During the use of single or multiple LEDs, the recommended range of IF for DC drive current of each LED is 10mA-20mA. Instantaneous pulse will destroy the internal fixed connection of LED, so the circuit must be carefully designed, so that LED will not be impacted by over-voltage (over-current) when the circuit is opened and closed.

The consistency of luminous brightness and color is required when multiple LEDs are used. Therefore, the driving mode and driving conditions should be fully understood. Under normal conditions, the consistency of color and brightness of 20 mA light splitting should be guaranteed. To obtain uniform brightness and color, LEDs of the same batch shall use the same current, and shall not be mixed with multiple packages to avoid brightness difference. Refer to the product specification for the relationship between IV, IF, VF, WL and temperature of LED. If you want to know more LED chip models, specifications and parameters, please consult the customer service personnel of Lanjin Optoelectronics.

Storage:

In order to prevent moisture, LED should be stored in a dry and ventilated environment, with storage temperature of - 40 ℃ -+100 ℃ and relative humidity below 85%. In order to avoid rust on the bracket, LED should be used up within 3 months under its original packaging. If the LED packaging bag is opened, it must be used as soon as possible. At this time, the storage temperature is 5 ℃ - 30 ℃, and the relative humidity should be below 60%.
