Abstract

PROBLEM TO BE SOLVED: To improve the convenience of the use and eliminate wasteful consumption of electric power by controlling this foot lamp as to be automatically turned on, only in the case the surrounding is dark and a person has been detected and at the same time, forming plug blade-insertion holes as a receptacle. SOLUTION: After a human body detecting circuit 13a amplifies the output from a heating coil sensor 13, the amplified output is compared with a standard voltage by a comparator 13a2 and in the case the output is equal to or higher than the standard voltage, a human detection signal is transmitted to a signal-processing circuit 17. On the other hand, a luminance sensor 14 transmits a Low signal or a High signal, in the case the luminance in the surrounding is not higher than a prescribed value or not lower than the prescribed value, respectively, to a signal processing circuit 17. In the case the human being detecting signal is transmitted and only when the signal from the luminance sensor 14 is the Low signal, does the signal transmit processing circuit 17 a lighting signal to a lighting circuit 12a. In response to that, a light-emitting part 121 is lighted only for a prescribed duration from the leading up of the human body signal and then extinguished. Moreover, plug blade-insertion holes are formed in the surface of a box shaped body 10 and plug blade-receptions 11a are formed in the inside, so that plug blade-insertion inlets are provided, even in the case this foot lamp 1 is inserted into a receptacle in the wall face.
