Claim 5:
6. The apparatus for irradiating a substrate according to claim 5, wherein one or more conduits for guiding not yet heated, fresh irradiation module cooling medium open into the platform or are integrated into the platform, wherein, in the one or more conduits, outside and/or inside the platform, one or more ventilators and/or pumps are respectively provided, wherein these conduits extend in the platform when viewed from a side in the direction of a center region of the platform, wherein the conduits, indirectly via a central guide or directly, open into an outlet opening located in the center region of the platform on the bottom side of the platform, wherein, on a top side and in the center region of the irradiation module, one or more inlet openings, corresponding to the outlet opening on the bottom side of the platform and cooperating therewith, are provided for not yet heated, fresh irradiation module cooling medium exiting from the platform, wherein downstream of the central inlet opening into the irradiation module a vertical, downwardly facing guide is provided for guiding the not yet heated, fresh irradiation module cooling medium from the outlet opening on the bottom side of the platform, wherein, in the lower end region of this guide, an apparatus is provided for splitting the vertically downwardly flowing irradiation module cooling medium flow into an irradiation module cooling medium partial flow directed in the direction of the back side and into an irradiation module cooling medium partial flow directed in the direction of the front side of the apparatus, wherein each of these irradiation module cooling medium partial flows, while flowing in the direction of the respective end region open to the back side or front side through the cooling fins or heat exchanger indirectly or directly connected to the back side of the reflector, then flows through the respective front side or back side end region with the electrical contacts for a power supply of the lamp, then flows through an emitter region located above the lamp between the bottom of the reflector and the top of the lamp, proceeding from the front side or back side end region, in the direction of the center of the irradiation module, then flows around the lamp in a vertical, downwardly facing direction and in the direction of the glass pane closing the radiation outlet opening, then flows through the emitter region located below the lamp between the glass pane and the bottom of the lamp, wherein, downstream thereof, one or more front side and/or back side guides are provided for the vertical, upwardly directed guiding of the heated irradiation module cooling medium partial flow in the direction of one or more outlet openings located on the top side of the irradiation module, wherein one or more inlet openings are provided on the bottom side of the platform for the heated irradiation module cooling medium, flowing out of the outlet openings located on the upper side of the irradiation module, wherein said inlet openings of the platform for heated irradiation module cooling medium are connected to conduits for guiding heated irradiation module cooling medium through the platform into a region located outside the platform.
