Description

Technical Field

[0001] This invention relates to the field of vehicle lighting technology, specifically to an ISD holographic signal light and a vehicle. Background Technology

[0002] With the development of automotive lighting and the changing needs of car buyers, headlight designs are becoming increasingly stylish and aesthetically pleasing. Beyond their functional and regulatory roles, headlight design is receiving more and more attention for its appearance, imaging capabilities, human-vehicle interaction, vehicle-to-vehicle interaction, dynamic design, and complexity. Current headlight imaging and avant-garde appearance designs primarily rely on ground projection and elaborate, complex headlight designs for imaging. However, ground projection produces a realistic image, which is easily obstructed, resulting in incomplete or visually impaired images. For example, placing a hand between the headlight and the projected pattern will partially or completely obscure the image. This also makes the image lack a sense of sophistication, virtuality, and spatial depth. In terms of appearance, headlight designs are often made more complex, with more components, narrower and flatter surfaces, or more curved designs. However, the headlight surface remains a large, monolithic design, lacking modularity and a futuristic, modular feel, failing to achieve a truly sophisticated aesthetic.

[0003] More importantly, the combination of imaging settings and appearance settings is a collection of the shortcomings of both settings, or even if the shortcomings of one setting are met and overcome, it is not compatible with overcoming the shortcomings of the other setting.

[0004] In addition, existing vehicle headlight imaging and appearance settings are often a single large component. When achieving dynamic effects, they lack a sense of multiple units, and the dynamic effects lack dynamism, appearing mechanical and lifeless. The imaging lacks a virtual feel, and the overall presentation cannot achieve a spatial presentation state that combines high-precision control with a sense of splicing and virtuality. Summary of the Invention

[0005] In view of the deficiencies in the prior art, the purpose of this invention is to provide an ISD holographic signal light and a vehicle.

[0006] According to the present invention, an ISD holographic signal light includes a circuit board, an anti-crossing light shield arranged in front of the circuit board, an external lens arranged in front of the anti-crossing light shield, a light source connected to the circuit board, and a hologram arranged between the external lens and the light source.

[0007] The anti-crosstalk shield is provided with multiple light-transmitting holes that are matched one-to-one with the light source, so that the light emitted by the light source can pass through the light-transmitting holes to form multiple ISD optical units at the front of the lamp body. When the light shines on the hologram, it can present a three-dimensional spatial holographic virtual image in the internal space of the lamp body.

[0008] Preferably, the light source is controlled in a time sequence so that the three-dimensional spatial holographic virtual image can present a three-dimensional dynamic spatial shape.

[0010] Preferably, the hologram is positioned closer to the external lens or attached to the external lens than the light source.

[0011] Preferably, the hologram includes multiple partial images, each of which is a composite grating design; or the hologram includes one image, with different holographic patterns set in different areas of the image.

[0012] Preferably, the holographic patterns in different regions can be integrated into one unit during operation by merging, splicing and / or overlapping, and when installing a whole hologram, the whole hologram can be attached to the outer lens or attached to the front end of the anti-cross-light shield.

[0013] Preferably, different holographic display effects can be presented by controlling some patterns in the hologram to work and some patterns to not work, wherein the switching between working and not working is achieved by turning the light source on and off.

[0014] Preferably, the circuit board is arranged behind the light source, which can be set as a monochromatic light source emitting colors other than white light.

[0015] Preferably, the external lens is made of PC or PMMA material.

[0016] Preferably, the steps of ISD holographic imaging are as follows:

[0017] S1: Received the design requested by the customer;

[0018] S2: Based on the pattern requested by the customer, the pattern is first broken down;

[0019] S3: Based on the split pattern, allocate and arrange it into each section of the ISD;

[0020] S4: Then complete the recording of the hologram, where each part of the hologram is responsible for recording a part of the image;

[0021] S5: Assemble the hologram into the ISD system;

[0022] S6: Illuminate the hologram in the ISD system to achieve ISD holographic 3D imaging.

[0023] A means of transportation according to the present invention includes the aforementioned ISD holographic signal light.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. This invention uses the ISD holographic signal light imaging system to achieve personalized appearance of multiple units, 3D stereoscopic effect and continuous appearance effect, with a sense of mystery. It also realizes a variety of highly flexible combination methods, and finally presents a variety of spatial visual 3D effects by splicing, combining and / or overlapping, etc., showing a high-end and high-quality car light appearance effect, realizing a holographic effect, which is an imaging effect similar to a virtual image that floats or exists in space within the car light. It has fewer parts, lower cost, smaller space, and smaller assembly tolerance chain.

[0058] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0059] This invention provides an ISD holographic signal light, comprising a circuit board 4, a crosstalk shield 3 disposed in front of the circuit board 4, an external lens 2 disposed in front of the crosstalk shield 3, a light source 5 connected to the circuit board 4, and a holographic light disposed between the external lens 2 and the light source 5. Figure 6 The outer lens 2 is preferably made of transparent materials such as PC or PMMA, mainly to protect the lamp. The circuit board 4 is preferably located directly behind the light source 5. The anti-crosslight shield 3 is densely covered with openings, and has multiple light-transmitting holes 31 that match the light source 5 one by one, so that the light emitted by the light source 5 can pass through the light-transmitting holes 31 to form multiple ISD optical units 9 at the front of the lamp body, and the light illuminates the hologram. Figure 6 This allows for the presentation of a three-dimensional holographic virtual image within the lamp body; the light emitted by light source 5 passes through the hologram. Figure 6 Light emitted from the outer lens 2, and the anti-crossing light shield 3 can effectively prevent light from crossing between each ISD optical unit.

[0060] ISD holography is a two-step lensless imaging method that uses the principle of "interference recording and diffraction reconstruction" to record the object light waves from a three-dimensional object onto a photosensitive material, called a hologram. The hologram is then illuminated as needed. Figure 6 This is a new imaging technology that reproduces the light waves of a previously recorded object. It is a three-dimensional imaging technology. The ISD pixel intelligent interactive signal light in the car headlights is composed of many pixelated units. ISD is an abbreviation for Intelligence Signal Display, and its Chinese name is intelligent interactive signal light. When different holographic elements are set in these units... Figure 6 This allows us to record different images, and then illuminate these holograms. Figure 6 This allows for the creation of 3D visual effects for animations and graphics in various styles defined by the client, including holographic effects. Figure 6 It records the three-dimensional information of the object, so it is done through holography. Figure 6 The resulting image is also a three-dimensional virtual image, and the imaging position is within the holographic field. Figure 6 Behind.

[0061] The production process of ISD holographic imaging is as follows: Upon receiving the pattern requested by the client, the pattern is first broken down according to the client's requirements. Then, the broken down pattern is allocated and arranged into various areas of the ISD to complete the holographic imaging. Figure 6 Records, holographic Figure 6 Each part is responsible for recording a portion of the image, assembling the hologram. Figure 6 In the ISD system, illuminate the hologram within the ISD system. Figure 6 To achieve ISD holographic three-dimensional imaging.

[0062] When assembling the ISD holographic signal light, the holographic... Figure 6 It can be placed anywhere between the external lens 2 and the light source 5, holographic Figure 6 Regardless of the placement position or distance between the device and the light source 5, the rendering effect remains consistent. Therefore, the setup is flexible, with high tolerance for positional errors, which is beneficial for manufacturing. Holographic Figure 6 The hologram is preferably positioned closer to or attached to the external lens 2. Figure 6 Corresponding one-to-one with the light source 5, it is placed at the exit position of the anti-light crosstalk shield 4. This setting can reduce the spatial size of the light illumination direction, which is conducive to miniaturization.

[0063] In one possible embodiment, holography Figure 6 It includes multiple partial images, each of which is a composite grating design; in another possible embodiment, holography... Figure 6 Including one, one hologram Figure 6 Different holographic patterns 61 are set in different areas. When working, the holographic patterns 61 in different areas can be merged, spliced, and overlapped into one whole and installed as a whole holographic sheet. Figure 6 At that time, the entire hologram could be displayed. Figure 6 It is attached to the outer lens 2 or attached to the front end of the anti-light-crossing shield 3 to embed the hologram. Figure 6 To reduce costs, a single hologram membrane can be used, eliminating the need for multiple hologram membranes; the hologram... Figure 6 Creating a single hologram would also help distinguish it from its multiple components. Figure 6 There is a risk of large relative positional tolerances between regions. However, due to the small relative positional tolerance chain between regions in this scheme, the spatial splicing effect is reliable.

[0064] In practical applications, the light source 5 is preferably a monochromatic light source, such as an LED. The emitted color of the light source 5 can be different, or it can be completely different. Each ISD optical unit 9 corresponds to a different, partially different, or completely identical emitted color of the light source 5. For example, some areas of the light source 5 emit deep red light, some areas emit ordinary red light, and some areas emit light red light. Alternatively, some areas may emit yellow light, while others emit blue light. However, it is important to note that the emitted color of the light source 5 cannot be white light; otherwise, interference cannot be generated, and a holographic effect cannot be achieved. The emitted color of the light source 5 can be a monochromatic light source or a combination of several monochromatic light sources. Furthermore, the circuit board 4 can be set to different colors, such as black, green, or white, which can be flexibly selected according to customer preferences.

[0065] This invention also provides a vehicle equipped with ISD holographic signal lights. The vehicle in this invention can be a gasoline-powered vehicle, an electric vehicle, etc. Cars using ISD holographic signal lights can enhance their premium feel and improve the overall appearance of their headlights.

[0066] Holography in this invention Figure 6 Whether it includes multiple parts or just one image, it is composed of multiple holographic patterns 61 combined, spliced, and overlapped into a whole. This allows for customization and modularity; simply select and configure different holographic patterns 61 to meet different appearance requirements, and change their combinations to achieve the desired effect, making it more intelligent. The combination methods can vary; for example, one mode may consist of only a portion of the hologram. Figure 6 Work, another part holographic Figure 6 It can remain inactive, achieving a spatial holographic display effect. When another mode is activated, it switches between the active and inactive holographic displays. Figure 6 Part of it, namely the holograms of other different regions. Figure 6 It starts working while the rest of the parts don't, achieving a second type of spatial holographic display effect. It has great flexibility and versatility, and these effects can be achieved simply by controlling the switching of the LEDs corresponding to the holographic patterns 61 in different areas.

[0067] like Figure 1 , Figure 3 As shown, the ISD holographic signal lamp 1 includes multiple independent ISD optical units 9. For a specific ISD optical unit 9, when the reconstructed illumination light wave 7 emitted by the light source 5 illuminates the holographic pattern 61, the three-dimensional object pattern information recorded on the holographic pattern 61 forms the first direct image 81. Similarly, other parts will simultaneously generate other direct images, such as the second direct image 82, the third direct image 83, the fourth direct image 84, and so on. Finally, the direct images of each part are combined to form a composite direct image 8, which is a three-dimensional image. The three-dimensional shape of the final composite direct image 8 can be designed flexibly according to requirements.

[0068] This invention can achieve a dynamic flowing water effect through splicing, and the light source 5 can be implemented through timing control, combined with... Figure 5-8 The following describes the ISD holographic virtual image 11 and its splicing method and effects:

[0069] Between the outer lens 2 and the circuit board 4, there is an ISD optical unit and a hologram. Figure 6The realized ISD holographic virtual image 11 can achieve dynamic splicing and presentation effects. The ISD holographic virtual image 11 includes multiple virtual image components, such as the first part 111, the second part 112, the third part 113, the fourth part 114, the fifth part 115, etc. During dynamic splicing, in the internal space of the headlight composed of the outer lens 2 and the circuit board 4, the multiple virtual image components of the ISD holographic virtual image 11 appear sequentially in a dynamic splicing manner and ultimately splice together to form various different spatial structures. Specifically, the first part 111 of the ISD holographic virtual image first presents a spatial holographic virtual image, located within the internal space of the headlight, presenting a three-dimensional and spatial effect. In this embodiment, the preferred first part 111 of the ISD holographic virtual image is a spatial cube. At the next time point, such as... Figure 6 As shown, the second part 112 of the ISD holographic virtual image presents a spatial holographic virtual image, located inside the headlight space and adjacent to the first part 111 of the ISD holographic virtual image. One side of the two is attached, realizing that the second part 112 of the ISD holographic virtual image is dynamically spliced ​​into the space of the first part 111 of the ISD holographic virtual image. The second part 112 of the ISD holographic virtual image also presents a three-dimensional and spatial effect. In this embodiment, it is also preferred to be a spatial cube, and the size is the same as that of the first part 111 of the ISD holographic virtual image. It should be noted that the size and spatial shape can be different in other embodiments.

[0070] Furthermore, at the next two time points, such as Figure 7 As shown, the third part 113 of the ISD holographic virtual image presents a spatial holographic virtual image, located inside the headlight space and adjacent to the second part 112 of the ISD holographic virtual image. Their surfaces are aligned, achieving a dynamic spatial splicing of the third part 113 and the second part 112. The fourth part 114 of the ISD holographic virtual image presents a spatial holographic virtual image, located inside the headlight space and adjacent to the third part 113. Their surfaces are aligned. The surfaces are fitted together, realizing that the fourth part 114 of the ISD holographic virtual image is dynamically stitched onto the third part 113 of the ISD holographic virtual image in a spatial dynamic stitching. The third part 113 and the fourth part 114 of the ISD holographic virtual image also present a three-dimensional and spatial effect. In this embodiment, it is also preferably a spatial cube. After the fourth part 114 of the ISD holographic virtual image is stitched together, the first part to the fourth part 114 of the ISD holographic virtual image are stitched together end to end, forming a rectangular body. At the next time point, as Figure 8As shown, the fifth part 115 of the ISD holographic virtual image presents a spatial holographic virtual image, located inside the headlight space and adjacent to the upper surface of the second part 112 of the ISD holographic virtual image. The two are attached to this surface, realizing that the fifth part 115 of the ISD holographic virtual image is dynamically spliced ​​onto the second part 112 of the ISD holographic virtual image in a dynamic spatial splicing. It can also be understood that after the splicing of the first part 111 to the fourth part 114 of the ISD holographic virtual image is completed, the fifth part 115 of the ISD holographic virtual image is dynamically spliced ​​onto the upper side of the rectangle formed by the splicing of the first four parts. The fifth part 115 of the ISD holographic virtual image also presents a three-dimensional and spatial effect. In this embodiment, it is also preferably a spatial cube, with the same size as any one of the first part 111 to the fourth part 114 of the ISD holographic virtual image. After the dynamic splicing of the five parts is completed, the spliced ​​spatial image presents another irregular spatial image that is different from the rectangle.

[0071] The five parts of the entire splicing process do not appear simultaneously or all at once. The first part 111 to the fifth part 115 of the ISD holographic virtual image are presented and assembled into a spatial volume in a dynamic and spliced ​​manner in sequence. It has both the three-dimensionality and sophistication of a spatial virtual image, as well as the splicing, dynamism and mystery of a Transformer-like structure.

[0072] Light source 5, through time-series control, enables the three-dimensional spatial holographic virtual image to present a dynamic three-dimensional spatial shape. The splicing of spatial ISD holographic virtual images offers high flexibility and dynamism. Benefiting from the combined advantages of the ISD and holographic designs of this patented ISD holographic signal light, the ISD holographic signal light achieves dynamic spatial splicing. The space has many components and various splicing methods. Besides the splicing order and method mentioned above, other splicing orders and methods are also possible. After completing the splicing of the first part 111 to the fifth part 115 of the ISD holographic virtual image, other parts can be spliced ​​to complete the second layer of the rectangular body or other spatial image splicing. The spatial shape of each component of the ISD holographic virtual image is not limited to a cube; it can also be a sphere, a triangle, or an irregular shape. The spliced ​​spatial shape, in addition to rectangular and regular geometric spatial bodies, can also be spliced ​​into spatial animal virtual images, spatial human virtual images, spatial plant virtual images, spatial natural object virtual images, etc. The splicing direction and process are not singular or limited, and can be designed according to requirements.

[0073] When the interior of the headlights uses a splicing method to create a dynamic spatial virtual image, it has a three-dimensional and sophisticated feel, and also includes dynamic effects. The design of the ISD holographic signal lights ensures high precision in boundary control of each component during the splicing process. With a large number of units, each unit is controlled by a separate ISD part and hologram, ensuring the formation of a high-quality spatial virtual image while guaranteeing a dynamic splicing effect.

[0074] Besides compositing and splicing, the spatial overlay effect can also be achieved by overlapping objects. This requires the original objects to be spatially misaligned, and then the spatial overlay effect is recorded during the recording process. The spatial overlay virtual image has a deeper sense of space and folds, and can also create visual effects of color and contrast in brightness and darkness of the spatial virtual image.
