So I am planning on setting up a scanning system to run a RGB Led Matrix to prevent the pins from being blown out. I was wondering if anyone could tell me if each seperate color from the RGB Led used 20 ma or if it just used 20 ma as a whole? Here are the specifications below.
Description
Specifications:
Forward Voltage: R: 1.8-2.2 G: 3.0-3.4 B: 3.0-3.4
IV: R: 5000-6000 G: 6000-7000 B: 2500-3000
XY/WLD: R: 620-625 G: 515-520 B: 460-465
Light Color: RGB
Size: 5mm length :about 4.5CM
Emitted Colour : Red / Green / Blue
Pins sequence: RED/Common Anode(positive terminal)/Green/Blue
Lens Color : water Clear/diffused
Luminous Intensity: 4000/8000/5000mcd
Forward Voltage (V) : 2.1~3.4
View Angle: About 25 degree
Forward Dominant LuMen(LM) Reverse Power
Voltage(V) wavelength(mm)K current(uA) Angle (deg)
If=20mA If=20mA If=20mA Vr=5V
Min Typ Min Typ Min Typ Max
Red 2.1 2.4 620 630 3000 4000 10 20-25
Green 3 3.4 520 530 6000 8000 10 20-25
Blue 3 3.4 460 465 4000 5000 10 20-25
Each color uses 20mA, so 60mA with all channels on full.
I'm not sure how it was originally formatted - it's clearly been mangled badly... but the giveaway is that they have the current listed three times (presumably once per channel).
DrAzzy:
Yeah, that's typical. They don't waste money on things like detailed datasheets.
Not always. It's just that they don't waste money on small quantity buyers, especially for overseas where they have to translate. Sometimes the specs are actually online, but are hard to find because they are in Chinese language. Google sometimes is weak at finding things in different languages, different countries. I know this because I've actually managed to track down some LED modules with a lot of persistence. You can't expect to just type the part number into Google and have it appear in the first three hits, like more common stuff that is marketed in North Americal and EU.
