Development of low cost lighting
A consortium led by Filtronic, and including QinetiQ, Forge Europa, Thomas Swan and Cambridge University, has won a three-year contract within the DTI technology program to develop a route to low cost LEDs for solid-state lighting.
High brightness LED lamps are a low cost, long life and efficient replacement for standard light bulbs, reducing energy requirements by at least 75%.
A major barrier to using LEDs is the relatively high cost. This project will use large-scale semiconductor processing methods for Gallium Nitride (GaN)-based light emitting structures grown on silicon substrates, to reduce costs and improve consistency.
The project will provide a step forward on the solid-state lighting roadmap and provide a route for the UK to enter this major future market.
