Description

Technical Field

[0001] This utility model relates to the field of automotive lighting technology, specifically to vehicle lights, and more particularly to a ring-shaped light-emitting system and vehicle lights. Background Technology

[0002] With the development of the automotive manufacturing industry, lighting fixtures are becoming increasingly diverse and innovative in design, leading to a growing demand for ring-shaped front lights. For ring-shaped signal lights, the main solutions are thick-walled reflective or light-guided types; the thick-walled solution involves a larger number of light sources and is therefore more expensive.

[0003] Due to the influence of the headlight design, the existing light guides and thick-walled components have uneven power distribution, resulting in poor image quality. Thermal cutting cannot achieve a multi-ring, multi-layered dynamic lighting effect. Utility Model Content

[0004] The technical problem to be solved by this utility model is: in order to solve the technical problems of poor lighting effect and poor imaging quality in the prior art, this utility model provides a ring-shaped light-emitting system and vehicle light, which can avoid generating excess light, improve the imaging quality of the optical structure, and optimize the uniformity of lighting.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a ring-shaped light-emitting system, comprising: a light source; a light guide corresponding to the light source, the light guide including a light-incident end and a light-emitting surface, the light emitted from the light source entering the light-incident end and exiting from the light-emitting surface; a thick-walled member corresponding to the light guide, the thick-walled member including a light-incident surface and a light-emitting surface, the light-incident surface being located in the light-emitting direction of the light-emitting surface, and the light entering the light-incident surface and exiting directly from the light-emitting surface; both the light-incident surface and the light-emitting surface are annular structures, and the projections of the light-incident surface and the light-emitting surface in the axial direction at least partially overlap.

[0006] This utility model's ring-shaped light-emitting system places the light guide directly in front of the thick-walled component, allowing the light emitted from the light-emitting surface to penetrate into the thick-walled component, thus avoiding the generation of excess light. This greatly improves the imaging quality of the optical structure, reduces the number of light sources, lowers heat resistance requirements, and saves costs.

[0007] Furthermore, in order to create a multi-layered lighting effect, the number of light guides and thick-walled components is at least two.

[0008] Furthermore, in order to achieve the lighting effect of the multi-ring shape, at least two of the thick-walled components are sequentially nested inward along the radial direction, and at least two of the light guides are arranged at intervals along the radial direction.

[0009] Furthermore, in order to improve the lighting effect, the light-incident surfaces of the multiple thick-walled components are spaced apart on the axis, and the light-emitting surfaces of the multiple thick-walled components are approximately located on the same plane.

[0010] Furthermore, in order to obtain different lighting effects, the thick-walled component is a two-color thick-walled component.

[0011] Furthermore, in order to block excess light, light-blocking elements are provided on the inner and outer rings of the thick-walled member.

[0012] Furthermore, in order to create a ring-shaped lighting effect, both the light-emitting surface and the light-incident surface are rectangular ring structures.

[0013] Furthermore, in order to further improve the light-gathering effect, the light-incident surface has a light-gathering pattern.

[0014] The technical solution adopted by this utility model to solve its technical problem is: a vehicle lamp, including a housing, a bracket inside the housing, the bracket being provided with the above-mentioned annular light-emitting system, and a lampshade located at the front end of the annular light-emitting system on the housing.

[0015] Furthermore, the bracket has mounting grooves arranged in a stepped manner along the axial direction, and multiple light guides are disposed in the mounting grooves. The light guides are spaced apart in both the axial and radial directions. The thick-walled components are connected by light-blocking components to form a whole and then mounted on the bracket.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. The ring-shaped light-emitting system and vehicle light of this utility model adopts ring-shaped light guides and thick-walled components facing each other, so that the light-emitting surface and the light-incident surface can correspond, thereby improving the imaging quality of the optical structure. Moreover, multiple light guides and thick-walled components can form a multi-layer ring structure, resulting in a multi-ring shape and a multi-layer lighting effect.

[0018] 2. The ring-shaped light-emitting system and vehicle lights of this utility model have one light guide component corresponding to one light source, which can reduce the number of light sources, reduce heat resistance requirements, save costs, and facilitate assembly.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0025] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, features defined with "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.

[0026] 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.

[0027] like Figure 1 As shown, a vehicle light includes a housing 3, a bracket 4 inside the housing 3, an annular light-emitting system on the bracket 4, and a lampshade 5 located at the front end of the annular light-emitting system on the housing 3. The lampshade 5 and the housing 3 are welded together.

[0028] Specifically, the ring-shaped light-emitting system includes: a light source 6, a light guide 1 corresponding to the light source 6, and a thick-walled component 2 corresponding to the light guide 1. In the headlight, the light emitted from the light source 6 enters the light guide 1 and is directed towards the thick-walled component 2. Finally, the thick-walled component 2 directs the light through the lamp cover 5 and disperses it. The light path is as follows: Figure 1 As indicated by the middle arrow.

[0029] like Figure 3As shown, preferably, the light guide 1 includes a light-incident end 11 and a light-emitting surface 12. The light emitted from the light source 6 enters the light-incident end 11 and exits from the light-emitting surface 12. The plane containing the light-incident end 11 and the light-emitting surface 12 are on different planes, and the light source 6 is located behind the light-incident end 11. The light guide 1 is prior art, and its structure will not be described in detail here.

[0030] Specifically, the thick-walled component 2 includes an incident light surface 21 and an exit light surface 22. The incident light surface 21 is located in the light-emitting direction of the light-emitting surface 12, and the light rays enter the incident light surface 21 and then exit directly from the exit light surface 22.

[0031] Preferably, both the light-incident surface 21 and the light-emitting surface 12 are annular structures, and the projections of the light-incident surface 21 and the light-emitting surface 12 in the axial direction at least partially overlap. The light-incident surface 21 is a light-emitting surface and faces the light guide. The light emitted from the light-emitting surface 12 directly enters the light-incident surface 21, passes through the light-emitting surface 22, and then exits directly. This avoids the generation of excess light and improves the imaging quality.

[0032] In Embodiment 2, based on Embodiment 1, the bracket 4 has mounting grooves 41 arranged in a stepped manner along the axial direction. There are three mounting grooves 41, three light guides 1, and three thick-walled members 2. The light guides 1 are disposed within the mounting grooves 41, and are spaced apart in both the axial and radial directions. The thick-walled members 2 are connected by light-blocking members 7 to form a whole and are then mounted on the bracket 4.

[0033] like Figure 2 As shown, preferably, three thick-walled components 2 are sequentially nested radially inward. Three light guides 1 are arranged radially at intervals. The light-incident surfaces 21 of the three thick-walled components 2 are spaced apart on the axis, and the light-exit surfaces 22 of the three thick-walled components 2 are approximately located on the same plane.

[0034] To meet the design requirements and dynamic lighting, the light guide 1 and the thick-walled component 2 are designed in a stepped distribution, similar to a nested doll, which can increase space utilization, reduce component size, and lower costs.

[0035] The outer surface of the light-emitting surface 22 has a serrated pattern. When it is not lit, it can show a crystal-like pattern effect. When it is lit, it can refract and diffuse light, thereby improving the overall uniformity.

[0036] Preferably, light-blocking elements 7 are provided on the inner and outer rings of the thick-walled member 2. The light-blocking elements 7 can prevent the light rays between the thick-walled members 2 from interfering with each other, thereby forming ring-shaped light rays with distinct different levels.

[0037] Specifically, the bracket 4 also includes conventional components such as a control circuit board (not shown in the figure) and decorative rings (not shown in the figure). The control circuit board can control the light source 6 to turn on or off, thereby achieving a multi-ring, multi-layered dynamic lighting effect.

[0038] In Example 3, based on Example 1, the light-incident surface 21 has a light-focusing pattern, which can further concentrate the light emitted from the light-emitting surface 12.

[0039] Specifically, both the light-emitting surface 12 and the light-incident surface 21 are rectangular ring structures. Of course, they can also be circular, elliptical, or other common ring structures.

[0040] In summary, the ring-shaped light-emitting system and vehicle light of this invention can avoid generating excess light, improve the imaging quality of the optical structure, and optimize the uniformity of illumination.

[0041] The above description is based on the preferred embodiments of this utility model. Through the above description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined by the scope of the claims.
