plate 20 to the light outlet face 22, thereby reducing light scattering or reflection caused by the change of the interface. At the same time, the plane is easy to manufacture and process, thereby reducing the production cost.

[0048] When the second side 232 is a smooth curved surface, it can provide a more gentle guidance. The curved surface can guide the light to be more uniformly scattered and reflected in the light guide plate 20, thereby reducing the formation of bright spots and dark spots and improving the brightness uniformity of the light outlet face 22.

[0049] According to some optional embodiments of the present application, the connection between the first side 231 and the second side 232 is located on the side of the decorative frame 10 away from the light source 30.

[0050] In combination Figure 2The connection between the first side surface 231 and the second side surface 232 does not directly face or is not adjacent to the light source 30. This can reduce the possibility of light entering the connection, thereby effectively avoiding the refraction phenomenon caused by the direct illumination of the light source to the connection. In this way, the risk of forming unnecessary bright spots on the light-emitting surface 22 can be reduced, and the light can pass through the predetermined area and be uniformly released.

[0051] In some optional embodiments, the light source 30 includes a plurality of lamp beads 31 arranged at intervals.

[0052] First, since the light emitted by each lamp bead 31 will superimpose on each other during propagation, by arranging a plurality of lamp beads 31 at intervals, the distribution of light in the light guide plate 20 or the illumination area can be ensured to be more uniform, thereby reducing dark areas and bright spots and improving the overall illumination effect.

[0053] Secondly, the plurality of lamp beads 31 can emit light at the same time, which can increase the brightness of the illumination area.

[0054] In some specific embodiments, in combination with Figure 3 The connection between the first side surface 231 and the second side surface 232 is a turning line 205. The lamp bead 31 closest to the turning line 205 is a near-edge lamp bead 311, the radiation surface S1 of the near-edge lamp bead 311 to the turning line 205 is a reference surface, and the second side surface 232 is on the reference surface.

[0055] Since the near-edge lamp bead 311 is closest to the turning line 205, the light emitted by the near-edge lamp bead 311 is the most concentrated and intense. By setting the second side surface 232 on the reference surface and gradually tilting away from the center in the direction of the light-emitting surface 22, the obstruction of the light by the decorative frame 10 can be reduced.

[0056] This structure forms a wedge-shaped gap 204 between the second side surface 232 and the decorative frame 10, thereby optimizing the light path. The light of the near-edge lamp bead 311 enters the inside of the light guide plate 20 and is guided by the inclination angle of the second side surface 232 and is uniformly dispersed to the entire light-emitting surface 22. This not only improves the utilization rate of light, but also improves the light distribution of the light-emitting surface 22, eliminates the dark spot problem caused by the decorative frame 10, and improves the overall visual effect and light efficiency of the vehicle lamp 100.

[0057] In some specific embodiments, as Figure 2 shown, the vehicle lamp 100 further includes a bracket 40, a lamp shell 50, and a lamp cover 60. The light source 30 is mounted on the bracket 40. The bracket 40 and the decorative frame 10 are both mounted on the lamp shell 50. The lamp cover 60 is mounted on the lamp shell 50 and covers the light guide plate 20.

[0058] The bracket 40 is a support structure inside the vehicle lamp 100, used to fix the light source member 30. It provides a stable mounting platform for the light source, ensuring its position is accurate and will not shift due to vibrations during vehicle travel.

[0059] The lamp shell 50 is the outer casing of the vehicle lamp 100, serving to protect the internal components. It not only provides a mounting base for the bracket 40, decorative frame 10, and other internal elements, but also effectively prevents external environmental factors such as moisture and dust from affecting the vehicle lamp 100.

[0060] The decorative frame 10 is located at the edge of the light guide plate 20, acting as a connecting bridge between the light guide plate 20 and the lamp shell 50, helping to maintain the stability of the light guide plate 20. At the same time, the decorative frame 10 can enhance the appearance consistency of the vehicle lamp 100 and also serve as a certain light shielding function to prevent light from leaking out from the side.

[0061] The lamp cover 60 is installed on the lamp shell 50, covering the light guide plate 20, and serves a dual role of protection and light diffusion. On the one hand, the lamp cover 60 can prevent external objects from directly contacting the light guide plate 20. On the other hand, the lamp cover 60 can be provided with special textures or coatings to optimize light scattering, making the light output more uniform and soft.

[0062] Specifically, the bracket 40 and the decorative frame 10 can be detachably mounted on the lamp shell 50.

[0063] This allows the vehicle lamp 100 to easily replace or repair parts when needed.

[0064] Alternatively, the bracket 40 and the decorative frame 10 can be installed on the lamp shell 50 through one or a combination of several connection methods such as bolt connection, buckle connection, adhesive connection, or magnetic attraction connection.

[0065] In some optional embodiments, the light guide plate 20 and the decorative frame 10 are connected by welding.

[0066] Firstly, welding can form a relatively strong and stable connection point, ensuring the tight connection between the light guide plate 20 and the decorative frame 10. This connection method can withstand greater mechanical stress, reducing the impact of vibrations during vehicle travel. Welded connections provide longer-term reliability.

[0067] Secondly, the welded connection can form a seamless seal between the light guide plate 20 and the decorative frame 10, further preventing moisture, dust, and other contaminants from entering the interior, improving the reliability of the vehicle lamp 100.

[0068] For example, Figures 4-5As shown, the combined lamp 1000 according to the second aspect of the utility model comprises at least two lamp bodies which are spliced, at least one of the lamp bodies is the vehicle lamp 100 according to the first aspect of the utility model, and the second side surface 232 is located at one side of the light guide plate 20 which faces the other lamp body.

[0069] In the above technical solution, the combined lamp 1000 is composed of multiple independent lamp bodies which are spliced together.

[0070] Optionally, each lamp body can be a complete vehicle lamp 100 unit which has its own light source, light guide plate 20, support 40, decorative frame 10 and lampshade 60 and the like.

[0071] By using the vehicle lamp 100 according to the first aspect, the second side surface 232 gradually moves away from the center of the light emitting surface 22 in the direction facing the light emitting surface 22, forming a wedge-shaped gap 204. In this way, the light propagation path inside a single lamp body is optimized, so that the light intensity near the splicing position is more uniform and has high consistency, and the light intensity difference near the splicing position is reduced.

[0072] In this way, when the two lamp bodies are turned on at the same time, the light distribution at the splicing position is uniform, and the visual effect is as if a large lamp body is emitting light, enhancing the visual coherence of the combined lamp 1000 as a whole, and thus improving the aesthetic appearance.

[0073] According to the vehicle of the third aspect of the utility model, the vehicle comprises the vehicle lamp 100 according to the first aspect of the utility model, or comprises the combined lamp 1000 according to the second aspect of the utility model.

[0074] By using the above vehicle lamp 100 or combined lamp 1000, the light emitting uniformity and consistency of the vehicle lamp 100 are improved, not only enhancing the lighting effect of the vehicle, but also improving the appearance aesthetics of the vehicle.

[0081] The light source 30 is located on the side of the light guide plate 20 provided with the light-incident surface 21.

[0082] The second side surface 232 is connected to the first side surface 231 and the light-emitting surface 22, and is inclinedly arranged in a direction away from the center of the light-emitting surface 22 in a direction towards the light-emitting surface 22. The second side surface 232 and the decorative frame 10 form a wedge-shaped gap 204.

[0083] The second side surface 232 is a plane.

[0084] The connection between the first side surface 231 and the second side surface 232 is located on the side of the decorative frame 10 away from the light source 30.
