Cree Claims Its Single-die LEDs Are Industry’s Brightest

The XLamp XM-L2 LEDs, based on the firm's SiC (silicon carbide) technology, deliver 186 lumens-per-Watt
Cree says it has once again set an LED industry performance milestone with the commercial availability of its XLamp XM-L2 LEDs.

The new XM-L2 LED delivers up to 186 lumens-per-watt at 350 mA, 25°C, a level of performance available only in a lab setting just three years prior.

Built on Cree’s proprietary revolutionary SC³ Technology next-generation LED platform, the new XM-L2 LEDs double the lumens-per-dollar and deliver 20 percent more lumens-per-watt over the original XM-L LED. This enables lighting manufacturers to use fewer LEDs to deliver a better lighting system for lower cost.

The new XM-L2 LEDs are designed for very-high-lumen applications such as indoor, high-bay and outdoor lighting. The high-performance XM-L2 LEDs are compatible with existing XM-L LED designs and leverage the 5 mm x 5 mm XM footprint . This allows customers to easily incorporate the XM-L2 LEDs into existing XM LED designs to shorten the fixture design cycle and improve time-to-market.

“We’re excited that Cree has improved the performance of the XM package with the XLamp XM-L2 LED," says Jeff Rogers, vice president of sales and marketing, Musco Sports Lighting. “XM-L2 allows us to boost the performance of our existing XM-L designs without changing optics or drivers."

The XM-L2 LED offers the unique combination of very high efficacy and high drive currents, delivering an unprecedented 1198 lumens at 116 lumens-per-watt efficacy at 3 A, 25°C. The XM-L2 is the eighth product built on Cree’s SC³ Technology platform.

The platform leverages Cree’s advanced silicon-carbide technology and features advancements in LED chip architecture and phosphor. It boasts a new package design to deliver the most-advanced LED components in the industry.

“The XM-L2 LED efficiently delivers hundreds of lumens per LED, allowing us to significantly reduce the number of LEDs in our designs," comments Steve Walczak, director of engineering, Sternberg Lighting. “By using fewer LEDs, we can simplify design and production, ultimately reducing cost without sacrificing light output or quality for our end customers."

Characterised at 85°C, the XM-L2 LED is available in 2700K to 6200K colour temperatures and offers minimum CRI options of 80, 85 and 90. What's more, since the XM-L2 LED is a successor product to XM-L LEDs, the application of ENERGY STAR qualification requires only 3000 hours of XM-L2 LED LM-80 data, instead of the normal 6000 hours. The XM-L2 LED is also UL-recognised and features a level-4 rating.

Cree XLamp XM-L2 LED 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.
