[0022] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] See also Figure 1 A high-voltage electromagnetic shielding light box is arranged on a shielding floor 4, and the shielding floor 4 is formed with a light box installation port. The shielding light box includes: a shielding box 5 arranged at the light box installation port, and a light-transmitting port is formed at the bottom of the shielding box 5, and the bottom of the shielding box 5 is flush with the bottom of the shielding floor 4; a ventilation waveguide window 1 installed on the top of the shielding box 5, and a conductive lining is arranged between the ventilation waveguide window 1 and the shielding box 5; and a lamp 2 arranged in the shielding box 5.

[0024] In the utility model, a preferred implementation is: the shielding box 5 is arranged on the shielding floor 4, and the lamp 2 is installed in the shielding box 5. The shielding box 5 and the shielding floor 4 are made of the same material to ensure the continuation of the anti-radiation performance. By arranging a ventilation waveguide window 1 in the shielding box 5, it is ensured that during the use of the lamp 2, the heat generated by the lamp 2 cannot be discharged, which causes the structure of the lamp 2 and the shielding box 5 to be easily damaged, thereby causing the shielding property to deteriorate. The conductive lining can ensure that electromagnetic leakage does not occur near the installation position of the ventilation waveguide window 1.

[0025] Furthermore, a hanging rod 21 is connected between two inner walls of the shielding box 5 that are arranged opposite to each other, a hanging rod 22 is fixedly installed at the bottom of the hanging rod 21, and the lamp 2 is fixedly installed at the bottom of the hanging rod 22. The hanging rod 21 and the hanging rod 22 are used to prevent the lamp 2 from being directly arranged on the inner wall of the shielding box 5, thereby preventing the lamp 2 from being directly installed in the shielding box 5, and requiring a corresponding installation structure to be arranged in the shielding box 5, which causes the structure in the shielding box 5 to be damaged, thereby reducing the shielding effect.

[0026] Furthermore, the shielding floor 4 and the shielding box 5 are fixedly connected by welding. Preferably, the shielding floor 4 and the shielding box 5 are connected by full welding using carbon dioxide gas shielded welding.

[0027] Further, the ventilation waveguide window 1 is fixedly connected by bolts 11. The connection by the bolts 11 facilitates the disassembly or installation of the ventilation waveguide window 1, thereby facilitating the subsequent installation and maintenance of the lamp 2.

[0028] Furthermore, the shielding box 5 is provided with a metal gasket at the fixing position corresponding to the bolt 11. The metal gasket is used to prevent radiation from overflowing from the bolt 11 position.

[0029] Furthermore, a plurality of metal washers are provided, and the plurality of metal washers are oppositely arranged at two ends of the bolt 11 .

[0030] Furthermore, the shielding floor slab 4 is a microporous shielding wave sound-absorbing panel.

[0031] Furthermore, a filter 3 is installed on the side of the shielding box 5. The filter 3 is arranged inside the shielding box 5 to eliminate the specific frequency in the shielding box 5. Preferably, the power line of the lamp 2 is connected through the filter 3 to effectively filter out the frequency point of the specific frequency required by the high voltage electromagnetic shielding laboratory in the power line or the frequency other than the frequency point.

[0032] Furthermore, the shielding box 5 is made of galvanized steel plate.

[0033] Furthermore, the width of the lamp 2 is adapted to the width of the light-transmitting opening.

[0034] The following is an explanation of the use process of the high-voltage electromagnetic shielding light box of the utility model.

[0035] The shielding box 5 is arranged on the shielding floor 4, and the lamp 2 is installed in the shielding box 5. The shielding box 5 and the shielding floor 4 are made of the same material to ensure the continuation of the anti-radiation performance. The ventilation waveguide window 1 is arranged in the shielding box 5 to ensure that during the use of the lamp 2, the heat generated by the lamp 2 cannot be discharged, which will cause the structure of the lamp 2 and the shielding box 5 to be easily damaged, thereby causing the shielding property to deteriorate. The conductive lining can ensure that electromagnetic leakage will not occur near the installation position of the ventilation waveguide window 1.
