Manufacturing of LEDs and binning

03-02-2022

LEDs are mass-produced. LEDs from the same manufacturing run usually vary a bit in lumens, color and forward voltage. To ensure that they still meet the quality specifications, a 'binning process' is applied at the end of production. The properties of the produced LEDs are measured at lightning speed and then sorted into subclasses with defined properties. These subclasses are denoted by the English word 'bins'. LEDs of unequal quality are actually sorted into different bins, so that after sorting each bin only contains products of sufficiently equal and defined quality.
