[0018] A circulation pump body 32 is also included, and the output end and the input end of the circulation pump body 32 are communicated with the medium flow channel 31 .
[0019] The lampshade 1 further comprises heat dissipation fins 4 , which are fixedly connected to the four sides of the lampshade 1 , and the inner sides of the heat dissipation fins 4 are in contact with the lighting device 2 . The heat dissipation fins 4 are designed in a grid-shaped hollow shape to ensure ventilation and heat dissipation of the lighting device 2 .
[0020] When the heat generated by the lighting device 2 is transferred to its back side, the heat can be quickly and timely transferred to the lower end of the heat transfer column 34, and then transferred to the overall structure of the heat transfer column 34.
