Description

Technical Field

[0001] This utility model relates to the field of automotive component technology, and in particular to ambient lighting installed inside a car to create an environmental atmosphere. Background Technology

[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] Known ambient lights include a light-transmitting mask, a light guide, and a light source module. The light guide is positioned on the light-transmitting mask, and the light source module is positioned on the light-incident surface of the corresponding light guide. Light generated by the light source module enters the light guide through the light-incident surface, causing the light-transmitting mask to emit light. Depending on the installation location, the shape of the light guide generally includes straight, curved, irregularly curved, and ring-shaped shapes. Among them, traditional ring-shaped light guides often use a disconnected light guide, that is, a straight light guide is bent into a ring and then the two ends of the light guide are connected. Therefore, when light is transmitted in the light guide, a dark area will be generated at the connection line, making it difficult to distribute light evenly. Furthermore, the gap between the two ends of the connection line requires extremely high mold precision, resulting in high mold costs. Utility Model Content

[0004] The purpose of this invention is to provide a ring-shaped direct ambient light to solve the problems mentioned in the background art.

[0005] The circular direct ambient light provided by this utility model includes the following technical means: a light-transmitting mask formed in a ring shape, with a light guide mounting groove formed around the inner side of the ring shape, and a light source mounting base formed on one side of the light-transmitting mask; a light guide formed in a ring shape having a ring portion corresponding to the light guide mounting groove, the ring portion being a closed ring shape, and an extension portion integrally formed along the tangential direction from the curvature line of the ring portion, the end of the extension portion being formed as a light-incident end face; and a light source module disposed on the light source mounting base, such that the light emission direction of the LED of the light source module is aligned with the light-incident end face.

[0006] The light-transmitting mask is formed in a rectangular or circular ring shape, and the ring portion of the light guide is also formed in a corresponding rectangular or circular ring shape.

[0007] Compared with the prior art, the beneficial effects of this utility model are: by simplifying the light distribution process, the uniformity of light output is significantly improved, while the precision requirements of the mold are greatly reduced, which not only reduces the mold cost, but also makes the assembly simpler and more efficient.

Detailed Implementation

[0010] To facilitate understanding of this utility model, it will be described in detail below with reference to the accompanying drawings and embodiments. The drawings show some, but not all, embodiments of this utility model. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to enable those skilled in the art to gain a more thorough and comprehensive understanding of the contents of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without inventive changes are within the scope of protection of this utility model.

[0011] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0012] like Figures 1 to 3As shown, the annular direct ambient light provided by this utility model includes: a light-transmitting mask 10, a light guide 20, and a light source module 30. The light-transmitting mask 10 is formed in an annular shape, with a light guide mounting groove 102 formed around the inner periphery of the annular shape. A light source mounting base 104 is formed on one side of the light-transmitting mask 10, and a plurality of fastening seats 103 are formed around its periphery. In embodiments of this utility model, the light-transmitting mask 10 can be formed in a rectangular or circular annular shape. More specifically, the light-transmitting mask 10 is formed in a closed annular shape, with a through hole 101 formed in the center. A radially recessed light guide mounting groove 102 is formed around the annular periphery of the through hole 101 (e.g., a light guide mounting groove 102). Figure 4 and Figure 5 As shown, the fastening seat 103 formed around the light-transmitting mask 10 is a component used to fix the light-transmitting mask 10 to the interior of the car. Since the fastening seat 103 is a known structure and is not the focus of this claim, its detailed description is omitted.

[0013] The light guide 20 is an optical element used to conduct light. It is made of a material with excellent light-conducting properties and is formed with an annular portion 203 corresponding to the light guide mounting groove 102. This annular portion 203 is a closed ring shape, and an extension portion 201 is integrally formed along the tangential direction from the curvature of the annular portion 203. The end of the extension portion 201 is formed as a light-incident end face 202. In an embodiment of this invention, the light guide 20 is formed in an annular shape corresponding to the light guide mounting groove 102 of the light-transmitting mask 10; that is, the light guide 20 can be formed in a rectangular or circular ring shape. After the light guide 20 is installed into the light guide mounting groove 102, the extension portion 201 extends along the notch on the side of the light-transmitting mask 10 to a line close to the light source mounting base 104. One side of the light guide 20 may form a plurality of protruding or recessed dot-shaped reflective surfaces along its length to reflect light; that is, when light is transmitted within the light guide 20, some of the light can be reflected by the dot-shaped reflective surfaces to the light-emitting surfaces in the opposite direction.

[0014] The light source module 30 is a component for generating light. It is mounted on the light source mounting base 104 in conjunction with the lamp cover 40, such that the light emission direction of the LED (not shown) of the light source module 30 corresponds to the light incident end face 202 of the light guide 20. More specifically, the light source module 30 includes a circuit board 301 and LEDs (not shown) electrically connected to the circuit board 301. The circuit board 301 is connected to a power cord 302, and one end of the power cord 302 is provided with a power connector 303 for connecting to the power supply of the vehicle. The lamp cover 40 includes an upper cover 402 and a lower cover 401. The lower cover 401 has a groove 4011. The circuit board 301 of the light source module 30, together with the LED, is placed into the groove 4011. The upper cover 402 is then placed over the lower cover 401 and fixed. At the same time, the LED is aligned with the lamp hole (not shown) reserved in the lower cover 401. The light source module 30 and the lamp cover 40 are installed and fixed together to the light source mounting base 104, so that the light output direction of the LED is aligned with the light input end face 202 of the light guide 20.

[0015] With the aforementioned ambient light structure of this utility model, when the light source module 30 is powered on and the LED emits light, the generated light is projected into the light guide 20 from the light-incident end face 202 and conducted within the light guide 20. Part of the light conducted within the light guide 20 is reflected by the reflective surface of the light guide 20 to produce a light-emitting effect, and simultaneously emits light through the transparent light-transmitting mask 10. Since the light guide 20 of this utility model is a one-piece molded continuous ring shape without any breaks or connecting lines, when light is conducted within the light guide 20, dark areas will not be generated at the breaks or connecting lines, making uniform light distribution easier. Furthermore, the precision requirements for the mold are not as high, which can reduce mold costs.

[0016] The embodiments described above are merely preferred embodiments of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various changes and modifications without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
