Abstract
A device for soft irradiation comprising a reflector having a cross-section in the shape of a spiral and an electromagnetic radiation source positioned off-axis such that the source is shielded from direct view. A cooling vent and openings provide impingement cooling of the source to allow efficient use of a high intensity radiation source. Cooling of the source may be further improved with the addition of one or more fluid moving devices in flow communication with the reflector. Optical reflectance coatings on the surface of the reflector or transmission filters allow the device to provide radiation output in selective bandwidths. Multiple reflectors may be used in combination to evenly illuminate complex or large surfaces. There are specific utilities to this design with both pulsed and continuous light sources.
