<P>PROBLEM TO BE SOLVED: To solve the problem that supply current flowing to a light emitting diode is limited at Imax and electric power transmission using an infrared ray is impossible since an existing electric power transmission device using the infrared ray (refer to official report for patent No. 2001-316817 and patent No. 2002-106759, for example) performs an intermittent operation by a relation of heat generation. <P>SOLUTION: Large electric power of a long distance can be transmitted by a system of a light receiving element composite type using a spherical reflection mirror or an elliptical arc reflection type using a virtual elliptical focal point. Signals (digital or analog) are superimposed on an electric power transmission signal. Then, electric power and the signals can simultaneously be transmitted. <P>COPYRIGHT: (C)2004,JPO |
