1. A UV lamp module for the ultraviolet irradiation of a substrate, comprising:
a lamp arrangement that includes multiple low-pressure mercury lamps each having a longitudinal axis;
a waterproof housing surrounding the lamp arrangement and having a bottom side, a top side and at least two side walls connecting the bottom side and the top side to each other, and a beam exit opening on the bottom side which is closed by a beam exit window;
a first airflow zone formed in the housing and having an air supply duct with at least one air-guide for the supply of cooling air to the lamp arrangement; and
a second airflow zone, which is separated from the first airflow zone, formed in the housing and having an exhaust air duct for the discharge of heated cooling air,
wherein, viewed in a cross-section through the housing perpendicular to the longitudinal axes of the low-pressure mercury lamps and in a viewing direction from the bottom side to the top side, the beam exit window, the lamp arrangement and the airflow zones are arranged one after the other; and
wherein the lamp arrangement has a center, and in that the supply air duct extends along the housing from an end connector to a gas distribution chamber arranged in the middle of the housing and above the center of the lamp arrangement.
