Cree high power LEDs improve light output by 50 percent

July 15, 2015 // By Paul Buckley
Cree, Inc's XLamp XHP35 family of LEDs have achieved a 50 percent improvement in light output compared with Cree’s previous highest-performing single-die LED. The company claims the device sets a new performance standard for the 3.5 mm footprint.

Built on Cree’s SC5 Technology platform, the XHP35 LED introduces Cree’s breakthrough high-voltage power die architecture, empowering manufacturers to unleash the full capacity of extreme high power LEDs using existing drivers. The new XHP35 LED delivers up to 1,833 lumens without the optical inefficiencies of a multi-die LED to enable new designs with reduced size and lower system costs.

Unlike other existing high power LEDs, the XHP35 family of LEDs uses a 12 V monolithic power die to deliver extreme high power performance at drive currents at or less than 1 A, making the use of high power LEDs more accessible for lighting designers. The improvement is enabled by Cree’s SC5 Technology Platform built on Cree’s industry-leading silicon carbide technology and features significant advancements in epitaxial structure, chip architecture and an advanced light conversion system optimized for best thermal and optical performance.

The XHP35 LEDs are available in high density and high intensity versions that are optimized to deliver the maximum performance for specific applications. The XHP35 High Density LED delivers new levels of light output in the compact XP footprint for high lumen applications, such as outdoor and high bay lighting. The XHP35 High Intensity LED is optimized to deliver maximum candela through secondary optics to boost performance and reduce size for applications requiring high light intensity, such as stadium, torch and track lighting.

Samples of both XLamp XHP35 and XHP35 High Intensity LEDs are available now, and production quantities are available with standard lead times. The XHP35 LEDs are available in 70, 80 and 90 CRI and color temperatures ranging from 2700K to 8300K with 2-step and 3-step EasyWhite options.
