Santa Clara, Calif.Light-emitting diode (LED) technology company, OSRAM Opto Semiconductors, is developing a low current, high-power green 1 mm²-chip, featuring the latest in ThinGaN technology.
With brightness values of more than 180 lm, the green chip will be used in the company's Dragon and Ostar LEDs, and is targeted for LCD display backlighting applications.
The 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 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.
Availability: The green chips from OSRAM are expected to go into series production by the third quarter of 2008.
