(5) In designing a circuit, the current through each LED can not exceed the absolute maximum rating specified

for each LED. In the meanwhile,resistors for protection should be applied, otherwise slight voltage shift will

cause big current change,burn out may happen. The driving circuit must be designed to allow forward voltage

only when it is ON or OFF.If the reverse voltage is applied to LED, migration can be generated resulting in LED

damage.

(6) Thermal Design is paramount importance because heat generation may result in the Characteristics

decline,such as brightness decreased,Color change and so on.Please consider the heat generation of the

LEDs when making the system design.LED

(7) Compared to standard encapsulants, silicone is generally softer, and the surface is more likely to attract

dust, requiring special care during processing. In cases where a minimal level of dirt and dust particles cannot

be guaranteed, a suitable cleaning solution must be applied to the surface after the soldering of components.

Refond suggests using isopropyl alcohol for cleaning. In case other solvents are used, it must be assured that

these solvents do not dissolve the package or resin. Ultrasonic cleaning is not recommended. Ultrasonic

cleaning may cause damage to the LED.
