AI Technical Summary
Existing floodlights are prone to bursting and damage during operation due to heat accumulation causing internal gas expansion and creating high temperature and pressure.
A gas duct connects the floodlight cover to the hollow explosion-proof ring. High-temperature gas is introduced into the hollow explosion-proof ring through the gas duct, and the internal pressure and temperature are reduced by the heat conduction plate and heat sink system. Combined with heat dissipation holes and dust cover, the airflow is discharged to prevent explosion.
It effectively reduces the internal pressure and temperature of the floodlight, preventing the equipment from bursting and extending its service life.
