<P>PROBLEM TO BE SOLVED: To provide a self-powered lighting equipment that stores and supplies electric energy by itself. <P>SOLUTION: The self-powered lighting equipment includes a lamplight source 1 and a self-powered collection set 2. The lamplight source includes a light shade 11, a casing 12, and a light emitting element 13 in the casing 12. The self-powered collection set is composed of a power collection plate 21, a controller 22, an energy storage device 23, and a current converting switch 24. A plurality of power collection plates 21 is arranged inside a lampshade of the lamplight source. The power collection plate converts the light emitted from the light emitting element 13 into electric energy. Inside the casing, there are installed the controller 22, the energy storage device 23, and the current converting switch 24. Also, two circuits of a current A circuit 242 and a current B circuit 243 are installed. The electric energy absorbed from the plurality of power collection plates 21 is stored in the energy storage device 23. The energy storage device 23 can feed electric energy to the current converting switch 24 via a detective switch 241, supply electric energy to the light emitting element 13 via the current A circuit 242, receive electric energy from an external power source, and supply electric energy to the light emitting element 13 via the current B circuit 243. <P>COPYRIGHT: (C)2011,JPO&INPIT |
