Abstract: Ionization apparatus including a housing, a high voltage source having a high voltage terminal and a ground return terminal, an ionization electrode inside the housing electrically connected to the high voltage terminal and a grounding wire mounted to the exterior surface of the housing and electrically connected to the ground return terminal.

Abstract: An insect electrocution device comprising a lamp and an insect electrocution assembly disposed in generally surrounding relationship with at least a portion of the lamp. In particular, an insect electrocution device comprising a lamp for attracting insects and an insect electrocution assembly disposed about the lamp, the insect electrocution assembly comprising an outer apertured plate, the area of the apertures being substantially less than the remaining area of the plate, and inner electrode apparatus spaced from the outer apertured plate. There is also disclosed a combination illumination device and insect electrocution device including a lamp having peak outputs in both the UV region for insect attraction and in the visible region for effective illumination.
