<P>PROBLEM TO BE SOLVED: To provide a compact self-ballasted fluorescent lamp capable of enhancing reliability of a lighting device by efficiently radiating heat in a cover body to the outside and protecting an electronic component. <P>SOLUTION: A wrapping pin 53 with a lead wire 43a extending from an electrode 43 as a heat source wound around and an inner wall of the cover body 10 are made in contact with each other by a thermal conductive substance. Therefore, the heat is not radiated excessively in a space in the cover body 10, is conducted to the cover body 10 through the thermal conductive substance, and is efficiently radiated from an outer surface of the cover body 10 to the outside. <P>COPYRIGHT: (C)2004,JPO |
