Cree high-density discrete LED ups the stakes

The compact XLamp XB-H III-nitride based LED is claimed to deliver excellent lumen density and optical control
Cree is introducing the XLamp XB-H LED, the brightest discrete in Cree’s high-density (HD) class of LEDs.

The company says it delivers a breakthrough combination of lumen output and efficacy in a small package. The XB-H LED brings the lighting-class performance of the XP-G2 LED into a package that is 50 percent smaller.

Delivering more than 500 lumens at 1.5 A, 25º C in a 2.45 x 2.45-mm package, the Cree XB-H LED can enable luminaires that use the same-size-footprint XB-D LED to triple their light output at the same efficacy.

XLamp XB-H LEDThe XB-H joins the XQ-E in the family of HD-class discrete LEDs that offer the industry’s highest optical control factor (OCF), a measurement of how LED size and performance benefit directional lighting applications.

High-OCF LEDs enable lighting manufacturers to improve the performance of any lighting design, create smaller and less-expensive systems, and develop new lighting solutions that were previously not possible.

“Cree is the first LED manufacturer to bring this level of performance to such a small size,” says Roger Suen, supply chain management director, Light Engine Ltd. “With a high optical control factor, the XB-H LEDs enable new levels of brightness and optical control to improve design flexibility, increase performance and lower system cost without sacrificing reliability.”

Utilising Cree’s ceramic-package technology, the new XB-H LED delivers long L70 lifetimes at both high temperature and current. In addition, the XB-H offers compatibility with most optics designed for the Cree XP family of LEDs, allowing lighting manufacturers to leverage the optics of existing lighting designs and improve time-to-market.

“We are excited to offer our breakthrough high-density performance to manufacturers who prefer to work with discrete LEDs,” says Dave Emerson, vice president and general manager for Cree LEDs. “Delivering up to 175 lumens-per-watt efficacy at 1 W, 25° C in its small package, the XB-H LED sets a new performance standard for high-power LEDs. Our new HD class of discrete LEDs demonstrates Cree’s commitment to offering customers the best options for their applications.”

To improve time-to-market, lighting manufacturers seeking ENERGY STAR qualification can take advantage of the XB-H LED’s successor status to the XP-G2 LED-meaning that ENERGY STAR qualification can be achieved using just 3,000 hours of LM-80 data, instead of the normal 6,000 hours.

The XLamp XB-H LED is available in colour temperatures ranging from 2700 K to 8300 K and CRI options of 70, 80, 85 and 90. Binned at 700 mA, 85° C, the XB-H LED delivers up to 499 lumens at 5 W, 85° C.

Product samples are available now and production quantities are available with standard lead times.

 

 

Connecting the Compound Semiconductor Industry

The 13th CS International conference builds on the strengths of its predecessors, with around 40 leaders from industry and academia delivering presentations that fall within five key themes: Ultrafast Communication; Making Headway with the MicroLED; Taking the Power from Silicon, New Vectors for the VCSEL, and Ultra-wide Bandgap Devices.

Delegates attending these sessions will gain insight into device technology, find out about the current status and the roadmap for the compound semiconductor industry, and discover the latest advances in tools and processes that will drive up fab yields and throughputs.
