IEEE Awards George Craford For Contributions To LED Lighting

Lumileds' Fellow to receive Edison Medal for pioneering developments that ushered in the era of solid state lighting
Lumileds has announced that George Craford, Lumileds Solid State Lighting Fellow, was selected for the IEEE Edison Medal for "˜a lifetime of pioneering contributions to the development and commercialisation of visible LED materials and devices'.

Craford will be presented with the medal at the IEEE Honours Ceremony in San Francisco on May 25, 2017, during the IEEE Vision, Innovations, and Challenges (IEEE VIC) Summit.

Craford's career spans from the early days when LEDs were first developed to delivery of high brightness LEDs suitable for commercial use in a variety of applications, including LED bulbs. He is best known for his invention of the yellow LED in 1972. Craford then led the development of increasingly brighter red, orange and amber LEDs.

In 1979, Craford began work at Hewlett-Packard, where his team pioneered the development of AlInGaP LEDs using metalorganic chemical vapor deposition (MOCVD). MOCVD was then a relatively expensive lower volume process and had not been used for the high volume commercial production of LEDs. AlInGaP LEDs increased the performance of red and yellow LEDs by more than ten times. Craford's team continued to achieve technology breakthroughs in AlInGaP LEDs, eventually reaching 100 lm/W.

"Not only was George responsible for substantial breakthroughs in technology, but with his team, ensured that the technology could be reliably and cost effectively manufactured," said Mark Karol, 2017 IEEE Awards Board Chair.

One can see the impact of Craford's early work in the colour LEDs now ubiquitous in traffic signals, emergency and automotive lighting. Craford's later work focused on making white LED light cost effective for retail, office, architectural, outdoor and industrial lighting markets. In the early 2000s, his team's work enabled commercialisation of the first high power LEDs in the 10-20 lumen range. Such LEDs contributed to the creation of the first LED bulbs to meet the high efficiency and long lifecycle requirements to win the US Department of Energy's 'L Prize' for a 60W-equivalent LED bulb.

"George has terrific instinct for what will work, but at the same time he's got that practical engineering side that drives a solution until it produces the best results," said Jy Bhardwaj,CTO of Lumileds.

Today, Craford is Lumileds Solid State Lighting Fellow at Lumileds. He is an IEEE Life Fellow and a member of the National Academy of Engineering. He has received numerous awards including the 2002 National Medal of Technology and the 2015 US National Academy of Engineering Charles Stark Draper Prize.

He has also been awarded the International SSL Alliance Global Solid State Lighting Development Award, the Strategies in Light LED Pioneer Award, the University of Illinois Alumni Distinguished Service Award, the IEEE Morris N. Liebmann Award, the IEEE Third Millennium Medal, the Optical Society of America Nick Holonyak Jr. Award, the International Symposium on Compound Semiconductors Welker Award, the Materials Research Society MRS medal, the Electrochemical Society Electronic Division Award and the Economist Innovation Award.



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.
