(Summary description)As the illumination range of outdoor lighting fixtures expands, the size of the fixtures also increases. However, this creates a problem: when the fixture is in use, it generates heat and expands, then contracts as it cools, creating pressure differences between the interior and exterior of the fixture. If completely sealed, the fixture may be damaged. So what can be done? This is where a special device called a "breather" comes in! This magical device also called respirator has the following functions: firstly, it allows the fixture to breathe, allowing gas to freely enter and exit, thereby avoiding pressure differences; secondly, it can be waterproof and dustproof, protecting the interior of the fixture; finally, it can promote heat dissipation and extend the life of the fixture. Therefore, the breather(respirator) is an important design element of lighting fixtures that is worth learning about. That’s why Customers often ask what the respirator on LONGSUN’s lamps is for and how it works. Many people only know that it has a waterproof function but don't know its specific working principle. Today, let's talk about it.   The breather uses a waterproof and breathable film material (such as microporous e-PTFE), which is encapsulated in a housing made of plastic or metal, and then installed on the lighting fixture. This type of film material has a microporous structure that allows gas to freely enter and exit, but liquid water cannot pass through, thus achieving the function of waterproof and breathable. When water vapor condenses into water droplets, the micropores of the waterproof and breathable film are blocked by the water particles, so the water molecules cannot escape smoothly from the water droplets, thereby achieving the waterproof effect.   There are many benefits to using a breather. It can prevent internal condensation and fogging of the fixture, improve its service life, balance internal and external pressure differences, prevent damage to the fixture, and promote heat dissipation to avoid overheating and damage to the fixture. In addition, the breather has other advantages, such as dust and oil resistance, a high protection rating of up to IP68, and resistance to chemicals, high and low temperatures, and aging, making it suitable for use in harsh environments.   In conclusion, the breather is a crucial component in the design of lighting fixtures, and its functions extend beyond just waterproofing and breathability. The dual properties of waterproofing and breathability provided by the waterproof permeable valve not only help prevent mist and condensation but also improve the quality and lifespan of LED fixtures, such as area lights and floodlights. By using a breather or respirator, we can increase the reliability and longevity of lighting fixtures, ensuring safer and more durable outdoor lighting solutions.
