Question: What data do I need from LED vendors for implementing binning compensation?
Answer: To implement binning compensation, one needs access to the LED datasheet that includes binning details of forward voltage, dominant wavelength, and photometric luminous flux. Hardware design is constrained by the forward voltage. Dominant wavelength and photometric luminous flux have to be considered for firmware design. To learn more about binning and how it affects your design, please refer to the article White Light and Color Mixing: A Single Approach and AN47518 Firmware—Building Binning Tables for Color Mixing Using EZ-Color HB-LED Controllers available at www.cypress.com.
