Everlight Electronics Offers ‘Smart Binning’ for Shuen and Shwo
Everlight Electronics Co., Ltd. is now offering its customers a 3-step MacAdam Ellipse binning of all warm white color temperatures -- 2700K, 3000K, 3500K, and 4000K CCT -- for the Shuen (C06) and Shwo (C19) high power lighting LED series. Everlight’s ‘Smart Binning’ initiative is aimed at reducing the variation in chromaticity in lighting applications.
In lighting applications, color consistency is a key determinant of a product’s quality and appeal. 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. Before, 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.

Everlight’s ‘Smart Binning’ allows for an easier, alternative solution to maintaining color consistency in lighting applications. No bins need to be selected and clustered based on complex calculations. Everlight simply offers part numbers for each warm white CCT that represents a 3 step MacAdam ellipse, This is the easiest and most effective way to manufacture color consistent lighting applications.
