PROBLEM TO BE SOLVED: To provide a therapeutic and/or diagnostic light source comprising a non-planar array of light emitting diodes conformed to the shape of an external area to be treated or diagnosed. SOLUTION: A therapeutic light source for photodynamic therapy (PDT) comprises air-cooled LEDs Lx, y, and the air is exhausted in the vicinity of the array. The array may be mounted to the distal end of a hand piece suitable for invasive therapy. The LEDs may be coupled to light guides W, L. The emission spectra of the LEDs may be limited to a range of 550 to 660 nm, preferably to one of the ranges 590 to 640 nm, 560 to 644 nm, 650 to 660 nm, and 550 to 570 nm. The therapeutic light source may comprise a non-planar array of light-emitting diodes conformed to the shape of an external area to be treated. The therapeutic light source may comprise a non-planar array of independently switchable red and blue light emitting diodes mounted on a flexible backing. COPYRIGHT: (C)2006,JPO&NCIPI
