ePTFE working principle: In the state of water vapor, water particles are very small, according to the principle of capillary movement, can smoothly penetrate into the capillary to the other side, resulting in steam penetration phenomenon. When the water vapor condenses into water beads, the particles become larger, due to the effect of the surface tension of the water beads (water molecules "pull against each other"), the water molecules can not be smoothly separated from the water beads to penetrate to the other side, that is, to prevent the penetration of water, so that the permeable film has the waterproof function.

Potential problems: Outdoor luminaire enclosures are subject to changes in ambient temperature and pressure.

Temperature changes, dust, dirt and moisture can have a considerable impact on the electronic components of outdoor lighting fixtures. For example, rainfall can cause a rapid cooling of the lamp casing, which can create a vacuum of 200mbar(3psi) or more inside the casing. This will seriously affect the performance of the internal components of the lamp.

Solution: Maintain the balance of pressure inside and outside the shell by constant ventilation. After the waterproof breathable film is installed on the outdoor lamp cover, the pressure difference caused by the change of external temperature will no longer have a negative impact on the cover, because the waterproof breathable film can quickly balance the pressure inside and outside the shell when the ambient temperature and pressure change.
