Abstract
The present invention provides improved methods and apparatus for irradiating a product with light of a specific wavelength to activate the photoactive agent that is contained therein. To this end, in an embodiment, a device is provided that comprises a source of radiation including a plurality of light emitting diodes. Each light emitting diode includes a body portion through which radiation is transmitted. The body of the diode is surrounded by a fluid. In this regard, a first housing is provided that includes an interior that contains the light emitting diodes and a fluid. The housing includes a transparent window for allowing radiation generated by the light emitting diodes to flow through the window and irradiate a product that is in juxtaposition to the window.
