Cree has added new neutral and warm bins, which are the smallest bins in the industry, to its multi-chip MC-E EasyWhite and XLamp MP-L LEDs. The new bins avoid the need for buying several small bins and carry out complex mixing of colors.
The new technology provides a two-step single MacAdams ellipse bin for every color temperature. The small bins are optimized to get color consistency equal to incandescent.
The TeraStack Solution
The EasyWhite binning feature of the company’s multi-chip LED components allows customers to choose the lumen output and color temperature specifications, for enhanced LED-to-LED consistency in color, and simplified LED system design. Each bin is smaller by 94% than the ANSI C78.377 quadrangle, and smaller by 75% than the existing EasyWhite bins. These comparisons are made at the intersection point of the standard neutral/warm CCT points and black body locus.
The two-step EasyWhite bins, along with MC-E and XLamp MP-L LEDs, are offered in 4000K, 3500K, 3000K, and 2700K. Cree’s Director of Marketing, Paul Thieken stated that the LED binning has simplified the problem of integrating the efficiency of lighting class LED with the color consistency of incandescent lights. He added that these small bins have the ability to decrease costs for customers.
