  • Solar-powered lighting system
    Patent number: 8519639
    Abstract: An improved, solar-controlled light device with a circuit-control having a phototransistor, a variable resistor, and a first transistor connected to a storage unit, to a solar cell, and to a current-control. The variable resistor can be set to permit the device to turn on at pre-set ambient light levels. The current-control has a transformer, a second resistor, and a second transistor, connected at one end of the current-control to a light and at another end connected to the circuit-control, wherein the current-control senses the amount of power and boosts the power as needed to a sufficient level to power the lights.
    Type: Grant
