As everyone knows, the water is LED lighting predators, once the lamp is equal to the water, declared the end of the LED lamp life, LED's longevity advantages but also to maintain the vanish like soap bubbles, causing considerable inconvenience, bring economic loss to the customer, even many times not through engineering acceptance.
Plug at the entrance of the inlet line inlet water inlet pipe into the water, has long been the shadow of the outdoor LED lighting industry lingering. However, the structure of the LED guardrail tube, plug and outlet to avoid the emergence of water from the basic situation, the general use of waterproof guardrail tube, more uniform color, greatly reducing the maintenance of the latter.
Pressure balance is the key of waterproof, even LED guardrail lamp sealing good, cast into the water is no problem, but not installed in the outdoor wind and rain is no problem, work in the air will produce negative pressure, inhale the water vapor, will produce water vapor. The seal is very difficult to cure the problem, because the fence tube is used outdoor hot weather, outdoor sunlight temperature may have 40-50, but when the cold weather in different regions, and low to several degrees below zero or even ten degrees, temperature difference is so big, sealing better. The greater the pressure on the sealing area.
So the key is not sealed, but the fence lights with the outside of the air pressure to be balanced, the solution is ventilation, exhaust is once and for all.
