Description

[0002] A tempered glass needs to be installed outside the display screen of a waterproof stage light, through which the content of the display screen can be clearly seen. The waterproof stage light needs to install a breather valve to maintain the balance of internal and external air pressure. The breather valve can play a waterproof role, but cannot cut off water vapor. When there is a temperature difference between the internal gas of the waterproof stage light and the tempered glass, the high-temperature water vapor will liquefy into water mist when meeting the tempered glass with lower temperature, causing the display screen to be blurred and the screen content to be unclear. Even if the waterproof stage light is heated as a whole to evaporate the water mist, the water mist will also dissipate very slowly, resulting in problems such as affected use and complaints.
