Cree Reveals 170 Lumens Per Watt LED Bulb

The US semiconductor manufacturer says breakthrough innovations have optimised performance and driven costs down.

Cree has unveiled a 170L/W prototype LED light bulb, less than a year after showcasing the 152L/W concept LED bulb.

The innovations behind the high-performance 170L/W LED bulb are enabling significantly higher efficacy and lower costs, says Cree.

And as the company also points out, the latest development demonstrates the its commitment to accelerate the adoption of LED lighting by addressing initial cost and payback, key barriers to widespread LED lighting adoption.

The LEDs are based on Cree's so-called SC³ Technology Platform, including silicon carbide technology and feature advancements in the LED chip architecture and phosphor.

“Optimising each LED design element was critical in achieving the performance reached by Cree’s new prototype LED bulb," said Nick Medendorp, vice president of research and development, Cree lighting.

“The technology embodied in the new 170L/W concept LED bulb is enabling us to develop higher-performance and lower-cost Cree LED luminaires. By pushing the limits of what is possible, Cree continues to strive to develop new technology that uses less energy and provides unmatched light quality and value to our customers," he added.

Third party testing by independent lab OnSpeX confirmed that the new 170L/W prototype LED bulb delivered more than 1250 lumens and consumes only 7.3W.

The bulb uses Cree TrueWhite Technology to deliver a CRI of 90+.

As an efficiency comparison, a traditional 75W incandescent light bulb produces 1100 lumens, which is only 14.6L/W.

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.
