Abstract:
1. A lighting system comprising: a light emitting flexible sheet that comprises a plurality of flexible elongate light transmissive waveguides, each said flexible waveguide having a light emitting surface; at least one phosphor provided over at least a part of the light emitting surface of said flexible waveguide and a plurality of light emitting diodes, each said light emitting diode operable to generate blue excitation light having a peak emission wavelength greater than 450 nm, the lighting system being configured such that excitation light is coupled into the waveguides such that said excitation light propagates through said flexible waveguide and is then emitted through the light emitting surface and wherein at least a part of the excitation radiation excites the at least one phosphor which emits light of a different color, wherein the illumination product of the system is a combination of the excitation light and photo luminescent light emitted by the at least one phosphor.
