Cree Releases Commercial XLamp XP-E High Efficiency White LEDs

Cree, Inc., a company focusing on LED lighting, has announced the commercial availability of XLamp XP-E High Efficiency White (HEW) LEDs. The new high-efficiency components extend the light output and efficacy of the XLamp XP-E LED family , enabling fixture designs that can use up to 50 percent fewer LEDs, which the Company noted can help drive down costs for fixture and bulb manufacturers while delivering the same system performance. Cree reported that XP-E HEW LEDs are optimized to lower initial costs for diffuse lighting applications, such as LED replacement lamps and down lights. For example, an A-19 lamp that uses XP-E LEDs could be re-designed to use half as many XP-E HEW LEDs while maintaining the same efficacy.
XLamp XP-E High Efficiency White led street lighting Manufacturer are high-powered LEDs featuring Cree's new Direct Attach LED technology. The Company said that Direct Attach technology is Cree's, next-generation LED chip technology that delivers higher flux, lower forward voltage, and lower thermal resistance .
  "With 500 percent more die-attach area and an order-of-magnitude less die under-fill, Direct Attach technology is far more robust than any other LED flip chip technology in the market today," said John Edmond, Cree director of advanced optoelectronics. "For our customers, these attributes, combined with the performance advantages of Direct Attach technology, can translate to brighter, more reliable lamps and fixtures, developed at a lower cost."
XLamp XP-E High Efficiency White LEDs deliver up to 148 lumens in cool white (6500K) and 114 lumens in warm white (3000K) at 350 mA. In addition to light output and efficacy improvements, Cree noted that XP-E HEW LEDs feature a reduced thermal resistance of 6 degrees C / W. XP-E HEW LEDs are available in the same white variations as XP-E LEDs, including Standard White, Outdoor White and 80-CRI White.
  XLamp XP-E High Efficiency White led street light wholesale are available now in sample and production quantities with standard lead times. The Company reported that IES LM-80 data for measuring lumen maintenance of LED light sources, for XP-E HEW LEDs, is targeted for availability in February 2011.
