Patent ID: 7373535

Claim:
An electric power saving apparatus, using light energy, having infrared ray synthetic wavelengths connected in parallel with a transmission line connecting an alternating current power supply and a load, and that is provided with a semiconductor device adapted in order to transmit light energy with infrared ray synthetic wavelengths to the transmission line as an output pulse signal; said electric power saving apparatus comprising: a rectifying part disposed between the alternating current power, and an input terminal of the semiconductor device, for the purposes of rectifying the alternating current into a direct current of low voltage; a control part, having a circuit adapted to apply a driving voltage at the direct low voltage current of the rectifying part to the semiconductor device, and having the semiconductor device; an oscillation-limiting part disposed at the carrier circuit between the transmission line connecting the alternating current power and the load, and an output terminal of the semiconductor device, for the purposes of generating the output pulse signal corresponding with a frequency of the alternating current power; and an infrared ray emitting diode, disposed near the semiconductor device in such a manner as to be controlled by the output of the control part, having the semiconductor device mounted on a circuit board constituting the electric power saving apparatus, for the purposes of irradiating the infrared rays emitted therefrom to the semiconductor device, such that while the circuit board constituting the electric power saving apparatus is being assembled, the light energy from the infrared ray synthetic wavelengths of a specific wavelength band is irradiated to the semiconductor device in order to excite photon-absorbing electrons to a conduction band, and to vary the electrical state in the interior of the crystal of the semiconductor device; and while the electric power saving apparatus is in operation after being connected in parallel with the transmission line connecting the alternating current power and the load, the infrared ray energy is continuously supplied to the semiconductor device.
