Outdoor LED Fixtures Protective Coating

Outdoor lighting need to withstand long-term snow and ice, wind and rain lightning test, and the higher cost, and because the use of more difficult to repair on the external walls, Outdoor LED Fixtures to meet the requirements of long-term stable work. The LED is a delicate semiconductor components, if damp, there will be chip moisture absorption, damage to the LED, PcB and other components, therefore, LED suitable for work in dry and low temperature. To ensure that the LED in the harsh outdoor conditions, long-term stable work, lighting waterproof structure design is critical.

At present, the lamp waterproofing technology is mainly divided into two directions: structural waterproof and waterproof material. The so-called structural waterproof, Outdoor LED Fixtures that is, in the product after the combination of structural components, already have a waterproof function. The material waterproof, it is the product design, leaving the potted plastic sealed electrical components of the location, assembly with glue material to achieve water. Two waterproof design are suitable for different product lines, each have their own advantages

UV radiation on the outside of the lamp insulation layer, Outdoor LED Fixtures protective coating shell, plastic parts, potting, sealing rubber tape, adhesive has a damaging effect.

After the wire insulation layer is cracked, the water vapor penetrates into the interior of the lamp through the gap of the wire core. After the lamp shell coating aging, Outdoor LED Fixtures the shell edge coating cracked or stripped, there will be gaps. After the plastic shell is aged, it will crack. Electronic potting colloid aging will produce cracking. Seal rubber tape aging deformation, there will be gaps. Structural adhesive between the adhesive aging, reduce the adhesion will appear after the gap. These are UV damage to the lamp waterproof capacity.

Outdoor daily temperature changes in the summer daytime lighting surface temperature can rise to 50 ~ 60 ℃, late to 10 ~ 20 qC, winter ice and snow days can be reduced to zero, the annual temperature difference is greater. Outdoor lighting in the summer high temperature environment, the material accelerated aging deformation. Outdoor LED Fixtures When the temperature drops to zero, the plastic parts become brittle, under the oppression of ice or cracking.

Lamp shell thermal expansion and contraction: changes in temperature lead to thermal expansion and contraction of lamps, different materials (such as glass and aluminum) coefficient of linear expansion of the two materials in the junction will appear displacement. Thermal expansion and contraction process repeated, Outdoor LED Fixtures the relative displacement is also repeated, great damage to the airtight lighting.

Based on the structure of waterproof design of the lamp, need to closely fit the silicone seal waterproof, shell structure is relatively sophisticated and complex, usually suitable for larger lamps, such as strip floodlights, Outdoor LED Fixtures square and circular cast light, etc., high power Lamps.

Structure of waterproof lamps only pure mechanical structure assembly, Outdoor LED Fixtures the use of simple tools, assembly processes and processes less, assembly cycle is short, the production line repair convenient. Lamps through electrical performance and waterproof test, Outdoor LED Fixtures you can package shipping, for short supply cycle of the project.
