Consortium wins £3m to pursue led lighting

A consortium of Filtronic, Forge Europa, QinetiQ, Thomas Swan and Cambridge University, has won a three year contract worth close to £3million to develop a route to low cost leds for solid state lighting.


The project goal is to demonstrate high quality leds on 150mm silicon substrates. This is likely to enable large scale production of led lamps for solid state white lighting. Replacement of conventional lighting by solid-state lamps has the potential to offer major savings in electricity use with a reduced environmental impact.
According to the partners, the key to adoption of the technology is cost and their project addresses the development of low cost solutions by exploiting large diameter substrates and the consistency of mature proven volume production in the UK.
The project combines proven expertise in commodity III-V semiconductor manufacture with some of the foremost capabilities within the UK for GaN growth, together with fundamental science and expertise in packaging and led marketing.
Funded under the DTI’s technology programme, the project will not only achieve significant progress on the solid state lighting roadmap, but also provide a route for the UK to enter this major future market.
