Abstract

Solid state lighting devices (e.g., lamps and fixtures) are produced using unbinned/uncharacterized LEDs from an entire LED production “cloud” by way of sequentially measuring light emitted from the unbinned LEDs, and then assigning/placing each unbinned LED immediately into an associated LED product group (e.g., directly onto a PCB that forms part of the final lamp/fixture). The group assignment for each LED is based on how its measured light matches with other LEDs based on flexible group characteristics, which are generated in accordance with user-defined parameters, whereby each LED is placed in a product group such that light collectively generated by the LEDs of each product group complies with the user-defined parameters. The flexible group characteristics are also adjusted in real time (i.e., as batch-related characteristics of the LED “cloud” are acquired by way of the sequential testing), whereby the LED assignment process is modified for each LED batch.
