Esidon Opto Combines ANSI BIN Group with MacAdam Ellipse Enhancing the Color Consistency of Luminaires

In order to provide comprehensive sales service and enhance the capacity utilization of PLCC, the Taiwanese LED manufacturer, Edison Opto, initiates to combine ANSI BIN group with the concept of MacAdam ellipse and subdivide the color temperature into 9 subgroups. The new BIN group is conducive to inventory management. Also, the packaging sales service which is provided by Edison Opto is more convenient to customers’ product selection.

Take 2700K for example, Edison’s new BIN group is to subdivide the color temperature into 9 subgroups (the outside of 5-step MacAdam ellipse are 27A, 27B, 27C and 27D; the section between 3-step and 5-step MacAdam ellipse are 27S, 27T, 27U and 27V; the inside of 3-step MacAdam ellipse is 273). Customers can mix components from different BIN groups to attain the desired color temperature (for example, we can mix 27U and 27S in 1:1 ratio to control the color temperature within 3-step MacAdam ellipse) so that the products which are off-center can achieve the goals of color consistency and CCT control.

The new PLCC BIN group can not only control color temperature more precisely but also enhance the capacity utilization. Moreover, Edison Opto can provide customers the mix BIN service at a preferential price and help to improve the color consistency of luminaires.
