[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0026] In the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "matched" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] In addition, it should be noted that in the description of the present invention, it should be noted that the terminology nouns in the various embodiments, such as "upper", "lower", "front", "back" and other words indicating directions, are only for simplifying the description of the positional relationship based on the drawings in the specification, and do not mean that the components and devices referred to must be operated in accordance with the specific directions and specified operations and methods and structures in the specification. Such directional nouns do not constitute a limitation on the present invention.

[0028] like Figure 1-Figure 2 As shown, the atmosphere lamp in this embodiment includes a light source 1, a light guide structure 2, a mask 10, a mask bracket 11, and a lamp back shell. The light source 1 is installed on the lamp back shell, the mask 10 is snap-connected to the mask bracket 11, and the mask bracket 11 is screwed to the main body bracket 12.

[0029] Specifically, the body bracket 12 is screwed to the instrument panel body.

[0030] Specifically, the light guide structure 2 includes a first color layer 3 and a second color layer 4 , wherein the first color layer 3 and the second color layer 4 are matched and arranged by injection molding, and form a channel for conducting light from the light source 1 .

[0031] Specifically, the second color layer 4 is connected to the main body support 12, for example, by snap connection, bonding, or fastening with a fastener.

[0032] Specifically, the first color layer 3 has a first surface 5 facing the light source 1 and extending along the length direction of the first color layer 3, and the first color layer 3 also has a second surface 6. The direction of the channel from the first surface 5 to the second surface 6 along the first color layer 3 is generally consistent, thereby ensuring that most of the light source light can reach the second color layer 4 in a generally straight direction, thereby improving the light transmission efficiency.

[0033] Specifically, the second color layer 4 has a third surface 7, which is arranged opposite to the second surface 6, and the second surface 6 is provided with a protrusion 61 along the length direction of the first color layer 3, and the third surface 7 is provided with a groove 71 along the thickness direction of the second color layer 4. The protrusion 61 and the groove 71 are matched, and the advantages of this design are: 1) ensuring the compactness of the overall structure, so that the shape and outer contour of the joint surface of the protrusion and the groove are as free as possible; 2) ensuring the uniformity of the wall thickness of the joint surface, avoiding the shrinkage of the product due to the excessive wall thickness; 3) adapting to the feasibility of mold development.

[0034] It should be noted that the groove 71 can be Figure 2 The shown one is an arc-shaped concave surface, which may also be a recessed space or an inclined slope.

[0035] Specifically, the second color layer 4 further has a fourth light emitting surface 8 and a fifth surface 9, and at least a portion of the fourth light emitting surface 8 is arranged in parallel with the fifth surface.

[0036] Specifically, to adapt to the shape, the second color layer 4 includes a top, a side and a bottom, and the top and the bottom are snap-fitted with the main support 12. Of course, the third surface 7, the fourth light-emitting surface 8, and the fifth surface 9 are located on the side.

[0037] Specifically, the fifth surface 9 is provided with a beam splitter tooth 91 , which can enhance the reflective effect of the fifth surface 9 and enhance the visual brightness of the ambient light.

[0038] In particular, the beam-splitting teeth 91 are gradually densely distributed along the fifth surface 9 from top to bottom. For example, when the beam-splitting teeth 91 are distributed along the fifth surface 9, the number of the beam-splitting teeth 91 distributed on the upper part of the fifth surface 9 is less than the number of the beam-splitting teeth 91 distributed on the lower part of the fifth surface 9, that is, the beam-splitting teeth 91 gradually become denser from the upper part to the lower part of the fifth surface 9, so that the brightness of the atmosphere light presents an increasing gradient effect from top to bottom, and a very high brightness of the atmosphere light can be obtained in some parts to meet consumer needs.

[0039] Specifically, the cross section of the light splitting teeth 91 is at least one of a circular, rectangular, tooth-shaped and irregular shape. By setting the light splitting teeth 91 to different pattern effects, an optical effect of a corresponding pattern can be formed after lighting.

[0040] like Figure 3As shown, specifically, the fifth surface 9 is provided with a plurality of splitter teeth 91. When the light source 1 enters the second color layer 4 and is reflected on the fifth surface 9, the plurality of splitter teeth 91 concentrates the reflection of the light source 1 and eliminates scattered light, thereby ensuring that the boundary of the light irradiated to the mask 10 is clearer and has a good lighting effect.

[0041] Specifically, the material of the first color layer 3 is polycarbonate (PC) material. The use of polycarbonate (PC) material arranged in the first color layer can improve light transmission efficiency and reduce light loss.

[0042] Specifically, the material of the second color layer 4 is polymethyl methacrylate (PMMA) material.

[0043] Specifically, light-distributing ink is printed on the light-guiding structure 2. By printing the light-distributing ink on the light-guiding structure 2, the light-guiding structure 2 has the effects of light conduction and light diffusion at the same time. On the premise of meeting the functions, there is no need to add additional structures such as light-distributing plates, and excellent atmosphere lighting effects can be achieved in a smaller envelope space.

[0044] Specifically, the mask 10 is a smoky transparent lampshade, which can present a crystal-like transparency when the ambient light is turned on, and the music rhythm frequency can be presented through the refraction of the shape of the outer lampshade.

[0045] Another embodiment of the present invention provides a vehicle, comprising the above-mentioned atmosphere lamp. The vehicle may be a car, and the advantages of the car over the prior art are the same as those of the above-mentioned atmosphere lamp, which will not be described again.

[0046] Although the utility model is disclosed as above, the protection scope of the utility model is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the utility model, and these changes and modifications will fall within the protection scope of the utility model.
