[0026] like Figure 1 and Figure 2 As shown, a COB lampshade 11 with a protective opening structure that is easy to disassemble and assemble has a convenient disassembly and assembly method and a small assembly volume, which is convenient for photographers to carry and store. The protective opening structure of this embodiment includes a lampshade assembly 1 and a base assembly 2 arranged on the COB light source 3, wherein the lampshade assembly 1 can be connected to the COB light source 3 through the base assembly 2 for use, and the base assembly 2 can also be connected to other photographic accessories, and has a wide range of applications.

[0027] like Figure 2 As shown, the lampshade assembly 1 of the present embodiment includes a COB lampshade 11 and a connecting bracket 12 connected to the bottom of the COB lampshade 11, and the base assembly 2 includes a bottom plate 21 arranged on the COB light source 3 and surrounding the column COB light source 3, and a fixed base 22 connected to the bottom plate 21, wherein the connecting bracket 12 is screwed and engaged with the base assembly 2, so that the connecting bracket 12 can be plugged in and rotated to be screwed on the fixed base 22, so that the COB lampshade 11 connected to the connecting bracket 12 is fixed above the fixed base 22, thereby realizing the quick connection between the COB lampshade 11 and the COB light source 3, and the installation method is convenient; and when disassembling, the connecting bracket 12 can be rotated in the opposite direction to realize the separation of the connecting bracket 12 and the fixed base 22, thereby realizing the quick disassembly of the COB lampshade 11 and the COB light source 3, and the disassembly method is convenient for photographers to use.

[0028] A limiting mechanism is also provided at the engaging position between the connecting bracket 12 and the fixed base 22 of this embodiment, so that when the connecting bracket 12 and the fixed base 22 are screwed together and engaged, the gap at the connecting position can be filled under the action of the limiting mechanism, thereby improving the stability of the connection between the COB lampshade 11 and the COB light source and improving the photographer's user experience.

[0029] Specifically, Figure 2 and Figure 3 As shown, a groove body is provided at the bottom of the connecting bracket 12 of this embodiment. After the connecting bracket 12 is connected to the fixed base 22, the fixed base 22 can be embedded in the groove body to achieve stable installation; and, three clamping blocks 121 are equidistantly provided on the inner wall of the bottom of the connecting bracket 12 of this embodiment, and three L-shaped clamping grooves 221 are equidistantly provided on the outer peripheral side wall of the fixed base 22. When the connecting bracket 12 is connected to the fixed base 22, each clamping block 121 is respectively clamped into each L-shaped clamping groove 221 to achieve quick installation of the COB lampshade 11 and the COB light source 3.

[0030] Specifically, the L-shaped slot 221 of the present embodiment includes a vertical section connected to the top surface of the fixed base 22 and a horizontal section connected to the vertical section and connected to the bottom surface of the fixed base 22. When the connecting bracket 12 is connected to the fixed base 22, the clamping block 121 at the inner wall of the connecting bracket 12 is vertically inserted along the vertical section of the L-shaped slot 221, and is rotated to be clamped to the horizontal section of the L-shaped slot 221 for locking. The connection method is convenient. At the same time, when disassembling, it is only necessary to rotate the connecting bracket 12 or the fixed base 22 to disengage the clamping block 121 from the horizontal section of the L-shaped slot 221 to the vertical section, so that it can be directly separated. The disassembly method is convenient, thereby realizing the quick disassembly and assembly of the COB lampshade 11 and the COB light source of the present embodiment.

[0031] like Figure 3 As shown, the limiting mechanism of this embodiment includes a limiting block 4 and a positioning bead 5, wherein the L-shaped slot 221 forms a limiting block 4 at the corner where the horizontal section and the vertical section are connected, and the bottom end face of the limiting block 4 is provided with a limiting hole connected to the horizontal section. When the positioning bead 5 is installed in the limiting hole, the bottom of the positioning bead 5 extends into the horizontal section, so that when the clamping block 121 is inserted along the vertical section of the L-shaped slot 221 and rotated to be clamped into the horizontal section, the positioning bead 5 can resist the top surface of the clamping block 121, so that the connecting bracket 12 is forced to be tightly attached to the fixed base 22 as a whole, thereby filling the connecting gap between the connecting bracket 12 and the fixed base 22, ensuring that the two can remain stable after connection, thereby achieving the stability of the COB lampshade 11 and the COB light source 3 after connection.

[0032] In order to improve the connection strength between the COB lampshade 11 and the COB light source and prevent the connecting bracket 12 or the fixed base 22 from rotating and disengaging, the present embodiment also provides a self-locking component 6 at the outer periphery of the connecting bracket 12, so that when the connecting bracket 12 is vertically inserted into the L-shaped slot 221 through the clamping block 121 and rotated and clamped on the fixed base 22, the self-locking component 6 can automatically clamp in the vertical section of the L-shaped slot 221 to lock the connection between the connecting bracket 12 and the fixed base 22, thereby effectively preventing the COB lampshade 11 from rotating and disengaging.

[0033] Specifically, Figures 1 to 4 As shown, a mounting groove 122 is provided at a position corresponding to any one of the clamping blocks 121 on the outer periphery of the connecting bracket 12 of this embodiment, and a self-locking opening 123 is provided at the front end of the mounting groove 122 which penetrates into the connecting bracket 12 and corresponds to the vertical section of the L-shaped groove. The self-locking component 6 of this embodiment is arranged in the mounting groove 122, and when the connecting bracket 12 is connected to the fixed base 22, the front end of the self-locking component 6 can follow the rotation of the connecting bracket 12 and be clamped in the vertical section of the L-shaped clamping groove 221 through the self-locking opening 123, thereby limiting the rotation of the connecting bracket 12 and preventing the COB lamp cover 11 from automatically rotating and disengaging.

[0034] like Figure 2and Figure 4 As shown, the self-locking component 6 of this embodiment includes a self-locking button 61 and a self-locking spring 62, a connecting column is vertically arranged in the installation groove 122, and the middle part of the self-locking button 61 is rotated and plugged on the connecting column, so as to be arranged in the installation groove 122; the front end of the self-locking button 61 of this embodiment corresponds to the position of the self-locking port 123, and the self-locking button 61 can be rotated through the connecting column under the action of the self-locking spring 62 so that its front end is clamped in the self-locking port 123 or detached from the self-locking port 123; in order to realize that when the connecting bracket 12 is connected to the connecting base, the front end of the self-locking button 61 automatically passes through the self-locking port 123 and is clamped in the L-shaped slot 221, a self-locking slot 124 is arranged at the rear end of the installation groove 122 of this embodiment, and the self-locking spring 62 is arranged in the self-locking slot 12 4 and the front end of the self-locking spring 62 abuts against one side of the rear end of the self-locking button 61. The rear end of the self-locking button 61 is away from the mounting groove 122 under the action of the self-locking spring 62, and the front end of the self-locking button 61 is rotated through the middle connecting column to penetrate into the self-locking opening 123, so that when the connecting bracket 12 and the fixed base 22 are rotated and engaged, the self-locking button 61 can automatically pass through the self-locking opening 123 under the action of the self-locking spring 62 and be engaged in the vertical section of the L-shaped slot 221; when the COB lampshade 11 is disassembled, it is only necessary to press the rear end of the self-locking button 61 to compress the self-locking spring 62, so that the front end of the self-locking button 61 is disengaged from the L-shaped slot 221 and exits the self-locking opening 123, so that the rotation of the connecting bracket 12 can be unlocked, thereby realizing the disassembly of the COB lampshade 11.

[0035] like Figure 2 and Figure 3 As shown, the fixed base 22 of this embodiment is also provided with an external thread at the periphery, and the inner wall of the connecting bracket 12 (not shown in the figure) is also provided with an internal thread, so that the COB lampshade 11 can also be connected to the COB light source 3 by threaded connection between the connecting bracket 12 and the fixed base 22, which makes disassembly and assembly more convenient and the connection more secure.

[0036] like Figure 2 As shown, the connecting bracket 12, the fixed base 22 and the bottom of the lampshade of this embodiment are all provided with light-transmitting openings, and a mounting opening 211 for mounting the COB light source 3 is provided at a position corresponding to the base and the light-transmitting opening, so that when the CPB lampshade is connected to the COB light source 3, the light emitted by the COB light source 3 can be emitted through the mounting opening 211 and the light-transmitting opening.

[0037] In summary, the working principle of the present embodiment is as follows: the present embodiment sets a connecting bracket 12 at the bottom of the COB lampshade 11, and sets a fixed base 22 adapted to the connecting bracket 12 on the COB light source 3, so that the COB lampshade 11 can be connected to the COB light source 3 by means of a screwing and snap-fitting connection between the connecting bracket 12 and the fixed base 22, and the connection method is convenient and easy to disassemble; at the same time, the present embodiment sets a limiting mechanism between the connecting position of the connecting bracket 12 and the fixed base 22. After the COB lampshade 11 and the COB light source 3 are connected through the connecting bracket 12 and the fixed base 22, the limiting mechanism can limit the connection between the connecting bracket 12 and the fixed base 22, thereby avoiding loosening of the connection wires between the two, thereby improving the stability of the connection between the COB lampshade 11 and the COB light source 3.

[0038] The embodiments described above are only preferred implementation modes of the present utility model and cannot be used to limit the protection scope of the present utility model. Any non-substantial changes and modifications made by technicians in this field on the basis of the utility model shall fall within the protection scope of the present utility model.
