Now there are more and more types of outdoor lamps, and there are corresponding lamps to install and use in any scene.
Such as outdoor landscape lights, street lights, marine lights, emergency lights, outdoor entertainment lights and other outdoor lighting fixtures, these fixtures are used outdoors, and will face the complex and changeable outdoor natural environment, such as rain and snow weather, High temperature and low temperature weather will cause the air pressure in the lamp to fluctuate and change, which will make the seal fail, resulting in water ingress and failure.
Therefore, outdoor lighting must consider the problem of internal and external air pressure balance and waterproofing. Most of this problem is achieved by outdoor lighting waterproof and breathable components (lighting waterproof breathable membrane or lighting waterproof breathable valve).
The waterproof and breathable components of lamps have good waterproof and dustproof performance, which can prevent water, oil liquid and particles from entering the lamp housing and protect the light-emitting elements.
The waterproof and ventilating components of the lamps can ensure good breathing and ventilation requirements, can quickly balance the internal and external stress of the lamp housing, and avoid the lamps being subjected to fluctuating pressure.
Water separation and moisture permeability, keep the cavity dry, avoid condensation and dew, and affect the light efficiency; the porous structure of the raw materials of the waterproof and breathable components of the lamps has a high porosity, which effectively reduces the generation of salt crystals.
The waterproof and ventilating components of the lamps can also block dust, block particle pollution, and prevent dust accumulation on internal parts; the waterproof and ventilating components of the lamps are resistant to high and low temperature changes, avoid internal and external pressure imbalance, and protect the continuous operation of internal components; The waterproof and ventilating components of the lamps have good corrosion resistance and can maintain the factory protection level of the equipment for a long time.
