Claim 13:
14. 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 has a peripheral shoulder and is closed by a beam exit window adhesively bonded to the peripheral shoulder;
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 the first airflow zone is arranged upstream of the second airflow zone, and
wherein a lower connector of the air supply duct and an upper connector of the exhaust air duct protrude from one closing wall of the housing.
