First of all, let's take a look at the overall structure of the led flood light. The overall structure of the led flood light is the internal power supply, and the outside is a layer of glass. Between the lamp body and the glass, there will be a rubber sealing ring with a cavity inside. There is air outside. Generally speaking, the inlet and the sealing rubber ring are easier for water to enter, but when it reaches a certain level of dust and water resistance, it means that it has good waterproof ability, so under normal circumstances, water cannot enter. of. Even when used outdoors, it has corresponding waterproof performance.

So why does the led flood light appear water fog? Outdoor led flood lights are generally high-power lamps. When led floodlights start to work, they will start to heat up, and the air in the lights will expand. At this time, pressure will build up on the rubber ring, and the air will be used up; then, after the light goes out, the air pressure inside will decrease, and the air outside will be pressed in again. In addition to air coming in, water vapor will also come in, and then work, the water in the lamp may be more and more. The above is the description of the structure and water mist of the led flood light.
