[0027] Unless otherwise specified, all terms used herein (including technical and scientific terms) shall have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. It should also be understood that terms (e.g., those defined in common dictionaries) shall be interpreted as having the meaning consistent with their meaning in the context of the relevant art and shall not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

[0028] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] For ease of understanding this application, Figure 3 The text provides the up and down directions. These directions are used to indicate the orientation or positional relationship of the various components of the ambient lighting.

[0030] Specifically, such as Figures 1 to 3 As shown, the ambient light disclosed in this embodiment of the present invention includes a first light source 1, a second light source 2, a central lampshade 3, a light guide plate 4, and a light guide device 5. The light guide plate 4 has a hollow ring structure, the central lampshade 3 is placed on the light guide plate 4, and the light guide device 5 is arranged around the outside of the light guide plate 4, with the edge of the central lampshade 3 mounted on the light guide device 5. The first light source 1 is located directly below the center point of the central lampshade 3, and the light emitted by the first light source 1 illuminates the central lampshade 3, making the entire surface of the central lampshade 3 illuminate. The second light source 2 is located directly below the light guide plate 4, and part of the light emitted by the second light source 2 enters the light guide plate 4 and is conducted along the light guide plate 4, while the other part directly illuminates the central lampshade 3, further enhancing the overall illumination effect of the central lampshade 3. Preferably, the central lampshade 3 has a bowl-shaped structure, with the bowl opening of the central lampshade 3 facing the light guide plate 4, and the upper end of the light guide plate 4 located inside the bowl opening of the central lampshade 3, that is, the central lampshade 3 is inverted and covers the light guide plate 4.

[0031] The light guide device 5 includes multiple light guide components 51, each of which is a hollow ring structure. These components are arranged sequentially and stacked. Specifically, the multiple first light guide components 51 share the same central axis and are arranged sequentially from the inside out, with adjacent components having varying heights, giving the entire light guide device 5 a stepped shape. This sequential arrangement and stacking of the multiple light guide components 51 creates a three-dimensional lighting effect for the ambient light.

[0032] Furthermore, each light guide component 51 includes a light guide light source 511, a light conductor 512, a reflector 513, and a diffuser 514. The light conductor 512, reflector 513, and diffuser 514 are all hollow annular structures, with the light conductor 512 being a strip structure and the reflector 513 and diffuser 514 being plate structures. The light guide light source 511 is positioned below the light conductor 512, and the reflector 513 and diffuser 514 are connected at an angle, with the reflector 513 located directly above the light conductor 512 and the diffuser 514 located to the side of the light conductor 512. Preferably, the reflector 513 and diffuser 514 are formed using an integral injection molding process, reducing the manufacturing difficulty of the reflector 513 and diffuser 514.

[0033] The reflector 513 has a diffuse reflection layer (not shown in the figure) on its surface facing away from the light conductor 512. This diffuse reflection allows light incident on the reflector 513 to diffuse, creating a gradual diffuse reflection effect in the ambient light and enhancing its technological feel. It should be noted that the diffuse reflection layer is an optical functional layer whose surface structure or material properties allow incident light to scatter (i.e., diffuse reflection) rather than specular reflection. The diffuse reflection layer allows light to diffuse evenly in multiple directions, reducing glare caused by direct reflection and improving the uniformity and softness of the light. Preferably, the diffuse reflection layer is formed by creating a micro-uneven structure on the surface of the reflector 513. It should be noted that since the diffuse reflection layer of the reflector 513 of a single light guide component 51 is located on the surface of the reflector 513 facing away from the light conductor 512, the reflector 513 of a single light guide component 51 primarily reflects light from adjacent light guide components 51 and light from the light guide plate 4.

[0034] By setting up a central lampshade 3, a light guide plate 4, and a light guide component 51 with a height difference, a three-dimensional lighting effect of the ambient light is achieved by using multi-layered spatially staggered light-emitting surfaces. Furthermore, by using the light conductor 512 on the light guide component 51 in conjunction with the reflector 513 and the diffuser lampshade 514, linear light emission is combined with surface light emission, thereby creating a gradient lighting effect in the three-dimensional lighting, ultimately making the ambient light effect more three-dimensional and more technological.

[0035] In one embodiment, such as Figure 3 and Figure 4 As shown, a reflective surface 41 is provided on the top of the light guide plate 4, directly opposite the second light source 2. That is, the reflective surface 41 is provided on the upper part of the light guide plate 4 away from the second light source 2. The reflective surface 41 is used to reflect the light transmitted within the light guide plate 4. The light emitted by the second light source 2 enters the light guide plate 4 and is transmitted along the light guide plate 4. Then, the light is reflected by the reflective surface 41, changing the direction of the light and exiting the light guide plate 4. This causes the light from the second light source 2 to change direction and shine towards the edge of the central lampshade 3, making the edge of the central lampshade 3 emit a linear light effect and enhancing the three-dimensional light emission effect of the central lampshade 3.

[0036] In one embodiment, an aluminum plating layer (not shown in the figure) is provided on the reflective surface 41, which can improve the reflectivity and uniformity of the reflective surface 41.

[0037] In one embodiment, such as Figure 4 As shown, the light guide plate 4 includes a vertically connected light guide section 42 and a light emitting section 43. The second light source 2 is located directly below the light guide section 42, and the reflective surface 41 is located directly above the light guide section 42. By setting the light guide plate 4 into a bent shape, the transmission direction of the light passing through the light guide plate 4 is changed, allowing the light to be better directed towards the edge of the central lampshade 3, thereby improving the light emission effect at the edge of the central lampshade 3.

[0038] In one embodiment, the angle between the reflective surface 41 and the central axis o of the light guide 42 is C, and 120°≤C≤150°. It should be noted that the central axis o refers to the direction from which the second light source 2 faces the light guide 42. Limiting the angle C between the reflective surface 41 and the central axis o of the light guide 42 ensures that the reflective surface 41 can receive more reflected light, thereby improving the edge light emission effect of the central lampshade 3.

[0039] In one embodiment, the distance between the diffuser 514 and the light conductor 512 is 1mm to 5mm, which ensures that the diffuser 514 can better receive the light from the light conductor 512, so that the light distribution is uniform and light interference is avoided; and it can also control the size of the ambient light to meet the miniaturization requirements.

[0040] In one embodiment, the height of the diffuser 514 along the direction from the reflector 513 toward the light conductor 512 is 3mm to 10mm. The thickness of the diffuser 514 along the direction from the light conductor 512 is 2mm to 4mm. Controlling the height and thickness of the diffuser 514 can reduce light loss.

[0041] In one embodiment, such as Figure 3 As shown, the ambient light also includes a light-blocking plate 6, which is a hollow ring structure. The light-blocking plate 6 is arranged around the outside of the light guide plate 4 and is located below the reflector 513 closest to the light guide plate 4. The light-blocking plate 6 separates the light guide plate 4 and the light guide device 5, preventing light emitted by the second light source 2 from entering the light guide device 5 and causing light crosstalk, thus ensuring that different positions of the ambient light have unique lighting effects.

[0042] In one embodiment, the central lampshade 3 is heart-shaped, and both the light guide plate 4 and the light guide device 5 are heart-shaped, ensuring that the light guide plate 4 and the light guide device 5 extend around the shape of the central lampshade 3, making the ambient light's luminous shape heart-shaped and enhancing the attractiveness of the ambient light product. Preferably, the number of light guide components 51 is four, causing the ambient light to emit multiple layers of luminous surfaces and multiple heart-shaped luminous lines, enhancing the aesthetics of the ambient light.

[0043] In one embodiment, the ambient light also includes a circuit board (not shown in the figure), located below the central lampshade 3. A light guide device 5 is mounted on the circuit board, and the first light source 1, the second light source 2, and the light guide light source 511 are all mounted on the circuit board. By mounting all the light sources on a single circuit board, the ambient light structure is simplified and assembly is convenient.

[0044] In one embodiment, the central lampshade 3 is made of PMMA (polymethyl methacrylate) or PC (polycarbonate). The reflector 513 is made of PC+ABS (a mixture of polycarbonate and acrylonitrile-butadiene-styrene copolymer) and is opaque. The diffuser 514 is made of PMMA or PC, with an organic diffusing agent added to the PMMA or PC, giving it a milky white color. The light-blocking plate 6 is made of PC+ABS and is a black opaque plate.

[0045] To understand this application, the main transmission path of light in ambient lighting is described below. Please refer to... Figure 5 The light emitted by the first light source 1 is mainly directed towards the central lampshade 3, and then towards the human eye, making the central lampshade 3 appear as a luminous surface. The light emitted by the second light source 2 is mainly directed by the light guide plate 4 to illuminate the edge of the central lampshade 3. Part of the light from the edge of the central lampshade 3 is directed towards the human eye, forming a luminous line; part of the light is directed towards the reflector 513 of the light guide device 5 near the light guide plate 4 and then diffusely reflected towards the human eye, forming a reflective surface; secondary light is directed directly towards the central lampshade 3 and then towards the human eye, further enhancing the luminous effect of the central lampshade 3. The light emitted by the light guide light source 511 is directed by the light conductor 512 and then towards the diffuser lampshade 514. Part of the light passes through the diffuser lampshade 514 and is directly directed towards the human eye, forming a luminous line; part of the light passes through the diffuser lampshade 514 and is directed towards the reflector 513 of the adjacent light guide component 51, and then diffusely reflected towards the human eye, forming a diffuse luminous surface. Specifically, as... Figure 6 As shown, the light emitted by multiple light sources on the ambient light forms multiple adjacent light-emitting surfaces and light-emitting lines through different paths, which not only makes the ambient light exhibit a three-dimensional lighting effect, but also provides a gradient three-dimensional lighting effect, ultimately making the ambient light's lighting effect more three-dimensional and more technological.

[0046] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
