Cree Expands Green LED Product Family
Durham, NC, May 4, 2004 - Cree, Inc. (Nasdaq: CREE) today introduced two new versions of its light emitting diode (LED) product family. The new green versions include the XT-290(TM) LED and the XB-900(TM) LED. The XT-290, offered in a 527nm version, has a typical radiant flux of 9mW at 20mA. It is also the thinnest, brightest, and with a typical forward voltage of 3.2V, consumes the least power of any Cree standard size green LED chip. The XB-900 527nm version has a typical radiant flux of 30mW at 350mA, and the XB-900 505nm version has a typical radiant flux of 45mW at 350mA. Key uses for these products are white light applications using RGB technologies (where discrete red, green and blue LED's are combined to create white light), traffic signals and signage. Production quantities are now available for both products.
Mike Dunn, Vice President, Optoelectronics, stated, "We continue to respond to our customers' requirements for thinner and brighter LEDs with a lower forward voltage. These new products offer our customers exciting opportunities to target new applications and greater penetration into the white LED market."
Cree is an advanced semiconductor company that leverages its expertise in silicon carbide (SiC), gallium nitride (GaN) and silicon (Si) materials technology to produce new and enabling semiconductors. The products include blue, green and near ultraviolet (UV) light emitting diodes (LEDs), near UV lasers, radio frequency (RF) and microwave devices, and power switching devices. Potential applications for these products include solid-state illumination, optical storage, wireless infrastructure and power switching.
