Photography lights always need to be charged. What happened?

Photographic lamps are always charged for the following reasons:

1, the high brightness of the flash needs to be triggered by DC high voltage inside the camera, and the transformer will increase the energy of the battery to more than 300 V.

2. Leakage of 2.LED lamp beads: the machinery and equipment are not grounded, and the personnel are not wearing electrostatic bracelets, resulting in improper electrostatic protection.
