[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3This quick-release magnetic ring polarized flash unit includes an inner ring 10 and an outer ring 20. The inner ring 10 and outer ring 20 are magnetically connected for easy disassembly and installation. A convex block 101 is fixedly installed on the outer side of the inner ring 10, and a magnetic block 102 is embedded in the inner wall of the convex block 101. A lamp head retainer 103 is fixedly installed on the inner wall of the inner ring 10. The inner ring 10 can be detachably installed with an external ring flash unit, such as the Godox AR400 macro ring flash unit. Conventional outer ring designs use screws for fixing. If the flash frequency is too high, the lamp tube may overheat. If the outer ring cannot be easily removed, it will affect the heat dissipation speed of the lamp tube. The detachable outer ring achieves a heat dissipation effect.

[0021] The inner ring 10, the convex block 101, and the lamp holder strip 103 are integrally formed and are all 3D printed using high-strength nylon material. Compared with ordinary 3D materials, they have stronger high temperature resistance and wear resistance.

[0022] Please see Figure 1-3 An outer plate 203 is fixedly mounted on the surface of the outer ring 20. A fan-shaped hole 207 is formed on the surface of the outer plate 203. A central ring 204 is fixedly mounted on the inner wall of the outer plate 203 for fitting around the outside of the lens. A second convex block 201 is fixedly mounted on the outer wall of the outer ring 20. A second magnetic block 202 is embedded inside the second convex block 201. The outer ring 20 is detachably mounted to the inner ring 10 via the first magnetic block 102 and the second magnetic block 202. The outer ring 20 and the interconnecting structures are also 3D printed using high-strength nylon material.

[0023] Please see Figure 1-3 The outer ring 20 has an outer limit block 206 arranged in a ring fixedly installed on its inner wall, and the inner limit block 205 is fixedly installed on the outer wall of the central ring 204. A positioning strip 208 is fixedly installed on the outer wall of the central ring 204 between the two inner limit blocks 205. The inner walls of the outer ring 20 and the outer plate 203 are fitted with polarizing lenses by the inner limit blocks 205 and the outer limit blocks 206. The polarizing lenses are restricted to be installed on the outer wall of the central ring 204 by the positioning strip 208.

[0024] Working principle: In use, the inner ring 10 is engaged with the external ring flash unit via the lamp head retainer 103, and the outer ring 20 is magnetically attached to the inner ring 10 via magnet 102 and magnet 202. This process achieves quick-release and convenient magnetic installation of the inner ring 10, outer ring 20, and ring flash unit. Simultaneously, opening the outer ring 10 allows for heat dissipation of the flash tube.

[0025] A polarizing lens is detachably installed in the space formed by the outer ring 20, the outer plate 203 and the central ring 204. The inner limiting block 205, the outer limiting block 206 and the positioning strip 208 can restrict the polarizing lens to ensure that the polarizing lens will not rotate or fall off. The polarizing lens can eliminate the highlights formed by the object during shooting.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
