Description
Technical Field
[0001] The utility model belongs to the technical field of spotlights, in particular to a spotlight used in an EMC shielding room. Background Art
[0002] The electromagnetic shielding room is an important part of the electromagnetic compatibility (EMC) field. The electromagnetic shielding room is a steel house. Cold-rolled steel plate is its main shielding material, including six-sided shells, doors, windows and other general house elements. It only requires strict electromagnetic sealing performance and corresponding shielding treatment for all inlet and outlet pipelines to block the entry and exit of electromagnetic radiation. It is usually necessary to install multiple spotlights in the EMC shielding room for internal lighting.
[0003] The spotlights installed in existing EMC shielding rooms are usually fixed and do not have good adjustment functions. When the spotlight needs to be placed close to the lighting electronic equipment, it cannot be illuminated well, and the staff needs to use other lighting equipment for adjustment. This not only adds cumbersome steps, but the added lighting equipment is likely to affect the test of electronic equipment. Therefore, we propose a spotlight for use in EMC shielding rooms.
