US DOE SSL R+D Workshop

I recently presented at and attended the US Department of Energy’s Solid State Lighting 2014 R+D Workshop in Tampa, Florida.  A terrific event, the US DOE’s SSL group uses this input from key industry participants to help guide their long-term funding programs with the goal of promoting the adoption of energy-efficient LED and OLED lighting technologies. You can find my slide deck here:  20140106_BK_DOESSL_2014 Workshop_Tampa_V3_extra annotations We need to find ways to reduce the total costs of advanced lighting systems.  And as big a fan as I am regarding digital lighting technologies, I want our industry to leave behind a positive … Continue reading US DOE SSL R+D Workshop

transphorm – GaN power electronics

I just found an interesting 2011 article from MIT’s Technology Review :  A startup called Transphorm is using GaN power electronics to substantially reduce power converter sizes. The possibility of using gallium nitride in power electronics has been known for decades, but producing high-quality versions of the material has been a challenge. That problem, however, was largely solved by researchers who figured out how to use gallium nitride in LEDs, Mishra says. Transphorm has optimized the material for power electronics, and it has developed novel devices (such as transistors), circuits, and complete modules that include all the components needed to … Continue reading transphorm – GaN power electronics
