<P>PROBLEM TO BE SOLVED: To provide an LED illuminator with an induction current as a power supply simultaneously using a power supply for transmitting an electromagnetic wave which can be saved in resource, improved in economy, high in safety, long in service life, and short in lighting time, thus substantially eliminating the exchange of a bulb. <P>SOLUTION: The LED illuminator uses an induction current as a power supply simultaneously using a portable power supply for transmitting an electromagnetic wave. An LED, since it is extremely reduced in power consumption, can be lit by the induction current generated by the electromagnetic wave. It is one of the biggest features that, in a conventional illuminator, a power supply and a switch must be connected to each other, but in the basic embodiment, a power supply and a switch do not exist. When there is no user of an electric lamp, the power supply is not necessarily required to exist because this LED illuminator is a device which is used in a place where no illuminator is required. RFID (Radio Frequency Identification) which is used for the control of the LED illuminator and has been frequently used in these years reads data of a semiconductor memory in a non-contact manner by using an induction electromagnetic field or an electric wave, and performs short-distance communication for writing. <P>COPYRIGHT: (C)2008,JPO&INPIT |
