Solar-Controlled Light Device
US Patent:
7994735, Aug 9, 2011
Filed:
Jul 22, 2009
Appl. No.:
12/507240
Inventors:
Amy S. Berman - San Diego CA, US
Michael Feder - San Diego CA, US
Eric D. Smith - San Diego CA, US
Michael Feder - San Diego CA, US
Eric D. Smith - San Diego CA, US
International Classification:
H05B 37/02
US Classification:
315297, 315355
Abstract:
A solar-controlled light device with a circuit-control having a phototransistor, a first resistor, and a first transistor connected to a storage unit, to a solar cell, and to a current-control. 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 boost the power as needed to a sufficient level to power the lights.

International Classification:
F21L 4/00
US Classification:
362183
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.
