<p>A light system (1) including a collector (2) made of a sheet of material having a fluorescent substance incorporated therein, the system also including an elongated optical element (3) jusxtaposed adjacent the collector (2). Light incident on the collector (2) induces fluorescence that is trapped by total internal reflection (TIR), concentrated, and radiated from an output edge (9) of the collector (2). The elongated optical element (3) modifies the distribution of light output from the output edge (9) and preferably configured to decrease divergence of such light. The collector (2) design can be veried to include a stack of layers or a series of segments that fluoresce at different wavelengths so as to produce multicolored light.</p> |
