Description

Technical Field

[0001] The utility model relates to the technical field of small automobile interior lamps, and in particular to a linear light guide for a door panel atmosphere lamp and a mounting structure thereof. Background Art

[0002] As people gradually become more aware of car interiors, more and more models are adding ambient lighting to enhance the sense of luxury and technology in car interiors. Among them, linear ambient lighting is mainly placed on door interior panels and car dashboards.

[0003] In order to achieve the layout of the wrap-around interior atmosphere lights, the spacing between the light-emitting segments of adjacent linear atmosphere lights is required to be as small as possible to improve the final presentation effect. For the door interior panel, the internal space is particularly narrow. If the lamp head is directly installed at the end of the linear light guide without turning, it often causes the problem of large spacing between the light-emitting segments of the linear atmosphere lights. Therefore, an installation method has emerged on the market in which the end of the linear light guide is turned and then connected to the lamp head, which can shorten the spacing between the light-emitting segments of adjacent linear atmosphere lights to a certain extent.

[0004] However, see Figure 1 , the light-emitting segment of the linear atmosphere light on the door panel still has a blind spot at the end of the light-emitting strip of the lampshade, resulting in poor brightness at the end of the light-emitting strip of the lampshade, or even failure to light up, affecting the overall lighting effect of the linear atmosphere light.

[0005] Solving the above problems has become a top priority. Utility Model Content

[0025] The following further describes the present invention in conjunction with embodiments and the drawings.

[0026] Embodiment 1 of the linear light guide of the door panel atmosphere lamp:

[0027] As Figure 2 and Figure 5As shown, a linear light guide for a door panel atmosphere light mainly comprises a linear light guide body 1 with a linear structure, the linear light guide body 1 comprises a light emitting segment 13 with a linear structure, a first optical pattern 131 extending along its length direction is provided on the circumferential outer wall of the light emitting segment 13, a portion of the circumferential outer wall of the light emitting segment 13 opposite to the first optical pattern 131 is a light emitting segment light emitting portion 132 with a linear structure, the first optical pattern 131 is preferably an optical pattern with a total reflection function, when light is transmitted in the light emitting segment 13, the first optical pattern 131 reflects the light toward the light emitting segment light emitting portion 132, and the light emitting segment light emitting portion 132 emits the light outward.

[0028] The linear light guide body 1 in this embodiment can be light-inlet at one end or at both ends. Specifically, at least one end of the light-emitting segment 13 is sequentially connected to the light-mixing light-guiding segment 12 and the light-inlet segment 11, that is, the light-emitting segment 13 can be sequentially connected to the light-mixing light-guiding segment 12 and the light-inlet segment 11 at one end or at both ends.

[0029] Due to the limitation of the installation position, in order to ensure the installation of the lamp holder, the angle between at least one of the light input segments 11 and the light emitting segment 13 is greater than or equal to 80° and less than or equal to 160°, and the mixing light guide segment 12 located between the light input segment 11 and the light emitting segment 13 is integrally formed with an end light emitting extension structure 14. The light emitting direction of the light emitting surface 141 of the end light emitting extension structure 14 is the same as the light emitting direction of the light emitting portion 132 of the light emitting segment, and is located on the extension line of the corresponding end of the light emitting portion 132 of the light emitting segment.

[0030] Therefore, by using the above-mentioned linear light guide for the door panel atmosphere light, the light-emitting surface 141 of the end light-emitting extension structure 14 can be used as an extension of the light-emitting segment light-emitting portion 132 of the light-emitting segment 13, thereby improving the brightness of the end of the door panel linear atmosphere light and making the brightness of the end of the door panel linear atmosphere light consistent with the brightness of other parts, thereby effectively improving the lighting effect of the door panel linear atmosphere light, and at the same time making the lighting spacing between adjacent linear atmosphere lights as small as possible, thereby improving the overall lighting effect of the wrap-around interior atmosphere light arrangement.

[0031] In this embodiment, the mixed light guide segment 12 provided with the end light-emitting extension structure 14 is an arc structure connected between the corresponding light input segment 11 and the light-emitting segment 13. The end light-emitting extension structure 14 is a strip structure extending outward from the circumferential outer wall of the mixed light guide segment 12. The light-emitting surface 141 is the outer end surface of the end light-emitting extension structure 14, so that the light can be guided to a farther distance. At the same time, the structure is simple and reliable, easy to process and shape, and the mold modification is small.

[0032] Further, the end-emitting extension structure 14 first extends in one direction, and then its outer end bends towards one side, so that the light-emitting direction of the light-emitting surface 141 is the same as that of the light-emitting section light-emitting part 132. Thus, when the light can be guided to a farther distance, the overall thickness of the linear light guide body 1 can be effectively controlled, which is beneficial for arrangement in a narrow space.

[0033] Further, a light-emitting surface pattern is integrally formed on the light-emitting surface 141, ensuring the light-emitting brightness of the light-emitting surface 141.

[0034] Linear light guide of door panel atmosphere light, Embodiment 2:

[0035] As Figure 3 and Figure 6 shown, the main structure of this embodiment is the same as that of the linear light guide of door panel atmosphere light in Embodiment 1, and the difference lies in that: the light mixing light guide section 12 provided with the end-emitting extension structure 14 includes a first light mixing part 121 and a second light mixing part 122 which are both arc structures. The light incident ends of the first light mixing part 121 and the second light mixing part 122 are combined into one body, and the light incident ends of the first light mixing part 121 and the second light mixing part 122 are integrally formed on the light-emitting end of the corresponding light incident section 11. At the same time, the light-emitting end of the first light mixing part 121 is integrally formed on the corresponding end of the light-emitting section 13, and the light-emitting end of the second light mixing part 122 extends in the extension line direction of the light incident section 11. And a section of extended light-emitting section 15 is integrally formed at the light-emitting end of the second light mixing part 122, that is, the light mixing light guide section 12 as a whole has a bifurcated structure.

[0036] In this embodiment, the extended light-emitting section 15 is located on the extension line of the light incident section 11. The outer circumferential wall of the extended light-emitting section 15 has a second optical pattern 151, and the part of the outer circumferential wall of the extended light-emitting section 15 opposite to the second optical pattern 151 is an extended section light-emitting part 152 in a linear structure, and the extended section light-emitting part 152 is located on the extension line of the light-emitting section light-emitting part 132. Therefore, by setting the extended light-emitting section 15 in this embodiment, the lighting length of the linear light guide body 1 can be made longer, so that the lighting distance between adjacent linear atmosphere lights on the door panel is smaller, further enhancing the surrounding effect of the in-vehicle atmosphere light.

[0037] In this embodiment, the end-emitting extension structure 14 is a strip structure integrally formed at both ends on the first light mixing part 121 and the second light mixing part 122, and the end-emitting extension structure 14, the light-emitting section 13 and the extended light-emitting section 15 together form a linear structure. The light-emitting surface 141 is located on one surface in the thickness direction of the end-emitting extension structure 14, so that the gap between the light-emitting section light-emitting part 132 and the extended section light-emitting part 152 can be filled through the light-emitting surface 141, making the whole present a complete linear light emission.

[0038] Specifically, a first light guide strip 121a extending along its length direction is integrally formed on the circumferential outer wall of the first light mixing part 121, and a second light guide strip 122a extending along its length direction is integrally formed on the circumferential outer wall of the second light mixing part 122. One ends of the first light guide strip 121a and the second light guide strip 122a are joined at the junction of the first light mixing part 121 and the second light mixing part 122, and the other ends of the first light guide strip 121a and the second light guide strip 122a are respectively joined to both ends of the end light-emitting extension structure 14. Third optical patterns 142 are formed on the outer edges on both sides in the width direction of the end light-emitting extension structure 14, and the third optical patterns 142 are preferably optical patterns with total reflection function. Through such a design, the first light guide strip 121a and the second light guide strip 122a lead out the light in the first light mixing part 121 and the second light mixing part 122, and then introduce the light into the end light-emitting extension structure 14, so that the end light-emitting extension structure 14 can be smoothly lit up.

[0039] Door panel ambient light linear light guide embodiment 3:

[0040] As Figure 4 and Figure 7 shown, the main structure of this embodiment is the same as that of the door panel ambient light linear light guide embodiment 2, and the difference lies in that: the first light guide strip 121a is not provided on the first light mixing part 121, the second light guide strip 122a is not provided on the second light mixing part 122, and the end light-emitting extension structure 14 is lit by the remaining light emitted from the distal end of the light inlet section 11. Therefore, third optical patterns 142 are formed on the surface of the end light-emitting extension structure 14 on the side away from the light-emitting surface 141 in the thickness direction, and the third optical patterns 142 are preferably optical patterns with total reflection function, so as to improve the brightness of the light-emitting surface 141 as much as possible, so that the brightness of the light-emitting surface 141 is consistent with that of the light-emitting section light-emitting part 132 and the extended section light-emitting part 152.

[0042] Please refer to Figure 2 , an installation structure of a door panel ambient light linear light guide, including a lamp cover 2 and the door panel ambient light linear light guide of the door panel ambient light linear light guide embodiment 1. The lamp cover 2 has a linearly extending light-emitting strip 21, the light-emitting section light-emitting part 132 is located inside the light-emitting strip 21, and the light-emitting surface 141 is located at the corresponding end of the light-emitting strip 21. Through such a design, the end brightness of the light-emitting strip 21 of the lamp cover 2 can be improved, the brightness of each part of the light-emitting strip 21 of the lamp cover 2 is made consistent, and the light-emitting effect of the door panel linear ambient light is improved.

[0043] Installation structure embodiment 2 of the door panel ambient light linear light guide:

[0044] Please refer to Figure 3, the main structure of this embodiment is the same as that of Embodiment 1 of the installation structure of the linear light guide of the door panel ambient light. The difference is that: this embodiment adopts the linear light guide of the door panel ambient light in Embodiment 2. By adopting the linear light guide of the door panel ambient light in Embodiment 2, the end of the light-emitting band 21 can be closer to the end of the lamp cover 2, thereby further reducing the lighting spacing between adjacent linear ambient lights and improving the overall lighting effect.

[0045] Embodiment 3 of the installation structure of the linear light guide of the door panel ambient light:

[0046] Please refer to Figure 4 , the main structure of this embodiment is the same as that of Embodiment 2 of the installation structure of the linear light guide of the door panel ambient light. The difference is that: this embodiment adopts the linear light guide of the door panel ambient light in Embodiment 3.
