Do LED Chip need to be dehumidified
LED Chip need to be dehumidified . The following are the key points of dehumidification of LED Chip:
- Packing and storage : The products should be packed in moisture-proof and anti-static aluminum foil bag and stored in an environment where the temperature is <30℃ and the humidity is <60%RH. The products should be used within 6 months. If not used up, need to dehumidify the oven.
- Handling after unpacking : After unpacking, unused LED Chip should be vacuumed and sealed or placed in a moisture-proof cabinet. Simple sealing such as transparent tape is prohibited. Before use, it is necessary to confirm whether the moisture-proof beads of the humidity card are discolored, and if they are discolored, they need to be roasted and dehumidified.
- Use of environmental control : in the wet season, the environment of the workshop should be controlled, keep the temperature <30℃, humidity <60%RH. For outdoor LED Chip, it is necessary to meet the waterproof function through the structural design.
- Routine maintenance : regularly clean the dust inside and outside the LED display to improve heat dissipation efficiency and reduce water vapor attachment. In a humid environment, check whether dew or frost occurs inside the display periodically.
Dehumidification is of great significance for protecting LED Chip and prolonging their service life.
What are the specific steps of dehumidification of LED Chip?
Storage Environment control :
- Storage temperature <30 ° C, humidity <60%RH.
- Use moisture-proof and static-proof aluminum foil bag to avoid squeezing and piercing.
- Store in moisture-proof cabinet and use within 6 months.
Handling after unpacking :
- The unused lamp beads after unpacking should be vacuumed and sealed or placed in a moisture-proof cabinet.
- Before use, check whether the moisture-proof LED Chip of the humidity card is discolored, if it is discolored, it needs to be baked and dehumidified.
display dehumidification :
- Before preheating and aging the display, use the dehumidification mode of the air conditioner or a dehumidifier to dehumidify the display.
- The display is in a closed environment, and the dehumidification time is not less than 2 hours.
- If there is water stain on the surface, continue to dehumidification and install a fan to dry, for not less than 5 days.
Routine operation and maintenance :
- It is often lit and used to evaporate water vapor through its own heat.
- Use the dehumidifier or air conditioner in the humid season.
Following the above steps can effectively extend the service life of the LED Chip and ensure the stable operation of the electronic equipment.
If the lamp bead humidity card changes color, what should I do?
1. confirm moisture :
- First of all, confirm whether the LED Chip are indeed damp, you can judge by observing the degree of discoloration of the moisture-proof beads on the humidity card.
2. Baking dehumidification :
- If the LED Chip has been damp, it is recommended to bake dehumidification.
- Baking conditions are usually 60℃/24 hours, the specific conditions may vary from manufacturer to manufacturer, it is recommended to refer to the recommendations provided by the manufacturer.
3.Avoid using damp LED Chip :
- Damp beads should not be lit again to avoid circuit problems or fire.
- If needed, ensure that the LED Chip has been fully dehumidified and returned to a dry state.
4.Contact the seller :
- If the outdoor lighting beads are damp, you should contact the seller in time to negotiate the related costs and follow-up treatment of baking.
