Can the LED projector be water-proof and foggy

2021-08-05

When we use electronic products, it's necessary to dip some water and soil. The same is true for outdoor lighting. But the general led floodlight itself has good waterproof function, but is there any prevention function for the water mist caused by the temperature change? Today we will discuss whether the LED floodlight can be waterproof fog.
 
 
The power supply of the floodlight is inside the lamp box, and the outside is a layer of glass. Between the lamp body and the glass, there is a rubber sealing ring, and the inside is a cavity and the outside is air. Generally speaking, water is easy to enter the wire and the sealing rubber ring, but it reaches the dust-proof and waterproof level of IP66, indicating that it has good waterproof ability and can not enter under normal conditions.
 
 
 
Once the lamp starts to work, it will heat up, and then the air will expand. At this time, it will form pressure on the rubber ring. When the air runs out, it will press through or press out a gap at some relatively weak position of the rubber ring. In addition to the air, the water vapor will come in, and then it will work again and again. The water in the lamp may be more and more stored. Therefore, the LED projection lamp can not prevent the generation of water mist.
 
 
 
But there is a respirator on the back of the floodlight. After the light is turned off, the outside gas will be replenished here, and the water will be isolated when the gas is replenished. In this process, the internal and external pressure is balanced, and no pressure is caused to the rubber ring. It can achieve good waterproof fog effect.
