With the world's highest efficiency: EPISTAR 216lm/W warm white high voltage chip combination

EPISTAR R & D Center (EPISTAR LAB): the highest efficiency warm white chip combination in Japan before.

With excellent luminous efficiency, high color and competitive performance of the red and blue chip portfolio has a place in the warm white light application market. Recently EPISTAR LAB successfully developed the latest combination of red and blue chips, in the 5mA operation, the color temperature of 2700K, the color is 87, and its luminous efficiency up to 216lm/W. When the 15mA operation, the luminous efficiency is also 197lm/W.

The implementation of EPISTAR LAB new world record by a variety of the most advanced technology in the high voltage chip combination, such as a transparent substrate conversion process, reducing design, quantum well light absorption fine structure, increase the extraction rate of photon distribution uniformity and improve current with high quantum efficiency collocation low impedance quantum well structure etc.. This combination of red and blue chips in the warm white color gamut, showing excellent luminous efficiency performance, and suitable for replacement bulbs, commercial lighting, lamps and other applications. EPISTAR (EPISTAR) will continue to develop more advanced chip technology, and work closely with customers to provide better solutions to the lighting market.
