Description

Technical Field

[0001] The present application relates to the field of automobile projection technology, and in particular to a novel automobile dynamic projection lamp and a vehicle. Background Art

[0002] Car dynamic projection light is an innovative car lighting device that projects light onto the ground or wall through specific technology to form dynamically changing patterns or texts, adding a unique visual effect and sense of technology to the vehicle.

[0003] Figure 1 Shows the structural diagram of the current small car projection products, such as Figure 1 As shown, the main structure of current automotive small projection products includes a light source, a collimating lens, an imaging film, an imaging lens group, and a bracket. The light emitted by the light source is concentrated and balanced by the collimating lens, and then passes through the imaging film. The patterned part of the imaging film is light-transmissive, while the other parts are light-blocking, thereby forming a patterned light and shadow on the receptor.

[0004] exist Figure 1 Based on the basic architecture shown, various automotive projection products have emerged. For example, static pattern projection products directly utilize the aforementioned structure, but these projection patterns are limited. Another example is dynamic film projection products that incorporate mechanical / motor motion to drive the film image to achieve image shearing. While dynamic projection is possible, the mechanical switching of the projection pattern requires the introduction of a motor or other mechanical transmission structure, which not only increases product size and energy consumption, but also increases costs and limits the image format. Another example is using a micro-light-emitting diode (MicroLED) array as the light source, and achieving pattern changes by alternating the illumination of the MicroLEDs. However, the current difficulty lies in balancing light and heat. Due to the small spacing and high density of the MicroLEDs, the heat generated by the MicroLEDs cannot be dissipated quickly, affecting luminous efficiency. This also increases product size and energy consumption, increases costs, and limits the image format. For another example, the outer lens can be set as a microlens array, and the image corresponding to each small lens in the microlens array can be projected at the same position. By superimposing and offsetting multiple microlenses, dynamic and 3D projection effects can be achieved. However, this method will limit the size of the product due to the size of the lens, and the limited lens partitioning will result in a small number of animation frames and overly simple projection. If the lens arrangement is increased, the number and volume of the product light sources will also need to be increased accordingly.

[0005] Therefore, there is an urgent need to provide a new type of automotive dynamic projection lamp, which not only can quickly switch the projection pattern, but also can reduce the size of the automotive dynamic projection lamp, and reduce energy consumption and cost. Utility Model Content

[0019] The first controller is configured to control the voltage difference between each pixel electrode and the common electrode based on the preset pattern, so as to control the state of the corresponding liquid crystal molecules and further control the state of the corresponding pixel unit.

[0020] Optionally, the dynamic imaging film includes a first electrode layer, a second electrode layer, and a liquid crystal layer located between the first electrode layer and the second electrode layer;

[0021] The liquid crystal layer includes liquid crystal molecules arranged in an array, the first electrode layer includes a plurality of first electrode lines arranged along a first direction, the first electrode lines extending along a second direction, the second electrode layer includes a plurality of second electrode lines arranged along the second direction, the second electrode lines extending along the first direction, the first direction and the second direction being perpendicular, the liquid crystal molecules corresponding to intersections of projections of the first electrode lines and the second electrode lines on the liquid crystal layer, and the liquid crystal molecules correspond one-to-one to the pixel units;

[0022] The first controller is configured to control the voltage of each of the first electrode lines based on the preset pattern, and to control the voltage of each of the second electrode lines, so as to control the state of each of the liquid crystal molecules, and further control the state of each of the pixel units.

[0023] A vehicle comprises the novel automotive dynamic projection lamp described in any one of the above items.

[0024] Compared with the existing technology, the above technical solution has the following advantages:

[0025] The novel automotive dynamic projection lamp provided in an embodiment of the present application includes a light source, a collimating lens, a dynamic imaging film, and an imaging lens arranged in sequence along the light path transmission direction, wherein the dynamic imaging film includes pixel units arranged in an array, each pixel unit having two states: light-transmitting and light-shielding; when the pixel unit is in the light-transmitting state, the pixel unit allows the light emitted by the light source that passes through the collimating lens to pass through, and then pass through the imaging lens; when the pixel unit is in the light-shielding state, the pixel unit prevents the light emitted by the light source that passes through the collimating lens from passing through; the novel automotive dynamic projection lamp also includes a first controller, which is electrically connected to the dynamic imaging film. The first controller is used to control the state of each pixel unit in the dynamic imaging film based on a preset pattern, so that each pixel unit in the dynamic imaging film in the light-transmitting state forms a preset pattern, or each pixel unit in the dynamic imaging film in the light-shielding state forms a preset pattern, so that the light emitted by the light source passes through the collimating lens, the dynamic imaging film, and the imaging lens in sequence, forming a projection pattern identical to the preset pattern.

[0026] It can be seen that the new automotive dynamic projection lamp provided by the embodiment of the present application can realize different film patterns and thus different projection patterns by pixelating the imaging film into a dynamic imaging film, and controlling the light transmission / shading state of each pixel unit in the dynamic imaging film through the first controller, and the projection pattern can be quickly switched, and the animation is more concise, with short delay and high efficiency, without causing mechanical problems; at the same time, the dynamic imaging film for pattern transformation is separated from the light source, and the pattern transformation of the dynamic imaging film generates almost no light and heat, thereby not affecting the optical efficiency of the light source; The dynamic imaging film can also be separated from the first controller. The dynamic imaging film is relatively small in size and can be adapted to a smaller installation space at the imaging end, while the first controller can be installed in a relatively large space through a wiring harness. In this way, the optical system of the new automotive dynamic projection lamp provided in the embodiment of the present application is similar to the basic static pattern projection system, which can greatly reduce the size of the automotive dynamic projection lamp and reduce the power consumption and cost of the automotive dynamic projection lamp. With the rapid development of electronic system integration, the size and energy consumption of the first controller can be continuously reduced, and the size and energy consumption of the new automotive dynamic projection lamp provided in the embodiment of the present application can be further reduced.

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0039] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0040] As described in the background technology section, there is an urgent need to provide a new type of automotive dynamic projection lamp, which can not only quickly switch the projection pattern but also reduce the size of the automotive dynamic projection lamp and reduce energy consumption and cost.

[0041] In view of this, the embodiment of the present application provides a new type of automotive dynamic projection lamp, Figure 2 FIG. 1 shows a structural diagram of a novel automotive dynamic projection lamp provided by an embodiment of the present application. Figure 2 As shown, the new automotive dynamic projection lamp includes a light source 101, a collimating lens 102, a dynamic imaging film 103, and an imaging lens 104, which are arranged in sequence along the light path transmission direction; the light emitted by the light source 101 is concentrated and balanced by the collimating lens 102, passes through the dynamic imaging film 103, and then passes through the imaging lens 104 to form a patterned light and shadow.

[0042] Among them, the dynamic imaging film 103 includes pixel units arranged in an array, and each pixel unit has two states: light-transmitting and light-shielding. When the pixel unit is in the light-transmitting state, the pixel unit allows the light emitted by the light source 101 through the collimating lens 102 to pass through, and then pass through the imaging lens 104; when the pixel unit is in the light-shielding state, the pixel unit prevents the light emitted by the light source 101 through the collimating lens 102 from passing through.

[0043] like Figure 2 As shown, the new automotive dynamic projection lamp provided in the embodiment of the present application also includes a first controller 105, which is electrically connected to the dynamic imaging film 103. The first controller 105 is used to control the state of each pixel unit in the dynamic imaging film 103 based on a preset pattern, so that the pixel units in the dynamic imaging film 103 that are in a light-transmitting state constitute a preset pattern, or the pixel units in the dynamic imaging film 103 that are in a light-shielding state constitute a preset pattern.

[0044] It is understandable that when the first controller 105 controls each pixel unit in the dynamic imaging film 103 to be in a light-transmitting state, such as Figure 3 As shown, the background of the dynamic imaging film 103 is a completely white field. Thus, the light emitted by the light source 101 passes through the collimating lens 102, passes through each pixel unit in the dynamic imaging film 103, and then passes through the imaging lens 104, thereby being projected as a completely white field. At this time, there is no pattern in the projection.

[0045] When the first controller 105 controls some pixel units in the dynamic imaging film 103 to be in a light-transmitting state and another part of the pixel units to be in a light-shielding state, optionally, as Figure 4 As shown, the first controller 105 can control the various pixel units in the dynamic imaging film 103 that are in a light-shielding state to form a preset pattern, so that the light emitted by the light source 101 passes through the collimating lens 102, passes through the various pixel units in the dynamic imaging film 103 that are in a light-transmitting state, and then passes through the imaging lens 104 to be projected as a background bright area, while the various pixel units in the dynamic imaging film that are in a light-shielding state are correspondingly projected as a dark area pattern; alternatively, the first controller 105 can also control the various pixel units in the dynamic imaging film 103 that are in a light-transmitting state to form a preset pattern, so that the light emitted by the light source 101 passes through the collimating lens 102, passes through the various pixel units in the dynamic imaging film 103 that are in a light-transmitting state, and then passes through the imaging lens 104 to be projected as a bright area pattern, while the various pixel units in the dynamic imaging film that are in a light-shielding state are correspondingly projected as a background dark area.

[0046] When the first controller 105 controls all pixel units in the dynamic imaging film 103 to be in a light-shielding state, the background of the dynamic imaging film 103 is a completely black field. In this way, the light emitted by the light source 101, after passing through the collimating lens 102, will not pass through the various pixel units in the dynamic imaging film 103, nor will it pass through the imaging lens 104, and is thus projected as a completely black field. At this time, no pattern is projected.

[0047] In an embodiment of the present application, the first controller 105 is electrically connected to the dynamic imaging film 103, that is, the first controller 105 can be directly electrically connected to the dynamic imaging film 103, or the first controller 105 can also be indirectly electrically connected to the dynamic imaging film 103, for example, the first controller 105 is electrically connected to the dynamic imaging film 103 through a wiring harness.

[0048] It can be seen that the new automotive dynamic projection lamp provided by the embodiment of the present application can realize different film patterns and thus different projection patterns by pixelating the imaging film into a dynamic imaging film 103, and controlling the light transmission / shading state of each pixel unit in the dynamic imaging film 103 through the first controller 105, and the projection pattern can be quickly switched, and the animation is more concise, with short delay and high efficiency, without causing mechanical problems; at the same time, the dynamic imaging film 103 for pattern transformation is separated from the light source 101, and the pattern transformation of the dynamic imaging film 103 generates almost no light and heat, thereby not affecting the optical efficiency of the light source 101; The transformed dynamic imaging film 103 can also be separated from the first controller 105. The dynamic imaging film 103 is relatively small in size and can be adapted to a smaller installation space at the imaging end, while the first controller 105 can be installed in a relatively large space through a wiring harness. In this way, the optical system of the new automotive dynamic projection lamp provided in the embodiment of the present application is similar to the basic static pattern projection system, which can greatly reduce the size of the automotive dynamic projection lamp and reduce the power consumption and cost of the automotive dynamic projection lamp. With the rapid development of electronic system integration, the size and energy consumption of the first controller 105 can be continuously reduced, and the size and energy consumption of the new automotive dynamic projection lamp provided in the embodiment of the present application can be further reduced.

[0049] It should be emphasized that since the first controller 105 controls the film pattern switching of the dynamic imaging film 103 to be electronic switching, the pattern switching speed is fast, the number of patterns can be set according to demand, the animation is more concise, the delay is short, and the efficiency is high.

[0050] Optionally, the first controller 105 may include a first port, through which the preset patterns of the first controller 105 may be updated. In other words, the preset patterns in the first controller 105 may be updated to accommodate different application scenarios. It is understood that the control program in the first controller 105 may also be changed and updated.

[0051] Optional, such as Figure 2 and Figure 5 As shown, the first controller 105 and the dynamic imaging film 103 can be electrically connected through the harness 106. In this way, the dynamic imaging film 103 that performs pattern transformation can be separated from the first controller 105. The dynamic imaging film 103 is small in size and can be adapted to a smaller installation space at the imaging end, while the first controller 105 can be installed in a larger space through the harness 106. In this way, the optical system of the novel automotive dynamic projection lamp provided by the embodiment of the present application (such as Figure 2 ) and basic static pattern projection systems (such as Figure 1That is, both controllers 105 and 106 are similar in that they include a light source, a collimating lens, an imaging film, and an imaging lens sequentially arranged along the light transmission direction, thereby greatly reducing the volume of the automotive dynamic projection lamp and reducing the power consumption and cost of the automotive dynamic projection lamp. With the rapid development of electronic system integration, the volume and energy consumption of the first controller 105 can be continuously reduced, and the volume and energy consumption of the novel automotive dynamic projection lamp provided in the embodiment of the present application can be further reduced.

[0052] Figure 6 FIG. 1 shows a structural diagram of another novel automotive dynamic projection lamp provided by an embodiment of the present application. Figure 6 As shown, the novel automotive dynamic projection lamp provided in the embodiment of the present application may further include a second controller 107 . The second controller 107 is electrically connected to the light source 101 , and is used to control the light source 101 to be turned on and off.

[0053] Optionally, the light source 101 includes a light emitting diode (LED) and a printed circuit board (PCB), the light emitting diode is soldered on the PCB, and the PCB is electrically connected to the second controller 107, so that the second controller 107 controls the turning on and off of the light emitting diode through the PCB.

[0054] In this embodiment, optionally, the first controller 105 controlling the dynamic imaging film 103 can be separately provided from the second controller 107 controlling the light source 101; another optional embodiment, such as Figure 6 As shown, the first controller 105 for controlling the dynamic imaging film 103 and the second controller 107 for controlling the light source 101 may also be the same controller, and the same controller is electrically connected to the dynamic imaging film 103 and the light source 101 respectively through a wiring harness.

[0055] Optional, such as Figure 2 and Figure 6 As shown, the novel automotive dynamic projection lamp provided in the embodiment of the present application may further include a heat sink 108 for dissipating heat from the light source 101. It is understood that since the dynamic imaging film 103 undergoing pattern change is separated from the light source 101, and the pattern change of the dynamic imaging film 103 generates almost no light or heat, it does not affect the optical efficiency of the light source 101. Furthermore, the addition of a light source does not increase the size or energy consumption of the projection lamp.

[0056] Optionally, an optical fiber is connected to the side of each pixel unit in the dynamic imaging film 103 facing away from the collimating lens 102, and the end of the optical fiber away from the pixel unit is connected to the imaging lens 104. In other words, the light projected by each pixel unit in the dynamic imaging film 103 is transmitted to the imaging lens 104 through the corresponding optical fiber. With this arrangement, on the one hand, the imaging lens 104 can be separated from the dynamic imaging film 103, so that the imaging lens 104 can be installed in a smaller installation space at the imaging end, while the optical components such as the dynamic imaging film 103, the collimating lens 102, and the light source 101 can be installed in other places with relatively larger spaces, allowing for greater freedom in design and installation. On the other hand, the optical fibers connected to the individual pixel units in the dynamic imaging film 103 can further converge the light transmitted from each pixel unit to the imaging lens 104, which helps to reduce the light transmission area of the imaging lens 104 and make the imaging lens 104 more compact.

[0057] Based on any of the above embodiments, it can be understood that the first controller 105 can change the material properties of the pixel units in the dynamic imaging film 103 through voltage control or current control, thereby changing the light transmittance properties of the pixel units in the dynamic imaging film 103.

[0058] Optionally, in some embodiments of the present application, such as Figure 7 As shown, the dynamic imaging film 103 includes a common electrode layer 10, an array electrode layer 20, and a liquid crystal layer 30 located between the common electrode layer 10 and the array electrode layer 20; the liquid crystal layer 30 includes liquid crystal molecules arranged in an array, the array electrode layer 20 includes pixel electrodes arranged in an array, the liquid crystal molecules correspond to the pixel electrodes one-to-one, and the liquid crystal molecules correspond to the pixel units one-to-one; the first controller 105 is used to control the voltage difference between each pixel electrode and the common electrode based on a preset pattern to control the state of the corresponding liquid crystal molecules, and then control the state of the corresponding pixel unit.

[0059] As we know, liquid crystal is a special substance between solid and liquid. It has both the fluidity of liquid and the optical properties of crystal. Liquid crystal molecules are arranged very regularly under normal conditions. When an electric field is applied to the liquid crystal, its molecular arrangement will change, causing the liquid crystal molecules to be in a light-transmitting or light-shielding state. Therefore, in this embodiment, the first controller 105 is used to control the voltage difference between each pixel electrode and the common electrode based on a preset pattern, that is, to control the electric field between each pixel electrode and the common electrode to control the state of the corresponding liquid crystal molecules, and then control the state of the corresponding pixel unit. When the liquid crystal molecules are in a light-transmitting state, the corresponding pixel unit is in a light-transmitting state; when the liquid crystal molecules are in a light-shielding state, the corresponding pixel unit is in a light-shielding state.

[0060] Alternatively, in some embodiments of the present application, Figure 8 As shown, the dynamic imaging film 103 includes a first electrode layer 40, a second electrode layer 50, and a liquid crystal layer 30 located between the first electrode layer 40 and the second electrode layer 50 (the liquid crystal layer 30 is located between the first electrode layer 40 and the second electrode layer 50). Figure 8 The liquid crystal layer 30 includes liquid crystal molecules arranged in an array. The first electrode layer 40 includes a plurality of first electrode lines arranged along a first direction X, and the first electrode lines extend along a second direction Y. The second electrode layer 50 includes a plurality of second electrode lines arranged along a second direction Y, and the second electrode lines extend along the first direction X. The first direction X and the second direction Y are perpendicular. The intersection of the projections of the first electrode lines on the liquid crystal layer 30 and the projections of the second electrode lines on the liquid crystal layer 30 corresponds to the liquid crystal molecules. The liquid crystal molecules correspond to the pixel units one-to-one. The first controller 105 is used to control the voltage of each first electrode line based on a preset pattern, and to control the voltage of each second electrode line, so as to control the state of each liquid crystal molecule, and thereby control the state of each pixel unit.

[0061] In this embodiment, the first controller 105 is used to control the voltage of each first electrode line based on a preset pattern, and to control the voltage of each second electrode line. This means that the electric field of each liquid crystal molecule is controlled, thereby controlling the state of the corresponding liquid crystal molecule and, in turn, the state of the corresponding pixel unit. When the liquid crystal molecule is in a light-transmitting state, the corresponding pixel unit is in a light-transmitting state; when the liquid crystal molecule is in a light-blocking state, the corresponding pixel unit is in a light-blocking state.

[0062] Alternatively, the dynamic imaging film 103 may be an electrochromic glass including a plurality of electrochromic elements. The first controller 105 controls the voltage applied to the electrodes at both ends of each electrochromic element based on a preset pattern, and regulates the state of each electrochromic element so that each electrochromic element is in a light-transmitting or light-shielding state. The electrochromic elements and pixel units correspond one to one; when the electrochromic element is in a light-transmitting state, the corresponding pixel unit is in a light-transmitting state; when the electrochromic element is in a light-shielding state, the corresponding pixel unit is in a light-shielding state.

[0063] Accordingly, the embodiment of the present application further provides a vehicle, including the novel automotive dynamic projection lamp provided by any of the above embodiments. Since the novel automotive dynamic projection lamp provided by the embodiment of the present application has been described in detail in the above embodiments, it will not be repeated here.
