Technical Field

[0001] This utility model belongs to the field of fill light technology, and specifically relates to a remote control device for a mobile phone camera flash. Background Technology

[0002] Currently, when using a mobile phone to find the right shooting angle, the resulting photos are sometimes not ideal due to lighting conditions. The current solution is to place an additional fill light to illuminate the subject, but this requires another person to set up the fill light, which is inconvenient. Utility Model Content

[0003] To address the aforementioned problems, the primary objective of this utility model is to provide a remote-controlled mobile phone camera flash control device, which solves the technical problem that photographers cannot simultaneously take photos with their mobile phones and use a fill light for illumination.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] This utility model provides a remote control device for a mobile phone camera flash, comprising a fill light mechanism and a remote control mechanism wirelessly connected to the fill light mechanism. The fill light mechanism includes a main body and a fill light section extending from one side of the main body. A fill light module, including a fill light lamp, is mounted on the fill light section. A first PCB board, electrically connected to the fill light module, is disposed inside the main body. A shutter button for controlling the mobile phone to take photos and controlling the fill light is provided on the upper surface of the remote control mechanism. A second PCB board, electrically connected to the shutter button, is disposed inside the remote control mechanism. The first PCB board and the second PCB board are wirelessly connected. Preferably, the fill light can be switched between modes; for example, the fill light can have two fill light modes: a normal power constant-on fill light mode and a high-power flash fill light mode. In the remote control device, the fill light mechanism is connected to the mobile phone. After the user sets the shooting angle of the mobile phone, the user presses the shutter button on the remote control mechanism, which then controls the fill light on the fill light mechanism to illuminate. Simultaneously, the remote control mechanism controls the fill light mechanism to send a shooting command to the mobile phone. Preferably, the remote control mechanism can be connected to the main body of the supplementary lighting mechanism by magnetic attraction.

[0006] Compared with existing technologies, the beneficial effects of this application are as follows: In the remote-controlled mobile phone camera flash control device, the supplementary lighting mechanism is connected to the mobile phone. After the user sets the shooting angle of the mobile phone, the user presses the shutter button on the remote control mechanism. The remote control mechanism then controls the supplementary lighting mechanism to turn on the supplementary light, and simultaneously controls the supplementary lighting mechanism to send a shooting command to the mobile phone. This allows for simultaneous mobile phone shooting and supplementary lighting functions, eliminating the need for another person to set the supplementary light, saving manpower and improving efficiency. It also solves the technical problem of poor shooting results due to the low power of the mobile phone's own supplementary light.

[0007] Furthermore, a zoom-in key and a zoom-out key are also provided on the upper surface of the remote control mechanism. Both the zoom-in key and the zoom-out key are electrically connected to the second PCB board.
