Cree develops 170 lumen-per-watt LED light bulb prototype
August 03, 2012 // By Christoph Hammerschmidt
Showcasing its 152 lumens-per-watt concept LED bulb, Cree raised the bar with the 170 lumens-per-watt (LPW) prototype LED light bulb.
The innovations behind the high-performance 170 LPW LED bulb are enabling significantly higher efficacy and lower cost for Cree's luminaire portfolio. According to Cree, this level of performance has been made possible by advancements across all elements of the LED lighting system – lighting-class LEDs, optics, drivers and thermal management. LEDs based on Cree's SC³ Technology Platform enable this R&D lighting result.
The SC³ Technology Platform is built upon Cree’s silicon carbide technology and features advancements in the LED chip architecture and phosphor.
“Optimizing 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 170 LPW concept LED bulb is enabling us to develop higher-performance and lower-cost Cree LED luminaires.”
Third party testing by independent lab OnSpeX confirmed that Cree’s new 170 lumen-per-watt prototype LED bulb delivered more than 1250 lumens and consumes only 7.3 watts. The bulb uses Cree's TrueWhite Technology to deliver a CRI of 90+. As an efficiency comparison, a traditional 75-Watt incandescent light bulb produces 1100 lumens, which is only 14.6 lumens per watt.
