[0033] Please refer to Figure 1 The embodiment of the present application provides a lighting device, including: a light-emitting body array and a driving module. The light-emitting body array includes a plurality of light-emitting bodies 1 arranged in an array, the light-emitting body 1 having a plurality of light-emitting surfaces 1a, and a plurality of light-emitting units 10 are arranged on at least part of the light-emitting surfaces 1a of each light-emitting body 1. The driving module independently controls each light-emitting unit 10, and the light-emitting units 10 on the plurality of light-emitting bodies 1 are turned on and off to form a three-dimensional pattern in space.
[0034] A plurality of luminous bodies 1 are arranged in an array to form a luminous body array and can be fixed on a mounting bracket 2; the luminous body 1 is a three-dimensional luminous structure having a plurality of luminous surfaces 1a, and the luminous surfaces 1a of the luminous body 1 can be used for emitting light from the luminous unit 10. The luminous body 1 can be made of opaque or translucent material.
[0035] exist Figure 1 In the example, the light-emitting body 1 is a rectangular column with six faces. In some embodiments, although the light-emitting body 1 has six faces, only the four side faces are light-emitting faces 1a, and the top and bottom faces are not light-emitting faces 1a. Multiple light-emitting units 10 can be arranged on the four light-emitting faces 1a. The present application is not limited to this. In some variations, multiple faces of the light-emitting body 1 can be light-emitting faces.
[0036] The light-emitting body 1 of the present application may also be in other shapes, as long as it is a polyhedron with multiple side faces as the light-emitting surface 1a. For example, the light-emitting body 1 may also be a cone, etc. Light-emitting bodies 1 of different shapes can form different lighting effects to adapt to different application scenarios.
[0037] A plurality of light-emitting units 10 are arranged on part of the light-emitting surface 1a or the entire light-emitting surface 1a of the light-emitting body 1. The light-emitting units 10 are used to emit light independently after being powered on and receiving a light signal. The light-emitting units 10 may have regular shapes such as triangles, quadrilaterals, circles, or other irregular shapes. Each light-emitting unit 10 may include light-emitting chips arranged in an array. Figure 3 As shown, the light-emitting chips of the same light-emitting unit 10 are turned on and off at the same time to emit light. In some variations, the light-emitting chips of the same light-emitting unit 10 can also be controlled separately so that the same light-emitting unit 10 can emit light to form different patterns.
[0038] The lighting of the light-emitting unit 10 can be realized by controlling the driving module. The driving module is connected to each light-emitting unit 10 to control each light-emitting unit 10 to emit light independently.
[0039] Among them, the driving module can be set in the mounting bracket 2, and the driving module can include a driving chip and a power supply. The power supply is connected to the driving chip and is used to supply power to the driving chip. Multiple channels are formed on the driving chip to correspond to different light-emitting units 10, and the lighting of each light-emitting unit 10 is controlled through the channels of the driving chip.
[0040] In some specific embodiments, a driver chip can form multiple channels, each of which can control a light-emitting unit 10 to achieve pattern display of each light-emitting unit 10. All light-emitting units 10 on the same light-emitting body 1 can be controlled by all channels on a driver chip, or by channels of different driver chips, depending on whether the number of light-emitting units 10 on the light-emitting body 1 matches the number of channels of the driver chip.
[0041] In order to ensure that each channel can control a corresponding light-emitting unit 10 to realize the display of a complete light-emitting pattern, in the present application, the total number of channels of all driving chips in the mounting bracket 2 is greater than or equal to the total number of light-emitting units 10 of all light-emitting bodies 1.
[0042] Specifically, by controlling the lighting of different light-emitting surfaces 1a of the same light-emitting body 1 and the lighting of different light-emitting units 10 of the same light-emitting surface 1a, the light-emitting body 1 can form different light-emitting effects.
[0043] By controlling the on and off of different light-emitting bodies 1 to form different three-dimensional patterns, the combination of light-emitting patterns formed by multiple light-emitting bodies 1 can be flexibly changed to make the formed three-dimensional patterns change in a variety of ways, so that observers can observe lighting effects with different spatial three-dimensional senses from different observation angles.
[0044] For example, Figure 2a to Figure 2d The different display states of the light emitting body 1 are shown in FIG. Figure 2a As shown, when none of the light-emitting units 10 on the light-emitting body 1 is lit, the light-emitting body 1 displays a static appearance image, and no light-emitting pattern is displayed on the light-emitting body 1 at this time.
[0045] Figure 2b In the process, all the light-emitting units 10 on the front light-emitting surface 1a of the light-emitting body 1 are lit, and the light-emitting body 1 displays Figure 2b The luminous pattern shown.
[0046] Figure 2c In the embodiment, all the light-emitting units 10 on the light-emitting surface 1a on the front and right sides of the light-emitting body 1 are lit, and the light-emitting body 1 displays Figure 2c The luminous pattern shown.
[0047] Figure 2d In the example, only all the light-emitting units 10 on the light-emitting surface 1a on the right side of the light-emitting body 1 are lit, and the light-emitting body 1 displays Figure 2d The luminous pattern shown.
[0048] Therefore, the lighting device provided in the embodiment of the present application is provided with a plurality of light-emitting units 10 on at least part of the light-emitting surface 1a of the light-emitting body 1, and then independently controls each light-emitting unit 10 to independently emit light along its light-emitting surface 1a through a driving module, so that each light-emitting body 1 independently displays a light-emitting pattern; the plurality of light-emitting bodies 1 are arranged in an array, and after the light-emitting patterns displayed by different light-emitting bodies 1 are combined, they can be combined in space to form a three-dimensional pattern, and the formed three-dimensional pattern can be observed with different three-dimensional display effects at different angles. Different from the existing display schemes of points, lines, and surfaces of vehicle lights, the present application can flexibly present different lighting effects with a spatial three-dimensional sense through the combination and transformation of the light-emitting patterns displayed by different light-emitting bodies 1, so as to enhance the competitiveness of the lighting device in the field of lamps.
[0049] Furthermore, within at least a portion of the visible viewing angle range of the light-emitting body array, the light-emitting body 1 is misaligned in the row direction and / or column direction of the light-emitting body array. Specifically, when the lighting device is actually used, a lamp housing is provided and installed inside and / or outside the vehicle, and the lamp housing and the mounting components together form a partial shielding, so that the overall lighting device has a visible viewing angle range.
[0050] Please refer to Figure 1As shown, the light emitters 1 in the light emitter array are arranged in multiple rows (in the D2 direction) and multiple columns (in the D1 direction). From the side view angle S, each light emitter 1 can be seen. In other words, Figure 1 The light-emitting body 1 in the side viewing angle S in the visible viewing angle range is staggered in the row direction and the column direction. When the light-emitting body array formed in this way is used as a lamp, the staggered light-emitting bodies 1 can enable the observer to see a three-dimensional pattern at the side viewing angle S.
[0051] Please refer to Figure 4 ,and Figure 1 The alignment array is arranged differently. Figure 4 The light-emitting bodies 1 in the second row are staggered with the light-emitting bodies 1 in the first row and the third row. From the viewing angles S1 and S2, the staggered light-emitting bodies 1 can be seen, so that the three-dimensional pattern can be conveniently seen from multiple viewing angles.
[0052] In addition, within at least a portion of the visible viewing angle range of the light-emitting body array, at least some of the light-emitting bodies 1 have at least two visible light-emitting surfaces.
[0053] Still refer to Figure 4 In the side view direction S1, it can be seen that each light emitting body 1 has two visible light emitting surfaces, namely the first light emitting surface 11 and the second light emitting surface 12, while the third light emitting surface 13 and the fourth light emitting surface 14 cannot be seen from the side view direction S. At least two visible light emitting surfaces can form a three-dimensional pattern together. More than two light emitting surfaces may be seen from other viewing angles, and a three-dimensional pattern may also be formed.
[0054] Through the above arrangement, in at least a part of the visible viewing angle range of the light-emitting body array, the light-emitting units 10 on each light-emitting surface of the plurality of light-emitting bodies 1 are turned on and off to form an overall three-dimensional pattern in combination in space.
[0055] As mentioned above, the lighting of the light-emitting units 10 on each light-emitting surface of a single light-emitting body 1 can form a light-emitting pattern of the light-emitting body. Multiple light-emitting bodies 1 are combined to form a three-dimensional pattern of the light-emitting body array. The three-dimensional pattern can be seen from the visible viewing angle to form a three-dimensional lighting effect.
[0056] like Figure 5 , Figure 7 As shown, the three-dimensional pattern seen within the visible viewing angle is jointly formed by the light-emitting units 10 on the light-emitting body array.
[0057] The three-dimensional patterns seen at different visual angles may be the same or different, which is based on the array arrangement position of each light-emitting body 1, whether the light-emitting units 10 on the light-emitting surface of each light-emitting body 1 are located in the same position, and whether the driving module controls the light-emitting units 10 at the same position to turn on and off.
[0058] In addition, as mentioned above Figure 4 , the light emitter 1 includes a first light emitting surface 11 and a second light emitting surface 12, the first light emitting surface 11 of each light emitter 1 in the light emitter array is arranged toward the first direction F1, and the second light emitting surface 12 of each light emitter 1 in the light emitter array is arranged toward the second direction F2;
[0059] In a first viewing angle range including a first direction F1 within the visible viewing angle range of the light-emitting body array, the light-emitting units 10 of the first light-emitting surfaces 11 of the plurality of light-emitting bodies 1 are turned on and off to form a first three-dimensional pattern in combination in space;
[0060] In the second viewing angle range including the second direction F2 within the visible viewing angle range of the light-emitting body array, the light-emitting units 10 of the second light-emitting surfaces 12 of the plurality of light-emitting bodies 1 are turned on and off to form a second three-dimensional pattern in combination in space.
[0061] Another Figure 5 For example, each light emitting body 1 has a first light emitting surface 11 in the first direction F1, and the light emitting unit 10 of the first light emitting surface 11 of each light emitting body 1 is controlled to be on and off to form a first three-dimensional pattern, which is seen from a first viewing angle range in the first direction F1. Figure 6 pattern.
[0062] Similarly, each light emitting body 1 has a second light emitting surface 12 in the second direction F2. By controlling the lighting of the light emitting unit 10 on the second light emitting surface 12 of each light emitting body 1, a second three-dimensional pattern can be formed. The second three-dimensional pattern is a pattern seen from a second viewing angle range in the second direction F2.
[0063] Please refer to Figure 7 and Figure 8 , Figure 7 In the first viewing angle range of the first direction F1, Figure 8 The first three-dimensional pattern. Figure 7 A second three-dimensional pattern is formed within a second viewing angle range of the second direction F2.
[0064] In some embodiments, the first 3D pattern and the second 3D pattern are independent patterns. For example, the first 3D pattern can be used to express first information, and the second 3D pattern can be used to express second information. In other embodiments, when moving from the first viewing angle range to the second viewing angle range, the first 3D pattern changes to the second 3D pattern to form a dynamic pattern.
[0065] Please refer to Figure 7The observer can see the first three-dimensional pattern in the first field of view in the first direction F1, and the second three-dimensional pattern in the second field of view in the second direction F2. However, when moving from the first field of view to the second field of view, a change from the first three-dimensional pattern to the second three-dimensional pattern will be formed, thereby forming a dynamic pattern such as a stop-motion animation, so as to enrich the types of observed three-dimensional patterns and the changing effects.
[0066] In addition to the first light-emitting surface 11 and the second light-emitting surface 12, the light-emitting body 1 may also include a third light-emitting surface 13. Figure 4 As shown, the third light emitting surface 13 of each light emitting body 1 in the light emitting body array is arranged toward the third direction F3;
[0067] In a third viewing angle range including the third direction F3 within the visible viewing angle range of the light-emitting body array, the lighting of the light-emitting units 10 of the third light-emitting surfaces 13 on the plurality of light-emitting bodies 1 can be combined in space to form a third three-dimensional pattern.
[0068] Similar to the first three-dimensional pattern and the second three-dimensional pattern, each light-emitting body 1 has a third light-emitting surface 13 in the third direction F3. The third three-dimensional pattern can be formed by controlling the lighting of the light-emitting unit 10 of the third light-emitting surface 13 of each light-emitting body 1.
[0069] Of course, a fourth light-emitting surface 14 may also be formed on the light-emitting body 1, and arranged in the same manner as above.
[0070] Referring to the above, the first light-emitting surface 11 and the third light-emitting surface 13 are arranged on opposite sides, and the first three-dimensional pattern and the third three-dimensional pattern formed are independent patterns. When moving from the first viewing angle range to the third viewing angle range, the first three-dimensional pattern changes to the third three-dimensional pattern to form a dynamic pattern.
[0071] The first stereoscopic pattern and the third stereoscopic pattern may be independent patterns used to express different information. When the second viewing angle range is between the first viewing angle range and the third viewing angle range, and the first stereoscopic pattern and the third stereoscopic pattern are independent and completely different patterns, the second stereoscopic pattern may be a buffer pattern when the first stereoscopic pattern is transformed into the third stereoscopic pattern, which is used to achieve the connection of different stereoscopic patterns when the viewing angle is converted. The buffer pattern can be obtained after processing the first stereoscopic pattern and the third stereoscopic pattern. For example, the brightness / pixel value of the light-emitting unit 10 of the second stereoscopic pattern at the same position is the average of the brightness / pixel values of the light-emitting units 10 of the third stereoscopic pattern and the first stereoscopic pattern at the same position, and the present application is not limited to this.
[0072] In another embodiment, in addition to the first light-emitting surface 11 and the second light-emitting surface 12, there may be a light-emitting surface that can be combined with the first light-emitting surface 11 to form a pattern. For example, the fourth light-emitting surface 14 included in the light-emitting body 1 is arranged so that the two light-emitting surfaces of the same light-emitting body 1 can be seen at the same time at certain viewing angles.
[0073] The fourth light-emitting surface 14 of each light-emitting body 1 in the light-emitting body array is arranged to face the fourth direction F4. Within the fourth viewing angle range of the visible viewing angle range of the light-emitting body array including the first direction F1 and the fourth direction F4, the lighting and extinguishing of the light-emitting units 10 of the first light-emitting surfaces 11 and the fourth light-emitting surfaces 14 on the multiple light-emitting bodies 1 are used to be combined together in space to form a fourth three-dimensional pattern.
[0074] This embodiment takes a three-dimensional pattern formed by combining two light-emitting surfaces on the same light-emitting body 1 as an example. Of course, there may also be a three-dimensional pattern formed by combining more than two light-emitting surfaces on the same light-emitting body 1.
[0075] Taking the three separate light-emitting surfaces of the light-emitting body 1 as an example, the three light-emitting surfaces can see their own three-dimensional patterns from their own orthographic projection viewing angle ranges, and when observed from different side viewing directions S, or when observed from different visual fields, combined lighting effect changes of different three-dimensional patterns can be observed.
[0076] It can also be a combination of two or more light-emitting surfaces on the same light-emitting body 1, so that two or more light-emitting surfaces of the same light-emitting body 1 can be seen at the same time, so that the three-dimensional pattern formed is richer and more varied.
[0077] When the above-mentioned lighting device is applied to a vehicle lamp, the embodiment of the present application further discloses a vehicle lamp, including any of the above-mentioned lighting devices, which are arranged inside or outside the vehicle. Specifically, the lighting device arranged inside the vehicle can be used as a vehicle luminous interior, such as an atmosphere light, etc. The lighting device arranged outside the vehicle can be used as a signal light, a grille light, or other vehicle lights, and the present application is not limited thereto.
[0078] The lighting device and vehicle lamps are not restricted by existing points, lines, and surfaces, and independent control of the light-emitting units 10 of the light-emitting array is achieved in a three-dimensional dimension, which can achieve a lighting display effect with a spatial three-dimensional sense under different viewing angles, provide a more flexible and creative three-dimensional lighting effect, and improve customer satisfaction.
[0079] The vehicle lamp has 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.
