SANTA CLARA, Calif.—(BUSINESS WIRE)—June 28, 2007— World light-emitting diode (LED) technology leader, OSRAM Opto Semiconductors, is developing a low current, high-power green 1 mm2 chip, featuring the latest in ThinGaN technology. With unprecedented brightness values of more than 180 lm, the new green chip will be used in the company's DRAGON(R) and OSTAR(R) LEDs, and is targeted for LCD display backlighting applications.
"A new epitaxial process and improved chip design, as well as low
power consumption, have given this new green chip a major boost in
efficiency and brightness that makes it ideal for display backlighting
applications," Dr. Matthias Peter, development engineer at OSRAM Opto
The new 180 lm green chip from OSRAM has a power consumption of
1.4 W, achieves 72 lm/W, and features a wavelength of 527 nm from an
operating current of 1 A. In comparison, the existing green Platinum
DRAGON(R) LED produces 100 lm from an operating current of 1 A.
With a current range of 100 to 350mA, and a power consumption of 1
W, the new green chip from OSRAM provides an efficient and cool base,
as well as uniform and increased brightness over large display
diagonals with less LEDs.
The new green chips from OSRAM are expected to go into series
production by the third quarter of 2008.
