(4) Leds may be damaged in ultrasonic cleaning. For safe, sample test first before
mass cleaning.
3. Careful
Using series connection protecting resistance to keep leds working stably, resistance
value counting: R=(VCC-VF)/IF, VCC=Power Supply Voltage; VF=Leds Drive Voltage;
IF=Current.
4. Electrical Characteristics Testing and Led Using
ꢀ Testing VF, Brightness and Wavelength at 20mA; Testing IR, IR should be less
than or equivalent to prescribed value when set VR=5V.
ꢀ Testing or using leds, drive each led at the same current to keep consistence of
brightness or other characteristics.
ꢀ Operating temperature: -40ć~85ć
ꢀ Do not using different BINs(Marked on every bag) on one product to avoid color
and brightness difference. If mix-up is inevitable, apply leds according to different
circuit., put nearest BINs together.(Avoid this situation if possible.)
5. Storage Conditions
ꢀ Circumstance Temperature: -40ć~100ćꢂꢀ-20ć~50ćꢀis recommended.
ꢀ Circumstance Humidity: 30%~70%, 40%~60 % is recommended.
