[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.

[0028] The quantity of any element in the drawings is for illustration rather than limitation, and any naming is only for distinction and does not have any limiting meaning.

[0029] Next, with reference to several representative embodiments of the present invention, the principles and spirits of the present invention will be elaborated in detail.

[0030] A dynamic atmosphere lamp provided by the present invention with a changeable luminous pattern, as Figures 1 to 5 shown, includes a rotation driving member 1 and a driven member 2. The driven member 2 includes a linkage portion 21 and a fixed portion 22. The linkage portion 21 is in linkage cooperation with the driving end of the rotation driving member 1, and an optical fiber 3 is fixed on the fixed portion 22 so that the optical fiber 3 rotates synchronously with the driven member 2.

[0031] In this embodiment, the rotation driving member 1 is a rotation motor. The rotation driving member 1 serves as a power source to drive the driven member 2 to rotate, and then drives the optical fiber 3 to rotate. The optical fiber 3 is a light-emitting element, and the light emitted by it forms a changing luminous pattern during the rotation. In this embodiment, the optical fiber 3 can achieve the dynamic effect of the atmosphere lamp with fewer LED lamp beads. Different luminous pattern light and shadow changes can be achieved by changing the micro-structure of the atmosphere lamp optical fiber 3 (the pattern of the LED lamp bead combination, the color and brightness of the optical fiber 3 itself, etc.).

[0032] In this embodiment, a linkage member 4 is linked and connected to the driving end of the rotation driving member 1. The linkage member 4 includes a connecting portion 41 and a transmission portion 42. The connecting portion 41 is in linkage cooperation with the rotation driving member 1. Meshing teeth 5 are provided on both the transmission portion 42 and the linkage portion 21. The transmission portion 42 and the linkage portion 21 are in meshing transmission. The transmission portion 42 and the linkage portion 21 are both arranged in a fan-shaped structure. The transmission portion 42 includes a first arc-shaped side wall 421, and the linkage portion 21 includes a second arc-shaped side wall 211. The meshing teeth 5 on the transmission portion 42 are located on the first arc-shaped side wall 421, and the meshing teeth 5 on the linkage portion 21 are located on the second arc-shaped side wall 211.

[0033] In this embodiment, the connecting portion 41 is used to ensure a stable connection and effective power transmission between the rotation driving member 1 and the linkage member 4. The connecting portion 41 is in close fit with the driving end of the rotation driving member 1 through spline connection.

[0034] In this embodiment, the meshing teeth 5 on the linkage portion 21 match the meshing teeth 5 on the transmission portion 42. Through the interaction of the meshing teeth 5, the transmission portion 42 transmits the rotational power to the linkage portion 21, so that when the transmission portion 42 rotates, it can drive the linkage portion 21 to rotate according to a predetermined transmission ratio and direction, realizing a smooth and reliable transmission between the transmission portion 42 and the linkage portion 21.

[0035] In this embodiment, a limiting member 4211 is provided on the first arc-shaped side wall 421. The limiting member 4211 is parallel to the meshing teeth 5. A limiting groove 2111 is provided on the second side wall. The limiting member 4211 corresponds to the limiting groove 2111.

[0036] In this embodiment, there are several meshing teeth 5. The several meshing teeth 5 are evenly distributed along the first arc-shaped side wall 421 and the second arc-shaped side wall 211 respectively. The length of the limiting groove 2111 is greater than the length of the limiting member 4211 which is greater than the length of a single meshing tooth 5. The width of the limiting groove 2111 is greater than the width of the limiting member 4211 which is greater than the width of a single meshing tooth 5. This design allows the limiting member 4211 to have a certain moving space in the limiting groove 2111, while ensuring that the meshing teeth 5 can mesh normally and transmit power. The limiting member 4211 can have a certain axial movement range in the limiting groove 2111, which helps to adapt to the minute deviations and changes during the transmission process, while maintaining the stability and reliability of the transmission.

[0037] In this embodiment, the setting of the limiting member 4211 and the limiting groove 2111 will not interfere with the operation of the meshing teeth 5. At the same time, the cooperation between the limiting member 4211 and the limiting groove 2111 also has certain precision requirements, making it easier to position the transmission part 42 and the linkage part 21 during the assembly process. The interaction between the limiting member 4211 and the limiting groove 2111 can effectively limit the lateral movement of the transmission part 42 and the linkage part 21 during the transmission process, making the transmission more stable and reliable, helping to reduce vibration and noise during the transmission process. Moreover, when the transmission system is subjected to excessive load or abnormal impact, the contact between the limiting member 4211 and the limiting groove 2111 can serve as a safety protection mechanism to prevent the transmission part 42 or the linkage part 21 from being damaged due to overload.

[0038] In this embodiment, both ends of the optical fiber 3 are electrically connected to lamp heads 31. The lamp heads 31 and the optical fiber 3 adopt a non-contact power generation structure. There is a gap between the end faces at both ends of the optical fiber 3 and the lamp heads 31, ensuring that the optical fiber 3 can rotate synchronously with the driven member 2 and guaranteeing the practicability of this atmosphere lamp. In other embodiments, the electromagnetic induction principle can be adopted between the optical fiber 3 and the lamp heads 31 to generate an induced current in the loop where the optical fiber 3 is located, thereby lighting up the optical fiber 3; or, radio wave power transmission can also be used to receive and convert the power through an antenna into direct current or alternating current for the optical fiber 3 to use in various forms. In this embodiment, non-contact power transmission makes the design and installation of the optical fiber 3 more flexible, can get rid of the bondage of traditional electrical connections to a certain extent, and has higher flexibility and higher safety.

[0039] In this embodiment, it further includes a fixing plate 6. The rotation driving member 1 and the driven member 2 are both installed on the fixing plate 6. The fixing plate 6 is fixedly connected with a mask 61. The mask 61 covers the optical fiber 3 to ensure the safety of the optical fiber 3. In this embodiment, the mask 61 is set as a U-shaped structure, and the optical fiber 3 is located in the U-shaped groove.

[0040] In other embodiments, the mask 61 can be set in various forms such as a transparent plate, a light-transmitting plate with a color, a light-transmitting plate with a pattern, and a non-light-transmitting plate with a pattern cutout.

[0041] In this embodiment, the fixing plate 6 is provided with mounting holes 62. The driven member 2 is in a fitting engagement with the mounting holes 62. The setting of the mounting holes 62 allows the driven member 2 to rotate within the mounting holes 62.

[0042] Based on the above description of this specification, those skilled in the art can also understand the terms used as follows. For example, terms indicating orientation or positional relationships such as "upper", "lower", "front", "rear", "left", "right", "width", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings of this specification. They are only for the purpose of facilitating the description of the solution of the present utility model and simplifying the description, rather than explicitly or implicitly indicating that the devices or elements involved must have the specific orientation, be constructed and operate in the specific orientation. Therefore, the above terms of orientation or positional relationships cannot be understood or interpreted as a limitation to the solution of the present utility model.

[0043] In addition, in the description of this specification, the meaning of "a plurality of" is at least two, such as two, three or more, etc., unless otherwise specifically defined.
