In line with the development trend of the trend, automobile styling design is required to move towards digitalization, parameterization, and technological simplicity.
[0003] As an important part of the car, the requirements for innovative styling are also taken into account. Existing technical solutions have developed various signal light forms based on LED technology at the level of points, lines, and surfaces. However, the signal light technology based on the development and iteration of LED light sources for more than ten years can no longer fully meet the current creative styling design needs; for example, the current car light solutions are still insufficient in terms of the spatial three-dimensional sense of the lighting effect, and cannot provide users with a three-dimensional lighting experience.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0031] Please refer to Figure 1The embodiment of the present application provides a lighting device for use in a vehicle, comprising: a plurality of translucent light-emitting sheets 1 arranged on a mounting bracket 2 along a first direction F1, each translucent light-emitting sheet 1 being provided with a plurality of light-emitting units 10, each light-emitting unit 10 emitting light along the first direction F1; and a driving module, the driving module independently controlling each light-emitting unit 10 on each translucent light-emitting sheet 1, the light-emitting units 10 of the same translucent light-emitting sheet 1 turning on and off form a light-emitting pattern corresponding to the translucent light-emitting sheet 1, and the light-emitting patterns of the plurality of translucent light-emitting sheets 1 are spatially combined to form a three-dimensional pattern.
[0032] A plurality of light-transmitting light-emitting sheets 1 are fixedly mounted on a mounting bracket 2, and the mounting bracket 2 is used to provide support. The plurality of light-transmitting light-emitting sheets 1 are arranged along a first direction F1 on the mounting bracket 2. Specifically, the "arranged along the first direction F1" described in the present application is merely a general description of the arrangement direction of each light-transmitting light-emitting sheet 1. The arrangement of the plurality of light-transmitting light-emitting sheets 1 along the first direction F1 includes, but is not limited to, the plurality of light-transmitting light-emitting sheets 1 are aligned along the first direction F1, and the plurality of light-transmitting light-emitting sheets 1 are arranged along the first direction F1 but staggered by a certain distance. The present application can realize more variations, which will not be described in detail here.
[0033] A plurality of light-emitting units 10 emitting light along a first direction F1 are arranged in an array on each light-transmitting light-emitting sheet 1 .
[0034] The driving module is disposed in the mounting bracket 2, and the driving module is connected to the plurality of light-emitting units 10 respectively. The driving module can independently control each light-emitting unit 10 to emit light independently, and the on and off of each light-emitting unit 10 on the same light-transmitting light-emitting sheet 1 forms a light-emitting pattern corresponding to the light-transmitting light-emitting sheet 1. Since the driving module independently controls each light-emitting unit 10 on each light-transmitting light-emitting sheet 1, when different light-emitting units 10 of the same light-transmitting light-emitting sheet 1 are controlled to light up, the light-emitting patterns displayed by the light-transmitting light-emitting sheet 1 can be different.
[0035] Each light-transmitting luminous sheet 1 can independently display a luminous pattern. After the luminous patterns of multiple light-transmitting luminous sheets 1 are combined in space, a three-dimensional pattern of the lighting device can be formed in space, and a combined lighting effect with a spatial three-dimensional sense can be obtained. Furthermore, since multiple light-transmitting luminous sheets 1 are arranged in space, different spatial effects can be observed from different observation angles. The luminous patterns displayed by different light-transmitting luminous sheets 1 can be the same or different. By combining the luminous patterns of different light-transmitting luminous sheets 1, a flexible and changeable three-dimensional pattern can be formed to meet different lighting effect requirements.
[0036] The function of each of the above-mentioned light-transmitting luminous sheets 1 independently displaying a luminous pattern is achieved by controlling the lighting of each of the light-emitting units 10 on the light-transmitting luminous sheets 1 by a driving module.
[0037] Specifically, the driving module may generally include a driving chip and a power supply. The power supply is connected to the driving chip to supply power to the driving chip. A plurality of driving channels are formed on the driving chip to correspond to different light-emitting units 10 respectively. The driving module controls the on and off of the light-emitting unit 10 through the driving channels.
[0038] A plurality of driving channels may be formed on one driving chip, and each driving channel may control one light emitting unit 10 to realize pattern display of each light emitting unit 10 .
[0039] All the light-emitting units 10 on the same light-transmitting light-emitting sheet 1 can be controlled by all the driving channels on one driving chip, or by driving channels of different driving chips, depending on actual needs.
[0040] In addition, the light-transmitting light-emitting sheet 1 of the present application may be a thin sheet structure with a relatively thin thickness. The light-transmitting light-emitting sheet 1 may be made of a transparent material or a translucent material, so that the lit light-emitting units of the light-transmitting light-emitting sheet 1 arranged at the rear can be observed by the observer through the light-transmitting light-emitting sheet 1 arranged at the front. Therefore, combined with the independent control of the light-emitting units 10 by the driving module, the light-emitting patterns of the arranged light-transmitting light-emitting sheets 1 can be combined in space to form a three-dimensional pattern.
[0041] For example, in the present application Figure 1 In the embodiment, the mounting bracket 2 is a thin rectangular bracket, the light-transmitting luminous sheet 1 is a rectangular thin sheet, and three light-transmitting luminous sheets 1 are arranged side by side on the mounting bracket 2 along the front-to-back direction. At this time, the first direction F1 is Figure 1 The front-to-back direction.
[0042] Of course, in addition to this, the light-transmitting light-emitting sheet 1 and the mounting bracket 2 can also be other shapes. For example, the light-transmitting light-emitting sheet 1 can also be a triangular thin sheet, a circular thin sheet, etc. As long as the light-transmitting light-emitting sheet 1 is a thin sheet structure, the shape of the mounting bracket 2 is not specifically limited.
[0043] A plurality of light-transmitting luminous sheets 1 are arranged along a first direction F1 , and in the present application, the first direction F1 is a front-to-back direction; the light-transmitting luminous sheets 1 may also be arranged along other directions to adapt to different application scenarios.
[0044] In summary, in the lighting device provided by the embodiment of the present application, a plurality of translucent luminous sheets 1 are arranged along the first direction F1, and a plurality of luminous units 10 are arranged on each translucent luminous sheet 1. Each luminous unit 10 can independently emit light along the first direction F1 through the control of the driving module, thereby making the translucent luminous sheet 1 display a luminous pattern along the first direction F1. After the luminous patterns of different translucent luminous sheets 1 are combined in space, a three-dimensional pattern required by the lighting device can be formed. The three-dimensional pattern can form a lighting effect with a spatial three-dimensional sense in space. Furthermore, since the plurality of translucent luminous sheets 1 are arranged in space, different three-dimensional display effects of the lighting device can be observed at different angles. Different from the existing display schemes of points, lines, and surfaces of vehicle lights, the present application enables each translucent luminous sheet 1 to independently display a luminous pattern through the arrangement and setting of the translucent luminous sheets 1 and the independent control of each luminous unit 10 on the translucent luminous sheet 1. Through the combination and change of the luminous patterns displayed by different translucent luminous sheets 1, different three-dimensional lighting effects can be flexibly presented, providing new ideas for vehicle light design.
[0045] Specifically, each light-emitting unit 10 includes light-emitting chips arranged in an array. The driving module controls the light-emitting chips to realize the light-emitting unit 10 to emit light, and the light-emitting chips in the array on the same light-emitting unit 10 are lit and extinguished at the same time to realize the lighting of the light-emitting unit 10. The shape of the light-emitting chip array arrangement can form a pattern that the light-emitting unit 10 can display. When the arrangement of the light-emitting chips of the light-emitting unit 10 is different, the light-emitting unit 10 can display different patterns.
[0046] Furthermore, when the plurality of light-transmitting luminous sheets 1 have different arrangement states along the first direction F1 , different three-dimensional patterns are formed.
[0047] In one embodiment of the present application, a plurality of light-transmitting luminous sheets 1 are parallel to each other, for example Figure 1 In the example, three light-transmitting luminous sheets 1 are arranged parallel to each other along the first direction F1.
[0048] Furthermore, when arranged in parallel, there is also a gap between adjacent light-transmitting luminous sheets 1; in other words, multiple light-transmitting luminous sheets 1 are arranged in parallel and at intervals, and the intervals between the multiple light-transmitting luminous sheets 1 can be equal or unequal, and the interval setting can make the patterns of adjacent light-transmitting luminous sheets 1 have a distance, forming a spatial display effect. Furthermore, the interval setting can also better dissipate heat.
[0049] In some variations, at least some of the light-transmitting luminous sheets 1 may also form an angle greater than 0 degrees and less than 90 degrees, so as to achieve a display space sense different from that of the light-transmitting luminous sheets 1 arranged in parallel.
[0050] At least partially means that some of the light-transmitting light-emitting sheets 1 may be arranged at an angle greater than 0 degrees and less than 90 degrees, or all of the light-transmitting light-emitting sheets 1 may be arranged at an angle greater than 0 degrees and less than 90 degrees, which does not affect the overall layout of the light-transmitting light-emitting sheets 1 arranged along the first direction F1.
[0051] For example Figure 1 Among the three light-transmitting light-emitting sheets 1, two of them may be arranged at an acute angle, or three light-transmitting light-emitting sheets 1 may be arranged at an acute angle between two adjacent light-transmitting light-emitting sheets 1. In the embodiment where a plurality of light-transmitting light-emitting sheets 1 are arranged at an acute angle between two adjacent light-transmitting light-emitting sheets 1, the acute angle may be located on the same side of the plurality of light-transmitting light-emitting sheets 1, for example, in a fan-shaped arrangement; the acute angle may also be located on different sides of the plurality of light-transmitting light-emitting sheets 1, for example, between the first light-transmitting light-emitting sheet 1 and the second light-transmitting light-emitting sheet 1. Figure 1 The second light-transmitting luminous sheet 1 and the third light-transmitting luminous sheet 1 are arranged at an acute angle on the right side of Figure 1 In other words, the first light-transmitting luminous sheet 1 and the third light-transmitting luminous sheet 1 can be parallel to each other to reduce the thickness of the lighting device in space. The present application can realize more variations, which will not be described in detail here.
[0052] Due to different arrangement methods, the three-dimensional patterns formed by parallel arrangement and angled arrangement are different; the three-dimensional patterns formed by arranging some light-transmitting light-emitting sheets 1 at an angle and arranging all light-transmitting light-emitting sheets 1 at an angle are also different; when the angles are different during arrangement, the three-dimensional patterns formed are also different.
[0053] Still refer to Figure 1 The three light-transmitting light-emitting sheets 1 are arranged in parallel, and the sizes and arrangement positions of the three light-transmitting light-emitting sheets 1 are the same, so that the three light-transmitting light-emitting sheets 1 are aligned on each side in the first direction F1. In this way, the orthographic projections of the three light-transmitting light-emitting sheets 1 in the first direction F1 completely overlap.
[0054] In some other embodiments, the orthographic projections of the light-transmitting luminous sheets 1 in the first direction F1 intersect with each other.
[0055] Taking the parallel arrangement of the light-transmitting luminous sheets 1 as an example, when the light-transmitting luminous sheets 1 are arranged in parallel but have different sizes, for example Figure 2a The orthographic projection diagram of the light-transmitting light-emitting sheet 1 in the first direction F1 is shown. When the length of one light-transmitting light-emitting sheet 1a (the outermost large rectangular projection) along the second direction F2 perpendicular to the first direction F1 is longer than the length of the other light-transmitting light-emitting sheet 1b (the left rectangular projection), then in the second direction F2, the orthographic projection of the longer light-transmitting light-emitting sheet 1a is longer than the orthographic projection of the shorter light-transmitting light-emitting sheet 1b. At this time, the orthographic projection of the longer light-transmitting light-emitting sheet 1a intersects with the orthographic projections of the other light-transmitting light-emitting sheets 1b.
[0056] Or Figure 2b The orthographic projection diagram of the light-transmitting light-emitting sheet 1 in the first direction F1 is shown. Even if the three light-transmitting light-emitting sheets 1 are arranged in parallel and have the same size, but one of the light-transmitting light-emitting sheets 1a (solid line projection) and the other light-transmitting light-emitting sheet 1b (dotted line projection) are not arranged in alignment but staggered, the orthographic projections of the two light-transmitting light-emitting sheets 1 in the first direction F1 will intersect.
[0057] Alternatively, when the shapes of the light-transmitting light-emitting sheets 1 are different, for example, one of the light-transmitting light-emitting sheets 1 is a rectangular sheet and the other light-transmitting light-emitting sheet 1 is a triangular sheet, the orthographic projections of the two sheets in the first direction F1 also intersect.
[0058] It can be seen that when the orthographic projections of the light-transmitting luminous sheets 1 in the first direction F1 do not completely overlap, they all belong to the category of intersection.
[0059] As mentioned above, when the driving module controls different light-emitting units 10 of the same light-transmitting light-emitting sheet 1 to light up, the light-transmitting light-emitting sheet 1 can display different light-emitting patterns.
[0060] For example, when none of the light-emitting units 10 on the light-transmitting light-emitting sheet 1 is lit, Figure 3 The static appearance diagram of the light-transmitting luminous sheet 1 is shown, and the light-transmitting luminous sheet 1 is not emitting light at this time.
[0061] When all the light-emitting units 10 on the light-transmitting light-emitting sheet 1 are lit, Figure 4 The lighted appearance diagram of the light-transmitting light-emitting sheet 1 is shown. At this time, a light-emitting pattern is displayed on the light-transmitting light-emitting sheet 1 , and the light-emitting pattern is a combination of all the light-emitting units 10 on the light-transmitting light-emitting sheet 1 .
[0062] Only Figure 4 When some of the light-emitting units 10 on the light-transmitting light-emitting sheet 1 are lit, a pattern combination of some of the light-emitting units 10 can be formed, and the light-transmitting light-emitting sheet 1 and Figure 4 Different glowing patterns.
[0063] Based on this, when the light-emitting units 10 on the light-transmitting light-emitting sheet 1 are arranged in different arrays, the light-transmitting light-emitting sheet 1 can also form different light-emitting patterns. Figure 5 The light-emitting unit 10 on the light-transmitting light-emitting sheet 1 and Figure 4 The array arrangement of the light-emitting units 10 of the light-transmitting light-emitting sheet 1 is different, so the light-emitting patterns obtained when both are fully lit are obviously different.
[0064] Furthermore, the light-emitting units 10 of each light-transmitting light-emitting sheet 1 in the present application are arranged in the same array form.
[0065] For example, Figure 6The multiple light-emitting units 10 on the three light-transmitting light-emitting sheets 1 are arranged in an L-shaped array, and each light-transmitting light-emitting sheet 1 can display an L-shaped pattern when all are lit; or Figure 6 The multiple light-emitting units 10 on the three light-transmitting light-emitting sheets 1 are arranged in the same array. When the light-emitting units at the same position of the three light-transmitting light-emitting sheets 1 are lit to form an L-shaped pattern, the following can be formed: Figure 6 An L-shaped three-dimensional pattern is shown.
[0066] For example Figure 8 In the embodiment, the plurality of light-emitting units 10 of the three light-transmitting light-emitting sheets 1 are arranged in a straight line array, and each light-transmitting light-emitting sheet 1 can display a straight line pattern when all are lit; or Figure 8 The multiple light-emitting units 10 on the three light-transmitting light-emitting sheets 1 are arranged in the same array. When the light-emitting units at different positions of the three light-transmitting light-emitting sheets 1 are lit to form a straight line pattern, the following can be formed: Figure 8 The three-dimensional pattern shown.
[0067] Figure 6 Each of the light-transmitting luminous sheets 1 can display the same L-shaped pattern. When the three light-transmitting luminous sheets 1 are illuminated, the overlapping L-shaped pattern can be seen when viewed from the first direction F1. Figure 7 The L-shaped pattern, when viewed from the side, can be seen Figure 6 The L-shaped pattern of triple ghosting shown.
[0068] and Figure 8 The three light-transmitting luminous sheets 1 are located at different positions, and the three light-transmitting luminous sheets 1 can be seen when viewed from the front. Fig. 9 The three overlapping rows of straight lines are shaped like a line. When viewed from the side, you can see Figure 8 Three rows of inline pattern spaced apart as shown.
[0069] In some variations, the orthographic projections of at least some of the light-emitting units 10 of the light-transmitting light-emitting sheet 1 in the first direction F1 may overlap or intersect.
[0070] Refer to Figure 6 , Figure 6 The light-emitting units 10 of each light-transmitting light-emitting sheet 1 form the same L-shaped pattern at the same position, and the orthographic projections of the light-emitting units 10 of each light-transmitting light-emitting sheet 1 overlap in the first direction F1. Figure 7 An L-shaped pattern after overlapping is shown.
[0071] It should be noted that Figure 6 It can be seen that an L-shaped pattern is formed when all the light-emitting units 10 on the light-transmitting light-emitting sheet 1 are lit, and it can also be seen that an L-shaped pattern is formed when some of the light-emitting units 10 on the light-transmitting light-emitting sheet 1 are lit.
[0072] The situation where the orthographic projections of the light-emitting units 10 of the light-transmitting light-emitting sheet 1 intersect in the first direction F1 can be referred to in the above configuration and will not be described in detail.
[0073] On the other hand, the driving module can also light up some of the light-emitting units 10 so that the orthographic projections of the light-emitting patterns of the light-transmitting light-emitting sheets 1 in the first direction F1 do not overlap.
[0074] Again Figure 8 For example, Figure 8 It can also be considered that all or part of the light-emitting units 10 on the light-transmitting light-emitting sheet 1 are lit to form a straight line pattern. When part of the light-emitting units 10 on the light-transmitting light-emitting sheet 1 is lit to display a straight line pattern, since the straight line patterns of the three light-transmitting light-emitting sheets 1 are located at different positions in the first direction F1, the orthographic projection on the first direction F1 forms Fig. 9 The three rows shown are arranged in a straight line pattern, that is, the orthographic projections do not overlap.
[0075] Specifically, by controlling the on and off of the light-emitting units 10 on each light-transmitting light-emitting sheet 1, the light-emitting patterns of each light-transmitting light-emitting sheet 1 can be made the same, so as to display the three-dimensional effect of the light-emitting pattern in space. In some variations, by controlling the on and off of the light-emitting units 10 on each light-transmitting light-emitting sheet 1, the light-emitting patterns of each light-transmitting light-emitting sheet 1 can be sub-patterns of the same pattern in different spaces, so as to display the three-dimensional effect of the pattern in space. For example, the head of a tiger can be formed on the frontmost light-transmitting light-emitting sheet 1, the body of a tiger can be formed on the middle light-transmitting light-emitting sheet 1, and the tail of a tiger can be formed on the last light-transmitting light-emitting sheet 1, so that the three-dimensional pattern of the tiger can be shown in space. The above embodiments are only schematic, and the light-emitting patterns displayed by the light-transmitting light-emitting sheets 1 at different positions can be refined according to the specific patterns and display effects. Furthermore, in combination with different observation angles, richer dynamic effects of three-dimensional patterns can also be achieved. The present application can achieve more variations, which will not be repeated here.
[0076] Through the different arrangements of the light-transmitting luminous sheets 1 and the different arrangements of the light-emitting units 10, the three-dimensional pattern formed by the combination can be varied to adapt to different occasions, giving users a variety of choices and experiences.
[0077] Based on this, an embodiment of the present application further discloses a vehicle, comprising a lighting device as described above, wherein the lighting device is arranged inside or outside the vehicle.
[0078] The lighting device and the vehicle achieve a three-dimensional headlight shape with a spatial sense in the three-dimensional dimension, providing more flexible and creative lighting effects to enhance customer satisfaction.
[0079] The vehicle comprises the same structure and beneficial effects as the lighting device in the aforementioned embodiment. The structure and beneficial effects of the lighting device have been described in detail in the aforementioned embodiment and will not be repeated here.
[0080] The above description is only an embodiment of the present application and is not intended to limit the protection scope of the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
