[0032] Car ambient lights are typically linear, forming a continuous linear luminous surface. This can lead to problems such as a monotonous lighting effect, a lack of layering, and a lack of a premium feel, which in turn undermines the customer experience. The present invention aims to provide a car ambient light that can create a lighting effect reminiscent of black and white piano keys, enriching the lighting effects and enhancing the three-dimensionality, layering, and premium feel of the ambient light.

[0033] 1 to 7 , the vehicle ambient light provided in the embodiment of the present disclosure includes, for example, a bottom cover 10, a protective cover 11, a power substrate 12, a light source 13, an optical lens 14, a shading member 15, a decorative strip 16, a fixing member 17, and an input wiring harness 18. The optical lens 14 includes a bottom 141, at least two protrusions 142, and a reflecting portion 143. The axes of the bottom 141 and the protrusions 142 are perpendicularly arranged, and the reflecting portion 143 is arranged between the bottom 141 and the light source 13. In the embodiment of the present disclosure, the axis of the protrusion 142 refers to a line connecting the center of the surface of the protrusion 142 away from the bottom 141 and the center of the projection of the protrusion 142 on the bottom 141. The vehicle-mounted ambient light provided by the present disclosure can be installed on a vehicle dashboard, a door interior panel, or other locations. Through the bottom 141, the protrusion 142, and the reflective portion 143, the vehicle-mounted ambient light can present a luminous effect similar to the structure of black and white piano keys, thereby enhancing the three-dimensionality, layering, and luxury of the luminous effect of the vehicle-mounted ambient light, thereby enhancing the customer experience.

[0034] Referring to Figures 1 and 2 , in the embodiments of the present disclosure, a power substrate 12 is used to provide connections between the light source 13 and the interior of the ambient light. In the embodiments of the present disclosure, the power substrate 12 is constructed from, for example, one or a combination of glass fiber cloth, epoxy resin, ceramic, and polytetrafluoroethylene to enhance the overall mechanical strength, heat resistance, and electrical insulation performance of the power substrate 12.

[0035] Please refer to Figures 1 and 2. In an embodiment of the present disclosure, the bottom cover 10 is arranged on one side of the power substrate 12 to provide shielding for the protective cover 11, power substrate 12, light source 13, optical lens 14, shading member 15 and fixing member 17 inside the atmosphere lamp, thereby avoiding exposure of the internal components of the atmosphere lamp, protecting the internal components of the atmosphere lamp from external impact, and avoiding safety problems caused by exposure of the internal components of the atmosphere lamp, and improving the aesthetics of the atmosphere lamp. In an embodiment of the present disclosure, the material of the bottom cover 10 is, for example, one or a combination of polycarbonate, polypropylene or acrylic, so as to improve the mechanical properties, heat resistance and corrosion resistance of the atmosphere lamp. In an embodiment of the present disclosure, the bottom cover 10, the protective cover 11 and the decorative strip 16 are, for example, integrated to improve the mechanical strength and impact resistance of the overall atmosphere lamp housing, but the present disclosure is not limited to this.

[0036] Please refer to Figures 1 and 2. In an embodiment of the present disclosure, the protective cover 11 is arranged on the side of the power substrate 12 away from the bottom cover 10. The bottom cover 10, the protective cover 11 and the decorative strip 16 surround the internal area of ​​the atmosphere lamp, thereby providing shielding for the power substrate 12, the light source 13, the optical lens 14, the shading member 15 and the fixing member 17 in the internal area of ​​the atmosphere lamp to protect them from impact, while preventing safety problems caused by exposure of the internal components of the atmosphere lamp and improving the aesthetics of the atmosphere lamp. In an embodiment of the present disclosure, for example, the protective cover 11 is prepared by an in-mold injection molding process, but the present disclosure is not limited thereto. The protective cover 11 can be prepared by any suitable method known in the art. In an embodiment of the present disclosure, the material of the protective cover 11 includes, for example, one or more of light-transmitting materials such as polycarbonate and organic glass. In the embodiment of the present disclosure, for example, the protective cover 11 is a smoky-colored component that is also light-transmissive. This ensures the light transmittance of the protective cover 11, allowing the protective cover 11 to serve as the light-emitting surface of the ambient light. This allows light emitted by the light source 13 to pass through the protective cover 11, thereby meeting the lighting needs of the user. However, the present disclosure is not limited thereto, and the color of the protective cover 11 can be adjusted according to actual needs.

[0037] 1 and 2 , in an embodiment of the present disclosure, a light source 13 is provided on a power substrate 12 to serve as a light source for the atmosphere light. In an embodiment of the present disclosure, the light source 13 is, for example, an LED lamp bead, which provides a light source for the atmosphere light.

[0038] Referring to Figures 1 to 5 , in the embodiments of the present disclosure, an optical lens 14 is disposed between the light source 13 and the protective cover 11 and is used to focus or diffuse the light emitted by the light source 13 to improve the luminous intensity and uniformity of the ambient light and meet the lighting needs of the customer. In the embodiments of the present disclosure, the optical lens 14 can be, for example, a focusing optical lens or a light-homogenizing optical lens. Alternatively, the optical lens 14 can be, for example, a plano-convex lens, a positive concave-convex lens, an aspheric mirror, a diffraction mirror, a plano-concave optical lens, a biconcave optical lens, or a reflective optical lens.

[0039] Please refer to Figures 1 to 5. In an embodiment of the present disclosure, the optical lens 14 includes a bottom 141, at least two protrusions 142 and a reflecting portion 143. The protrusions 142 are arranged on the same side of the bottom 141, and the axes of the bottom 141 and the protrusions 142 are arranged vertically. The reflecting portion 143 is arranged between the bottom 141 and the light source 13, and the reflecting portion 143 is connected to the bottom 141.

[0040] In the embodiment of the present disclosure, first optical textures are provided on the inner wall of the bottom portion 141 near the power substrate 12 and on the inner wall of the reflective portion 143. The first optical textures are, for example, VDI (Verein Deutscher Ingenieure) textures. The VDI texture values ​​of the first optical textures range from 20 to 40, for example. For example, in the embodiment of the present disclosure, the VDI texture value of the first optical texture can be 38 to reflect light.

[0041] In an embodiment of the present disclosure, a second optical texture is provided on the inner wall of the protrusion 142 near the protective cover 11. The second optical texture is, for example, a VDI texture. The VDI value of the second optical texture ranges from 20 to 40. For example, in an embodiment of the present disclosure, the VDI value of the second optical texture is 28 to achieve a uniform light effect.

[0042] In the embodiment of the present disclosure, light emitted by light source 13 first enters reflective portion 143. Because the first optical texture is provided on the inner wall of reflective portion 143, the light is reflected by reflective portion 143 and then transmitted to base 141. Because the first optical texture is provided on the inner wall of base 141 near power substrate 12, the light entering base 141 is reflected onto the inner wall of protrusion 142 near protective cover 11. Because the second optical texture is provided on the inner wall of protrusion 142 near protective cover 11, the light passing through protrusion 142 is homogenized by the second optical texture. The uniform light passes through protrusion 142 and diffuses onto protective cover 11.

[0043] Please refer to Figures 2 to 5. In an embodiment of the present disclosure, the protrusions 142 are, for example, equidistantly distributed on the bottom 141. The distance between two adjacent protrusions 142 ranges from 3 mm to 10 mm, for example. For example, the distance between two adjacent protrusions 142 can be 5 mm. The shape of the protrusion 142 is, for example, one or a combination of polyhedrons such as a cuboid, a cube, and a tetrahedron, but the present disclosure does not limit the shape of the protrusion 142. The shape of the protrusion 142 can be selected according to the luminous effect presented by the atmosphere lamp. In an embodiment of the present disclosure, for example, the protrusion 142 is a light-transmitting component, and the bottom 141 is an opaque component, so as to prevent the light emitted by the light source 13 from passing through the bottom 141, and to concentrate the light on the equidistantly distributed protrusions 142 and pass through the protrusions 142, thereby enriching the luminous effect of the atmosphere lamp.

[0044] Referring to Figures 1 to 5 , in an embodiment of the present disclosure, eighteen protrusions 142 are provided on the base 141, for example. The protrusions 142 are evenly spaced on the base 141, and the distance between adjacent protrusions 142 is 5 mm. In this embodiment of the present disclosure, the protrusions 142 are shaped, for example, as a quadrangular pyramid. The planar surface of the quadrangular pyramid protrusion 142 on the side away from the base 141 is rectangular, and the width of the rectangle is, for example, 3 mm. In this embodiment of the present disclosure, the light source 13 emits white light, for example. The optical lens 14 also includes a light shield 15. The light shield 15 is provided on the base 141 on the same side as the protrusions 142. The light shield 15 fills the space between adjacent protrusions 142 and covers the edges of the base 141, rendering the base 141 opaque. This prevents light emitted by the light source 13 from escaping from the base 141, thereby concentrating the light on the protrusions 142, creating a lighting effect reminiscent of black and white piano keys. In the embodiment of the present disclosure, the reflective portion 143 , the light shielding member 15 , the bottom portion 141 and the protrusion 142 are, for example, integrally provided.

[0045] As shown in Figures 2 and 4 of the present disclosure, the portion of the light shielding member 15 that fills between adjacent protrusions 142 can be a protruding structure. In other words, the portion of the light shielding member 15 that fills between adjacent protrusions 142 is higher than the portion of the light shielding member 15 that covers other areas of the bottom 141. In addition, the height of the protruding structure of the light shielding member 15 from the bottom 141 is lower than the height of the protrusions 142 from the bottom 141.

[0046] Referring to Figures 1 and 2, in one embodiment of the present disclosure, the ambient light further includes a decorative strip 16. The decorative strip 16 is, for example, disposed between the protective cover 11 and the bottom cover 10 to shield and protect the internal components of the ambient light, thereby enhancing the aesthetics of the ambient light and avoiding safety issues caused by exposure of the internal components of the ambient light. In an embodiment of the present disclosure, the decorative strip 16 can be opaque. For example, the surface of the decorative strip 16 can be painted to increase its opacity, thereby concentrating the light emitted by the light source 13 on the protective cover 11 to avoid light scattering.

[0047] Please refer to Figures 1 and 6. In an embodiment of the present disclosure, the ambient light further includes a fixing member 17. The fixing member 17 is, for example, disposed between the bottom cover 10, the protective cover 11, the power substrate 12, the light source 13, the optical lens 14, the shading member 15, the decorative strip 16, and the input wiring harness 18 to connect the internal components of the ambient light into one. In an embodiment of the present disclosure, the fixing member 17 is, for example, used to connect the corresponding components by a combination of one or more connection methods such as threaded connection, pin connection, welding connection, snap connection, expansion connection, or rivet connection to securely connect the internal components of the ambient light. In this embodiment, for example, the fixing member 17 can connect the corresponding components by a snap connection. In this case, the material of the snap is, for example, metal to improve the mechanical properties of the fixing member 17.

[0048] As shown in Figures 6 and 7 , in the embodiment of the present disclosure, the ambient light further includes an input wiring harness 18. One end of the input wiring harness 18 passes through the bottom cover 10 and is electrically connected to the power substrate 12. The other end of the input wiring harness 18, away from the bottom cover 10, is connected to an external power source, providing power to the ambient light and driving the light source 13 on the power substrate 12 to emit light.

[0049] To sum up, the present disclosure provides an atmosphere lamp, which can present the luminous effect of black and white piano keys through the bottom and at least two protrusions perpendicular to the bottom, thereby enriching the luminous effect of the atmosphere lamp, enhancing the three-dimensionality, layering and high-end sense of the luminous effect of the atmosphere lamp, and thus enhancing the customer experience.

[0050] Obviously, those skilled in the art may make various modifications and variations to the embodiments of the present disclosure without departing from the spirit and scope of the present disclosure. The embodiments of the present disclosure disclosed above are merely intended to better explain the principles and practical applications of the present disclosure, thereby enabling those skilled in the art to better understand and utilize the present disclosure, and are not intended to limit the present disclosure. The present disclosure is limited only by the full scope of the claims and their equivalents.
