POWER AND SIGNAL CARRIER

摘要

PURPOSE:To carry power and signal safely by transmitting the power and the signal on light waves having different wavelengths. CONSTITUTION:Signals fed from a first circuit 102 to a second circuit 201 are modulated through a modulating means 105 and then converted into light through a second driving means 106 and a second light emitting means 107(wavelength 72). Light waves emitted from first and second light emitting means 103, 107 transmit through a light wave transmitting means 4 to a light wave separating means 202 in an auxiliary circuit 2. The light wave separating means 202 separates the light wave into two light wave components having wavelengths lambda1 and lambda2. The light wave having wavelength lambda1 is converted through a first photoelectric converting means 203 into electric power which is fed to a charging means 206. Light wave having wavelength lambda2 is converted through a second photoelectric converting means 204 into an electric signal which is then demodulated through a demodulating means 205. A second circuit 201 is operated by thus demodulated signal.
