The products include 3 series: decorative light source, outdoor led light source and automotive led light source. Most of our customers are factories from Europe and America, while a few are traders and suppliers.

Team activity

1. Material confirmation
Is the LED BIN rating of the feed matched? For example: voltage CIE BIN brightness and other parameters are the same level, the same level should be used together. Whether the positive and negative polarities meet the requirements, whether the different foot positions meet the requirements. If the same level of LED is not applied to the same item, its applicability should be evaluated first. (If the different voltage BINs are used together, the brightness may be different, and different CIE BINs may use the luminescent colors together to make a difference).

2. Preventive measures after opening the package
After unpacking, take the whole roll dehumidification measures as much as possible, and dehumidify the conditions: baking at 70 degrees for 4-12 hours. The dehumidified material should be used as soon as possible (within 24 hours). Remaining material should be sealed or placed in an environment with 10-40 degrees humidity and no more than 30% humidity.

3. Electrostatic Protection
Electrostatic protection LED is an electrostatic sensitive electronic device. Various measures should be taken to avoid static electricity. For example: Wear an electrostatic ring during use. All devices, equipment and instruments should be grounded. It is recommended to test the assembled LED product to check whether the LED is damaged by static electricity.

4. Cleaning
It is recommended that isopropyl alcohol be used to clean the LEDs. If using other solvents for cleaning, make sure that the solvent does not affect the epoxy, silicone, or stent silver layers. Ultrasonic cleaning is not recommended to avoid damage to the LED. If it is unavoidable, please perform a pre-test beforehand to confirm whether it has adverse effects on the LED or potential problems.
