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.


 


 




AngelTech Live III: Join us on 12 April 2021!

AngelTech Live III will be broadcast on 12 April 2021, 10am BST, rebroadcast on 14 April (10am CTT) and 16 April (10am PST) and will feature online versions of the market-leading physical events: CS International and PIC International PLUS a brand new Silicon Semiconductor International Track!

Thanks to the great diversity of the semiconductor industry, we are always chasing new markets and developing a range of exciting technologies.

2021 is no different. Over the last few months interest in deep-UV LEDs has rocketed, due to its capability to disinfect and sanitise areas and combat Covid-19. We shall consider a roadmap for this device, along with technologies for boosting its output.

We shall also look at microLEDs, a display with many wonderful attributes, identifying processes for handling the mass transfer of tiny emitters that hold the key to commercialisation of this technology.

We shall also discuss electrification of transportation, underpinned by wide bandgap power electronics and supported by blue lasers that are ideal for processing copper.

Additional areas we will cover include the development of GaN ICs, to improve the reach of power electronics; the great strides that have been made with gallium oxide; and a look at new materials, such as cubic GaN and AlScN.

Having attracted 1500 delegates over the last 2 online summits, the 3rd event promises to be even bigger and better – with 3 interactive sessions over 1 day and will once again prove to be a key event across the semiconductor and photonic integrated circuits calendar.

So make sure you sign up today and discover the latest cutting edge developments across the compound semiconductor and integrated photonics value chain.
