<p><P>PROBLEM TO BE SOLVED: To solve the defect that there is still room for improvement in self-help capability regarding a fault and a trouble in an electric bulb, a fluorescent lamp or the like. <P>SOLUTION: "A reusable electric-bulb, a reusable fluorescent lamp or the like, and a separable circuit" are respectively configured as follows. A spare (3) of a filament (2), in which a fault or a trouble likely occurs, in a group of components of an electric bulb, a fluorescent lamp or the like is prepared inside the electric bulb, the fluorescent lamp or the like so as to extend its service lifetime. A rotary electrical outlet type circuit (9) is provided to the electric bulb, the fluorescent lamp or the like such that each shape of the electric bulb, the fluorescent lamp or the like is left as it is. The rotary electrical outlet type circuit is configured to allow a user to finally select a circuit electrically conducted from the filament or the spare of the filament. When the electric bulb, the fluorescent lamp or the like is located at a place out of reach of a person, the rotary electrical outlet type circuit (9) is made separable and separated from a body so as to be operable at hand. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
