[0038] Referring to Figures 1 to 5 , an embodiment of the present application provides a photographic and video light 100, which includes a lamp body 10, a light source 20, an electro - control dimming film 30, and a power supply module.

The power supply module is arranged in the lamp body 10 and is electrically connected to the light source 20 and the electro - control dimming film 30 respectively. The power supply module is used to output voltages to the light source 20 and the electro - control dimming film 30 respectively. The light transmittance of the electro - control dimming film 30 can change according to the voltage value it receives, so as to realize the adjustment of the color depth displayed by the electro - control dimming film 30, and further change the brightness of the light color emitted after passing through the electro - control dimming film 30.

[0040] As Figure 1 shown, the photographic and video light 100 can be a bar light, which is a portable photographic device often used in outdoor photographic occasions.

[0041] The photographic and video light 100 may further include a handle 40. The handle 40 can be held by the user during use, facilitating the use of the photographic and video light 100. The handle 40 includes a handle housing, and the power supply module is arranged inside the handle housing. The handle 40 is connected to the lamp body 10, and the power supply module can be electrically connected to the light source 20 on the lamp body 10 to supply power to the light source 20.

[0044] The handle 40 and the lamp body 10 can be set in a detachable form of snap connection. The lamp body 10 is snap-connected to the handle 40, and the first electrical connection terminal abuts against the second electrical connection terminal. The power module of the handle 40 can supply power to the light source 20 through the first electrical connection terminal and the second electrical connection terminal, causing the light source 20 to emit light.

[0045] In an embodiment of the present application, the lamp body 10 may include a housing main body 11 and a lamp cover 12 provided on the housing main body 11. An assembly space 101 is formed by enclosing between the lamp cover 12 and the housing main body 11.

[0046] The photographic and video lamp 100 can be a bar lamp, and the lamp body of the bar lamp can be set in a cylindrical shape to facilitate the user's grip. The lamp body 10 can be correspondingly set in a cylindrical shape. The outer contour of the cross-section of the housing main body 11 is semicircular, and the lamp cover 12 is arc-shaped. The lamp cover 12 and the housing main body 11 jointly enclose a circular outer contour.

[0047] In other embodiments, in addition to being set with a circular outer contour, the bar lamp can also be set in a square, triangular, other regular or irregular shape. The lamp cover 12 and the housing main body 11 are also correspondingly set in the corresponding shape.

[0048] The light source 20 can be a plurality of LED lamp beads, and the plurality of LED lamp beads can be arranged in an array on the surface of the housing main body 11 facing the lamp cover 12. The light emitted by the LED lamp beads can be emitted from the transparently arranged lamp cover 12. In other embodiments, the light source 20 can also be set as other light-emitting elements according to the use requirements.

[0049] In an embodiment of the present application, the lamp cover 12 is detachably provided on the housing main body 11. Through the detachable connection between the lamp cover 12 and the housing main body 11, it is convenient for the user to replace and repair the light source 20, ensuring the service life of the photographic and video lamp 100.

[0050] Wherein, connection grooves 13 are provided on both sides in the width direction of the housing main body 11, and the extending direction of the connection grooves 13 is the same as the length direction of the housing main body 11. In the thickness direction of the housing main body 11, the position of the connection grooves 13 on the housing main body 11 is lower than the surface of the housing main body 11 where the light source 20 is provided.

[0051] Both sides of the lamp cover 12 are provided with connection blocks 14, and the connection blocks 14 are arranged on the inner side wall of the lamp cover 12. In the thickness direction of the housing main body 11, the connection grooves 13 are recessed away from the light source 20, and the edge of the connection grooves 13 and the side of the housing main body 11 form a stepped structure.

[0052] The connecting block 14 includes a main body portion 141 and a clamping portion 142. Among them, the main body portion 141 is connected to the inner side surface of the lamp cover 12 and is arranged close to the edge of the lamp cover 12. The clamping portion 142 is bent and connected to one end of the main body portion 141 facing away from the lamp cover 12, and the clamping portion 142 extends in a direction away from the lamp cover 12.

[0053] When the lamp cover 12 is connected to the housing main body 11, the clamping portion 142 of the connecting block 14 is clamped in the connecting groove 13, and the end surface at the connection portion of the main body portion 141 and the lamp cover 12 abuts against the surface of the housing main body 11 near the connecting groove 13, so that the lamp cover 12 is stably clamped on the housing main body 11.

[0054] In other examples of the present application, the connecting block 14 can also be arranged on the housing main body 11, and the connecting groove 13 can be opened on the lamp cover 12. The detachable connection of the lamp cover 12 on the housing main body 11 is realized through the clamping of the connecting block 14 and the connecting groove 13.

[0055] In some other examples, the lamp cover 12 and the housing main body 11 can also be detachably connected in other ways, such as through a matching structure of a buckle and a hook, through a magnetic adsorption method, etc.

[0056] In addition, in some embodiments of the present application, the lamp cover 12 and the housing main body 11 can also be set as an integral structure, that is, the lamp cover 12 and the housing main body 11 can be integrally formed to ensure the stability of the overall structure of the photographic and video camera lamp 100.

[0057] The electro - controlled dimming film 30 is arranged in the assembly space 101 and is arranged on the light emitting path of the light source 20. The light transmittance of the electro - controlled dimming film 30 can change according to the voltage value it receives, so as to adjust the brightness of the light emitted by the light source 20.

[0058] The electro - controlled dimming film 30 can be a film made of special materials. It usually includes two outer protective films and one or more layers of film materials arranged between the two outer protective films. In this embodiment, the electro - controlled dimming film 30 includes a dimming layer containing liquid crystal molecules. The principle that the electro - controlled dimming film 30 changes the light transmittance of the dimming layer through an alternating voltage is mainly based on the electro - chromic effect and the arrangement change of liquid crystal molecules under the action of an electric field to change its light transmittance. When the electro - controlled dimming film 30 is powered off, the liquid crystal molecules therein will be randomly arranged, causing the light to scatter in all directions, making the dimming layer present a frosted opaque state. When powered on, the liquid crystal molecules will be arranged in a direction perpendicular to the dimming layer, enabling the light to pass through smoothly, so that the dimming layer presents a transparent state. This conversion between the transparent and opaque states can be completed instantly, realizing the atomization and clarity effects of the electro - controlled dimming film 30. And by changing the voltage input to the electro - controlled dimming film 30, the light transmittance of the electro - controlled dimming film 30 can be gradually changed.

[0059] Moreover, the liquid crystal molecules in the dimming layer can be in colors such as white, black, red, green, and blue. Taking the liquid crystal molecules being blue as an example, when powered on, the dimming layer presents a transparent state. As the voltage decreases, the corresponding color of the liquid crystal molecules gradually appears in the dimming layer, that is, changing from light blue to dark blue. Therefore, the light emitted by the light source 20 will have its brightness changed after passing through the electro-control dimming film 30. And because the liquid crystal molecules are arranged at a certain angle, it can also adjust the beam angle of the light passing through the electro-control dimming film 30, thereby adjusting the softness of the light.

[0060] Furthermore, the photographic and video camera light further includes a control circuit board installed in the lamp body, and the control circuit board is electrically connected to the electro-control dimming film 30. In the electro-control dimming film 30, multiple dimming layers containing liquid crystal molecules can be stacked. In each dimming layer, the colors of the liquid crystal molecules are different. For example, the first layer is red, the second layer is blue, and the third layer is green. The control circuit board outputs voltages to each of the dimming layers respectively, so that the color depths presented by each of the dimming layers also change accordingly. If red needs to be displayed, the first layer is powered off and the other two layers are powered on, then the electro-control dimming film 30 will display red. If purple needs to be displayed, the first and second layers are powered off and the third layer is powered on, then the electro-control dimming film 30 will display purple, which is the superposition of red and blue. Therefore, through the superposition and combination of three colors, the electro-control dimming film 30 can present a variety of different colors.

[0061] In some embodiments of the present application, the electro-control dimming film 30 can be disposed on the housing body 11 or directly cover and fix on the light source 20, and the light emitted by the light source 20 can directly pass through the electro-control dimming film 30.

[0062] As Figures 3 to 5 shown, in some other examples of the present application, the electro-control dimming film 30 can be disposed on the inner wall of the lamp cover 12. When the photographic and video camera light 100 is a bar light, the electro-control dimming film 30 can be similarly set in an arc shape corresponding to the shape of the lamp cover 12. The electro-control dimming film 30 can completely cover the inner surface of the lamp cover 12.

[0063] Both side edges of the electro-control dimming film 30 abut against the connection part of the connection block 14 and the lamp cover 12, and the electro-control dimming film 30 can be fixed on the inner wall of the lamp cover 12 by adhesion.

[0064] In some examples, the lamp cover 12 and the housing body 11 are detachably connected. When the lamp cover 12 is in a disassembled state, the lamp cover 12 and the housing body 11 are separated from each other.

[0065] In this example, the photographic and video camera light 100 may further include conductive terminals 51 and a conductive seat 52 that can be conductively docked.

[0066] Among them, the control circuit board is arranged inside the shell body 11. The control circuit board is electrically connected to the power module. The conductive base 52 is arranged on the surface of the shell body 11, and the conductive base 52 is electrically connected to the control circuit board. The conductive terminal 51 is arranged on the electro-control dimming film 30. When the lamp cover 12 is connected to the shell body 11, the conductive terminal 51 is docked with the conductive base 52.

[0067] Through the docking of the conductive terminal 51 and the conductive base 52, an electrical connection can be formed between the power module and the electro-control dimming film 30, so that the control circuit board controls the power module to output different magnitudes of voltage to the electro-control dimming film 30, enabling the electro-control dimming film 30 to change according to the voltage value it receives.

[0068] In some other embodiments of the present application, the lamp cover 12 and the shell body 11 are of an integral structure, that is, the lamp cover 12 and the electro-control dimming film 30 will not be separated from the shell body 11. In this embodiment, the electro-control dimming film 30 can be electrically connected to the power module through a wire.

[0069] In addition, the photographic and video camera lamp 100 may further include a control button 60, and the control button 60 is arranged on the handle shell. The control button 60 is electrically connected to the control circuit board and is used to control the voltage value output by the control circuit board to the electro-control dimming film 30 to adjust the light transmittance of the electro-control dimming film 30.

[0070] When a user uses the photographic and video camera lamp 100, holding the handle 40, the user can press the control button 60 with the thumb to adjust the light transmittance of the electro-control dimming film 30, thereby realizing the adjustment of the brightness of the light of the photographic and video camera lamp 100 to select a suitable light in real time.

[0071] Refer to Figure 6 and Figure 7 In some other examples of the present application, the photographic and video camera lamp 100 may also be a panel lamp. The lamp body 10 of the photographic and video camera lamp 100 includes a shell body 11 and a lamp cover 12 arranged on the shell body 11. Among them, the shell body 11 is the main body structure of the panel lamp, and its structure is substantially the same as that of the existing panel lamp.

[0072] The main difference from the above embodiment is that an installation groove 102 is recessed on the surface of the shell body 11. The lamp cover 12 is arranged at the notch of the installation groove 102, and the electro-control dimming film 30 is arranged on the inner wall of the lamp cover 12; and both the lamp cover 12 and the electro-control dimming film 30 are of a flat plate structure.

[0073] The lamp cover 12 and the shell body 11 can be arranged to be detachably connected. In this example, the photographic and video camera lamp 100 may further include a control circuit board, and a first contact 71 and a second contact 72 that can be conductively docked.

[0074] Among them, the control circuit board is arranged inside the housing main body 11 and is electrically connected to the power module. The second contact 72 is arranged on the surface of the housing main body 11, and the second contact 72 is electrically connected to the control circuit board. The first contact 71 is arranged on the electro-control dimming film 30. When the lamp shade 12 is connected to the housing main body 11, the first contact 71 abuts against the second contact 72.

[0075] Through the contact and cooperation between the first contact 71 and the second contact 72, an electrical connection can be formed between the control circuit board and the electro-control dimming film 30, so that the control circuit board controls the power module to output different magnitudes of voltage to the electro-control dimming film 30, enabling the electro-control dimming film 30 to change according to the voltage value it receives.

[0076] Refer to Figure 8 , in some other examples of the present application, the photographic and video lamp 100 can also be a distributed lamp. The lamp main body 10 and the electro-control dimming film 30 of the distributed lamp are both flexible components, and the electro-control dimming film 30 covers the surface of the lamp main body 10. Therefore, the lamp main body 10 and the electro-control dimming film 30 can be rolled up and stored together.

[0077] The lamp main body 10 and the electro-control dimming film 30 of the distributed lamp can be set to be detachably connected. In this example, the lamp main body 10 and the electro-control dimming film 30 can be connected through a detachable and connectable component 81, and the detachable and connectable component 81 can be a magic tape, snap button, magnetic attraction component, etc.; in this example, the photographic and video lamp 100 can also include a control circuit board and conductive contacts 82 capable of docking and conducting electricity. Through the conductive contacts 82, an electrical connection can be formed between the control circuit board and the electro-control dimming film 30, so that the control circuit board controls the power module to output different magnitudes of voltage to the electro-control dimming film 30, enabling the electro-control dimming film 30 to change according to the voltage value it receives.

[0078] Refer to Figure 9 , and in some other embodiments, the lamp main body 10 and the electro-control dimming film 30 of the distributed lamp can be set to be a fixed structure, and the electro-control dimming film 30 can be attached to the light-emitting surface on the surface of the lamp main body 10.

[0079] Refer to Figure 10 and Figure 11 , in some other examples of the present application, the photographic and video lamp 100 can also be an LED film and television lamp for photographic and video. The light source 20 is a COB (Chip On Board) light source, and the electro-control dimming film 30 covers the light-emitting surface of the COB light source through a light-transmitting plate. Among them, the COB light source is a high-power integrated surface light source, a high-light-efficiency integrated surface light source technology in which LED chips are directly attached to a highly reflective mirror metal substrate, and the light-transmitting plate can be a heat-insulating glass plate; among them, the lamp main body 10 of the LED film and television lamp is substantially the same as the structure of the existing LED film and television lamp.

[0080] In addition, besides the bar lights, panel lights, cloth lights, and LED film and television lights shown in this application, the structural form of the photographic and video light 100 can also be other lighting devices, such as flashlights, spotlights, ambient lights, and so on.

[0081] For the photographic and video light of this application, it includes a lamp body, a light source, an electro-controlled dimming film, and a power supply module. The electro-controlled dimming film is arranged on the light-emitting path of the light source, and the light emitted by the light source can be emitted from the surface of the lamp body through the electro-controlled dimming film. The light transmittance of the electro-controlled dimming film can change according to the voltage value it receives, thereby realizing the adjustment of the depth of the color it displays, so as to adjust the brightness of the light emitted by the light source. This enables users to adjust the light brightness without replacing color filters with different light transmittances. The overall structure of the photographic and video light is simple and easy to operate, which can well meet different shooting requirements and the fast pace of the shooting scene, ensuring a high-quality user experience.
