New IR LEDs feature high drive currents of 1.5 A and 5.0 A (pulsed), greater radiant power, and a 50° emitter for narrower IR emission.
Lumileds introduced new additions to the LUXEON IR Domed Line that offer a significant increase in both DC and pulse drive current – up to 1.5 A and 5.0 A, respectively. The new emitters deliver radiant power of 1350 mW at 850 nm wavelength (slightly visible) or 1450 mW at 940 nm (invisible or covert IR). These new IR LEDs are engineered to withstand higher power so that clearer 3D imaging is possible using fewer LEDs in critical infrared (IR) applications.
“Smaller, higher resolution surveillance cameras have smaller lens apertures and smaller pixel size on the image sensors. These systems need more light to function properly. The high drive capable LUXEON IR Domed Line LEDs significantly increases light output for a wide variety of IR applications,” said Alvin Yeoh, Senior Product Marketing Manager at Lumileds. “Drop-in replacement for existing designs is a snap with the standard 3.7 by 3.7 mm footprint. Applications such as biometric identification, virtual reality/augmented reality headsets, machine vision and surveillance cameras will benefit immediately from the power boost.”

In addition to high drive capability, a new 50° emitter is now a part of the portfolio. Along with the 60°, 90°and 150° emitters, these IR LEDs will serve high punch, long range or wide scanning applications, including face recognition for security and access controls. Lumileds low resistivity package (2.5 W/°C) removes heat more efficiently from the emitter, enabling even more compact camera designs and higher reliability than its competitors.
