CONDENSATION-PROOF AIR PRESSURE EQUILIBRIUM VALVE AND ILLUMINATING DEVICE INCLUDING SAME

摘要

The present invention relates to an condensation-proof air pressure equilibrium valve for and an illuminating device with the condensation-proof air pressure equilibrium valve installed on. The present invention is installed on an illuminating device which can be inflated or deflated by the air from the heat emitted from the inside by discharging the inflated air to outside when the illuminating device is lit to maintain the equilibrium of the air pressure, and drawing in outside air filtered to remove the moisture and dirt to protect the inside of the illuminating device from the moisture and dirt when the illuminating device is off and the inside air is deflated to maintain the equilibrium of the air pressure. Accordingly, the present invention can prevent the illuminating device from dirt accumulation and the condensation while enabling the illuminating device to be reliably used for an extended period of time and reducing the costs for component replacement and maintenance.;COPYRIGHT KIPO 2014
