Caution:


  • LED is a current-operated device. The slight shift of voltage will cause big change of current,  which will damage LEDs. Customer should use resistors in series for the Over-Current-Proof.

  • In order to ensure consistent light-color on multiple LEDs connected in parallel, individual  resistor separately is suggested, as Circuit A below shown. If the light-color of each LED  shown as Circuit B might be difference due to the different I-V characteristics of each LED.

  • Too high ambient temperature will affect the brightness of LED and its properties, please be  away from the heat so as to keep performance better.



Storage:


  • The recommended storage before unpacking: Temperature :5℃~30℃; Humidity :below 60%  RH. Dehumidification should be done before use when it stored for more than 2 months.  Conditions 60℃/12 hours.

  • The suggested storage requirement should be temperature in 5~30°C,humidity below 30%  after open the package.

  • LED is a component that is sensitive to humidity,which requires to be stored in sealed  container with desiccant or nitrogen moisture-proof cabinet to avoid moisture absorption after  unpacking.

  • The moisture-proof level of LED is MSL3. Component should be used in 168hrs(7 days) after  unpacking and be welded as soon as possible.

  • Component should be dehumidified when it is exposed to the air for more than168hrs(7days)  or desiccant expired.


Electrostatic Protection:


  • Due to LED(especially the blue, yellow green, purple, white, pink LED in InGaN structure) is  sensitive to electrostatic that would damage to its structure,which may perform abnormal  after being attacked by electrostatic or overload current,such as excessive leakage current,  low VF or unable illumination, please mind as below.

  1. Anti-static wristband or anti-static gloves should be worn to touch LED.

  2. rounding protection should be done for all machinery and equipment tools, work tables,  material racks, etc..(within 10Ω of grounding impedance).

  3. Anti-static bag, anti-static box and anti-static turnover box should be used for storage or  transportation. Never used plastic.

  4. It is recommended to use ion fan to suppress electrostatic generation during operation.

  5. The Voltage of static field is less than 100V in 1 foot radius from LED component.

Clean:


  • Recommend using opropanol and other alcohol solvent rather than corrosive solution to clean  LED.
