Abstract

PURPOSE: To prevent lighting circuit components stored in a cover from being damaged by heat and extend their lives by forming a metallic thin film on the outer surface of the cover of a fluorescent lamp device.
CONSTITUTION: A metallic thin film 25 with excellent heat conductivity such as aluminum is formed on the outer surface of the cover 1 of a fluorescent lamp device. The heat of the cover 1 is discharged to the outside by the heat radiating action of the metallic thin film 25. In this case, a heat radiating paint film 26 such as a white paint is formed on the outer surface of the metallic thin film 25, this film 26 dissolves the luster of the thin film 25 and further improves the heat radiation property of the thin film 25. The heat of the cover 1 is satisfactorily discharged to the outside. The temperature rise in the cover 1 is thereby suppressed, the thermal adverse effect on lighting circuit components 12 and 13 is mitigated, the lighting circuit components are prevented from being damaged by heat, and their lives can be extended.
