Technical Field

[0001] The present application relates to the field of optics, and in particular to a projection device, a projection module and a vehicle. Background Art

[0002] According to the imaging principle, current projection lamps can be divided into three types: film lens type, MLA (micro lens array) type, and DLP type. Among them, MLA technology is a method based on optical microlenses and is widely used in imaging, display and lighting systems. It arranges multiple microlens units on the surface to form multiple channels to regulate light, thereby achieving efficient light distribution and precise control.

[0003] Specifically, the MLA module engraves patterns on the mask layer of each microlens. The light passes through the pattern of the microlens and is projected onto the ground through optical systems such as collimation and projection lenses to form a single image. Multiple single images are superimposed to form a projected image, thereby achieving the effect the user wants. Traditional MLA has a basically complete pattern in each microlens.

[0018] In some embodiments, the main light emitting direction of the light source component is toward the middle of the array surface, and the brightness of the light emitted by the light source component irradiating the middle area close to the light incident side of the projection device is greater than the brightness of the light irradiating the middle area away from the light incident side of the projection device;

[0051] In order to make the purpose, technical solution and advantages of the technical solution of the present application clearer, the technical solution of the embodiment of the present application will be clearly and completely described in conjunction with the drawings of the specific embodiments of the present application hereinafter. The same figure marks in the drawings represent the same parts. It should be noted that the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the described embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0052] Unless otherwise defined, the technical terms or scientific terms used herein shall have the usual meanings understood by persons of ordinary skill in the field to which this application belongs. The words "first", "second" and similar words used in the patent application specification and claims of this application do not indicate any order, quantity or importance, but are only used to distinguish different components. Similarly, words such as "one" or "one" do not necessarily indicate a quantity restriction. Words such as "include" or "comprise" mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

"Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0053] like Figure 1 In the MLA module, patterns are engraved on the mask layer of each microlens, and the light passes through the pattern of each microlens, and is projected onto the ground through an optical system such as a collimator and a projection lens to form a single image. Multiple single images are superimposed to form a projection image, thereby achieving the desired effect of the user, such as a projection lamp technology using MLA disclosed in patent CN213635296U. That is, each microlens of the traditional MLA contains a basically complete pattern, which is superimposed on the screen after being projected by the system to form a complete image. However, because the image projected by each channel is a complete image or covers the entire projection area of ​​the target, the image formed is relatively rigid, the prompt information is not prominent, and the interactive experience is poor; and the design of the scheme is monotonous and cannot meet the current diverse needs.

[0054] For this purpose, refer to Figure 2-Figure 4 , Fig.12 On the one hand, the present application provides a projection device 10, comprising a plurality of partial projection single channels 100 arranged in an array; the partial projection single channels 100 have a mask unit, and the mask unit of each partial projection single channel 100 has a partial image block 111 for light to pass through, and each partial image block 111 is a part of a preset overall pattern 1, and two or more partial image blocks 111 constitute the overall pattern 1, and each partial projection single channel 100 of the projection device 10 can respond to the light of the light source component 20 on the light incident side, and cooperate with the projection on the light emitting side to form an overall image 2 corresponding to the overall pattern 1.

[0055] Specifically, take the preset overall pattern 1 as an "arrow" as an example. The local tiles 111 in different local projection single channels 100 are respectively part of the preset overall pattern 1, that is, the overall pattern 1 is composed of at least two local tiles 111 (the composition form here can be a non-overlapping docking or a partially overlapping splicing), the shapes of different local tiles 111, and the positions of different local tiles 111 on the array surface of the projection device are different, and the number of local tiles 111 of the same shape and the distribution form on the array surface can be customized according to personalized needs, so that the intensity of light energy that can pass through different local tiles 111 can be freely and flexibly adjusted, so that the local single images formed by the local projection single channels 100 are superimposed to form the overall image 2 on the ground, which is easier to present the image effect of partition brightness change and brightness gradient, so as to emphasize the display information, increase interactivity, or increase the sense of technology and high-end feeling of projection.

[0056] It is worth noting that regarding the array arrangement of the present application, the array can be a matrix structure arranged in sequence in two or more directions, or a structure arranged in sequence in a single direction, both of which are within the protection scope of the present application and are not limited by the present application.

[0057] refer to Figure 5-Figure 10 In some embodiments, on the array surface of the projection device 10, the multiple local projection single channels 100 are divided into a first channel group 10a, ..., an nth channel group, where n≥2, and each channel group is used to form a local image segment (21a, 21b) on the light-emitting side, and the local image segment (21a, 21b) is a part of the overall image 2; wherein the first channel group 10a is arranged close to the middle of the array surface of the projection device 10, and in a direction gradually away from the middle of the array surface, the remaining channel groups are sequentially arranged on the outside of the first channel group 10a.

[0058] Specifically, taking n=2 as an example, the local projection single channel 100 is divided into a first channel group 10a and a second channel group 10b. On the array surface of the projection device 10, the second channel group 10b is arranged at the periphery of the first channel group 10a. Fig.12When the point-shaped light source component 20 is arranged on the light incident side of the projection device 10 and the projection on the array surface is located near the middle of the array surface, when the light emitted by the light source component 20 hits the projection device 10, the brightness of the area near the middle of the array surface is greater than the brightness of the area far from the middle of the array surface, and the light transmittance per unit area of ​​the area near the middle of the array surface is relatively large. Therefore, when the number of local projection single channels 100 in two adjacent channel groups is almost the same, the intensity of the light beam passing through the first channel group 10a is greater than the intensity of the light beam passing through the second channel group 10b, that is, the brightness of the first local image segment 21a (arrow head segment) projected by the first channel group 10a is greater than the brightness of the second local image segment 21b (arrow tail segment) projected by the second channel group 10b; the light transmittance per unit area of ​​the area far from the middle of the array surface is relatively small, which is conducive to presenting the second local image segment 21b with weak light, and finally a projection effect of the overall image 2 with gradually changing brightness can be presented on the ground.

[0059] Preferably, in a direction gradually away from the middle of the array surface, each channel group can be arranged side by side on the array surface in sequence. The side by side arrangement has a simple layout design and is easy to typeset and print during production, and is also convenient for flexible change and adjustment of the shape of the local blocks 111 of each channel group.

[0060] refer to Figure 6-Figure 8 In some embodiments, each local image block 111 included in a single channel group contains a pre-enhancement element A (the tip of the arrow, the position where the maximum projection brightness is expected);

[0061] The channel group includes a channel capable of allowing light to pass through and the projection substantially covers Figure 8 The local image block I111a of the first local image segment 21a and the local image block II111b of the projection covering part of the first local image segment 21a, the local image block I111a is close to the center of the array surface and is arranged in a cross shape.

[0062] Specifically, the projection of the local image block I111a basically covers the entire first local image segment 21a. When it is set near the center of the array surface and arranged in a cross shape, more light passes through and the brightness is kept uniform in the two intersecting directions of the "cross", which can ensure that the entire first local image segment 21a projected to the ground has a sufficiently large and uniform brightness; and each local image block 111 included in a single channel group contains a "pre-enhancement element A", so that the front end sharp corner position corresponding to the "pre-enhancement element A" on the projected first local image segment 21a shows a larger and more prominent brightness, and the first local image segment 21a presents a more prominent gradient display effect, and the brightness from the tip of the arrow to the tail of the arrow is weakened in multiple levels and levels.

[0063] By implementing the solution of this embodiment, the overall image 2 can be split into multiple gradient display levels according to design requirements, and the above method can be used to achieve a multi-level gradual increase or decrease effect, or to achieve an emphasis display effect, so that the pattern prompt information is clearer, the pattern design can be richer, and provide users with a better perceptual interactive experience.

[0064] In other embodiments, in the projection device, some local image blocks 111 contain pre-enhancement elements A, and the number of local image blocks 111 containing pre-enhancement elements A is greater than the number of local image blocks 111 not containing pre-enhancement elements A. In this embodiment, in the projection device, by increasing the number of local image blocks 111 containing pre-enhancement elements A, the light flux passing through the pre-enhancement elements A can also be increased, thereby making the position corresponding to the "pre-enhancement elements A" in the overall image 2 of the ground show greater and more prominent brightness, presenting a gradient highlighting display effect.

[0065] In other embodiments, on the array surface of the projection device 10, the multiple local projection single channels 100 are divided into a first channel group 10a, ..., an nth channel group, n≥2, and each channel group is used to form a local image segment (21a, 21b) on the light output side, and the local image segment (21a, 21b) is a part of the overall image 2; wherein, the number of local projection single channels 100 in at least one channel group is greater than the number of local projection single channels 100 in the remaining channel groups.

[0066] Specifically, in this embodiment, by increasing the number of local projection single channels 100 in the channel group, the light flux passing through the channel group can be increased, so that the local image segment presented by the channel group on the ground shows a larger and more prominent brightness, and the overall gradient display effect is presented. This setting is also suitable for when the light source component 20 is a large surface light source facing the projection device 10 or the brightness of each part projected onto the light incident surface of the projection device 10 is basically the same.

[0067] refer to Fig.11 , in some embodiments, it also includes an overall projection single channel 200, the mask unit of the overall projection single channel 200 has an overall block for light to pass through, and is configured to respond to the light source component and project an overall single image. In this embodiment, taking the overall projection single channel and the local projection single channel as an example, the overall block in the overall projection single channel 200 is an overall pattern 1, which is used to project an overall single image; by adding the overall projection single channel 200, the brightness of the overall image 2 projected onto the ground can be enhanced, and even if part of the local projection single channel 100 is covered, part of the overall projection single channel 200 can still transmit light and form an image. The overall projection single channel and the local projection single channel may not be arranged on the same array surface, and there is no limitation here.

[0068] refer to Figure 12-13 In some embodiments, the local projection single channel 100 includes:

[0069] A focusing microlens 120, disposed on the light incident side of the mask unit, for focusing light entering through the light incident side and directing it into the local image block 111; and / or,

[0070] The projection microlens 130 is disposed on the light-emitting side of the mask unit and is used to project a light pattern toward the light-emitting side.

[0071] After being shaped and dimmed by the focusing micro-lens 120 and / or the projection micro-lens 130, it is helpful to converge the light, making the projected image clearer and brighter.

[0072] refer to Figure 2-Figure 4 , Fig.12 In one aspect, the present application provides a projection module configured to project an overall image 2, including:

[0073] The light source component 20 is disposed on the light incident side of the partial projection single channel 100 and is configured to emit light to activate each partial projection single channel 100 and present an overall image 2 on the light exit side of the projection device 10;

[0074] The projection device 10 includes a plurality of local projection single channels 100 arranged in an array, each of the local projection single channels 100 being configured to project a local single image on the light-emitting side, each of the local single images being a part of the overall image 2 and being basically within the range of the overall image 2 (part of the local single image may be outside the range of the overall image due to unevenness of the projection surface or errors); wherein two or more local single images constitute the overall image 2.

[0075] Specifically, as mentioned above, different local projection single channels 100 respectively have local blocks 111 for light to pass through, and respectively project a local single image on the light-emitting side. Each of the local single images is a part of the overall image 2 and is basically within the range of the overall image 2. The overall image 2 is composed of two or more local single images. The projection shapes of different local projection single channels 100 and the positions of different local projection single channels 100 on the array surface are different, and the number of local projection single channels 100 with the same projection shape and the distribution form on the array surface can be customized according to personalized needs, so that the light energy intensity passed by the local projection single channels 100 with different projection shapes can be freely adjusted. The overall image 2 finally projected and superimposed on the ground can easily present the image effect of partitioned brightness changes and brightness gradients, thereby emphasizing the display, enhancing interactivity, or increasing the sense of technology and high-end feeling of the projection.

[0076] refer to Figure 5-Figure 10 , Fig.12 , in some embodiments,

[0077] The main light emitting direction of the light source component 20 is toward the middle of the array surface, and the brightness of the light emitted by the light source component 20 irradiating the middle area of ​​the light incident side close to the projection device 10 is greater than the brightness of the light irradiating the middle area of ​​the light incident side far from the projection device 10;

[0078] On the array surface of the projection device 10, the multiple local projection single channels 100 are divided into a first channel group 10a, ..., an nth channel group arranged in sequence, where n≥2, and each channel group is used to form a local image segment (21a, 21b) on the light-emitting side, and the local image segment (21a, 21b) is a part of the overall image 2; wherein the first channel group 10a is arranged close to the middle of the array surface of the projection device 10, and in a direction gradually away from the middle of the array surface, the remaining channel groups are arranged in sequence on the outside of the first channel group 10a.

[0079] Specifically, taking n=2 as an example, the local projection single channel 100 is divided into a first channel group 10a and a second channel group 10b. On the array surface of the projection device 10, the second channel group 10b is arranged at the periphery of the first channel group 10a. When the light source component 20 is arranged on the light incident side of the projection device 10 and the main light output direction is toward the middle of the array surface, the brightness of the light distribution hitting the surface of the projection device 10 in the area close to the middle of the array surface is greater than the brightness of the area far from the middle of the array surface, and the light transmittance per unit area in the area close to the middle of the array surface is relatively large. Therefore, when the number of local projection single channels 100 in two adjacent channel groups is almost the same, the intensity of the light beam passing through the first channel group 10a is greater than the intensity of the light beam passing through the second channel group 10b, that is, the brightness of the first local image segment 21a (arrow head segment) projected by the first channel group 10a is greater than the brightness of the second local image segment 21b (arrow tail segment) projected by the second channel group 10b; the light transmittance per unit area in the area far from the middle of the array surface is relatively small, which is conducive to presenting the second local image segment 21b with weak light, and finally a projection effect with gradually changing brightness can be presented on the ground.

[0080] Preferably, in a direction gradually away from the middle of the array surface, each channel group can be arranged side by side on the array surface in sequence. The side by side arrangement has a simple layout design and is easy to typeset and print during production, and is also convenient for flexible change and adjustment of the shape of the local blocks 111 of each channel group.

[0081] refer to Figure 6-Figure 8 In some embodiments, the local image blocks 111 of each local projection single channel 100 included in a single channel group all contain pre-enhancement elements A (the front end of the arrow is the sharp corner, the position where the maximum projection brightness is expected);

[0082] The channel group includes a channel capable of allowing light to pass through and the projection substantially covers Figure 8The local image block I111a of the first local image segment 21a and the local image block II111b of the projection covering part of the first local image segment 21a, the local image block I111a is close to the center of the array surface and is arranged in a cross shape.

[0083] Specifically, the projection of the local image block I111a basically covers the entire first local image segment 21a. When it is set near the center of the array surface and arranged in a cross shape, more light passes through and the brightness is kept uniform in the two intersecting directions of the "cross", which can ensure that the entire first local image segment 21a projected to the ground has a sufficiently large and uniform brightness; and each local image block 111 included in a single channel group contains a "pre-enhancement element A", so that the front end sharp corner position corresponding to the "pre-enhancement element A" on the projected first local image segment 21a shows a larger and more prominent brightness, and the first local image segment 21a presents a more prominent gradient display effect, and the brightness from the tip of the arrow to the tail of the arrow is weakened in multiple levels and levels.

[0084] By implementing the solution of this embodiment, the overall image 2 can be split into multiple gradient display levels according to design requirements, and the above method can be used to achieve a multi-level gradual increase or decrease effect, or to achieve an emphasis display effect, so that the pattern prompt information is clearer, the pattern design can be richer, and provide users with a better perceptual interactive experience.

[0085] In other embodiments, on the array surface of the projection device 10, the multiple local projection single channels 100 are divided into a first channel group 10a, ..., an nth channel group, n≥2, and each channel group is used to form a local image segment (21a, 21b) on the light output side, and the local image segment (21a, 21b) is a part of the overall image 2; wherein, the number of local projection single channels 100 in at least one channel group is greater than the number of local projection single channels 100 in the remaining channel groups.

[0086] Specifically, in this embodiment, by increasing the number of local projection single channels 100 in the channel group, the light flux passing through the channel group can be increased, so that the local image segments (21a, 21b) presented by the channel group on the ground show greater and more prominent brightness, and the overall gradient display effect is presented. This setting is also suitable for the case where the light source component 20 is a large surface light source facing the projection device 10 or the brightness of each part projected onto the light incident surface of the projection device 10 is basically the same.

[0087] refer to Fig.11, in some embodiments, it also includes an overall projection single channel 200, the mask unit of the overall projection single channel 200 has an overall block for light to pass through, and is configured to respond to the light source component and project an overall single image. In this embodiment, taking the overall projection single channel 200 and the local projection single channel 100 as an example of being arranged on the same array surface, the overall block in the overall projection single channel 200 is an overall pattern 1, which is used to project an overall single image; by adding the overall projection single channel 200, the brightness of the overall image 2 projected onto the ground can be enhanced, and even if part of the local projection single channel 100 is covered, part of the overall projection single channel 200 can still transmit light and form an image. The overall projection single channel and the local projection single channel may not be arranged on the same array surface, and there is no limitation here.

[0088] refer to Figure 14-15 In some embodiments, a single local image block 111 may further include a plurality of local image primitives (the local image blocks are in a dispersed form), and the plurality of local image primitives form a local image primitive group 111';

[0089] The overall pattern is in the form of an overall array (the overall array is a hollow pattern composed of multiple small triangular patterns, and the overall shape of the overall array is in the form of a ">>>" type), the arrangement form of multiple local image elements in the local image element group 111' is basically consistent with the array form of the overall array, and at least two groups of local image element groups 111' together constitute the overall array; and the multiple local projection single channels 100 are configured to respond to the light on the light incident side of the projection device, and project on the light exiting side to form an overall image array 2' corresponding to the overall array.

[0090] Specifically, taking the preset overall pattern 1 as "an overall pattern array composed of multiple small triangles" as an example, a single local projection single channel 100 has a local graphic element group 111': for example, the local graphic element group I 111a' is a main body array of multiple small triangles, the local graphic element group II 111b' is an array of edge portions of multiple small triangles, and the local graphic element group III 111c' is an array of another edge portion of multiple small triangles. The local graphic element group I 111a' and the local graphic element group II 111b' can form an overall pattern array (the composition form can be a non-overlapping docking or a partially overlapping splicing), and different local graphic elements The shapes of the groups 111' and the positions of different local image element groups 111' on the projection device array surface are different, and the number of local image element groups 111' of the same shape and the distribution form on the array surface can be customized according to personalized needs (for example, the number of local image element group I 111a' is designed to be six> the number of local image element group II 111b' is designed to be four> the number of local image element group III 111c' is designed to be two), so that the light energy intensity that can pass through different local image element groups 111' can be freely and flexibly designed and adjusted, so that the local single images formed by the projection of each local projection single channel 100 are superimposed to form an overall image array 2' on the ground, which appears as follows Fig.15 The partition brightness changes and three-dimensional image effects.

[0091] In some embodiments, the shape of local picture element group III111c' can be a part of local picture element group II111b', and the projection of local picture element group III111c' on the light-emitting side basically falls on a partial area of ​​the projection of local picture element group II111b', so that a small local segment corresponding to "local picture element group III111c'" on the triangular edge of the ground projection pattern shows a more prominent brightness effect, that is, the small local segment in the projection corresponding to local picture element group III111c' presents a more prominent layered display, and the pattern as a whole presents a three-dimensional effect with light and dark shadows on the edges.

[0092] It is worth noting that, in addition to the above-mentioned embodiments, the areas of the different local graphic element groups may not be the same, and the area ranges of different local graphic element groups may be in a relationship of inclusion and being included; the multiple local graphic elements within each local graphic element group may have the same or different areas, and the present application does not impose any restrictions on this.

[0093] In addition to the embodiments described above in the present application, in some other embodiments, the local block 111 may also be in other shapes or arrangements, which are not limited here.

[0094] Another aspect of the present application provides a vehicle, comprising any of the above-mentioned projection devices 10 and projection modules. The projection device 10 and projection module can be arranged at any position of the vehicle including but not limited to the front, rear, and side of the vehicle, and the vehicle includes but is not limited to automobiles, trains, and other transportation vehicles.

[0095] The exemplary implementation modes of the present application are described in detail above with reference to the preferred embodiments. However, it can be understood by those skilled in the art that, without departing from the concept of the present application, various modifications and variations can be made to the above-mentioned specific embodiments, and various technical features and structures proposed in the present application can be combined in various ways without exceeding the protection scope of the present application, which is determined by the attached claims.
