Description

Technical Field

[0001] This invention relates to the field of ambient lighting technology, and more particularly to an ambient lighting assembly and a vehicle. Background Technology

[0002] As a core component of vehicle ambient lighting, the light guide directs light emitted from a light source to a specific location and emits light at a given angle to meet the basic requirements of ambient lighting arrangement. Currently, light guides can only emit light along a single specific angle. In practical applications, to achieve better visual effects, it is usually necessary to achieve light emission from two or more angles. Therefore, in related technologies, a dual-light guide scheme is commonly used. However, the dual-light guide scheme leads to an increase in the number of components, weight, assembly time, and development costs of the ambient lighting assembly. Summary of the Invention

The end of the light guide is connected to a light source. The light guide is provided with a first light tooth and a second light tooth. The first light tooth can reflect light along a first direction to the lamp housing, and the second light tooth can reflect light along a second direction to the reflector.

[0008] As a preferred technical solution for the ambient light assembly, the diffuser is provided with a first light-emitting wall and a second light-emitting wall. The light reflected by the first light-emitting tooth enters the light-emitting cavity through the first light-emitting wall, and the light reflected by the second light-emitting tooth enters the light-emitting cavity through the second light-emitting wall.

[0009] As a preferred technical solution for the ambient light assembly, a portion of the surface of the first light-emitting wall located on one side of the light-emitting cavity is coated with an opaque coating to form a first light-emitting area, and the light reflected by the first light teeth enters the light-emitting cavity through the first light-emitting area. And / or, a portion of the surface of the second light-emitting wall located on one side of the light-emitting cavity is coated with an opaque coating to form a second light-emitting area, through which the light reflected by the second light tooth enters the light-emitting cavity.

[0010] As a preferred technical solution for the ambient light assembly, the reflector includes a first reflective layer and a second reflective layer. The first reflective layer is attached to the side of the second reflective layer facing the diffuser. The second reflective layer is fixedly connected to the mounting assembly. The first reflective layer is used to allow light to pass through, and the second reflective layer is used to reflect light.

[0011] As a preferred technical solution for the ambient lighting assembly, the first reflective layer and the second reflective layer are integrally formed by dual-color injection molding.

[0020] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0021] like Figures 1-10As shown, this embodiment of the invention provides an ambient lighting assembly. This assembly is applied to a vehicle and can be used as ambient lighting for the upper or lower part of the dashboard, for the front and rear doors, or for other locations within the vehicle interior. The ambient lighting assembly includes a mounting component, a lamp housing 3, a light guide 5, and a reflector component. The mounting component is used to fixably connect to the dashboard assembly or door assembly. The mounting component includes a base 1 and a housing 2 that are snap-fitted or fixedly connected. Depending on the specific location of the ambient lighting assembly, snap-fit ​​structures or bolt holes are selectively provided on the base 1 and housing 2, and the connection to the dashboard or door is achieved through bolts, screws, or snap-fits. The lamp housing 3 is fixedly connected to the mounting component, for example, through snap-fit ​​connection, adhesive connection, or bolt connection. The lamp housing 3 is made of a light-transmitting material and has a smoked outer surface to soften the light. The lamp housing 3 and the mounting component together form a receiving cavity, within which the light guide 5 and the reflector 7 are fixedly disposed. The end of the light guide 5 is connected to a light source, which can be an LED bead or a PCBA light board. In this embodiment, the light source is preferably a PCBA light board. The structure of the PCBA light board is existing technology in this field and will not be described in detail here. The light guide 5 is provided with a first light tooth 522 and a second light tooth 513. The first light tooth 522 can reflect light along a first direction to the lamp housing 3, and the second light tooth 513 can reflect light along a second direction to the reflector 7. The reflector 7 is used to reflect light incident along the second direction to the lamp housing 3. The first direction and the second direction are set at an angle.

[0022] In this embodiment, the ambient light assembly features a first light tooth 522 and a second light tooth 513 on the light guide 5. The first light tooth 522 reflects light along a first direction to the lamp housing 3, achieving a direct ambient light illumination effect. The second light tooth 513 reflects light along a second direction to the reflector 7, which then reflects the light back to the lamp housing 3, achieving an indirect ambient light illumination effect. Furthermore, the first and second directions are angled together, satisfying the requirement of dual-angle light output from a single light guide 5. By incorporating the reflector 7, both direct and indirect ambient light illumination effects are achieved simultaneously. Compared to the dual-light guide 5 light output scheme in related technologies, this approach reduces the number of components, lowers weight, shortens assembly time, and lowers development costs.

[0023] Furthermore, such as Figures 2-3 and refer to Figures 4-5As shown, the ambient light assembly also includes a bracket 4, which is fixedly installed within the receiving cavity. The bracket 4 has a slot extending along its length. The light guide 5 includes a body 51 with a protruding rib 52 extending along its length. The rib 52 engages with the slot. A first light tooth 522 is located at the end of the rib 52 furthest from the body 51, and a second light tooth 513 is located on the body 51. By engaging the rib 52 with the bracket 4, the light guide 5 is installed while simultaneously allowing sufficient space for the arrangement of the first light tooth 522 at the end furthest from the body 51 and the second light tooth 513 on the body 51, thus avoiding interference. Multiple first light teeth 522 and second light teeth 513 are provided and evenly distributed along the length of the body 51.

[0024] Specifically, please refer to Figures 4-5 As shown, buckles 41 protrude from both opposite side walls of the slot, and a connector 521 is provided at the end of the rib 52 away from the body 51. The connector 521 engages with the buckles 41, and the buckles 41 are used to prevent the connector 521 from coming out of the slot. The buckles 41 have a triangular structure, with their large end facing the bottom of the slot. Two buckles 41 on opposite side walls of the slot form a group, and multiple groups of buckles 41 are evenly arranged on the inner wall of the slot along the extension direction of the slot. The connector 521 has a large end and a small end, and the first optical tooth 522 is provided at the small end of the connector 521. After the connector 521 engages with the buckles 41, the body 51 of the light guide 5 is pressed against the opening of the slot to prevent the light guide 5 from coming out of the slot or moving along the depth direction of the slot. Meanwhile, by setting buckles 41 on both opposite side walls of the slot, the sway of the connector 521 within the slot is further limited, thereby preventing the light guide 5 from swaying and ensuring a secure and reliable installation of the light guide 5. The light guide 5 is not connected to the bracket 4 by screws or clamps, avoiding any adverse effects on the light output of the light guide 5 caused by connecting parts, such as light leakage, obstruction, or light spots. Please refer to... Figure 8As shown, the two ends of the main body 51 are respectively provided with a first connector 511 and a second connector 512. The first connector 511 and the second connector 512 are respectively connected to two light sources. The light sources can be set as light sources of the same color or light sources of different colors, depending on the lighting requirements, and are not specifically limited here. The first light tooth 522 and the second light tooth 513 are both set as arc-shaped teeth or triangular teeth. The first light tooth 522 is recessed in the surface of the rib 52 away from the main body 51, that is, the first light tooth 522 is a groove structure; the second light tooth 513 is recessed in the surface of the main body 51, that is, the second light tooth 513 is a groove structure. The light source of the first connector 511 enters and is transmitted along the light guide 5. When it passes through one side of the tooth surface of the first light tooth 522 and the second light tooth 513, total internal reflection occurs, and it is emitted out of the light guide 5 along the first direction and the second direction, respectively. The light source of the second connector 512 enters and is transmitted along the light guide 5. When it passes the other side of the tooth surface of the first optical tooth 522 and the second optical tooth 513, it undergoes total internal reflection and is emitted out of the light guide 5 along the first direction and the second direction respectively, while merging with the light from the first light source. When the first light source and the second light source are the same color, the brightness can be increased after the light from the first light source and the second light source merge. When the first light source and the second light source are different colors, the color of the final emitted light can also be changed after the light from the first light source and the second light source merge.

[0025] Furthermore, such as Figure 3 and Figure 7 and combined Figure 9 As shown, the ambient light assembly also includes a light diffuser 6, which is fixedly disposed within the receiving cavity. The light diffuser 6 divides the receiving cavity into a light-emitting cavity 101 and a light-emitting cavity 102. A light guide 5 is located within the light-emitting cavity 101, and a reflector 7 is located within the light-emitting cavity 102. The light diffuser 6 enables diffuse reflection of the passing light. Before reaching the lamp housing 3, the light passes through the light diffuser 6. The diffuse reflection by the light diffuser 6 softens the light reaching the lamp housing 3, further enhancing the visual effect of the ambient light. In this embodiment, the light diffuser 6 is made of milky white diffuser PC, which reduces brightness loss while increasing light diffusion to achieve a better soft light effect.

[0026] Specifically, the light-diffusing element 6 is provided with a first light-emitting wall 61 and a second light-emitting wall 62. The light reflected by the first light tooth 522 enters the light-emitting cavity 102 through the first light-emitting wall 61, and the light reflected by the second light tooth 513 enters the light-emitting cavity 102 through the second light-emitting wall 62. This constrains the light emitted from the light-diffusing element 6, so that the light reflected by the first light tooth 522, after being softened by the first light-emitting wall 61, directly illuminates the lamp housing 3; and the light reflected by the second light tooth 513, after being softened by the second light-emitting wall 62, enters the reflector 7 and, after reflection by the reflector 7, enters the lamp housing 3 to emit light.

[0027] Specifically, a portion of the surface of the first light-emitting wall 61 located on one side of the light-emitting cavity 102 is coated with an opaque coating, forming a first light-emitting area 611. Light reflected by the first optical teeth 522 enters the light-emitting cavity 102 through the first light-emitting area 611. And / or, a portion of the surface of the second light-emitting wall 62 located on one side of the light-emitting cavity 102 is coated with an opaque coating, forming a second light-emitting area 621. Light reflected by the second optical teeth 513 enters the light-emitting cavity 102 through the second light-emitting area 621. In this embodiment, the opaque coating is preferably black paint, so that light can only enter the light-emitting cavity 102 from the first light-emitting area 611 and the second light-emitting area 621. Both the first light-emitting area 611 and the second light-emitting area 621 are rectangular. In other embodiments, depending on the shape of the lamp housing 3, the first light-emitting area 611 and the second light-emitting area 621 can be circular, elliptical, or triangular, etc. In this embodiment, to facilitate processing and manufacturing, the entire surface of the soft light component 6 located on one side of the light-emitting cavity 102 is coated with an opaque coating. Then, laser engraving is performed on the first light-emitting area 611 and the second light-emitting area 621. After laser engraving, the first light-emitting area 611 and the second light-emitting area 621 can emit light.

[0028] Furthermore, such as Figure 3 , Figure 6 , Figure 7 and Figure 10As shown, the reflector 7 includes a first reflective layer 71 and a second reflective layer 72. The first reflective layer 71 is attached to the side of the second reflective layer 72 facing the diffuser 6. The second reflective layer 72 is fixedly connected to the mounting assembly. The first reflective layer 71 allows light to pass through, while the second reflective layer 72 reflects light. The light reflected by the second light teeth 513 passes through the second light-emitting area 621 of the diffuser 6 and enters the first reflective layer 71. After passing through the first reflective layer 71, it is reflected at the junction of the second reflective layer 72 and the first reflective layer 71 and exits from the first reflective layer 71, finally entering the lamp housing 3. With this configuration, the light reflected by the second light teeth 513 enters the first reflective layer 71 sequentially after passing through the diffuser 6, changes direction after being reflected by the second reflective layer 72, and exits from the first reflective layer 71. During the process of entering and exiting the first reflective layer 71, the light undergoes a slight degree of refraction and diffuse reflection, which makes the light that finally enters the lamp housing 3 softer. The first reflective layer 71 and the second reflective layer 72 are integrally molded using two-color injection molding, thereby reducing the number of parts and assembly time. Specifically, in this embodiment, the first reflective layer 71 is preferably made of PMMA, and the second reflective layer 72 is preferably made of high-gloss black PC. PMMA has good light transmittance, and the surface of high-gloss black PC has good reflectivity, which not only satisfies the requirement of reflecting light but also allows for further light softening. In addition, features such as concavity, dot matrix, or waves can also be provided on the surface of the first reflective layer 71, so that the light emitted from the first reflective layer 71 to the lamp housing 3 is arranged in a certain pattern, making the ambient light present a better visual effect.

[0029] This invention provides a vehicle including an ambient lighting assembly, which can be a dashboard ambient light or door ambient light. By using the ambient lighting assembly in this embodiment, the number of parts and total weight are reduced, assembly time is shortened, and development costs are lowered. Simultaneously, the ambient lighting effect is softer, enhancing the refined sensory experience for occupants.
