Blue LEDs Feature Dual-Chip Redundancy
 |
| The reliability and brightness of a series of blue seven-segment LEDs will benefit life-support systems and other critical medical equipment. |
Blue seven-segment light-emitting diodes (LEDs) that integrate two chips in series have been introduced for critical applications such as life-support systems. The 1.0-in. displays developed by BivarOpto, the optoelectronics division of Bivar Inc. (Irvine, CA, USA), feature reliable performance and visual appeal.
The BD Blue–series units use high-efficiency InGaN chips to maximize light extraction while operating at low current. The materials are lead-free, and the products are manufactured in compliance with WEEE and RoHS specifications.
Available in a range of five digit heights, the displays come in 24 different styles and models. Connection options and the choice of common anode or cathode circuitry enable all numeric display configurations. Right- or left-hand decimals and 18 alpha characters can be accommodated. The standard wavelength is 465 nm peak.
“The redundant dual-chip design in each segment ensures reliable performance and light distribution,” says Anthony Vilgiate, vice president, strategic business development. “The chip’s inherent strength creates enhanced brightness at this wavelength,” he adds.
