[0001] The utility model relates to the technical field of automobile atmosphere lamps, in particular to an annular light guide, an annular atmosphere lamp and a cup holder. Background Art

[0002] A light guide is a structural component that guides the light emitted by an LED from a PCB to the front panel or a light-emitting position. This structural component is generally made of PC or PMMA material and has excellent light-guiding performance.

[0003] Referring to patent CN 217540533 U, this patented solution utilizes a structure in which multiple lamp heads are connected to an annular light guide through corresponding light guides. This avoids overlapping light guide points and makes the light guide's light guiding effect more uniform. However, this patented solution still has the following problems: the position where the light guide connects to the annular light guide receives light from both the light guide itself and the previous light guide, making this position brighter than other positions on the annular light guide. However, the light output of the entire annular light guide is still not uniform and perfect. Utility Model Content

[0004] In order to solve the technical problem that the light emitting effect of an annular light guide is not uniform, the utility model provides an annular light guide, an annular atmosphere light and a cup holder.

[0005] The technical solution is as follows:

[0006] The first aspect of the present application relates to an annular light guide, comprising: a light guide body, the light guide body comprising at least two light guide bars, each of the light guide bars comprising a light input section and a light guiding section, the tail end of each light input section being connected to the head end of the corresponding light guiding section, the light guiding sections being connected end to end in sequence to form an annular structure, and the tail end of each light guiding section being provided with a low-flux light-emitting section with a reduced cross-sectional area.

[0007] When using the above annular light guide, a low-flux light-emitting segment is provided at the position where the light guide segment connects to the light input segment, that is, the position where two adjacent light guide segments are connected, to avoid the higher brightness due to the access of overlapping light at this position, making the light output of the entire annular light guide more uniform and harmonious.

[0008] In some embodiments, each of the low-flux light-emitting segments has a flat structure, and the light-emitting band of each low-flux light-emitting segment is located on the side edge away from the adjacent light-guiding segment, and together with the light-emitting surface of each light-guiding segment, forms a complete annular light-emitting surface.

[0009] In some embodiments, reinforcing ribs are provided on one side or both sides of each low-flux light-emitting segment in the thickness direction.

[0010] In some embodiments, the reinforcing ribs are all strip-shaped structures, and both ends of each reinforcing rib extend to two adjacent light guide segments respectively.

[0011] In some embodiments, the reinforcing ribs are all located at positions corresponding to the low-flux light-emitting segments away from the light-emitting strips.

[0012] In some embodiments, the lengths of the light guide segments are the same, and the light input segments emit light in a circular forward direction and are evenly distributed.

[0013] The second aspect of the present application relates to an annular atmosphere lamp, comprising the above-mentioned annular light guide, a light guide bracket adapted to the light guide body, and lamp heads respectively installed at the head ends of each light input segment, wherein the light guide body is installed on the light guide bracket, the head end faces of each light input segment are light input surfaces, and the light-emitting surfaces of each lamp head are respectively facing the light input surfaces of the corresponding light input segments.

[0014] The above ring-shaped ambient light can be installed in any location where a ring-shaped ambient light is needed through the light guide bracket. It is easy to install and has a wide range of applicability. The ring-shaped light guide used in the ring-shaped ambient light has a more uniform and harmonious light output effect, which enhances the sense of luxury and comfort of the ambient light.

[0015] A third aspect of the present application relates to a cup holder, comprising a cup holder shell and the aforementioned annular ambient light, wherein the light guide bracket is mounted on the cup holder shell, an annular light-transmitting band adapted to the light guide body is provided on the cup holder shell, and the light guide body surrounds the annular light-transmitting band.

[0016] The above cup holder not only has a lighting effect, making it easy to take and place the cup, but also has a sense of art, atmosphere and technology, which enhances the pleasure of the cup holder user. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0023] like Figures 1 to 4 As shown, an annular light guide includes a light guide body 1, which is composed of at least two light guide bars 11. Each light guide bar 11 includes a light input section 111 and a light guiding section 112. The tail end of each light input section 111 is connected to the head end of the corresponding light guiding section 112. The light guiding path of each light guide bar 11 is as follows: light enters from the head end of the light input section 111, passes through the entire light guide bar 11, and is emitted from the tail end of the light guiding section 112. The light guiding sections 112 are connected end to end in sequence to form an annular structure. The number of light guide bars 11 is determined according to the length of the annular light guide. In this embodiment, the annular light guide is composed of two light guide bars 11. The length of the light guiding section 112 of each light guide bar 11 is the same. Each light input section 111 emits light in a circular forward direction and is evenly distributed, ensuring the overall uniformity of the annular light guide. The light guide body 1 is preferably integrally formed, with high strength, stable and reliable structure, and a small number of molds, which reduces production costs.

[0024] Furthermore, the tail end of each light-guiding segment 112 is provided with a low-flux light-emitting segment 112a of reduced cross-sectional area. Each low-flux light-emitting segment 112a has a flat structure. The side of each low-flux light-emitting segment 112a adjacent to the adjacent light-guiding segment 112 is integrated with the adjacent light-guiding segment 112, and the side edge of the other side forms a respective light-emitting strip 112b. Each light-emitting strip 112b, together with the light-emitting surface of each light-guiding segment 112, forms a complete annular light-emitting surface. By controlling the thickness of the low-flux light-emitting segment 112a, the brightness of the light-emitting strip 112b can be controlled, avoiding the problem of excessive brightness at the intersection of two adjacent light-guiding segments 112 due to light overlap, thereby achieving the effect of uniform lighting of the annular light guide. Reinforcing ribs 112c are provided on one or both sides of the thickness direction of each low-flux light-emitting segment 112a. The reinforcing ribs 112c are all strip-shaped, and the ends of each reinforcing rib 112c extend to the two adjacent light-guiding segments 112. The reinforcing ribs 112c prevent the ring-shaped light guide structure from being too weak due to the thinning of the low-flux light-emitting segments 112a. Furthermore, the strip-shaped structure of the reinforcing ribs 112c does not affect the uniformity of the light guide. The reinforcing ribs 112c are located away from the light strips 112b, corresponding to the low-flux light-emitting segments 112a, without affecting the light output.

[0025] like Figure 5As shown, a ring-shaped atmosphere lamp includes the above-mentioned ring-shaped light guide, light guide bracket 3 and lamp head 4. The light guide body 1 is installed on the light guide bracket 3. In this embodiment, a light guide mounting groove compatible with the light guide body 1 is provided on the light guide bracket 3, and the light guide body 1 is embedded in the light guide mounting groove of the light guide bracket 3. This installation method can protect the ring-shaped light guide during the installation and use of the ring-shaped atmosphere lamp and avoid damage to the ring-shaped light guide. The head end of each light-inlet segment 111 is respectively connected to the lamp head 4, and the head end face of each light-inlet segment 111 is a light-inlet surface, and the light-emitting surface of each lamp head 4 is respectively facing the light-inlet surface of the corresponding light-inlet segment 111. The ring-shaped atmosphere lamp is suitable for a variety of scenes, such as car handles, car cup holders, etc., occupies little space, has a uniform light output effect, and can enhance the atmosphere and sense of technology in the use scene.

[0026] like Figure 5 As shown, a cup holder includes a cup holder housing 2 and the aforementioned annular ambient light. The cup holder housing 2 has a recessed center portion forming a placement slot 22, the upper edge of which includes an annular cup holder rim 23. A light guide bracket 3 is mounted on the cup holder housing 2. An annular light-transmitting band 21 is provided on the cup holder housing 2, matching the light guide body 1. The light guide body 1 surrounds the annular light-transmitting band 21, with the annular luminous surface of the light guide body 1 facing the annular light-transmitting band 21. In this embodiment, the light guide bracket 3 is mounted around the circumferential outer wall of the upper end of the placement slot 22, close to the bottom surface of the cup holder rim 23. This installation method is stable and reliable, and does not occupy excess space.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present invention. Under the guidance of the present invention, ordinary technicians in this field can make various similar expressions without violating the purpose and claims of the present invention. Such changes fall within the scope of protection of the present invention.
