[0025] (1)Circuit assembly is connected with mobile phone through data line, one end of data line is connected to mobile phone Type-C interface or other interface, and the other end is connected to control module in circuit assembly. Circuit assembly realizes signal amplification and triggering through triode and oscillation circuit. When mobile phone sends shooting instruction, or second shooting key 41 sends shooting instruction, synchronous signal is transmitted to control module of flash through data line, and flash tube is triggered to discharge and flash.

[0028] Referring to the accompanying Figure 1 and the accompanying Figure 2 , a synchronous flash that can be clamped on a mobile phone and assist the mobile phone in shooting is provided, which comprises a clamp seat 2 and a movable part 3 that can elastically move on the clamp seat 2, and the clamp seat 2 and the movable part 3 can be telescopic to clamp the mobile phone; specifically, the clamp seat 2 is internally provided with a cavity for the movable part 3 to slide therein, and the movable part 3 is fixedly connected with a sliding rod 31, one end of the sliding rod 31 away from the movable part 3 is fixedly connected with a limiting part 32, and the cavity is internally provided with an elastic member 30 matched with the limiting part 32, the elastic member 30 can provide elastic force to reset the movable part 3, so as to realize reliable clamping of the mobile phone by the movable part 3 and the clamp seat 2.

[0029] In the present example, the Bluetooth connection mode can be used to interconnect the device and the mobile phone, and the power supply mode of the device can be independent power supply as mentioned above, or the device can be connected with the mobile phone through a data line, and the mobile phone can supply power to the device.

[0030] Preferably, the light emitter 11 and the clamp seat 2 in the clamping part are detachably connected, as an embodiment, specifically: the body 1 is fixedly connected with a screw rod 14, and the clamp seat 2 is provided with a screw hole 21 matched with the screw rod 14, and the body 1 and the clamping part can be detachably connected through the threaded connection. In addition, the detachable connection between the body 1 and the clamping part can also be achieved through clamping, magnetic attraction and other ways. Since clamping and magnetic attraction are relatively common connection modes in the industry, they will not be described here.

[0031] Preferably, the body 1 is provided with a plurality of first buttons 13 for controlling the working mode (turning on / off, color temperature, light intensity adjustment) of the light emitter 11; the first buttons 13 are arranged on the body 1 and on the same side as the light emitter 11. Light of different color temperatures is emitted by the light emitter 11, and different color temperature light is mixed by adjusting the brightness ratio of different color LEDs. For example, by using a combination of warm and cold LEDs, the color temperature can be adjusted by adjusting the brightness ratio of the LEDs. The circuit assembly is provided with a microcontroller for receiving button signals and controlling the brightness of the LEDs. The microcontroller adjusts the driving current of different color LEDs according to the button input, thereby changing the color temperature. That is, the first buttons 13 are connected to the microcontroller in the circuit assembly by wires, and the principle is prior art, which will not be described here.

[0032] Preferably, the body 1 is provided with an indicator light 12 for indicating the working state (light intensity display, color temperature display light).

[0033] Preferably, the body 1 is detachably connected to a control body 4, and the control body 4 is provided with a second button 41. As an embodiment, specifically: the detachable connection between the control body 4 and the body 1 is achieved by clamping connection through a dismounting part 10. The dismounting part 10 is fixedly connected to the body 1, and the dismounting part 10 is provided with a sliding groove, and the control body 4 is provided with a sliding block matched with the sliding groove, and the sliding block can be clamped and slid in the inside of the dismounting part 10. Thus, the detachable connection between the body 1 and the control body 4 is achieved.

[0034] Preferably, the technical solution is divided into three modes (product styles) in design and implementation:

[0035] Embodiment 1

[0036] The basic version is a light emitter 11 flash mode controlled by a mobile phone. After the device and the mobile phone are installed, the signal interconnection between the device and the mobile phone can be realized by Bluetooth or data line. When the mobile phone is used for shooting (by pressing the shooting key on the mobile phone camera software), the light emitter 11 of the device is controlled to flash synchronously.

[0037] Embodiment 2

[0038] The enhanced version is a light emitter 11 flash control mode controlled by a mobile phone and a control body 4. After the device and the mobile phone are installed, the mobile phone shooting control can be remotely performed by the control body 4 with wireless signal connection. The signal interconnection between the mobile phone and the device can make the control body 4, the light emitter 11 and the mobile phone synchronous when shooting, thereby satisfying better shooting effect.

[0039] Embodiment 3

[0040] The handle version is based on the basic version and the enhanced version, and a handle is added for the user to hold. The handle is integrally connected with the body 1 and / or the connecting part.Figure 3 The handle is integrally connected with the body 1, and the control body 4 is detachably connected on the handle; the illuminant 11 of the embodiment is arranged on the body 1. The control body 4 can control the mobile phone to take a photo, and can also control the illuminant 11 to flash and extinguish to take a photo.

[0041] The second button 41 can be a photo key, and the control body 4 has circuit components capable of signal transmission and other cooperation in function with the mobile phone and the body 1. The second button 41 can be interconnected with the mobile phone to control the photo function of the mobile phone, that is, the signal interconnection between the mobile phone and the circuit components can realize one-way or two-way control of the mobile phone to take a photo. The photo function of the mobile phone can be linked with the illuminant 11 on the body 1 to control the flash.

[0042] Therefore, the device can not only take a photo by hand, but also can be detached from the control body 4 to control the mobile phone to take a photo by the second button 41.

[0043] Therefore, the device effectively solves the limitation problem of the mobile phone flash in the scene of insufficient natural light and backlight. The device can trigger the illuminant 11 to flash when the mobile phone sends a flash instruction through the data line or Bluetooth module, ensuring the precise cooperation of the light supplement and the shooting action. Through the independent power supply or the mobile phone power supply mode, the device can be used flexibly in different scenes, avoiding the insufficient light supplement effect caused by the internal space limitation of the mobile phone. The first button 13 further enhances the operability, so that the user can quickly adjust the color temperature and light intensity in complex light conditions, thereby significantly improving the photo quality.

[0044] In summary, the device solves the limitation of the photo light when the mobile phone flash is insufficient through the design of the external flash, and provides more diversified shooting experience for users through the flexible adjustment function and the portability design.
