Abstract
A manufacturing process for storing measured light output internal to an individual LED assembly, and an LED assembly realized by the process. The process utilizes a manufacturing test system to hold an LED light assembly a controlled distance and angle from the spectral output measurement tool. Spectral coordinates, forward voltage, and environmental measurements for the as manufactured assembly are measured for each base color LED. The measurements are recorded to a storage device internal to the LED assembly. Those stored measurements can then be utilized in usage of the LED assembly to provide accurate and precise control of the light output by the LED assembly.

A process for manufacturing a light emitting diode (LED) assembly including LEDs of a plurality of colors, comprising:
- (a) driving all LEDs of a first color and measuring information of an optical output of the driven LEDs;
- (b) measuring a first environmental condition;
- (c) storing in a memory in the LED assembly the measured first environmental condition and the measured information of optical output;
- and
- (d) repeating the driving (a) and measuring (b) and storing (c) for the LEDs of each of the plurality of colors.
A light emitting diode (LED) assembly comprising:
- (a) a plurality of sets of LEDs of a plurality of colors, each set of LEDs including LEDs of only one specific color of the plurality of colors;
- (b) control electronics configured to control driving of the plurality of LEDs, the control electronics including a memory storing measured information of optical outputs for each set of LEDs at at least one measured environmental condition.
