ST IVES-based Prism Electronics Limited has won a contract that will help to create the next generation of high brightness light-emitting diodes (LEDs) - highly energy-efficient lighting that can significantly reduce greenhouse gas emissions when used in place of conventional lighting. Prism - a contract electronics manufacturing services provider - is to supply a range of printed circuit board (PCB) assemblies to a Cambridge-based supplier of manufacturing equipment for the semiconductor industry. The new supply agreement builds on a long-standing contract under which Prism already manufacturers a number of PCBs for the company and provides spares for several of its long-established systems. Prism said the market for high brightness LEDs was still in its infancy and the firm was continuing to help technology companies in research and development projects in support of changing market requirements. David Dickin, business development director at Prism Electronics, said: "We are delighted that this [contract] is because our production expertise and flexibility allow us to match our schedules to our customer's manufacturing and R & D needs.
