What are the functions of waterproof and breathable membrane for outdoor lighting?

Potential problems faced by outdoor lighting lamps:The enclosure of outdoor lamps will be affected by environmental temperature and pressure changes. Temperature changes, dust, dirt and moisture can have a considerable impact on the electronic components of outdoor lighting. For example, rain may cause the lamp shade to cool rapidly, resulting in very low air pressure or higher vacuum in the lamp shade. This will seriously affect the performance of the internal components of the bulb.

Solution: Through the waterproof and breathable membrane of outdoor lighting, the air is continuously exchanged to keep the pressure balance between the inside and outside of the enclosure. After the waterproof and breathable membrane is installed on the shell of outdoor lamp, the pressure difference caused by the change of external temperature will no longer have a negative impact on the shell, because the waterproof and breathable membrane of outdoor lighting can quickly balance the indoor and outdoor pressure. When the ambient temperature and pressure change, the enclosure.
