A recently granted patent (Publication Number: US11857686B2) discloses a UV lamp module designed for the ultraviolet irradiation of substrates. The module includes a lamp arrangement with multiple low-pressure mercury lamps enclosed in a waterproof housing. The housing features a unique design with separate airflow zones for cooling and exhaust, ensuring efficient operation. The airflow zones are strategically positioned within the housing, with the lamp arrangement at the center and a gas distribution chamber for cooling air supply. The module is configured to produce a UV irradiation intensity of at least 100 mW/cm2 on the substrate, making it suitable for disinfection applications in packaging material for food or medicines.

The patent also details additional features of the UV lamp module, such as a reflector surrounding the lamp arrangement and a beam exit window closed by a beam exit window adhesively bonded to a peripheral shoulder. The housing exhibits mirror symmetry and a curvature on the top side, enhancing the overall efficiency and performance of the module. The design ensures optimal airflow through the air supply duct and exhaust air duct, with identical inner diameters for efficient cooling. The module's innovative design and functionality make it a valuable addition to disinfection systems requiring ultraviolet irradiation for packaging material in sensitive industries like food and medicine, highlighting its potential for enhancing safety and quality standards in these sectors.
