extremely narrow binning from an LED manufacturer

Color consistency is a key determinant of a product’s quality and appeal in lighting applications. This consistency is not only determined by the control of chromaticity from LED to LED inside a product but from one completed product to the next.

There are two solutions were possible to obtain color consistency. One way was to mix different color bins of an LED onto a single board to achieve a certain CCT. However, this solution requires complex mathematical algorithms to ensure a balanced CCT and relies heavily on secondary optics to diffuse and assist in mixing colors. This is a valid solution but very time consuming on the manufacturing level.

Another solution is to negotiate extremely narrow binning from an LED manufacturer. This is not cost effective and may affect availability and lead times, due to yield distribution on the LED manufacturing level.
