20140313497 | EXPOSURE APPARATUS AND A METHOD FOR CONTROLLING RADIATION FROM A LAMP FOR EXPOSING A PHOTOSENSITIVE ELEMENT - The invention pertains to an exposure apparatus, a method for controlling a photosensitive element to radiation using the exposure apparatus, and a method for exposing a photosensitive element to radiation. 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 adjustable ballast connected to at least one of the lamps to adjust power received by the one lamp, a sensor for measuring irradiance impinging the exposure bed; and a controller that adjusts the adjustable ballast based on comparison of the measured irradiance to the target irradiance, thereby adjusting the irradiance emitting from the lamp to the target irradiance. | 10-23-2014 |
20140315132 | EXPOSURE APPARATUS AND A METHOD FOR EXPOSING A PHOTOSENSITIVE ELEMENT AND A METHOD FOR PREPARING A PRINTING FORM FROM THE PHOTOSENSITIVE ELEMENT - 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. | 10-23-2014 |
