Abstract
This invention provides an improved light-operated telephone that comprises a solar array battery subsidizer or charger and a battery subsidized or charged by the solar array battery subsidizer or charger. The solar array battery subsidizer or charger comprises a solar array, power regulators connected to the solar array, negative and positive battery charging contacts connected to the power regulators, a housing in which the battery charging contacts are positioned and means for transmitting light connecting the solar array to the power regulators and connecting the power regulators to the battery charging contacts. In a preferred embodiment, the improved light-operated telephone has a double-sourced power. The solar rechargeable battery is one source of power (i.e. a primary power source) and is positioned in a primary cell which serves as a solar rechargeable battery compartment and is preferably covered by a crystal plate. In addition, a non-solar rechargeable battery is a secondary power source and is positioned in a secondary cell which serves as a non-solar rechargeable battery compartment. The first requirement for the operation of the solar array battery subsidizer is a light source. Light, received by photoelectric sensors, is converted into electromagnetic two-way power by the solar array. Voltage charge is controlled and regulated by the power regulators which avoid overcharge of the batteries. Light is transferred from the solar array to the power regulators and from the power regulators to the negative and positive battery charging contacts via the means for transmitting light. The solar battery is recharged or subsidized by the solar array battery subsidizer upon contacting the negative and positive battery charging contacts.
