Luminus Adds Eleven High-intensity IR LEDs

News

Dual-junction technology allows double the power density in the same footprint

Luminus Devices, a Californian firm using technology from MIT, has expanded its portfolio of high-power IR LEDs with eleven emitters designed to address the rapid expansion of automotive, consumer, machine vision, medical, and security applications.

The Luminus IR SST LEDs are now offered in three wavelengths - 810nm, 850nm, and 940nm - and six beam angle options ranging from 40° to 130°. The high radiometric power output and low thermal resistance allow system designers to reduce the number of emitters and overall footprint for a broad range of infrared applications.

Nine of the newly-introduced IR products are based on dual-junction technology which nearly doubles the power density and keeps efficiency virtually unchanged. This makes it easier to develop solutions with much higher radiant intensity and more compact designs. The IR SST product line delivers very high radiometric power, up to 1600 mW typical at 850 nm and 1 A drive current, and radiant intensity in excess of 1300 mW/sr.

“Our dual-junction technology allows us to double the power density in the same footprint,” said Yves Bertic, senior director of global product marketing. “Now product designers can address applications that need longer reach and more intense and focused beams.”

Optical options have also been expanded to support the increasing variety of infrared applications.

A small, 40°, beam angle is the perfect replacement for legacy 2mm to 5mm through-hole IR LEDs, and the broadest beam angle, 130°, is ideal for flood illumination that is more common in security applications. Whether for biometric applications or monitoring for security, this latest generation of IR LEDs supports ongoing industry development and reduces time to market.
