Caution: LED is a current-operated device. The slight shift of voltage will cause a big change of current, which may damage LEDs. Customers should use resistors in series for Over-Current-Proof. In order to ensure consistent light-color on multiple LEDs connected in parallel, an individual resistor separately is suggested, as Circuit A below shown. If the light-color of each LED shown as Circuit B might be different due to the different I-V characteristics of each LED. Too high ambient temperature will affect the brightness of LED and its properties, so it's important to keep the LED away from heat to maintain its performance.
Storage: The recommended storage before unpacking: Temperature: 5℃30℃; Humidity: below 60% RH. Dehumidification should be done before use when stored for more than 2 months. Conditions 60℃/12 hours. The suggested storage requirement should be temperature in 530°C, humidity below 30% after opening the package. LED is a component that is sensitive to humidity, which requires being stored in a sealed container with desiccant or nitrogen moisture-proof cabinet to avoid moisture absorption after unpacking. The moisture-proof level of LED is MSL3. The component should be used within 168hrs (7 days) after unpacking and be welded as soon as possible. If the component is exposed to air for more than 168hrs (7 days) or the desiccant has expired, dehumidification should be done.
Electrostatic Protection: LEDs are sensitive to electrostatic discharge (ESD), which can damage their structure and cause abnormal behavior such as excessive leakage current, low VF or no illumination. To avoid ESD, the following measures should be taken:
Anti-static wristband or anti-static gloves should be worn when handling LEDs.
Grounding protection should be done for all machinery and equipment tools, work tables, material racks, etc. (within 10Ω of grounding impedance).
Anti-static bag, anti-static box, and anti-static turnover box should be used for storage or transportation. Never use plastic.
It is recommended to use an ion fan to suppress electrostatic generation during operation. The voltage of the static field should be less than 100V in a 1-foot radius from the LED component.
Clean: It is recommended to clean LEDs with isopropanol or other alcohol solvent, rather than a corrosive solution.
