Description

Technical Field

[0001] This application relates to the field of projection lamp technology, and in particular to an ambient image projection device. Background Technology

[0002] Ambient starry sky projection is a projection method that projects romantic astronomical and natural scenes onto walls and ceilings using a projection device. This projection method can transform a home into a room filled with stars, the Milky Way, and natural scenes, creating a comfortable, quiet, romantic, and relaxing space. Ambient lights are lights that can project patterns onto walls, floors, and screens. Ambient lights are commonly used in theaters, studios, bars, discos, and other stage entertainment settings. They can project monochrome or multi-colored patterns, such as water ripples, starry skies, or various lines, creating a warm and romantic immersive scene.

[0003] With continuous social progress and development, people's living standards have been constantly improving, and ambient lighting has gradually entered thousands of households. Existing technologies typically utilize the combination of motors and interferometers to achieve dynamic projection effects. However, the projected image changes periodically, which can cause aesthetic fatigue with prolonged viewing. Therefore, a set of static image projections can be superimposed on a dynamic background of starry sky images to create a more three-dimensional visual effect. However, this type of ambient lighting usually presents images in a slideshow format, often requiring manual image switching, which is cumbersome. Furthermore, the images are usually projector sheets; the more projector sheets available, the more scene options there are, but the higher the cost. Utility Model Content

[0046] The technical solutions in the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0047] The inventors of this application discovered that in existing technical solutions, a motor is used to drive the rotation of the light-transmitting structure, thereby achieving the motion changes of the projected image. However, the projected image changes periodically, which may cause aesthetic fatigue after prolonged viewing, and the switching method of the projected image is abrupt, making it difficult to present a relatively stunning scene.

[0048] In view of this, this application provides an ambient image projection device that can present more realistic and diverse dynamic scenes in order to improve the user experience.

[0049] Implementation Method 1

[0050] The first embodiment of this application proposes an ambient image projection device, see [link to previous document]. Figure 1 and Figure 3 As shown, it includes:

[0051] Display projection module 1 and laser projection module 2 disposed next to display projection module 1;

[0052] The laser projection module 2 includes a laser component 21 and a first optical path module 22. A single laser beam emitted by the laser component 21 passes through the first optical path module 22 to form multiple laser beams and is projected into space.

[0053] The display projection module 1 includes a light source assembly 11, a display screen 12, and a second optical path module 13. The content played on the display screen 12 forms a dynamic image under the guidance of the second optical path module 13 and is projected between the multiple laser beams.

[0054] The content displayed on the screen 12 can form dynamic images and be projected into space. A single laser beam emitted by the laser component 21 passes through the first optical path module 22 to form multiple laser beams, which are also projected into space. These multiple laser beams illuminate the space to form a starry sky image. The starry sky image and the dynamic image at least partially overlap in space, and the starry sky image has a large coverage area, thus providing a more expansive dynamic visual experience. Projecting images through the screen 12 eliminates the need for film, reducing costs. Furthermore, the screen 12 offers a wider and more diverse selection of images, with natural image switching and convenient operation. Compared to existing technologies, this embodiment, by combining starry sky images and dynamic images, not only compensates for the limited viewing range of dynamic images but also avoids the monotony of starry sky images due to insufficient variation. The complementary combination of the two significantly improves the user experience.

[0055] In some preferred embodiments, the first optical path module 22 includes:

[0056] A first grating 223 and a second grating 222 are arranged along the optical path of the laser;

[0057] The single laser beam emitted by the laser component 21 is diffracted into multiple laser beams by the first grating 223, and then diffracted a second time by the second grating 222 to form an irregular optical path.

[0058] By setting the first grating 223 and the second grating 222, on the one hand, the single laser beam emitted by the laser component 21 can be diffracted into multiple laser beams by the first grating 223, and then further diffracted into more laser beams by the second grating 222, thereby increasing the number of laser beams and making the starry sky image formed by the laser beam projection richer; on the other hand, the single laser beam emitted by the laser component 21 passes through the first grating 223 and the second grating 222 in sequence, and under the diffraction effect of the first grating 223 and the second grating 222, the optical path of the laser beam projected by the laser projection module 2 becomes more complex and the projection range is larger, making the starry sky image formed by the laser beam projection closer to the real starry sky effect.

[0059] Furthermore, in order to further improve the diffraction effect of the grating, the density of the diffraction pattern of the first grating 223 is greater than the density of the diffraction pattern of the second grating 222.

[0060] In this embodiment, the display screen 12 can be a liquid crystal display screen 12 with advantages such as low power consumption, small size, and zero radiation; the light emitted by the light source component 11 can illuminate the display screen 12 as a backlight. In another embodiment, the display screen 12 can also be a self-emissive display screen, such as an LED display screen or an OLED display screen, as long as the display screen 12 can form dynamically displayed content.

[0061] The second optical path module 13 may include an optical lens 131 and several lenses; the light source assembly 11 includes a first light source 111 and a focusing element 112; the first light source 111, the focusing element 112, the display screen 12, and the optical lens 131 are arranged sequentially along the optical path followed by the second optical path module 13, with each lens interspersed among the various components of the second optical path module 13. The optical lens 131, several lenses, and the focusing element 112 used in conjunction can make the projected dynamic image clearer and the light output efficiency better.

[0062] To improve image sharpness, a convex lens that converges light can be used. However, if a regular convex lens is used, light refraction only occurs at the interface of the medium, and the lens is relatively thick, causing light to attenuate during propagation, which may result in darkening and blurring at the edges. Therefore, in this embodiment, the lens can be a Fresnel lens. One surface of a Fresnel lens is smooth, while the other surface is engraved with concentric circles of increasing size. Its texture is designed based on light interference, diffraction, relative sensitivity, and receiving angle requirements. Therefore, a Fresnel lens can eliminate the straight-line propagation portion, retaining only the refracting curved surface, saving a significant amount of material while achieving the same light-concentrating effect as a convex lens. In other words, the cost of a Fresnel lens is much lower than that of a regular convex lens.

[0063] The lens may include: a first lens 132 disposed between the light-collecting element 112 and the display screen 12; and a second lens 133 disposed between the display screen 12 and the optical lens 131. The optical lens 131 may include a convex lens 131a, a concave lens 131b, and a fisheye lens 131c disposed sequentially, with the convex lens 131a disposed on the side closer to the display screen 12.

[0064] The first lens 132 and the second lens 133 are designed to better converge light and prevent light energy waste. The convex lens 131a converges light, while the concave lens 131b diverges it. Therefore, by designing the parameters of the convex lens 131a and the concave lens 131b, the projection effect of the image can be well guaranteed, such as the size of the image and image distance, the focusing range, and the image quality. The fisheye lens 131c, as a wide-angle lens, allows the lens to achieve the maximum photographic angle, thus enabling the projection of a larger space in a confined space like an ambient image projection device, improving the space utilization of the device.

[0065] In another implementation, see Figure 2 and Figure 4As shown, the second optical path module 13 may further include a reflector 134, disposed between the second lens 133 and the optical lens 131, with the reflector 134 forming an angle with the display screen 12. When the reflector 134 is disposed at an angle with the display screen 12, it can change the direction of light propagation, so that the light emitted from the second lens 133 is reflected by the reflector 134 and then enters the optical lens 131. Optionally, the reflector 134 forms a 45° angle with the display screen 12, so that the light emitted from the second lens 133 is perpendicular to the light incident on the optical lens 131.

[0066] contrast Figure 1 , Figure 2 It can be seen that, when the lens and the mirror 134 are the same size, Figure 2 The size of components such as the optical lens 131 in the illustrated embodiment can be relatively small; similarly, when the size of components such as the optical lens 131 is the same, the size of the lens and the reflector 134 can be small. In other words, by employing the reflector 134, this embodiment can further improve the space utilization of the ambient image projection device.

[0067] In this embodiment, the light emitted by the first light source 111 is collected by the light-concentrating element 112, projected onto the first lens 132, and converted onto the liquid crystal display screen 12 as backlight. The content on the display screen 12 can be converted into 3D for the first time by the second lens 133, and then projected onto the convex lens 131a and the concave lens 131b for a second conversion, and finally imaged through the fisheye lens 131c.

[0068] The images projected by laser projection module 2 and display projection module 1 are refracted by an irregular dustproof and light-transmitting cover, ultimately forming a dynamic image and a starry sky image, which are then projected into space. For example, the starry sky image may depict a rotating night sky, while the dynamic image could be a rotating Saturn. The starry sky image and the dynamic image at least partially overlap in space, resulting in a dynamic image projected into space with Saturn as the foreground and the night sky as the background. Therefore, this embodiment provides a wide-angle, stereoscopic ambient image projection device with smooth image playback, diverse image selection, compact structure, and low cost, significantly improving the user experience.

[0069] It is worth mentioning that, in this embodiment, the ambient image projection device display projection module 1 and laser projection module 2 can be used independently or in combination according to user needs.

[0070] Implementation Method 2

[0071] The second embodiment of this application proposes an ambient image projection device. This second embodiment is a further improvement upon the first embodiment, the improvement being that, as... Figures 1-4As shown, the first optical path module 22 further includes:

[0072] A rotating shaft and a turntable 221 sleeved on the rotating shaft, the turntable 221 being driven to rotate on the rotating shaft, the turntable 221 being located between the first grating 223 and the second grating 222, and the turntable 221 having a plurality of light-transmitting holes 221a for the laser to pass through.

[0073] When multiple laser beams diffracted by the first grating 223 pass through the turntable 221, some of the laser beams are blocked by the turntable 221, while the other part of the laser beams are directed towards the second grating 222 through the light-transmitting hole 221a. As the turntable 221 rotates, the light-transmitting hole 221a on the turntable 221 rotates with the turntable 221, causing the multiple laser beams diffracted by the first grating 223 to alternately pass through the light-transmitting hole 221a and be directed towards the second grating 222. This results in the light spots formed by the laser beams illuminating space having a flickering appearance, achieving the effect of the starry sky appearing and disappearing in the starry sky image.

[0074] It is worth mentioning that the single laser beam emitted by the laser component 21 can be diffracted into multiple laser beams after passing through the first grating 223; and any one of the multiple laser beams diffracted by the first grating 223 can also be diffracted into multiple laser beams with irregular optical paths after passing through the second grating 222. The light spots formed by these laser beams when projected into space have the characteristics of wide and irregular distribution. In this embodiment, the turntable 221 is set between the first grating 223 and the second grating 222 to block part of the laser beam diffracted by the first grating 223, thereby making the light spots formed by the laser beams in space have a flickering appearance; and the light spots formed by the laser beams in space have the characteristics of wide and irregular distribution, which makes the flickering effect of stars in the projected starry sky image closer to the real starry sky.

[0075] In some other preferred embodiments, the diameters of the plurality of light-transmitting holes 221a are of different sizes. In this embodiment, by setting the diameters of the light-transmitting holes 221a to be of different sizes, the rotation of the turntable 221 results in more variations in the amount of laser beam blocked by the turntable 221, thus improving the irregular flickering appearance of the light spots formed by the laser beam illuminating the space. Similarly, in some other preferred embodiments, the plurality of light-transmitting holes 221a are irregularly distributed on the turntable 221.

[0076] In some embodiments, the laser projection module 2 further includes a drive component 224 connected to the turntable 221 for driving the turntable 221 to rotate. For example, the drive component 224 can be a motor and is connected to the turntable 221 via gears.

[0077] Implementation Method 3

[0078] This embodiment is a further improvement based on the second embodiment, such as... Figures 1-4 As shown, the improvement is that the second grating 222 is connected to the turntable 221 to rotate with the turntable 221.

[0079] As can be seen from the above, a single laser beam emitted by laser component 21 can be diffracted into multiple laser beams after passing through the first grating 223; and any one of the multiple laser beams diffracted by the first grating 223 can also be diffracted into multiple laser beams with irregular optical paths after passing through the second grating 222. The light spots formed by these laser beams projected into space constitute the starry sky image, and each light spot represents a star. By setting the second grating 222 to rotate with the turntable 221, the multiple laser beams diffracted by the second grating 222 exhibit irregular movement, thereby causing the light spots formed after being projected into space to move, achieving the effect of irregular movement of stars.

[0080] In some embodiments, the driving component 224 includes:

[0081] Drive motor;

[0082] A reduction gear set is connected to the drive motor.

[0083] The drive motor provides the driving force for rotation, while the reduction gear set reduces the speed of the drive motor and increases the torque, making the rotation of the turntable 221 more stable and controllable. It is worth mentioning that in this embodiment, the reduction gear set is connected to both the turntable 221 and the second grating 222 to drive them to rotate at different speeds. In this way, by designing the reduction gear set, different speeds can be assigned to the turntable 221 and the second grating 222 to meet practical needs.

[0084] For example, in some embodiments, the reduction gear set includes a first gear and a second gear coaxially arranged. The outer circumferences of the turntable 221 and the second grating are both provided with teeth for connection to the reduction gear set. The first gear meshes with the turntable 221, and the second gear meshes with the second grating. The output shaft of the drive motor can be directly connected to the rotation shafts of the first and second gears, allowing the drive motor to directly drive the first and second gears to rotate. In this embodiment, by setting different tooth ratios between the first gear and the turntable 221 and between the second gear and the second grating, different rotational speeds of the turntable 221 and the second grating 222 can be achieved.

[0085] Implementation Method 4

[0086] To provide users with an immersive experience, the inventors of this application have optimized the design based on the above embodiments to further enhance the projection effect of the ambient image projection device. The ambient image projection device may include a speaker and a controller. The controller is communicatively connected to the display screen 12, the speaker, and the light source assembly 11. The controller provides video signals to the display screen 12 and audio signals to the speaker. The controller also adjusts the intensity or frequency of the light emitted by the light source assembly 11 according to the waveform of the audio signal. This embodiment enables the light intensity of the dynamic image projected by the display projection module 1 to change with the music, providing users with a dual visual and auditory experience and enhancing the enjoyment. For example, when the music is softer, the light source assembly 11 can be dimmed; when the music is louder, the light source assembly 11 can be brightened. When the music rhythm is slower, the light source assembly 11 can flash at a lower frequency; when the music rhythm is faster, the light source assembly 11 can flash at a higher frequency.

[0087] In one embodiment, the controller can also be used to adjust the color of the light emitted by the light source component 11 according to the RGB colors of the video signal. The display screen 12 displays a variety of colors; by analyzing its primary color, the color of the light emitted by the light source component 11 can be adjusted. For example, if the primary color displayed by the display screen 12 is blue, then the light source component 11 can be white, yellow, etc., to improve the overall contrast of the projection effect. Understandably, the higher the contrast, the clearer and more striking the image, and the more vivid and vibrant the colors, which is beneficial for improving the user experience.

[0088] In this embodiment, the controller can be a microcontroller chip integrated on the control circuit board of the light source assembly 11, or it can be set separately. The controller can obtain control signals through a push-button switch or a wireless transceiver, thereby controlling the light intensity of the light source assembly 11. In addition, the control circuit board can rely on DC drive to power the light source assembly 11.

[0089] Implementation Method 5

[0090] This application also provides an atmospheric image projection method, including:

[0091] The single laser beam emitted by the laser component 21 passes through the first optical path module 22 to form multiple laser beams and project them into space;

[0092] The content displayed on the screen 12 is guided by the second optical path module 13 to form a dynamic image, which is then projected between the multiple laser beams.

[0093] The content displayed on the screen 12 can form dynamic images and be projected into space. A single laser beam emitted by the laser component 21 passes through the first optical path module 22 to form multiple laser beams, which are also projected into space. These multiple laser beams illuminate the space to form a starry sky image. The starry sky image and the dynamic image at least partially overlap in space, and the starry sky image has a large coverage area, thus providing a more expansive dynamic visual experience. Projecting images through the screen 12 eliminates the need for film, reducing costs. Furthermore, the screen 12 offers a wider and more diverse selection of images, with natural image switching and convenient operation. Compared to existing technologies, this embodiment, by combining starry sky images and dynamic images, not only compensates for the limited viewing range of dynamic images but also avoids the monotony of starry sky images due to insufficient variation. The complementary combination of the two significantly improves the user experience.

[0094] Compared with the prior art, this embodiment projects images through the display screen 12, eliminating the need for film, thus reducing costs. Furthermore, the display screen 12 provides a wider and more diverse selection of images, with natural image switching and convenient operation, which can greatly improve the user experience.

[0095] In this embodiment, the ambient image projection method may further include:

[0096] Provide video signals to display screen 12 and audio signals to speakers;

[0097] Adjust the intensity or frequency of the light emitted by the light source component 11 into the second optical path module 13 according to the waveform of the audio signal;

[0098] The color of the light emitted by the light source component 11 into the second optical path module 13 is adjusted according to the RGB color of the video signal.

[0099] The light intensity of the dynamic image projected by the display projection module 1 changes with the music, providing users with a dual visual and auditory experience and enhancing the enjoyment. This embodiment adjusts the color of the light emitted by the light source assembly 11 into the second projection mechanism by analyzing the main colors of the display screen 12, thereby improving the contrast between the foreground and background of the overall projection effect. Understandably, the greater the contrast, the clearer and more striking the dynamic image in the foreground, and the more vivid and vibrant the colors, thus providing a more impactful visual effect.

[0100] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
