<p>The present invention provides improved methods and apparatus for irradiating a product with light of specific wavelength to activate the photoactive agent that is contained in the product. To this end, in an embodiment, a device (22, 24) is provided that comprises a source of radiation including a plurality of light emitting diodes (36). Each light emitting diode includes a body portion through which radiation is transmitted. The body of the diode (36) is surrounded by a fluid (43). In this regard, a first housing (26) is provided that includes an interior (34) that contains the light emitting diodes (36) and a fluid (43). The housing (26) includes a transparent window (42) for allowing radiation generated by the light emitting diodes (36) to flow through the window (42) and irradiate a product (18) that is in juxtaposition to the window (42).</p> |
