[0034] See Figures 1 to 3 An embodiment of the present application provides a flash 100 that can be mounted on top of a camera or placed separately to provide fill light for a subject or a shooting environment. The flash 100 includes a housing 10, a light source 20, a diffuser lens 30, and a driver assembly 50.

[0035] Among them, an installation space 102 is formed inside the shell 10, and a light outlet 101 connected to the installation space 102 is provided on the shell 10. The light source 20 is arranged in the installation space 102 and corresponding to the light outlet 101. The flash light emitted by the light source 20 can be emitted from the light outlet 101. The diffusion lens 30 is movably arranged on the shell 10, so as to be relatively close to the light outlet 101 and cover the light outlet 101 or relatively far away from the light outlet 101 and move out from the light outlet 101. The driving component 50 can drive the diffusion lens 30 to move relative to the shell 10. When the diffusion lens 30 covers the light outlet 101, the flash light emitted by the light source 20 passes through the diffusion lens 30 and is emitted from the light outlet 101; when the diffusion lens 30 is moved out from the light outlet 101, the flash light emitted by the light source 20 is directly emitted from the light outlet 101.

[0036] Combine Figure 1 and Figure 4 As shown, in some embodiments of the present application, the housing 10 is a box-shaped structure as a whole, which may include a housing body 11 and a cover body 12 connected to the housing body 11. A mounting opening 111 is formed on one side of the housing body 11, and the cover body 12 is fixedly mounted on the mounting opening 111. The cover body 12 is connected to the housing body 11 to enclose a box-shaped structure.

[0037] In other embodiments, the housing 10 may also be configured into other structures according to usage requirements, such as a ring-shaped structure, a disc-shaped structure, a trumpet-shaped structure, etc.

[0038] The housing body 11 defines an installation space 102. A light outlet 101 is provided on the side of the housing body 11 facing the installation opening 111, communicating with the installation space 102. A light source 20 is located within the installation space 102, corresponding to the light outlet 101. Flashlight emitted by the light source 20 can be emitted through the light outlet 101.

[0039] In the present application, the light source 20 may be a xenon lamp or an LED lamp. A capacitor may be used to store high voltage electricity, and a pulse trigger may be used to discharge the xenon lamp or the LED lamp, thereby achieving an instantaneous flash.

[0040] In some embodiments of the present application, the flash 100 further includes a Fresnel lens 40 , which is disposed on the housing 10 and arranged on the side of the light outlet 101 facing away from the light source 20 . The flash light emitted from the light outlet 101 can be emitted after passing through the Fresnel lens 40 .

[0041] In some embodiments, the cover 12 is provided with an assembly opening 121, which corresponds to the light outlet 101. The Fresnel lens 40 is disposed at the assembly opening 121 of the cover 12. The flash light emitted by the light source 20 is first emitted through the light outlet 101, and then emitted after being processed by the Fresnel lens 40.

[0042] Fresnel lens 40 is a special lens with concentric rings etched on its surface, increasing in size. Flashlight rays are deflected as they pass through Fresnel lens 40, converging them to a common focal point. This maximizes the amount of light hitting the surface of an object, effectively enhancing the lighting effect of flashlight 100.

[0043] In some embodiments of the present application, the cover 12 can be omitted, that is, the light outlet 101 and the assembly opening 121 are the same opening, and the light outlet 101 is directly provided on the housing 10. The Fresnel lens 40 can be directly provided at the light outlet 101, and the light source 20 is provided in the installation space 102 inside the housing 10. The flash light emitted by the light source 20 passes through the Fresnel lens 40 and is emitted to the outside of the housing 10.

[0044] Furthermore, if Figure 2 、 Figure 3 as well as Figure 5 As shown, in some embodiments of the present application, the flash 100 further includes a diffusion lens 30. The diffusion lens 30 is movably disposed on the housing 10 to be relatively close to the light outlet 101 to cover the light outlet 101 or relatively far away from the light outlet 101 to be moved out of the light outlet 101.

[0045] When the diffuser lens 30 covers the light outlet 101, the flash light emitted by the light source 20 first passes through the diffuser lens 30, then passes through the Fresnel lens 40, and is emitted to the outside of the housing 10. When the flash light passes through the diffuser lens 30, the diffuser lens 30 can scatter the flash light, dispersing the flash light so that the flash light is spread over a wider illumination range, thereby expanding the illumination range of the flash lamp 100.

[0046] When the flash lamp 100 of the present application is used, it is combined with Figure 2 and Figure 3 The user can move the diffuser lens 30 according to usage needs, so that the diffuser lens 30 covers the light outlet 101 or moves the diffuser lens 30 out of the light outlet 101. Specifically, when the user is taking long-range or wide-angle shots, the user can move the diffuser lens 30 to the light outlet 101 so that the flash light emitted by the light source 20 first passes through the diffuser lens 30 and then passes through the Fresnel lens 40 before being emitted to the outside of the housing 10; when the user is taking close-up shots, the user can move the diffuser lens 30 out of the light outlet 101 so that the flash light emitted by the light source 20 directly passes through the Fresnel lens 40 before being emitted.

[0047] In the technical solution shown in this application, the movement direction of the diffusion lens 30 relative to the shell 10 is not limited. It can move up and down along the height direction of the shell 10, move left and right along the length direction of the shell 10, and move forward and backward along the width direction of the shell 10.

[0048] That is, the direction of movement of the diffuser lens 30 relative to the housing 10 can be determined based on the specific structure of the flash 100 and the location of the light outlet 101, and is not limited to up and down, left and right, or front and back. The following text and the accompanying drawings illustrate an example in which the diffuser lens 30 moves up and down along the height direction of the housing 10.

[0049] Furthermore, in some embodiments of the present application, the driving assembly 50 includes a linkage 51, which is rotatably disposed on the housing 10, and the diffuser lens 30 is connected to the linkage 51. The linkage 51 rotates relative to the housing 10 to enable the diffuser lens 30 to move relative to the housing 10.

[0050] In some examples, combined Figure 2 、 Figure 3 as well as Figure 6 As shown, the linkage member 51 may be a wheel-shaped structure, and the linkage member 51 is arranged inside the housing 10 .

[0051] The linkage member 51 is provided with a plurality of interlocking teeth 511 at intervals along its outer periphery. The linkage member 51 is a gear structure. The linkage member 51 is rotatable relative to the housing 10 along its own axis, with the axis of rotation aligning with the length of the housing 10. The diffuser lens 30 moves vertically along the height of the housing 10, with the axis of rotation of the linkage member 51 perpendicular to the direction of movement of the diffuser lens 30.

[0052] In this example, the drive assembly 50 further includes a follower 52 having a follower tooth 521 formed on one side thereof for engaging with the linkage tooth 511. The follower 52 is meshedly connected to the linkage 51. The diffuser lens 30 is connected to the follower 52. When the linkage 51 rotates relative to the housing 10, the linkage 51 drives the follower 52 to move linearly and reciprocally along the height direction of the housing 10, thereby causing the diffuser lens 30 to move up and down relative to the housing 10.

[0053] like Figure 3 As shown, when the linkage member 51 rotates forward relative to the housing 10, the follower 52 can move downward along the height direction of the housing 10 as the linkage member 51 rotates, thereby moving the diffusion lens 30 out of the light outlet 101. Figure 2As shown, when the linkage member 51 rotates in the opposite direction relative to the housing 10 , the follower 52 can move upward along the height direction of the housing 10 as the linkage member 51 rotates, thereby moving the diffusion lens 30 to the light outlet 101 and covering the light outlet 101 .

[0054] In this example, the diffuser lens 30 includes a mirror body 31 and a mounting frame 32. The mirror body 31 is used to diffuse light. The mounting frame 32 defines a mounting location within which the mirror body 31 is disposed. The mounting frame 32 has a longitudinal direction aligned with the longitudinal direction of the housing 10, and one end of the mounting frame 32 is fixedly connected to the follower 52.

[0055] The installation frame 32 not only connects the mirror body 31 with the follower 52 , but also protects the mirror body 31 , preventing the mirror body 31 from being damaged during movement, thereby ensuring the overall service life of the flash lamp 100 .

[0056] The inner wall of the housing 10 may be provided with a stopper 103. The stopper 103 may be provided on both inner walls of the housing 10 in the height direction. The stopper 103 may abut against the mounting frame 32 of the diffuser lens 30 to stop the diffuser lens 30 when the diffuser lens 30 moves upward or downward, thereby reminding the user to move the diffuser lens 30 into position and preventing the diffuser lens 30 from excessively moving and causing it to be misaligned relative to the light outlet 101.

[0057] like Figure 5 and Figure 6 As shown, in this example, a protrusion 522 is formed on the surface of the follower 52, and a slide groove 104 is provided on the inner wall of the housing 10. The extension direction of the slide groove 104 is consistent with the height direction of the housing 10, that is, consistent with the movement direction of the diffuser lens 30, and the protrusion 522 is movably disposed in the slide groove 104.

[0058] By moving the protrusion 522 in the slide groove 104, the moving direction of the follower 52 can be effectively limited, avoiding the follower 52 from being offset, and ensuring that the follower 52 moves up and down along the height direction of the shell 10, thereby effectively limiting the moving direction of the diffusion lens 30.

[0059] In addition, in some embodiments of the present application, the driving assembly 50 may further include a toggle button 53 . The toggle button 53 is connected to the linkage member 51 and is rotatably disposed on the outside of the housing 10 .

[0060] The toggle button 53 is used for manual rotation by the user to realize the rotation of the linkage member 51 relative to the housing 10. Specifically, Figure 3As shown, the push button 53 can be pushed upward to make the linkage 51 rotate forward relative to the housing 10, and the follower 52 can move downward along the height direction of the housing 10 as the linkage 51 rotates, thereby moving the diffusion lens 30 out of the light outlet 101. Figure 2 As shown, the toggle button 53 can be pushed downward to make the linkage 51 rotate in the opposite direction relative to the shell 10. The follower 52 can move upward along the height direction of the shell 10 as the linkage 51 rotates, thereby moving the diffusion lens 30 to the light outlet 101 and covering the light outlet 101.

[0061] In addition to the aforementioned manual operation of the toggle button 53 to achieve the up and down movement of the diffusion lens 30 , in some embodiments of the present application, the driving assembly 50 may include a driving motor.

[0062] The power shaft of the driving motor is connected to the linkage member 51. When the driving motor is energized, the linkage member 51 rotates, so that the linkage member 51 drives the diffusion lens 30 to move relative to the housing 10. The driving motor drives the diffusion lens 30 to move, making the flashlight 100 more automated to use.

[0063] Furthermore, in addition to the gear structure of the linkage member 51 shown above, in some embodiments of the present application, the linkage member 51 can also be a rod-shaped structure with an external thread on the outer periphery of the linkage member 51, that is, the linkage member 51 is a screw structure. The linkage member 51 can be rotatably mounted on the housing 10 along its own axis, and the axis direction of the linkage member 51 is consistent with the height direction of the housing 10.

[0064] In this embodiment, the drive assembly 50 further includes a follower 52 that is sleeved onto the exterior of the linkage member 51. The diffuser lens 30 is connected to the follower 52. The inner wall of the follower 52 is provided with internal threads that threadably engage with the external threads. The follower 52 is threadedly engaged with the linkage member 51. When the linkage member 51 rotates relative to the housing 10, the linkage member 51 drives the follower 52 to reciprocate linearly along the height direction of the housing 10, thereby causing the diffuser lens 30 to move up and down relative to the housing 10.

[0065] The linkage member 51 can be set to rotate clockwise or counterclockwise about its own axis. Specifically, when the linkage member 51 rotates clockwise relative to the housing 10, the follower 52 can move downward along the height direction of the housing 10 as the linkage member 51 rotates, thereby moving the diffuser lens 30 out of the light outlet 101. When the linkage member 51 rotates counterclockwise relative to the housing 10, the follower 52 can move upward along the height direction of the housing 10 as the linkage member 51 rotates, thereby moving the diffuser lens 30 to the light outlet 101 and covering the light outlet 101.

[0066] Furthermore, in some embodiments of the present application, a corresponding powered driving assembly 50 may be provided inside the housing 10 , and the driving assembly 50 drives the diffusion lens 30 to perform linear reciprocating motion relative to the housing 10 .

[0067] Specifically, in some examples, the driving assembly 50 can be a rod motor. The output shaft of the rod motor is connected to the diffuser lens 30. The rod motor drives the diffuser lens 30 to move relative to the housing 10, so that the diffuser lens 30 can move to the light outlet 101 to cover the light outlet 101, and can move away from the light outlet 101 to be removed from the light outlet 101.

[0068] In some examples, the drive assembly 50 may also be a hydraulic cylinder. The hydraulic cylinder includes a cylinder body disposed on the housing 10 and a drive rod linearly and telescopically disposed on the cylinder body. The drive rod is connected to the diffuser lens 30 and linearly and telescopically drives the diffuser lens 30 to move relative to the housing 10, thereby enabling the diffuser lens 30 to move to the light outlet 101 to cover the light outlet 101 and to move away from the light outlet 101 to be removed from the light outlet 101.

[0069] In other examples, the drive assembly 50 may also be a cylinder. The cylinder includes a cylinder body mounted on the housing 10 and a drive rod linearly and telescopically mounted on the cylinder body. The drive rod is connected to the diffuser lens 30 and linearly and telescopically drives the diffuser lens 30 to move relative to the housing 10, thereby enabling the diffuser lens 30 to move to the light outlet 101 to cover the light outlet 101 and to move away from the light outlet 101 to be removed from the light outlet 101.

[0070] Taking the structure of the flash 100 shown in the drawings of this application as an example, when in use, the flash 100 can be installed on a camera, or it can be placed outside the camera in an environment where fill light is required. Specifically, when the user is taking a long-range or wide-angle shot, the user can toggle the toggle button 53 downward to cause the linkage 51 to rotate in the opposite direction relative to the housing 10. The follower 52 can move upward along the height direction of the housing 10 as the linkage 51 rotates, thereby moving the diffuser lens 30 to the light outlet 101 and covering the light outlet 101. When the user is taking a close-up shot, the user can toggle the toggle button 53 upward to cause the linkage 51 to rotate in the forward direction relative to the housing 10. The follower 52 can move downward along the height direction of the housing 10 as the linkage 51 rotates, thereby moving the diffuser lens 30 out of the light outlet 101.

[0071] The flashlight of the present application includes a housing, a light source, a diffusion lens, and a driving assembly. The light source is arranged corresponding to the light outlet on the housing. The diffusion lens is movably arranged on the housing, and the driving assembly can drive the diffusion lens to move relative to the housing, so that the diffusion lens can be relatively close to the light outlet and cover the light outlet or relatively far away from the light outlet and move out from the light outlet. The diffusion lens in the flashlight of the present application is integrated on the housing. The user can move the diffusion lens according to the shooting requirements to move it closer to or away from the light outlet. There is no need to install and disassemble the diffusion lens, and there is no need to store and carry the diffusion lens separately. It is more convenient and quick for users to use, and the user experience is effectively improved.
