it will be possible to use separate LED colors with high accuracy

This will enable us to stably produce and offer a white LED that has the least variation in chromaticity while keeping the production cost low by discontinuing the “sorting” process before shipment. We believe that at the destination sites it will be possible to use separate LED colors with high accuracy and that will help to produce quality lighting equipment. Citizen Electronics Co., Ltd will start color control using “3-Step MacAdam ellipses” at the mass production level, taking the initiative in the lighting industry.

Nowadays the use of white LEDs in general lighting is rapidly progressing. There is always a possibility that a great deal of interest will be focused on the LED’s energy-saving performance based on its high luminous efficacy. However, we consider that it is very important to offer quality products stably with no variation in color as well as improving the luminous efficacy.YAHAM Optoelectrionics Co., Ltd will continue to utilize the “CITIZEN” tradition of “Precision Engineering Technology”, and advance the development of high-quality LED products as light sources for general lighting.

Cree customers now have access to our industry-proven TrueWhite technology, allowing them to quickly deliver better products to the market, faster,” said Chuck Swoboda, Cree chairman and chief executive officer. “Cree TrueWhite technology is already installed in thousands of locations including restaurants, retail stores, and others that demand both high-quality light and energy-efficiency.”
