When the LED display beads are damp, they will often cause problems such as blind lights and string lighting. After the problem breaks out, it is irreversible and even difficult to control. At this time, we need to take precautions in advance, and moisture-proof measures will start now!
1. Waterproof
Waterproof is to prevent liquid water, and moisture-proof is to prevent moisture and moisture.
The packaging materials of led display devices are mainly plastic materials such as epoxy resin. Plastic is a polymer material. The gap between the molecules of the polymer material is relatively large. The vapor water molecules can penetrate into the shell through the gap, but the liquid molecules are due to themselves The tension and fluidity are not strong, and the penetration rate will be much smaller.
Led display devices and outdoor lamp bead devices meet the waterproof function of the product through structural design, but both outdoor and indoor lamp beads are moisture-sensitive electronic components due to the characteristics of plastic materials.
Second, the harm of damp LED display
The LED display device is damp, and water vapor penetrates into the lamp beads. When the water vapor contained in the air penetrates into the lamp beads, when the electricity is turned on, the halogen in the water vapor will electrochemically react with the metal in the lamp beads. Short-circuit leakage or drop of electrodes, causing blind lights and string lighting abnormalities on the display lamp beads.
Case A: The decoration of a seaside building, the environment is humid, the led display screen has not been used for a long time, and moisture-proof measures have not been taken. After lighting, the lamp will die and string bright.
Case B: During the Spring Festival holiday, the weather was humid, and the led display screen was not used for a long time after power failure, and a batch of string lights appeared after the festival.
Third, the moisture-proof measures for the led display screen The first stop for moisture-proof-led display lamp beads storage
When the led display lamp beads are transported and stored, they can be heightened with objects to be waterproof and moisture-proof.
Moisture-proof second stop-led display lamp beads online
The lamp beads must be baked and dehumidified before mounting. We have corresponding solutions for different products and different levels of moisture.
Pay attention to the control environment when mounting, the recommended temperature is 20℃~30℃, and the humidity is 40%RH~60%RH. Pay attention to the patch cycle, use as soon as possible after taking out the oven or drying cabinet.
Moisture-proof third stop: LED display module packaging
Modules and boxes need to be vacuum packed or sealed with desiccant when stored or transported. Avoid installing the screen and the project being renovated at the same time, the environment is uncontrollable, and it is exposed to a humid environment for a long time without use.
Moisture-proof fourth stop: use of led display screen
After the screen is installed, it needs to be frequently lit and used. If the screen has not been used for a long time (usually 5-10 days), it should be dehumidified before use, and gradually increase the brightness and slowly increase the temperature to remove the accumulated in the screen. Moisture.
