DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0031] Please refer to Figures 1-6 A ring-shaped soft light for photography comprises an annular assembly seat 1, an annular lampshade 2 and an annular circuit board 3 fixedly installed on the annular assembly seat 1. The annular assembly seat 1 is provided with an annular assembly groove 11. Heat dissipation through holes 12 extending to the outer wall of the annular assembly seat 1 are uniformly arranged on both sides of the annular assembly groove 11. The annular circuit board 3 is fixedly installed on the top of the annular assembly groove 11 and arranged on the inner side of the annular lampshade 2. The upper surface of the annular circuit board 3 is electrically connected with uniformly arranged LED lamp beads 31. The lower surface of the annular circuit board 3 is fixedly connected with heat dissipation fins 32 uniformly arranged in the annular assembly groove 11. The heat dissipation fins 32 are arranged obliquely to the diameter direction of the annular circuit board 3.

[0032] The tilt angle adjusting assembly 4 is assembled outside the annular assembly seat 1, and comprises an upper hinge seat 41, a connecting seat 42, a self-locking mechanism 43, and a fixed combination of a lower hinge seat A 44 and a lower hinge seat B 45. The upper hinge seat 41 is fixed to the annular assembly seat 1 and is hingedly connected to the lower hinge seat A 44. The lower hinge seat B 45 is fixedly connected to the connecting seat 42 at the bottom. The self-locking mechanism 43 is assembled on the upper hinge seat 41 and the lower hinge seat B 45.

[0033] The annular assembly seat 1 can ensure stable installation of the annular lampshade 2 and the annular circuit board 3 thereon. The annular lampshade 2 covers the outside of the annular circuit board 3 and the LED lamp beads 31 and is made of materials such as acrylic or polycarbonate with sanding or sandblasting treatment on the surface. The annular lampshade 2 can scatter the light emitted by the LED lamp beads 31 and uniformly distribute the light to provide uniform and soft lighting and reduce glare and shadows.

[0034] The annular assembly groove 11 can ensure stable installation of the annular circuit board 3 on the annular assembly seat 1 and effectively accommodate the heat dissipation fins 32. The heat dissipation fins 32 can be in an arc structure or a linear structure deviating from the diameter direction of the annular circuit board 3. When the annular soft light lamp is arranged at a specific angle, the heat dissipation fins 32 of this design structure all present a posture of one end being high and the other end being low. After the flowing air from the outside enters the annular assembly groove 11 through the heat dissipation through holes 12 on one side, the air exchanges heat with the heat dissipation fins 32. After the temperature rises, the air density decreases and is discharged from the heat dissipation through holes 12 on the upper side. Air with a lower temperature is supplemented to the annular assembly groove 11 from the heat dissipation through holes 12 on the lower side. In this way, the heat dissipation effect of the annular circuit board 3 is effectively improved, thereby ensuring the continuous and stable operation of the annular soft light lamp.

[0035] The tilt angle adjusting assembly 4 can synchronously adjust the tilt angle of the annular assembly seat 1 and the annular lampshade 2 and the annular circuit board 3 assembled thereon. The connecting seat 42 can be nested and inserted into a triangular support or other types of positioning structures. When the upper hinge seat 41 is rotated in the lower hinge seat A 44 and the lower hinge seat B 45, the tilt angle can be quickly adjusted. After the tilt angle adjustment is completed, the self-locking assembly can be used for locking and positioning to avoid invalid rotation of the annular soft light lamp during operation and affect the lighting effect during the photography process.

[0036] To ensure that the annular lampshade 2 and the annular circuit board 3 can be stably installed on the annular assembly seat 1, the following technical solutions are provided.

[0037] The annular assembly seat 1 is fixedly connected with annular wing seats 13 on the inner and outer sides. The annular lampshade 2 and the annular circuit board 3 are fixedly connected to the annular wing seats 13 through positioning bolts 14.

[0038] In the assembly process, firstly, the annular circuit board 3 is installed, the positioning bolts 14 are screwed from top to bottom to the annular wing seat 13 to fix the annular circuit board 3, and then the annular lampshade 2 is installed, the annular lampshade 2 is sleeved on the annular assembly seat 1, and the positioning bolts 14 are screwed from bottom to top to the annular lampshade 2 to fix and install the annular lampshade 2.

[0039] A thickened grommet 21 is arranged at the interface of the annular lampshade 2, which can ensure that the corresponding positioning bolt 14 is screwed and fixed at the position of the grommet 21.

[0040] In order to ensure that the connecting seat 42 can be assembled with a triangular support or other types of positioning structure, and ensure that the lower hinge seat A 44 and the lower hinge seat B 45 can be fixed and combined, the following technical solutions are provided.

[0041] The bottom of the connecting seat 42 is provided with an assembly slot 421, and the side wall of the lower hinge seat A 44 is provided with a fixing bolt 441 which is screwed with the lower hinge seat B 45.

[0042] The assembly slot 421 can be inserted and combined with the triangular support to realize the fixed installation of the annular soft light lamp, and the annular soft light lamp can be conveniently disassembled from the triangular support.

[0043] The lower hinge seat A 44 and the lower hinge seat B 45 can be fixed and combined by two groups of side-by-side arranged fixing bolts 441, which facilitates the disassembly and assembly of the two, so as to realize the disassembly and assembly operation of the upper hinge seat 41 and the self-locking mechanism 43.

[0044] In order to ensure that the self-locking mechanism 43 can be stably assembled and realize the functions of adjusting the inclination angle and self-locking, the following technical solutions are provided.

[0045] The self-locking mechanism 43 comprises a supporting spring 431, a pin shaft B 432, a spline shaft A 433, an end face gear A 434, an end face gear B 435 and an adjusting knob 436. The pin shaft B 432, the end face gear A 434 and the spline shaft A 433 are concentrically and sequentially fixed. The pin shaft B 432 is assembled on the lower hinge seat B 45. The adjusting knob 436 is fixedly installed on the end of the pin shaft B 432 and arranged outside the lower hinge seat B 45. The spline shaft A 433 is slidably inserted with the upper hinge seat 41. The supporting spring 431 is arranged outside the spline shaft A 433 and abuts with the upper hinge seat 41 and the end face gear A 434 at both ends. The end face gear B 435 is fixedly connected to the lower hinge seat B 45 and engaged with the end face gear A 434.

[0046] The support spring 431 can push the pin shaft B 432, the end face gear A 434 and the spline shaft A 433 to the lower hinge base B 45 side in a natural state, so as to realize the meshing locking of the end face gear A 434 and the section gear B, and the end face gear A 434 and the spline shaft A 433 are locked to limit the rotation of the end face gear A 434 due to the limiting action of the end face gear B 435 fixed to the lower hinge base B 45. Since the spline shaft A 433 is in sliding insertion with the upper hinge base 41, the upper hinge base 41 and the annular assembly seat 1 fixed to the upper hinge base 41 can be locked and positioned at the same time.

[0047] When the inclination angle of the annular soft light lamp needs to be adjusted, the adjusting knob 436 can be manually pressed to drive the pin shaft B 432, the end face gear A 434 and the spline shaft A 433 to move to the lower hinge base A 44 side. The support spring 431 is in a compressed state and the end face gear A 434 is in a state of separation and cancellation of locking with the end face gear B 435. At this time, the inclination angle can be quickly adjusted by rotating the adjusting knob 436 or directly rotating the annular assembly seat 1. After the inclination angle adjustment is completed, the action on the adjusting knob 436 is cancelled, and the end face gear A 434 is re-engaged with the end face gear B 435 under the action of the support spring 431.

[0048] In order to ensure that the upper hinge base 41 can be stably installed in a relative rotation mode and realize the matching combination with the lower hinge base A 44, the support spring 431 and the spline shaft A 433, the following technical solutions are provided.

[0049] The upper hinge base 41 is fixed with a pin shaft A 411 which is in rotational connection with the lower hinge base A 44. The upper hinge base 41 is provided with a spline groove A 412 which is in sliding insertion with the spline shaft A 433. The upper hinge base 41 is provided with a positioning ring groove 413 which is arranged outside the spline groove A 412, and the support spring 431 is nested and abuts to the positioning ring groove 413.

[0050] The arrangement of the pin shaft A 411 can ensure that the upper hinge base 41 is in rotational connection with the lower hinge base A 44. The arrangement of the spline groove A 412 can realize the sliding insertion with the spline shaft A 433. The arrangement of the positioning ring groove 413 can ensure the stability of the installation of the support spring 431.

[0051] In order to ensure that the adjusting knob 436 can be fixedly installed on the outside end of the pin shaft B 432, the following technical solutions are provided.

[0052] The adjusting knob 436 is fixed with a spline shaft B 4361 at the shaft center. The pin shaft B 432 is provided with a spline groove B 4321 which is in sliding insertion with the spline shaft B 4361 at the shaft center. The adjusting knob 436 is assembled with an assembly bolt 4362 which is in rotational connection with the pin shaft B 432 at the shaft center.

[0053] The adjusting knob 436 is detachably mounted to the pin shaft B432 through the spline shaft B4361 and the mounting bolt 4362, and when the self-locking mechanism 43 is mounted on the upper bracket 41 and the lower bracket B45, the installation of the pin shaft B432, the spline shaft, the face gear A434 and the supporting spring 431 is completed first, and then the adjusting knob 436 is fixedly mounted, so that the installation of the pin shaft B432 is not interfered by the adjusting knob 436.
