Delivers improved efficiency and greater output

By Warren Miller, contributing writer

Cree, Inc. has introduced
a new high-efficacy (HE) edition of the XLamp XP-G2 LED, a progression that the
company claims yields greater output and higher efficiency than its
predecessors. The XP-G2 HE can be easily configured into existing XP-G2 LED
systems, allowing designers to upgrade their indoor/outdoor, portable, and
architectural applications with Cree’s latest Dmax high-power LED chip technology. These improvements “enable
smaller, lighter, and lower-cost designs,” said Cree.

Based on Cree’s SC3 technology platform, the
XP-G2 LED produces up to 20% more lumens per watt and two-and-a-half times the
lumens-per-dollar than first-generation XP-G LEDs. The newest XP-G2 HE LED,
leveraging the Dmax high-power chip technology, provides up to 9% greater
efficacy and lower thermal resistance while producing 25% more light output (by
way of a maximum current of 2,000 mA) than preceding XP designs. Optically
compatible with original XP-G designs, the XP-G2 can be dropped into
pre-existing systems to reduce LED design cycles and get products to market
more quickly.

“The
XLamp XP-G2 LED served as a breakthrough product that enabled a broad set
of new LED applications,” stated Dave Emerson, executive vice president and
general manager of Cree’s LED product line. “Today, Cree continues our
commitment to make our latest LED technology available in form factors that are
easy for our customers to use while enabling smaller, lighter, lower-cost
designs and delivering the color quality that Cree is known for. Cree’s new
XP-G2 HE further strengthens the industry’s best 3.45-mm high-power LED
portfolio, which delivers leading lumen density and reliability for high-power
general lighting applications.”

Perhaps
the most visible application for high-power lighting is in the architectural
space. Dramatic LED-based lighting on modern buildings provides the opportunity
to create “personalities” for buildings that mirror their occupant’s branding.
More cost- and power-efficient LEDs can now expand these applications to even
smaller, more cost-sensitive structures or provide even more dramatic effects
on larger buildings.
