A lighting system (10) for generating an illumination product comprises an excitation source, blue/UV LED, (1 1) operable to generate excitation radiation (17) and a remotely located phosphor, photo luminescent material (14). Excitation radiation (17) is guided from the excitation source (11) to the phosphor (14) by a waveguiding medium (12), the waveguiding medium (12) being configured such that the distance the radiation travels from the excitation source (11) to the phosphor layer (14) is at least one centimeter in length. The UV/blue excitation source (11) provides excitation radiation (17) to the phosphor(s), causing the phosphor(s) to photo luminesce, and i may also provide a component (18a) of the final illumination product (18a, 18b, 18c). The configuration of the waveguide allows a greater flexibility in lighting system configurations, such as hanging lighting fixtures, desk lighting fixtures, floor standing lighting fixtures, desk lamps, track lighting, spot lighting, accent lighting, lighting panels, inspection lamps and endoscopes. |
