A radiation source for emitting high intensity light close to the emitting surface thereof, includes a thermally conductive substrate (3); a densely packed two dimensional array (1) of light emitting diodes formed on a surface of the substrate, the emission spectrum of the array being matched to that required by a particular application of the radiation source; means for applying relatively high drive currents to each of the diodes; and heat sinking means (8), such as a water cooled heat sink, for dissipating the heat generated by the diodes. <IMAGE> |
