) is separated from the lamp case 3) by pulling the lamp case 3), and the power supply plug (15) is inserted into a socket in the room to charge the lamp. )
Effects of the Invention Therefore, according to the present invention, even if dirt or oxide film forms on the surface of the power supply terminal inside the power supply case due to long-term use, the leads of the light case are removed every time the power supply case is integrated with the lamp case. The power receiving contact on the board rubs against the six semicircular areas of the power supply terminal that are not selected, thereby removing dirt and oxide film and ensuring electrical continuity between the power supply terminal and the lead plate. It is possible to obtain a highly reliable light bulb that can reliably supply power to the light bulb without causing poor conductivity between the two.
