LED outdoor waterproof lamps and lanterns of three basic common sense!

Outdoor LED lighting lamps and lanterns need to stand the test of the ice and snow sun, wind and rain lightning for a long time, and cost is higher, and because of the outer wall use is more difficult to overhaul, shall meet the requirements of long-term, stable work. The semiconductor devices and the LED is too, if be affected with damp be affected with damp, can appear chip moisture absorption phenomenon, damage to the LED, PCB and other components, therefore, outdoor LED lighting lamps and lanterns is suitable to work in a dry and low temperature environment. But, in fact, the outdoor climate is not controlled, to ensure the long-term stability in LED outdoor harsh conditions, waterproof structure design of lamps and lanterns is very critical. Currently, the main waterproof technology of lamps and lanterns is divided into two directions: structure waterproof materials and waterproof. The so-called waterproof structure, after is the structure components in the product combination, have waterproof function. Such as the sound of floating photoelectric TSA1200 stadium lights/high lamp suite, light passes through the strict electrophoresis, powder baking process, to enhance the surface strength of the light body, water proofing property and corrosion resistance, protection grade reaches IP66, able to cope with the harsh outdoor environment, such as rainstorm, typhoon. Sound floating photoelectric TSA1200 stadium lights/high lamp suite and waterproof material, is a product design, set aside potting glue sealing the location of the electrical components, assembly when the glue material in waterproof. Two kinds of waterproof design is suitable for different product line respectively, each have advantages. However, lamps and lanterns, although have waterproof technology, when run it at outdoor, hard to avoid all kinds of damage from the outside world on waterproof performance, Mainly for the potting glue sealing materials waterproof lamps and lanterns) To look at the three main factors which influence the properties of waterproof lamps and lanterns: 1, uv ultraviolet exposure to the outside of the lamps and lanterns wire insulation layer, protective coating, plastic shell, potting glue, o-ring seal gaskets, adhesives have damage. Wire insulation aging crack, water vapor through the wire core crack penetrating into the lamps and lanterns. Lamps shell coating after aging, the shell edge coating cracking or splitting, there will be a gap. And electronic potting colloid, o-ring seal gaskets, parts after the glue between the aging, the same will, in turn, reduce the adhesive force, deformation, cracking and crack. These are uv damage to the waterproof ability of lamps and lanterns. 2, high and low temperature outdoor temperature changes a lot every day, summer day could be up to 5060 ℃, the surface temperature of lamps and lanterns evening fell to 1020 ℃, temperature can drop to minus winter snow day, annual temperature difference is bigger. The high temperatures in summer outdoor lamps and lanterns, materials will accelerate aging deformation. And when the temperature dropped to below zero, the plastic parts become fragile, may crack under the pressure of the cold air. 3, heat bilges cold shrink outdoor lamps and lanterns of the shell
