[0002] With the technological advancements in ambient lighting and the improvement of the passenger experience, multi-color and multi-changing ambient lighting is widely used in automotive interior design. Ambient lighting not only provides users with a superior driving experience but also offers some assistance in driving and reducing driver fatigue.

[0003] With the continuous development of the automotive market, consumers are increasingly demanding higher levels of comfort and personalization in car interiors. Ambient lighting, as a crucial element in enhancing the quality of the in-car environment, is gradually becoming a focus for both automakers and consumers. Circular ambient lighting can create a unique and comfortable in-car atmosphere, enhancing the user's driving experience and possessing broad market prospects.

[0004] Most commonly known automotive ambient lighting designs employ a linear light-emitting form (i.e., a linear light guide strip), resulting in a monotonous and simple design with a narrow luminous area and poor visibility. This is increasingly failing to meet today's consumers' demands for comfort and personalization in-car environments, especially given the fierce competition within the electric vehicle industry. Statistics show that over 70% of consumers consider interior personalization a key factor when choosing a vehicle and are willing to pay for a more trendy and atmospheric interior. Furthermore, consumers have high demands for interior space, necessitating redesigns of components to accommodate ambient lighting and prevent other interior parts from excessively taking up space. Utility Model Content

[0005] In order to overcome the shortcomings of existing technology, the purpose of this utility model is to solve the problems of the monotonous shape and space occupation of traditional ambient lights, while enhancing the additional functions and value of ambient lights, so as to meet consumers' demand for more trendy vehicle interiors and break out of the predicament of traditional vehicle ambient lights.

[0006] The ring-shaped light guide plate ambient light provided by this utility model includes: The base has an annular disc seat, wherein the annular disc seat has an annular groove; A light guide plate has a light guide plate body corresponding to the annular groove, and a light guide strip extends integrally along the tangential direction of the side of the light guide plate body. The end face of the light guide strip serves as the light entrance end face for light to enter the light guide strip, and the light guide plate is disposed in the annular groove. A light-transmitting cover having an annular shape, the light-transmitting cover being assembled with the base, such that the light guide plate is located between the base and the light-transmitting cover; and A light source module is connected to the light guide strip, so that the light emission direction of the LED of the light source module corresponds to the light incident end face; The light generated by the LED is transmitted through the light-incident end face into the light guide strip and light guide plate to emit light.

[0007] In one specific embodiment, the base can be formed as comprising two integrally formed annular disks connected together; the light-transmitting cover can be formed as comprising two integrally formed annular covers connected together, to be combined with the base; and two independent light guide plates can be respectively disposed in the two annular disks.

[0008] In one specific embodiment, the two bases and the two light-transmitting covers can be integrally formed into an "8" shape.

[0009] Preferably, an opening can be formed on the side of each of the annular disk bases, through which the light guide strip extends out of the base.

[0010] Preferably, the radial end face shape of the light-incident end face can be formed into a plum blossom shape.

[0011] In one specific embodiment, the light source module may include: A lamp holder is formed with a lamp tube, and a lamp hole is formed at the end of the lamp tube; The circuit board is electrically connected to the LED and connector terminals. The circuit board is located inside the lamp holder so that the light emission direction of the LED corresponds to the lamp hole. The lamp cover is assembled and installed on the lamp holder, so that the circuit board and the LED are accommodated between the lamp holder and the lamp cover, and the connector terminal extends out of the lamp holder.

[0012] Compared with the prior art, the present invention has the following advantages: 1. More Unique Design: This application presents a unique "8" shape with an infinite loop concept, breaking away from the constraints of traditional straight lines or regular geometric shapes in ambient lighting, and possessing a strong sense of artistry and technology. When the light is turned on, the continuously flowing light shuttles through the "8" shape, like light and shadow swimming, creating a strong visual impact.

[0013] 2. Wider light-emitting surface: This application provides a wider light-emitting surface with a plate-shaped light guide plate, so that light can be projected out in a larger area and in a more dispersed manner, with a viewing angle close to 180°, avoiding the problems of light concentration and poor viewing angle that are easy to occur with traditional narrow light-emitting surfaces.

[0014] 3. More complete light-emitting effect: This application provides a single, complete ring-shaped light guide plate that is molded in one piece, breaking the status quo that traditional injection-molded light guides are mostly linear. It realizes the transformation of linear ambient lights from linear light emission to surface light emission, which can achieve more complex and artistic light-emitting patterns. Moreover, it improves the strength, making it less prone to breakage during transportation and production.

[0015] 4. Single LED achieves surface emission: This application achieves the transformation of ambient light from linear emission to surface emission by projecting light through a single LED via a light guide strip to a light guide plate. Unlike traditional solutions that require multiple LEDs in series or complex light guide structures, this greatly simplifies the light source module and reduces costs.

[0016] 5. Higher added value: The hollow space of the "8"-shaped ambient light can be used to arrange devices such as speakers and cup holders, realizing the linkage between the components arranged around the ambient light and achieving a decorative effect of 1+1 greater than 2.

[0017] 6. Effectively reduce the bright spot phenomenon at the light-incident end: This application forms the light-incident end face of the light guide strip into a radial end face in the shape of a plum blossom, which can effectively reduce the bright spot phenomenon at the light-incident end, thereby reducing the uniform light distance and reserving more shaping space for the light-emitting area.

[0018] 7. Simpler structure and lower cost: The ambient light of this application is small and compact in size, simple in structure, easy to install, occupies little space, and has low manufacturing cost. Attached Figure Description

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0022] like Figure 1 and Figure 2 As shown, the annular light guide plate type ambient light provided by this utility model includes: a base 10, a light-transmitting cover 20, a light guide plate 30, and a light source module 40. Wherein, as... Figure 5 As shown, the base 10 can be formed as annular disc seats 10A and 10B with two circular rings, and the sides of the two annular disc seats 10A and 10B are connected together in an integral molding manner to form an "8" shape outline. The two annular disc seats 10A and 10B have recessed annular grooves 101A and 101B respectively on one axial side. The sides of the annular disc seats 10A and 10B are respectively provided with openings 102A and 102B that connect the annular grooves 101A and 101B with the outside.

[0023] like Figure 4 As shown, the light-transmitting cover 20 is a light-transmitting element for assembly with the base 10. It can be formed with two annular covers 20A and 20B, and the sides of the two annular covers 20A and 20B are connected together in an integral molding manner to form an "8" shape outline corresponding to the base 10, so that the shapes of the light-transmitting cover 20 and the base 10 correspond to each other and can be combined with each other. When the light-transmitting cover 20 and the base 10 are combined, a space is formed between them that can accommodate the light guide plate 30. The combination of the light-transmitting cover 20 and the base 10 can be fixed by ultrasonic fusion technology, or by mechanical fixing elements or any suitable means. Since the fixing method is a known technology and is not the focus of the protection claimed in this application, its detailed description is omitted.

[0024] like Figure 6As shown, the light guide plate 30 is integrally formed from an optical material with excellent light transmission properties. Due to the figure-eight shaped base 10 and the light-transmitting cover 20, it has two separate disc-shaped light guide plate bodies 30A and 30B corresponding to the annular grooves 101A and 101B. Light guide strips 301A and 301B extend integrally along the tangential direction of the sides of the light guide plate bodies 30A and 30B. The end faces of the light guide strips 301A and 301B serve as light-incident end faces 3011A and 3011B for light to enter the light guide strips 301A and 301B. Preferably, the radial end faces of the light-incident end faces 3011A and 3011B are formed in a quincunx shape (e.g.,...). Figure 7 As shown in the diagram, to avoid glare in the area when light enters the light-incident end face, the light guide plates 30A and 30B of the light guide plate 30 are respectively placed in the annular grooves 101A and 101B, while the light guide strips 301A and 301B pass through the openings 102A and 102B of the annular disk seats 10A and 10B, respectively. After the light guide plate 30 is installed on the base 10, the light-transmitting cover 20 is then assembled and installed on the base 10, so that the light guide plate 30 is located in the space between the base 10 and the light-transmitting cover 20. Furthermore, in order to install the light source module 40 on the light guide strips 301A and 301B, connectors 302A and 302B for connecting the light source module 40A and 40B can be respectively provided at the ends of the light guide strips 301A and 301B.

[0025] like Figure 3 As shown, light source modules 40A and 40B are components for generating light, including lamp covers 401A and 401B, lamp holders 402A and 402B, and circuit boards 403A and 403B. Lamp holders 402A and 402B each form a lamp tube 4021, with a lamp hole 4022 at the end of each tube. The lamp hole 4022 allows the ends of light guide strips 301A and 301B to be fixed therein. After the circuit boards 403A and 403B are installed inside the lamp holders 402A and 402B, the lamp covers 401A and 401B are assembled into the lamp holders 402A and 402B. This allows the LEDs 4032, electrically connected to the circuit boards 403A and 403B, to be located inside the lamp tube 4021, while simultaneously enabling the LEDs... The light emission direction of 4032 corresponds to the light-incident end faces 3011A and 3011B of the light guides 301A and 301B; the connector terminal 4033, which is electrically connected to the side of the circuit boards 403A and 403B, protrudes beyond the lamp holders 402A and 402B. The connector terminal 4033 is used to connect the power cord, and then connect to the power supply of the car.

[0026] Based on the annular light guide plate ambient light structure of this application, when the light source module 40 is powered on and the LED 4032 emits light, the generated light is projected from the light-incident end faces 3011A and 3011B of the light guide strips 301A and 301B into the light guide strips 301A and 301B, and then conducted into the light guide plate bodies 30A and 30B to produce a light-emitting effect. The light is also visible through the light-transmitting cover 20. Furthermore, since the radial end faces of the light-incident end faces 3011A and 3011B are formed in a plum blossom shape, it can prevent the light from causing a bright spot phenomenon in the light-incident area when it enters the light-incident end face.

[0027] The ambient light of this application is small and compact in size, simple in structure, easy to install, occupies little space, and has low manufacturing cost. In addition, the ring-shaped light guide plate ambient light of this application has a hollowed-out central hole, which can be fully utilized to place a speaker or cup holder, effectively utilizing fragmented space and maximizing the decorative effect.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
