Hybrid fibre lighting - directed towards a smaller ecological footprint

Hybrid fibre lighting systems comprise light-emitting diodes (LEDs) in combination with a solar fibre optic system and they have great energy savings potential. Over the expected lifetime of the light source, a reduction in electricity consumption of 59% can be achieved compared with fluorescent tubes, and 36% compared with LEDs. However, the project has also shown that key components such as the solar collectors are still so expensive that the total price of the system remains a barrier to practical application. As significant reductions in prices are likely in the near future, the project group will continue their work on, amongst other things, improving the light emission intensity and colour reproduction in Elforsk projekt 343-036.
