4.Storage
4.1. Don’t open the moisture proof bag before ready to use the LEDs.
4.2. The LEDs should be kept at 30℃ or less and 60%RH or less before opening the package. The max. storage period before opening the package is 1 year.
4.3. After opening the package, the LEDs should be kept at 30-35%RH or less, and it should be used within 3 days. If the LEDs should be kept at 30-35%RH or more, and it should be used within 4 hours.
4.4. If the LEDs be kept over the conditions of 20%, baking is required before mounting. Baking condition as below: 70±5℃ for 12 hrs for bulk goods, 105±5℃ for 1 hrs for roll goods.
4.5. The environment have no acid, alkali, corrosive gas, intensively shake and high magnetic field.
5.Static
5.1.Static and Peak surge voltage can destroy LED, Avoiding Instantaneous voltage when turn on or turn off the lights.
5.2. Please wear Anti-static wrist band, Anti-static glove, Anti-static shoes in the course of operation, and the equipment must be grounded.
6.Test
6.1. Customer must apply the current limiting resistor in the circuit so as to drive the LEDs within the rated current. Otherwise slight voltage shift maybe will cause big current change and burn out will happen.
6.2. Also, caution should be taken not to overload the LEDs with instantaneous high voltage at the turning ON and OFF of the circuit. Otherwise, The LEDs will be destroyed, testing methods as follows:
6.3. The reverse voltage mustn’t exceed 5v when lighting on or testing the LED, otherwise,The LEDs will be damaged.
7.Else
Radiant color of LEDs have a little change with the current, recommended that LED is used in series and resistance, when lighting, please don’t see directly radiant surface of LED, otherwise LED will burn eyes.
