A new technique that paves the way for manufacturing affordable LED light bulbs is to be exploited in the UK, in a deal that researchers say could have a dramatic impact on carbon emissions.
Researchers estimate that a worldwide switch to LEDs, which are far more energy-efficient, would enable the closure of 560 power plants and result in annual CO2 savings equivalent to the output of all the cars on the planet.
LEDs are also being designed to give off a more natural quality of light, which will be better for people’s health.
“We’ve got higher efficiency for growing gallium nitride on silicon than anyone else we know,” Humphreys said. “Potentially this is a deal that puts Britain right at the forefront of LED research.”
“LED light bulbs currently cost as much as £40, but we expect to be able to reduce that cost by a factor of five by growing on silicon.
