TY - JOUR AB - Electrical power consumption in buildings may be reduced considerably by more efficient use of sunlight for indoor lighting. A stack of luminescent solar concentrator sheets has been developed, which utilises three different coloured fluorescent dyes to produce a concentrated near-white light source to be coupled into flexible polymer sheets and transported up to 10m. Thus in clear sky conditions a remote room with neither walls nor roof in direct contact with the sun, can be illuminated by over 1000lm of natural light with a luminous efficacy of over 300lm/W, regardless of the sun's position. © 2004 Elsevier B.V.
