Photonics can transform the UK, says IOP report launched on global day of light
"The photonics industry already contributes �13bn to the UK economy and employs 65,000 people"
"Fenella Frost, from PhotonStar LED Group plc, said there had been a rapid increase in the efficiency of LEDs, which were becoming cheaper and lasting longer. LEDs now achieved an efficiency of 140 lumens per watt but developers had a target to achieve 200 lm/W by 2020. Almost every building now has LED lighting, she said, and one of the applications is in providing lighting to help people bring their body clock back into line with natural Circadian rhythms, especially in settings for elderly people. Research in this area focused on how to deliver what is effectively a drug, i.e. suitably tailored lighting, she said."
