Beschreibung
Zusammenfassung:	The invention pertains to an exposure apparatus, a method for exposing a photosensitive element to radiation using the exposure apparatus, and a method for preparing a printing form from the photosensitive element. The exposure apparatus includes a base assembly having an exposure bed that supports the photosensitive element, and a lamp housing assembly having two or more lamps. The lamp housing assembly includes an air distribution assembly having an air chamber that is disposed adjacent to the lamps and pressurized to provide uniform distribution of air exiting the air chamber to impinge a backside of each of the lamps. The air exiting the chamber and impinging the lamps is controlled by monitoring the temperature of the lamps and/or the irradiance emitting from the lamps.
