[0029] Traditional soft light screens are usually composed of one or more liquid crystal molecular layers sandwiched between two pieces of glass. They are made of hard materials as a whole. Moreover, in order to obtain a larger soft light illumination range, the volume of traditional soft light screens is generally designed to be relatively large, making it extremely inconvenient to carry and store them during outdoor shooting. Therefore, this embodiment provides a soft light device and a soft light system that are convenient to carry and store.

[0030] Please refer to Figures 1 to 6 , the soft light device 100 of this embodiment includes an electrically controlled atomizing screen 120 and a rotating shaft 110.

[0031] The electrically controlled atomizing screen 120 is a flexible screen. The rotating shaft 110 is fixed to the side of the flexible electrically controlled atomizing screen 120 and can rotate around its own axis. The rotating shaft 110 can roll up or unfold the electrically controlled atomizing screen 120, so that the storage space of the entire soft light device 100 is small, which is convenient for users to carry and store.

[0032] Please refer to Figure 3 , in some embodiments, the electrically controlled atomizing screen 120 includes an electrically controlled dimming layer 122 and transparent substrate layers 123 disposed on both sides of the electrically controlled dimming layer 122. The electrically controlled dimming layer 122 can change its atomization degree according to an external electrical signal to scatter the light passing through the electrically controlled atomizing screen 120. Moreover, both the electrically controlled dimming layer 122 and the transparent substrate layers 123 are flexible members, so that they can be folded and rolled up.

[0033] Specifically, the electrically controlled dimming layer 122 can be a flexible thin film having liquid crystal molecules. Its principle is mainly based on the electrochromic effect and the arrangement change of liquid crystal molecules under the action of an electric field to change its atomization degree, that is, by changing the alternating voltage at both ends to change its atomization degree, and then scattering and softening the passing light.

[0034] Exemplarily, when the electro - controlled dimming layer 122 is powered off, the liquid crystal molecules in it will be randomly arranged, causing light to scatter in all directions, making it present a frosted or milky white opaque state. When powered on, the liquid crystal molecules will be arranged in a direction perpendicular to the dimming film, enabling light to pass through smoothly, thus making it present a transparent state. The conversion between this transparent and opaque state can be completed instantaneously, achieving the atomization and clear effects. By changing the voltage input to the electro - controlled dimming layer 122, the degree of opacity of the electro - controlled dimming layer 122, that is, the atomization degree, can be changed, thereby changing the soft - light effect of the electro - controlled atomization screen 120.

[0035] Please refer to Figure 3 , in some embodiments, the transparent substrate layer 123 can be located on both sides of the electro - controlled dimming layer 122 to sandwich the electro - controlled dimming layer 122 between two transparent substrate layers 123, so as to play a role in supporting and protecting the electro - controlled dimming layer 122.

[0036] Among them, the transparent substrate layer 123 is made of a flexible material and can be tightly combined with the flexible electro - controlled dimming layer 122 to ensure the strength and durability of the overall flexible screen. The transparent substrate layer 123 can be a flexible material such as polyester plastic, which can not only provide high transparency but also has good flexibility and durability, so that the electro - controlled atomization screen 120 will not be damaged during multiple winding and unfolding processes.

[0037] Please refer to Figure 1 , in some embodiments, the soft - light device 100 further includes an electro - controlled connector 130. One end of the electro - controlled connector 130 is electrically connected to the electro - controlled atomization screen 120, and the other end of the electro - controlled connector 130 is used to conduct with an external device, so that the external device can control the atomization degree of the electro - controlled atomization screen 120.

[0038] Specifically, one end of the electro - controlled connector 130 is electrically connected to the electro - controlled atomization screen 120, responsible for transmitting signals to the electro - controlled atomization screen 120. The other end of the electro - controlled connector 130 is used to communicate with an external device, and the external device can be a control device such as a smart phone, a remote control or a photography console. At this time, the external device can send different electrical signals to the atomization screen through the electro - controlled connector 130 to adjust the atomization degree of the electro - controlled atomization screen 120 in real time, so as to remotely adjust the softness of the light passing through the electro - controlled atomization screen 120.

[0039] Please refer to Figure 1 and Figure 2 , in some embodiments, there is at least one rotating shaft 110, which is fixed on the side of the electro - controlled atomization screen 120 and can rotate around its own axis to enable the electro - controlled atomization screen 120 to be rolled up for storage or unfolded for use.

[0040] When not in use, the user can quickly roll up the electric-controlled mist screen 120, which greatly improves portability; when in use, the user only needs to unfold the electric-controlled mist screen 120 on the shaft 110 to quickly spread out the screen to soften the light, and the entire operation process is simple and convenient.

[0041] In some embodiments, the shaft 110 may be cylindrical and its length may be slightly greater than the width of the electric-controlled mist screen 120 , so that the two ends of the shaft 110 extending out of the electric-controlled mist screen 120 can be connected to an external bracket to facilitate the installation of the soft light device 100 .

[0042] In some embodiments, the rotating shaft 110 may be made of a light and strong material, such as aluminum alloy or carbon fiber, etc., to ensure that the overall weight of the light softening device 100 is light and provide sufficient mechanical strength.

[0043] See also Figure 4 In some embodiments, the rotating shaft 110 may include an axis core 111 and a sleeve 112. The sleeve 112 may be sleeved on the axis core 111 and may rotate relative to the axis core 111. The length of the sleeve 112 may be the same as the width of the electric-controlled atomization screen 120, and the length of the axis core 111 may be greater than the length of the sleeve 112, so that both ends of the axis core 111 may be connected to an external bracket, and the outer wall of the sleeve 112 is fixedly connected to the side of the electric-controlled atomization screen 120. When the sleeve 112 rotates around the axis core 111, the electric-controlled atomization screen 120 may be rolled up on the outer wall of the sleeve 112.

[0044] In some other embodiments, the rotating shaft 110 may also be composed of three sections of rod bodies. The rod body in the middle section is rotatably connected to the rod bodies at both ends, the rod body in the middle section is fixedly connected to the side of the electric-controlled atomizing screen 120, and the rod bodies at both ends may be connected to external brackets. When the rod body in the middle section rotates relative to the rod bodies at both ends, the electric-controlled atomizing screen 120 can be rolled up.

[0045] In some embodiments, the light softening device 100 may further include a driving member 140. The driving member 140 may be in transmission connection with the rotating shaft 110, and the driving member 140 may drive the rotating shaft 110 to rotate around its own axis, thereby realizing automatic unfolding and retracting of the electrically controlled atomizing screen 120 when in use.

[0046] Specifically, the driving member 140 may be a stepper motor or a servo motor, which may be disposed at the end or inside of the rotating shaft 110. The power output end of the servo motor may be directly connected to the end of the rotating shaft 110 to drive the rotating shaft 110 to rotate as a whole. Alternatively, the power output end of the servo motor may be connected to the sleeve 112 or the middle section of the rotating shaft 110 to drive it to rotate, thereby automatically reeling or unfolding the electric-controlled atomization screen 120 from the rotating shaft 110.

[0047] In some embodiments, the driving member 140 can also be electrically connected to the electric control connector 130, so that the external device can remotely control the driving member 140. When the soft light device 100 is in use, the user can control the electric control atomizing screen 120 to automatically unfold or wind up on the rotating shaft 110 through the external device, so as to improve the use convenience of the soft light device 100.

[0048] Please refer to Figure 5 and Figure 6 , in some embodiments, two rotating shafts 110 can be provided, and the two rotating shafts 110 can be respectively arranged on the opposite sides of the electric control atomizing screen 120. Both of the two rotating shafts 110 can rotate around their own axes to wind up or unfold the electric control atomizing screen 120.

[0049] Specifically, the two rotating shafts 110 are arranged in parallel on the opposite side edges of the electric control atomizing screen 120 and can independently rotate around their respective axes, so as to realize the synchronous winding up or unfolding of the electric control atomizing screen 120. Compared with the single rotating shaft 110 design, the two rotating shafts 110 can more evenly disperse the tension of the electric control atomizing screen 120 and avoid the screen curling or damage caused by one-sided rotation.

[0050] Please refer to Figure 5 , in some embodiments, the electric control atomizing screen 120 further includes a plurality of light-transmitting areas 121. The light-transmitting areas 121 are arranged on the transparent substrate layer 123, and the plurality of light-transmitting areas 121 are arranged at intervals along the winding up or unfolding direction of the electric control atomizing screen 120, and the wavelength range of the light that each light-transmitting area 121 can pass through is different.

[0051] Some special shooting scenes require light of different wavelengths to create a unique visual effect. For example, in stage photography or drama performances, light of a specific wavelength can create different atmospheres after passing through the electric control atomizing screen 120. Therefore, in this embodiment, a plurality of light-transmitting areas 121 are provided on the electric control atomizing screen 120, and each light-transmitting area 121 can transmit light of different colors. By controlling the different light-transmitting areas 121 on the electric control atomizing screen 120 to correspond to the light emitted by the flash, the color of the light at the shooting scene can be changed. At this time, the electric control atomizing screen 120 not only has the effect of soft light, but also can control the color of the light passing through it, thereby changing the light color at the shooting scene to create different atmospheres.

[0052] For example, when a romantic scene needs to be created on site, the rotating shaft 110 can be rotated to make the red light-transmitting area 121 on the electric control atomizing screen 120 face the flash or other light sources. At this time, after the light passes through the red light-transmitting area 121 on the electric control atomizing screen 120, not only will the light become softer, but also the light passing through will all become red light. It can effectively meet the requirements of different shooting scene needs and improve the practical performance of the soft light device 100.

[0053] Furthermore, the light-transmitting area 121 on the electrically-controlled atomizing screen 120 can be formed in a variety of structural forms. For example:

[0054] In some embodiments, a plurality of color coatings of different colors are spaced apart on the transparent substrate layer 123, and the color coatings are coated on the side of the transparent substrate layer 123 facing the electrically-controlled dimming layer 122 or on the side away from the electrically-controlled dimming layer 122; so that different color coating structures on the transparent substrate layer 123 form different light-transmitting areas 121.

[0055] Specifically, the coating of the corresponding color can only pass the light of the corresponding color wavelength. The color coating can be coated on the outer side and / or inner side of the transparent substrate layer 123 according to specific needs. The inner side and the outer side are sides perpendicular to the light, so that the light can pass through the color coating to create different shooting atmospheres and environments, thereby enhancing the adaptability and flexibility of the soft light device 100. In addition, by applying the color coating to change the wavelength of light that can pass through the electric-controlled atomizing screen 120, the user can apply the desired color of the light-transmitting area 121 according to his own needs, which is more personalized.

[0056] In some other embodiments, the electrically controlled atomization screen 120 may include a color sheet which is attached or laminated on the side of the transparent substrate layer 123 and has different color regions to form different light-transmitting regions 121 .

[0057] Specifically, the color patch with different color areas is attached to the side of the transparent substrate layer 123, so that the soft light part and the color changing part of the electric-controlled atomizing screen 120 are separated. When the color of the light does not need to be changed, the color patch can be taken off, and when the color of the light needs to be changed, the color patch can be attached to the transparent substrate layer 123; when the color of the light that can be transmitted by a certain light-transmitting area 121 needs to be changed, the color patch of different colors can also be replaced. It is more convenient to change the color of the light that can be transmitted, which can effectively improve the convenience of use of the soft light device 100.

[0058] When it is necessary to change a different light-transmitting area 121, the color sheet attached to the transparent substrate layer 123 can be moved together with the transparent substrate layer 123 and the electrically controlled dimming layer 122. Of course, the color sheet can also be stacked on the transparent substrate layer 123 without being linked with it. In this case, separate drive shafts can be set on both sides of the color sheet, and the drive shafts can be used to drive the color sheet to roll up separately to change the corresponding light-transmitting area 121; and the transparent substrate layer 123 and the electrically controlled dimming layer 122 are in an unfolded and fixed state, and their positions do not change.

[0059] In some other embodiments, the transparent substrate layer 123 may be a polyester plastic with different colors, so that different color regions on the transparent substrate layer 123 are configured to form different light-transmitting regions 121.

[0060] Specifically, the transparent substrate layer 123 is made of polyester plastics of different colors. This plastic has high light transmittance and good flexibility, and can exhibit different color characteristics while maintaining transparency. The color of the polyester plastic is not achieved through a surface coating, but by adding different dyes or pigments to the material, so that internal color regions are formed during manufacturing. The dye molecules in the polyester plastic are firmly bonded to the plastic substrate, have high color stability, and can maintain the color unchanged during long-term use and multiple winding or unwinding processes. The light transmitted through it will be more uniform.

[0061] In some other embodiments, the liquid crystal molecules in the electro-control dimming layer 122 can also be dyed, that is, different dyes or color-developing components are added to the liquid crystal molecules. When light passes through this liquid crystal molecule layer, not only can the light scattering degree be adjusted electronically, but also the color of the light can be further adjusted by the added dyes or color-developing components.

[0062] Please refer to Figure 7 , in some embodiments, the soft light device 100 may further include a transmission belt 150. The transmission belt 150 is respectively connected to the two rotating shafts 110, and can drive the two rotating shafts 110 to rotate synchronously in opposite directions, so that the electro-control atomization screen 120 is transferred from one rotating shaft 110 to the other rotating shaft 110, and then the light-transmitting region 121 on the electro-control atomization screen 120 between the two rotating shafts 110 is switched.

[0063] Among them, the transmission belt 150 is used for transmission between the two rotating shafts 110. When the soft light device 100 is in normal use, the two rotating shafts 110 are far away from each other and relatively fixed on the external bracket. At this time, the driving member 140 can drive one of the rotating shafts 110 to rotate, and the other rotating shaft 110 is driven by the transmission belt 150, so that the rotation directions and speeds of the two rotating shafts 110 are the same. The electro-control atomization screen 120 located between the two rotating shafts 110 will be wound and transferred from one rotating shaft 110 to the other rotating shaft 110, and then the light-transmitting region 121 between the two rotating shafts 110 changes, so that the soft light device 100 can transmit light of different colors.

[0064] Of course, in some other embodiments, the soft light device 100 may not be provided with the transmission belt 150, but driving members 140 are connected to the ends of the two rotating shafts 110. The two driving members 140 can be servo motors, and the two servo motors can drive the two rotating shafts 110 to rotate synchronously under the action of an electrical signal, so that the electro-control atomization screen 120 is smoothly wound and transferred from one rotating shaft 110 to the other rotating shaft 110, and then the light-transmitting region 121 is adjusted and switched.

[0065] Please refer to Figure 7 Figure 7 , the soft light system 200 of this embodiment includes a support frame 210 and a soft light device 100. Among them, a light-transmitting window is formed inside the support frame 210; the rotating shaft 110 of the soft light device 100 is connected to the support frame 210, and the electro-controlled atomization screen 120 covers the inside of the light-transmitting window, and light can pass through the electro-controlled atomization screen 120 inside the light-transmitting window and be emitted after softening.

[0066] Among them, the support frame 210 includes a support rod 211 connected to an external bracket, and a support arm 212 connected to the end of the support rod 211. The support arm 212 is U-shaped. Of course, the entire support frame 210 can also be a rectangular frame, as long as it has a window for accommodating the electro-controlled atomization screen 120, and no specific limitation is made here.

[0067] As Figure 7 shown, when softening light is required, the soft light device 100 can be installed on the support frame 210. The two rotating shafts 110 of the soft light device 100 can be respectively located on the upper and lower sides of the support arm 212 to unfold the electro-controlled atomization screen 120. At this time, the driving member 140 can be arranged at one end of one of the rotating shafts 110, and the two rotating shafts 110 can be driven by a transmission belt 150. When the driving member 140 drives one of the rotating shafts 110 to rotate, the two rotating shafts 110 rotate synchronously, and the electro-controlled atomization screen 120 transfers from one rotating shaft 110 to the other rotating shaft 110, and the light-transmitting area 121 between the two rotating shafts 110 changes.

[0068] Of course, in some other embodiments, the soft light device 100 with only one rotating shaft 110 can also be installed on the support frame 210. At this time, the rotating shaft 110 is installed on the upper side of the support frame 210. When the driving member 140 drives the rotating shaft 110 to rotate, the electro-controlled atomization screen 120 can be automatically wound or unfolded from the rotating shaft 110.

[0069] In summary, the present application provides a soft light device 100 and a soft light system 200; the soft light device 100 includes an electro-controlled atomization screen 120 and a rotating shaft 110. The electro-controlled atomization screen 120 can effectively scatter light, making the light shine on the object to be photographed more evenly and softly. Among them, the electro-controlled dimming layer 122 and the transparent substrate layer 123 of the electro-controlled atomization screen 120 are designed as flexible members, and at least one rotatable rotating shaft 110 is arranged on the side of the electro-controlled atomization screen 120. The rotating shaft 110 can rotate around its own axis to wind or unfold the electro-controlled atomization screen 120. It can effectively solve the problems of large volume, heavy weight and inconvenient carrying of the existing rigid soft light screen; significantly improve the portability and storage convenience of the device, and is particularly suitable for outdoor shooting scenes.
