Title:
METHOD AND APPARATUS FOR EXTRACTING EXCESSIVE OPTICAL ENERGY OF ILLUMINATOR
Document Type and Number:
Japanese Patent JPS58100464
Kind Code:
A
Abstract:
PURPOSE:To reutilize the power of a solar cell mounted to the illuminator, and to conserve power by absorbing beams in the direction unnecessary for illumination by the solar cell. CONSTITUTION:The optical energy 3a of sections having no effect on illuminance among excessive optical energy 3 irradiated from the illuminators 2 of every kind lit through supply from a commerical power supply 1 is converted into DC voltage by means of the solar cell 4 while a power supply 5 which directly reutilizes said DC voltage or converts said DC voltage into voltage currents corresponding to electric apparatus used and reutilizes them is obtained. DC currents generated by means of the solar cell 4 can hardly be used under a state that they are left as they are because voltage is low and currents are also smaller than the commercial power supply 1. A large number of the solar cells 4 are connected in parallel and series and power is increased, voltage is boosted or dropped, currents are converted into AC by employing an inverter 6, voltage is boosted or dropped up to desirable voltage through a transformer 7, AC are converted into DC by means of a rectifying circuit 8 and accumulated to a battery 9 once, and the electric energy is utilized.
