Calibration of RGB LED's

[BrunoK]

Hi there,

can anyone explain why and how an RGB LED is calibrated?

I'm pretty new in this topic, so if more information is needed please let me know

Best Regards

Bruno

Can you tell me about LED of detail?
You question is so shprt

Well I actually don't have any specific LED information....

All I know is that it is RGB LEDS :|

I have found some information about measuring the LEDS waveæength, but I was more thinking in terms of "overall" picture, like why a LED has to be calbrated, and then maybe differnet approach how to do that.

But so far all I know is that it is an RGB LED.

a LED is basically a diode and follows the diode IV curve. the way to bias an LED is by current source. since luminance is directly proportional to the current of LED, in order to match the brightness of LEDs, u need to make sure that you have ways to bleed in or remove additional current going into each LED.

Hi all friend !
this project i finished 2 year ago.
You can using Red led,Green led and Blue led.
anod node all of them is common.
3 pins K u connect with 3 pins of MCU ( Pins support PWM).
with fix number for one u can make a diiferent color.
So u can make 255x255x255 colors if u use PWM 8 bits !!
Good luck
