AI Technical Summary
The starry sky effect on the vehicle roof is affected by the misalignment of the light-transmitting holes in the light-blocking layer with the light source of the backlight component, resulting in uneven brightness and impacting the visual effect.
A second light source is introduced into the light source array and positioned within the gaps between the rows of the first light sources. At least a portion of the second light source is offset from the first light source to form a more uniform light source distribution, ensuring that the light-transmitting holes of the light-shielding layer can contain portions of the first and/or second light sources.
It improves the uniformity of ceiling brightness and the starry sky effect, with almost all light-transmitting holes lit up, resulting in small brightness differences and excellent visual effects.

Abstract
Description
Technical Field
[0001] This application relates to the field of vehicle technology, and in particular to an optical trim for vehicles. Background Technology
[0002] Some vehicles are equipped with headliners that create a starry sky effect. For example, such headliners include a backlight with multiple arrayed light sources and a stencil mounted on the side of the backlight facing the vehicle's interior. The stencil has multiple light-transmitting holes through which the light emitted by these light sources shines into the vehicle's interior, creating the starry sky effect.
[0003] However, the light-transmitting holes on the light-shielding layer are not perfectly aligned with the light sources on the backlight components. Some light-transmitting holes correspond to non-light-source areas of the backlight components, resulting in lower brightness in these holes. This may lead to uneven brightness on the ceiling and a poor starry sky effect. Utility Model Content
[0004] To address the aforementioned technical problems, this application proposes an optical trim for vehicles. The optical trim includes a backlight element comprising a light source array formed by multiple light sources; and a light-shielding layer having multiple light-transmitting holes; the light-shielding layer is disposed on the light-emitting surface of the backlight element, and the light emitted by the multiple light sources is adapted to pass through the multiple light-transmitting holes; wherein the light source array includes multiple first light sources arranged in multiple rows along a first direction; a first gap exists between adjacent rows of first light sources; and multiple second light sources disposed within the first gaps; at least a portion of each second light source deviates from the first light source along a second direction perpendicular to the first direction.
[0005] In one embodiment, there is a second gap between adjacent first light sources in each first light source row, and the plurality of second gaps are aligned with each other along a second direction; the plurality of second light sources correspond to the plurality of second gaps respectively.
[0006] In one embodiment, the second light source is rectangular, and the length direction of the second light source is parallel to the first direction.
[0007] In one embodiment, a plurality of first light sources are aligned with each other along a second direction; the light source array also includes a plurality of third light sources, which are located within a first gap, and at least one third light source is disposed between two first light sources aligned along the second direction.
[0008] In one embodiment, each third light source is rectangular, and the length direction of each third light source is parallel to the second direction.
[0009] In one embodiment, the geometric center of each second light source is aligned with the geometric center of each third light source along a first direction; and the plurality of second light sources and the plurality of third light sources are arranged alternately.
[0010] In one embodiment, the light source array further includes a plurality of fourth light sources, which are respectively disposed within a plurality of second gaps.
[0011] In one embodiment, each fourth light source is rectangular, and the length direction of each fourth light source is parallel to the second direction.
[0012] In one embodiment, there is a second gap between adjacent first light sources in each first light source row, and the second gaps of two adjacent first light source rows are staggered from each other along a second direction; each second light source is rectangular and includes a first portion and a second portion that are opposite to each other along its length direction; the length direction of each second light source is inclined relative to the first direction, such that the first portion corresponds to a second gap of an adjacent first light source row, and the second portion corresponds to a second gap of another adjacent first light source row.
[0013] In one embodiment, the geometric centers of the plurality of second light sources are aligned along a first direction.
[0014] In one embodiment, the length direction of each second light source forms a 60-degree angle with the first direction, and the length directions of two adjacent second light sources along the first direction intersect each other to form a 60-degree angle.
[0015] The beneficial effects of this application are as follows: Multiple first light sources on the backlight component are arranged in multiple rows of first light sources. Multiple second light sources are disposed within a first gap between adjacent rows of first light sources, and at least a portion of the second light sources is offset from the first light sources. This results in better uniformity of the distribution of these light sources on the backlight component. Almost all light-transmitting holes in the light-shielding layer can contain at least a portion of the first light source and / or at least a portion of the second light source, ensuring that almost all light-transmitting holes are illuminated, and that the brightness difference among these light-transmitting holes is small. Consequently, the brightness of the ceiling is more uniform, resulting in a better starry sky effect. Attached Figure Description

[0045] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0046] Figure 1 A vehicle 1 according to one embodiment of this application is schematically shown. Figure 1 As shown, vehicle 1 includes a roof 11. An optical trim 2 (hereinafter referred to as optical trim 2) for the vehicle is mounted on the surface of the roof 11 facing the passenger compartment (not shown in the figure).
[0047] like Figure 2 As shown, the optical element 2 includes a backlight element 201 and a light-shielding layer 202.
[0048] The backlight component 201 includes a substrate 203 and a plurality of light sources 204 disposed on the substrate 203. For example, the light sources 204 can be monochrome LEDs or color LEDs. These light sources 204 are arranged in a light source array.
[0049] A light-shielding layer 202 is disposed on the light-emitting surface of the backlight element 201, and the light-shielding layer 202 has multiple light-transmitting holes 205. For example, the light-shielding layer can be made of opaque materials such as fabric, suede, or genuine leather. In one embodiment, the light-transmitting holes 205 are generally circular with a diameter of approximately 1 mm. Of course, depending on the actual situation, the light-transmitting holes can also be other shapes and / or other sizes, which are not limited here. When these light sources 204 emit light, the light emitted by the light sources 204 can pass through the light-transmitting holes 205 and illuminate the passenger compartment of the vehicle. In this way, the occupants of the passenger compartment will see these light-transmitting holes 205 illuminated as bright spots, and the light-shielding layer 202 (or the ceiling 11) will present a starry sky effect. It should be understood that such optical trim can also be provided on other parts of the vehicle (such as doors), which will not be described in detail here.
[0050] The following describes the light source array formed by these light sources.
[0051] The light source array of the first embodiment
[0052] Figure 3 The light source array 21 of the first embodiment is shown schematically. (As shown) Figure 3 As shown, the light source array 21 of the first embodiment includes a plurality of first light sources 211 and a plurality of second light sources 212. In one embodiment, the first light sources 211 and the second light sources 212 have the same shape, both being generally rectangular. For example, the length of the first light source is approximately 0.5 mm and the width is approximately 0.16 mm, and the second light source is also approximately rectangular. Depending on the actual situation, the first light source can also be other shapes, such as squares or circles. In this case, the shape of the second light source can be different from that of the first light source; for example, the second light source can still be rectangular. Of course, the shape of the second light source can also be the same as that of the first light source. For simplicity, the following description uses the example of the first and second light sources being the same rectangle to illustrate the technical solution of this application.
[0053] Multiple first light sources 211 are arranged into multiple rows 213 along a first direction L1. The length direction of each first light source 211 is parallel to the first direction L1. A first gap 214 exists between adjacent rows 213. A second gap 215 exists between adjacent first light sources 211 within each row 213. Along a second direction L2 perpendicular to the first direction L1, these first light sources 211 are aligned with each other, and similarly, these second gaps 215 are also aligned with each other.
[0054] Taking a first gap 214 as an example, multiple second light sources 212 are disposed within the first gap 214, and each second light source 212 is completely offset from the first light source 211 along the second direction L2. For example, each second light source 212 is aligned with the second gap 215 along the second direction L2. In this way, these second light sources 212 effectively compensate for the gaps between these first light sources 211 (e.g., the first gap and the second gap), improving the uniformity of the distribution of these light sources in the light source array 21. As a result, almost all the light-transmitting holes 205 of the light-shielding layer 202 can contain at least a portion of the first light source 211 and / or at least a portion of the second light source 212 (i.e., some light-transmitting holes contain a first light source or a portion of the first light source, some light-transmitting holes contain a second light source or a portion of the second light source, and some light-transmitting holes contain both a portion of the first light source and a portion of the second light source), thereby achieving that almost all the light-transmitting holes 205 are lit, and the brightness difference of these light-transmitting holes is small. As a result, the brightness uniformity of the light source array 21 is good, the brightness uniformity of the ceiling is also good, and the starry sky effect is also good.
[0055] The length direction of the second light source 212 is parallel to the first direction L1 and aligned with each other along the first direction L1, thus arranging these second light sources 212 into a second light source row 216. The second light source row 216 is equidistant from the two adjacent first light source rows 213, further improving the uniformity of the distribution of these light sources in the light source array 21, thereby improving the brightness uniformity of the ceiling and the starry sky effect. Of course, depending on the actual situation, the second light source can also be set so that its length direction is not parallel to the first direction L1, for example, roughly along the second direction L2 or forming an acute angle with the first direction L1.
[0056] For example Figure 3 As shown, these second gaps 215 are aligned with each other along the second direction L2. Thus, each second light source 212 is equidistant from the four surrounding first light sources 211 (i.e., the four first light sources 211 are located at the four vertices of the rectangle, and the corresponding second light source 212 is located at the intersection of the diagonals of the rectangle), which also improves the uniformity of the light source distribution in the light source array 21 and helps to further improve the uniformity of the brightness of the light source array 21 (or the ceiling 11) and the starry sky effect.
[0057] The following describes the evaluation method for the brightness uniformity of the light source array in the first embodiment.
[0058] In one specific embodiment, the first light source 211 has a length of approximately 0.5 mm and a width of approximately 0.16 mm; the second light source 212 has the same shape as the first light source 211. The distance between the geometric centers of adjacent first light sources 211 along the first direction L1 is approximately 1.5 mm, and the distance between the geometric centers of adjacent first light sources 211 along the second direction L2 is approximately 0.8 mm. The geometric center of each second light source 212 is equidistant from the geometric centers of the four surrounding first light sources 211. Figure 4 As shown, 30 circles (indicating the positions of light-transmitting holes) are randomly arranged in the light source array 21. Each circle has a diameter of 1 mm. Table 1-1 shows the number of light sources contained in each circle.
[0059] Table 1-1
[0060] 0.4 0.9 0.8 0.4 0.8 1 1 0.2 0.6 1 0.6 0.3 0.7 0.8 0.8 0.8 0.8 0.9 0.3 0.95 0.7 0.3 0.7 0.9 1 0.7 0.7 1 0.7 0.7
[0061] Using the number of light sources contained in each of the 30 circles in Table 1-1 as a sample, the sample variance was calculated to be 0.055.
[0062] In another specific embodiment, the first light source 211 has a length of approximately 0.5 mm and a width of approximately 0.16 mm; the second light source 212 has the same shape as the first light source 211. The distance between the geometric centers of adjacent first light sources 211 along the first direction L1 is approximately 1.25 mm, and the distance between the geometric centers of adjacent first light sources 211 along the second direction L2 is approximately 0.64 mm. The geometric center of each second light source 212 is equidistant from the geometric centers of the four surrounding first light sources 211. Figure 4 As shown, 30 circles (indicating the positions of light-transmitting holes) are randomly arranged in the light source array 21. Each circle has a diameter of 1 mm. Table 1-2 shows the number of light sources contained in each circle.
[0063] Table 1-2
[0064] 1.2 1.1 1.1 1.2 1.1 1 1 1.1 0.9 1.1 1.1 1 0.4 1 0.8 0.4 1 0.7 1 0.4 0.9 1 0.4 0.9 0.4 1 0.8 0.4 1 0.8
[0065] Using the number of light sources contained in each of the 30 circles in Table 1-2 as a sample, the sample variance was calculated to be 0.07.
[0066] Figure 9 A schematic diagram of a light source array 24 in the prior art is shown. For example... Figure 9 As shown, in the light source array 24, multiple light sources 241 are aligned with each other along a first direction L1 and a second direction L2 that are perpendicular to each other.
[0067] The brightness uniformity of the light source array in the prior art is evaluated in the same way as the evaluation method for the brightness uniformity of the light source array in the first embodiment.
[0068] exist Figure 9 In the first direction L1, the distance between the geometric centers of adjacent light sources 241 is approximately 1.5 mm, and the distance between the geometric centers of adjacent light sources 241 along the second direction L2 is approximately 1 mm. Figure 10 As shown, 30 circles are randomly arranged in a prior art light source array. The diameter of each circle is 1 mm. Table A shows the number of light sources 241 contained in each circle. Using the number of light sources contained in each of the 30 circles in Table A as a sample, the sample variance is calculated to be 0.12.
[0069] Table A
[0070] 0.8 0.1 0.7 0.7 0.1 0.8 0.1 0 0.1 0.1 0 0.1 1 0.4 0.8 0.8 0.4 1 0.8 0.1 0.5 0.5 0.1 0.8 0.8 0.1 0.7 0.7 0.1 0.8
[0071] Compared to existing light source arrays, the sample variance derived from the light source array of the first embodiment of this application is smaller than that derived from existing light source arrays. Therefore, it can be concluded that the light source array of the first embodiment of this application has more uniform brightness, resulting in more uniform ceiling brightness and a better starry sky effect.
[0072] The light source array of the second embodiment
[0073] Figure 5 The light source array 22 of the second embodiment is schematically shown. (As shown) Figure 5 As shown, the light source array 22 in the second embodiment not only includes Figure 3 The plurality of first light sources 211 and the plurality of second light sources 212 shown also include a plurality of third light sources 223. These third light sources 223 are disposed within the first gap 214 and spaced apart from the second light sources 212.
[0074] For example Figure 5 As shown, multiple first light sources 211 are aligned with each other along the second direction L2, and a third light source 223 is disposed between two first light sources 211 aligned along the second direction L2. For example, each third light source 223 is a rectangle identical to the first light source 211, and the geometric center of each third light source 223 is aligned with the geometric centers of two adjacent first light sources 211 along the second direction L2. The geometric center here refers to the intersection of the diagonals of the rectangle. In this way, the third light source 223 effectively fills the gap between two adjacent first light sources 211 along the second direction L2, improves the uniformity of the distribution of these light sources in the light source array 22, and makes the brightness uniformity of the ceiling better, resulting in a better starry sky effect.
[0075] For example Figure 5 As shown, the geometric centers of the second light sources 212 are aligned with the geometric centers of the third light sources 223 along a first direction L1. In other words, the second light sources 212 and the third light sources 223 are arranged in a third light source row 221 along the first direction L1, and in each third light source row 221, the second light sources 212 and the third light sources 223 are arranged alternately. The third light source row 221 is also equidistant from any two adjacent first light source rows 213. This also improves the uniformity of the distribution of these light sources in the light source array 22, thereby improving the brightness uniformity of the ceiling and the starry sky effect.
[0076] For example Figure 5 As shown, the light source array 22 of the second embodiment also includes a plurality of fourth light sources 224. These fourth light sources 224 are respectively disposed within a plurality of second gaps 215 in each first light source row 213. For example, a second light source 212 is aligned with a corresponding fourth light source 224. This further improves the uniformity of the distribution of these light sources in the light source array 22, resulting in better brightness uniformity of the ceiling and a better starry sky effect.
[0077] In one embodiment, the length direction of each third light source 223 is parallel to the second direction L2. Each fourth light source 224 is also a rectangle identical to the first light source 211, and the length direction of each fourth light source 224 is also parallel to the second direction L2. Thus, as... Figure 5 As shown, the first light source 211, the fourth light source 224, the second light source 212, and the third light source 223, which are adjacent to each other, are distributed with rotational symmetry, which further improves the uniformity of the distribution of these light sources in the light source array 22. Almost all the light-transmitting holes 205 of the light-shielding layer 202 can contain at least a portion of the first light source 211 and / or at least a portion of the second light source 212 and / or at least a portion of the third light source 223 and / or at least a portion of the fourth light source 224, thus achieving that almost all the light-transmitting holes 205 are illuminated, and the brightness difference among these light-transmitting holes 205 is small. This further improves the brightness uniformity and starry sky effect of the ceiling.
[0078] It should be understood that, depending on the specific circumstances, the third light source can be of other shapes, such as a square or a circle. The same applies to the fourth light source.
[0079] The evaluation method for the brightness uniformity of the light source array in the second embodiment will now be described.
[0080] In one embodiment, the first light source 211 has a length of approximately 0.5 mm and a width of approximately 0.16 mm, and the first light source 211, the fourth light source 224, the second light source 212, and the third light source 223 have the same shape. Among the four rotationally symmetric light sources, the distance between the geometric centers of two adjacent light sources (e.g., the distance between the geometric center of the first light source and the geometric center of the adjacent fourth light source, and the distance between the geometric center of the first light source and the geometric center of the adjacent third light source) is approximately 0.66 mm.
[0081] like Figure 6 As shown, 30 circles (indicating the positions of light-transmitting holes) are randomly arranged in the light source array 22. Each circle has a diameter of 1 mm. Table 2 shows the number of light sources contained in each circle.
[0082] Table 2
[0083] 1 0.5 1 0.9 0.95 1 0.5 0 0.4 0.4 0.2 0.4 1 0.7 1 0.8 0.8 1 0.95 0.4 0.7 0.7 0.5 0.8 1 0.4 1 0.8 0.9 1
[0084] Using the number of light sources contained in each of the 30 circles in Table 2 as a sample, the sample variance was calculated to be 0.08. Compared with the light source arrays of the prior art, the sample variance obtained from the light source array of the second embodiment of this application is smaller than that obtained from the light source arrays of the prior art. Therefore, it can be concluded that the brightness of the light source array of the second embodiment of this application is more uniform, resulting in more uniform ceiling brightness and a better starry sky effect.
[0085] The light source array of the third embodiment
[0086] Figure 7 The light source array 23 of the third embodiment is shown schematically. (As shown) Figure 7As shown, the light source array 23 of the third embodiment includes a plurality of first light sources 211 and a plurality of second light sources 212 as described above.
[0087] Multiple first light sources 211 are arranged along a first direction L1 to form multiple rows 213 of first light sources, and a second gap 215 exists between adjacent first light sources 211 in each row 213. The second gaps 215 of two adjacent rows of first light sources 213 are staggered from each other along the second direction L. For example, the second gap in one row of first light sources is substantially aligned with the first light source in the adjacent row of first light sources.
[0088] There is a first gap 214 between adjacent rows 213 of first light sources along the second direction L2. These second light sources 212 are located within the first gap 214.
[0089] Each second light source 212 is rectangular in shape and includes a first portion 231 and a second portion 232. The first portion 231 and the second portion 232 are opposite to and connected to each other along the length direction of the second light source 212. Each second light source 212 is also configured such that its length direction is inclined relative to the first direction L1, so that the first portion 231 of the second light source 212 corresponds to a second gap 215 of an adjacent row of first light sources 213 (e.g., ...). Figure 7 (As shown by arrow A1 in the image), and the second portion 232 of the second light source 212 corresponds to a second gap 215 of an adjacent row 231 of the first light source (as shown by arrow A1 in the image). Figure 7 (As shown by arrow A2 in the diagram). Thus, not only are second light sources 212 disposed within the first gaps 214 between adjacent rows of first light sources 213, but each second gap 215 of the first light source row 213 is also surrounded by multiple light sources (e.g., two first light sources and multiple second light sources). In other words, the light source distribution in the light source array 23 is relatively uniform. Almost all the light-transmitting holes 205 of the light-shielding layer 202 can contain at least a portion of the first light source 211 and / or at least a portion of the second light source 212, thereby achieving that almost all the light-transmitting holes 205 are illuminated, and the brightness difference among these light-transmitting holes 205 is small. Therefore, the brightness uniformity of the light source array 21 is good, the brightness uniformity of the ceiling is also good, and the starry sky effect is also good.
[0090] For example Figure 7 As shown, the geometric centers of these second light sources 212 (i.e., the intersection of the diagonals of the rectangle) are aligned along the first direction L1. Thus, these second light sources 212 are arranged into a fourth light source row 234. The fourth light source row 234 is equidistant from both adjacent first light source rows 213, further improving the uniformity of light source distribution in the light source array 23, thereby improving the brightness uniformity of the ceiling and the starry sky effect.
[0091] The evaluation method for the brightness uniformity of the light source array in the third embodiment will now be described.
[0092] In one embodiment, the first light source 211 has a length of approximately 0.5 mm and a width of approximately 0.16 mm; the second light source 212 has the same shape as the first light source 211. The distance between the geometric centers of adjacent first light sources 211 in each row 213 of first light sources is approximately 1.32 mm. The distance between adjacent rows 213 of first light sources along the second direction L2 is approximately 1.65 mm. The length direction of each second light source 212 forms a 60-degree angle with the first direction L1, and the length directions of two adjacent second light sources 212 along the first direction L1 intersect each other to form a 60-degree angle. The distance between the geometric centers of two adjacent second light sources 212 along the first direction L1 is approximately 0.66 mm.
[0093] like Figure 8 As shown, 30 circles (indicating the positions of light-transmitting holes) are randomly arranged in the light source array 23. Each circle has a diameter of 1 mm. Table 3 shows the number of light sources contained in each circle.
[0094] Table 3
[0095] 0.4 1.1 1.2 0.4 1 1.1 1.4 1.5 1 1.1 1.5 1 1.3 1 1.5 1.5 1 1.2 1.5 1.1 1.3 1.3 1.1 1.3 1.1 1.4 1.3 1 1.4 1.3
[0096] Using the number of light sources contained in each of the 30 circles in Table 3 as a sample, the sample variance was calculated to be 0.075. Compared with the light source arrays of the prior art, the sample variance obtained from the light source array of the third embodiment of this application is smaller than that obtained from the light source arrays of the prior art. Therefore, it can be concluded that the brightness of the light source array of the third embodiment of this application is more uniform, resulting in more uniform ceiling brightness and a better starry sky effect.
