Cree Smashes R&D Record With 276 Lpw LED

The III-nitride LED, grown on SiC (silicon carbide), beats the firm's previous record of 254 lumens per watt
Cree claims it has hit another industry first with a barrier-breaking 276 lumen-per-watt white R&D power LED.


This significant milestone exceeds Cree’s previous R&D industry record of 254 lumens per watt and demonstrates Cree’s continued commitment to innovate and accelerate the adoption of LED lighting.


Cree’s innovative SC³ Technology Platform, available today in Cree XLamp LEDs, enables this record-breaking R&D result. The SC³ Technology Platform features advancements in LED chip architecture and phosphor and boasts a new package design to deliver the most advanced LED components in the industry.


Cree reports that the LED efficacy was measured at 276 lumens per watt, at a correlated colour temperature of 4401 K and 350 mA.


“The core of the Cree R&D culture is a relentless focus on innovation that ultimately drives LED adoption," says John Edmond, Cree co-founder and director of advanced optoelectronics. “The innovation from our labs is the foundation for our lighting-class XLamp LEDs. Higher performance LEDs can enable new and better LED-based applications and drive down the solution cost of LED designs."




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.
