LED-array light source for medical therapy

摘要

Abstract: mitting diode (LED) array light sources currently in development offer an alternative to laser light sources in a wide range of medical applications. Previously developed as light sources for research in photosynthesis in plant growth experimentation, LED arrays have produced an average continuous output of 4 - 6 watts at a wavelength of 660 nm. This output is equivalent to the terrestrially sensed output of the sun at this wavelength at high noon. LED chips are arrayed on an alumina tile substrate that may be formed to provide optical power focused on a specified target area. !9
