Abstract: The invention relates to a lamp system comprising a low-pressure mercury vapor discharge lamp having a discharge vessel (6) enclosing a discharge space (8), with two electrodes (10, 30) positioned in the discharge vessel and an amalgam (18) arranged at a first end section (28) outside the discharge path between the first electrode and the second electrode. A ballast generates an electrical discharge current independently of an electrical heating current. A heating element (22) is positioned in the first end section for heating the amalgam using the electrical heating current. The temperature of the amalgam can be kept within its optimal temperature range for a relatively broad range of operating conditions.

Abstract: The present disclosure provides for systems and methods for disinfecting of components of an HVAC system. At least one non-linear UV light source is positioned within the HVAC system. A non-linear UV light source can include but is not limited to a spherical bulb lamp or a circular lamp. Non-linear UV light sources are positioned about desired HVAC components to deliver UV light to the surface of those components thereby preventing unwanted biological growth. A plurality of non-linear light sources can be positioned throughout the HVAC system including about a heating or cooling coil apparatus, an air moving apparatus such as a fan positioned within an air duct and/or within the air duct to disinfect air flow passing through the air duct.
