[0036] The hot shoe 10 is mounted on the camera body, and the on-camera flash 20 is detachably connected to the hot shoe 10 so that the on-camera flash 20 can be installed and removed from the hot shoe 10, and can be removed or installed as needed.

[0037] For ease of description and understanding, the direction facing inwards from the component is considered "inner," and the direction away from the component's interior is considered "outer." Figure 1 The placement shown is for reference only. The direction from which the on-camera flash 20 faces the hot shoe mount 10 is upward, and the direction from which the hot shoe mount 10 faces the on-camera flash 20 is downward.

[0038] Figure 3 This is a structural schematic diagram of the hot shoe mount 10 of this utility model from one perspective. Figure 4 This is a structural schematic diagram of the hot shoe mount 10 of this utility model from another perspective.

[0039] See Figures 1 to 3One end of the hot shoe 10 has an insertion part 101, which is used to insert into the corresponding structure of the on-camera flash 20 to connect the hot shoe 10 and the on-camera flash 20.

[0040] In this embodiment, the insertion part 101 is provided with a second conductive contact 102. After the insertion part 101 is inserted into the corresponding position on the on-camera flash 20, the second conductive contact 102 and the corresponding structure on the on-camera flash 20 abut against each other to transmit signals and current. A hot shoe circuit board is provided inside the hot shoe mount 10, and the second conductive contact 102 is electrically connected to the hot shoe circuit board.

[0041] In another embodiment, the hot shoe mount 10 is also provided with a hot shoe contact 103, which is electrically connected to the hot shoe circuit board. The hot shoe contact 103 is used to make contact with the corresponding contact on the camera body for signal and power transmission between the camera body and the hot shoe mount 10.

[0042] In this embodiment, the hot shoe contact 103 is disposed on the side of the hot shoe housing opposite to the second conductive contact 102. In other embodiments, the hot shoe contact 103 is disposed on any surface of the hot shoe housing.

[0043] Figure 5 This is an exploded view of the on-camera flash 20 of this utility model. Figure 6 This is a structural schematic diagram of the lamp holder 200 of this utility model.

[0044] See Figure 5 and Figure 6 The on-camera flash 20 includes a flash head 200 and a light conversion shield 300. The flash head 200 is used to emit light for illumination or fill light during shooting. The light conversion shield 300 is used to adjust and control the light emitted by the flash head 200 to obtain light of different intensities. The flash head 200 can be a structure made of materials such as silicone, plastic, or fabric.

[0045] A receiving groove 201 is provided on one side of the lamp holder 200. The receiving groove 201 is used to cooperate with the insertion part 101 on the hot shoe seat 10. The insertion part 101 can extend into and engage in the receiving groove 201, and the peripheral sidewall of the insertion part 101 abuts against the peripheral sidewall of the receiving groove 201.

[0046] In this embodiment, the receiving groove 201 is a rectangular groove, and the outer periphery of the insertion part 101 is a rectangular structure. After the insertion part 101 passes through the receiving groove 201, the peripheral sidewall of the insertion part 101 abuts against the peripheral sidewall of the receiving groove 201, thereby restricting the rotation of the lamp head 200 relative to the hot shoe.

[0047] The lamp holder 200 is provided with a first conductive contact 202, which is used to abut and connect with a second conductive contact 102 on the hot shoe 10 to form a circuit. The first conductive contact 202 is disposed in the receiving groove 201. After the insertion part 101 extends into the receiving groove 201, the first conductive contact 202 and the second conductive contact 102 come into contact, so that there is an electrical connection between the hot shoe 10 and the lamp holder 200.

[0048] In this embodiment, the first conductive contact 202 is disposed on the upper side wall of the receiving groove 201, and the second conductive contact 102 is disposed on the top of the insertion part 101. In other embodiments, the first conductive contact 202 is disposed on the peripheral side wall of the receiving groove 201, and the second conductive contact 102 is disposed on the peripheral side wall of the insertion part 101, with the positions of the first conductive contact 202 and the second conductive contact 102 corresponding to each other.

[0049] In some embodiments, a limiting hole 104 is provided on the peripheral sidewall of the insertion part 101, and a limiting protrusion 203 is provided in the receiving groove 201. After the insertion part 101 of the hot shoe 10 passes through the receiving groove 201, the limiting protrusion 203 can extend into the limiting hole 104 to restrict the separation between the lamp holder 200 and the hot shoe 10.

[0050] Figure 7 This is a cross-sectional structural diagram of the lamp holder 200 of this utility model.

[0051] See Figures 5 to 7 The lamp holder 200 contains a PCB board 210 and a lamp tube 220 for emitting light. The lamp tube 220 is used for emitting light, and the first conductive contact 202 is electrically connected to the PCB board 210.

[0052] In some embodiments, the light-emitting side of the lamp head 200 is provided with a light-transmitting opening (not shown in the figure), and the lamp tube 220 is provided corresponding to the light-transmitting opening, through which the light emitted by the lamp tube 220 is emitted outward. Further, a lens 230 is provided at the light-transmitting opening so that the light emitted by the lamp head 200 can pass through the lens 230. For example, the lens 230 is a Fresnel lens 230. The lamp head 200 is also provided with an indicator light 240 and a button 250.

[0053] In some embodiments, a first magnetic element 260 is provided on the light-emitting side of the lamp holder 200. A mounting groove 204 is formed on the light-emitting side of the lamp holder 200, the mounting groove 204 is close to the light-transmitting opening and is spaced apart from the light-transmitting opening; the first magnetic element 260 is installed in the mounting groove 204.

[0054] In another embodiment, the first magnetic element 260 is directly attached to the light-emitting side of the lamp holder 200. In other embodiments, the first magnetic element 260 is disposed inside the lamp holder 200.

[0055] In some embodiments, the first magnetic element 260 is installed in the mounting groove 204, and the end of the first magnetic element 260 facing the light conversion cover 300 does not extend beyond the light-emitting side of the lamp head 200, so that the setting of the first magnetic element 260 will not affect the external dimensions of the lamp head 200, and will not affect the packaging and transportation of the lamp head 200.

[0056] In one embodiment, the end of the first magnetic element 260 facing the light conversion cover 300 is flush with the side of the light-emitting side.

[0057] In another embodiment, one end of the first magnetic element 260 facing the light conversion cover 300 is located inside the lamp head 200 and is spaced apart from the light-emitting side.

[0058] Figure 8 This is a schematic diagram of the structure of the light conversion cover 300 of this utility model. Figure 9 This is a cross-sectional structural diagram of the light conversion cover 300 of this utility model.

[0059] See Figures 1 to 9 The light conversion cover 300 can convert light. The light conversion cover 300 forms an opening 301 on one side, which is fitted against the light-emitting side of the flash head 200, covering the light-transmitting port. Light emitted from the light-transmitting port of the flash head 200 is converted by the light conversion cover 300, resulting in new lighting effects, thus enabling the on-camera flash 20 to obtain more light and provide a wider lighting environment. The opening 301 of the light conversion cover 300 covers the light-transmitting port to ensure that more light emitted from the light-transmitting port can enter the light conversion cover 300 for conversion.

[0060] In some embodiments, a first magnetic element 260 is provided on the light-emitting side of the lamp head 200, and a second magnetic element 310 is provided on the light conversion cover 300. The second magnetic element can magnetically attract the first magnetic element 260, so that the open side of the light conversion cover 300 can be brought into contact with the light-emitting side of the lamp head 200, and the opening 301 covers the light-transmitting opening. The light conversion cover 300 is magnetically secured to the lamp head 200, facilitating quick installation and replacement of the light conversion cover 300.

[0061] The end of the second magnetic component 310 facing the lamp head 200 does not extend beyond the open side of the light conversion cover 300, so as to facilitate the adhesion of the open side of the light conversion cover 300 to the light-emitting side of the lamp head 200.

[0062] In one embodiment, the light conversion cover 300 has an opening 302 on its open side, and the second magnetic element 310 is installed in the opening 302. The direction of the opening 301 of the opening 302 is the same as the direction of the opening 301 on the light conversion cover 300.

[0063] In one embodiment, the light conversion cover 300 does not have an installation port 302, and the first magnetic component 260 is fixed to the light conversion cover 300 by bolts or snap-fitting.

[0064] The plane containing the open side of the light conversion cover 300 is parallel to the plane containing the light-emitting side of the lamp head 200. When the open side of the light conversion cover 300 is attached to the light-emitting side of the lamp head 200, light leakage between the open side of the light conversion cover 300 and the light-emitting side of the lamp head 200 is effectively prevented.

[0065] In one embodiment, the light-emitting side of the lamp head 200 has a groove that surrounds the light-transmitting opening. The open side of the light conversion cover 300 is attached to the sidewall of the groove, and the outer periphery of the light conversion cover 300 abuts against the sidewall of the groove, thereby further positioning and limiting the light conversion cover 300 on the lamp head 200, ensuring the stability and reliability of the upper limit position of the light conversion cover 300 on the lamp head 200.

[0066] In another embodiment, the light-emitting side of the lamp head 200 has a locking hole, and the open side of the light conversion cover 300 has a protruding locking protrusion. The locking protrusion can extend into and engage with the locking hole to position and limit the light conversion cover 300 on the lamp head 200.

[0067] In another embodiment, a first magnetic element 260 is disposed within a mounting groove 204 of the lamp holder 200. One end of the first magnetic element 260 facing the light conversion cover 300 is located within the mounting groove 204 and is spaced from the light-emitting side of the lamp holder 200. A protruding structure is formed on the light conversion cover 300, which passes through the mounting groove 204 for positioning between the light conversion cover 300 and the lamp holder 200.

[0068] It should be noted that multiple light conversion covers 300 can be configured, and each light conversion cover 300 can have different adjustment effects to adapt to different lighting needs. Multiple light conversion covers 300 can be installed on the lamp head 200 respectively.

[0069] In one embodiment, a light outlet is provided on one side of the light conversion mask 300, and a diffuser is provided at the light outlet. The light conversion mask 300 is a diffuser. The diffuser is made of a special material that can effectively soften light, reduce light intensity and reduce shadows, making the light softer and more natural, thereby achieving a more natural effect.

[0070] In another embodiment, a light outlet is provided on one side of the light conversion cover 300, and a light-blocking plate is provided at the light outlet. The light-blocking plate is used to block light and is also made of metal or cardboard, with its surface covered with light-blocking material. It can block light and achieve effects such as reducing brightness and adjusting shadows.

[0071] In some embodiments, a light outlet is provided on one side of the light conversion cover 300, and a reflector is provided inside the light conversion cover 300, the light path of the reflector being able to pass through the light outlet. The reflector can reflect light, increasing the brightness and intensity of the light, making the subject brighter and its outline clearer. The light shield, on the other hand, can block light, reduce the light intensity, adjust the ratio of shadows and light, and make the photo softer.

[0072] In other embodiments, the light conversion cover 300 is a softbox structure with a light outlet on one side, and the inner diameter of the softbox gradually increases in the direction towards the light outlet. The softbox can make the light softer and more uniform, reduce the contrast of the light, and thus make the subject appear more delicate.
