New package family seddLED – Smart Embedded Digital Driver LED

DOMINANT proudly presents its’ new seddLED3.0 family member: A3A-FKG-RGB-1, which is pre-calibrated to individual Red, True Green and Blue color at 400mcd, 1600mcd & 250mcd respectively. Interestingly, the True Green and Blue color is pre-calibrated to only a single wavelength (1nm)!

Most of the standard RGB LEDs are binned for both color and intensity of each chip in a package. Usually, it will have 3-6 binning categories depending on the LED maker. While, binning significantly reduces possible color distribution, it does not remove color mixed inconsistencies completely.

The advantage of A3A-FKG-RGB-1 is that it is able to fine tune the variation of color & intensity by controlling the LED Peak Current (PWM), Wavelength Calibration and Temperature Compensation.
