Claim 3:
4. The apparatus for irradiating a substrate according to claim 1, wherein on a top side of each irradiation module, one or more irradiation module cooling medium inlet openings are provided for supplying not yet heated, fresh irradiation module cooling medium from the platform, wherein the irradiation module cooling medium inlet openings of each irradiation module are functionally arranged and configured so as to operate in tandem with outlet openings of the platform for not yet heated and fresh irradiation module cooling medium, wherein the irradiation module cooling medium inlet openings are connected to the end regions of a lamp located in the region of the front side and/or the back side of the apparatus in a manner so as to guide not yet heated and fresh cooling medium, wherein, below the lamp, for providing of a gas-tight closure of the outlet opening of the irradiation module as well as for providing of guiding the irradiation module cooling medium in a closed circuit within the irradiation module, a fully or partially transparent pane for radiation emitted by the lamp and, above the lamp, a reflector, with or without cooling fins or a heat exchanger, are provided, wherein not yet heated, fresh irradiation module cooling medium is supplied to the respective open end region of a gap between a lower glass pane and the reflector, said end region being located in the direction of the back side of the apparatus and/or in the direction of the front side of the apparatus, wherein, in a center region of the irradiation module, said center region being located, when viewed from the side of the irradiation module above the reflector and/or the cooling fins and/or the heat exchanger, a guide is provided for discharge of the irradiation module cooling medium heated after full or partial as well as one-time or repeated overcoating of the lamp, said discharge being directed vertically upward in the direction of the platform.
