Abstract
A fluorescent lamp and ballast assembly is designed to thermally isolate a ballast circuit from the illuminated lamp and thereby reduce the heat surrounding the ballast circuit. The fluorescent lamp of the assembly is attached to a housing that reduces the heat transferred to the ballast circuit. The housing includes a bowl-shaped member, a shield, and a thermal isolation member connected between the bowl-shaped member and the shield. The bowl-shaped member is designed to hold and encircle the electronic ballast circuit, and the shield is designed to engage and secure the fluorescent lamp and attached cathode lead wires of the invention. The thermal isolation member is connected between the bowl-shaped member and the shield, and provides an air gap between the lamp and the ballast circuit. The air gap allows ventilation between the lamp and the ballast circuit and also provides a greater distance between the lamp and the ballast circuit to protect the ballast circuit from the heat generated by the energized lamp.
